HYGROSCOPIC AND EXOTHERMIC FIBER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a hygroscopic and exothermic fiber having sufficient durability and exhibiting sufficient fastness to light even in the case of being dyed.;SOLUTION: The hygroscopic and exothermic fiber is subjected to graft polymerization with a hydrophilic vinyl monomer in 5-10% graft polymerization ratio and has its surface coated with a diglycidyl ethylene glycol represented by general formula [1] (n is an integer of 1-3).;COPYRIGHT: (C)2004,JPO
