Study on Dyeing Properties of WP/PP Fiber

In this paper,the dyeing process and property of disperse dyes on WP/PP fiber were studied.The mechanism of normal pressure dyeing on the WP/PP fiber was discussed.The K/S value and the color fastness of fabric were determined.The results showed that the dyeing ability of WP/PP fiber was obviously better and the ratio of dye up-take was one times higher than that of PP fiber.The optimum dyeing conditions for the WP/PP fiber was as the following:the dye temperature was 95 ℃,the dyeing time was 45 min,the concentration of carrier Dilatin POE was 0.8 g/L.The color fastness to laundering,perspiration and crocking were excellent after the WP/PP fiber has been dyed with disperse dyes of Foron.
