The invention belongs to the technical field of dyes and chemicals, and particularly relates to a washing-resistant softening agent for nylon fabrics, and a preparation method and a use method thereof.
Background
Chinlon, commonly known as nylon, is an early synthetic fiber in the world. The nylon fiber has the characteristics of good wear resistance, high rebound resilience, excellent dyeing performance 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 less hydrophilic groups, poor hygroscopicity and poor fabric softness, so that the nylon fabric has poor hand feeling, and the application range of the nylon fabric is limited. Although the nylon fabric is finished by using a common softening agent in a factory to obtain a softening effect, the nylon fabric is difficult to obtain a durable softening effect.
Amino silicone oil and ternary block silicone oil are used as a softening agent, so that the softening effect is good, the fluffy and smooth effects are good, and the softening agent can be used as a softening agent for fibers such as cotton, terylene and chinlon, but the reactive groups on the surface of the chinlon fiber are few, and the softening agent 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 durability of the softening agent is poor.
