Principle of polypropylene staple fiber technology

The polymer is heated and fused into a spinning melt of a certain viscosity, which is continuously and evenly extruded to the spinneret by the spinning pump, pressed into a filament flow through the spinneret hole, and then cooled and solidified in air or water, and formed into a filament by drafting.

Polypropylene staple fiber process

Polypropylene staple fiber, direct spinning and slice spinning.

Direct spinning is the process of direct transfer of polymeric melt to spinning.

Slice spinning requires the polymer solution to be transported to spinning after casting, cutting and other preparation processes.

Polypropylene staple fiber is a univariate system that involves only the heat transfer between the polymer melt filament and the cooling medium.

Hubei Botao Synthetic Fiber Co., Ltd. has introduced a number of imported fiber production lines, with fixed assets of more than 300 million yuan, an annual output of 100,000 tons of polypropylene staple fiber, 20,000 tons of polyester staple fiber, 10,000 tons of composite fiber, and an annual output value of over 800 million yuan. Focusing on the field of synthetic fiber for more than 20 years, Botao synthetic fiber has obtained excellent market results and extensive honors with the mentality of excellence and integrity development.
