The fiber's length, thickness, whiteness, gloss and other properties can be adjusted during the production process, and it has the advantages of light resistance, wear resistance, easy washing and drying, no mildew, no insect bites, etc. With the progress of society, the chemical fiber industry has developed greatly, and the demand for chemical fiber products has also increased, thus putting forward higher requirements on the production equipment of the chemical fiber industry.

It is easy to break when the tension is too large. Utility Model Content
