Abstract

The invention relates to the technical field of dyeing, in particular to a purple dyeing method of acrylon, comprising: placing water and acrylon in a dye vat, heating to 70 DEG C, adding an aid, holding the temperature for 10 min, adding a dye, holding the temperature for 10 min, heating to 100 DEG C at a speed of 1 DEG C/min, holding the temperature for 30 min, cleaning, lowering the temperature to 40 DEG C, adding a wool bleaching agent, heating fast to 60 DEG C, holding the temperature for 10 min, cleaning, lowering the temperature for 40 DEG C, adding a soaping agent, heating fast to 90 DEG C, holding the temperature for 20 min, cleaning, lowering the temperature to 40 DEG C, adding a softening agent, holding the temperature for 20 min, and removing from the vat. The purple dyeing method of acrylon according to the invention enables dyed acrylon to reach level 3 of color fastness without producing color defects, the production process is relatively short, and energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a purple dyeing method for acrylic fibers. Background technique [0002] After the existing acrylic fiber is dyed, its color fastness is relatively poor, and the problems of uneven dyeing and color flower 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 purple dyeing method of the acrylic fiber of uniform dyeing. [0004] In order to achieve the above purpose, the purple dyeing method of acrylic fiber designed by the present invention is to put water and acrylic fiber into the dyeing vat, add auxiliary agent after heating up to 70°C, keep warm for 10min, add dye, keep warm for 10min, and use 1°C / min Speed ​​up to 100°C, keep warm for 30 minutes, wash clean, drop the temperature to 40°C, add bleaching agent, quickly heat up to...
