Abstract: Fibrillated polyester textile materials and methods for producing same are disclosed. Such fibrillated polyester textile materials have a body portion formed of a plurality of polyester filaments in which the filaments contain a plurality of fibrils on the convex side portion of the filament curvature pointing away from the body portion of the textile material. The methods disclosed include treating the polyester textile material with a swelling agent and abrading the resulting material to produce the desired fibrillated polyester textile material. Also disclosed is a unique method wherein the molecular weight of the polyester employed to make up the textile material is lowered prior to the polyester textile material being treated with the swelling agent and abraded.
