Description

Cellulose fiber-based coated fabric and method for manufacturing the same

[0001] The present invention relates to a cellulose fiber-based coated fabric and a method for manufacturing the same, and more specifically, to a cellulose fiber-based coated fabric that is not only environmentally friendly because it does not contain any harmful substances, but also has excellent stain resistance, color fastness, pilling, snagging, elongation recovery, and burst strength, and has a low drape coefficient, and a method for manufacturing the same.

[0002]

[0003] Traditionally, general textile fashion materials and fabrics were manufactured using only natural fibers extracted from cotton or animals, but recently, with the development of the textile chemical industry, synthetic fibers such as polyester, polyamide, acrylic, and polyurethane are being manufactured as main raw materials to improve mechanical properties and water resistance.

[0004] Products manufactured using the synthetic fibers listed above as their main raw materials have many advantages in terms of durability and physical properties as textile fashion materials, but they are difficult to decompose naturally after use, so they are disposed of through incineration or landfill. Incineration releases hazardous substances that are a burden to the human body and the environment, and landfilling places a significant burden on the soil environment as it takes hundreds of years for them to biodegrade.

[0005] Meanwhile, recently, in order to improve the functionality and aesthetics of textile fashion products, textile products such as CvC (Chief value Cotton) or CvS (Chief value Synthetic) yarn and fabric are being manufactured using polyester, a common synthetic fiber, and natural cotton fiber as main raw materials. The above synthetic fibers are products manufactured using polyester as the main raw material and have various advantages in durability and physical properties as textile fashion materials, but they are difficult to dispose of after use, take too long to biodegrade when buried, and in case of incineration, there were problems in that harmful gases were emitted that are a burden to the human body and the environment.

[0006]

[0007] The present invention has been devised in consideration of the above points, and the purpose of the present invention is to provide a cellulose fiber-based coated fabric and a method for manufacturing the same, which is not only environmentally friendly because it does not contain harmful substances, but also has excellent stain resistance, color fastness, pilling, snagging, elongation recovery, and burst strength, and has a low drape coefficient.
