Publication number: 20010005661Abstract: The inventive method provides highly desirable hand to various different types of fabrics through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or napping of at least a portion of the target fabric. Such a procedure includes “nicking” the immobilized fibers thereby permitting the fibers to produce a substantially balanced strength of the target fabric in the fill and warp directions while also providing the same degree of hand improvements as obtained with previous methods. Furthermore, this process also provides the unexpected improvement of non-pilling to synthetic fibers as the “nicking” of the immobilized fibers results in the lack of unraveling of fibers and thus the near impossibility of such fibers balling together to form unwanted pills on the fabric surface. Fabrics treated by this process are also contemplated within this invention.Type: ApplicationFiled: February 6, 2001Publication date: June 28, 2001Inventors: Louis Dischler, Jimmy B.

Patent number: 5637114Abstract: A process for producing uncoated woven fabrics from synthetic yarn for an airbag comprises the steps of: (a) producing a woven fabric from high tenacity polyester filament yarn having a filament linear density of not more than 5 dtex, a yarn linear density within the range from 250 to 550 dtex, a hot air shrinkage at 200.degree. C. of less than 9% and a boil off shrinkage of less than 2%, (b) washing the fabric at temperatures of less than 60.degree. C., and (c) drying the washed fabric at temperatures of less than 170.degree. C. under conditions so that the dimensions of the fabric, based on its dimensions prior to washing, do not change at all or by less than 2% in warp and weft directions. The uncoated fabric obtained by this process is particularly suitable for making airbags and is notable for good drapability.Type: GrantFiled: January 12, 1995Date of Patent: June 10, 1997Assignee: Hoechst AktiengesellschaftInventor: Gerhard Hohnke

Patent number: 5622766Abstract: Compound threads (1) and the fabrics obtained therefrom are very inexpensive, of acceptable quality and preferably useable to make recyclable disposable garments. Said threads (1) include a thin carrier thread (2) to which a web mass (3) coming from the carding of the fiber used, is adhered preferably by means of use of a water-soluble glue or electrostatic means.The compound thread (1) has the possibility of making use, upon making the web (3), of the shortest fibrils that are usually disposed of.One of the fabrics obtained consists of a band or strip of web (3) that includes several carrier threads (2) placed parallel to each other and that can be cut to obtain compound threads (1.)Another fabric consists of weft thread and crossed warp thread of which all or some, depending on the different combinations, are compound threads (1.Type: GrantFiled: June 10, 1994Date of Patent: April 22, 1997Assignee: TT 1U, S.L.Inventors: Antonio Caballero Rodriguez, Leopoldo Marti Andres

Patent number: H1974Abstract: A papermaker's fabric having a system of primary machine direction yarns which form seaming loops at each end of the fabric and a system of secondary machine direction yarns. A system of cross-machine direction yarns are interwoven with the primary and secondary systems of machine direction yarns in a weave pattern that provides adjacent balancing yarns that maintain the seam loops in substantially vertical alignment.Type: GrantFiled: August 11, 1998Date of Patent: July 3, 2001Assignee: AstenJohnson, Inc.Inventors: Henry J. Lee, Billy Summer
