| titleOfInvention | Improvements in processes of bleaching and dyeing furs |
| abstract | 265,324. Dehn, F. B., (Stein Fur Dyeing Co., Inc.). Nov. 25, 1925. Bleaching, processes and materials for.- Animal fibrous materials, such as furs, are bleached rapidly, without weakening the leather of the skins or impairing the natural texture and strength of the hair, and may be dyed subse. quently to light or other colours, if first treated with ferrous salt (e.g. porous sulphate) as a protective agent, with or without ammonium chloride as a stabilizing agent. Thus the fur skins may be washed three hours with an alkaline solution, e.g. sodium carbonate, and then soaked in an aqueous solution containing from 0.5 to 5.0 per cent by weight of ferrous sulphate, with a similar amount of ammonium chloride, after which they are rinsed and hydro-extracted, prior to immersion in a bleaching solution such as a 3 to 5 per cent by volume solution of hydrogen peroxide. Ultimately they are washed and dyed by any suitable process, with or without mordanting. The method may also be applied to skins previously unsatisfactorily dyed. Specification 264,969 is referred to. |
