Abstract

The present invention relates to a conjugate fiber with moisture-absorbed elongation characterized by comprising a polyamide-containing component and a polyolefin-containing component. The conjugate fiber consists of the configuration of sun-moon side-by-side type or the configuration of eccentric core-sheath type. The conjugate fiber according to the present invention has a moisture-absorbed elongation effect. The length of the conjugate fiber increases by water-absorbing or moisture-absorbing, and the fiber recovers to original length after moisture-releasing.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A conjugate fiber with moisture-absorbed elongation characterized by comprising a polyamide component and a polyolefin component, which is consisted of a configuration of sun-moon side-by-side type or a configuration of eccentric core-sheath type; the conjugate fiber has a moisture-absorbed elongation effect, and the length of the conjugate fiber increases by water-absorbing or moisture-absorbing, and the fiber recovers to original length after moisture-releasing. 
     
     
         2 . The conjugate fiber with moisture-absorbed elongation according to  claim 1 , in which the polyamide component is nylon 6 or nylon 66. 
     
     
         3 . The conjugate fiber with moisture-absorbed elongation according to  claim 1 , in which the polyolefin component is polyethylene, polypropylene and the copolymer thereof or a blend of which with polyester or polyamide. 
     
     
         4 . The conjugate fiber with moisture-absorbed elongation according to  claim 1 , in which the cross-section thereof is a configuration of sun-moon side-by-side type or a configuration of eccentric core-sheath. 
     
     
         5 . The conjugate fiber with moisture-absorbed elongation according to  claim 1 , which is high oriented yarn (HOY), spin drawn yarn (SDY) or draw texture yarn (DTY). 
     
     
         6 . A yarn comprising the conjugate fiber with moisture-absorbed elongation according to  claim 1 .
