Abstract

The invention relates to the field of yarn dyeing methods, in particular to an apricot dyeing method for carded slivers. The method includes the steps that the carded slivers are put into a dye vat, water is added and heated to 30 DEG C, auxiliaries are added, and the temperature is kept for 10 min; dyestuff is added, and the temperature is kept for 20 min; the temperature is raised to 70 DEG C at the speed of 1 DEG C / min and kept for 20 min; the carded slivers are cleaned up, and the temperature is cooled to 30 DEG C; a soaping agent is added, the temperature is fast raised to 90 DEG C and kept for 20 min, then the carded slivers are cleaned up and cooled to 30 DEG C; after a softening agent is added, the temperature is raised to 40 DEG C and kept for 20 min, the carded slivers are cleaned up, cooled to 30 DEG C and taken out of the vat. By means of the apricot dyeing method for the carded slivers, the color fastness of the carded slivers can reach the third level after the carded slivers are dyed without a dyeing defect, the production and processing process is short, and energy consumption can be reduced.

Description

technical field [0001] The invention relates to the field of yarn dyeing methods, in particular to an apricot dyeing method for ordinary cotton slivers. Background technique [0002] After the existing common cotton sliver is dyed, its color fastness is relatively poor, and the problems of uneven dyeing and colored flowers are prone to occur. Contents of the invention [0003] The purpose of the present invention is to provide a kind of good color fastness in order to solve the deficiency of above-mentioned technology, the apricot color dyeing method of the common sliver of dyeing evenly. [0004] In order to achieve the above purpose, a kind of apricot dyeing method of ordinary cotton slivers designed by the present invention, put ordinary cotton slivers into the dyeing vat, add water and heat up to 30 ° C, then add auxiliary agents, keep warm for 10 minutes; add dye, keep warm for 20 minutes ; Then raise the temperature to 70°C at a rate of 1°C / min, and keep it warm for...
