Process for improving crystallinity in nylon 6 |
摘要 |
In continuous spin-draw-winding of nylon 6 to produce yarn filaments of mixed beta-alpha crystalline morphology, the improvement wherein prior to drawing, a spin finish emulsion containing from about 0.1 to about 6% by weight of benzyl alcohol is applied to the filaments to enhance conversion of the beta uniformity of dye acceptance to the drawn filaments.
