ABSTRACT:
A method for melt spinning thermoplastic filament yarn is disclosed, wherein a plurality of filaments are withdrawn from a spinneret, and combined to form an advancing yarn. The advancing yarn is traversed onto a rotating bobbin to form a wound package, and the traversing speed is periodically rapidly changed so as to avoid the formation of undesirable patterns or ribbons. In addition, the advancing yarn is heated so as to lower its modulus of elasticity, so that the yarn tension and yarn denier remain within an acceptable range of variation during each change of the traversing speed.
