Cut-resistant functional coated aramid knitted textiles

The effect of SiO2 (0.5–2.5 wt%) with a particle size of 1–5 μm on the rheological and tensile properties as well as cut resistance of aramid fabrics coated with a thin layer of silica-containing latex was investigated. The rheological properties of the latex were assessed based on the dependence of viscosity on shear rate. The developed polymer coatings belong to the group of nonlinear, shear-thinning viscoelastic fluids, since their viscosity decreases with increasing shear rate. A 40% increase in cut resistance was obtained with increasing SiO2 content in the latex.
