Abstract
Abstract A method for treating a solid material to give it hydrophilic and/or antistatic properties comprises applying a composition containing a silicone compound to the material which has one or more alkoxysilylalkyl groups and one or more polyoxyalkylene groups. In a preferred embodiment the method is used to treat fibers and fiber-containing materials. The composition can further contain a curing agent for the silicone. Emulsion compositions are particularly useful.
