CONTROLLED IMPREGNATION COATING OF COMPRESSIBLE MATERIAL SUCH AS OPEN CELL FOAM

摘要

(Figure 1a) Title: Controlled Impregnation Coating of compressible material such as open cell foam A method and apparatus for the economical production of such like as a cleaning or scouring product based on application of a substance to a foam material in which the substance is applied to the material whilst it is compressed (between rollers B, C) with application being first to one of the rollers and then transferred to the material, and thereafter cured/dryed. The resulting foam material having a surface which is uneven and presenting recesses at incomplete cell-sites open at that surface with the application and penetration of said substance or a material borne by said substance causing the surface to have the disused cleaning or scouring properties.
