Glutaraldehyde retannage of chrome leather. Effect of ambient storage on selected properties of the leather / Edward H. Harris in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXX (Année 1975)

Tannage Résumé : Our previous studies amply demonstrated the valuable properties that glutaraldehyde imparted to leather, especially when used in combination with chrome in the tanning of hides and skins. One of the properties imparted to leather by glutaraldehyde was a markedly improved resistance to perspiration. This was true whether glutaraldehyde was used as the only tanning agent or in combination with chrome or other conventional tanning agents. We found that glutaraldehyde was used to its hest advantage following chrome tanning of leather, since many tanners sort in the blue. However, our previous publications have also shown that applying the glutaraldehyde before, or even simultaneously with, the chrome was at least equally effective. In one of our earlier studies we investigated the effect of elevated temperatures on glutaraldehyde retannage of chrome-tanned sides. In that study the temperature was initially 63°C. and ended at 47°C. As expected, the effect of elevated temperature was to increase the rate of uptake of glutaraldehyde by the chrome-tanned side leather. We now report the results obtained using chrome-tanned cabretta skins in a thermostatted Meissner mill. Because many post-tanning processes, such as retannage, coloring, and fat liquoring, are carried out at about 50°C., we chose this temperature for our studies on retannage of chrome leather with glutaraldehyde. The objective of this study was to determine the quantity of glutaraldehyde and the time of retannage required to attain perspiration-resistance in the chrome leather.

Use of TOC as an alternative to COD for monitoring the biooxidation of tannery unhairing waste / J. E. Cooper in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXV (Année 1980)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. LXXV (Année 1980) . - p. 331-339 Titre : Use of TOC as an alternative to COD for monitoring the biooxidation of tannery unhairing waste Type de document : texte imprimé Auteurs : J. E. Cooper, Auteur ; E. H. Bitcover, Auteur ; E. M. Filachione, Auteur ; J. W. Harlan, Auteur ; David G. Bailey, Auteur ; Stephen H.

Tannage Résumé : A test for chemical oxygen demand (COD), requiring approximately 4 hr, is commonly used to monitor the biooxidation of wastes. A test for total organic carbon (TOC), which requires only 3 to 5 min, was compared with the more time-consuming method to determine if it could be used to estimate the COD test and to monitor the biooxidation. Both TOC and COD were determined for various proteins and amino acids, and the results of the two methods correlated well. The biooxidation of tannery unhairing wastes, complex industrial wastes characterized by high solids content, was monitored by both TOC and COD tests. The results obtained indicate that the TOC test is an acceptable alternative to the COD test when the composition of the waste does not vary significantly with time.
