  Definition of hydrophilic silicone oil Hydrophilic silicone oil is generally introduced into the polysiloxane side chain, which can improve the hydrophilicity and antistatic properties of silicone oil. The modification of polyether , modified branching chain and the modification of the end base chain and the combination of the both.   Controlling the proportion and position of polyoxyethylene and polyoxypropylene in the polyether macromolecular chains can reach the hydrophilic-lipophilic balance. The integrity of the molecular chain has been destructed by the hydrophilic polysiloxane, which was modified by branched chain, with the result that the soft effect has been decreased. Using the method of end - based modification or block modification can obtain the products with good hydrophilicity and softness.   Features of hydrophilic silicone oil Hydrophilic silicon oil is a kind of micro-size particles and none/ weak cationic amino silicon softener. It has good hydrophili...

  Definition of desizing enzyme Desizing enzymes, is a compound using of microbial fermentation of starch enzymes and other effective substances. Applied in the textile industry, it helps to decompose the starch in the fabric size into short chain dextrin and oligosaccharide, and make it extremely easy to remove in the latter treatment process. Desizing enzymes can be used in cotton, silk, Vinylon, viscose fiber, blended fabric, yarn-dyed poplin and chemical fiber blended fabric.   Desizing process in textile In the weaving process, the fibers need sizing to increase fastness. In the fabric dyeing, bleaching and printing processes, it’s required to remove the size. Desizing is good or bad, directly affect the quality of finished products, such as hand feeling, whiteness, smoothness, color content and strength. Now mostly using starch paste for sizing, and a lot of methods for desizing, such as caustic soda, sulfuric acid, hydrogen peroxide, etc., but these chemical products no...

  Definition of Biopolishing Enzymes With the increasing improvement of the quality and environmental requirements of textile products in modern society, the application of biopolishing enzymes as a natural protein product in textile dyeing and finishing has already been applied. Because the enzyme itself has the characteristics of "easy to complete biodegradation", it is environmentally friendly and does not pollute textiles, thus satisfying the "clean and harmless chemical method" for dyeing and finishing; at the same time, the enzyme-treated textiles can produce many special functions, which greatly improve the wearability and added value of textiles, and can meet the needs of different consumer groups in the market, which have a good prospect for development.   The effect of enzymes on fiber has high specificity and high catalytic efficiency, and when cellulase reacts with cellulose fibers, the enzyme molecule is adsorbed on some parts of cellulose fibers (first...

  Anti Yellowing Agent  Usage In the process of storage and transportation of nylon light fabric, local slight yellowing often occurs, which affects the appearance and quality of fabric. And in this situation, anti yellowing agent is required in the textile processing.   Cause Analysis 1. The plastic packaging bag contains contaminants and BHT (butyl hydroxy phenyl ether), which make chemical reactions with chinlon, resulting in color variation and yellowing. 2. Select yellowing resistant agent to dip or pad. Anti yellowing agent used in Nylon fabric processing Nylon is a preferred fabric for high-grade swimwear, sportswear, casual wear and underwear. White or light-colored fabrics are very easy to produce yellow in high-temperature treatment (such as hot stereotypes, high-temperature die, etc.) or in the transport, storage process, so the nylon fabric must be yellowing-resistant finishing.   The PH value of additive solution has a great effect on the effect of yello...

  Antistatic Agent for Polyester The Problems Of Hydrophobic Synthetic Fiber Fabrics Such As Polyester 1. The wearing comfort of the fabric is bad, and the feeling on wearing process will be stuffy and uncomfortable. 2. The hydrophobicity of the fabric determines that its conductivity is poor and the surface of the fabric is easy to produce static electricity. 3. Electrostatic production also makes fabric easy to adsorb dirt in the process of using, and in the washing process, due to hydrophobic fiber on the affinity of oil, dirt is not easy to remove, and there is a twice stain phenomenon.   Antistatic Agent Finishing Mechanism 1. Hydrophilic finishing is to change the properties of the fiber surface layer so that it is easy to absorb moisture and improve the wear comfort of the fabric. 2. Antistatic finishing is through the formation of fibers containing ionic and/or hygroscopic groups of polymer, improving the conductivity of fiber, to eliminate or prevent electrostatic pro...

  Definition of anti-staining agent    Anti staining agent  is a substance that can prevent dyes from coloring in fabrics or in the dyeing and printing process.   Classification of anti staining agent Anti staining agents can be divided into two categories according to their mechanical and chemical properties. The former has the wax, oil and some inorganic compounds, the latter including acids, bases, salts, oxidants, reductants, etc. There is one special anti staining agent, such as phenylhydrazine sulfonic acid. Some of them are coated on fabrics to prevent contacting with fiber, such as paraffin, turpentine, starch, clay, and barium sulfate. Some anti staining agents take functions by working with the dyes, to invalidate the dyes or to produce precipitates, such as lime, lead sulfate, aluminum sulfate, calcium phosphate, etc. There are also anti stain salts. Advantages of anti staining agent 1. Good anti staining effect, and give the original white cotton fib...

  What is wetting agents in textile processing Substances that make solid materials more susceptible to water immersion. By reducing its surface tension or interfacial tension, so that the water can be expanded on the surface of solid materials, or penetrate the surface, and the solid material wetting. Usually some surfactants, such as sulfonated oil, soap, open powder BX and so on. Also can be soy lecithin, mercaptan, acyl hydrazine and mercaptan acetal, etc.   what is textile sizing chemicals Definition of textile sizing chemicals Different types of water soluble polymers called textile sizing agents/chemicals such as modified starch, polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC), acrylates are used to protect the yarn.   Textile Chemicals List : Wax removing Agent Definition of wax removing agentWax removing agent, also know as wax cleaning agent, is one kind of colorless nonionic liquid, especially used in the pretreatment of textile processing.   Textil...
