Abstract: 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.

Abstract: This invention relates to an improvement in the process for the manufacture of modified starch ethers in which, prior to, during, or after etherification, a reaction with a modifying agent is conducted in a wet alkaline medium, the improvement comprising that, if etherification were the only reaction conducted, an at least preponderantly water-soluble starch ether would be formed, and the modification results in an absorbent modified starch ether more than 40 per cent by weight of which is insoluble in water.

Abstract: Process for the transformation of comminuted cellulose ether, which has been rendered at least largely water-insoluble by modification but is still highly swellable with water, into an easily workable material, comprising wetting a hydrophilic support web, applying the comminuted modified cellulose ether to the wetted web, and drying. This invention also relates to an apparatus for performing the process.

Abstract: This invention relates to a process for the manufacture of absorptive polymers which are at least preponderantly insoluble in water, but capable of swelling in water, which comprises etherifying polyhydroxy methylene in a homogeneous phase in an aqueous alkaline solution with an alpha -halogen carboxylic acid, and prior to, during, or after the etherification process performing a further reaction with a cross-linking agent which is polyfunctional towards polyhydroxy methylene in an alkaline medium.
