Problems solved by technology

[0002] As the textile industry enters the 21st century, people pay more attention to ecological and environmental issues, and put forward higher requirements for the color fastness of dyed and printed fabrics, especially the color fastness of export products. At present, most color fixing agents contain formaldehyde. However, 70-80% of formaldehyde-free color-fixing agents are resin-based. This type of color-fixing agent improves the color fastness by combining with anionic dyes to form a salt or forming a cationic resin on the surface of the dye, and its color-fixing ability is poor.
For example, the formaldehyde-free color fixing agent DUR of Shanghai Auxiliary Factory and the nofix Exo of Swiss Ciba Company cannot achieve the ideal color fixing effect due to their poor reaction ability or less reactive groups in the molecule.

Embodiment 1

[0026] (1) Neutralization reaction: add trimethylamine 125KG in the stainless steel kettle, neutralize with hydrochloric acid (37%) 28-30KG, keep the temperature at 20-40°C, and adjust the pH value of the product until 5.

[0027] (2) Quaternization reaction: raise the temperature of the reaction kettle to 45-50°C, slowly add 76KG of epichlorohydrin dropwise, complete the dropwise addition within 1.5 hours, and keep the reaction for 4-4.5 hours.

[0028] (3) Polymerization reaction: under the condition of stirring at 20-40°C, slowly drop the mixture of cyanuric chloride 30KG and acetone 24KG into the reaction kettle, and adjust the pH with sodium carbonate (30%) 8-12KG at any time The value is 6.5 until it remains the same after 20 minutes. Raise the temperature to 65-70°C, gradually add a solution of 36KG of hexamethylenediamine and 300KG of water under stirring, and keep the reaction temperature at 65-70°C. After the dropwise addition, keep the temperature for 2.5 hours, an...

Embodiment 2

[0030] Raw material ratio: trimethylamine 140KG, hydrochloric acid (37%) 43KG, epichlorohydrin 80KG, sodium carbonate (30%) 12KG, acetone 28KG, cyanuric chloride 40KG, hexamethylenediamine 45KG, water 400KG, the production process is the same Example 1.

[0031] The using method of color-fixing cross-linking agent of the present invention

[0032] 1. After dyeing, fix the color and use:

[0033] Mix this product with water 10g / l, dip twice, roll twice, and dry.

[0034] 2. Application as a cross-linking agent for pigment printing: add 0.5-0.8% of this product to the pigment printing paste, and then bake after printing. It can significantly improve the rubbing fastness, especially the wet rubbing fastness above half grade. Similarly, the application of DUR and TinofixExo as crosslinking agent for pigment printing has no obvious effect.

[0035] This product (code-named FSE) is compared with the formaldehyde-free color-fixing agent DUR of Shanghai Auxiliary Factory and the n...

Abstract

The present invention relates to a fixation coupling agent. It is made up by using trimethylamine, hydrochloric acid, epichlorohydrin, and cyanuric chloride and hexamethylene diamine through the processes of neutralization, quaternization and polymerization.

Description

Technical field: [0001] The invention relates to a color-fixing cross-linking agent for textile printing and dyeing, which is a color-fixing agent used for textile dyeing, and can be used as a modifier for paint dyeing and a cross-linking agent for paint printing. Background technique [0002] As the textile industry enters the 21st century, people pay more attention to ecological and environmental issues, and put forward higher requirements for the color fastness of dyed and printed fabrics, especially the color fastness of export products. At present, most color fixing agents contain formaldehyde. And 70-80% of formaldehyde-free color-fixing agent belongs to resin type. This kind of color-fixing agent improves the color fastness by combining with anionic dyes to form a salt or forming a cationic resin on the surface of the dyed matter, and its color-fixing ability is poor. For example, the formaldehyde-free color-fixing agent DUR of Shanghai Auxiliary Factory and nofix Exo...
