HT Fine Textile Chemical Auxiliary Agent

The chelating agent, also known as the complexing agent, metal ions locking agent,  water softener . In dyeing factory, it can be used in desizing, refining, bleaching, alkali-decrement, dyeing, soaping, stripping, silk refining, down cleaning, equipment cleaning, water treatment, and other processes. The fouling in the dyeing factory is mainly the mixture of incrustation, silicon scale, fouling, some fouling is difficult to remove, such as the CaCO3 fouling, silicon fouling(H2O2 bleaching, formation at the time of Na2SiO3 as oxygen bleaching stabilizer), in some time, we need to beat and repeating washing to remove the fouling. Some fouling, for example, dacron oligomer is difficult to move using acid and alkali. The fouling is mainly from the impurities by untreated water, equipment, processing of fiber (such as cotton pectin) impurities and dyes and chemicals (such as sodium sulfate, sodium carbonate). Due to the presence of these substances, the formation of insoluble matter de...

At present, the effective methods that can prevent the  amino silicone oil  causing yellowing are as follows: (1)Dongguan Hongqi chemical Co., Ltd introduce high sterically hindered secondary amine into PDMS, the softness and the yellowing of the fabric become improved compared with the biohydrogen group modified amino silicone oil. (2)Hongqi chemical launch all kinds of oil agent with Hongqi as the brand name, which improves the fabrics property in softness and yellowing. (3)Silicone oil cyclamate possesses good anti-yellowing property.  Diallyl cyclamate and SiMB react under the catalyst platinum will produce cyclamate siloxane. (4)Piperazine modified amino silicone oil is made by introducing the ring diamino into PDMS molecule, which will prevent the yellowing of fabric. (5)The hydrosilation addition reaction process of polyhydrosiloxanes and α-olefine epoxy compound will produce epoxy silicone oil, which will react with organic amine ammonia and produce new...

In general conditions,  according to conventional requirements, different fabrics has different requirement on  amino silicone oil  as follows: ① Pure cotton, blended knitting fabric and woven fabric mainly requires soft hand feeling, and the 0.6 ammonia value of amino silicone oil should be chose. ② Dacron fabric requires smooth hand feeling, the 0.3 amino value of silicone oil should be chosen. ③Real silk fabric and woven fabrics requires smooth hand feeling, and have high requirement on glossiness. And the 0.3 amino value of silicone oil should be chosen. And the mixture of smooths will increase the glossiness. ④ The wool and its blended fabric requires softness, smoothness and elasticity hand feeling with low glossiness change. So 0.6 amino value and 0.3 amino value amino silicone oil blended produce should be chosen. And in some time, the increase of smoothness agent will help to increase the glossiness and the elasticity. ⑤ Cashmere sweater and other cash...

Amino silicone oil  has four important parameters: ammonia value, viscosity, reactivity and particle size. These four parameters basically reflect the quality of amino silicone oil and it will greatly affect the style of the treated fabric, such as hand-feeling, whiteness, light color, and the complexity of silicone oil emulsion. I. Ammonia value Most of the properties, such as softness, smoothness, and fullness on the fabric are mostly caused by amino groups in polymers. The amino content can be expressed by an ammonia value, which refers to the consumption number of 1 normal concentration of hydrochloric acid required for neutralization of the 1G amino silicone oil. Therefore, the ammonia value is directly proportional to the mole percent of amino group in silicone oil. But the active hydrogen in the amino is easy to be oxidized and form chromophore, which will cause the fabric yellowing or slightly yellow light. For the same amino group, with the increase of the amino c...

Anti-static fabrics Anti-static fabric can be made of woven conductive fiber and fabric surface finishing method. By embedding conductive fibers (knit with metal wire) method can enhance the fabric's anti-static properties. and the effect is lasting. Meantime, it can improve the fabric hygroscopicity and antifouling properties; Fabric surface finishing method is the finishing of anti static resin of the synthetic fabric, the  anti static agents  covering the the surface of the fabric, increase the conductive properties of the fiber by moisture. Waterproof & moisture permeable fabric The development of waterproof and moisture permeable fabrics mainly consists of 3 methods: high-density weaving, fabric coating and microporous membrane laminating. Among them, PTFE waterproof moisture permeable and laminating are the most typical. Because PTFE porous film has the contact angle and the radius of the hole, it has the property of the water pressure and water vapor permeabili...

I. The mean of easy-care finishing Compared with chemical fiber, natural fiber has excellent moisture absorption, air permeability, and anti-static properties. It is an ideal material for clothing, but it is easy to wrinkle after washing and needs ironing. With the accelerating pace of modern life, people generally have no time to iron clothes, thus easy-care finishing has become one of the indispensable and important processes in the textile dyeing and finishing. The easy-care textile on the market mainly includes shirts and pants, uniforms and other clothing, and bed sheets, pillowcases, curtains, tablecloths and other household textiles. II. The causes of wrinkle of textiles Cellulose fibers are divided into crystalline and amorphous areas, and amorphous areas determine the softness of the fibers. Under the action of the external force (washing or wearing process), the fiber is bent and deformed, the inner part of the amorphous region is broken by hydrogen bonds, and a new hyd...

Good permeability:  The transmissivity of the silicone elastomer film to the nitrogen, oxygen, carbon dioxide and other gasses in the air is 30-50 times higher than natural rubber at room temperature. Good water repellency:  After silicone coating, the fabric does has good water repellency without being waterproof treatment, and the uncoated layer can still maintain good moisture absorption. Good weather resistance:  Due to the structural characteristics of the silicone molecular with an inorganic polymer, the coating agent can be a long term used under the environment of 250-300°C, and minus 50-60 °C. Silicone elastomer also has excellent resistance to ultraviolet radiation, radiation resistance, ozone resistance. It can be used in outdoor for 10 years. Excellent mechanical properties:  The tensile strength of silicone elastomer is about 100kg/cm at most, and the tensile strength and breaking strength of nylon fabric processed by   coating finishing...
