The characteristics of polypropylene fiber

1. The characteristics of polypropylene fiber fabrics. Polypropylene is the lighter fiber among all clothing fibers. It is a fiber that can float on water (specific gravity is about 0.91g/cm3), but its strength is very good, so it has been widely used in clothing. application. The characteristics of polypropylene fabrics are as follows: ⑴Polypropylene is a light-clothing fabric, its weight is only 3/5 of cotton, so it is very suitable for winter clothing padding or ski clothing, mountaineering clothing and other fabrics, can also be used to make ropes, fishing nets , Filter cloth, etc. ⑵The moisture absorption quality of polypropylene fabric is small, and its moisture regain rate is regarded as 0%. Therefore, its clothing is known for its advantages such as quick-drying, refreshing, and non-shrinking. But the comfort is not good, and the dyeability is also poor. Since polypropylene film is easy to break in the direction perpendicular to the stretching, it is mostly used for wrapping ropes. ⑶ Polypropylene fabric has good strength and abrasion resistance, and the clothing is firm and durable. ⑷ Polypropylene fabric is corrosion-resistant, but not heat-resistant, light-resistant, and easy to age. ⑸ Polypropylene fiber fabric has good stability to inorganic acids and alkalis, but slightly less stable to organic solvents.

2. Polypropylene fiber fabric varieties Polypropylene fabrics include pure spinning, blending and interweaving. Among them, blended and interwoven fabrics are mostly matched with cotton fibers, such as polypropylene/cotton fine cloth, polypropylene/cotton assorted yarn and other varieties; while pure polypropylene fabrics are Take the pari velvet coat as a representative.

 ⑴Pali velvet overcoat is a wool-like fabric woven from polypropylene terry yarn dyed with dope. It has a unique woolen terry style, bright and beautiful color, light texture, warmth, and strong wool feeling. Its greater advantage is easy Wash and dry quickly, good quality and low price. Suitable for youth clothing and children's overcoats.

⑵C/Cotton Hemp Yarn is made of C/Cotton 65/35 blended yarn, which is strong and durable, has a crisp appearance and good dimensional stability. It is mostly used as military raincoats, mosquito nets, etc.

 ⑶Polypropylene/cotton muslin Polypropylene is the trade name of polypropylene fiber. It is a fiber made from propylene as a raw material through polymerization and melt spinning. Polypropylene officially began industrial production in 1957 and is a rising star among synthetic fibers. Because polypropylene fiber has the advantages of simple production process, low product price, high strength, and light relative density, polypropylene fiber has developed rapidly. At present, polypropylene is the fourth largest variety of synthetic fibers.
