What are the characteristics of polypropylene high-strength yarns, do you know?
Polypropylene high-strength yarn has many years of development history. Nowadays, it has been widely used. This is also because polypropylene high-strength yarn has outstanding characteristics.
Outstanding features of polypropylene high-strength yarn:
1. It has a very high tensile strength, up to 70.6cN/tex (8g/d), which is almost a single time of ordinary polypropylene yarn.
2. The density of polypropylene high-strength yarn is 0.91, which is the smaller of synthetic fibers, which is lighter than water.
3. The thermal conductivity is 0.1～0.3J/m·s·K, such a low value, so the heat preservation performance is very good.
4. There is almost no hygroscopicity, which makes it difficult to dye, but it can be colored with masterbatch stock solution. The moisture absorption rate is zero, so the wet strength is equal to the dry strength, and the strength of the product in water will not decrease.
5. It has excellent chemical resistance. Compared with the chemical resistance, acid resistance and alkali resistance of various fibers, polypropylene fiber is superior to polyester, nylon, acrylic, vinylon, etc., except that it is not as good as PTFE fiber.
6. It is not corroded by insects and bacteria, and has outstanding resistance to mildew and microorganisms.
7. The melting point of polypropylene high-strength yarn is only 176 ℃, so heat resistance and thermal stability are poor. Relatively speaking, this is the shortcoming of polypropylene. However, due to the thermoplastic nature of polypropylene high-strength yarn, it is below 130°C, and the measured strength increases after the temperature rises.
8. Abrasion resistance is also a single sample in wet and dry state, flat abrasion resistance is close to nylon, and bending resistance is slightly worse.
9. Polypropylene fiber has poor light resistance and is easy to age, but the light resistance can fully meet the requirements after adding light stabilizers.
The above are the nine outstanding features of polypropylene high-strength yarn.
Xuzhou Heping Chemical Fiber Co., Ltd. is located in Xuzhou, Jiangsu. For many years, it has focused on the research and development and production of polypropylene high-strength yarn. The polypropylene high-strength yarn produced by it has many excellent properties such as light weight, high strength, anti-aging, acid and alkali resistance, which also makes polypropylene high-strength Silk can be used in all aspects of our lives. Heping chemical fiber polypropylene high-strength yarn is supplied by manufacturers, with a complete range of products and high-quality after-sales service. Users can purchase with confidence. Heping Chemical Fiber also has high-quality polypropylene industrial yarn, polypropylene high-strength yarn, high-strength polypropylene network yarn, polypropylene high-strength yarn, high-strength polypropylene yarn and split film industrial yarn.
