ABSTRACT:
Modifying a polyester with tetraethyl silicate or like oxysilicon chain-brancher to provide a draw-texturing feed yarn that can be draw-textured at a speed of at least 500 mpm without excessive filament breaks, and with other advantages in the resulting textured yarns, such as improved bulk and dyeability over unmodified polyester yarns textured under similar conditions, and preferably without sacrificing dye uniformity.
