Effect of structural parameters on the cut resistance of para-aramid and ultra-high molecular weight polyethylene weft knitted fabrics

Abstract

In this study, the cut resistance of pure and hybrid knitted para-aramid and ultra-high molecular weight polyethylene fabrics with different structural parameters were measured according to ASTM F1790. The results showed that there is an optimum value for stitch density in which the cut resistance is maximized. The highest and the lowest cut resistance was observed in the courses and the wales directions, respectively. The interposed values were obtained in the bias direction. Coating with casting polyurethane resin increased the cut resistance of the fabrics. Para-aramid samples had higher cut resistance than UHMWPE samples in higher stitch densities, and hybrid samples showed a higher cut resistance than the pure ones, due to some of their structural features.
