Patent number: 7585442Abstract: A process for making a cigarette tow comprising: spinning a dope; taking-up the as-spun cellulose acetate filaments; lubricating the filaments; forming a tow from the filaments; crimping the tow with a stuffer box crimper; drying the crimped tow; and baling the dried crimped tow. The process further comprises at least two of the following: A. crimping further comprising one roller of the pair of nip rollers being adapted to induce crimp into the tow; B. crimping further comprising one roller of the pair of nip rollers being made of a solid ceramic material; C. crimping further comprising a pair of tow edge lubricators; D. crimping further comprising a steam injector; E. further comprising plasticizing the tow; F. lubricating the filaments further comprises a finish consisting of a water emulsion.Type: GrantFiled: June 25, 2004Date of Patent: September 8, 2009Assignee: Celanese Acetate, LLCInventors: Philip I. L. Caenen, Gary B. Ellison, David O. Kutscher, William S. Sanderson, Mark E. Scarborough, Donald T. Stilwell

Publication number: 20090117269Abstract: An electrically conductive composite material includes metallic nanostrands distributed throughout a matrix constructed of a polymer, ceramic, or elastomer. The nanostrands may have an average diameter under four microns and an average aspect ratio over ten-to-one. Larger fibers may also be included to enhance electrical conductivity or other properties. The nanostrands and/or fibers may be magnetically oriented to enhance electrical conductivity along one direction. A pressure sensor may be formed by utilizing an elastomer for the matrix. Electrical conductivity through the composite material varies in proportion to deflection of the elastomer. A composite material may be applied to a surface as an electrically conductive paint. Composite materials may be made by cutting a blank of the nanostrands to the desired shape, inserting the matrix, and curing the matrix. Alternatively, a suspension agent may first be used to dispose powdered nanostrands in the desired shape.Type: ApplicationFiled: December 11, 2006Publication date: May 7, 2009Applicant: Metal Matrix Composites CompanyInventors: George Clayton Hansen, Lauren Hansen, William C.

Patent number: 7476352Abstract: Methods and systems for extruding polymeric fibers are disclosed. The extrusion process preferably involves the delivery of a lubricant separately from a polymer melt stream to each orifice of an extrusion die such that the lubricant preferably encases the polymer melt stream as it passes through the die orifice.Type: GrantFiled: May 21, 2004Date of Patent: January 13, 2009Assignee: 3M Innovative Properties CompanyInventors: Bruce B. Wilson, Roger J. Stumo, Stanley C. Erickson, William L. Kopecky, James C. Breister

Patent number: 7445737Abstract: In the manufacture of a fiber tow, particularly cellulose acetate tow, a stuffer box crimper has one roller adapted to induce crimp into the tow. This roller induces crimp by preferentially weakening a portion of the tow. This roller has an axially grooved surface. This roller may be located in the stuffer box crimper or before the stuffer box crimper.Type: GrantFiled: June 25, 2004Date of Patent: November 4, 2008Assignee: Celanese Acetate, LLCInventors: William S. Sanderson, Mark E. Scarborough
