Problems solved by technology

At the same time, a series of studies have also been carried out on the application conditions and effects of various color-fixing agents; among them, cationic surfactant-based color-fixing agents have better color-fixing effects in most cases, but are not resistant to soaping, and It tends to reduce the original light fastness of the dye; the non-surfactant quaternary ammonium salt-type color fixing agent can improve the color fastness, especially the washing fastness, and has little effect on the color and light fastness of the dyed matter. However, it has a certain influence on the strength of the fabric, and does not greatly improve the soaping fastness; the resin-type color fixing agent is a color fixing agent widely used in direct dyes, but there are certain shortcomings, such as color fixing agent Y After use, it will affect the shade of the fabric and contains formaldehyde. When the color fixing agent M is used, copper salt needs to be added to prevent the decline of light fastness, but it has a great impact on the shade of the fabric, especially when encountering iron ions. , there are also some resin-type color-fixing agents that have shortcomings such as poor fastness to hot water; the reactive color-fixing agent is a new type of color-fixing agent developed recently (Wen Level, printing and dyeing auxiliaries, 2000, Vol17, No6, 32-33; Zhu Guohua, Guan Yonghua, Journal of Nantong Institute of Technology, 16(2), 2000, 06, 28-32), has good color fixing effect, and the biggest advantage of this kind of color fixing agent is that it can improve the wet fastness of dyestuffs , and has little effect on color, of course, some color fixing agents have disadvantages, such as color fixing agent NF1, which is easy to cause color change. At present, the development of this color fixing agent is still in further exploration

Embodiment 1

[0033] The synthetic fixing agent structure is:

[0034]

[0035] where R is -CH 2 CH 2 CH 2 Si(OCH 3 ) 3

[0036] 1. Synthesis of chlorinated silicone oil:

[0037] Add 0.10 mol of hydroxysilicone oil (n=4) into the three-necked flask, add 0.20 mol of dimethyldichlorosilane into the dropping funnel, stir at 40°C, and slowly add dimethyldichlorosilane, at this time It can be observed that the liquid in the three-necked bottle will bubble, and a large amount of HCl white gas will be generated during the reaction. After the gas is removed, a colorless or light yellow liquid is obtained.

Abstract

A cationic organic silicon compound of reaction type color-fixing agent, is obtained by: react hydroxy silicone oil, dimethyl dichlorosilicane, amine, siloxane, together with quaternary ammonium agent. The durable color-fixing agent is of environmental protection. It improves color-fixing effect of active dyes in difficulty for color fixing and low fastness for washing. Besides those advantages, it is helpful for softening and has bactericidal effect. It can be used in direct dye and acidic dye to increase the wet fastness in fabrics, improve wear and sunshine tolerance, less influence in colors and tones of fabrics and have brighten and strengthen fuscous.

Description

technical field [0001] The invention relates to a color fixing agent and a preparation method thereof, in particular to a cationic and reactive color fixing agent and a preparation method thereof. Background technique [0002] With the development of the economy, people's needs for basic necessities of life are changing rapidly. At present, people's pursuit of clothing materials is not only beautiful, but also pays more attention to comfort. Cotton fiber has gradually become the main material of people's clothing due to its comfortable and beautiful characteristics. Therefore, high-quality printed and dyed cotton fiber materials are increasingly favored by people. [0003] Anionic water-soluble dyes such as direct dyes and acid dyes have complete chromatograms and brighter shades, but due to the combination of van der Waals force and hydrogen bonds with fibers, and most of the dyes have soluble groups, the wet rubbing fastness is not good. That is, fading and staining are ...
