This application is based upon and claims foreign priority to Chinese Patent Application No. 202220788114.7, filed on Apr. 7, 2022, the entire content of which is incorporated herein by reference.
The present disclosure relates to the field of curtains, and in particular to a vertical light-adjustable fabric and gauze integrated curtain.
A fabric and gauze integrated curtain is a curtain that consumers are looking forward to. For thin gauzes, the thinner the better, the finer the better. For thick fabrics, the thicker the better, the more soundproof the better, and the more lightproof the better. At present, fabric and gauze integrated curtains on the market are produced by a professional warp knitting machine. Since the fabric structure includes both fabrics and gauzes, thin and thick parts are woven integrally, the warp and weft densities of the gauzes and fabrics are mutually constrained, and there are several defects: (1) There are not many device options, there are relatively large limitations on the selection of machines, and thick parts of fabrics require a large number of guide bars of machines. (2) Material requirements are limited: there are more limitations on the selection of yarns, too thick yarns are difficult to weave, and too thin yarns have insufficient thicknesses. (3) The efficiency and the production capacity are not high, the production speed of a machine is determined by use of the machine, the production efficiency of weaving thin parts uniformly or weaving thick parts uniformly is very high, but the production efficiency of weaving thin and thick parts integrally is greatly reduced. (4) There are high requirements for machines and workers: since there are thick and thin parts, from the perspective of use, it is necessary to make the thin parts as thin as possible and make the thick parts as thick as possible, but there are high requirements for devices and high requirements for spinners. (5) The quality of products is difficult to control: thin parts are too thin, thick parts are too thick, it is easy to cause thread breakage, yarn breakage and needle breakage in synchronous production processes of thin and thick parts, once the yarn breakage or needle breakage occurs, it is necessary to stop the machine, and once the machine is stopped, stop marks will appear on the fabric, so the quality is difficult to control. (6) The light-shading and sun-shading properties are poor: due to the structural nature of the product, 10-50 cm of one unit forms a cycle, and the entire fabric is composed of 3-6 units. When the product is applied, the units need to be disassembled one by one, that is, the width is 10-50 cm. During stripping, there should be neither loose yarns nor excessive thread ends. At present, the most ideal technology on the market is the warp knitting technology. However, the warp knitting technology has the defects of deficient density and poor sun-shading and light-shading properties, and the sun-shading and light-shading effects of the warp knitting technology are inferior to the sun-shading and light-shading effects of the shuttle weaving technology. Due to the structural requirements of the product, it is necessary to apply a coating of the fabric for the thick part to compensate for the defect of poor sun-shading and light-shading properties, but the actual operation process is not easy. The boundary between the (fabric) thick part and the (gauze) thin part is difficult to handle during processing. (7) Post-processing procedures are complicated: since the product structure is composed of several small units of fabrics and gauzes, during shaping, it is necessary to well control the balance point of shrinkage between fabrics (thick parts) and gauzes (thin parts).
At present, the shaping process procedure of this product is as follows: (1) blank shaping: the temperature of a shaping machine is adjusted to 200-220° C., and the vehicle speed is adjusted to 15-20 km/h; (2) dyeing: the dyeing procedure takes 20 min longer than the normal procedure; (3) drying: the shaping temperature is adjusted to 200-220° C., and the vehicle speed is adjusted to 20-30 km/h; and (4) shaping: assistants are added, the temperature of the shaping machine is adjusted to 200-220° C., and the vehicle speed is adjusted to 15-22 km/h. Due to the specificity of the product structure and the specificity of free suspension use of the product, the requirements for the shaped product are extremely high. An error of free fall of six meters should not exceed ±1 cm, and the balance point of shrinkage between the two should be well controlled. After multiple times of oven baking, the verticality of the product is a challenge and is very difficult to control. The temperature, weft skew, vehicle speed, strain and warp and weft tension also have a very high sensitivity requirement for the shaping machine.
The patent for the present disclosure with the Chinese patent number 201621430228.5 discloses a light-adjustable dual-purpose curtain fabric, including two layers of curtain fabric bodies arranged side by side. The curtain fabric body is formed by light-pervious mesh fabric sheets and light-tight cloth fabric sheets. The mesh fabric sheets and the cloth fabric sheets are sequentially arranged at intervals in a multi-sheet form in a vertical direction of the curtain fabric body. Each mesh fabric sheet and each cloth fabric sheet are connected end to end to form a one-fabric one-mesh structure. The back side of the cloth fabric sheet is woven with individual wefts in which threads can pass through. In the patent for the present disclosure, by pulling a curtain head and back threads of the cloth fabric sheets, one fabric is made into two products with two expression forms. Moreover, the purpose of adjusting light is achieved by adjusting the positions of the light-tight cloth fabric sheets and the light-pervious mesh fabric sheets. The structure is simple, and the practicality is strong.
