Evaluation of laser texturing in fabricating cut-resistant surfaces for protective gloves

Abstract

The aim of the study was to evaluate the effects of laser texturing of coated textile materials on their cut resistance. The investigated material was an aramid knitted fabric coated with a polymer layer made of an acrylic-styrene dispersion functionalized with particles of silicon carbide (SiC). The distribution of SiC particles in the coating microstructure was assessed on the basis of microscopic observations (scanning electron microscopy). The coating was laser textured, and then the cut resistance of the assembly was determined using a rectangular blade. The findings showed that laser texturing improved the cut resistance of the tested materials, causing a fourfold increase in that parameter as compared to non-modified textile materials. This fact may improve the safety of workers wearing protective gloves in terms of cut protection.
