Título
(EN) PROCESS FOR TREATING LINENIZED CORK SHEETS
(FR) PROCEDE DE TRAITEMENT DE FEUILLES DE LIEGE TOILEES
Resumen
(EN)
A process for treating linenized cork sheets, employing at least one emollient agent comprising surfactants, allows the obtainment of crease-resisting sheets that can be folded like fabric and comprises the steps of diluting said at least one emollient agent with water, in a predetermined proportion water/emollient agent, obtaining an emollient mixture; preparing an absorbing layer sheet, to be soaked with liquid, and inducing the absorption of said emollient mixture in said layer; putting in contact said soaked layer (1) with a linenized cork sheet (2) at its linenized surface (3), keeping this contact for more than 24 hours.
(FR)
On décrit un procédé de traitement de feuilles de liège toilées qui utilise au moins un agent émollient comprenant des tensioactifs. Le procédé permet d'obtenir des feuilles infroissables pouvant être pliées comme du tissu, et consiste à diluer ledit agent émollient dans l'eau dans une proportion eau/émollient préétablie pour obtenir un mélange émollient. Le procédé consiste ensuite à préparer une feuille à couche absorbante en l'imbibant de liquide, puis à laisser cette couche absorber le mélange émollient. Le procédé consiste enfin à mettre ladite couche imbibée (1) au contact de la face toilée (3) de la feuille de liège (2), puis à maintenir ce contact pendant plus de 24 heures.
