The polypropylene longitudinal smooth is straight, the cross section is circular and other shapes, polypropylene has waxy hand feeling and gloss, dyeing is difficult, generally staining. Polypropylene is a fiber developed from later-lateral development. Its relative density is the smallest in common textile fibers. It is also light than water, which is 3/5 of cotton fibers. It is suitable for making water sports clothing common product name with Her Herculan and Hostalen, etc. Two filaments and short fibers. The strength, elasticity and wear resistance of polypropylene are better, and the fabric is not easy to wrinkle, so the durability is durable, the size of the garment is more stable. Filament is often used to make imitation silk fabrics and knitted fabrics; short fiber dimensions are cotton, used for carpets or nonwoven fabrics. The moisture absorption of polypropylene is poor, and it is easy to static and started during use. The fine and polypropylene has a strong core suction, water vapor can be excluded by capillary in the fibers. After making clothing, the comfort of clothing is better, especially ultra-fine fibers, due to increased surface area, can transfer sweat faster, and maintain comfort.

The melting point of polypropylene staple fibes (165 ~ 173 ° C), poor light, thermal stability, sooth polypropylene fiber heat resistance, poor aging resistance, usually take the addition of heat stabilizers and anti-aging agents to improve their properties. Its hygroscopicity and dyeness are the worst in the synthetic fibers, and the slot margin is less than 0.03%, and the ordinary dyes cannot be colored, and therefore, in the spinning, a quantity of coloring masterbills are added to the raw material polypropylene. Coloration.
