In the development process of the paper industry, material innovation is always an important factor to promote the progress of the industry. As a kind of synthetic fiber with excellent performance, polypropylene staple fiber has been widely used in the field of paper making by virtue of its unique advantages, and has become an important raw material for modern paper industry, which has brought significant changes and development opportunities for the industry.

Dry papermaking field: Key material for extruded soft paper production

In the field of dry papermaking, polypropylene short fiber is used to produce puffed soft paper, that is, dust-free paper, which is a new disposable sanitary material. Polypropylene staple fiber is an important raw material for the manufacture of high-density dust-free paper absorbing core material. The core material has strong absorption capacity and good liquid holding effect, and is widely used in the health products industry, such as high-end diapers, female hygiene products, etc., which can provide users with comfortable and efficient use experience. At the same time, the low-density absorption core material made of polypropylene staple fiber plays a role in the field of medical materials, such as wound dressings, surgical pads, etc. Its soft and dust-free characteristics help to reduce the irritation of the wound and reduce the risk of infection, which is a suitable choice for medical care.

Wet paper industry: an important element for improving paper quality

In wet paper making, the mixing of polypropylene staple fiber and plant fiber plays an important role in improving paper quality. By interweaving with plant fiber, polypropylene staple fiber can significantly improve the performance of paper, greatly improve the wet strength of paper, so that paper can still maintain good toughness in wet environment, not easy to break. This feature is particularly critical in the production of special paper with high wet strength requirements, such as filter paper, which is subject to certain pressure and humidity when filtering liquids, and the addition of polypropylene staple fibers ensures stable performance and extended service life of filter paper. In the production of tea bag paper, the improvement of wet strength ensures the integrity of the tea bag when it is soaked in hot water, providing consumers with convenient and hygienic tea brewing conditions.

In addition, polypropylene staple fiber can change the elastic modulus of the paper, give the paper a certain elasticity, make the paper more flexible in use, not easy to break, and improve its wear resistance. In paper applications such as wrapping paper and label paper that require frequent friction, the advantages of polypropylene staple fibers are reflected, effectively improving the durability and appearance quality of the product.

Paper recycling and recycling: a driving force for sustainable development

In the context of global advocacy of sustainable development, paper recycling and recycling have become the focus of the paper industry. Polypropylene staple fiber plays an active role in this field, providing help for the green development of the industry. Usually, after repeated use of pulp 5-6 times, its fastness and tearing strength will gradually reduce, affecting the quality and performance of the paper. The addition of ultra-short synthetic fibers, especially polypropylene staple fibers, effectively solved this problem. It can maintain the fastness and strength of the paper in the pulp recycling process, ensure the stable quality of the recycled paper, and also improve the drying speed and unit production capacity of the paper, reduce the energy consumption in the production process, shorten the production cycle, and thus reduce the production cost. This multi-faceted positive impact makes polypropylene staple fibers an important part of paper recycling and recycling, and promotes the development of the paper industry in a more environmentally friendly and efficient direction.

In summary, polypropylene staple fiber performs well in many fields such as dry paper making, wet paper making and paper recycling, and has become an important material widely used in the paper industry. Its application improves the quality and performance of paper, meets the diversified market demand, and strongly supports the sustainable development of paper industry. With the advancement of science and technology and the development of the industry, polypropylene staple fiber is expected to play a greater role in the field of paper making and create more value.
