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 important finishing process in printing and dyeing. Textiles, in the processing of repeated treatment, will become rough and the hand feeling become coarse, the general synthetic fiber fabric is worse, especially microfiber fabric. In order to make the fabric soft, smooth, comfortable feel, it's required to be finished with softening agents, the widely applied softeners for textile. In addition, in the chemical fiber spinning, all kinds of fiber spinning, weaving and other processes, a large number of softening agent has been used, which is because that with the textile processing in the high speed and small bath ratio of large-scale use, fabric and the friction between the fabric and equipment increased, easy to produce abrasions, flaws and so on. The use of softening agent can make the fiber itself with the processing conditions to adapt to the softness and smoothness to avoid damage. Therefore, fabric softener is an important textile auxiliaries.The advantages of softening agent in textile:
4. In addition, Softener is also used in the process of raising, wrinkle-proof, sewing and winding of silk.Softeners for textile, as the conventional textile finishing agents of fabric, the application has been used for more than half a century, and is developing very rapidly, from the earliest surfactant softener to polymer softener, and from polymer polyethylene wax to silicone polymers, the development of hydroxyl-terminated poly, hydrophilic silicone softener, amino polysiloxane emulsion, amino polysiloxane microemulsion, low yellowing amino-modified silicone softener, and hydrophilic Amino silicone softener and ultra smooth amino-modified polysiloxane. A variety of new fibers such as ultra-fine fiber have been widely used, with the increasing awareness of environmental protection, all kinds of softener and its main components have been further improved.
