Patent

CA 2285064

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 multi--functional 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.

La présente invention concerne une pâte gonflante imprimable à un seul composant à base d'un mélange aqueux d'un polymère soluble dans l'eau à teneur en groupes carboxyles, d'au moins un alcool multifonctionnel comme agent de réticulation et éventuellement d'autres agents d'addition tels que les agents épaississants, les groupes carboxyles du polymère étant neutralisés à raison de 40 à 65 % en pourcentage molaire. L'invention concerne également l'utilisation de la pâte gonflante dans la fabrication de fils, tissus, textiles non tissés ou films. Après application de la pâte gonflante sur le support, on procède à un retraitement thermique aux fins de séchage et de réticulation de ladite pâte gonflante.
