In Japan, Nippon Kayaku Co., Ltd. developed a series of KAYALON Polyester LW (9 items included), dyestuffs specialized for polyester/polyurethane blended stretch fabric and have been available on the market since July 1998. Other dyestuff makers have also reacted to this and are also introducing new dyestuffs to compete. It seems possible that more dyestuffs and auxiliaries for polyester/polyurethane blended stretch fabric will be available soon. Consequently, there is no doubt that Japanese synthetic fiber makers will expand the production of polyester/polyurethane blended fabric.
