<p>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.</p> |
