Abstract

163,294. Soc. Pichard FrÞres. May 12, 1920, [Convention date]. Depilation by freezing; treatment preliminary to tanning.-A process for unhairing hides consists in subjecting the hides, after thorough drying, to the action of intense cold at a temperature below -100‹ C. to render the hairs brittle, and whilst still brittle, breaking the hairs off. The hides are momentarily immersed in liquid air, oxygen or nitrogen, and after being drained for a few seconds are scraped or shaved to break off the hairs whilst still frozen and brittle, leaving the roots embedded.
