Fiber structure

Abstract

In order to provide a fiber structure having excellent heat retention and wearing comfort and a garment obtained by using the same, there is provided a fiber structure containing: a viscose rayon fiber in an amount of more than 15% by mass and less than 40% by mass; a cation dyeable polyester filament yarn in an amount of more than 10% by mass and less than 45% by mass; a polyacrylic synthetic fiber in an amount of more than 25% by mass and less than 60% by mass; and a spandex fiber in an amount of more than 3% by mass and less than 15% by mass, wherein the fiber structure has a nap formed on a front surface or a back surface thereof.

1 . A fiber structure comprising:
 a viscose rayon fiber in an amount of more than 15% by mass and less than 40% by mass;   a cation dyeable polyester filament yarn in an amount of more than 10% by mass and less than 45% by mass;   a polyacrylic synthetic fiber in an amount of more than 25% by mass and less than 60% by mass; and   a spandex fiber in an amount of more than 3% by mass and less than 15% by mass, wherein   the fiber structure has a nap formed on a front surface or a back surface thereof.   
     
     
         2 . The fiber structure according to  claim 1 , wherein the fiber structure is formed of a knitted fabric having a two-layer structure. 
     
     
         3 . The fiber structure according to  claim 1 , wherein a single fiber fineness of the cation dyeable polyester filament yarn is 0.6 dtex or more. 
     
     
         4 . The fiber structure according to  claim 1 , wherein a heat retention rate of the fiber structure is 20% or more. 
     
     
         5 . The fiber structure according to  claim 1 , wherein a hygroscopic heat generation of the fiber structure is 2.2° C. or more. 
     
     
         6 . The fiber structure according to  claim 1 , wherein a fluff adhesion of the surface of the fiber structure having the nap is 4.0 grade or more. 
     
     
         7 . The fiber structure according to  claim 1 , wherein a stretch recovery percentage of the fiber structure is 80% or more. 
     
     
         8 . A garment obtained by using the fiber structure according to  claim 1 .
