Shrinkproof Finish of Viscose Rayon Fabric
초록
100% viscose rayon fabric was treated with 1,2,3,4-butanetetracarboxylic acid (BTCA) by pad-dry-cure process in the presence of various catalysts. The dimensional stability, mechanical properties and hand values of fabric treated with BTCA were investigated. The ester-crosslinking reaction was influenced by the concentration of BTCA and type of catalyst. The fabric treated with BTCA was comparable or superior to that treated with conventional crosslinking agents such as dimethyloldihydroxyethyleneurea and 4,5-dihydroxy-1,3-dimethyl-2-imidazolidinone in respect of wrinkle recovery, shrinkproof property, retention of strength, and hand values. But in yellowing of fabric, the fabric treated with BTCA was inferior to that treated with conventional crosslinking agents. The fabric treated with BTCA/sodium formate was inferior to that treated with BTCA/sodium hypophosphite in respect of WRA, but had better strength retention and whiteness.
