titleOfInvention | Tanning process |
abstract | In a process for the complete tanning of material such as animal hides, pelts, fur skins and furs, and the re-tanning of leather, the material is treated with between 1 and 30% of its weight of a methylol derivative of a mononuclear phenol or a binuclear phenol compound containing, in each nucleus, not more than one phenolic hydroxyl group, and being free from anionic groups and condensed rings, in a weakly acidic to weakly alkaline aqueous solution, e.g. having a pH between 6 and 9. The solution may contain up to 50%, by weight of a water-soluble organic solvent, such as methanol, ethanol and acetone. Suitable derivatives are: mono-, di- or polymethylol derivatives of phenol, cresols, xylenols, thymol, carvacrol, halophenols, phenylphenols, monohydroxy- and dihydroxy-diphenylmethanes, dihyroxy-diphenylpropanes. Particularly suitable derivatives are: monomethylol- and dimethylol-4, 4' dihydroxy-diphenyl sulphone. missing page 170 |
