Lint-preventing yarn and woven floor decoration material using the same

Abstract

Disclosed are a lint-preventing yarn, which can fundamentally prevent lint formation unlike existing yams, and a woven floor decoration material using same. The lint-preventing yam according to the present invention includes a core layer and a coating layer coated onto the surface of the core layer. The core layer is formed of a plurality of binder-treated fabrics or mono fabrics having a diameter of between 0.1 mm and 5 mm The woven floor decoration material manufactured using same can be free of lint formation when cut into the shape of a tile having a predetermined size or despite friction caused by prolonged use.

1 . Lint-preventing yarns comprising:
 a core layer; and   a coating layer formed on a surface of the core layer,   Wherein the coating layer is composed of a plurality of fibers subjected to binder treatment, or is composed of a mono fiber having a diameter from 0.1 mm to 5 mm.   
     
     
         2 . (canceled) 
     
     
         3 . The lint-preventing yarns according to  claim 1 , wherein the mono fiber is a hollow fiber. 
     
     
         4 . The lint-preventing yarns according to  claim 1 , wherein the plural fibers are dipped into a binder resin comprising at least one of acrylic, methacrylic, polyisoprene, vinyl, epoxy, urethane, and cellulose resins to perform binder treatment. 
     
     
         5 . The lint-preventing yarns according to  claim 1 , wherein the fiber is composed of at least one of PET fibers, glass fibers, and nylon. 
     
     
         6 . The lint-preventing yarns according to  claim 1 , wherein the coating layer formed on the surface of the core layer is formed of a material comprising at least one of polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polyurethane (PU), and thermoplastic polyurethane (TPU). 
     
     
         7 . A woven decorative flooring material comprising:
 a lint-preventing fabric sheet comprising woven fabrics composed of the lint-preventing yarns according to  claim 1 ;   a coating layer formed on an upper side of the fabric sheet; and   a backing layer formed on a lower side of the fabric sheet.   
     
     
         8 . (canceled) 
     
     
         9 . The decorative flooring material according to  claim 6 , further comprising: a dimension stabilizing layer formed between the fabric sheet and the backing layer. 
     
     
         10 . The decorative flooring material according to  claim 6 , wherein the coating layer formed on the upper side of the fabric sheet comprises at least one of urethane and acrylic resins. 
     
     
         11 . The decorative flooring material according to  claim 9 , wherein the dimension stabilizing layer is formed by impregnating glass fibers (G/Fs) into at least one of acrylic, melamine, and PLA resins.
