Title (EN) METHOD FOR CLEANING SOLID MATERIALS AND APPARATUS FOR APPLYING THIS METHOD
(FR) PROCEDE DE NETTOYAGE DE MATIERES SOLIDES ET APPAREIL METTANT EN OEUVRE LEDIT PROCEDE
Abstract: front page image
(EN)In a method for cleaning solid materials, in particular textile products, the surface of said materials in a solvent brought into a near-critical condition, preferably near-critical CO¿2?, is contacted with a surfactant. The cleaning action of the surfactant is achieved by varying the pressure in the solvent with a frequency preferably in the order of 0.1 to 10 Hz.
(FR)La présente invention concerne un procédé de nettoyage de matières solides, notamment de produits textiles, dans lequel la surface desdites matières dans un solvant porté à un état voisin de l'état critique, de préférence voisin de l'état critique CO¿2?, est mise en contact avec un agent tensioactif. L'action nettoyante du tensioactif est obtenue en faisant varier la pression dans le solvant à une fréquence de l'ordre, de préférence, de 0,1 à 10 Hz.
