Surface treatment of rigid metallic material for cleaning textiles, by ceramicizing or anodizing surface of material to create residual porosity of surface, and impregnating porous surface obtained by bio-based polymers

摘要

The method comprises ceramicizing or anodizing a surface of a rigid metallic material to create a residual porosity of the surface, and impregnating the porous surface obtained by a bio-based polymers having type of antimicrobial, surfactant and/or odor. The ceramicizing step comprises ceramicizing microarcs. The method further comprises shaping the rigid material, and preforming the material by cutting or by thixoforming method. Independent claims are included for: (1) a rigid metal material; and (2) a method for regenerating cleaning properties of rigid metallic material.
