Description
The present invention relates to a method for manufacturing a cloth for an environmentally friendly outdoor garment, and more particularly, to a method for manufacturing an environmentally-friendly outdoor garment fabric having a good physical property by a method of saving resources and protecting the environment.
Due to the growing popularity of wellbeing culture in the world and the increasing demand for outdoor activities and outdoor activities, outdoor textile fabrics are becoming popular among consumers as the latest trend in all sports activities and leisure activities , The demand of the market is dramatically increasing. In addition, functionalities in various requirements suitable for outdoor activities are required. Temperature control, lightness, stretchability, ventilation and protection against external environment, UV shielding, breathability Water resistance, windproofness, breathability, and soft touch are also emphasized.
On the other hand, due to global warming caused by environmental pollution, various natural disasters such as various natural disasters are caused, and efforts and international cooperation are actively carried out to regulate or reduce greenhouse gas emissions have.
Since wastes emit a large amount of harmful gas at incineration and the proportion of greenhouse gas emissions is relatively high, it is studied as an alternative to promote the recycling of waste.
However, these conventional regeneration methods have many problems to be solved yet, and they are not effective alternatives because of the following problems.
First, huge equipment and personnel are invested in collection and sorting. In order to maintain the quality of the original product, many people and equipment are put into the collection and sorting of the recovered waste materials, and the business feasibility is often reconsidered due to the high cost problems due to the large amount of impurities in the recovered waste materials.
Another problem is that the quality of the recycled raw material is poor. As described above, although recycling of wastes takes a great deal of money, the purity of raw materials to be regenerated is insufficient, so that they are mixed with new raw materials or used only for low-grade purposes.
Nylon is also widely used for fibers, but it is also used in various industrial applications such as tire cord, fishing rope and film, and its use as a plastic side is also increasing.
In general, nylon products have not been used to regenerate raw materials such as glass or resin products. This is because, in the case of nylon products, it is difficult to dismantle and sort finished products to a level that can be regenerated because of mixing with various other materials. However, industrial fabrics have many materials made from petroleum such as polyester and nylon, and are required to be recycled in terms of resource saving and recycling.
However, it is a fact that there is virtually no environmentally friendly outdoor textile product that extends from raw materials to finished products in the domestic market as well as the global market, which is a rapidly gaining outdoor market.
Korean Patent No. 10-1225158 discloses a method for producing a double knit fabric by using a synthetic fiber such as nylon, polyester, cotton and polyester blend, and then introducing an antimicrobial coating composition into the double knit fabric, And how to improve functionality.
Korean Patent No. 10-1212677 also discloses a method for producing a biodegradable fabric using a polylactic acid yarn as a typical biodegradable material.
However, in the above conventional methods, there has not been attempted a method of recycling the discarded nylon closed net without selecting or disassembling it, and recycling it as a raw material.
Disclosure of the Invention Problems to be Solved by the Invention It is an object of the present invention to provide a method for manufacturing outdoor fabric for outdoor garments, which can save resources and prevent environmental pollution, To provide a method of manufacturing a fabric for an environmentally friendly outdoor garment.
In order to achieve the above object, in the present invention, there is provided a method for producing a nylon filter, comprising the steps of: (i) depolymerizing a nylon closed net that has not been subjected to a disassembling operation or a screening operation, and then mixing thermally conductive inorganic particles with the depolymerized nylon polymer, (Chip); (Ii) a polyester chip (Chip) containing ceramic particles and the above-mentioned regenerated nylon chip (Chip) containing thermally conductive inorganic particles are co-spun together to form a modified cross section, and the core portion is a polyester contained in the ceramic particles The sheath portion is a step of producing a sheath-core type nylon / polyester conjugate fiber made of nylon containing thermally conductive inorganic particles; (Iii) weaving the regenerated fabric using the sheath-core type nylon / polyester conjugate fiber; And (iv) forming a porous layer on the water-repellent layer after forming a water-repellent layer on the recycled surface.
