Abstract

The salts carried by or formed on the threads after leaving the acid precipitating-bath are recovered and utilized by washing the threads with dilute sulphuric acid so as to form the very soluble bisulphate of soda or potash, and then returning the resulting acid salt solutions, after concentration, to the precipitating-bath. For the washing a 10-12 per cent sulphuric acid solution is preferably employed.
