Is it troublesome to degrease for chemical fiber fabrics? Is it inefficient or environmentally-friendly?

The moisture regain and permittivity of chemical fibers (as polyester, vinylon, acrylic fiber and nylon, etc.) are lower. But friction coefficient is higher. The constant friction during spinning and weaving creates a lot of static electricity. It is necessary to prevent and eliminate the accumulation of static electricity, and at the same time to impart the fiber smoothness and softness, so that the processing can go well. Therefore, there must use spinning oil.

With the development of variety of chemical fiber and the improvement of chemical fiber spinning oil and weaving process, the greasy dirt remaining on chemical fiber fabrics (as spinning oil and weaving oil) has changed a lot. The spinning oil and weaving oil used by each factory are different. In recent years, textile machinery has developed rapidly. The dosage of oil increases accordingly. Some factories have pursued big weight of chemical fiber knitted fabrics one-sidedly, so they have increased dosage of oil. In addition, some chemical fiber fabrics are placed outdoors, covered in a lot of dirt and oil contamination. All these have brought certain difficulties to the degreasing process in pretreatment before dyeing and finishing.
