| titleOfInvention | The use of fine-particulate water-insoluble alkaline aluminium silicates for the washing and cleaning of raw hides and pelts |
| abstract | In the process of washing and cleaning rawhides and fur skins before tanning comprising subjecting rawhides and fur skins to the action of an aqueous solution containing (1) surface-active compounds selected from the group consisting of anionic surface-active compounds, nonionic surface-active compounds and mixtures thereof, (2) emulsifiable solvents for fats and (3) electrolytes, removing said aqueous solution, rinsing, and recovering washed and cleaned rawhides and fur skins, the improvement consisting essentially of employing a fine-particulate, water-insoluble alkali metal aluminosilicate, containing bound water, of the formula (M2O)x.Al2O3.(SiO2)y wherein M represents an alkali metal, x is an integer from 0.7 to 1.5 and y is an integer from 0.8 to 6, said aluminosilicates having an average particle size in the range of from 0.1 to 25 mu and a calcium binding power of from 20 to 200 mg CaO/gm of anhydrous active substance measured at 22 DEG C. according to the Calcium Binding Power Test Method set out in the specification, as partial or total replacement of said electrolyte and optionally partial replacement of said surface-active compounds, whereby the pH of said aqueous solution is maintained between 6.5 and 8.5. |
