Embodiment 1

[0029] A polyester chiffon printing and dyeing process, including pre-treatment, dyeing treatment and post-treatment, the specific dyeing process is: put the polyester chiffon in a low-concentration dyeing solution at room temperature for 40 minutes, take out the polyester chiffon, and directly put it in the temperature Dip-dye in a high-concentration dye solution at 85°C for 60 minutes. After the high-concentration dye solution cools down naturally, take out the polyester chiffon to complete the dyeing; the mass ratio of the polyester chiffon to the low-concentration dye solution is 1:30; the low-concentration dye solution The pH value of the solution is 6.5; the mass ratio of polyester chiffon and high-concentration dye solution is 1:40; the pH value of high-concentration dye solution is 4.5;

[0030] The post-treatment is as follows: dry the dyed polyester chiffon, add octadecyl dimethyl tertiary amine with a concentration of 3.33g / L, polyether modified silicone oil with a c...

Abstract

The invention discloses a polyester chiffon printing and dyeing process. The polyester chiffon printing and dyeing process comprises pretreatment, dyeing treatment and posttreatment, wherein the dyeing treatment comprises the following steps: putting polyester chiffon into a low-concentration dying solution, performing dip dyeing, taking out the polyester chiffon, directly putting into a high-concentration dying solution, performing dip dyeing, and after naturally cooling the high-concentration dying solution, taking out the polyester chiffon to finish dyeing; the posttreatment comprises the following steps: drying the dyed polyester chiffon, putting into a mixed solution of a softening agent and a color fixing agent, soaking, drying, putting into a soaping box, cleaning, then drying and warehousing; the low-concentration dying solution comprises the following raw materials: dye, a cationic surfactant, a dispersant and cyclohexane; the high-concentration dying solution comprises the following raw materials: dye, a cationic surfactant, a dispersant, a color fixing agent and deionized water. The polyester chiffon printing and dyeing process is simple; by the polyester chiffon printing and dyeing process, the polyester chiffon is dyed under the conditions of room pressure and low temperature, is high in dyeing rate, is uniformly dyed, and is high in fastness, good in softness and antistatic.

Description

technical field [0001] The invention relates to the field of general printing and dyeing methods for textiles, in particular to a polyester chiffon printing and dyeing process. Background technique [0002] Chiffon fabrics are light, transparent, soft and elegant, mainly including silk chiffon and polyester chiffon. Among them, silk chiffon is cool and breathable, has strong moisture absorption, and is good for the skin, but there are problems such as easy graying and lightening after washing too much, yellowing after exposure to the sun, need to be washed by hand, easy to stretch yarn, and easy to tear at the seam; polyester chiffon Although there are problems such as poor hygroscopicity, easy to be charged with static electricity, and stained with dust, it is not easy to decolorize, is not afraid of exposure to the sun, can be machine washed, has good firmness, and is cheap, so it has become a commonly used fabric in summer. Polyester chiffon has strong hydrophobicity. Th...
