This application claims the priority to Chinese Patent Application No. 202411897854.4 filed with the Chinese Patent Office on Dec. 20, 2024 and entitled “FALSE EYELASHES AND MANUFACTURING METHOD THEREOF”, which is incorporated herein by reference in its entirety.
The present invention relates to the technical field of false eyelash manufacturing, and in particular to false eyelashes and a manufacturing method thereof.
As a beauty modification product, false eyelashes are an important part of makeup. With the improvement of the economy, people's demand for beauty has become stronger, and the market demand for false eyelashes has also grown significantly.
However, the current manufacturing of false eyelashes generally relies on tedious manual production. Links of false eyelashes such as pressing and processing the hair materials, combining the hair materials, cleaning the roots, and fixing the hair materials to the base, require a lot of manual participation. This results in low production efficiency and places high demands on the accuracy of manual operations. As a result, the yield rate is low, limiting the expansion of the production scale of false eyelashes and making it difficult to meet the current market demand for false eyelashes.
At the same time, false eyelashes are usually composed of hair materials and stems. The hair material is used to determine the style and shape of the false eyelashes. The stem determines the product quality of the false eyelashes and the wearing comfort of consumers. Therefore, if there is a problem with either the hair material or the stem during the production process, the quality of the finished false eyelashes may be affected.
For example, during the process of pressing the hair materials, manual operations are required to ensure that the hair materials are evenly and firmly bonded, or during the process of cleaning the roots, the operator must ensure that the roots are cleaned without damaging the hair materials, which requires high manual skills of the operator. For another example, for the existing false eyelashes, the hair materials need to be bonded to the stem, and the glue used for bonding may greatly limit the appearance and wearing comfort of the false eyelashes.
An objective of the present invention is to solve the problem that the existing false eyelash manufacturing process consumes labor costs and has low production efficiency. The present invention provides a manufacturing method of false eyelashes, which can produce an integrally formed false eyelash product with high production efficiency.
In order to solve the above technical problem, an embodiment of the present invention discloses a manufacturing method of false eyelashes, including:
According to another specific embodiment of the present invention, the shape of the clustered false eyelash includes a plurality of shapes of clustered false eyelashes, the integrally formed semi-finished false eyelash includes a plurality of semi-finished false eyelashes, and the manufacturing method of false eyelashes further includes:
According to another specific embodiment of the present invention, the laser printing includes ultraviolet laser printing.
An embodiment of the present invention discloses a manufacturing method of false eyelashes, including:
By adopting the above technical solution, firstly, for the false eyelash produced by the manufacturing method of false eyelashes of the embodiment of the present application, a base and a plurality of hair material groups are integrally formed. In this way, the traditional cumbersome processes such as pressing and processing the hair materials, combining the hair materials, cleaning the roots, and fixing the hair materials to the base can be omitted. In other words, there is no need to manually perform processes of pressing and processing the hair materials, combining the hair materials, cleaning the roots, and fixing the hair materials to the base, which reduces labor costs and effectively improves the production efficiency of false eyelashes.
Secondly, in the traditional manufacturing process, each hair material needs to be manually pasted to the mold evenly to obtain a single piece of semi-finished false eyelash. Such a single piece of semi-finished false eyelash cannot be used directly as a finished product, but it is necessary to further manually fix the single piece of semi-finished false eyelash to the base (such as the stem) (this process is a traditional process of fixing the hair materials to the base). In this way, a finished false eyelash that can be directly attached to the bottom of the human eyelashes can be obtained. Moreover, the above process requires high accuracy of manual operation.
In the manufacturing method of the embodiment of the present application, process the integrally-formed false eyelashes can be directly obtained by processing on the substrate by using a non-heat-applied processing method. Therefore, there is no need to perform traditional processes of pressing and processing the hair materials, combining the hair materials, and fixing the hair materials to the base, and high production efficiency is provided. Moreover, the manufacturing method of the embodiment of the present application does not require operation accuracy and has a high yield rate.
Further, the non-heat-applied processing method is used to manufacture false eyelashes in the manufacturing method of the embodiment of the present application, and the material of the substrate of the false eyelashes is not affected during the entire manufacturing process, so that a better processing effect can be produced.

An embodiment of the present invention discloses a manufacturing method of false eyelashes, including:
By adopting the above technical scheme, firstly, for the first false eyelashes produced by the manufacturing method of false eyelashes of the embodiment of the present application, the first base and the plurality of first hair material groups are integrally formed. In this way, the traditional cumbersome processes such as pressing and processing the hair materials, combining the hair materials, cleaning the roots, and fixing the hair materials to the base can be omitted.

Secondly, in the traditional manufacturing process, each hair material needs to be manually pasted to the mold evenly to obtain a single piece of semi-finished false eyelash. Such a single piece of semi-finished false eyelash cannot be used directly as a finished product, but it is necessary to further manually fix the single piece of semi-finished false eyelash to the base (such as the stem) (this process is a traditional process of fixing the hair materials to the base). In this way, a finished false eyelash that can be directly attached to the bottom of the human eyelashes can be obtained. Moreover, the above process requires high accuracy of manual operation.
