Abstract

988,068. Brush filaments. E. B. & A. C. WHITING CO. Sept. 12, 1962, No. 34881/62. Drawings to Specification. Heading A4K. [Also in Division B5] A brush bristle of oriented isotactic polypropylene is prepared from filaments made by melt-spinning polypropylene, causing the filaments to travel only a short distance through air, drawing them through a bath of a non-solvent liquid at a temperature not exceeding 12.8‹C. and then stretching them at a temperature of 126.7‹C. to 151.7‹C. (see Division B5). The brush bristles may be prepared by collecting a group of the filaments in a bunch and applying a shearing force to the bundle in a plane transverse to the longitudinal axis of the bundle to cut the filaments to a desired length. When prepared in this manner the brush bristles each have an integral barb at one end extending laterally from the bristle. The barb may be triangular in shape and terminate in a point.
