- This paper is concerned with transverse cut resistant properties of UHMWPE yarns by the methods of experimental and theoretical analysis. Rheological theory of fabric was applied to evaluate relation of stress and strain of UHMWPE yarn, when the UHMWPE yarn is subjected to external cut force. The dynamic response of yarn and the contact volume of yarn and blade in the cutting have been identified to interpret cut failure mechanism of yarn. The experimental results show that yarn structure, blade edge, and test parameters have great influence on cut resistant property of UHMWPE yarn, and which are consistent with the theoretical analysis. It provides a theoretical basis for quantifying the cutting resistance of fabrics.
