METHOD FOR PRODUCING DYED TEXTILES COMPRISING POLYPROPYLENE FIBRES

摘要

The invention relates to a method for producing dyed textiles comprising polypropylene fibres, according to which polypropylene (A) is first mixed into the melt together with polymers (B) that can be thermoplastically processed and block copolymers (C), the latter having polar and non-polar blocks, and the mixture is then processed to form undyed polypropylene fibres. Said fibres are processed to form textiles and the textiles are then dyed in an aqueous bath or printed. The invention also relates to undyed polypropylene fibres that are particularly suitable for carrying out said method.
