Embodiments of the inventive concept described herein relate to manufacturing an eco-friendly cup holder by recycling a textile waste, a waste fiber, and a waste plastic, and relate to a method of recycling a textile waste, a waste fiber, and a waste plastic, in which the textile waste, the waste fiber, and the waste plastic are crushed, a non-woven fabric is manufactured, and an eco-friendly cup holder is manufactured based on the manufactured non-woven fabric.
Textile wastes generated in a process of weaving yarn and various chemical fibers and waste fibers remaining after clothing, sewing products, and various textiles are manufactured are specific industrial wastes and thus should be treated carefully. Further, since the industrial wastes such as the textile wastes and the waste fibers are inevitably expensive to treat, unauthorized dumping of waste plastics, textile wastes and waste fibers are frequently performed, and thus serious environmental pollution problems are caused. Thus, a method of recycling these wastes should be explored in various manners.
Currently, a level of recycling the waste plastics, the textile wastes and the waste fibers remains at a level of manufacturing heat insulation covers or resin products. The heat insulation covers are manufactured in the form of a non-woven fabric having a predetermined thickness by compressing the waste plastics, the textile wastes and the waste fibers. Thus, a range of use of the heat insulation cover is not wide, an added value thereof is low, and a lifetime of the heat insulation cover is short. Thus, a limitation that the heat insulation cover is inevitably classified into a specific waste again after the heat insulation cover is used for a certain period of time is pointed out as a fault. Further, the resin product is manufactured by melting the waste plastics, the textile wastes, and the waste fibers, but in this case, there is a serious fault in that costs required for manufacturing the resin product is high and a large amount of air pollutants are generated in the manufacturing process. Thus, there is an urgent need for a utilization method capable of creating a high added value by more efficiently recycling the waste plastics, the textile wastes, and the waste fibers.
Meanwhile, in recent years, many beverages such as coffee become popular. These beverages are not only drunk in stores in which the beverages are sold but are also drunk while users carry disposable cups including the beverages.
However, the disposable cup is used for disposable use and thus is lightweight within a usable range. Thus, the disposable cup is made as thin as possible. Due to characteristics of the disposable cup, heat of contents is easily transferred to the outside, and in the case of a hot beverage, it is difficult for the user to directly grip the disposable cup by his/her hand. Further, in the case of a cold beverage, plastic cups are mainly used. In this case, moisture on an outer surface of the cup, caused by condensation is directly transferred to the hands of the users.
To solve these problems, in general, a cup holder made of a corrugated cardboard is used. However, the corrugated cardboard is unsanitary, is made of wood that is a raw material, and thus causes environmental problems.
In particular, when a cup holder according to the related art made of a paper material is used while mounted on a cup containing a cold beverage, moisture on an outer surface of the cup, which is caused by condensation, is excessively absorbed into the cup holder over time, and thus the cup holder is easily torn even with a small impact and loses a function thereof.
Textile wastes, waste fibers, and waste plastics may be, for example, cotton, rayon, polyester, nylon, polyurethane, wool, or the like. Meanwhile, the amount of waste fibers, which are not reused and discarded, such as the textile wastes, the waste fibers, and pieces of cloth, which are generated during manufacturing in a textile product manufacturing plant, is about 700,000 tons or more per year. As a problem of secondary environmental pollution emerges due to degradation of soil caused by landfilling the waste fibers and generation of toxic gases caused by incinerating the waste fibers, disposal of the waste fibers may become a huge economic and social problem.

An eco-friendly cup holder 100 (see
Referring to
First, the non-woven fabric may be manufactured as follows using the textile wastes, the waste fibers, and the waste plastics (S10).
The textile wastes, the waste fibers, and the waste plastics may be, for example, cotton, rayon, polyester, nylon, polyurethane, wool, or the like. Meanwhile, the amount of waste fibers, which are not reused and discarded, such as the waste plastics, the textile wastes, the waste fibers, and pieces of cloth, which are generated during manufacturing in a textile product manufacturing plant, is about 700,000 tons or more per year. As a problem of secondary environmental pollution emerges due to degradation of soil caused by landfilling the waste fibers and generation of toxic gases caused by incinerating the waste fibers, disposal of the waste fibers may become a huge economic and social problem. In particular, in accordance with the trend of resource-producing countries to weaponize resources along with the measures to ban exports of pollutant products advocated by the World Trade Organizations such as the Rio Environmental Conference, developing alternative materials and alternative products for raw materials is at an important time of environmental preservation and economic development, which are important factors directly related to the life and death of a company.
In detail, the waste plastics, the textile wastes, and the waste fibers are collected and crushed into pieces of 5 cm or less. The crushed pieces are put into a scutcher and are scutched like cotton. When a waste fiber felt is formed by the scutching, the non-woven fabric is manufactured by putting a bonding agent into the waste fiber felt to induce bonding between the pieces of the waste fibers.
