The invention relates to a printable one-component swelling paste made of an aqueous mixture of a water-soluble polymer containing carboxyl groups, and at least one multifunctional alcohol as crosslinker and optionally further additives such as thickeners, the carboxyl groups of the polymer being neutralized to 40-65 mole-%. The invention also relates to the use of the swelling paste for producing water-swellable yarns, fabrics, nonwovens, or films. After coating the swelling paste on a support, a thermal subsequent treatment is effected for the purpose of drying and crosslinking the swelling paste. |
