RAPID SOLE LEATHER TANNAGE USING DOMESTIC MATERIALS
Abstract
The problem of providing domestic replacements for imported tanning materials in the manufacture of heavy leather is discussed. Previous studies undertaken mainly to cover military emergency requirements are reviewed. A new approach taken by the Quartermaster Corps came AFTER A THOROUGH EXPLORATION OF THE TANNING PROPERTIES OF ALIPHATIC ALDEHYDES. These studies culminated in the development of an original rapid-tanning process for sole leather using glyoxal and formaldehyde in fairly concentrated solutions of mild alkalies, followed by the fixation of lignosulfonates from heated liquors. Bleaching and loading operations were conventional, except that no imported extracts were used. The entire tanning process requires only 3 to 4 days if drums are used throughout (as for insole leather) and about twice as long if the fixation of lignosulfonate takes place in rocker vats. The feasibility of the new process was established by pilot plant runs in 2 tanneries and by wear-testing the leather thus obtained in dress shoes, men's, oxford. The stability of the new leather after prolonged storage under various climatic conditions typical for Army warehouses was also examined.
