Low crystallinity polyester yarn produced at ultra high spinning speeds. |
摘要 |
<p>Spinning of polyethylene terephthalate yarn at speeds in excess of 5000 meters per minute using a gas management technique of the gas surrounding the threadline to control the temperature and attenuation profiles of a spinning threadline provides a means to produce a low crystallinity polyester yarn with a relatively high elongation to break.</p> |
