We all know that polypropylene staple fiber is used in a wide range of industries, polypropylene staple fiber in paper (paper fiber), nonwovens and construction (engineering fiber) industry is widely used.

Polypropylene staple fiber is widely used as a raw material for paper making, and the annual demand for short fiber is about 500t. China's domestic users mainly use ultra-short fiber as raw materials for filtration, packaging, insulation, anti-counterfeiting, antibacterial and other papers, and the annual demand is about 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. Extruded soft paper, also known as dust-free paper, is a new type of disposable sanitary material, which can be made into high-density dust-free paper absorption core material, 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 absorption core material for medical materials.

Second, in the field of wet paper making, polypropylene short fiber is mainly used for mixed paper and plant fiber 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 wear resistance, mainly used in the production of special paper such as 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 recycling. General pulp can be reused 5 to 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 fastness and strength decline in the process of pulp reuse, but also improve the drying speed and unit production capacity of the paper, thereby reducing the production cost.
