Abstract:
A variety of embodiments are disclosed, in both apparatus and method form, that relate to the use of fabric material in the manufacture of an air bag deployment system. In addition, fabric weakening is disclosed according to a technique that does not result in physical alteration of the fabric. This invention therefore includes an air bag cover for an air bag safety system for a vehicle comprising a fabric outer layer having a frontside and a backside and a substrate containing an opening wherein the opening has a periphery. The substrate is preferably formed by low pressure molding, wherein the fabric outer layer overlies the opening in the substrate, and wherein the fabric outer layer is weakened at a location that is adjacent or overlies the substrate opening periphery.

Abstract:
A reversible, heat-set covered fiber is described, the covered fiber comprising: A. A core comprising an elastic fiber comprising a substantially crosslinked, temperature-stable, olefin polymer, and B. A cover comprising an inelastic fiber. The fiber is head set by a method comprising: (a) Stretching the covered fiber by applying a stretching force to the covered fiber; (b) Heating the stretched covered fiber of (a) to a temperature in excess of the crystalline melting point of the olefin polymer for a period of time sufficient to at least partially melt the olefin polymer; (c) Cooling the stretched and heated covered fiber of (b) to a temperature below the crystalline melting point of the olefin polymer for a period of time sufficient to solidify the polymer; and (d) Removing the stretching force from the covered fiber.
Abstract:
A tent fabric comprising a woven fabric made of yarns containing kenaf fibers in an amount of 10 wt. % or more. The tent fabric after use can easily be recycled and hence contributes to resource saving and environmental protection.
Abstract:
A plane formed body, especially a floor covering, is described with a cover layer (1), a base layer (3) and a core layer (2) that have fibers that can be stitched. The three layers are stitched by means of fibers (1a) taken from the cover layer (1). The core layer (2) consists of polyvinyl chloride material in the form of pieces that are in solid form and a PVC binder or plastisol paste. The fibers (1a) are tightly bonded into all three layers (1,2,3).
Abstract:
A process of making a cut pile, tufted carpet that has the tightly curled appearance of Persian lamb is dislcosed. It comprises the steps of:(a) knitting a synthetic carpet facing yarn, e.g., a continuous filament nylon, into a deknittable fabric,(b) heating the fabric to a temperature at which the curves and bends generated in the yarn by its knitted configuration are established in the yarn's memory,(c) cooling the fabric to about room temperature,(d) deknitting the cooled fabric and rewinding the unravelled yarn under enough tension to restraighten it,(e) tufting the yarn as facing yarn into a primary carpet backing material, forming a cut pile carpet, which then can be dyed,(f) coating the underside of the carpet with a heat-settable adhesive that, when cured, will help anchor the tufts of yarn in the backing material, and(g) heating the adhesive-coated carpet to a temperature at which the adhesive will set and the facing yarn will reconform to the bends and twists in its memory.
