What is the seemingly simple polypropylene staple fiber production process?

The polypropylene staple fiber process seems simple and convenient, but in fact, it is a big impact on its production of finished products, such as the pretextile of polypropylene.

Dellarous short fibers are too large, which will bring a lot of harm. And in the blending, the strength of the yarn will also affect.

The strength of the yarn after the blending, such as the quality indicator of pure polypropylene, 50% cotton blend indicator 1950, polypropylene 50% cotton blend indicator 2193, 215 cotton quality index 2336. It can be seen from the above data, and the pure splicing gauze is high, which is much higher than the cotton, but it is not as good as cotton, which is not as good as cotton. Although it may be related to the unevenness of the polypropylene staple fiber and cotton. Decanpropylene short fiber is difficult to control the length, so it is also a comparative test manufacturer than a simple step.

The appearance of polypropylene staple fibers seems to be a cotton, soft and has certain elasticity, polypropylene short fiber is large, it is easy to control in production, and the elongation will exceed 60%, which except for its polypropylene macromolecule In addition to structural factors, it may also be inadequate during the production process.

Because the filament is not uniform, improve the tensile ratio is easy to wrap the roller, or sometimes retransmond after retreat. In production, the retreat between the second stage and the third stretching machine is often found in the production, and the three five rollers are reversed. After the orientation, the fiber stress is large and retractable. These can be improved by tension thermal setting or proper heat treatment.
