Abstract: A process for obtaining a hydrofiltering mesh knitting material for curing comprises combining oleofinic, polyamide and polyester textile fibers in order to obtain a mesh knitting comprises subjecting the knitting to a thermic finishing by placing a formation of the knitting within an autoclave and injecting the autoclave by aspersion with a water steam having a pH from 5 to 6 and at a pressure of 1.5 kilograms per square centimeter at a temperature of 130.degree. C. for 30 minutes. The knitting which is obtained in this process comprises 30% oleofinic fibers, 34% of polyamide fibers and 36% of polyester fibers. The form knitting is advantageously given a further thermic finishing so that it is tightened by 2.1%.
