Demand for polypropylene high-strength yarn in markets around the world is on the rise. Due to its advantages of aging resistance, acid and alkali resistance, light weight, abrasion resistance, low thermal conductivity, corrosion resistance to seawater, non-hygroscopicity and high breaking strength, polypropylene high strength yarn is widely used in safety net belt, industrial harness, flexible container bag As a substitute for Polyester, Nylon, Polyester, Polyester, Polyester, Polyester, Polyester, Polyester, A new type of fiber ideal fiber material.

High strength polypropylene yarn is characterized by relative density, low melting point and glass transition temperature, high strength, acid and alkali resistance, high crystallinity, low moisture absorption rate, good chemical resistance and good mechanical properties.

Compared with polyester, acrylic, nylon, polypropylene high strength yarn has the advantages of simple raw material production and spinning process, short process route, low raw material and comprehensive energy consumption, low cost, no pollution and wide application. Because of its lower cost than other synthetic fibers, since the industrialization of high-strength polypropylene yarn has been rapid development.

Especially with the emphasis on the quality of the project, the cloth is made of polypropylene high-strength yarn braided geotextile, which is more suitable for the construction of highways, railways, airports, seawalls, drains, reservoirs, harbors and bridges, and its application will rapidly increase. The product does not need to cut off, cofferdam, dam drainage, and fast, high efficiency, investment, good quality, and other advantages, especially in the case of large load, woven geotextile non-woven geotextile Cloth has more unique. Use of its acid and alkali, corrosion resistance, high strength, non-absorbent, light weight, good stability, good filter stripping, etc., can be made of high-strength polypropylene filter cloth.

Today, with the continuous improvement of contemporary industrial technology and the continuous expansion of industrial textiles, polypropylene high-strength filaments are also widely used in more industrial fields due to their unique economic value and performance. Next, PP high-strength yarn will play a major role in a wide range of applications of synthetic fibers, the prospects are bright.