The technical problem to be solved by the present disclosure is to overcome existing technical defects and provide a vertical light-adjustable fabric and gauze integrated curtain. After the structural upgrade, the product can be sewn, glued or welded. The gauze (thin) part is not constrained by the thicknesses of warps and wefts, and the gauze can be freely switched to various specifications on the market. According to the upgrade of the process, there are following advantages: (1) The production capacity is high: devices on the market for single production of thin gauzes can basically reach 800-2000 revolutions, so compared to 400-600 revolutions of previous professional devices, the production capacity is two to three times higher. (2) The devices on the market are quite mature, the efficiency is high, the defective percentage is also very low, the requirements for workers are general, and one spinner can operate 3-5 devices, which is more than twice as much as before when one person can only operate 1-2 devices. (3) The selectivity of yarn products is high, for example, gauzes with various structural mechanisms can be woven according to various densities, patterns and yarn raw materials. (4) The shaping process is simple, and the speed can reach 30-100 km/h, which is several times more efficient than before. (5) Fabric (thick) parts can be subjected to knitting, shuttle weaving, combination and coating, yarns with different thicknesses can be changed freely, the density is easy to control, and fabrics with any density and thickness can be woven according to the thicknesses of yarns to achieve better sun-shading and soundproof effects. In short, the patent for the present disclosure solves a series of problems caused by the mutual restriction between thin parts of gauzes and thick parts of fabrics, such as dyeing and finishing shrinkage, perspective effect, light-shading and sun-shading effects vertical shaping effect and the like. Moreover, the energy consumption of post-processing dyeing and finishing is reduced. Based on an annual output of 2000 tons, the same product can reduce natural gas by 576800 m3, electricity by 1080000 kWh, and steam by 1200 m3.
In view of the defects of low weaving and shaping efficiency, low curtain verticality, poor light-shading and sun-shading properties, and the like of fabric and gauze integrated curtains in the prior art, the present disclosure provides a vertical light-adjustable fabric and gauze integrated curtain.
The present disclosure solves the above technical problems through the following technical solutions:
A vertical light-adjustable fabric and gauze integrated curtain includes light-shading portions and light-pervious portions alternately arranged vertically. The light-pervious portion is a light-pervious thin gauze. The light-shading portion is composed of an upper-layer fabric, a middle-layer thin gauze and a lower-layer fabric. The middle-layer thin gauze is a thin gauze integrated with the light-pervious portion. The upper-layer fabric and the lower-layer fabric are one-piece light-tight fabrics. The upper-layer fabric and the lower-layer fabric are coated on upper and lower surfaces of the middle-layer thin gauze to form the light-shading portion. The basic shape of the curtain is a vertical louver formed by alternating layers of fabrics and gauzes. Users can customize curtains with different widths according to the sizes of windows. The width of the one-piece light-tight fabric is twice the width of the gauze of the light-pervious portion, so the upper and lower surfaces of the gauze are exactly covered. At this time, the light-shading portion forms a structure with a layer of gauze sandwiched between the upper and lower fabrics, and a width of the light-shading portion is equal to a width of the light-pervious portion. In this case, the fabric is individually woven and shaped, the gauze is individually woven and shaped, and then, the fabric and the gauze are combined to form a fabric and gauze integrated curtain, thereby overcoming various defects caused by traditional integrated weaving of fabrics and yarns.
Preferably, two light-shading portions and one light-pervious portion form one unit, the width of each unit is 10-50 cm, and the curtain is composed of 3-6 units. Users can customize curtains with different widths according to the sizes of windows.
Preferably, a mode of coating the upper-layer fabric and the lower-layer fabric with the thin gauze is heat sealing, gluing or sewing. Different fixing modes have respective advantages and disadvantages. Different fixing modes can be selected according to the needs of users. The fabric and the gauze are stably fixed and not easy to loosen.
Preferably, the width of the light-shading portion is greater than or equal to the width of the light-pervious portion. The light-shading portion is a light-shading fabric capable of covering articles to avoid contact with strong light. The light-pervious portion is a light-pervious fabric capable of allowing irradiation of light. Users can adjust the vertical angle between the light-shading portion and the light-pervious portion to achieve different light-shading needs.
