Technical Field

The invention belongs to the technical field of textile auxiliary agents, and particularly relates to a softening agent and a preparation method thereof.

Background

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 feel of the two is soft.
