Problems solved by technology

Although most reactive dyes have good washing fastness, when dyeing super-dark colors with an amount of more than 5%, for the color matching colors such as reactive brilliant blue, reactive emerald blue, reactive red and black with relatively high blackness, the drying , Wet fastness and washing fastness are relatively low, and some can only reach about 2 grades, which cannot meet the requirements of customers. This problem has not been well resolved so far. question

Embodiment 1

[0010] Example 1: 32s 2*2 cotton spandex lake blue rib fabric

[0011] The dosage of reactive turquoise blue G-X is 4%, the dosage of bright yellow HF-4GL is 0.126%, the dosage of Jingren blue K-HL is 0.053%, Yuanming powder 60g / L, accelerator 2.5g / L after dyeing at 60℃ for 50min , drain off the dye liquor, wash 2 times with cold water, neutralize 1 time with 1% glacial acetic acid at 60°C, wash 2 times with cold water, soap with 1% soaping agent CSP at 80°C for 20min, heat at 98°C Wash 1 time with water, rinse with cold water, and then use 4% leveling agent 1227 to fix the color at 45°C for 20min.

Embodiment 2

[0012] Example 2: 40s pure cotton navy blue mesh cloth

[0013] The dosage of reactive turquoise blue G-X is 1.54%, the dosage of brilliant blue KN-R is 2.05%, the dosage of Wonder dark blue B-2GL is 0.02%, Yuanming powder 60g / L, sodium carbonate 20g / L after dyeing at 60℃ for 50min , drain off the dye liquor, wash 2 times with cold water, neutralize 1 time with 1% glacial acetic acid at 60°C, wash 2 times with cold water, soap with 1% soaping agent CSP at 80°C for 20min, heat at 98°C Wash with water for 1 time, rinse with cold water, and then use 2% leveling agent 1227 and 2% color fixing agent SF to fix the color at 45°C for 20min.

Embodiment 3

[0014] Example 3: 32S C60 / T40*21S C60 / T40 polyester cotton non-brushed cloth (red)

[0015] BH Red 2.5%, BH Yellow 0.68%, Jingren Blue K-HL 0.023%, Yuanming Powder 60g / L, Sodium Carbonate 20g / L, after dyeing at 60℃ for 50min, drain the dye solution, wash in cold water for 2 1% glacial acetic acid was neutralized at 60°C for 1 session, washed with cold water for 2 sessions, 1% soaping agent CSP was soaped at 80°C for 20 minutes, washed with 98°C hot water for 1 session, washed with cold water, and then Use 2% leveling agent 1227 and fix the color for 20min at 80℃.

Abstract

The invention provides a post-treatment fixation process for fabric dyeing. The process comprises the following sequential steps of: after fabric is dyed by a reactive dye, washing with cold water twice, neutralizing once with 1% of glacial acetic acid at 60 DEG C, washing with cold water twice, soaping with 1% of soaping agent CSP at 80 DEG C for 20 minutes, washing with hot water of 98 DEG C twice, cleaning with cold water, carrying out fixation with 2-4% of acrylon leveling agent 1227 at 45 DEG C for 20 minutes or at 80 DEG C for 20 minutes, then washing with water and discharging the cloth. By adopting the process, the rubbing fastness and water washing fastness indexes of the reactive dye can be effectively improved, and the friction fastness and water washing fastness of the dyed fabric can be further effectively improved.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing, in particular to a post-treatment color-fixing process for fabric dyeing. Background technique [0002] Reactive dyes are widely used for dyeing cellulose fibers due to their advantages of complete chromatogram, bright color and easy dyeing. Although most reactive dyes have good washing fastness, when dyeing extra-dark colors with a dosage of more than 5%, for color-matching colors such as reactive brilliant blue, reactive turquoise blue, reactive red, and black with relatively high jet blackness, its dryness is high. , Wet fastness and washing fastness are relatively low, and some can only reach about 2 grades, which cannot meet the requirements of customers. question. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a post-treatment fixing process for dyeing fabrics, which can effectively improve the rubbing fastness and washi...
