- Learn about the physical and chemical properties of polypropylene staple fibers! [7/21/2022]
- Learn about the physical and chemical properties of polypropylene staple fibers!1. Form The longitudinal surface of polypropylene fiber is straight and smooth, and the cross-section is circular.2. Density The biggest advantage of polypropylene is its light texture. Its density is only 0.91g/cm3, which is the lightest variety among common chemical fibers. Therefore, polypropylene of the same weight can obtain a higher coverage area than other fibers.3. Strong elongation Polypropylene has high strength, long elongation, high initial modulus and excellent elasticity. So polypropylene has good abrasion resistance. In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is an ideal material for making fishing nets and cables.4. Light hygroscopicity and dyeing properties, good warmth retention; almost no hygroscopicity, but strong heart absorbing ability, obvious moisture absorption and perspiration; polypropylene has very little hygroscopicity, almost no moisture absorption, and the moisture regain rate under general atmospheric conditions is close to zero . But it has a wicking effect, passing water vapour through the capillaries in the fabric, but does not have any absorption effect on its own. Polypropylene has poor dyeability and incomplete chromatogram, but it can be compensated by the method of dope dyeing.5. Acid and alkali resistance Polypropylene has good chemical corrosion resistance. Except for concentrated nitric acid and concentrated caustic soda, polypropylene has good resistance to acid and alkali, so it is suitable for use as filter material and packaging material.6. High strength The strength of polypropylene elastic yarn is second only to nylon, but the price is only 1/3 of nylon; the fabric is dimensionally stable, wear-resistant elasticity is also good, and chemical stability is good. However, it has poor thermal stability, is not resistant to sunlight, and is prone to aging and brittle damage. For this reason, anti-aging agents are often added to polypropylene fibers.Compared with polyamide fibers, polyester fibers, and viscose fibers, polypropylene staple fibers have their own advantages and characteristics. Polypropylene staple fibers use polypropylene resin as the main raw material. Colored and colorless fluffy fibers with specified denier and length in the process of packaging, packaging and other processes.So what are the high-quality properties of polypropylene staple fiber? Lightweight, its density is 0.9-0.92 g/cm3, the lightest among all synthetic fibers, it is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, and 40% lighter than viscose fiber; strength High (dry state and wet state), good abrasion resistance and resilience; anti-microbial, no mildew or moth; chemical resistance is also better than general synthetic fibers. In addition, compared with other synthetic fibers, polypropylene fiber has the best electrical insulation and warmth retention, it has a high electrical resistivity (7×1019 ohm·cm) and a small thermal conductivity. However, polypropylene staple fiber has a low melting point (165-173 °C) and poor light and thermal stability, so polypropylene fiber has poor heat resistance and aging resistance. Usually, heat stabilizers and anti-aging agents are added to improve its performance. Its hygroscopicity and dyeability are the worst among synthetic fibers, the moisture regain is less than 0.03%, and ordinary dyes can not make it color. coloring.......

- Learn about the application of polypropylene staple fiber in the paper industry! [7/14/2022]
- Polypropylene staple fiber is made of high-quality polypropylene raw materials that are melted at high temperature and spun into a spinning system composed of a spinneret and an external annular transverse blowing system, and then go through the processes of barrel dropping, drafting, crimping, and cutting.At present, polypropylene staple fibers are mainly used in papermaking (paper fibers), nonwovens and construction (engineering fibers). Today, the editor talks about the application of polypropylene staple fiber in the paper industry.Foreign polyester and polypropylene staple fibers are widely used as raw materials for papermaking, and the annual demand for staple fibers is about 500t; while domestic users in my country mainly use ultra-short fibers as raw materials for filtration, packaging, insulation, anti-counterfeiting, antibacterial and other paper. , the annual demand is about 600t.Papermaking is divided into dry papermaking and wet papermaking.1. The application of polypropylene in the field of dry papermaking is mainly to produce puffed soft paper. Puffed soft paper, also known as clean paper, is a new type of disposable sanitary material, which can be made into a high-density clean paper absorbing core material, which is used to meet special needs such as high absorption capacity and excellent liquid holding effect. It can also be made into a low-density absorbent core for medical materials.2. In the field of wet papermaking, polypropylene staple fibers are mainly used to make paper by mixing with plant fibers to improve the quality of the paper and increase the wet strength of the paper. By changing the elastic modulus of the paper, it has a certain elasticity and improves wear resistance. It is mainly used in the production of special paper with high wet strength requirements, such as filter paper and tea bag paper.In addition, polypropylene staple fibers can also be used for paper recycling and regeneration. Generally, pulp can be reused 5-6 times, but the fastness and tear strength of paper will decrease with the increase of reuse times. The addition of ultra-short synthetic fibers can not only solve the problem of decreased fastness and strength during pulp recycling, but also improve the drying speed and unit production capacity of paper, thereby reducing production costs.Taizhou Hailun Chemical Fiber Co., Ltd., formerly known as Taizhou Chenguang Synthetic Fiber Factory, was founded in 1995. It is a technical chemical fiber enterprise specializing in the research and development, production and sales of polypropylene staple fibers.