Here, the bonding agent may be a natural rubber resin, an epoxy resin, a urea resin, a melamine resin, or an acrylic resin. The bonding agent may be uniformly applied to both surfaces of the waste fiber felt by an amount of, for example, 20 g/m2 to 30 g/m2.
Continuously, the manufactured non-woven fabric is processed into the band-shaped holder member having the one end and the other end through pressing and cutting at a high temperature and a high pressure (S20).
The manufactured non-woven fabric is supplied to a rolling mill, is dried at a high temperature, and is pressed. That is, mechanical properties of the non-woven fabric are improved through a hot pressing process.
In this case, the hot pressing process may be performed in a temperature range of 150° C. to 210° C. Accordingly, the non-woven fabric may be dried so that an impregnation amount of the bonding agent applied to the non-woven fabric in the previous process is 13% or less. Further, during the pressing process, a high pressure applied to the non-woven fabric may be in a range of 0.4 MPa to 1.5 MPa.
During the pressing process, the non-woven fabric may be subjected to a sterilization process. The sterilization process may be performed, for example, through ozone (O3). An ozone treatment method has been described as a method of sterilizing the non-woven fabric, but the method of sterilizing the non-woven fabric is not limited thereto, and sterilization may be performed by a chemical treatment method using a disinfectant.
Meanwhile, during the press process, the non-woven fabric is impregnated with an antibacterial agent so that antibacterial properties of the non-woven fabric and the cup holder manufactured thereby may be improved.
In more detail, during a process of continuously pressing the sterilized non-woven fabric, a process of treating the non-woven fabric with an antibacterial agent is performed. The antibacterial agent may be in the form of a solution dispersed in a solvent. Here, the solvent may be, for example, water, ethanol, methanol, butanol, or isopropyl alcohol.
Meanwhile, the antibacterial agent may be copper oxide, copper sulfide, or 2-Hydroxypropyl-3-Piperazinyl-Quinoline Carboxylic Acid Salt Methacrylate. The antibacterial agent is dispersed in one of the above-described solvents to form an antibacterial agent mixture, the non-woven fabric is impregnated with the antibacterial agent mixture, and thus the non-woven fabric may be treated with the antibacterial agent.
A mixing weight ratio of the antibacterial agent to the solvent in the antibacterial agent mixture may be set to 3:7 to 7:3. When the weight ratio of the solvent is less than three, fluidity of the mixture may be lowered, and application properties of the antibacterial agent may be lowered. Meanwhile, when the weight ratio of the solvent is greater than seven (i.e., when the weight ratio of the antibacterial agent is less than 3), the content of the antibacterial agent in the mixture is lowered, and thus an antibacterial effect of the non-woven fabric may be reduced.
Further, to impart anti-odor properties to the sterilized non-woven fabric, a process of treating the non-woven fabric with an air freshener may be performed. The air freshener may indicate, for example, an apple scent, a grape scent, a limonene scent, a pineapple scent, a strawberry scent, an orange scent, a lemon scent, a rose scent, a lily scent, a pine needle scent, a geranium scent, a cypress scent, a lavender scent, a peppermint scent, a jasmine scent, a gyri scent, a sandalwood scent, a juniper scent, a rosemary scent, a rosewood scent, an eucalyptus scent, a bergamot scent, a lemongrass scent, a tea tree scent, a neroli scent, a vanilla scent, a hazelnut scent, and the like.
The air freshener may be one selected from the group consisting of anethol, benzaldehyde, benzyl acetate, benzyl alcohol, benzyl formate, iso-bornyl acetate, camphene, cis-citral (neral), citronellal, citronellol, citronellyl acetate, para-cymene, decanal, dihydrolinalool, dihydromyrcenol, dimethyl phenyl carbinol, eucalyptol, geranial, geraniol, geranyl acetate, geranyl nitrile, cis-3-hexenyl acetate, hydroxycitronellal, d-Limonene, linalool, linalyl oxide, linalyl acetate, linalyl propionate, methyl anthranilate, alpha-methyl ionene, methyl nonyl acetaldehyde, methyl phenyl carvinyl acetate, raevomenthyl acetate, menthone, iso-Menthone, myrcene, myrsenyl acetate, myrcenol, nerol, neryl acetate, nonyl acetate, phenyl ethyl alcohol, alpha-pinene, beta-pinene, gamma-terpinene, alpha-terpineol, beta-terpineol, terpinyl acetate, vertenex (para-tert-butyl cyclohexyl acetate), amyl cinnamic aldehyde, iso-amyl salicylate, beta-caryophyllene, cedrene, cinnamic alcohol, coumarin, dimethyl benzyl carbinyl acetate, ethyl vanillin, eugenol, iso-eugenol, flor acetate, heliotropin, 3-cis-hexenyl salicylate, hexyl salicylate, lilyal (para-tertbutyl-alpha-methyl hydrocinnamic aldehyde), gamma-methyl ionene, nerolidol, patchouli alcohol, phenyl hexanol, beta-selinene, trichloromethyl phenyl carvinyl acetate, triethyl citrate, vanillin, and veratraldehyde.