However, in the manufacturing method of the embodiment of the present application, because the first integrally-formed false eyelashes can be formed on the substrate by directly processing by a non-heat-applied processing method, there is no need to perform traditional processes of pressing and processing the hair materials, combining the hair materials, and fixing the hair materials to the base, and high production efficiency is provided. Moreover, the manufacturing method of the embodiment of the present application does not require operation accuracy and has a high yield rate.
Further, the plurality of first false eyelashes can be stacked and connected along the thickness direction by using ultrasonic welding or a bonding process to obtain at least one second false eyelash, that is, the second false eyelash is a multi-layer structure, so that more design possibilities and flexibility can be provided for the production of false eyelashes.

For ordinary technicians in the art, the specific meanings of the above terms in this embodiment can be understood in specific circumstances.
In order to make the objective, technical solution, and advantages of the present invention clearer, the implementation of the present invention is further described in detail below with reference to the drawings.
The embodiment of the present application provides a manufacturing method of false eyelashes. The manufacturing method of false eyelashes in the embodiment of the present application aims to ensure that false eyelashes are integrally formed, thereby breaking the existing traditional manual process and improving production efficiency. In addition, the false eyelashes manufactured by the manufacturing method of false eyelashes in the embodiment of the present application have the advantages of being environmentally friendly, light, and highly comfortable.
To facilitate understanding of the technical solution of the embodiment of the present application, some concepts or terms involved in the embodiment of the present application are first explained.
The curl of false eyelashes refers to the degree of curvature of the false eyelashes, which is usually expressed in degrees. Specifically, taking one hair material of the false eyelashes as an example, the curl refers to an angle between the arc tangent of the curved part of the hair material and the horizontal line, and the angle determines the degree of curvature of the false eyelashes, that is, the curl.
In addition, the horizontal line is a theoretical reference line, and is used to provide a benchmark for describing the curl. The person skilled in the art can understand that the horizontal line can represent a plane on which the roots of the false eyelashes are placed when the false eyelashes are worn, or can represent a straight line parallel to the ground.
Embossing, also known as pneumatic embossing process or pneumatic mold pressing process, refers to the process of layering the hair materials of the false eyelashes by using a pneumatic mold (such as a pneumatic press knife, but not limited thereto). This process includes two important factors: air pressure and pressing. Pressing refers to the use of physical pressure to press the false eyelashes to create an uneven layered effect on the false eyelashes, so that the false eyelashes have a visual layered effect, which is more three-dimensional and fluffy. Air pressure is used to control and adjust the force applied by the pneumatic press knife to the false eyelashes, and is also the power source for driving the pneumatic press knife.
The two factors of pressing and air pressure complement each other and jointly achieve the layered effect of the false eyelashes. This layered effect can also be described as blooming, that is, the hair materials of the false eyelashes spread outward from the roots, and each hair material no longer points in the same direction, so that the false eyelashes as a whole are more three-dimensional, similar to the petals of a flower spreading outward.

The development of this patented technology is to reduce the manual production links of false eyelashes and get rid of the application of chemical reagents. The new process uses an ultraviolet laser marking machine and ultrasonic welding as the core processing technology. The processing is fast and simple, a large number of manual production links are eliminated, and mechanical equipment is used to complete the production process of false eyelashes.
The ultraviolet laser marking machine is a product in the laser marking machine series and is also a newly developed laser processing technology. Because a laser thermal processing technology is used by the traditional laser marking machine, the improvement space in terms of precision is limited. However, cold processing is used by the ultraviolet laser marking machine, and therefore the precision is improved, and the thermal impact is minimized. This marks a significant leap in laser technology.
Ultraviolet laser processing is called cold processing because the high-energy molecules of ultraviolet photons directly separate the molecules on the metal or non-metallic materials to be processed. However, this separation causes the molecules to separate from the material. This working method does not generate heat. Because this type of processing method does not generate high heat, it is different from traditional lasers.
On the basis of cold processing, the effect of processing product materials will be better, and the processed products obtained by using this processing technology will be better developed. When using cold laser processing, the probability of material impact is reduced to one percent, so that the advantages of the processing are fully applied, which is also a great improvement in laser technology. It is believed that ultraviolet lasers will gradually be widely used in the future laser market.
The specific process is as follows:
First, CAD drawing software is used, and some designed clustered false eyelashes are distributed in a certain size, such as 200 mm*200 mm, and several PVE (polyvinyl ethyl ether) plastic films of a certain thickness, such as 0.05 mm, with a specific size of 300 mm*200 mm are prepared. The designed false eyelash drawing data is transferred to the ultraviolet laser printer, XYZ axis calibration is performed, and printing is performed, and laser-hollowing is performed on some clustered false eyelashes, and this process is completed.
The plastic solidifies naturally, and several strips or sheets of integrally-formed false eyelashes are obtained by peeling off the plastic film. At this time, several strips or sheets of eyelashes can be removed from the plastic film.
In some possible implementations, the embodiment of the present application can also use stereolithography (SLA, StereoLithography), selective laser sintering (SLS, Selective Laser Sintering) and the like for laser printing to obtain semi-finished false eyelashes. This is not specifically limited in the embodiment of the present application. As long as the process of using laser printing to obtain semi-finished false eyelashes is used, the process belongs to the protection scope of the embodiment of the present application.
