1. Polypropylene fiber fabric characteristics Polypropylene fiber is the lightest of all clothing fibers, is floating on the water fiber (specific gravity of about 0.91g / cm3), but its strength is very good, so in clothing has been widespread application. Polypropylene fabric is characterized by: ⑴ polypropylene is one of light fabrics, and its weight is only 3/5 of cotton, so it is suitable for winter garments or cotton ski suits, mountaineering clothes and other fabrics, can also be used to make ropes, fishing nets , Filter cloth and so on. ⑵ polypropylene fabric moisture absorption is extremely small, the moisture regain is considered 0%, so its clothing to fast-drying, very cool, not shrinking and other advantages known. However, poor comfort, dyeing is also poor. As the polypropylene film is easy to break in the direction perpendicular to stretching, it is often used in the wrapping straps. ⑶ polypropylene fabric strength, wear resistance is very good, durable clothing fast. ⑷ polypropylene fabric corrosion-resistant, but not heat-resistant, light-resistant, easy to aging. ⑸ polypropylene fabric on the inorganic acid and alkali has a very good stability, slightly less stable organic solvents. 2. Polypropylene fiber fabric varieties of polypropylene fabric with pure spinning, blended and interwoven categories, of which, blended and interwoven fabric and cotton fibers with more, such as C / C fine cloth, C / C color linen yarn and other varieties; and pure polypropylene fabric then To Parigi coat it. ⑴Poly cashmere coat it to liquid dyeing polypropylene terry gauze woven wool-like fabric, has a unique wool terry style, bright color and beautiful, light texture and warm, hair feeling strong, its biggest advantage is easy to wash Quick-drying, inexpensive. Appropriate to do youth wear and children's coats and so on. ⑵ C / C color linen with C / 65/35 blended yarn woven, with strong durable, appearance crisp, good dimensional stability characteristics. Multi-purpose military raincoats, mosquito nets and so on. ⑶ C / C Polypropylene Polypropylene polypropylene fiber is the product name, which is made from propylene as raw materials by polymerization, melt spinning fiber. Polypropylene officially started industrial production in 1957, is a rising star in the synthetic fiber. As polypropylene has a simple production process, inexpensive products, high strength, the relative density of light advantages, so the rapid development of polypropylene. At present, polypropylene is the fourth largest variety of synthetic fibers.
