This invention relates to a bonded fiber web capable of absorbing water vapor and composed of synthetic, natural or regenerated fibers with a uniformly incorporated additive of at least one polymer, said additive comprising fibrous particles of at least one swellable carbohydrate derivative or a swellable modified carbohydrate derivative. The invention also relates to a process for the manufacture of the bonded fiber web.

In a bonded fiber web capable of absorbing water vapor and composed of synthetic, natural or regenerated fibers with an uniformly incorporated additive of at least one polymer, the improvement comprising about 3 to 70% by weight, relative to the total fiber proportion, of said additive which comprises fibrous particles of at least one swellable cellulose ether, which has been modified by crosslinking, effected by means of heat energy, radiation, or an additional chemical compound and which is insoluble in water to the extent of at least about 30% by weight. In the process for the manufacture of a bonded fiber web capable of absorbing water vapor and composed of synthetic, natural or regenerated fibers with an uniformly incorporated additive of at least one polymer, the improvement comprising (a) adding to the synthetic, natural or regenerated fibers, before or during the manufacture of the web, about 3 to 70% by weight, relative to the total fiber proportion, of fibrous particles of at least one swellable cellulose ether, which has been modified by crosslinking, effected by means of heat energy, radiation, or an additional chemical compound and which is insoluble in water to the extent of at least about 30% by weight, (b) incorporating said fibrous particles uniformly therein, (c) bonding the fiber web, and (d) drying it after bonding.
