METHOD OF IMPREGNATING POROUS ABRASIVE ELEMENTS FOR USE IN DISTRESSING FABRICS

摘要

A method of preparing porous abrasive rock for use in distressing fabric, including the steps of impregnating rocks placed in a vacuum vessel (11) with a bleaching solution (15) under reduced pressure, maintaining the reduced pressure for a first interval while injecting the solution beneath the rocks and then increasing the vessel pressure above ambient for a second interval prior to removal.
