摘要
A method includes drawing a roving thread from a roving bobbin through a roving guide, an aft drafting roller, and a mid drafting roller to a front drafting roller, and drawing a spandex core from a spandex bobbin using a guide roller. The method also includes associating the roving thread and the spandex core by drawing the roving thread and the spandex core in an approximately parallel fashion through the front drafting roller, and drawing the associated roving thread and the spandex core through a lappet hook and an anti-ballooning guide. Further, the method includes winding the drawn associated roving thread and the spandex core on a ring-frame bobbin including a ring traveler attached to a rotatable ring. The circular motion of the ring traveler around the ring-frame bobbin causes the drawn associated roving thread to twist around the drawn associated spandex core, forming a core spun yarn.
