How to distinguish the quality of polypropylene high-strength yarn?

polypropylene high-strength yarn is widely used in safety mesh belts, flexible container bags, geotextiles and other fields because of its anti-aging, acid and alkali resistance, light weight, abrasion resistance, low thermal conductivity, seawater corrosion resistance, and no moisture absorption.

polypropylene high-strength yarn melts near the flame and is flammable. It burns slowly from the fire and emits black smoke. The upper end of the flame is yellow and the lower end is blue, emitting a smell of petroleum. The ashes after burning are hard round light yellow-brown particles, which are easily broken by hand twist.

Suining Tongjia Chemical Fiber Factory was founded in 2013, and its main products are 300D—3000D high-strength polypropylene filaments of various colors, polypropylene double-twisted yarns, polypropylene industrial yarns, high-strength polypropylene threads, etc.
