Title: Improvements in or relating to solvent tanning and chamoising fur skins and hides
IPC: C14C3/04
Filed: 1965-05-12
Abstract: In solvent tanning, chamoising and/or fatliquoring fur skins and hides to yield furs and leather for wearing apparel, such as gloves and linings, the fur skins or hides, preferably soaked, are placed in a perforated drum, e.g. of a known automatic, chemical or solvent cleaning machine, which drum is rotated in a bath containing a water-miscible organic liquid solvent, such as acetone, methyl alcohol or ethyl alcohol, so that the fur skins or hides are intensely agitated in the solvent, which effects dehydration.  The solvent is then drained off, and the rotational speed of the drum is increased, so that the fur skins or hides are spin-dried.  The speed of the drum is then reduced.  These dehydrating operations may be repeated using fresh solvent at each repetition. A tanning liquor comprising a tanning agent in the form of a complex compound having the general formula:  <TABS:1093889/C6-C7/1> Alk is an aliphatic alcohol with five to thirty carbon atoms and at least one OH group in its molecular chain, such as a stearyl alcohol complex of chromic chloride or zirconium tetrachloride dissolved in a water-miscible organic liquid solvent containing a chamoising and/or fatliquoring agent, such as sulphated rape seed oil, ricinous oil or an alcoholized fat, and, if desired, hexamethylene tetramine, is fed into the bath, so that the fur skins or hides become saturated with tanning liquor. The tanning luquor is then drained off and the speed of the drum is increased, so that the resulting furs or leathers are spin-dried, and the speed of the drum is then reduced.  These tanning operations may be repeated using fresh tanning liquor at each repetition.  Hot air at a temperature between 60 and 65 DEG C. is then passed through the drum to effect final drying of the furs or leathers.  Before final drying, another organic solvent, having a lower boiling point than water, and forming an azeotropic mixture with water and the original solvent, may be added to the final tanning liquor, so that, when final drying takes place, water evaporates before the other components of the mixture.  The resulting furs and leathers may be moth-proofed and dyed.
