Patent number: 8910896Abstract: A method of winding an elastomeric yarn, such as spandex, onto a spool includes the steps of providing a spool; providing an elastomeric yarn; rotating the spool at a speed to define a spool rotation speed; moving the yarn traversely with respect to the spool in an alternating to and fro manner to define a traverse frequency; winding the yarn onto the spool; controlling the ratio of the spool rotation speed to the traverse frequency to define a wind ratio during the winding of the yarn onto the spool; and decreasing the traverse speed as the yarn is wound onto the spool in an inverse proportion to an amount of yarn that has been wound. The winding of the yarn onto the spool forms a yarn cake on the spool. The traverse speed may be decreased in inverse proportion to a diameter of the yarn cake. The method may further include the step of shifting the yarn by a pitch for each rotation of the spool.Type: GrantFiled: October 23, 2009Date of Patent: December 16, 2014Assignee: INVISTA North America S. à r. l.Inventor: Joseph E.

Patent number: 8850786Abstract: Intermittently colored yarns having an intermittent and random dye spacing pattern, and systems and methods of making the same, are disclosed. Such intermittently colored yarns exhibit higher quality and lower manufacturing costs over the known intermittently colored yarns. The intermittent coloring takes place while the yarn is in caterpillar form. Carpets made from such intermittently colored yarns exhibit enhanced aesthetics over carpets made from known intermittently colored yarns. Alternatively, a stain resist, colorless base dye, or bleaching agent can be applied in the same intermittent and random spacing pattern to the intermittently colored yarns prior to subsequent dyeing. This creates a mirror image like color effect to the resulting yarn.Type: GrantFiled: June 4, 2010Date of Patent: October 7, 2014Assignee: INVISTA North America S.à.r.l.Inventors: Wae-Hai Tung, Subhash Chand, John Paul Ryan
