PURPOSE: A method for manufacturing polyurethane urea elastic fiber is provided to improve dyeing property of the elastic fiber. CONSTITUTION: A polyurethane urea elastic fiber with improved dyeing property is fabricated using dyeing deposition agent by mixing 0.3-1.0 weight% of acrylic dyeing deposition agent and 0.5-2.0 weight% of urethane dyeing deposition agent. The elastic fiber is prepared by dissolving a solid powder in dimethyl acetamide. The solid power is selected from the group consisting of poly(acrylamide), poly(2-diethylamino)ethylmethacrylate, poly(N,N-diethylacrylamide), poly(N,N-dimethylacrylamide), and poly(N-vinylacetamide). |
