    Abstract: An absorbent material is provided having exceptional fluid suction and holding power for aqueous physiological fluids, and which is thus especially adaptable for use as tampons, sanitary napkins, baby diapers, hospital pads and the like. The material consists essentially of cellulose fibers containing from 5 to 20% by weight of sodium carboxymethyl cellulose. The material is formed by a process in which a viscose spinning solution is produced from cellulose xantogenate by dissolving in aqueous caustic soda solution and permitting the solution to ripen, spinning the latter in an acid spinning bath, and then cleaning and drying the resultant threads, the spinning solution containing 5 to 20% by weight of sodium carboxymethyl cellulose.

    Abstract: This invention relates to a process for coating the surface of a shaped article of cellulose hydrate with a layer of polymer material which comprises applying to the surface of a shaped article in the gel state and based on cellulose hydrate, a liquid layer of an aqueous solution of a chemically modified protein obtained by mixing an aqueous alkaline protein solution with an aqueous solution of N-methylolacrylamide or N-methylol-methacrylamide or of the alkoxy derivatives thereof of aliphatic alcohols with 1 to 8 carbon atoms, particularly of organic, tetrafunctional, doubly unsaturated compounds of the general formula ##STR1## in which R.sub.1 and R.sub.2 are hydrogen or an alkyl group with 1 to 6 carbon atoms, andR.sub.3 is the group --(CH.sub.2).sub.n --, n being an integer from 1 to 8, or the group ##STR2## in which R.sub.4 is an alkyl group with 1 to 18 carbon atoms, subjecting the liquid mixture to a dwell time, heating the coated shaped article, and wetting the shaped article. The invention also relates to a shaped article of cellulose hydrate having a coating of protein thereon.
