Development of Textile Laminates for Improved Cut Resistance

Abstract

Fiber structures, yarn structures, and mechanical properties of fibers namely tensile modulus, tenacity, and elongation, are the key performance indicators of fabric cut resistance. p-aramid and UHDPE (Ultra High Density Polyethylene) based high performance fibers are most commonly used for protection against mechanical risks. Specially engineered composite yarns and fabrics enhance cut resistance. This paper discusses the influence of textile structure configuration on the performance of cut resistant textiles. A three tier laminate composite was made using knitted Kevlar fabric, (p-aramid) as the outer surface, polyurethane foam in the middle and a knitted nylon fabric as the skin contact layer. This specially engineered laminate showed a 20% increase in cut resistance when compared with the Kevlar fabric used for lamination. The combination of breathable PU foam and knitted fabric yielded high stretch with improved breathability and dexterity.
