Embodiment 1

[0031] Embodiment 1: short-process dyeing and finishing process of polyester viscose fabrics, the process is: one-bath method of retreating, boiling, bleaching→presetting→dyeing→setting and finishing;

[0032] Among them, the one-bath method of unwinding, boiling, and bleaching process is that the polyester-viscose fabric is dipped with the pre-treatment solution, steamed at 100°C for 60 minutes, and then washed in six compartments, and the washing temperatures are 90°C, 90°C, 85°C, and 75°C. , 50°C, 50°C washing, tumble drying;

[0033] The composition of described treatment liquid is

[0034] Scouring agent CSP-T07 4g / L

[0035] Chelating agent 3g / L

[0036] Hydrogen peroxide 5g / L

[0037] Hydrogen peroxide stabilizer Goon2011 2g / L

[0038] Sodium hydroxide to adjust pH 10.5-11

[0039] water balance

[0040] The preparation method of described chelating dispersant is as follows (each raw material is in mass parts):

[0041] a. Put 15 parts of ethylenediamine diacetic...

Abstract

The invention relates to a polyester-viscose fabric short-process dyeing and finishing technology. The technology comprises the process: one-bath method desizing, boiling and bleaching, presetting, dyeing, and setting and finishing; the one-bath method desizing, boiling and bleaching process comprises the steps of pad-rolling a polyester-viscose fabric in a pretreatment liquid, steaming for 60 minat the temperature of 100 DEG C, then washing with water and drying; the treatment liquid comprises 4 g / L of a scouring agent, 3 g / L of a chelating agent, 5 g / L of hydrogen peroxide and 2 g / L of a hydrogen peroxide stabilizer, and the pH is regulated to 10.5-11 with sodium hydroxide. A preparation method of a chelating dispersant comprises the steps: a, putting 15 parts of disodium ethylenediamine diacetate and 140 parts of deionized water into a reactor, stirring, and dissolving; and b, firstly adding 8 parts of sodium hydroxide, after dissolving, adding 7 parts of carbon disulfide, and carrying out a reaction for 3 h, to obtain the chelating dispersant. The one-bath method integrates desizing, scouring and bleaching into one, the active and dispersed one-bath method dyeing technology isused, the technological process is shortened, the technological equipment is simplified and energy consumption is reduced.

Description

technical field [0001] The invention relates to a short-process dyeing and finishing process for polyester viscose fabrics, belonging to the field of printing and dyeing processing technology. Background technique [0002] For a long time, most polyester-viscose fabrics are dyed by bleaching, boiling, pre-bleaching and two-bath method. The process time is as long as 10 hours, the production efficiency is low, and a lot of water, electricity, and steam are wasted, and the amount of sewage is large. Through the reduction of the pre-treatment process and one-bath dyeing, the process flow can be shortened, the process equipment can be simplified, and the energy consumption can be reduced. Contents of the invention [0003] The purpose of the present invention is to provide a short-process dyeing and finishing process for polyester viscose fabrics, which simplifies process equipment, reduces energy consumption, and overcomes the shortcomings of existing pretreatment processes. ...
