ABSTRACT:
Modifying a polyester with special chain-brancher residues in carefully controlled amounts to provide a draw-texturing feed yarn that can be draw-textured at a speed of 1,000 mpm without excessive filament breaks, and with other advantages in the resulting textured yarns, such as improved bulk and dyeability over prior polyester yarns that could not be satisfactorily textured under similar conditions.
