Non-woven fabric manufacturers analyze how polypropylene PP non-woven fabric resists aging

Polypropylene non-woven fabric is also called PP non-woven fabric. Polypropylene is a raw material used in the manufacturing process of non-woven fabrics. The application of PP non-woven fabrics in life is very common, such as lock cups, many of which are PP and polypropylene. of.　　PP non-woven fabric is a new type of fiber structure product with soft, breathable and flat structure. It has the characteristics of short process flow, high production efficiency, significant economic benefits, rich product variety and wide application range. The raw material used for PP non-woven fabric is polypropylene fiber (PP fiber), which is the most total fiber in the production of non-woven fabric. Compared with other fibers, PP fiber has lighter specific gravity, higher strength, better abrasion resistance, good elastic recovery, no ball, acid and alkali resistance, chemical resistance is better than most other fibers, and has good antimicrobial performance. Not moldy, not moth and so on. PP non-woven fabric products are widely used in various fields of filtration, medical treatment, sanitation, health care, industry, agriculture, civil engineering, construction, home decoration and life.　　 Polypropylene is a very common raw material at present, and it is also a very important raw material for polymer fiber. Nearly 94% of spunbond and meltblown fabrics in my country are polypropylene. In the fields of medical treatment, sanitation and health care, the application of polypropylene non-woven fabrics accounts for 50% of the total non-woven fabrics. Polypropylene fiber has extremely low density (0.91g/cm3); low moisture content (u003c0.1%); good chemical resistance (acid, alkali, solvent); mildew, corrosion, mothproof, antibacterial; good Thermal insulation, heat preservation, insulation performance; high stiffness, good tensile strength (4.5 ~ 7.5cN/dtex); good fatigue resistance, abrasion resistance; temperature resistance is 120 ℃, melting point is 165 ℃; easy to regenerate Use and other performance. These characteristics make polypropylene fiber different from other synthetic fibers in two major ways: First, its low moisture absorption, which makes polypropylene fiber have excellent stain resistance and almost the same dry and wet characteristics; second It has the smallest density of all fibers, which makes it have good coverage under the same weight condition. As the thermal conductivity of polypropylene is the lowest among all fibers, its thermal insulation effect is better than wool, and its fiber not only has a lower density, but also has a larger coverage area. It can be used as a filler for home and car interiors and thermal flocks. Sheet materials, sound-absorbing and heat-insulating materials, etc.　　On the other hand, polypropylene does not react with general chemical reagents and has strong chemical resistance. Polypropylene non-woven fabrics can be used to make geotextiles, lead-acid battery diaphragms, filter materials, etc. Since there are no active groups in the main chain of the polypropylene fine fiber, the material itself is not easy to be corroded by bacteria and molds, and it has good hygiene performance when it comes in contact with human skin. Therefore, it can be widely used in the medical and health fields. . In addition, the lipophilic chain structure of polypropylene and the internal capillary structure formed by the transformation of crystals during the post-stretching of the fiber make its products have strong oil absorption and can be used to produce oil-absorbing felt materials.　　PP non-woven fabric manufacturer Quanzhou Non-woven Fabric Co., Ltd. focuses on the production of non-woven fabrics and the production of various non-woven products, non-woven bags, etc. The main products are polypropylene non-woven fabrics, coated non-woven fabrics, flame-retardant non-woven fabrics, PP non-woven fabrics, etc. The non-woven fabrics are of good quality and welcome to buy!
