Patent number: 5996328Abstract: Individual differently colored or colorable feed filament ends are withdrawn from respective creel-mounted packages and passed through a separation guide. The separation guide serves to "normalize" the filament end-to-end positions and tensions. That is, the separation guide will cause the individual feed ends to be in specific predetermined positions relative to the other feed ends regardless of the position of the package on the creel. In addition, the separation guide will effectively cause a short length of each feed end to be parallel to, and separated by a substantially uniform distance from, corresponding lengths of the other feed ends. This parallel alignment of individual end lengths and the substantially uniform filament end-to-end positioning thereby imparts substantially uniform tensions on the feed ends while substantially maintaining their respective positions in the combined yarn product relative to one another.Type: GrantFiled: October 22, 1997Date of Patent: December 7, 1999Assignee: BASF CoporationInventors: Willis M. King, Melvin R. Thompson, Andrew M. Coons, III, Myles W. Sterling, Leroy Boseman, Donald E. Wright

Patent number: 5715584Abstract: Multiple (at least two) differently colored or colorable feed yarns are fed from their respective yarn packages to a multi-position interlacer manifold assembly. The feed yarns are maintained separate and apart from one another and are passed in this separated state through individual interlacer jets associated with the interlacer manifold assembly. The individual yarns are thereafter conveyed to a conventional yarn processing system (e.g., an apparatus known colloquially in the art as a "Gilbos" apparatus) where they are entangled with one another to provide a finished yarn in which the individual yarn components remain substantially coherent throughout the finished yarn. The individual interlaced yarns thus become entangled with one another when subjected to the yarn processing system without substantial inter-yarn blending or commingling occurring (which blending or commingling would thereby cause the constituent yarns to become nearly indistinguishable from one another).Type: GrantFiled: March 25, 1996Date of Patent: February 10, 1998Assignee: BASF CorporationInventors: Andrew M. Coons, III, Willis M. King, Melvin R. Thompson, Leonard C. Vickery, Jr., Ian Wolstenholme

Patent number: 5613285Abstract: The process includes the sequential steps of supplying in a separated side-by-side parallel relationship to a yarn drawing apparatus first multifilament feed yarn and second multifilament feed yarn which are differently colored or colorable with respect to each other; drawing the first feed yarn and the second feed yarn in the yarn drawing apparatus while keeping the first feed yarn and the second feed yarn in a relatively parallel relationship and separate from each other; making a bundle from the first drawn feed yarn and the second drawn feed yarn by simultaneously imparting false twist to the drawn first feed yarn and the drawn second feed yarn without commingling the first and second drawn feed yarns; and texturing the bundle without commingling to make a nontwisted, noncommingled singles yarn displaying two distinct unblended colors.Type: GrantFiled: November 1, 1994Date of Patent: March 25, 1997Assignee: BASF CorporationInventors: Roy E. Chester, Andrew M. Coons, III, Hugh G. Harrelson, Jr., Willis M. King, George E. Potter, Carl D. Sanford, Patrick C. Smith, Melvin R. Thompson, Leonard C. Vickery, Jr., Jerry M. Whitfield

Patent number: 5148586Abstract: A process for making a heather-dyeable or precolored heather yarn product comprises supplying a first crimped continuous filament yarn in the form of a loose matrix substantially free of filament entanglement and a second crimped continuous filament yarn which is differentially dyeable or precolored with respect to the first yarn. The second yarn is fed through a first entangling or interlacing zone and exposure of the second yarn to a fluid jet in the first entangling zone is randomly controlled to produce a color-point yarn product as the second yarn exits the first entangling zone, in which the color-point yarn product has relatively compact nodal regions of high entanglement of the filaments of the second yarn separated by bulkier regions of the same filaments relatively free of entanglement.Type: GrantFiled: February 5, 1991Date of Patent: September 22, 1992Assignee: BASF CorporationInventor: Andrew M.