Preferably, the middle-layer thin gauze of the light-shading portion and the thin gauze of the light-pervious portion are integrally formed, and the upper-layer fabric and the lower-layer fabric are integrally formed. The integrally formed fabric is coated on an outer surface of the gauze, thereby avoiding the defects of occurrence of joints and unstable coating caused by coating of two layers of individual fabrics.
Preferably, the curtain can be vertically rotated to adjust light. When the light-pervious portion is rotated to a position vertical to the light-shading portion, the curtain is in a light-shading state as a whole. When the light-shading portion is rotated to a position vertical to the light-pervious portion, the curtain is in a light-pervious state as a whole. When the light-shading portion and the light-pervious portion are both horizontal, the curtain is in a semi-light-pervious state as a whole. When the light-shading portion and the light-pervious portion are rotated to a certain angle, the curtain presents different degrees of light-shading states. Users can adjust the light-shading state of the curtain by adjusting any angle between the light-shading portion and the light-pervious portion according to actual needs.
Preferably, the gauze and the fabric are individually woven and shaped before being coated. The efficiency of individual weaving and shaping is high, and the selection range of yarns is wider, thereby overcoming the defects of easy thread breakage, yarn breakage and needle breakage in synchronous production processes of thin and thick parts.
Preferably, after the gauze and the fabric are shaped, an error of free fall of six meters is less than or equal to 1 cm. This fabric and gauze integrated curtain requires higher verticality to achieve the effect of free vertical rotation, so traditional fabric and gauze integrated weaving cannot meet the requirement of the target verticality.
Preferably, the gauze and the fabric can be woven from yarns with different thicknesses by different devices to finally obtain gauzes and fabrics with different densities, different thicknesses and different patterns. Fabrics and gauzes are individually woven, which does not involve the boundary between thick and thin joints of fabrics and gauzes, and the balance point of shrinkage between fabrics (thick parts) and gauzes (thin parts) can be well controlled, thereby greatly improving the quality and manufacturing efficiency of the curtain.
Due to the adoption of the above technical solutions, the present disclosure has the following significant technical effects:
The names of the parts indicated by numerical labels in the accompanying drawings are as follows:
The present disclosure is further described in detail below with reference to the accompanying drawings and embodiments.
As shown in
The basic shape of the curtain is a vertical louver formed by alternating layers of fabrics and gauzes. Users can customize curtains with different widths according to the sizes of windows. The width of the one-piece light-tight fabric is twice the width of the gauze of the light-pervious portion, so the upper and lower surfaces of the gauze are exactly covered. At this time, the light-shading portion forms a structure with a layer of gauze sandwiched between the upper and lower fabrics, and the width of the light-shading portion is equal to the width of the light-pervious portion. In this case, the fabric is individually woven and shaped, the gauze is individually woven and shaped, and then, the fabric and the gauze are combined to form a fabric and gauze integrated curtain, thereby overcoming various defects caused by traditional integrated weaving of fabrics and yarns.
The curtain can be vertically rotated to adjust light. When the light-pervious portion is rotated to a position vertical to the light-shading portion, the curtain is in a light-shading state as a whole. When the light-shading portion is rotated to a position vertical to the light-pervious portion, the curtain is in a light-pervious state as a whole. When the light-shading portion and the light-pervious portion are both horizontal, the curtain is in a semi-light-pervious state as a whole. When the light-shading portion and the light-pervious portion are rotated to a certain angle, the curtain presents different degrees of light-shading states. Users can adjust the light-shading state of the curtain by adjusting any angle between the light-shading portion and the light-pervious portion according to actual needs.
The fabrics and gauzes of the fabric and gauze integrated curtain of the present disclosure are individually woven and shaped, the fabrics and gauzes are not constrained by the thicknesses of warps and wefts, the fabric verticality is higher, and the defects of easy thread breakage, yarn breakage and needle breakage in synchronous production processes of thin and thick parts are overcome. The gauze and the fabric can be woven from yarns with different thicknesses by different devices to finally obtain gauzes and fabrics with different densities, different thicknesses and different patterns. The weaving and shaping processes are simple, the production efficiency of machines is high, the production capacity is high, and the energy consumption is low. The balance point of shrinkage between fabrics and gauzes can be well controlled, so the light-shading and light-pervious effects of the curtain are good.
