Abstract

167,785. Manvers, A. Feb. 14, 1920. Tanning under pressure; tanning and treating in vacuo.-Hides, preferably after being subjected to a high vacuum, are tanned under pressure by liquor from which all air has been removed. Treatment with thin glue or gelatine may follow. The depilated and preferably dried hides are suspended in an autoclave and subjected for thirty to sixty minutes to a high vacuum, a strong tanning-liquor from which all air has been removed by passage through a vacuum machine &c., being then pumped in, preferably under a pressure of from 20 to 40 lb. per sq, in. After the tanning-liquor has been run off, the hides are washed and a solution of thin glue or gelatine is forced into the pores by alternate high vacuum and high pressure. The hides may be again washed and are dried in vacuo, small quantities of hot air being admitted, preferably through a red-hot pipe.
