Silicone quaternary ammonium salts can be used in the hydrophilic finishing of fabrics, widely imparting good water absorption, sweat absorption, softness, smoothness, resilience, anti-static properties, and non-toxic and harmless to fabrics. It is a highly efficient, safe, multi- Functional soft finishing agent. In addition to being used for antibacterial and soft finishing of fabrics, silicone quaternary ammonium salts can also be used on the surface of other materials. For example, the appropriate addition of silicone quaternary ammonium salt to wood, leather, non-woven fabrics, polyurethane, rubber, man-made fibers, synthetic fibers and various silicate surface coatings greatly enhances the antibacterial and antifungal effect; in leather fatliquor , Adding silicon ammonium chloride to the finishing agent, in addition to increasing the flexibility and firmness of the conjunctiva, the anti-mold effect is particularly outstanding; a certain amount of silicon ammonium chloride is added to the corrosion protection coating on the bottom of the ship. In addition to the corrosion inhibition function, it can also greatly improve the effectiveness of preventing the adhesion of algae and other organisms, maintain the ship chain, and extend the maintenance cycle of the ship.

Textile softener refers to a textile auxiliaries that can be adsorbed on the surface of textile fibers and make the fibers smooth, so as to change the hand feeling and make the product more comfortable. At present, there are thousands of types of softeners developed on the market, and most of them are surfactant-type softeners, reactive softeners, and silicone softeners. Among them, silicone softener is a kind of softener with superior performance, outstanding effect and wide application. Such softeners are emulsions or microemulsions of polysiloxane and its derivatives, which not only give the fabric a soft and smooth hand feel, but also provide good air permeability, surface gloss, wear resistance, and comfortable wearing characteristics, but also give the fabric repellency. Water and oil repellent, UV resistance and other functions; in addition, this kind of material is non-toxic and harmless, friendly to the human body and the environment, and low in cost. It is suitable for the finishing of different textiles (natural fiber, synthetic fiber, blended fiber, etc.), and has broad application prospects .
The development history of textile softener
Silicone softener originated in the 1950s, and its development has gone through four stages.
The first generation of silicone softener: The mechanical emulsification method is used to emulsify dimethyl silicone oil, but because the silicone oil itself does not contain active groups, it is not fast enough to bond with the fabric and is not washable. The effect of single use is not ideal, so it is rarely used as a softening agent now, but dimethyl silicone oil emulsion is still widely used in other fields, such as: shampoo softener, mold release agent, etc.; hydroxy silicone oil, silicone with hydroxy head Emulsion, under the action of metal catalysis, the softener can form network cross-links on the surface of the fabric, enhancing the washing resistance.
