Nylon Composite Fiber and Fabric Thereof

Abstract

A nylon composite fiber and a nylon fabric thereof are provided. This nylon composite fiber is a dual-component fiber, and contains a long chain polyamide and a polyether modified polyamide polyamide. One monomer of the long chain polyamide contains a long aliphatic chain. One monomer of the polyether modified polyamide contains a polyether chain.

         1 . A nylon composite fiber, comprising:
 a first nylon fiber containing a long chain polyamide polymerized by a straight-chain aliphatic diamine having m carbons and a first straight-chain aliphatic diacid having n carbons, wherein (n-2) is an integral multiple of (m-2), and one of m and n is at least 10; and   a second nylon fiber containing a polyether modified polyamide co-polymerized by a lactam, a polyether diamine and a second straight-chain aliphatic diacid, wherein the lactam has 4-12 carbons, the polyether diamine has 2-6 carbons between adjacent two oxygen atoms, and the second straight-chain aliphatic diacid has 6-12 carbons,   wherein the nylon composite fiber is a side-by-side composite fiber or an eccentric core-sheath fiber.   
     
     
         2 . The nylon composite fiber of  claim 1 , wherein the long chain polyamide is nylon 6.10, nylon 6.14, or nylon 10.10. 
     
     
         3 . The nylon composite fiber of  claim 1 , wherein an added amount of the polyether diamine in added monomers of the polyether modified polyamide is 3-20 wt %. 
     
     
         4 . The nylon composite fiber of  claim 1 , wherein the average molecular weight of the polyether diamine is about 400-5000. 
     
     
         5 . The nylon composite fiber of  claim 1 , wherein the polyether diamine is polyethyleneoxy diamine, polybutyleneoxy diamine, or polyhexyleneoxy diamine. 
     
     
         6 . The nylon composite fiber of  claim 1 , wherein the nylon composite fiber is a helical fiber. 
     
     
         7 . A fabric comprising the nylon composite fiber of  claim 1 . 
     
     
         8 . The fabric of  claim 7 , wherein the long chain polyamide is nylon 6.10, nylon 6.14, or nylon 10.10. 
     
     
         9 . The fabric of  claim 7 , wherein an added content of the polyether diamine in added monomers of the polyether modified polyamide is 3-20 wt %. 
     
     
         10 . The fabric of  claim 7 , wherein the average molecular weight of the polyether diamine is about 400-5000. 
     
     
         11 . The fabric of  claim 7 , wherein the polyether diamine is polyethyleneoxy diamine, polybutyleneoxy diamine, or polyhexyleneoxy diamine. 
     
     
         12 . The fabric of  claim 7 , wherein the nylon composite fiber is a helical fiber when the nylon composite fiber is a side-by-side composite fiber. 
     
     
         13 . A fabric comprising a nylon composite fiber, wherein the nylon composite fiber comprises:
 a first nylon fiber made from nylon 6.10;   a second nylon fiber made from a polyether modified polyamide co-polymerized by caprolactam, a polyether diamine, and adipic acid, wherein the polyether diamine is polyethyleneoxy diamine, or polybutyleneoxy diamine.
