Polyolefin fiber fabrics can be endowed with oil-repellent properties by treating them first in a plasma atmosphere to raise their surface tension, then with a polyorganosiloxane containing polyoxyalkylene groups and finally with a polyacrylate or polyurethane containing perfluoroalkyl radicals. The fabrics thus obtained are useful for medical as well as other applications.

Creases with excellent resistance to washing processes can be produced in 30 to 100% by weight wool fabrics by means of a specific process. The fabrics are preferably in the form of garments; the process can be used to produce trouser creases, for example. The process consists in applying at least one compound having isocyanate groups to the fabric and pressing creases into the fabric under certain moisture and temperature conditions.
