Polypropylene staple fiber with polypropylene resin as the main raw material, after melt spinning, drawing, curling, drying finalize cutting, packaging and other processes of color and colorless, specified number and length of fluffy fiber.

In fact, the texture of polypropylene staple fiber is very light. For example, its density is 0.90-0.92 g/cm, which is light among all chemical fibers. It is 20% lighter than nylon and 30% lighter than polyester, which is very good at this point. Polypropylene short fiber it has a high resistivity (7×10Ω.cm), small thermal conductivity, this is because it is compared with other chemical fibers, the electrical insulation and heat preservation of polypropylene is the best, but it is also very easy to produce static electricity when processing. The moisture absorption rate of PP polypropylene fiber was 0; Of course, its wear resistance is larger, the strength is higher; Good corrosion resistance, weak acid and weak alkali resistance; In addition, when it is used, it is mainly because of its good stability, so the organic solvent sticks to the clothes easy to clean up. PP polypropylene staple fibers can also be used as building materials.

The use of polypropylene staple fiber

1. Used in paper industry

The application of polypropylene staple fiber in the field of dry papermaking is mainly to produce puffed soft paper. Expanded soft paper, also known as dust-free paper, is a new type of disposable sanitary material. It can be made into high density dust-free paper absorbing core material, which can be used to meet the special needs of sanitary material with high absorption capacity and excellent liquid holding effect, and can also be made into low density absorbing core material for medical materials.

2. For nonwoven industry

Polypropylene staple fiber in the nonwoven industry, polypropylene staple fiber is used in the production of heat-bonded nonwovens because of its low thermal bonding temperature.

3. Used in construction industry

Polypropylene staple fiber is mainly used for reinforcing concrete in the construction industry.
