Can polypropylene high-strength yarn be used instead of natural fiber?

Compared with natural fibers, in addition to excellent mechanical properties and chemical stability, polypropylene high-strength yarns have low equipment investment, cheap raw materials, and consume less energy, and have obvious technical and economic advantages. Therefore, sometimes polypropylene high-strength yarn can be used instead of natural fiber.

1. Polypropylene high-strength yarn has high strength

The strength of polypropylene high-strength yarn is comparable to that of polyester and nylon industrial yarns. The tensile elasticity is single times that of ordinary polypropylene yarn, and it is exactly the same in wet and dry conditions. The cost is only about 15% higher than ordinary silk.

2. Polypropylene high-strength yarn has low density and low moisture absorption

Polypropylene is the less dense of all synthetic fibers at present, and its density is only 66% of polyester and 80% of nylon. If calculated by volume, the volume of polypropylene high-strength yarn with the same weight is 1.5 times that of polyester and 1.25 times that of nylon. If the price and density of the silk are considered at the same time, finished products of the same thickness and weight are produced, and polypropylene high-strength silk is used as the raw material. The raw material cost is much lower than that of polyester industrial yarn and Jinkun industrial yarn. Due to its low hygroscopicity, polypropylene is especially suitable for marine products and other products that require non-hygroscopicity.

3. Polypropylene high-strength yarn is wear-resistant

The abrasion resistance of polypropylene fiber is single in the dry or wet state, the flat abrasion resistance is close to that of nylon, and the bending resistance is slightly worse. Therefore, polypropylene high-strength yarn is very wear-resistant.

4. Polypropylene high-strength yarn has low thermal conductivity

The thermal conductivity of polypropylene high-strength yarn is 0.1~0.3J/(m·s·k), and the heat preservation is good.

5. Polypropylene high-strength yarn has good stability to chemicals

Since there are no active genes in the molecular structure of polypropylene, polypropylene high-strength yarns are very stable to acids, alkalis and other chemicals.

6. Polypropylene high-strength yarn is resistant to microorganisms

Polypropylene high-strength yarn is not eroded by insects and bacteria, and is resistant to mildew.

7. Polypropylene high-strength yarn has poor thermal stability

When the use temperature of polypropylene high-strength yarn exceeds 120℃, the fiber strength will decrease significantly.

8. UV stability of polypropylene high-strength yarn

The light resistance of polypropylene fiber itself is not good. At present, the UV stability problem of polypropylene high-strength filaments has been solved by adding light stabilizers.

With so many excellent properties of polypropylene high-strength yarn, it can be used instead of natural fiber in a certain way.
