Patent

CA 2633974

The present invention provides an article formed by impregnating a fibrous structure with a compound, the compound including an aqueous dispersion, the dispersion having (a) at least one polymer selected from the group consisting of an ethylene-based thermoplastic polymer, a propylene-based thermoplastic polymer, and mixtures thereof; (b) at least one polymeric stabilizing agent; and (c) water; and removing at least a portion of the water from the impregnated fibrous structure. The present invention also provides a method of forming a stiffened textile. The method may include the steps of: forming a compound, the compound including an aqueous dispersion having (a) at least one polymer selected from the group consisting of an ethylene-based thermoplastic polymer, a propylene-based thermoplastic polymer, and mixtures thereof, (b) at least one polymeric stabilizing agent, and (c) water; impregnating a textile with the compound; and removing at least a portion of the water from the impregnated textile.

La présente invention concerne un article formé en imprégnant une structure fibreuse avec un composé, ledit composé comprenant une dispersion aqueuse, ladite dispersion comprenant (a) au moins un polymère sélectionné dans le groupe constitué de polymères thermoplastiques à base d'éthylène, de polymères thermoplastiques à base de propylène et de mélanges de ceux-ci ; (b) au moins un agent stabilisant polymérique ; et (c) de l'eau ; et en enlevant au moins une partie de l'eau de la structure fibreuse imprégnée. La présente invention concerne également un procédé de formation d'un textile rigidifié. Le procédé peut comprendre les étapes consistant à : former un composé, ledit composé comprenant une dispersion aqueuse comprenant (a) au moins un polymère sélectionné dans le groupe constitué de polymères thermoplastiques à base d'éthylène, de polymères thermoplastiques à base de propylène et de mélanges de ceux-ci ; (b) au moins un agent stabilisant polymérique ; et (c) de l'eau ; imprégner un textile avec le composé ; et enlever au moins une partie de l'eau du textile imprégné.
