First understand what is polypropylene staple fiber. polypropylene staple fiber is a short fiber made by melt spinning, drawing, crimping, heat setting and cutting of polypropylene PP as raw material.

Secondly, it is clear which superior properties of polypropylene staple fiber. polypropylene staple fiber has superior moisture permeability and fast drying property, good combability and spinning performance, and can produce soft and tough fabrics. The fabric is light in weight, good in warmth, delicate in hand, comfortable to use, acid and alkali resistant. At the same time, it has the ability to dissolve quickly, good filling and sound insulation.

Due to its unique properties, polypropylene staple fiber can be produced in various types: cotton (textile), wool (non-woven), color, flame retardant, far infrared, hydrophilic and other types of fibers.

In fact, polypropylene staple fiber may have some problems in production. Today, let Qinfeng Xiaobian take a look at some of the problems and solutions that may exist in the production process of polypropylene staple fiber:

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

2, the 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 too large and the strength is low. This is due to the addition of the modified component, which is also related to the unreasonable spinning process. The elongation at break is too large to affect the yarn quality. The spinning process should also be carefully regulated.

4. From the perspective of post-spinning processing, there are no problems such as tangled cylinders, difficult combing and clearing traffic jams, indicating that the number of short fiber crimps and antistatic properties are reasonable. In addition, from the viewpoint of post-processing and spinning, it is also feasible to appropriately reduce the amount of antistatic component added by using a lower oil content than conventional spinning or simply using the dye to eliminate static electricity.

5, in the anti-static dyeable polypropylene short fiber finishing process, boiling dyeing is appropriate, to avoid high temperature treatment. After dyeing, the dyeing fastness of polypropylene staple fiber will be greatly improved.
