Abstract: The present invention relates to methods for making polyamide filaments, such as nylon 6,6, having high tensile strength. The invention also relates to yarns and other articles formed from such filaments. The invention is particularly useful for providing a filament yarn with tenacity equal or superior to the prior art at high spinning process speeds while retaining the ability to draw the yarn. The invention further relates to providing a filament yarn extruded from a delustered or pigmented polyamide polymer.

Abstract translation: 本发明涉及制造具有高拉伸强度的聚酰胺长丝如尼龙6,6的方法。 本发明还涉及由这种细丝形成的纱线和其它制品。 本发明特别可用于在保持牵引纱线的能力的同时提供在高纺丝工艺速度下等同于或优于现有技术的强度的长丝纱线。 本发明还涉及提供从消光或着色的聚酰胺聚合物挤出的长丝。