Next, we use the ultrasonic process to carry out the following processing procedure.
Ultrasonic welding principle: When ultrasonic waves act on the contact surface of the thermoplastic plastic, high-frequency vibrations of tens of thousands of times per second are generated. By using this high-frequency vibration with a certain amplitude, ultrasonic energy is transmitted to the welding area by using an upper weldment. Because the welding area, that is, the interface of the two to-be-welded parts, has a high acoustic resistance, local high temperature is generated. Due to the poor thermal conductivity of plastics, the heat cannot be dissipated in time, and is gathered in the welding area, causing the contact surfaces of the two plastic parts to melt rapidly. After a certain pressure is applied, the contact surfaces are fused into one. When the ultrasonic waves stop acting, the pressure is maintained for a few seconds to solidify the plastic material in the welding area, thus forming a solid molecular chain to achieve the purpose of welding. The welding strength can be close to the strength of the raw materials. The quality of ultrasonic plastic welding depends on three factors: the amplitude of the transducer welding head, the applied pressure, and the welding time. The welding time and the welding head pressure can be adjusted, and the amplitude is determined by the transducer and an ultrasonic horn. The interaction of these three quantities has an appropriate value. When the energy exceeds the appropriate value, and the melt amount of the plastic is large, the welded part may become deformed. If the energy is small, it is not easy to weld firmly, and the applied pressure cannot be too large. The pressure can be determined according to the actual force area, material, welding quantity, etc. For example, the side length, width, thickness and other factors of the welded part are taken into consideration. This optimal pressure is the product of the side length of the welded part and the optimal pressure per 1 mm of the edge. For example, in the actual production process, the optimal pressure value within the unit size can be determined first, and then combined with the welding length or area size, the overall optimal pressure can be calculated comprehensively.
The semi-finished false eyelashes in clusters or sheets are obtained by using the ultraviolet laser marking machine. The semi-finished false eyelashes in clusters or pieces are welded together by using the principle of ultrasonic welding. After this process, a stacked combination of a plurality of semi-finished products can be obtained by processing the single-piece false eyelash semi-finished product, so that the amount of false eyelashes and the changes in styles by several times are increased, and the needs of various consumer groups of false eyelashes are also met.
The production process is as follows: A pre-moistened high-humidity, strong cotton paper of a specified size, such as 13 g, is placed at a designated position on the operating table, and it is ensured that the paper is laid flat on the table and any excess water is scrapped off. 1-2 semi-finished products that have been pressed and formed are placed at the designated position on the cotton paper. An aluminum alloy hollow rod of a corresponding size is used, at the lower end of the cotton paper, the cotton paper and the aluminum alloy hollow rod are pinched with both hands to roll vertically towards the upper end of the operating table until the rod rolls over the upper end of the cotton paper, and then the operation is completed. Finally, the aluminum alloy hollow rods with the rolled false eyelashes in batches are placed into a high-temperature steamer or a drying and sterilizing box, the temperature is adjusted to 110° C.-180° C., and the time is 60 min-120 min. After heating, the power is turned off, and the aluminum alloy hollow rods are allowed to cool naturally in the box to the room temperature about 23° C., then the batches of aluminum alloy hollow rods are taken out from the box. Finally, the workers manually remove the shaped false eyelashes from the aluminum alloy hollow rods.
The embossing process is to transform false eyelashes with a single curl into ones with a multi-layer messy appearance. After high-temperature shaping, the false eyelashes with a single curl can be obtained. A pneumatic press knife is used, and cutting is performed vertically downward in a manner of aligning with a position approximately 0.5 mm to 3 mm above the stem of the false eyelash. The air pressure determines the blooming size of the same style of false eyelashes. The greater the air pressure, the greater the multi-layer effect of the same style of false eyelashes. Different types of knives determine different blooming effects. Usually, there are flat knives, serrated knives, and wavy knives. Each type of knife is corresponding to a blooming effect. Finally, different hair materials of the false eyelashes also have different blooming effects. Usually, false eyelashes are divided into two effects of PET (polyethylene terephthalate) and PBT (polybutylene terephthalate). PET is a hard plastic relative to PBT. The blooming size of PET is often larger than that of PBT material, and the blooming effect of PBT is often more natural and beautiful.
Finally, packaging is carried out.
The manufacturing method of false eyelashes of the embodiment of the present application is described in detail below with reference to the accompanying drawings and specific embodiments.

S100: Provide a substrate 110.
In this step, the substrate 110 required for manufacturing false eyelashes is selected and prepared.
Exemplarily, the number of substrates 110 is not specifically limited in the embodiment of the present application. For example, one, two, four, five, etc. substrates 110 can be prepared. Selection can be made according to actual applications.
In some possible embodiments, the substrate 110 required in the embodiment of the present application includes but is not limited to the polymer such as a plastic film, a rayon film, or a nylon film.
The plastic film includes but is not limited to: a polyethylene (PE) film, a polyethylene terephthalate (PET) film, a polypropylene (PP) film, a polyurethane (PU) film, or a polyvinyl ethyl ether (PVE) film.
