Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cashmere fiber dyeing, in particular to a cashmere fiber dyeing method convenient to maintain. BACKGROUND

[0002] Compared with wool, cashmere is more sensitive to acid, alkali and heat, and the scales of cashmere are more prone to damage at high temperature, exposing the cortex layer and making the fiber hydrolysis phenomenon more serious. Therefore, in cashmere dyeing, the dyeing temperature needs special attention. In processing, the cashmere is first cleaned, then the cashmere is subjected to cake forming operation, then the cake-formed cashmere is lifted out of the dyeing pot using a crane, and is placed in the dyeing pot for high-temperature immersion dyeing. After the immersion dyeing is completed, the cake is lifted out of the dyeing pot using a crane, and is subjected to centrifugal dewatering. After dewatering, the cake is turned over, broken up and then dried and transported.

[0003] Because the bottom of the traditional fiber cage directly collides with the dyeing pot when the fiber cage is lifted into the dyeing pot, the fiber cage and the dyeing pot are damaged. After cake pressing, the dye easily forms lumps, and the dyeing pot has fixed spray hole positions, so that dyeing can only be carried out by spraying through the spray holes. After cake pressing, the outer layer of the fiber cashmere is more likely to obtain the immersion dye, and the inner layer needs a period of time to enter the dye, resulting in uneven dyeing. After the dyeing is completed, the cashmere is subjected to alkali washing and color fixing treatment to ensure that the unreacted and hydrolyzed dyes are completely removed from the surface of the fiber. Generally, the color fastness of deep or special deep colors can only meet the standard after 2 times of alkali washing and color fixing treatment. After alkali washing, the dye bath residual liquid has a relatively thick color, and deep colors need to be washed with cold and hot water for 8-10 times to completely remove the dyes that are not reacted and hydrolyzed and adsorbed on the surface of the fiber. This repeated heating and cold-hot water washing and changing steps make it difficult for the inner layer of the fiber cage to be washed, and the outer layer of the fiber is damaged due to long-term repeated washing. In addition, the long dyeing post-treatment time leads to high raw material consumption and large wastewater discharge. Therefore, we propose a cashmere fiber dyeing method convenient to maintain.
