Polypropylene non-woven fabric, also known as PP or polypropylene non-woven fabric
Raw material: Polypropylene fiber (synthetic fiber spun from isotactic polypropylene obtained from propylene polymerization)
1. Lightweight, it is the lightest among all chemical fibers.
2. High strength, good elasticity, wear resistance, corrosion resistance, good wear resistance and resilience, similar in strength to polyester, with a much higher rebound rate than polyester; Chemical resistance is superior to general fibers.
3. Polypropylene fiber has high electrical resistivity (7 × 1019 Ω. cm) and low thermal conductivity. Compared with other chemical fibers, polypropylene fiber has the best electrical insulation and insulation properties, but is prone to static electricity during processing.
4. It has poor heat resistance and aging resistance, but its anti-aging properties can be improved by adding anti-aging agents during spinning.
5. It has poor hygroscopicity and dyeability. Most colored polypropylene is produced by dyeing before spinning. Dope coloring, fiber modification, and fuel complexing agent can be blended before melt spinning.
1. Used for disposable sanitary products, such as sanitary napkins, surgical gowns, hats, masks, bedding, diaper fabrics, etc. Women’s sanitary napkins, disposable baby and adult diapers have now become common products that people consume every day.
2. Polypropylene fibers that have been chemically or physically modified can have multiple functions such as exchange, heat storage, conductivity, antibacterial, odor elimination, ultraviolet shielding, adsorption, desquamation, isolation selection, agglutination, etc., and will become artificial kidneys, Important materials in many medical fields such as artificial lungs, artificial blood vessels, surgical threads and absorbent gauze.
3. There is a growing market for labor protection clothing, disposable masks, hats, surgical gowns, bedsheets, pillowcases, mattress materials, etc.