The polyethylene (PE) film and the polypropylene (PP) film are light and flexible. The polyethylene terephthalate (PET) film has good toughness. The polyurethane (PU) film is soft and durable. The polyvinyl ethyl ether (PVE) film has good adhesion and durability, and is more easily degraded.
Similarly, the rayon film has a texture similar to natural eyelashes, and a more natural appearance and a more comfortable wearing experience can be provided by using the rayon film as the substrate 110. The nylon film has good elasticity and strength, and higher durability and wearing comfort can be provided by using the nylon film as the substrate 110.
In this step, a polyvinyl ethyl ether (PVE) plastic film 111 with a thickness of 0.05 mm and a size of 300 mm*200 mm is selected as the substrate 110, but it is not limited thereto. Any one of the above types of plastic films, or the rayon film or the nylon film can be selected. Alternatively, any combination of these types of plastic films or the rayon film or the nylon film may be selected. For example, three substrates 110 are provided in the same batch of manufacturing, any combination of the types of plastic films can be used for two substrates 110, and the rayon film or the nylon film can be used for the other substrate 110. In addition, the thickness and size of the selected substrate 110 can also be selected according to the actual application. The polyvinyl ethyl ether (PVE) plastic film 111 is used as an example for explanation in the following text.

S200: Process a pre-designed false eyelash design pattern 210 on the substrate 110 by using a non-heat-applied processing method.
Based on the above step S100, as shown in
It can be seen that the false eyelash design pattern 210 includes: a hair material group pattern 211 and a base pattern 212 that are connected to each other. In this step, the non-heat-applied processing method is used to process the outline of each false eyelash design pattern 210 (that is, the outlines of a plurality of hair material group patterns 211 and the base pattern 212) on the polyvinyl ethyl ether (PVE) plastic film 111.
It should be noted that the hair material group pattern 211 and the base pattern 212 of the embodiment of the present application include but are not limited to the following design methods. As long as the design methods ensure that the hair material group pattern 211 and the base pattern 212 do not fall off after being processed on the substrate 110 by the non-heat-applied processing method, the design methods all belong to the protection scope of the embodiment of the present application, and can be selected according to the needs of consumers.

Further, the six hair material patterns 2111 of each hair material group pattern 211 shown in

Specifically, referring to
In addition, this design method can be understood as that a plurality of hair material group patterns 211 can correspond to a plurality of base patterns 212, and the number of hair material group patterns 211 is greater than the number of base patterns 212.

Similar to
Referring to
That is, in this design method, it can be understood that a plurality of hair material group patterns 211 can be corresponding to a plurality of base patterns 212, and the number of hair material group patterns 211 is less than the number of base patterns 212.
Referring to
Exemplarily, the six hair material patterns 2111 of a hair material group pattern 211 shown in
Referring to
Specifically, it can be seen that some hair material patterns 2111 in the hair material group pattern 211 cross each other. Because the hair material group pattern 211 is processed on the polyvinyl ethyl ether (PVE) plastic film 111 by using a non-heat-applied processing method, after the hair material group pattern 211 is processed, the hair material group formed by processing is not spread apart (that is, cross-connected). At the same time, the bases obtained by processing the three spaced base patterns 212 do not fall off by using the cross-connected hair material groups, that is, the integrally-formed false eyelashes can be obtained. Moreover, in the design method in which one hair material group pattern 211 is corresponding to a plurality of base patterns 212, the form in which the plurality of base patterns 212 are spaced from each other as shown in

In addition, the embodiment of the present application does not impose any specific restrictions on the shape of the base pattern 212. For example, the base pattern 212 may be rectangular, or may be elliptical, semicircular, circular, arc-shaped, etc., which may be selected according to the actual application scenario.
For example, referring to
For another example, one hair material group pattern 211 and a plurality of (for example, two) base patterns 212 can also be designed, the hair material group pattern 211 also includes only one hair material pattern 2111, and the shape of the base patterns 212 is designed to facilitate attachment by the consumer.
In some possible embodiments, the non-heat-applied processing method includes: a non-heat-applied laser printing process. Exemplarily, the non-heat-applied laser printing process includes: ultraviolet laser printing or stereolithography printing.
It should be noted that, in the embodiment of the present application, the non-heat-applied laser printing process refers to a process in which heat is not applied to the polyvinyl ethyl ether (PVE) plastic film 111 and the false eyelash design pattern 210 thereon, and printing is performed on the basis of cold processing. The non-heat-applied laser printing process can also be understood as a laser printing process that does not generate high heat, that is, a small amount of heat may be generated during the laser printing process, but this small amount of heat does not affect the material and processing effect of the polyvinyl ethyl ether (PVE) plastic film 111 and the false eyelashes 10, which is different from traditional laser printing. It can be understood that this small amount of heat does not cause thermal damage to the plastic film, rayon film, and nylon film. Any amount of heat within a heat range that does not cause thermal damage to the base materials is included within the scope of protection of the embodiments of the present application.
Continuing to refer to
S300: Obtain false eyelashes 10.
