Abstract:
1. A fabric composed of polyolefin fiber, obtainable by a process comprising the following steps a) to c) of a) treating an untreated textile fabric consisting of polyolefin fiber to an extent in the range from 90% to 100% by weight in a plasma under such conditions that, after step a) has been carried out, the fabric has a surface tension in the range from 35 to 60 mN/m, b) treating the fabric obtained after step a) with a polyorganosiloxane containing R and units of the formula (II) where each R is independently CH each X is a radical of the formula (III) where t is from 1 to 4, z is from 5 to 60, in each unit of the formula one of R c) treating the fabric with a polymer containing perfluoroalkyl (RF) groups, this polymer being a polyacrylic polymer having RF groups or a polyurethane having RF groups or a mixture of such polymers, this step c) being carried out concurrently with step b) or later than step b).
