Abstract: A non-woven fabric (1) that is modified with activated carbon is needled on an elastic or inelastic textile sheet material (2), preferably a woven fabric or a knitted fabric. With this method, it is achieved that the strength of the textile sheet material (2) can be imparted to a non-woven fabric (1) that is otherwise not tear-resistant, whereby the adsorption properties of the activated carbon that are necessary in protective textiles are completely retained. During needling, the elastic or inelastic textile sheet material (2) is stretched or kept stretched, and stress is relieved after needling. The effect that is thus achieved is that the non-woven fabric (1) does not tear when the textile good or the molded part is stretched again, since the non-woven fabric then is stretched out from a compressed initial state.

Abstract: The present invention provides a multilayer multiaxial woven fabric for a papermachine having a reduced interference pattern and accordingly improved dewatering uniformity. The present invention also provides a method of forming such multilayer multiaxial fabric.

Abstract: A non-woven fabric (1) modified by activated carbon is needled onto an elastic or inelastic textile sheet material (2), preferably a woven fabric or a knitted fabric. By this method, the strength of the textile sheet material (2) can be imparted to a non-woven fabric (1) that is otherwise not tear-resistant, wherein the adsorption properties of the activated carbon necessary for protective textiles are completely retained. The elastic or inelastic textile sheet material (2) is stretched or retained stretched while the non-woven fabric is needled on and is relaxed after the non-woven fabric has been needled on. The effect thereby achieved is that the non-woven fabric (1) does not tear if the textile good or the molded part is stretched again, because the non-woven fabric is then stretched from a compressed initial state.

Abstract: A method for manufacturing an artificial leather comprises the following steps. First, ultramicrofiber-forming fibers having an islands-in-sea type cross-sectional configuration are formed by blend spinning or conjugate spinning. Secondly, a porous reinforcement sheet of low compactness is formed from polyester, polyurethane or polyolefin by spunbonding, meltblowing or calendering. Next, the ultramicrofibers are entangled with the reinforcement sheet by needle punching or spunlace to form the complex reinforced ultramicrofiber nonwoven fabric. The nonwoven is impregnated or coated with an elastomer resin composition, and then subjected to a coagulating process, a washing process, a drying process and a removing process to produce a semi-product leather. Finally, the semi-product leather is then processed to produce the artificial leather.
