With regard to the introduction of pp yarns (also known as polypropylene yarns), let us start with the advantages of polypropylene. The more significant advantage is that the texture is light, and its density is only 0.91g/cm3, which is a lighter density among common chemical fibers, so the same weight of polypropylene can obtain a higher coverage area than other fibers. Polypropylene has high strength, good tensile strength, high initial modulus and excellent elasticity, so polypropylene has good abrasion resistance.

In addition, the wet strength of polypropylene is basically equal to dry strength, so it is an ideal material for making fishing nets and cables; hygroscopicity and dyeing properties are light and warm; almost no moisture absorption, but strong wicking ability, obvious moisture absorption and perspiration; polypropylene It has little hygroscopicity and almost no moisture absorption. The general moisture regain rate under atmospheric conditions is close to zero. In addition, polypropylene has good electrical insulation, but it is easy to generate static electricity during processing.

The pp yarn perfectly inherits all the advantages of polypropylene, which makes the role of pp yarn more and more, and the market is getting bigger and bigger.
