As we all know, polypropylene staple fiber is widely used in the industry field. Polypropylene staple fiber is widely used in papermaking (paper fiber), nonwoven and construction (engineering fiber) industry. Today, let's talk about the application of polypropylene staple fiber in papermaking (paper fiber), nonwoven and construction (engineering fiber) industry.

Polypropylene staple fiber is widely used as raw material for papermaking, and the annual demand for staple fiber is about 500t. While the domestic user in our country mainly uses the ultra-short fiber as the raw material of filtering, packaging, insulation, anti-counterfeiting and antibacterial paper, and the annual demand is at 600t.

Papermaking is divided into dry papermaking and wet papermaking.

First, the application of polypropylene 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 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 materials with high absorption capacity and excellent liquid holding effect, and can also be made into low density absorbing core material for medical materials.

Two, in the field of wet papermaking, polypropylene staple fiber is mainly used for mixed paper and plant fiber, in order to improve the quality of paper, improve the wet strength of paper, by changing the elastic modulus of paper, so that it has a certain elasticity, improve the wear resistance, mainly used in the production of filter paper, tea bag paper and other special paper with high wet strength requirements.

In addition, polypropylene staple fiber can also be used for paper recycling and regeneration. Generally, pulp can be reused 5~6 times, but the fastness and tear strength of the paper will decrease with the increase of reuse times. The addition of ultra-short synthetic fibers can not only solve the problem of declining fastness and strength during the reuse process of pulp, but also improve the drying speed and unit production capacity of the paper, thus reducing the production cost.

Our company mainly produces polypropylene staple fiber and polyester staple fiber: specifications 1.5D to 200D, length 5-150mm, the product color is complete, rich variety, support color map or sample customization, fully meet your individual needs. With an annual output of 20000 tons, our company's polypropylene staple fiber and polyester staple fiber products are mainly used in: health non-woven fabric, spunky non-woven fabric, needled carpet, electric blanket fabric, filter cloth, geotextile, automobile decorative cloth, clothing shirt, artificial fur, wool, yarn spinning and other fields.