Based on the above step S200, in this step, as shown in
Further, in this step, each false eyelash 10 includes: a plurality of hair material groups 11 and a base 12. It can be seen that the plurality of hair material groups 11 (for example, three hair material groups 11 shown in

Additionally, the plurality of hair material groups 11 and the base 12 are integrally formed by using a non-heat-applied processing method, and at least some hair material groups 11 in the plurality of hair material groups 11 protrude from the base 12.
It should be noted that the base of the embodiment of the present application can be understood as a component similar to a stem in the traditional sense, or can be understood as a part or position for attaching to the lower part of the natural eyelashes of the human eye. As long as it is a position that allows the false eyelashes 10 to be attached to the natural eyelashes of the human eye and a position for the integral formation of the hair material groups 11, the position falls within the scope of protection of the base 12 in the embodiments of the present application.
For example, the plurality of integrally formed false eyelashes 10 can be fixed in a packaging box 30 shown in
The specific implementation of the above step S200 is described in detail below with reference to the accompanying drawings.
Referring to
S201: Obtain design software.
In this step, graphic design software of the false eyelash design pattern 210 is selected. The graphic design software has graphic design and image editing functions.
For example, any one of computer-aided design (CAD, Computer-Aided Design), Photoshop image processing software, CorelDRAW graphic design software, etc. can be selected. The present application does not make specific restrictions on this. As long as the design software can design the false eyelash design pattern, the design software belongs to the protection scope of the embodiment of the present application. The CAD computer-aided design software shown in
Step S202: Divide to obtain at least one design area S of at least one false eyelash design pattern 210 based on a drawing size of the design software.
Based on the above step S201, in this step, based on the CAD computer-aided design software, a drawing size of, for example, 200 mm*200 mm is selected, and two design areas S corresponding to two false eyelash design patterns 210 are obtained by dividing in the drawing area. For example, design areas S of 100 mm*200 mm are respectively reserved for the two false eyelash design patterns 210.
The drawing size of the CAD computer-aided design software and the size of the design area S obtained by dividing for each false eyelash design pattern 210 are not specifically limited in the embodiment of the present application.
Step S203: Design an outline of the corresponding false eyelash design pattern 210 in at least one design area S.
As shown in
In some possible implementations, further in combination with
In addition, according to the foregoing content, in Embodiment 1, each false eyelash 10 is corresponding to a single false eyelash design pattern 210. In other words, the design idea of the false eyelash design pattern 210 is that drawing can be performed based on the fact that the false eyelash 10 is a single-layer structure. It can be seen that each false eyelash design pattern 210 is corresponding to a single-layer structure of the false eyelash 10, and therefore a plurality of false eyelash design patterns 210 do not need to be kept uniform. In other words, in the design process of the same batch, the size, shape, and density of the hair material of the plurality of false eyelash design patterns 210 can be different, or can be kept the same. This is not limited in the embodiment of the present application.
For example, the number of hair material group patterns 211 of the false eyelash design pattern 210, and the number of hair materials in each hair material group pattern 211 are not limited in the embodiment of the present application, and can be selected according to actual application requirements.
At the same time, exemplarily, the width and length of the outline of each hair material group pattern 211 of the false eyelash design pattern 210 and the width and length of the outline of the base pattern 212 can be arbitrarily selected and designed according to actual needs.
Exemplarily, the outline of the hair material in the hair material group pattern 211 can be linear or arc-shaped. Exemplarily, the outline of the base pattern 212 can be linear (for example, the linear base pattern 212 shown in
Step S204: Place the substrate into a non-heat-applied laser printing device.
Referring to
In some possible embodiments, ultraviolet laser printing is adopted by the non-heat-applied laser printing process of the embodiment of the present application. In this step, an ultraviolet laser printer (not shown in the figure) can be selected as the laser printing device.
Ultraviolet laser printing is a cold processing laser printing process. The surface of the polyvinyl ethyl ether (PVE) plastic film 111 is processed by primarily using high-energy ultraviolet photons, and such high-energy photons can break the chemical bonds of the molecules on the surface of the polyvinyl ether (PVE) plastic film 111, so that these molecules are separated from the surface of the polyvinyl ether (PVE) plastic film 111, thereby achieving the printing effect. Because the photon energy of the ultraviolet laser is high, a higher energy density can be produced in a smaller area. This higher energy density acts on the polyvinyl ethyl ether (PVE) plastic film 111, mainly through photochemical action rather than thermal action. Therefore, the temperature around the polyvinyl ethyl ether (PVE) plastic film 111 does not rise during the entire printing process.
The ultraviolet laser printing process used in the embodiment of the present application is different from the traditional laser printing process.
Specifically, first of all, according to the foregoing content, heat is not applied to the false eyelash design pattern 210 during the ultraviolet laser printing process, and therefore the polyvinyl ethyl ether (PVE) plastic film 111 and the material of the printed false eyelashes 10 are not affected, and the probability of material impact is effectively reduced.
Secondly, the ultraviolet laser printer used in the ultraviolet laser printing process is a device that uses ultraviolet laser for printing. Because the wavelength of ultraviolet laser is short and the beam is thin, the ultraviolet laser printing process is particularly suitable for printing precision objects such as false eyelashes, which have many styles, different hair thickness and density, and high precision requirements. At the same time, no chemical reagents are required during the printing process, and less volatile organic compounds are generated, so the ultraviolet laser printing process is more environmentally friendly.
