Embodiment 1

[0032] Step 1. First add lye to the dyeing vat, then place the chemical fiber textile to be dyed in the dyeing vat for padding lye treatment;

[0033] The lye is a mixture of sodium hydroxide 6g / L, polyoxyethylene fatty alcohol ether 1g / L, alcohol organic solvent and water, wherein the volume ratio of alcohol organic solvent and water in the lye is 1:2.

[0034] Step 2. Add dye and water into the dyeing vat, soak the chemical fiber textile cloth in the dyeing vat for 1 hour, first raise the temperature to 80°C at a speed of 5°C / min and keep it warm for 2 hours, then raise the temperature at a speed of 2°C / min to 85°C; the bath ratio of chemical fiber woven fabrics is 1:20;

[0035] The composition of the dyeing agent is: diphenyl ether tetra-acid dianhydride 9g / L, polypropylene glycol 3g / L, mica powder 18g / L, zinc stearate 2g / L, propyl acetate 5g / L, iron oxide red 10g / L, Ethyltriethoxysilane 7g / L, sodium hydroxide 6g / L, sodium carbonate 4g / L, ethanol 4g / L, water 41g / L, polyvi...

Embodiment 2

[0041] Step 1. First add lye to the dyeing vat, then place the chemical fiber textile to be dyed in the dyeing vat for padding lye treatment;

[0042] The lye is a mixture of sodium hydroxide 15g / L, polyoxyethylene fatty alcohol ether 4g / L, alcohol organic solvent and water, wherein the volume ratio of alcohol organic solvent and water in the lye is 1:3.

[0043] Step 2. Add dye and water to the dyeing vat, soak the chemical fiber textile cloth in the dyeing vat for 1.5 hours, first raise the temperature to 70°C at a speed of 4°C / min and keep it warm for 2 hours, then raise the temperature at a speed of 1.5°C / min to 88°C; the bath ratio of chemical fiber woven fabrics is 1:20;

[0044] The composition of the dyeing agent is: diphenyl ether tetra-acid dianhydride 9g / L, polypropylene glycol 4g / L, mica powder 19g / L, zinc stearate 3g / L, propyl acetate 5g / L, iron oxide red 10g / L, Ethyltriethoxysilane 8g / L, sodium hydroxide 7g / L, sodium carbonate 5.5g / L, ethanol 4.5g / L, water 40g / L...

Embodiment 3

[0050] Step 1. First add lye to the dyeing vat, then place the chemical fiber textile to be dyed in the dyeing vat for padding lye treatment;

[0051] The lye is a mixture of sodium hydroxide 10g / L, polyoxyethylene fatty alcohol ether 4g / L, alcohol organic solvent and water, wherein the volume ratio of alcohol organic solvent and water in the lye is 1:5.

[0052] Step 2. Add dye and water to the dyeing vat, soak the chemical fiber textile cloth in the dyeing vat for 2 hours, first raise the temperature to 80°C at a speed of 5°C / min and keep it warm for 2 hours, then raise the temperature at a speed of 2°C / min to 89°C; the bath ratio of chemical fiber woven fabrics is 1:20;

[0053]The composition of the dyeing agent is: diphenyl ether tetra-acid dianhydride 9.5g / L, polypropylene glycol 3g / L, mica powder 20g / L, zinc stearate 3g / L, propyl acetate 5g / L, iron oxide red 11g / L , ethyltriethoxysilane 8.5g / L, sodium hydroxide 7.8g / L, sodium carbonate 6.2g / L, ethanol 4g / L, water 43g / L...

Abstract

The invention discloses a method for dyeing textile cloth. The method includes putting to-be-dyed chemical fiber textile cloth in a dyeing vat to perform pre-dyeing treatment; adding dyeing agents andwater into the dyeing vat, soaking the chemical fiber textile cloth in the dyeing vat for 1-2 hours, and increasing the temperature; drying the soaked chemical fiber textile cloth in an environment with the temperature of 85-95 DEG C; subjecting the treated chemical fiber textile cloth to fixation treatment; washing the treated chemical fiber textile cloth to remove surface dye, and drying the cloth at 70-80 DEG C. In a pad dyeing process of a textile product, the hydrolysis rate of dyestuff in dye liquor can be reduced, the utilization rate, dye-uptake rate and level dyeing rate of the dyestuff can be increased, and the fixation rate of the dyestuff to the textile product can be also increased.

Description

technical field [0001] The invention belongs to the technical field of dyeing technology, and relates to a method for dyeing textile fabrics. Background technique [0002] The traditional dyeing method of carrier and high temperature will seriously damage the fiber strength of chemical fiber textile fabrics, and it is difficult to dye deep, thick and bright colors, and it is easy to fade in the daily cleaning process. Contents of the invention [0003] The purpose of the present invention is to provide a method for dyeing textile fabrics, which solves the problem that the existing dyeing process is easy to fade in the daily cleaning process after dyeing. [0004] The technical scheme adopted in the present invention is a method for dyeing textile fabrics, comprising the following steps: [0005] Step 1. First arrange the chemical fiber textiles to be dyed in the dyeing vat, and perform pre-dyeing treatment; [0006] Step 2. Add dyeing agent and water to the dyeing vat, s...
