IMPARTMENT OF DYE-PROOF PROPERTY OR MULTICOLOR EFFECT TO NATURAL AND SYNTHETIC POLYAMIDE FIBER MATERIAL

摘要

PROBLEM TO BE SOLVED: To exhibit dye-proof effect and multicolor effect by locally applying a blend containing a specific dye-proofing agent to natural and synthetic polyamide fiber material by wet on wet before or after dyeing or printing the polyamide fiber material with an anion dye and then heat-treating the blend. SOLUTION: A liquid blend containing one or two or more kinds of compounds represented by the formula (R1 is a 10-24C alkyl or alkenyl; R2 and R3 are each a 1-4C alkyl; X is an anion group) is locally applied to a woven fabric comprising a natural polyamide fiber such as wool or a synthetic polyamide fiber such as polyamide 6 or 66 by wet on wet before or after carrying out base dyeing with a dyeing solution containing at least one kind of anion dye having <5 K value or printing by a printing paste and then subjected to steam heat treatment to fix the anion dye to the woven fabric.
