Abstract

Dressed or undressed leather tanned by any process is saturated with a solution of sodium sulphide and sodium thiosulphate, the penetration and degreasing effect of which may be accelerated by the addition of caustic soda or other caustic alkali, and is then treated, preferably in another bath, with hydrochloric, sulphuric, or other inorganic or organic acid, sulphur being thereby deposited in the leather. The process is stated to soften hard grained or brittle leathers producing a velvet effect, also to decolorize or clear stained or darkened tanned or retanned leathers, and may be used for finishing or in preparation for dyeing. It may be used in place of or in conjunction with vegetable retanning, for cleaning after chrome tanning, and for degreasing dressed or undressed chrome or other leathers.
