Abstract: The performance of UHMWPE staple fiber and yarn was introduced in this paper. UHMWPE staple fiber can be used to spin various yarns, and also can be used as building reinforcement materials.The breaking strength of UHMWPE yarn is above 8 cN/dtex. With excellent abrasion-resistance and cutresistance performance, UHMWPE yarn can meet the requirements of some special fields, thus has a great market potential.

Key words: UHMWPE; staple fiber; yarn; performance
