Abstract
Abstract An aqueous size composition for glass fibers is disclosed which includes a coupling agent, a binder or film former material and a thermoplastic polymer resin powder, wherein said composition is applied to the glass fiber surfaces during the fiber forming process. A rheology modifier material may be added to the size composition. One embodiment of the composition includes an organosilane coupling agent, a polyethylene oxide binder material and a polyamide thermoplastic polymer resin.