In addition, the ultraviolet laser printer is fast and suitable for mass production. Therefore, on the basis of replacing the traditional cumbersome manual production and directly and efficiently printing out the integrally-formed false eyelashes 10, the production efficiency can be further improved.
In some possible embodiments, laser printing can also be performed for the non-heat-applied laser printing process of the embodiment of the present application by stereolithography (SLA, Stereolithography) to obtain semi-finished false eyelashes. This is not specifically limited in the embodiment of the present application. Any process that uses a non-heat-applied processing method to manufacture false eyelashes falls within the scope of protection of the embodiments of the present application.
Step S205: Transmit data of the at least one false eyelash design pattern 210 to the non-heat-applied laser printing device.
Referring to
Exemplarily, the data of the false eyelash design pattern 210 includes but is not limited to: drawing information of the CAD computer-aided design software (for example, a size of 200 mm*200 mm), outline information of the false eyelash design pattern 210 (for example, the width and length of the outlines of the hair material group pattern 211 and the base pattern 212 of the false eyelash design pattern 210), and the thickness, size, quantity, etc. of the polyvinyl ethyl ether (PVE) plastic film 111.
Step S206: Set printing parameters and calibrate the non-heat-applied laser printing device.
Referring to
Exemplarily, the printing parameters include but are not limited to: substrate type, ultraviolet laser power, printing speed, ultraviolet laser pulse frequency, etc.
Step S207: Based on the non-heat-applied laser printing device, obtain at least one integrally formed false eyelash by laser hollowing on the substrate according to the data.

Referring to
Step S301: Perform non-heating shaping on the false eyelashes.
In this step, non-heating shaping is performed on the two false eyelash design pattern 210 obtained by laser hollowing in the above step S200. It should be noted that in the embodiment of the present application, non-heating shaping refers to a shaping method that does not require the application of heat, that is, no heating operation is used in the entire non-heating shaping process.
For example, room temperature shaping can be used. Specifically, the special tissue paper is soaked with chemical reagents, the tissue paper is placed at a designated position on the operating table, and it is ensured that the paper is laid flat on the table and the excess chemical reagents are scraped off. Then two false eyelashes 10 are placed at the designated position on the tissue paper, a rod of a corresponding size (such as an aluminum alloy hollow rod, and for another example, a solid rod of another material, which is not limited in the embodiment of the present application) is used, at the lower end of the tissue paper, the tissue paper and the rod are pinched with both hands to roll vertically towards the upper end of the operating table until the rod rolls over the upper end of the tissue paper, and then the operation is completed. Let the rod with the rolled two false eyelashes 10 stand for 24 hours, and after the chemical reagent and the two false eyelashes 10 fully react, the operator takes out the two shaped false eyelashes 10 from the aluminum alloy hollow rod.
In some possible implementations, a high-temperature shaping method can be used. For example, the rod with the rolled false eyelashes is placed in a high-temperature steamer or a drying and sterilizing box, the temperature is controlled at 40° C. to 140° C. After heating for a certain period of time (for example, 60 min-120 min), the rod is allowed to cool naturally to room temperature. Finally, the operator takes out the two shaped false eyelashes 10 from the rod. Exemplarily, the above temperature can be adjusted to, for example, 40° C., 67.5° C., 99.2° C., 118° C., 123.7° C., 139° C., 140° C., etc.
Step S302: Obtain the false eyelashes with curl.
Based on the above step S301, in this step, two false eyelashes 10 with curl can be directly obtained after non-heating shaping.
That is, after non-heating shaping is performed on the false eyelashes 10, the hair material in a plurality of hair material groups 11 in the false eyelashes 10 are curled and shaped by using the rod, so that the false eyelashes 10 with a certain curl can be obtained. The embodiment of the present application does not limit the curl, and the curl is determined by the size specifications of the rod.
The size specifications of the rod include at least: the diameter of the round rod and the contact surface of the special-shaped rod.
That is, when a round rod is used, the curl of the false eyelashes 10 is determined by the diameter of the round rod. For example, if the length of the hair material of the obtained false eyelashes 10 is 16 mm, a rod with a diameter of 12 mm can be selected to obtain the false eyelashes 10 with a certain curl. If a larger curl needs to be obtained, the diameter of the rod can be reduced, and a rod with a diameter of, for example, 10 mm or 8 mm can be selected. For another example, if the length of the hair material of the obtained false eyelashes 10 is 14 mm, a rod with a diameter of 11 mm can be selected. This is not limited in the embodiment of the present application.
When a special-shaped rod is used, taking a spiral rod as an example, the curl of the false eyelashes 10 is determined by the contact surface between the false eyelashes 10 and the spiral rod. Differences in the spiral pitch, the number of spiral turns, and the spiral shape of the spiral rod result in variations in the contact surface available for the false eyelashes 10. Therefore, the degree of curvature produced after the false eyelashes 10 are in contact the contact surface also varies.
Referring to
Step S310: Perform non-heating shaping on the false eyelashes.
