Résumé : |
A tannery-scale trial of the sulfite acetic acid method for short-term preservation of hides developed at our laboratory was carried out at the Seton Leather tannery. Fresh, washed, fleshed hides (4,500 lb) were treated in a wooden tannery drum and fresh, washed, unfleshed hides were treated in a lined hide processor in two runs (10,750 and 15,000 lb).
The hides were stored in containers that were lightly covered with plastic for three days at ambient temperatures of approximately 70°F. Microbial counts carried out on samples cut from the hides showed that microbial control was maintained. Hides from the forst two tests were processed into shoe upper leather of good quality, but of slightly lower weight than normal production. Washing and addition of alkali before the hides were unhaired and limed corrected this condition in the third test. Control of the odor of sulfur dioxide is necessary for the adoption and practical use of this method of preservation. |
