Production of high cotton number or low denier core spun yarn for weaving of reactive fabric and enhanced bedding
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.
1. A method of producing a core spun yarn, comprising:
drawing a roving thread from a roving bobbin through a roving guide, immediately followed by an aft drafting roller, and immediately followed by a mid drafting roller to a front drafting roller;
drawing a spandex core from a spandex bobbin using a guide roller;
associating the roving thread drawn to the front drafting roller and the spandex core drawn using the guide roller by drawing the roving thread drawn to the front drafting roller and the spandex core drawn using the guide roller in an approximately parallel fashion through the front drafting roller;
drawing the associated roving thread and the spandex core through a lappet hook immediately followed by an anti-ballooning guide, the anti-ballooning guide configured to maintain ballooning of the associated roving thread and the spandex core within a certain limit;
executing, through a ring traveler attached to a rotatable ring, a circular motion around a ring-frame bobbin comprising the ring traveler attached to the rotatable ring to cause the drawn associated roving thread to twist around the drawn associated spandex core, forming the core spun yarn; and
wrapping, through the ring traveler, the formed core spun yarn on the ring-frame bobbin at a same time of rotation of a spindle of the ring-frame bobbin to form a roving-spandex bobbin.
2. The method of claim 1 , wherein the spandex core has a denier from 20 to 300.
3. The method of claim 1 , wherein the roving thread comprises at least one of cotton staple fibers and polyester staple fibers.
