HNZT ZTD series UHMWPE staple fiber, which has excellent spinnability and can be used in non-woven and cotton products, such as non-woven fabrics for clothing, filter non-woven fabrics, cut-resistant and stab-resistant non-woven fabrics, industrial non-woven fabrics and various textile blended yarns or sewing threads. It can effectively improve the mechanical properties, wear resistance and weather resistance of the fabrics. Meanwhile, due to the high degree of freedom, it can be evenly dispersed in various matrices, and it is suitable for making composite material reinforced skeletons and building reinforcement materials, such as fiber reinforced concrete, which can significantly improve the compression resistance of concrete Strength, flexural strength and split tensile strength.
