<p>Polyamide monofilaments of heavy denier and having both high straight and high loop tenacity, are prepared by the coupled steps of melt-spinning, quenching, drawing and winding.

Pressurized steam is employed in the first draw stage to facilitate the drawing and to deorient the surface polymer of the monofilament,</p> |
