An Improved Method and Apparatus for Treating Textile Fibrous Materials with the Products of the Electrolysis of Water Solutions of Acids, Oxides and Salts.

摘要

2083. Hey, H. Jan. 27 Cells and receptacles have their electrodes &c. specially arranged to increase the efficiency of the current in the treatment of fibrous materials, in cleansing, bleaching, extracting, carbonizing, dyeing, stripping or removing dye, disinfecting, or sterilizing. A grid 2 of suitable material is covered on one or more surfaces with an electrode 3 of lead, zinc, tin, aluminium, carbon, or other suitable conductor, placed above or below it and connected to the current source by a wire 4 insulated by a glass tube 5 or the like. The other electrode 6 may be formed similarly, and is removable from the vessel. The fibrous material is placed between the two grids in a suitable liquid during electrolysis of the liquid. The products evolved at the lower electrode diffuse through the fibrous material. A four-pole switch may be used to reverse the current when necessary. The electrolyte may be a suitable acid, or oxide or salt of a metal, e.g. chromium, vanadium, manganese, titanium, iron, copper, and the like. A steam-heated pipe 8, Fig. 1, may be used to assist the circulation. The liquid may be cooled by a water-pipe coiled round the interior of the vessel, or led straight across, near the surface, and insulated, so as to serve as the top electrode,
