Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing an eco-friendly lightweight textile,

The present invention relates to a process for producing an environmentally friendly lightweight textile. More particularly, the present invention relates to a process for producing an environmentally friendly, lightweight, lightweight and / or moisture- And a method of manufacturing a textile.

Hereinafter, the "environmentally lightweight textile" used in the present invention is made up of (i) a lightweight fabric 1 of a one-layer structure as shown in FIG. 1 or (ii) Layer structure of a two-layer structure (T1) laminated with an environmentally friendly thermoplastic resin membrane 2 on the surface thereof or (iii) an environmentally friendly thermoplastic resin membrane 2 on the back surface of the lightweight fabric 1 Layered structure T2 in which the fabric blank paper 3 is laminated on one side of the environmentally friendly thermoplastic resin membrane 2 that is not in contact with the lightweight fabric 1 on both sides thereof.

In recent years, interest in the well-being culture has been increasing worldwide, so that the fashionability and fashionability to be provided by conventional clothing products have been improved. In addition to this, the environmentally friendly, harmless, and lightweight There is a growing demand for environmentally friendly lightweight textiles, including waterproofness, moisture permeability, and the like.

Korean Patent Registration No. 10-1482874 (patent pending: Daicek Research Institute) discloses a conventional technique for producing a lightweight textile, in which a microporous film mainly composed of a polyurethane resin is laminated on a surface of an ultra light nylon fabric by a hot melt laminating process, A lightweight nylon fabric having a coating film was prepared.

The ultra lightweight nylon fabric manufactured by the above-mentioned prior art is excellent in moisture permeation and waterproofing property, but since the microporous film is manufactured using a solvent (sol belt), the environment is contaminated during manufacturing and harmful to human body, .

Another conventional technique for producing lightweight textiles is disclosed in Korean Patent Laid-open Publication No. 10-2015-0002078 (filed by Newmantex Styles Co., Ltd. / Korea Textile Development Institute), which is a first synthetic fiber produced by mixing nylon 6 yarn and polyester yarn A method for fabricating an ultra lightweight sheet excellent in melange effect by dyeing a second horny yarn produced by mixing a nylon 66 yarn and a polyester yarn respectively and weaving the fabric using these as warp and weft yarns.

However, the ultralight thin sheet produced by the conventional method has an excellent melange effect, but since it does not use an eco-friendly blue dye in dyeing, it is not suitable as an eco-friendly material because the environment is contaminated during production.

As a further conventional technique for producing lightweight textiles, Korean Patent Registration No. 10-1244963 (patentee: WL Gore & Associates, Germany) discloses a method for producing a lightweight textile, comprising: (i) using a spun yarn as warp and weft, A method of producing a lightweight fabric in which a fabric having a weight of 20 to 500 g / m 2 is woven and then a void of the woven fabric is filled with a polymer material such as silicone, and (ii) Or a moisture barrier layer composed of a barrier layer are laminated on a substrate.

However, the above-mentioned conventional method has a problem in that the process is complicated because the pores of the lightweight fabric are filled with a polymer material such as silicone or the like and the solvent (solvent) is used in the production of the barrier layer.

On the other hand, Korean Patent Registration No. 10-1466328 (patentee: Gollim Fiber Textile Co., Ltd.), as a conventional technique for manufacturing a low-density paper beaker (corresponding to a thin paper fabric constituting a fabric white paper in the present invention) Inch filament or nylon filament having a filament count of 15 to 15 denier and having a warp tension of 90 to 15 yarns / inch and a weft density of 70 to 120 yarns / inch under an oblique tension of 1 to 5 N / m, Becker is showing how to weave.

However, since the conventional method has a low warp and weft density, there is a problem in that warp and weft yarns constituting the fabric occur in a post-process such as dyeing after weaving, resulting in poor quality. In addition, The conditions and the water-repellent conditions were not specifically addressed.

As another conventional technique for manufacturing a woven fabric (corresponding to a knitted fabric constituting a fabric blank in the present invention), Korean Patent Laid-Open Publication No. 1998-0008085 (filed by K.D. Tex.) Discloses a method in which a polyester yarn is knitted A method of producing a woven fabric by dyeing and processing the produced woven fabric, applying an adhesive to the stained / stiffened woven fabric, and then heating and quenching the woven fabric. However, since the core woven fabric manufactured by the conventional method is knitted, the woven fabric is easily deformed and does not support the outer appearance of the outer surface properly, and when the adhesive is applied to the woven fabric, it is not suitable as an eco-friendly material.

Korean Patent Laid-Open No. 10-2004-0103838 (filed by Sungbo Industries Co., Ltd.) discloses a method of weaving lining fabrics through a weaving process after a warp, weaving, .

At this time, polyester warp yarn of 30 to 100 denier was mainly used for warp and weft yarn. However, the lining fabric prepared by the conventional method has a single yarn fineness of 30-100 denier and is small in stretchability to stably support the outer fabric, but the fabric is thick and has a high weight, which is not suitable as a lightweight fabric.

A problem to be solved by the present invention is to provide an eco-friendly lightweight textile which is eco-friendly, lightweight and excellent in moisture permeability and waterproofness because it does not use solvents (solvents), water repellents and dyes harmful to the environment or human body during the manufacturing process.
