Abstract
A composition and process in which a silane coupling agent has nano-mineral particles grafted to the silane copolymer molecules in the coupling agent and such coupling agent is applied to a scoured fabric prior to the fabric being coated with a polymeric coating.
Claims7
A composition for use in finishing mineral and carbon fibers and fabrics comprising:
- a). a coupling agent;
- and
- b). nano-mineral particles dispersed within said coupling agent and grafted to molecules of the coupling agent to form a finish composition whereby upon application of the composition to a mineral or carbon fiber surface the nano-mineral particles graft onto the fiber or fabric surface and form a three-dimensional matrix of the coupling agent.
A process for finishing mineral and carbon fibers and fabrics comprising the steps of:
- a) scouring the fabric to remove any processing aids and impurities on the surface thereof;
- b) applying a composition of a silane coupling agent having nano-mineral particles grafted to silane copolymer molecules therein to the scoured fabric to treat same;
- and
- c) applying a polymeric coating to said treated fabric.
