(FR) NON-TISSES POUVANT SE DISPERSER DANS L'EAU ET CONTENANT DES MATERIAUX LIANTS POLYMERES SENSIBLES A LA TEMPERATURE OU AUX IONS, ET PROCEDE DE FABRICATION ASSOCIE
Abstract
(EN)
The present invention is directed to a temperature-sensitive or ion-sensitive binder composition containing at least one temperature-sensitive or ion-sensitive polymeric material. The binder composition is either (1) insoluble in water containing greater than about 0.5 weight percent monovalent ions or water having a multivalent ion concentration greater than about 200 ppm multivalent ions, and soluble in water containing less than about 0.5 weight percent monovalent ions or water having a multivalent ion concentration less than about 200 ppm multivalent ions; or (2) insoluble in water having a temperature of greater than about 30 °C, and soluble in water having a temperature of less than about 25 °C. The present invention is further directed to a water-dispersible nonwoven fabric containing the temperature-sensitive or ion-sensitive binder material, which is useful in the manufacture of flushable personal care products. A process for making water-dispersible nonwoven fabrics is also provided.

L'invention concerne une composition liante sensible à la température ou aux ions, et contenant au moins un matériau polymère sensible à la température ou aux ions. Cette composition liante est soit (1) insoluble dans une eau contenant une quantité supérieure à environ 0,5 % en poids d'ions monovalents, ou dans une eau possédant une concentration ionique supérieure à environ 200 ppm ions multivalents, ou soluble dans une eau contenant une quantité inférieure à environ 0,5 % en poids d'ions monovalents, ou dans une eau possédant une concentration ionique supérieure à environ 200 ppm ions multivalents; soit (2) insoluble dans une eau dont la température est supérieure à environ 30 °C, et soluble dans une eau dont la température est inférieure à environ 25 °C. L'invention concerne en outre un non-tissé pouvant se disperser dans l'eau, contenant un matériau liant sensible à la température ou aux ions, et utile dans la fabrication de produits hygiéniques jetables dans les toilettes; elle concerne encore des non-tissés pouvant se disperser dans l'eau.
