Patent number: 6203743Abstract: An apparatus and method for heat setting a traveling tow of synthetic filaments utilizing a high pressure dewatering nip roll mechanism to remove moisture from the tow prior to heat setting. The high pressure dewatering nip roll mechanism includes a pair of nip rollers exerting a pressure of between about 500 and 2000 pounds per linear inch of transverse nip contact on the traveling tow prior to the tow entering a heat setting apparatus such as a calender apparatus. Moisture content of the traveling tow is reduced to less than 10% moisture by weight and preferably less than 5%. Reducing the moisture content of the tow prior to heat setting reduces the energy required to heat set the tow and, contrary to the prevailing wisdom in the art, does not damage the unheat set filaments of the tow.Type: GrantFiled: October 1, 1999Date of Patent: March 20, 2001Inventor: Glen Patrick Reese

Patent number: 6168747Abstract: A calendering apparatus and method for heatsetting a traveling multi-filament tow basically utilizes plural heated rolls about which the tow travels in a sinuous path to be conductively heated by the rolls and, at each roll, a plurality of infrared lamps in an arcuate arrangement facing the portion of the respective roll in contact with the tow simultaneously applies infrared radiation to the opposite side of the tow. In one embodiment, this arrangement of infrared lamps is retrofitted to a conventional calendering apparatus. An alternative embodiment provides for reducing or eliminating the number of calender rolls followed by a series of infrared heating tunnels collectively effective to accomplish heatsetting of the tow. The speed and/or throughput rate of each calendering apparatus and method is effectively twice that of conventional equipment of similar size.Type: GrantFiled: June 21, 1999Date of Patent: January 2, 2001Assignee: Arteva North America S.A.R.L.Inventors: Glen P. Reese, Marshall Ledbetter, Charles David Carlson, Jr., Johannes C. Kuppe

Patent number: 6138336Abstract: A process to produce a plyed holographic yarn in which the slit film is allowed to be pulled from its source rather than being driven by drive rolls. The slit film and at least one other yarn are plyed and textured in an air texturing jet.Type: GrantFiled: November 23, 1999Date of Patent: October 31, 2000Assignee: Milliken & CompanyInventor: Andre M. Goineau

Patent number: 6134757Abstract: A processing method for splitting thread spool is to: lay a spool of resin thread on a feeding wheel equipped with a broken end lifter; deliver the resin thread through an auxiliary piece and a first yarn cutter; split the resin thread into equalized finer threads in virtue of a plurality of resin wheels and rotators; deliver the split finer thread to undergo rolling of a pressing and positioning roller; and pull the finer thread to reach a winding spool for being wound to form a yarn spool pending knitting into silk socks.Type: GrantFiled: November 18, 1999Date of Patent: October 24, 2000Inventor: Ho-Pin Wei

Patent number: 6107218Abstract: The present invention is directed to a new chenille yarn and a method of making the same. The chenille yarn may be used on conventional weaving equipment, including air jet and water jet weaving machines, to produce simulated pile fabrics having superior abrasion resistance and improved hand. The present invention is also directed to a method of making fabrics containing the chenille yarn, and various uses for the fabrics, especially as residential upholstery fabrics, decorative throws, contract fabrics, automotive fabrics, and bedding fabrics for use in the home.Type: GrantFiled: May 11, 1998Date of Patent: August 22, 2000Assignee: Chatham IncorporatedInventor: J.
