Patent number: 7361241Abstract: In order to produce a nonwoven fabric having elastomeric properties spun filaments (1), consisting preferably (but not essentially) of cellulose material such as cellulose acetate or solvent spun rayon, not in yarn formats, are corrugated or crimped in an overfeed process, as in stuffer box (6), into stabilized three dimensional batts. A proportion of filaments (3) of a thermal memory material, such as modified polyester, in a stretched format are included. The resulting batt is then subjected to controlled hydroentangling and a controlled heat treatment to yield three dimensional nonwoven fabrics with elastomeric properties due to contraction of the stretched filaments. Elastomeric memory material activated to shrink by ultrasonic treatment may be used in place of thermal memory material. The elastomeric properties can be adjusted to suit end-use requirements and applications are envisaged in the medical and hygiene areas.Type: GrantFiled: February 5, 2004Date of Patent: April 22, 2008Assignees: Fleissner GmbHInventors: Georg Martin Barth, Edmund Hugh Carus

Publication number: 20040224589Abstract: A method is disclosed for using discarded carpet segments or other recycled textiles to make wood-like material in sheets that are comparable to plywood. The carpet segments or other recycled materials are shredded, then layered across a slow-moving conveyor to form a thick, low-density belt of fibers. This belt is compressed between rollers, and then needle-punched, using needles with surface barbs that pull fibers downward and upward. This needle-punching causes fibers inside the mat to be pulled into vertical alignment (i.e., perpendicular to the top and bottom surfaces of a horizontal mat), to form a needle-punched mat that will hold together without chemical adhesives. A binder material is then applied to at least one and possibly both surfaces of the mat, by means such as spreading or spraying a liquid binder on either or both surfaces of the mat, or stretching a continuous film of the binder material across either or both surfaces of the mat.Type: ApplicationFiled: October 31, 2002Publication date: November 11, 2004Inventors: Forrest C. Bacon, Wendell R. Holland, Jesse D. Bacon

Patent number: 6814828Abstract: A method and device for producing melt-spun continuous threads includes two preparers spaced apart from one another, at each of which a partial quantity of a preparation is applied to the threads. A first preparation is performed upstream of a first draw-off device and a second downstream of the first draw-off device. As a result, high cohesion of the filaments in the thread is achieved.Type: GrantFiled: November 27, 2001Date of Patent: November 9, 2004Assignee: Neumag GmbH & Co.Inventor: Diethard Huebner

Publication number: 20040190962Abstract: A printer provided with a unit for forming an image and an endless intermediate belt trained under tension around rollers in such manner that the belt can rotate over the rollers, the intermediate belt being operatively connected to the said unit for transfer of the image from the unit to a receiving material, wherein the belt comprises a fabric of threads as a support, the threads of the fabric being so positioned that when the intermediate belt rotates, a deviation of said belt axially is substantially independent of the tension.Type: ApplicationFiled: March 25, 2004Publication date: September 30, 2004Inventors: Franciscus M.G. Van Den Kerkhof, Maurice G.M. Wilms
