HT Fine Textile Chemical Auxiliary Agent

L eveling agent in textile   are essential to enhance the added value of textiles, not only make the textile functional, but also make its high-grade, more with the sense of the times. In order to have these advantages, the premise is the fabric dyeing to be evenly permeable, a very effective method that using leveling agent which features in slow dye or migration to achieve uniform dyeing effect.   In the dyeing process of fiber yarn, line or fabric , in order to promote uniform dyeing without color bars, spots and other added substances, leveling agents are here to use. Most of the leveling agents are water-soluble surfactants, which are divided into two types according to the effect of leveling agent on the diffusion and aggregation of dyes: one is fibrous leveling agent, which has little effect on the concentration of dyes. But the affinity of the fiber is greater than the affinity of the dye to the fiber, so in the process of dyeing, this kind of leveling agent will be co...

  Softening agent   is a kind of chemical material that can change the static and dynamic friction coefficient of fiber. When the static friction coefficient changed, the touch has a smooth feeling and easy to move on the fiber or fabric; when the dynamic friction coefficient changed, the micro structure between the fibers easy to move within each other, that is, the fiber or fabric is easily deformed. The combination of these two feelings is soft   From the ionic classification, textile softeners can be divided into anion type, cationic type and nonionic softening agent. Main component classification, because the basic composition of softener is mainly long-chain fatty acid (saturated or unsaturated) derivative and Silicone II, it can be divided into fatty acid softener, silicone softener, fatty acids and silicone blends. At present, the market for low gear softener is often the fatty acids and silicone mixtures of such products.   Softening finishing is an importan...

  Fixing agent   is one of the important textile auxiliaries in dyeing and printing industry, which can improve the color fastness of dye in fabric. On the fabric, it can form insoluble colored material with dye, thus to improve the color of washing, perspiration fastness, and sometimes can improve its sun fastness.   In recent years, with the development of science and technology, dyeing and finishing technology has also been significantly improved. Due to the expansion of international textile trade and the improvement of people's living standards and environmental awareness, it's more required of textiles comfort, clean and safety. Since the 1970s, Germany first launched the "Blue Angel" plan, the world's developed countries (Japan, the United States, etc.) have passed and implemented the related laws, regulations, and rules for the various indicators of textiles. Green textiles require that in the printing and dyeing process prohibit the use of carcinogenic, t...

This dye-fixing agent will combine some groups in fiber dye molecules and form covalent bond, which is helpful to the fastness. The commonly used reactive dye-fixing agent is as follows: (1)The reactive cationic resin type fixing agent is usually produced by the reaction of diethylenetriamine , dicyandiamide and the epichlorohydrin (the introduction of epoxy group). It can not only improve the color fastness of direct dyes and acid dyes, but also does not change the color. (2)Polyether reactive fixing agent, is a kind of non-ionic polyether fixing agent produced by the reaction of polyether and epichlorrohydrin. This agent has a certain solubility in water. It can be cross-linked into macromolecular network structure in itself. Combining with dye, it will form large mole...

Textile auxiliaries to improve the quality of textile products and added value has an indispensable role, it can not only give the textile a variety of special features and styles, such as soft, wrinkle-free, anti-shrink, waterproof, anti-bacterial, anti-static, Etc., can also improve the dyeing and finishing process, play a role in saving energy and reducing processing costs. Textile auxiliaries to enhance the overall level of the textile industry and the role in the textile industry chain is essential.   Common textile auxiliaries Scouring agent, dyeing agent, leveling agent, softener, hair effect lifting agent, polyester low temperature dyeing carrier, substitute alkali, CT powder, chemical fiber oil, high efficiency retreat powder, hydrogen peroxide stabilizer, in addition to silicon, Pilling agent, fixing agent and so on.   HT is a pr...

  Time: 2017-06-27  Click: 1517 The functional finishing of textiles is to satisfy certain special use requirements of textiles, and special finishing methods are given to the good use, safety and appearance of textile. Multi-functional textile finishing agent is a kind of functional finishing agent which is developed with the development of textile chemicals, biological medicine, polymer composite materials, photo chemical, thermodynamics, electricity, ecology and so on. Because the functional finishing of textile is to be aimed at the specific performance of the textile, strong purpose, excellent effect, and high added value of product.   1. The requirements of functional finishing   Good environmental protection, the production of functional textiles will not have an impact on the ecological environment. Harmful effluent, harmful gas and sewage discharge will directly result in soil and groundwater pollution, resulting in deterioration of natural ecological enviro...
