Nylon, commonly known as nylon, is a synthetic fiber that has emerged earlier in the world. The nylon fiber has the characteristics of good wear resistance, high rebound resilience, excellent dyeing property and the like, always occupies an important position in the clothing industry, and is mainly used for manufacturing underwear, sports coats, various socks and the like. However, the nylon fiber has fewer hydrophilic groups, poor hygroscopicity and poor softness, so that the nylon fabric has poor hand feeling, and the application range of the nylon fabric is limited. Although factories finish nylon fabrics with general softeners to obtain a softening effect, it is difficult to obtain a durable softening effect.
The amino silicone oil and the ternary block silicone oil are more applied as the softener, so that the softener has better softening effect and better fluffy and smooth waxy effect, can be used as the softener for cotton, terylene, chinlon and other fibers, but the softener has fewer surface reactive groups, is only adsorbed on the surface of the fiber, and is easy to fall off from the fabric under the condition of washing, so that the softener has poor durability.
