TREATMENT OF HIDES

摘要

A process and apparatus for treating animal skins or hides (10) comprises stretching the hide to extend it and to open the structure, and mounting the hide in a frame (15) by ties (12) extending between hide edge attachments (11) and the frame. The hide (10) while in the frame passes through multiple process operations involving sequentially applying treatment fluids under pressure. A pressure differential maintained across the hide thickness enables the fluids to pass through the flesh surface (10a) and emerge from the grain surface (10b). The hide (10) can be supported on a porous backing membrane (45) during treatment. The treatment fluids are collected and processed for recycling, recovery of by-products and disposal.
