摘要：
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.