In this step, non-heating shaping is performed on the two false eyelash design patterns 210 obtained by laser hollowing in the above step S200.
It should be noted that in this step S310, the definition of non-heating shaping and the specific shaping process are the same as those of the above step S301. Details are not repeated herein.
Step S320: Perform embossing on the false eyelashes after non-heating shaping.
In this step, embossing is performed for the false eyelashes after non-heating shaping.
Specifically, the embossing process can transform two false eyelashes 10 with a single curl into ones with a multi-layer messy appearance. After the room temperature shaping of the above step S310, two false eyelashes 10 with a single curl can be obtained. At this time, a pneumatic press knife is used, and cutting is performed vertically downward in a manner of aligning with a position approximately 0.5 mm to 3 mm above the base 12 of each false eyelash 10, so that the hair materials in the hair material group 11 of each false eyelash 10 can obtain a blooming effect. It can be understood that the hair materials in the hair material group 11 produce a layered effect, so that the false eyelashes 10 are more three-dimensional and have a sense of depth.
For example, the size of the air pressure of the pneumatic press knife can determine the blooming size of the false eyelash 10. The greater the air pressure, the greater the multi-layer effect of the false eyelash 10. For example, the type of pneumatic press knife used can also determine the different blooming effects. For example, types of pneumatic press knives such as flat knives, serrated knives, wave knives, etc. can be used, and each type of pneumatic press knife is corresponding to a blooming effect.
It should be noted that the multi-layer of the false eyelashes 10 involved in this step refers to performing embossing on the hair material of the false eyelashes 10 with a single-layer structure, to give a visual multi-layer effect, but it does not mean that the false eyelashes 10 have a multi-layer structure.
Step S330: Obtain false eyelashes with curl and layering.
Based on the above step S320, in this step, two false eyelashes 10 with curl and layering are obtained after embossing.
That is, after non-heating shaping is performed on the false eyelashes 10, the hair materials in the plurality of hair material groups 11 in the false eyelashes 10 are curled and shaped by the rod, so that false eyelashes 10 with a certain curl can be obtained.
Further, embossing is performed on the false eyelashes 10 after non-heating shaping, so that the hair materials of the false eyelashes 10 produce a layered effect.
It should be noted that, as mentioned above, in Embodiment 1, the false eyelashes 10 are a single-layer structure, that is, the plurality of hair material groups 211 are located in the same layer structure. The layering refers to spreading the hair materials of the false eyelashes 10, but the roots of the hair material are still in the same layer structure, and the layering and fluffy effect is only achieved visually.
In addition, for the false eyelashes with a multi-layer structure in Embodiment 2 described later, layering means: the hair materials of the plurality of hair material groups (that is, the first hair material group described later) in each layer structure is spread, and the roots of the hair materials in each layer structure are still in the corresponding same layer, and the layering and fluffy effect is only achieved visually.
Referring to
The difference between Embodiment 2 and Embodiment 1 is that: in Embodiment 2, after being processed, a plurality of false eyelash design patterns need to further be stacked and connected to form one or more false eyelashes with a multi-layer structure.
Referring to
S1000: Provide a substrate.
In Embodiment 2, step S1000 is the same as step S100 in Embodiment 1. Details are not described herein.
S2000: Process a plurality of pre-designed first false eyelashes design patterns 220 on the substrate by a non-heat-applied processing method.
In Embodiment 2, the only difference between step S2000 and step S200 in Embodiment 1 is that: in this step S2000, the plurality of first false eyelashes design patterns 220 need to be pre-designed. In other words, each first false eyelash design pattern 220 cannot be directly sold as a false eyelash after being processed by a non-heat-applied processing method. Therefore, for the parts of step S2000 that are identical to Step S200 in Embodiment 1, details are not described herein.
In this step, as shown in
S3000: Obtain a plurality of first false eyelashes.
In Embodiment 2, the only difference between step S3000 and step S300 in Embodiment 1 is that: in this step S3000, each first false eyelash 40 obtained cannot be directly sold as a false eyelash.
In this step, as shown in
Further, in this step, each first false eyelash 40 includes: a plurality of first hair material groups 41 and a first base 42. It can be seen that the plurality of first hair material groups 41 (eight first hair material groups 41 shown in
Exemplarily, the number of first false eyelashes 40 is not limited in the embodiment of the present application. For example, two, three, four, etc. first false eyelashes 40 can be obtained. As long as the number of first false eyelashes 40 is two or more, it belongs to the protection scope of the embodiment of the present application.
It should be noted that in Embodiment 2 of the present application, after being processed, the plurality of false eyelash design patterns 220 need to be further stacked and connected to form one or more false eyelashes with a multi-layer structure, so the design idea of the design pattern 220 of the false eyelashes is that drawing can be performed based on the fact that the false eyelashes are a multi-layer structure. That is, in the design process of the same batch, the size, shape, and density of the hair material of the plurality of false eyelash design patterns 220 can be the same or different, and the specific selection needs to be made according to the actual effect after stacking.
