New products manufactured by Farbwerke vorm Meister Lucius & Brüning, Hoechst on the Main, Germany. . ial is given four or six ends— bath should be clear yellow and the goods should be the same color as they come from thebath. The goods after dyeing are squeezed out, oxidized by a skying arrangement thenwashed and soaped or chromed. \\\ Raw Cotton, Cops and Spools in machines. The vat liquor is made up according to the desired shade and the material dyed accordingto the method necessary for the kind of machine. After dyeing the color must be developed withoxidizing agents, bichromate being the most available. The dyed material is treated for onehalf hour at 140° F. with 1 to 2 per cent Bichromate \ to 1 per cent Acetic Acid and then thorough-ly washed and dried. Raw Cotton can also be dyed in an open kettle if this is fitted with squeeze rolls. On account of its affinity for vegetable fibres which is much greater than that of Indigo,the baths are exhausted much better and the dyeing operation rendered much simpler as anydesired shade can be obtained in one run. • No. r.
