Abstract

The invention discloses a no-wash dyeing process of skein. The no-wash dyeing process comprises the following steps: S1, soaking the skein into water at room temperature; S2, adding a no-wash agent into the water after 10 to 20 minutes, wherein the adding amount of the no-wash agent is 1 to 2 g / L of water; S3, adding organic acid into the water after 5 to 10 minutes, wherein the adding amount of the organic acid is 2 to 4g / L of water; S4, adding a levelling agent into the water after 5 to 10 minutes, wherein the adding amount of the levelling agent is 1 to 2g / L of water; S5, adding dye into the water after 10 to 20 minutes; S6, raising the temperature from the room temperature to 95 to 100 DEG C according to the speed of 1 to 2 DEG C / min and carrying out thermal insulation for 30 to 60 minutes; cooling to room temperature and taking out the skein to obtain the dyed skein. According to the no-wash dyeing process disclosed by the invention, by improving the dyeing process and omitting the pretreatment (washing line) procedure, energies of human power, materials and financial resources, especially water, electricity and gas are saved and a great promoting effect on energy conservationand emission reduction is achieved; the work efficiency is improved and the production cost is reduced due to the reduction of the process flow.

Description

Technical field: [0001] The invention relates to a skein free dyeing process. Background technique: [0002] Since the skein yarn needs to add additives such as oil during the spinning process, and wool or other fibers must contain a certain amount of oil, dust, impurities, etc. before processing. Therefore, the oil and impurities must be washed by equipment such as a thread washing machine, so as to help dye the color well and improve the color fastness. Because of this, the traditional skein dyeing must be pre-treated before the yarn is loaded into the cylinder. In the pre-treatment process, a large amount of water and additives are needed to clean the skein, which wastes a lot of manpower, material resources, and financial resources. The prior art does not have a solution to this. Invention content: [0003] The invention provides a wash-free dyeing process for skeins, which does not need to be cleaned in advance before dyeing the skeins, and solves the problems in t...
