Technical Field

Background

With the rapid development of social economy and improvement of living standard of people in China, new requirements are made on wearing clothes, and the fabric is not only required to be moisture-absorbing, breathable and comfortable to wear, but also required to be soft, smooth and elegant. Softening finishes are in this situation. Softeners are a class of chemicals that change the static and dynamic coefficients of friction of the fibers. When the static friction coefficient is changed, the hand feeling is smooth and easy to move on the fiber or fabric; when the coefficient of dynamic friction is changed, the fine structures between the fibers tend to move relative to each other, that is, the fibers or the fabric tend to be deformed. The combined feeling of the two is soft, and the performance of the two directly determines the softness and the wearing comfort of the fabric.

At present, the most common softening finishing agent is amino silicone oil softening agent, and because amino can interact with hydroxyl, carboxyl and the like on the surface of fabric, siloxane can be attached to the surface of the fabric directionally, so that excellent hand feeling can be generated, the friction coefficient between fabric fibers is reduced, and a good softening finishing effect is achieved. However, there are some problems in use, amino silicone oil often does not have self-dispersing property, and after the amino silicone oil emulsion is prepared, oil floating or roll sticking phenomenon is easy to occur in storage and use. Meanwhile, the hydrophilicity of the fabric treated by the common amino silicone oil emulsion is reduced, so that the wearing comfort of the treated fabric is influenced. In addition, the fabric may be yellowed by high temperature or ultraviolet light irradiation.

Therefore, the development of new fabric softening finishing agents with excellent performance is a hot topic of research in the industry at present.
