| Abstract: | The technology of chrome tanning under the supercritical carbon dioxide fluid (SCF - CO2 ) was studied by using self - made supercritical carbon dioxide fluid equipment, in order to illustrate the influence of the entrainer A and reaction time to this new chrome tanning method. The tanning effects were evaluated by the shrink temperature and chrome content of the tanned leather. The results shown that the optimum dosage of entrainer A for SCF ?CO2 chrome tanning was 8 % , which was based on the weight of pickling hide, and that the optimum tanning time was 1 hour. |
