Abstract: In a process for manufacturing an interior fitted part for motor vehicles, such as an inside roof lining for automobiles, a staple-fiber formed fabric of a drawn polyethylene terephthalate matrix component and of a binding component is subjected at least once during the process to an annealing process, which increases the thermal stability of the fitted part. Also disclosed is a fitted part manufactured by this method.

Abstract: Disclosed is a flame barrier made of a nonwoven fabric of partially graphitized polyacrylonitrile fibers having a weight per unit area of 40 to 100 g/m.sup.2 and a maximum thhickness of 1.8 mm. The nonwoven fabric is bonded with highly energetic water jets. The flame barrier can be used as a component of a planar multi-layer structure.

Abstract: A multilayer filter pack includes at least three adjacent layers of fibrous material, each of which is permanently electrically charged and not more than 10 mm thick. The upstream and middle layers are formed from fibers having a fiber diameter that decreases from layer to layer in the direction of flow and are arranged at a packing density that increases from layer to layer in the direction of flow. The third layer has a fiber diameter and packing density that is approximately equal to the fiber diameter and packing density of the first layer. The multilayer filter pack is particularly well suited for use in air-purifying systems and breath protection filters.

Abstract: A method is disclosed wherein a nonwoven fabric is synchronously coated with an adhesive composition and impregnated with a radiation cross-linkable binding agent under conditions that render the composition tacky and adherent but not penetrating and that cross-link the agent to at least in part bind the fibers of the fabric.

Abstract: An insole has a capillarily-conductive layer of hydrophobic fibers superimposed on a moisture-storing layer of absorbent fibers with a moisture-permeable bond between the layers.

Abstract: An artificial split suede leather, especially for sport or casual style shoes, is a split, needled, nonwoven material of unshrunk fibers containing at least 20% polyamide fibers by weight of the fibers having a trilobate, Y-shaped cross section. In a process of making it, only needling is used for consolidating the fibers. A spherical filler may also be used.

Abstract: The present invention provides a method for manufacturing a fabric-type artificial leather, wherein a nonwoven fabric is formed by using a dry method to join together hydrophobic fibers. The fabric so formed is densified by needling and the activation of shrinking forces. It is then impregnated with a mixture of a heat sensitive elastomeric bonding agent, powdered barium sulfate and a compound that reacts with acid to form a gas. The impregnated fabric is then exposed to a heated, acidified liquid which triggers coagulation of the bonding agent and liberates a gas formed by reaction of the acid and acid-reactive compound. The resulting solidified fabric is then washed, dried and ground-over on at least one side to produce a nap. Finally, the fabric is intensively fulled.

Abstract: A method for improving the heat retention of a planar textile structure by coating at least one surface of the structure with a dispersion of liquid carrier, cross-linkable binder and metallic powder, and then cross-linking the binder and removing the liquid carrier from the coating.

Abstract: A method for bonding an unbonded fibrous web of natural and/or synthetic fibers by means of a binder which is cured by exposure to UV light, wherein the fibrous web is first compressed, smoothed, and heated, then one or both surfaces of the web is printed with a pattern of a prepolymer binder having a viscosity of from about 500 to 5000 centipoise and the prepolymer binder is cured by exposing the printed fibrous web to ultraviolet light.

Abstract: A hydrophilic foam is produced by mixing an isocyanate terminated branched polyethylene polyol with a polyester prepolymer and water. The foam may be used to impregnate fabrics, e.g., non-wovens, to produce reinforced sheets of foam of high absorbency and markedly improved abrasion resistance. Preferred polyesters are condensation products of adipic acid plus one or more alkanediols or a polylactone. Other prepolymers may also be included in the mix undergoing foaming, along with conventional additives.

Abstract: A breathable lining and shaping material especially suited for garments, comprising a nonwoven layer of randomly arranged fibers superposed on a nonwoven layer of oriented fibers, means holding together the fibers of each layer and holding the layers together, and an outer binder imprinted on the outer face of the oriented fiber layer, the weight of the outer binder being at most 50% of the material weight, the length to width strength ratio of the randomly arranged fiber layer ranging from about 4:1 to 1:4. Advantageously a heat activatable adhesive is provided at spaced locations on the outer face of the randomly arranged layer, whereby the material can be joined to the underside of a garment by hot pressing. The outer binder on the outside of the oriented fiber layer preferably is printed in a regular pattern to ensure that all fibers are tied down by bonds at multiple points.
