High-strength polypropylene fiber polypropylene fibers belong. Polypropylene fiber is neat and orderly arranged highly isotactic polypropylene polymer formed, and a high degree of crystallinity. This structure makes high-strength fiber wire has the following outstanding features in its performance:
High-strength fiber wire salient features:
1. has a very high tensile strength, up 70.6cN / tex (8g / d), which is almost double the ordinary polypropylene fiber.
2. Its density is the smallest synthetic 0.91, lighter than water.
3. Thermal conductivity of 0.1 ~ 0.3J / m · s · K, such a low value, it is a very good insulation properties.
4. virtually no moisture absorption, resulting in difficult to dye, but may be liquid color masterbatches. Moisture absorption rate is zero so wet strength equal to dry strength, product strength will not fall in the water.
5. has excellent chemical resistance, and a variety of fiber resistance, acid and alkali resistance were compared, except not as good as PTFE fiber polypropylene fiber, but better than polyester, nylon, acrylic fibers, polyvinyl alcohol and the like.
6. From the insect, bacterial attack, mildew resistant, outstanding resistance to microbial properties.
7. Its melting point is only 176 ℃, so the heat resistance, thermal stability of poor performance, relatively speaking, that is where the polypropylene deficiencies. But because of its thermoplastic properties it below 130 ℃, the measured temperature rise after strong but somewhat increased.
8. wear is as wet and dry, resistant grinding performance approaching nylon, wear-resistant curved slightly worse performance.
9. Polypropylene poor light, easy to aging, but after adding a light stabilizer light performance fully meet the requirements.
In short, high-strength polypropylene fiber excellent mechanical properties of the fibers belong, it is an important industrial textile fiber material.
High-strength fiber yarn are to its high tensile strength and impact strength to become very competitive in the field of industrial fiber materials, more and more widely used for those who have special physical properties is required.
High-strength polypropylene fiber can be widely used in the production of the following products:
1. The Ropes
2. With Class
3. Filter cloth
4. Sewing
5. canvas, covered cloth
6. geotextile
High-strength polypropylene fiber is gradually occupied as some of the textiles market, and hopefully expand their markets. Welcome to the Fiber Co., Ltd., Jiangsu Sisiyuan purchase!
