A detailed understanding of the polypropylene staple fiber in the production of the problems that may occur, can be very good to ensure the production of polypropylene staple fiber product quality.

First of all, we should have some understanding of polypropylene staple fiber products, polypropylene staple fiber is polypropylene PP as raw material through melt spinning, drafting, curling, heat setting, cut off a kind of short fiber.

Second polypropylene staple fiber has what superior performance. Polypropylene staple fiber has excellent moisture conductivity and fast drying, good carding and spinning properties, can produce soft and toughness of appropriate fabric, fabric light weight, good warmth, delicate feel, comfortable to wear, acid, alkali resistance. At the same time, it has fast melting, good filling and sound insulation performance.

These points should be paid attention to in the production process of polypropylene staple fiber.

1. There will be more defects in the early stage of production of polypropylene staple fiber, which can be solved by gradually adjusting the ring blower cooling process parameters.

2. Auxiliary materials can not be added at one time, but need to be mixed before spinning.

3. The elongation at break of the modified fiber is relatively large and the strength is low, which is caused by the addition of the modified components and is also related to the unreasonable spinning process. Too much elongation at break will affect the quality of the yarn, so it should be carefully controlled from the spinning process.

4. From the point of view of post-spinning processing, there are no problems such as tangling tin, carding difficulties and clearing jam, which indicates that the indexes such as crimp number and antistatic property of staple fiber are reasonable. In addition, from the point of view of post-processing and spinning, it is also feasible to reduce the amount of antistatic components by using lower oil content than conventional spinning or simply using dyeing ability to eliminate static electricity in spinning.

5. In the whole processing process of antistatic dyeing polypropylene staple fiber, boiling dyeing is appropriate to avoid high temperature treatment. After dyeing, the dyeing fastness of polypropylene short fiber will be greatly improved.
