High-strength spun yarn produced from continuous high-modulus filaments, and process for making same
Patent number: 7188462Abstract: A process for making a high-strength spun yarn begins by feeding one or more tows of substantially uncrimped continuous filaments of high-modulus material having a tensile modulus exceeding about 20×106 psi through a high-speed stretch-breaking apparatus operating at low total draft ratio (preferably about 2.0) to break the filaments into high-modulus staple fibers having an average length in the range of about 5 to 6 inches. The tows advantageously are heavy, for example, having a denier of about 25,000 to about 500,000. Following the stretch-breaking step, the staple fibers are collected in sliver cans, and the staple fibers are advanced from the sliver cans to a spinning machine, where the fibers are spun into yarn. An important aspect of the invention is that no intermediate processes are performed between the stretch-breaking and spinning processes, which minimizes disruption of the alignment of and damage to the staple fibers.Type: GrantFiled: August 6, 2004Date of Patent: March 13, 2007Assignee: Stowe-Pharr Mills, Inc.Inventors: James Easton Hendrix, Donald Hershel Hamrick, Harold B.

According to such denier-mixed composite yarn, superior dry feel fullness and softness can be imparted to woven and knit fabrics.Type: GrantFiled: December 22, 1986Date of Patent: December 15, 1987Assignee: Nippon Ester Co., Ltd.Inventors: Keizo Tsujimoto, Takashi Katagiri, Eiji Ichihashi, Hitoshi Otsubo

Patent number: 4698956Abstract: A continuous process of making a blended yarn of staple fiber and long-fiber or filamentary material in which the long-fiber or filamentary material is passed through a rupture zone to produce lengths thereof which are fed directly into an air stream with the staple fibers to produce an intimate blend which is conveyed by the air stream directly to an open end spinning device which produces the yarn.Type: GrantFiled: May 29, 1986Date of Patent: October 13, 1987Assignee: Gentex CorporationInventors: Steven R. Clarke, John B. Price, Robert A. Sallavanti, Stephen P. Zawislak

Patent number: 4519201Abstract: The present invention relates to an improved process for blending together textile like fibers exhibiting a relatively high modulus of elasticity together with textile fibers exhibiting a relatively low modulus of elasticity which blend can further be converted into a high quality blended yarn structure. When the textile fibers exhibiting the relatively high modulus of elasticity are also electrically conductive, such as e.g. metal or carbon fibers, then the resulting yarns and fabrics can be designed with a predetermined level of electrical conductivity.Type: GrantFiled: September 8, 1982Date of Patent: May 28, 1985Inventor: John J.
