ABSTRACT:
A method for producing a hydrophobically finished aramid fabric includes at leasta) providing an aramid yarn,b) applying a water-repellent agent to the aramid yarn,c) drying the aramid yarn resulting from step b),d) producing a fabric from the aramid yarn resulting from step c), ande) heat treating the fabric. The fabric is used to produce an antiballistically effective article.The v50values for the hydrophobically finished fabrics of the invention are in the wet state higher than, and in the dry state at least as high as or higher than, the values for hydrophobically finished fabrics not of the invention in the wet and dry states, respectively.
