Oleophobic polyolefin fiber materials

摘要

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.
