Abstract

A heat-generating fabric contains an modacrylic fiber A and an animal hair fiber. The modacrylic fiber A contains an infrared absorber inside of the fiber, in an amount of 1 to 30% by weight with respect to the total weight of the modacrylic fiber, and the fabric has a heat-shielding rate of less than 40% as measured according to JIS L 1951:2019. The heat-generating fabric contains a first yarn and a second yarn whose fiber composition is different from that of the first yarn. The first yarn may contain the modacrylic fiber A, and the second yarn may contain the animal hair fiber. Accordingly, it is possible to provide a fabric with good heat-generating performance and durability, and a textile product containing the fabric.

Claims

exact text as granted — not AI-modified
1 . A heat-generating fabric comprising an modacrylic fiber A and an animal hair fiber, wherein:
 the modacrylic fiber A comprises an acrylic polymer comprising 40 to 70% by weight of acrylonitrile,   the modacrylic fiber A comprises an infrared absorber inside the fiber, in an amount of 1 to 30% by weight with respect to a total weight of the modacrylic fiber, and   the fabric has a heat-shielding rate of less than 40% as measured according to JIS L 1951:2019.   
     
     
         2 . The heat-generating fabric according to  claim 1 , comprising 0.5 to 20% by weight of the infrared absorber with respect to a total weight of the heat-generating fabric. 
     
     
         3 . The heat-generating fabric according to  claim 1 , wherein the modacrylic fiber A further comprises an antimony compound inside the fiber. 
     
     
         4 . The heat-generating fabric according to  claim 3 , wherein the modacrylic fiber A comprises 2 to 30% by weight of the antimony compound with respect to a total weight of the modacrylic fiber A. 
     
     
         5 . The heat-generating fabric according to  claim 3 , wherein the antimony compound comprises one or more selected from the group consisting of antimony trioxide, antimony tetroxide, and antimony pentoxide. 
     
     
         6 . The heat-generating fabric according to  claim 1 , wherein the animal hair fiber is wool. 
     
     
         7 . The heat-generating fabric according to  claim 1 , comprising 30 to 70% by weight of the modacrylic fiber A and 30 to 70% by weight of the animal hair fiber with respect to a total weight of the heat-generating fabric. 
     
     
         8 . The heat-generating fabric according to  claim 1 , comprising a first yarn and a second yarn whose fiber composition is different from that of the first yarn,
 wherein the first yarn comprises the modacrylic fiber A, and the second yarn comprises the animal hair fiber.   
     
     
         9 . The heat-generating fabric according to  claim 1 , wherein the infrared absorber is a tin oxide-based compound. 
     
     
         10 . The heat-generating fabric according to  claim 1 , having a fabric weight of 100 to 350 g/m 2 . 
     
     
         11 . A textile product comprising the heat-generating fabric according to  claim 1 . 
     
     
         12 . The textile product according to  claim 11 , wherein the heat-generating fabric comprises 0.5 to 20% by weight of the infrared absorber with respect to a total weight of the heat-generating fabric. 
     
     
         13 . The textile product according to  claim 11 , wherein the modacrylic fiber A further comprises an antimony compound inside the fiber. 
     
     
         14 . The textile product according to  claim 13 , wherein the modacrylic fiber A comprises 2 to 30% by weight of the antimony compound with respect to a total weight of the modacrylic fiber A. 
     
     
         15 . The textile product according to  claim 13 , wherein the antimony compound comprises one or more selected from the group consisting of antimony trioxide, antimony tetroxide, and antimony pentoxide. 
     
     
         16 . The textile product according to  claim 11 , wherein the animal hair fiber is wool. 
     
     
         17 . The textile product according to  claim 11 , wherein the heat-generating fabric comprises 30 to 70% by weight of the modacrylic fiber A and 30 to 70% by weight of the animal hair fiber with respect to a total weight of the heat-generating fabric. 
     
     
         18 . The textile product according to  claim 11 ,
 wherein the heat-generating fabric comprises a first yarn and a second yarn whose fiber composition is different from that of the first yarn, and   wherein the first yarn comprises the modacrylic fiber A, and the second yarn comprises the animal hair fiber.   
     
     
         19 . The textile product according to  claim 11 , wherein the infrared absorber is a tin oxide-based compound. 
     
     
         20 . The textile product according to  claim 11 , wherein the heat-generating fabric has a fabric weight of 100 to 350 g/m 2 .
