How important is polypropylene spinning finish to polypropylene fiber?

Polypropylene spinning finish is generally composed of smoothing agent, antistatic agent, emulsifier and auxiliary components. The quality of polypropylene spinning finish directly determines the quality of polypropylene fiber produced.

The main function of polypropylene spinning finish is to adjust the friction properties of chemical fibers, prevent or eliminate static electricity accumulation, and endow the fibers with smooth, bundling, antistatic, and soft properties, so that polypropylene fibers can smoothly pass through spinning, stretching, texturing, and spinning. Yarn and weaving processes.