In addition, oil may be included as the air freshener. Lavender oil, lavandin oil, lemon oil, or the like may be selected as the air freshener.
Meanwhile, optionally, a deodorizing agent may be further treated. For example, the deodorizing agent may be one selected from the group consisting of carbon fine particles, silica gel, activated alumina, diatomaceous earth, cyclodextrin, and ceramic powder.
Further, in the cup holder according to the embodiment of the inventive concept, when the manufactured non-woven fabric is pressed, a moisture absorbent may be injected and applied onto the surface of the non-woven fabric. For example, silica gel may be selected as the moisture absorbent, but the moisture absorbent is not limited thereto, and any material may be selected as long as the material has a moisture absorption function.
In this way, when the non-woven fabric is manufactured, the moisture absorbent is applied to the surface of the non-woven fabric through a press process, and thus the cup holder according to the embodiment of the inventive concept manufactured from the non-woven fabric may have hygroscopicity. Accordingly, since the cup holder according to the embodiment of the inventive concept has hygroscopicity, when the cup holder is used while mounted on the cup containing a cold beverage, moisture on the outer surface of the cup, which is caused by condensation, is easily absorbed into the cup holder, durability of the cup holder is prevented from being degraded due to the moisture, and thus the cup holder may be prevented from being easily damaged even by a small external impact. Further, the cup holder according to the embodiment of the inventive concept may be dried and reused even after use and has an excellent heat retaining property.
The non-woven fabric pressed at a high temperature/high pressure is cut and processed into the band-shaped holder member having one end and the other end. In the press process, the non-woven fabric is cut and processed into the band-shaped holder member.
Referring to
Continuously, c) the one end and the other end of the holder member 110′ are bonded to each other to form a holder body 110 (see
To form the holder body 110, the one end 11 (see
In more detail, a process of molding the holder member 110′ for forming the holder body 110 is a process of molding the holder body 110 such that the one end 11 and the other end 12 on both sides of the holder member 110′ in an extension direction are coupled to each other to form a ring shape. As the holder body 110 is molded into a hollow cylindrical shape, an accommodation storage in which a cup may be accommodated may be formed.
In this case, a molding frame having a pipe shape may be used to keep a circumference of the holder body 110 constant. Thus, when both sides of the holder member 110′ are coupled to each other in a state in which the holder member 110′ is wound around the molding frame, the holder body 110 having a constant circumference may be formed.
Meanwhile, referring to
A thermoplastic resin may be used as the adhesive. For example, polyester, polyurethane, or the like may be used as the adhesive.
Referring to
Further, referring to
Even when the holder body 110 is formed using the holder member illustrated in
By the above method, the method of manufacturing the eco-friendly cup holder by recycling the textile wastes, the waste fibers, and the waste plastic has been described. Referring to
As illustrated in
The holder body 110 may be formed in a ring shape by coupling both sides of the holder member 110′ having a band having a certain width in an extension direction. That is, when the holder member 110′ is rolled, an adhesive is applied to both sides of the holder member 110′ in contact with each other, and both sides thereof are attached, the holder body 110 having an open upper portion and an open lower portion, that is, having a hollow cylindrical shape, may be formed.
Meanwhile, the holder member 110′ may be formed in a shape unfolded in a fan shape, and accordingly, when both sides thereof in the extension direction are coupled, the accommodation space of the cup having a truncated cone shape having an upper diameter greater than a lower diameter may be formed. A shape of the holder body 110 may be modified into various shapes according to a shape of the cup.
In this way, according to the inventive concept, the cup holder is manufactured from recycled materials, a pattern or an engraved pattern, a printed picture, an image, or the like is added to the surface of the cup holder, and thus a visual effect may be added and an increase in sales may be promoted.
Further, in the cup holder according to the embodiment of the inventive concept, the outer surface of the cup holder exposed to the outside may be laminated with a polyurethane (PU) leather material. Accordingly, the cup holder may provide a sense of artificial leather, also provide a grip sense and a touch sense, and thus resolve a rejection sense of a user.
According to the inventive concept, there are provided manufacturing an eco-friendly cup holder by recycling a textile waste, a waste fiber, and a waste plastic, and a method of recycling a textile waste, a waste fiber, and a waste plastic, in which the textile waste, the waste fiber, and the waste plastic are crushed, a non-woven fabric is manufactured, and an eco-friendly cup holder based on the manufactured non-woven fabric.
Although the embodiments of the inventive concept have been described above, the inventive concept is not limited to the embodiments but may be manufactured in various different shapes, and those skilled in the art to which the inventive concept pertains may understand that the inventive concept may be implemented in other specific forms without changing the technical spirit or essential feature of the inventive concept. Therefore, it should be understood that the embodiments described above are illustrative but not limiting in all aspects.
