Abstract
To obtain very fine threads from viscose by the drawing-out process, the viscose used is prepared from a "very weak hydrated cellulose," and the original relatively-thick threads are stretched while undergoing coagulation, in a slowly-acting precipitating-liquid, such as a one per cent sulphuric acid solution. After leaving the coagulating-bath the threads are wound on reels revolving in a 2-4 per cent solution of sulphuric acid, by which they are finally hardened.