INDUSTRIAL APPLICABILITY The present invention can save resources and prevent environmental pollution by manufacturing fabrics for outdoor garments.
The fabric for outdoor clothing manufactured by the present invention can be used for a variety of applications because it is excellent in processability, dyeability, and moisture-proof and waterproofing properties like a fabric prepared by using a conventional nylon yarn chip as a raw material instead of a nylon reproducing chip Do.
1 is a cross-sectional view of a cis-core type nylon / polyester composite yarn.
Hereinafter, the present invention will be described in detail.
The method for manufacturing an environmentally friendly outdoor garment according to the present invention comprises the steps of: (i) depolymerizing a nylon closed net that has not been subjected to a disassembling operation or a screening operation, and then thermally conductive inorganic particles are mixed with the depolymerized nylon polymer, A step of producing a nylon chip; (Ii) a polyester chip (Chip) containing ceramic particles and the above-mentioned regenerated nylon chip (Chip) containing thermally conductive inorganic particles are co-spun together to form a modified cross section, and the core portion is a polyester contained in the ceramic particles The sheath portion is a step of producing a sheath-core type nylon / polyester conjugate fiber made of nylon containing thermally conductive inorganic particles; (Iii) weaving the regenerated fabric using the sheath-core type nylon / polyester conjugate fiber; And (iv) forming a porous membrane layer on the water-repellent layer after forming a water-repellent layer on the regenerant layer.
Specifically, in the present invention, a nylon closed net that has not undergone a disassembling operation or a screening operation is first depolymerized, and thermally conductive inorganic particles are mixed with the depolymerized nylon polymer to produce a regenerated nylon chip containing thermally conductive inorganic particles.
Next, the polyester chip (Chip) and the regenerated nylon chip (Chip) are co-spun together to have a modified cross-sectional shape. The core portion is a polyester contained in the ceramic particles and the sheath portion is made of nylon containing thermally conductive inorganic particles Core-type nylon / polyester conjugate fiber.
The cis-core type nylon / polyester conjugate fiber is a regenerated fiber having a good cooling function by rapidly generating heat generated in the human body into the atmosphere. The core portion constituting the regenerated fiber is a polyester yarn containing ceramic particles, The regenerated nylon raw material containing thermally conductive inorganic particles plays a role of rapidly dissipating heat generated in the human body into the atmosphere.
The thermally conductive inorganic particles are metal compounds, carbides, oxides, and nanocomposites having higher thermal conductivity than TiO 2 .
The total fineness of the sheath-core type nylon / polyester conjugate fiber is preferably 10 to 50 denier in the production of a fabric for clothing.
1 is a schematic cross-sectional view of the sheath-core type nylon / polyester conjugate fiber.
Next, the regenerated fabric is woven using the sheath-core type nylon / polyester conjugate fiber.
When the cloth for eco-friendly outdoor clothes is woven using the sheath-core type nylon / polyester conjugate fiber, the regenerated nylon multifilament may be used only for the warp yarn, only for the warp yarn, or for both warp and weft yarns.
Next, a water-repellent layer is formed on the regenerated fabric, and then a porous membrane layer is formed thereon to produce a fabric for an environmentally-friendly outdoor garment of the present invention.
As an example of implementation, a reclaimed fabric is dipped in a non-fluorinated water repellent and dried to form a water repellent layer on the regenerated fabric, then the one-part polyurethane resin composition (including solvent) is coated on the water repellent layer, And dried to form a porous membrane.
Since the nylon closed net of the present invention is reproduced to fabricate the cloth for the environment friendly outdoor clothing, the resources can be saved and the environmental pollution can be minimized.
Further, the present invention simplifies the process because the nylon closed network is demarcated as it is without disassembly operation or selection operation.
In addition, the fabric for environmentally-friendly outdoor garment manufactured by the present invention is excellent in dyeability and physical properties and can be applied to various applications.
Hereinafter, the present invention will be described in more detail with reference to examples and comparative examples.
