ABSTRACT:
Treated glass fibers are provided that are more dispersible in aqueous media. The glass fibers are treated with a composition having a nonionic surfactant and a cationic quaternary ammonium salt surfactant. The composition may be added simultaneously or sequentially with the chopped glass fibers to the aqueous media in which the glass fibers are to be dispersed. Also, glass fibers can be treated with an aqueous treating composition having the composition and produced into wet or dry chopped glass fibers having a length of about 1/16 of an inch to about 3 inches. The treated glass fibers have good dispersibility in aqueous media with or without the addition of dispersing agents.
