Publication number: 20160208419Abstract: Methods are provided to make composite yarns having a filamentary core with at least one elastic performance filament and at least one inelastic control filament. A fibrous sheath, preferably formed from spun staple fibers, surrounds the filamentary core, preferably substantially along the entire length thereof. The at least one elastic performance filament most preferably includes a spandex and/or a lastol filament. The at least one inelastic control filament is most preferably formed of a textured polymer or copolymer of a polyamide, a polyester, a polyolefin and mixtures thereof. Preferably, the fibrous sheath is formed of synthetic and/or natural staple fibers, most preferably staple cotton fibers. The elastic composite fibers find particular utility as a component part of a woven textile fabric, especially as a stretch denim fabric, which exhibits advantageous elastic recovery of at least about 95.0% (ASTM D3107).Type: ApplicationFiled: March 24, 2016Publication date: July 21, 2016Inventors: Ralph B. THARPE, JR., John L. ALLEN, JR., Fulton A. LITTLE, Reuben E. HART

Patent number: 4724429Abstract: A system for monitoring each of multiplicity of variables in the operation of a filter rod making machine includes sensors located at various points on the machine. These sensors measure the value of such variable parameters as the width of the tow, the alignment of the wrapping paper, the speed of the rollers and the level of plasticizer. Each measured value is compared against preset limit values in a microprocessor. If a variable is detected to be outside a range of acceptable values, an indication of this fact is displayed on a monitor. In response to this indication, an operator can decide whether to override the limit value or take corrective action. If corrective action is to be taken, the microprocessor causes a diagnostic chart to be displayed. This chart provides the operator with a sequence of troubleshooting steps that can be taken to isolate the source of a possible problem and perhaps correct it before there is a need to arrest the operation of the machine.Type: GrantFiled: March 7, 1986Date of Patent: February 9, 1988Assignee: Celanese CorporationInventors: William L. Millen, John L. Allen, Jr.

Patent number: 4660147Abstract: A method of controlling the flow of finish to a moving synthetic fibrous tow involves continuous non-contact monitoring of electrostatic voltage (ESV), tow speed and temperature by appropriate sensors which are interfaced with a computer that provides continuous computation of percent finish on the tow. Out of limit signals are relayed to the point of finish application to adjust the amount of finish being applied to the tow.Type: GrantFiled: August 23, 1985Date of Patent: April 21, 1987Assignee: E. I. du Pont de Nemours and CompanyInventors: John L. Allen, Jr., Teddy H. Grandstaff
