Abstract: A process for the pretreatment of textile material consisting entirely or partially of cellulose fibers and which is to be printed according to the thermotransfer process, which comprises impregnating the textile material with a solution or dispersion containing(a) a compound of the formula INH.sub.2 --CO--Y--R (I)wherein R stands for a group of the formulae R.sub.a, R.sub.b or R.sub.c ##STR1## in said formulae R.sub.1 is hydrogen or C.sub.1-4 alkyl, R.sub.2 is C.sub.1-4 alkyl, R.sub.3 is hydrogen or methyl, n is an integer of from 1 to 6, m is an integer of from 1 to 10, X is CH.sub.2 or O and Y, in case that R stands for R.sub.a or R.sub.b is an oxygen atom and in case that R stands for R.sub.c is an oxygen atom or an imino group (NH),(b) a glyoxal or melamine formaldehyde resin and(c) an acid catalyst for the condensation of these resins, and subsequently drying the textile material and subjecting it to the action of heat.

Abstract: A process for the pretreatment of cellulose fibers which are printed according to the thermotransfer printing process, which comprises impregnating the fiber material with a solution or dispersion containing a compound of the formula ##STR1## in which x is 2 or 3, A represents--if x=2--a group of the formula ##STR2## or -if x=3 --represents a group of the formula ##STR3## W is a group of the formula --CH.sub.2 --or ##STR4## R is hydrogen or methyl, m is a number of from 1 to 30, preferably from 4 to 11, and n is a number of from 1 to 30, preferably from 1 to 10, as well as a polymerization catalyst, and steaming and drying the material.

Abstract: This invention relates to a process for preparing swellable cross-linked carboxyalkylcelluloses by reacting cellulose, a carboxyalkylating etherifying agent, and a cross-linking agent in an aqueous alkaline medium, comprising effecting alkalizing, etherifying, and cross-linking simultaneously in one reaction step using fibers, textile sheet materials containing these fibers, or sheet materials of other kinds, having a base of cellulose hydrate or of natural cellulose, by contacting said fibers or sheet materials with an ample quantity of an aqueous alkaline reaction mixture, removing part of the reaction mixture from the fibers or sheet materials contacted therewith, so that at least the quantity required for reaction is still present, and treating the fibers or sheet materials containing the remainder of the aqueous alkaline reaction mixture with heat energy. The invention also relates to equipment for performing the process.

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: Process for improving the water-absorbing capacity and absorptivity of fibrous materials consisting of, or containing, synthetic fibers or filaments, which comprises applying modified, highly absorbing cellulose ethers onto the fibrous materials and fixing these cellulose ethers on the fibrous material with the aid of finishing agents, resins or binders.

Abstract: Process for the transformation of comminuted and modified cellulose ether swellable with water, into a material that may easily be further processed and may thus be used without difficulty in particular in the production of hygienic pads, napkins, bandages, tampons, wrapping papers, insulating material, household papers and similar articles. In said process the modified cellulose ether is attached by electrostatic flocking to at least one surface of a web-shaped hydrophilic support that has been wetted with water and the support is dried.

Abstract: A process for the manufacture of electroconductive non-woven fabrics which comprisesA. cleaning the fabrics with a polar organic solvent and, after elimination of the solvent,B. sensitizing them with an aqueous hydrochloric acid solution of tin-II chloride,C. activating them with an aqueous hydrochloric acid solution of palladium chloride, andD. treating them with a mixture of a tenside-free binder dispersion and a metastable aqueous metal salt solution, and subsequently drying them; the fabrics being rinsed with water after each of the steps (b) and (c) is provided.
