Publication number: 20040131822Abstract: An ozone fade resistant dyed carpet made of dyed sheath/core face fibers has a sheath substantially or completely covering the core. The sheath is composed of a fiber-forming polymer which is inherently chemically compatible and is selected from polymers that are resistant to dye migration and yet inherently chemically compatible with the core polymer. The face fibers are dyed with at least one acid dye, basic dye or disperse dye and resist ozone fading as indicated by a CIEL*a*b* total color difference from the original unexposed sample after at least 3 cycles of ozone fading that is less than one-half of the CIEL*a*b* total color difference seen for a fiber composed substantially completely of said core polyamide component that is dyed with the same dyes. The fibers may be cabled and heatset in which case even more substantial improvement in the ozone fastness is observed.Type: ApplicationFiled: December 22, 2003Publication date: July 8, 2004Applicant: Honeywell International, Inc.Inventors: Matthew B. Hoyt, Bobby J. Bailey, Stanley A. McIntosh, Phillip E. Wilson, Gary W. Shore

Patent number: 6531218Abstract: Dyeable and dyed filaments have a core and a sheath which entirely surrounds the core. The core is formed of a core polymer which is susceptible to dyeing by a dye bath chemical, while the sheath is formed of a sheath polymer which is resistant to dyeing by the dye bath chemical. When the filament is brought into contact with a dye bath containing the dye chemical, the dye chemical in the dye bath will physically diffuse or migrate through the sheath polymer to cause the core polymer to be dyed a color of the dye bath chemical, while the sheath polymer is substantially undyed thereby.Type: GrantFiled: April 30, 2001Date of Patent: March 11, 2003Assignee: BASF CorporationInventors: Matthew B.

Publication number: 20010046583Abstract: An acid-dye and coffee stain resistant carpet has sheath/core bicomponent face fibers affixed in a backing material and bound thereto. The face fibers have a core of a first polyamide component and a sheath which substantially or completely covers the core of a second polyamide component which is inherently chemically compatible with the first polyamide component. In an uncolored state, the carpet has a red drink staining depth of less than 15 CIE &Dgr;E units and a coffee staining depth of less than about 10 CIE &Dgr;E units.Type: ApplicationFiled: May 17, 2001Publication date: November 29, 2001Inventors: Phillip E.

Patent number: 6017479Abstract: Multicomponent fibers and methods and apparatus for producing the same are provided such that an inter-domain boundary layer is interposed between distinct domains formed of incompatible polymers so as to minimize (if not eliminate entirely) separation of the domains at their interfacial boundary. The inter-domain boundary layer is formed of a heterogeneous mixture of the polymers forming the respective adjacent domains between which the boundary layer is interposed. The inter-boundary layer will most preferably include rivulets or fingers of each polymer forming the adjacent domains which interlock with one another in a randomly tortuous manner. These different polymer rivulets thereby effectively increase the surface area and mechanical interlocking at the interfacial boundary between the fiber domains thereby increasing the adhesion therebetween.Type: GrantFiled: November 20, 1998Date of Patent: January 25, 2000Assignee: BASF CorporationInventors: Charles F. Helms, Jr., Diane R. Kent, Matthew B. Hoyt, James R. Bristow, Phillip E. Wilson

Patent number: 5664455Abstract: A laboratory-scale device for assisting in the simulation of heat setting conditions includes a pair of laterally spaced-apart flexible heat-resistant cords (e.g., formed of aramid fibers) tensioned between forward and rearward rigid cross-support bars. At least one rigid tensioning bar is provided parallel to the support cords and extending between the cross-support bars so as to maintain the desired tension on the flexible heat-resistant cords. The tensioning bar thus allows for manual or automated lateral winding of the synthetic heat-settable fibers or yarns about the spaced-apart heat-resistant cords during preparation of the device for a laboratory test run. The tensioning bar may thereafter be removed once the device has been secured in position with the laboratory heat-setting oven. In such a manner, therefore, various effects on heat-setting conditions simulating can be investigated.Type: GrantFiled: June 7, 1995Date of Patent: September 9, 1997Assignee: BASF CorporationInventors: Ann S. Johnson, John A. Kilpatrick, Lewis W. Davis, Jr., David B. Ledford, Larry D. Henderson, Phillip E. Wilson

Patent number: 5393219Abstract: A spin pack for spinning multiple components includes a distribution device which distributes mutually separated molten polymer streams to a spinneret so that each mutually separated molten polymer stream is accessible at each active spinneret backhole. Intermediate the spinneret and the distribution device, a selection assembly selects which, if any, mutually separated molten polymer stream flows into which backhole.Type: GrantFiled: April 30, 1993Date of Patent: February 28, 1995Assignee: BASF CorporationInventors: Gerry A.

Patent number: 5369483Abstract: The concentration of a colorant in a stream of molten polymer is measured by inserting a probe adjacent to the stream. The probe has integral therein collection means and illumination means. The steam is illuminated with the illumination means to cause electromagnetic radiation to be reflected from the molten polymer. The electromagnetic reflectance is collected, transmitted to a measurement device remote from the molten stream and quantified as a function of the concentration of the colorant.Type: GrantFiled: May 7, 1993Date of Patent: November 29, 1994Assignee: BASF CorporationInventor: Phillip E.
