Abstract
The present invention relates to surface-modified polyolefin fibers, the use of these fibers in hydraulic binder compositions, hydraulic binder compositions containing these fibers and a method for reinforcing hydraulic binder compositions.
Claims15
Surface-modified polyolefin fibers obtained by a process comprising the steps of
- a) a pretreatment of the polyolefin fibers by plasma treatment with an electrically excitable gas in a plasma reactor to obtain polyolefin fibers with polar groups on the surface and
- b) plasma treatment of the polyolefin fibers with an electrically excitable gas in the presence of a gaseous siloxane or silazane compound in a plasma reactor.
