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.
