METHOD FOR DYEING MIXED FIBERS

摘要

A fiber mixture containing cellulosic and polyester fibers is dyed with a reactive dye at least 60 % of which is fixed to the cellulosic fibers at a pH of 9.0 to 12.0 and a bath temperature of 50 to 85 ~C and an alkali-fast disperse dye at least 90 % of which is fixed to the polyester fibers at a pH of 8.0 to 11.0 and a bath temperature of 120 to 140 ~C.