For example, the first base patterns 222 of the two false eyelash design patterns 220 designed in the same batch are the same, and the first hair material group patterns 221 are the same. Then, after stacking along the thickness direction, the false eyelashes formed have a multi-layer structure, but the visual sense of depth is poor. For another example, the first base patterns 222 of the two false eyelash design patterns 220 designed in the same batch are the same, and the spacing and distribution density of the first hair material group patterns 221 are different. Then, after stacking along the thickness direction, the false eyelashes formed have a multi-layer structure and have a better sense of depth and visual effect. This is not limited in this embodiment of the present application.
S4000: Stack and connect a plurality of first bases of the plurality of first false eyelashes by using ultrasonic welding or a bonding process.
Referring to
In some possible embodiments, this step S4000 may include:
The first bases 42 of at least two first false eyelashes 40 among a plurality of first false eyelashes 40 are stacked.
The first bases 42 of at least two first false eyelashes 40 are fixed by using ultrasonic waves or a bonding material.
That is, at least two first false eyelashes 40 can be stacked in any combination by using ultrasonic welding or a bonding process.
For example, if six first false eyelashes 40 are obtained in the above step S3000, illustratively, the two first bases 42 of two of the first false eyelashes 40 can be stacked in two layers and fixedly connected, the two first bases 42 of another two first false eyelashes 40 can be stacked in two layers and fixedly connected, and the two first bases 42 of the remaining two first false eyelashes 40 can be stacked in two layers and fixedly connected.
Alternatively, the three first bases 42 of three of the first false eyelashes 40 may be stacked in three layers and fixedly connected, and the three first bases 42 of the remaining three first false eyelashes 40 may be stacked in three layers and fixedly connected.
Alternatively, the six first bases 42 of the six first false eyelashes 40 may be stacked in six layers and fixedly connected.
In some possible embodiments, ultrasonic welding is a process of welding plastic or other materials using high-frequency vibration (ultrasonic wave). For example, when ultrasonic waves act on the contact surface of the polyvinyl ethyl ether (PVE) plastic film 111 or other polymer films, high-frequency vibrations of tens of thousands of times per second are generated. By using this high-frequency vibration reaching a certain amplitude, ultrasonic energy is transmitted to the welding area by using an upper weldment. Because the welding area, that is, the interface of the two to-be-welded parts, has a high acoustic resistance, local high temperature is generated.
At the same time, due to the poor thermal conductivity of the polyvinyl ethyl ether (PVE) plastic film 111 or other polymer films, the heat cannot be dissipated in time and is gathered in the welding area, causing the contact surfaces of the two first false eyelashes 40 (that is, the two first bases 42) to melt rapidly. After a certain pressure is applied, the contact surfaces are fused into one. When the ultrasonic waves stop acting, the pressure is maintained for a few seconds to solidify the plastic material in the welding area, thus forming a solid molecular chain to achieve the purpose of welding. The welding strength can be close to the strength of the raw material.
In some possible implementations, in Embodiment 2, the first bases 42 of at least two first false eyelashes 40 can be bonded by using a bonding material.
For example, based on the design of the style and aesthetics of the false eyelashes, the plurality of first false eyelashes 40 can be arbitrarily matched to form different styles. According to different style requirements, a chemical reagent with a bonding function is applied to the first base 42 of the first false eyelash 40 at a position of about 0.1 mm-1 mm. The chemical reagent causes a reaction between the raw material films of a plurality of first bases 42, thereby achieving the effect of bonding the plurality of first false eyelashes 40 together.
For example, the chemical reagent of the embodiment of the present application includes but is not limited to: n-butyl cyanoacrylate (n-Butyl Cyanoacrylate, n-BCA), polyvinyl alcohol (Polyvinyl Alcohol, PVA), etc., which have bonding functions and do not require heat to be applied to the bonding object (that is, the plurality of first false eyelashes 40).
For example, n-butyl cyanoacrylate is a fast-curing adhesive. Due to the fast bonding speed, n-butyl cyanoacrylate is used to bond skin, mucous membranes, plastics, etc. Although n-butyl cyanoacrylate is a cyanoacrylate-based adhesive, it is relatively less irritating, but it needs to be used with caution. For example, polyvinyl alcohol is a water-soluble polymer with good bonding properties and water solubility.
For example, a tape (such as a transparent tape with good adhesion) can be used. The tape is attached to the first base 42 of the first false eyelash 40 at a position of about 0.1 mm-1 mm, and the plurality of first false eyelashes 40 are bonded together to achieve the effect of bonding.
For another example, glue (such as liquid glue with good adhesion) can be used. The glue is applied to the first base 42 of the first false eyelashes 40 at a position of about 0.1 mm to 1 mm, and the plurality of first false eyelashes 40 are bonded together to achieve a bonding effect.
For example, the chemical reagent, the tape, and the glue with bonding functions can also be applied to the connection of traditional polyester fiber eyelash filaments, cotton thread, and fishing line, that is, the chemical reagent, the tape, and the glue with bonding functions are used to bond polyester fiber eyelash filaments, cotton thread, and fishing line to ensure that there is no heating process during the entire process.
It should be noted that the bonding material of the embodiment of the present application refers to a material used for a non-heat-applied processing method, that is, in the process of bonding the first bases 42 using the bonding material, no heat is applied to the first false eyelashes 40.
