ABSTRACT:
A continuous process for spinning and drawing polyamide filaments with the steps of melting a polyamide and spinning the filaments from the molten polyamide through a spinnerette, quenching the filaments, applying a yarn finish to the filaments, applying steam and heat to the filaments by a steam and heating unit which consists of a steam box and at least one heated godet, drawing the filaments, and optionally texturing the filaments. The resulting filaments have low shrinkage, high crystallinity, and a high percentage of alpha crystals.
