contributes.. Stretch Nylon covers the fashion scene today from men's hose to women's swim suits. Color-fast dyeing of this yarn is tricky and calls for the unique fixative action of a superior tannic acid. Newly improved Mallinckrodt Tannic Acid T8 is the tannin for this critical application. Lowest in insolubles, lightest in color . . . . Reduced insolubles content of the newly improved Mallinckrodt Tannic Acid T8 eliminates the danger of spotting . . . insolubles will not filter out, even in package dyeing. The exceptional clarity of Tannic Acid T8 solution permits working with modern light shades, not previously possible. And the extremely low level of trace metals in Mallinckrodt's T8 insures negligible interference with other dye bath components. Lowest in real c o s t . . . .
