Alignment or substantial alignment of fibre is maintained by applying vacuum to the mould, by electrostatic means, or by coating the fibre with resin prior to application to the moulding tool and heating the moulding tool surface, or by coating or impregnating the fibre with a ferric powder and magnetizing the moulding tool, or by applying a mist layer of epoxy in front of the shortened lengths of fibres. Fibre lengths and deposition rates are varied as required. The method facilitates fully automated production reducing process time and component costs. The invention also comprises a corresponding moulded product.Type: ApplicationFiled: November 16, 2007Publication date: April 22, 2010Applicant: BENTLEY MOTORS LIMITEDInventor: Antony Dodworth

Patent number: 7560142Abstract: A fiber containing a bound active material, such as a metal oxide, under 20 microns in diameter. The inventive fiber is formed through the mixing of the fibers with a cationic or anionic polymer in one tank, the active material with a cationic or anionic polymer in a second tank, the opposite zeta potential of that used with the active material, and then mixing the active material/polymer and fiber/polymer blends together.Type: GrantFiled: September 8, 2006Date of Patent: July 14, 2009Assignee: Graver Technologies LLCInventors: Walter Bass, Angelo Pantaleo, John Schroeder, Samuel Vetrano

Publication number: 20090025359Abstract: Input fibers to be used for the manufacture of textile components are cut to a proper length [113]. The fibers are metallized [115] with silver and copper. The metallized fibers are opened [121] and blended [123] with other fibers. The blended fibers are preferably opened again [125]. Then the blended fibers are oriented [127] and drawn [129] into a sliver. Roving [140] may be applied to the sliver to condense the fibers. The length of the fibers, the denier of the fibers, the amount of metal coating and composition of the metal coating are selected to provide an optimum amount of metal ion discharge to have the proper antimicrobial properties, while optimizing wound healing properties, and minimizing manufacturing costs.Type: ApplicationFiled: May 8, 2006Publication date: January 29, 2009Inventors: N Satish Chandra, William F.

Patent number: 7410650Abstract: A method of fabricating nano-silver fibers is provided. An organic solution of a dispersant is prepared. Then, a silver salt and a reductant are added into the organic solution. The organic solution is stirred to let the silver salt and the reductant react to form silver nanoparticles dispersed in the organic solution uniformly. Next, a spinnable polymer resin is dissolved in the organic solution to form a spinning solution. A wet spinning method is performed to let the spinning solution form nano-silver fibers.Type: GrantFiled: January 19, 2006Date of Patent: August 12, 2008Assignee: Taiwan Textile Research InstituteInventor: Jia-Peng Lin
