Pile fabric

Abstract

It is aimed to provide a pile fabric that is favorable in anticurling and pile-raising performance and in curbing of coming off of the piles. To this end, yarns forming the ground part are core-in-sheath yarns having sheaths of low-melting resin; knitting or weaving pattern is such that the piles are raised or erected when the fabric is strained to stretch in either of warp and weft directions; and the piles are fixed in an erect state, on the ground part, as a result of heat setting at a time the fabric is strained in the warp or weft direction. The fabric has been subjected to the heat setting at a temperature not lower than a melting temperature of the low melting resin; and a change in average pile-raising extent of the fabric is not less than 2%, before and after the heat setting.

1 . A pile fabric which is comprised of piles and a ground part; wherein yarns forming the ground part are formed of core-in-sheath yarns having sheaths comprised of low-melting resin; knitting or weaving pattern is such that the piles are raised or erected when the fabric is strained to stretch in either of warp and weft directions; and the piles are fixed in an erect state, on the ground part, as a result of heat setting at a time the fabric is strained to stretch in either of warp and weft directions. 
   
   
       2 . The pile fabric according to  claim 1 , wherein the fabric has been subjected to the heat setting at a temperature not lower than a melting temperature of the low melting resin; and a change in average pile-raising extent of the fabric is not less than 2%, before and after the heat setting. 
   
   
       3 . The pile fabric according to  claim 1  or  2 , wherein yarns of the ground part are bonded with other ones by fusing. 
   
   
       4 . The pile fabric according to  claim 1  or  2 , wherein the fabric is a tricot knitted fabric. 
   
   
       5 . The pile fabric according to  claim 1  or  2 , wherein the fabric is raised. 
   
   
       6 . A manufacturing method of a pile fabric, which is comprised of piles and a ground part, comprising: adopting yarns forming the ground part, which are formed of core-in-sheath yarns having sheaths comprised of low-melting point resin; knitting or weaving of the pile fabric in such a pattern that the piles are raised or erected when the fabric is strained to stretch in either of warp and weft directions; and heat-setting of thus knitted or woven fabric at a time the knitted or woven fabric is strained to stretch in said either of warp and weft directions, at a temperature not less than a melting point of the low-melting resin.
