摘要

"PROCEDURE FOR THE MANUFACTURE OF AN OBJECT FOR CLEANING BASED ON IMPREGNATED FIBERS IN QUARTZ POWDER THROUGH AN ADHESIVE", characterized in that the effect uses a fiber fleece of coarse texture, preferably made of synthetic material, which impregnate in melamine or phenolic resins and/or the so-called hard resins containing in suspension a large amount of very fine silicic oxide powders, which remain strongly adhered to the fibers by virtue of the contraction and drying by condensation of the resins, after a thermal treatment with temperatures above one hundred degrees.
