Technical Field

The invention relates to a softening agent preparation technology.

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.

Soft finishing is an important after-finishing process in printing and dyeing processing. During the processing of the textile, the hand feeling of the textile becomes rough after being treated for many times, and the common synthetic fiber fabrics are worse, especially the superfine fiber fabrics. In order to make the fabric have soft, smooth and comfortable hand feeling, the fabric needs to be finished, and the finishing is widely performed by using a softening agent at present. In addition, a large amount of softening agents are used in the processes of spinning chemical fibers, spinning various fibers, weaving various fibers and the like, and the phenomena of scratch, strip defect and the like are easily caused because the mutual friction between fabrics and between the fabrics and equipment is increased along with the large amount of use of high-speed and small bath ratio modes in textile processing. The use of a softening agent allows the fibers themselves to have a soft smoothness compatible with the processing conditions to avoid damage.
