WIPO Patent Application WO/2005/093153
Kind Code:
A1
Abstract:
A dyeing method by which sufficient color fastness can be imparted to a polyester/polyurethane composite fiber even when the polyester/polyurethane composite fiber is dyed with a disperse dye, and which can sufficiently reduce the contamination of especially a dry-cleaning fluid. The method of dyeing a polyester/polyurethane composite fiber with a disperse dye comprises: subjecting the composite fiber to pretreatments comprising a first step (1) in which the fiber is treated with a treating liquid containing a polyhydric phenol compound and a second step (2) in which the composite fiber treated in the step (1) is treated with a treating liquid containing a polyamine or a salt thereof; and (3) dyeing the composite fiber which has undergone the pretreatments with a dye liquor containing the disperse dye and a polyhydric phenol compound.
