What is polypropylene yarn?

Raw material of polypropylene yarn; about the introduction of polypropylene yarn, let's start with its biggest point. The biggest advantage is its light texture. Its density is only 0.91g/cm3, which is the lightest variety among common chemical fibers. Therefore, polypropylene fiber of the same weight can obtain a higher coverage area than other fibers. Strength and elongation Polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene fiber has good abrasion resistance; in addition, the wet strength of polypropylene fiber is basically equal to the dry strength, so it is an ideal material for making fishing nets and cables; it has light moisture absorption and dyeing properties and good warmth retention; almost no moisture absorption, but strong wicking ability. The effect of moisture absorption and perspiration is obvious; polypropylene fiber has very little moisture absorption, almost no moisture absorption, and the moisture regain rate under general atmospheric conditions is close to zero. In addition, polypropylene has good electrical insulation, but it is easy to generate static electricity during processing. Due to the low thermal conductivity of polypropylene, good warmth retention; high strength Polypropylene stretch yarn is second only to nylon in strength, but the price is only 1/3 of nylon; the fabric has stable dimensions, good abrasion resistance and good chemical stability.
