摘要： To provide elastic fabric that has comfortable wear and fit even in thin and light fabric by using a high-powered polyurethane elastic fiber that has at least 1.5 times the active force and recovery per unit fineness at the time of 100 to 200% elongation compared to conventional polyurethane elastic fiber. Resolution means an elastic fabric comprising a polyurethane elastic fiber made of a polyol, with a molecular weight between 450 and 1600 with a ratio of weight average molecular weight to number average molecular weight of at least 1.8, an organic diisocyanate compound, and a diamine compound.
