Abstract

Process consists in the deposition of thermoplastic or thermohardening powders, by an electrostatic gun, on the hair side of the skin, which may have undergone treatment with a dye or to improve its electrical conductivity. During currying, quaternary ammonium salts, partic. the halides, may be added, also by means of a spray gun. The machine consists of three conveyors; the leather is conveyed through an electrostatic cabinet and a heat treatment chamber. All leathers treated to render them electrically conducting and able to resist the high polymsn. of fixation temps. can be finished successfully in a continuous manner. The powders can include pigments and/or non-voltatile plasticisers; they are based on epoxy resins, P.V.C., polyethylene, polypropylene, cellulose acetate-butyrate, chlorinated polyethers, polyesters and polyamide resins.
