Embodiment 1

[0008] A water-saving dyeing method for yarn described in this example, put the yarn in a container, add water 10 times the quality of the yarn, and then put in hydrogen peroxide and sodium hydroxide, the amount of hydrogen peroxide is 3% of the yarn quality , the amount of sodium hydroxide is 2% of the yarn mass, and it is kept at 80°C for 30 minutes; then add hydrogen peroxide remover, the amount of hydrogen peroxide remover is suitable for removing hydrogen peroxide; then drain, add clear water, and add to glacial acetic acid And until the pH value is between 7-7.5; then dyeing, post-treatment after dyeing, first put the dyed yarn in the container, add clear water, the amount of clear water is 10 times the quality of the yarn, add glacial acetic acid to When the pH value is between 4-4.5, heat to 40°C, keep warm for 10 minutes, remove the water, add water again, the amount of water is 10 times the mass of the yarn, add soaping agent, the amount of soaping agent is 1% of the ...

Embodiment 2

[0010] A water-saving dyeing method for yarn described in this example, put the yarn into a container, add clear water 20 times the quality of the yarn, and then put in hydrogen peroxide and sodium hydroxide, the amount of hydrogen peroxide is 6% of the yarn quality , the amount of sodium hydroxide is 3% of the yarn mass, and it is kept at 90°C for 40 minutes; then add hydrogen peroxide remover, the amount of hydrogen peroxide remover is suitable for removing hydrogen peroxide; then drain, add water, and add to glacial acetic acid and until the pH value is between 7-7.5; then dyeing, post-treatment after dyeing, first put the dyed yarn in the container, add clear water, the amount of clear water is 20 times the quality of the yarn, add glacial acetic acid to When the PH value is between 4-4.5, heat to 50°C, keep warm for 20 minutes, remove the water, add water again, the amount of water is 20 times the mass of the yarn, add soaping agent, the amount of soaping agent is 3% of th...

Embodiment 3

[0012] A water-saving dyeing method for yarn described in this example, put the yarn into a container, add clear water 15 times the quality of the yarn, and then put in hydrogen peroxide and sodium hydroxide, the amount of hydrogen peroxide is 5% of the yarn quality , the amount of sodium hydroxide is 3% of the yarn mass, and it is kept at 85°C for 35 minutes; then add hydrogen peroxide remover, the amount of hydrogen peroxide remover is suitable for removing hydrogen peroxide; then drain, then add clear water, and add to glacial acetic acid And until the pH value is between 7-7.5; then dyeing, post-treatment after dyeing, first put the dyed yarn in the container, add clear water, the amount of clear water is 15 times the quality of the yarn, add glacial acetic acid to When the pH value is between 4-4.5, heat to 45°C, keep warm for 15 minutes, remove the water, add water again, the amount of water is 15 times the quality of the yarn, add soaping agent, the amount of soaping age...

Abstract

The invention relates to the technical field of yarn dyeing, in particular to a water-saving yarn dyeing method. The method includes: adding yarns into a container, adding clear water being 10-20 times of mass of the yarns, then adding hydrogen peroxide and sodium hydroxide, and keeping the temperature at 80-90 DEG C for 30-40min; adding a hydrogen peroxide removing agent, draining, adding clear water, and adding glacial acetic acid to neutralize until a PH value is in a range of 7-7.5; dyeing, performing aftertreatment, putting the dyed yarns in the container, adding clear water, adding glacial acetic acid until the PH value is in a range of 4-4.5, heating to 40-50 DEG C, keeping the temperature for 10-20min, removing water, adding clear water again, adding a soaping agent, keeping the temperature at 60-80 DEG C for 10-20min, adding a softening agent, keeping the temperature for 10-15min, washing cleanly and dewatering. The water-saving yarn dyeing method has advantages that by a reasonable pretreatment and after-treatment process, yarn dyeing performances and coloring efficiency are remarkably improved, water consumption in the pretreatment and after-treatment process can be reduced, and dyeing cost is sharply reduced.

Description

technical field [0001] The invention relates to the technical field of yarn dyeing, in particular to a water-saving dyeing method for yarn. Background technique [0002] In the prior art, the dyeing of yarns requires pretreatment, dyeing, and posttreatment. The one-bath method used in the dyeing process can save water, but a large amount of water is required in the pretreatment and posttreatment processes, resulting in The water consumption is large and the dyeing cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a kind of water-saving dyeing method of the yarn that can save a lot of water in the pre-treatment and post-treatment in order to solve the deficiency of above-mentioned technology. [0004] In order to achieve the above-mentioned purpose, a kind of water-saving dyeing method of yarn designed by the present invention, yarn is put into container, add the clear water of 10-20 times of yarn quality, then put into hyd...
