Silicone is mainly used as lubricant, fabric finishing agent, defoaming agent and anti-sticking agent for yarn and textile machinery in textile industry, which plays an important role in improving textile quality and technology.
1, silicone fabric finishing agent
Although synthetic fiber has many excellent advantages, but the feel is relatively rough and hard, affecting the visual effect, tactile effect and use performance of the fabric, so it is necessary to finish the fiber and textile. Silicone fabric finishing agent has good comprehensive properties, not only can meet the wear resistance, tear resistance, wrinkle resistance, crisp, ironing, and feel soft, elastic and super smooth, so it is widely used.
(1) pure silk fabric and silk knitwear anti-wrinkle, avoid ironing finishing after finishing of silk fabric has soft, thick, smooth, high elasticity, wrinkle resistance, applications include shrinkage of pure silk crease resistant finishing, pressing silkworm silk soft finishing, triacetate/nylon imitation silk fabric softening, silk knitwear from iron, etc.
(2)The outstanding advantage of silicone wool finishing agent is that the wool does not degrade chemically in the process of finishing, at the same time, it reduces pilling and is resistant to dry cleaning. Moreover, the finished clothes still retain the original softenness of the wool, which achieves the effect of super washable or "emboss". It is applied to the shrunk-proof finishing of woolen sweaters and the finishing of thin woolen blended fabrics
(3) fabric water-repellent finishing Various fabrics treated with silicone water-repellent agent can get the following effects: waterproof, bulky, soft, breathable, elastic, washable, wrinkle-resistant, but also increase the wear resistance, tear strength and smooth hand feel of the fabric, improve its sewing performance. It can be used for water repellent finishing of vinylon tarpaulin, polyester/cotton fabric, nylon silk, etc.
(4) Used as the soft finishing of polyester chemical fiber fabric, it can make the fabric feel soft, smooth, crisp, elastic and have a certain fullness, and can improve the crease resistance, tear strength and air permeability to a large extent. It can be used for soft finishing of pure polyester knitwear, yarn-dyed polyester/viscose medium length fabrics, etc.
2, non-woven fabric and fabric silicone coating
Silicone as a non-woven fabric softener, both strong and soft, cutting and sewing is easier, but also can reduce the surface tension of the resin binder, so that the resin evenly spread on the surface of the fiber, improve the utilization rate of binder. Silicone fabric coating can improve the elongation and elongation recovery of knitwear, improve the wear resistance, shrinkage resistance, pressure track resistance, and can produce a kind of elastic hand memory, promote the fabric in the process of wearing and after washing to restore to a certain balance position.
3. Sanitary finishing of textiles
Sanitary finishing is also called anti-bacteria, anti-odor, anti-corrosion, anti-mildew finishing. Organosilicon quaternary ammonium salt has bacteriostatic effect lasting, safe and reliable, and the advantages of wide antibacterial, health finishing can achieve the best antibacterial mouldproof, and has an excellent deodorization performance, the socks, sweaters, underwear, sportswear, carpet, household products, mouldproof, deodorization finishing as well as the ancient cultural relics protection and adornment, Medical surgery knife disinfection and so on have excellent effect.
4, printing and dyeing process defoaming
Silicone defoaming agent has the characteristics of small dosage, good effect, harmless to biology, can reduce pollution, no effect on other additives in the dye bath, does not affect the color fastness, so more and more attention. Silicone defoaming agent can be used silicone oil, silicone oil mixture, silicone oil solution and emulsified silicone oil four forms, in application is divided into non-aqueous defoaming and water defoaming. It can be used in silk industry, bleaching industry, knitting industry and other dyeing, washing, bleaching, surface treatment, pulp removal, resin finishing, printing and dyeing, printing and dyeing solvent recovery, dry cleaning, jet dyeing, mercerization, non-woven fabric and carpet production process of defoaming.
5. Silicone lubricant and anti-sticking agent
Silicone compounds have very low surface tension, can uniformly wet the surface of synthetic fiber, or form a film on the surface of its lubrication, and good thermal stability, less weight loss, can reduce the generation of carbon powder and waste oxygen, thereby reducing air pollution. In addition, silicone can still maintain its lubricity when heated, can reduce the stop time, so silicone as yarn surface and printing and dyeing machinery lubricant anti-adhesion agent, has been widely used in the textile industry.
(1) As the lubricant of high-speed polyester sewing thread, the polyester cored thread finished with silicone oil emulsion greatly improves its heat resistance and wettability. Dacron sewing thread can be oiled either by impregnation or by contact or by a combination of impregnation and contact.
(2) to reduce the yarn pulp, woven yarn breaking rate of protection finishing
(3) Anti-stick finishing of polyester fiber rewashing
(4) Application of silicone oil lubricant additive on loom
(5) silicone oil as a lubricant for spinning pipes, etc
(6) ethyl silicone oil as lubricant additive for cloth machine
(7) silicone grease, silicone oil as printing and dyeing machinery high temperature resistant lubricant
(8) anti-contamination finishing of chemical fiber spinnerets and printing and dyeing VAT
