Investigation on bleaching of fox cashmere.

Due to the thermal treatment and the role of various chemical reagents in the bleaching process, the cashmere fiber's strength is decreased, the spinning property and rate of successful waving is weakened and the good quality characteristics, such as good elasticity, smooth waxy feel, warmth, can not be maintained. The detergent treatment process and conventional bleaching process are separately used to deal with the cashmere fibers, the whiteness and strength of the treated fibers are compared and then the optimal process conditions of each process are determined. The results show that under the premise of treated fiber' s whiteness and strength, the detergent treatment process is simple, the processing time is short and the type and usage of additives is fewer than conventional bleaching process, thereby reducing the damage of fiber, ensuring the treated fiber's good quality, which is good for the follow - up processing of cashmere products and can also saving energy and reducing costs.
