2 the woven is then cleaned for example by washing it in the loom state by means of a jigger or continuous washing process to remove in particular residual spin finish and the like the woven thus washed and dried is then impregnated with an aqueous impregnant this impregnant comprises one or more fungicides and also one or more hydrophobicizers the woven is then impregnated so thoroughly that the fibers and yarns are fully enveloped by impregnant this is necessary to obtain uniform coating in the subsequent coating process after the impregnating step the woven thus impregnated is dried the fungicide is generally present in the impregnant in an amount of 20 40 g preferably 30 g per liter of water the impregnant further comprises a hydrophobicizer in an amount of for example 4 10 g especially 7 g per liter of water after the impregnating step the woven thus impregnated and dried is coated aqueous dispersions of hydrophilic polyurethanes are used for coating the aqueous dispersion shall comprise sufficient polyurethane to ensure that an adequate amount of polyurethane is applied to the woven the amount is advantageously determined such that the fabric comprises between 30 and 50 g of coating add on per.
