Printable swelling paste and the use thereof

摘要

The invention relates to a printable swelling paste which contains 1. polymers having carboxyl and amide group moieties, and 2. an aldehyde or an aldehyde-liberating compound as components of the mixture. Optionally, the mixture may contain further additives, such as thickeners. The polymer component having carboxyl and amide groups is produced by free-radical copolymerization of monomers containing amide groups and monomers containing carboxyl groups, and other comonomers may be polymerized therein as well. The invention also relates to the use of said swelling paste in the production of absorbent fibers, fabrics and sheet materials such as films by applying the swelling paste onto the support material and subsequent thermal treatment.
