METHOD AND APPARATUS FOR PRODUCING POLYAMIDE FILAMENTS OF HIGH TENSILE STRENGTH BY HIGH SPEED SPINNING |
摘要 |
<p>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.</p> |
