The problems and solutions of the scale production of polypropylene short fibers are:

1. There will be more defects in the early days, which can be solved gradually by adjusting the cooler cooling process parameters.

2. The accessories cannot be added at one time, but the mixture is demolished pre-spinning.

3. From the first-time short fiber test indicator, the elongation of the modified fibers is large and the strength is low, which is due to the addition of the modified component, and is also related to the spinning process is not reasonable. Long-term will affect the quality of the yarn, so it should also be carefully regulated from the textile process.

4. From the perspective of post-spinning, there is no entanglement of tin, combed difficulties and clear flowers, etc., indicating that the number of short fiber curls, antistatic resistance is reasonable. In addition, from the angle of post-processing and spinning, it is also possible to use its oil-removal angle than the hydrostatic oil ratio of conventional spinning to eliminate static electricity.

5. In the process of anti-static polypropylene, boiling is suitable, avoiding high temperature treatment. After dyeing, it will be greatly improved after a polypropylene short fiber dyeness.

The polypropylene short fiber is made of polypropylene resin as the main raw material, which is made into color and colorless, defined, defined, and the length of fluffy fibers.

polypropylene short fiber product performance:

1. Have superior humidification, flexibility, networked, and superior thermal bonds.

2. High strength, strong curl, light weight, low melting point, good surface permeability, acid base resistance, better than other fibers

polypropylene short fibers are mainly used in acupuncture carpets, automotive interiors, non-woven fabrics, ropes, decorative materials, health care products, etc.
