Patent number: 6416859Abstract: Polymeric compositions include a nonaqueous additive system having dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier which may be added directly to a melt flow of a polymeric host material. The additive system employed in the polymeric systems is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of host polymeric material, shaped objects of the polymeric material (e.g., melt-spun filaments) having different additive attributes may be produced on a continuous basis without shutting down the shaping operation.Type: GrantFiled: October 17, 2000Date of Patent: July 9, 2002Assignee: BASF CorporationInventors: Donald Caswell, Frank R. Jones, David B. Ledford, Stanley A. McIntosh, Gary W. Shore, Karl H. Buchanan, Wayne S. Stanko, G. Daniel Gasperson, Charles F. Helms, Jr.

Patent number: 6245694Abstract: Automotive bedliners (e.g., for pickup trucks) are formed from a sheet of thermoplastic material having electrically conductive fibers embedded in a surface thereof in an amount sufficient to render said sheet electrically conductive. The bedliners are most preferably formed of a thermoplastic material (e.g., a polyolefin, such a polyethylene and/or polypropylene) having a matrix of electrically conductive fibers physically embedded in at least one side thereof. By physically embedding the conductive fibers in a surface of the bedliner, the fibers are capable of establishing electrical continuity between the bedliner and the pickup truck bed thereby effectively dissipating static electrical charges.Type: GrantFiled: October 1, 1997Date of Patent: June 12, 2001Assignee: Shakespeare Conductive Fibers, LLCInventors: Grover L. Davenport, Wayne S. Stanko, Allen Ray, Everett C. Cox, Michael A. Davis, Gary M. Carnes

Patent number: 5834089Abstract: Synthetic filaments include a nonaqueous additive system having dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier. The additive system is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of polymeric material, melt-spun filaments having different additive attributes may be produced on a continuous basis (i.e., without shutting down the spinning operation). The filaments may be included in yarns which are formed into carpet structures.Type: GrantFiled: March 3, 1997Date of Patent: November 10, 1998Assignee: BASF CorporationInventors: Frank R. Jones, Stanley A. McIntosh, Gary A. Shore, Karl H. Buchanan, David B. Ledford, Wayne S. Stanko, G. Daniel Gasperson, Charles F. Helms, Jr.

Patent number: 5833893Abstract: Methods of continuously producing sequential lengths of different additive-containing melt-spun filaments include continuously supplying a melt-spinnable polymeric host material to orifices of a spinneret and controllably dosing at least one dispersible additive concentrate system containing a pigment in a liquid nonaqueous polymeric carrier to the melt flow of polymeric host material upstream of the spinneret orifices. In such a manner, a first polymeric mixture of the dispersible additive concentrate system and the polymeric host material is obtained which achieves an additive attribute. During a first time interval, the first mixture is extruded through the spinneret orifices; and thereafter, during a second subsequent time interval, the dosing of the at least one dispersible additive is changed so as to form a second mixture having a second additive attribute different from the first additive attribute while continuously supplying the melt flow of polymeric host material to the spinneret orifices.Type: GrantFiled: March 3, 1997Date of Patent: November 10, 1998Assignee: BASF CorporationInventors: Frank R. Jones, Stanley A. McIntosh, Gary W. Shore, Karl H. Buchanan, David B. Ledford, Wayne S. Stanko, G. Daniel Gasperson, Charles F. Helms, Jr.

Patent number: 5800746Abstract: Nonaqueous additive systems which includes dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier are added directly to a melt flow of a polymeric host material prior to spinning. The additive system is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of polymeric material, melt-spun filaments having different additive attributes may be produced on a continuous basis (i.e., without shutting down the spinning operation).Type: GrantFiled: March 3, 1997Date of Patent: September 1, 1998Assignee: BASF CorporationInventors: Frank R.

Patent number: 5070185Abstract: High shrinkage polyester fibers having good strength and uniform dyeability are disclosed, along with a method of producing the high shrinkage polyester fibers, by drawing a feeder yarn having a birefringence (n) of at least 0.0175 at a temperature below the glass transition temperature for the polyester and with carefully controlled draw ratios.Type: GrantFiled: March 30, 1990Date of Patent: December 3, 1991Assignee: BASF CorporationInventor: Wayne S. Stanko

Patent number: 4970038Abstract: A yarn comprising polyester fibers having an improved balance of properties (tenacity and boiling water shrinkage) is produced within predetermined limits. The polyester yarn is prepared by cold drawing a partially oriented feeder yarn, partially annealing the drawn yarn, and subsequently annealing the partially annealed cold drawn yarn at controlled tensions.Type: GrantFiled: November 29, 1988Date of Patent: November 13, 1990Assignee: BASF CorporationInventor: Wayne S. Stanko

Patent number: 4906519Abstract: This invention pertains to variable denier filaments prepared from synthetic polymers having a glass transition temperature of at least 30.degree. C. and yarns made therefrom. The filaments have longer length slubs, which results in their use in fabrics desiring a variable texture and dyeing effects. The filaments are prepared by drawing at ambient temperature a feeder yarn having sufficient molecular orientation at carefully controlled draw ratios and in draw zones having a specified length.Type: GrantFiled: June 6, 1988Date of Patent: March 6, 1990Assignee: BASF CorporationInventors: Wayne S. Stanko, Stuart H. Rice
