Abstract

The present invention provides a fabric that is less likely to generate crackling static electricity when worn, less likely to get wrinkled after being washed, and has highly durable warmth retention and wear comfortability, and a garment manufactured using the same. The fabric of the present invention is a fabric comprising a viscose rayon fiber in an amount of more than 30% by weight and less than 40% by weight, a cation-dyeable polyester fiber in an amount of more than 30% by weight and less than 40% by weight, a polyacrylic synthetic fiber in an amount of more than 25% by weight and less than 30% by weight, and a polyurethane elastic fiber in an amount of more than 5% by weight and less than 10% by weight, wherein the fabric has a friction-charged electrostatic potential of 1500 V or less and wash-and-wear properties, as determined according to Method 124 in AATCC after being laundered five times in accordance with Method 103 in JIS L0217, of grade 3 or higher.

Claims

exact text as granted — not AI-modified
1 . A fabric, comprising:
 a viscose rayon fiber in an amount of more than 30% by weight and less than 40% by weight;   a cation-dyeable polyester fiber in an amount of more than 30% by weight and less than 40% by weight;   a polyacrylic synthetic fiber in an amount of more than 25% by weight and less than 30% by weight; and   a polyurethane elastic fiber in an amount of more than 5% by weight and less than 10% by weight, wherein the fabric has a friction-charged electrostatic potential of 1500 V or less and wash-and-wear properties, as determined according to Method 124 in AATCC after being laundered five times in accordance with Method 103 in JIS L0217, of grade 3 or higher.   
     
     
         2 . The fabric according to  claim 1 , wherein the fabric has an exothermic property caused by moisture absorption of at least 2.6° C. 
     
     
         3 . The fabric according to  claim 1 , wherein the fabric takes not longer than 40 minutes to decrease its diffusible remaining water content to 30% or lower. 
     
     
         4 . The fabric according to  claim 1 , wherein the fabric has a warmth retention rate of 14% or more. 
     
     
         5 . The fabric according to  claim 1 , wherein the fabric has a pilling grade of 2.5 or higher. 
     
     
         6 . The fabric according to  claim 1 , wherein the cation-dyeable polyester fiber includes a fiber having a modified cross-section. 
     
     
         7 . The fabric according to  claim 1 , wherein the fabric is a knitted fabric of monolayer structure. 
     
     
         8 . A garment manufactured by using the fabric according to  claim 1 . 
     
     
         9 . The fabric according to  claim 2 , wherein the fabric takes not longer than 40 minutes to decrease its diffusible remaining water content to 30% or lower. 
     
     
         10 . The fabric according to  claim 2 , wherein the fabric has a warmth retention rate of 14% or more. 
     
     
         11 . The fabric according to  claim 3 , wherein the fabric has a warmth retention rate of 14% or more. 
     
     
         12 . The fabric according to  claim 2 , wherein the fabric has a pilling grade of 2.5 or higher. 
     
     
         13 . The fabric according to  claim 3 , wherein the fabric has a pilling grade of 2.5 or higher. 
     
     
         14 . The fabric according to  claim 4 , wherein the fabric has a pilling grade of 2.5 or higher. 
     
     
         15 . The fabric according to  claim 2 , wherein the cation-dyeable polyester fiber includes a fiber having a modified cross-section. 
     
     
         16 . The fabric according to  claim 3 , wherein the cation-dyeable polyester fiber includes a fiber having a modified cross-section. 
     
     
         17 . The fabric according to  claim 4 , wherein the cation-dyeable polyester fiber includes a fiber having a modified cross-section. 
     
     
         18 . The fabric according to  claim 5 , wherein the cation-dyeable polyester fiber includes a fiber having a modified cross-section. 
     
     
         19 . The fabric according to  claim 2 , wherein the fabric is a knitted fabric of monolayer structure. 
     
     
         20 . The fabric according to  claim 3 , wherein the fabric is a knitted fabric of monolayer structure.
