Abstract:
1. A textile two- or three-dimensional structure formed from fibers and/or ribbons and a swellable material, the fibers and/or ribbons in the structure and also the swellable material each being present in such amounts that the fibers and/or ribbons are encased by the swellable material and voids in the structure are, in the swollen state, partially or completely filled by materially bound water, wherein the swellable material comprises an aqueous emulsion comprising a (co)polymer of at least one ethylenically unsaturated monomer which is applied to the fibers and/or ribbons, wherein the emulsion additionally comprises component (A) which is at least one water-soluble polymer selected from the group consisting of (a1) graft polymers of vinyl acetate and/or vinyl propionate on polyalkylene glycol or one- or both sidedly alkyl-, carboxyl- or amino-substituted polyalkylene glycol, (a2) copolymers of alkylpolyalkylene glycol (meth)acrylates and (meth)acrylic acid, (a3) polyalkylene glycols, and (a4) one- or both sidedly alkyl-, carboxyl- or amino-substituted polyalkylene glycols, and component (B) which is at least one water-soluble polymer selected from the group consisting of (b1) hydrolyzed copolymers of vinyl alkyl ethers and maleic anhydride as a free polyacid or at least partially neutralized with alkali metal hydroxides or ammonium bases, (b2) modified or unmodified starch, and (b3) synthetic copolymers obtainable by copolymerization of monomers, the molar fraction of cationic monoethylenically unsaturated monomers (β2) interpolymerized in (β3) being higher than the fraction of interpolymerized anionic monoethylenically unsaturated monomers (β3), and wherein the emulsion is obtained by (co)polymerizing said at least one ethylenically unsaturated monomer in the presence of components (A) and (B).
