A working model of the machine is being demonstrated here by William M. Wentz, right, inventor of the machine and G.T. Hug, both of the company's Dyestuffs Division. The fabric enters at right and is carried into and out of the dye bath a number of time by means of multiple laps around an endless conveyor, which subjects it to a minimum of stretching or distortion. The cloth finally emerges from the center of the apparatus.

- Description
-
The upper strip is a fastness test record of a vat dye the lower strip a direct dye. The white swatches are undyed materials used in the test to demine whether the dye bleeds onto the adjacent material. If these fabrics are examined carefully, comparison of the equivalent test on each of these colors will quickly demine their relative fastness.

This image shows a section of the vat color chemical control laboratory at the dye works. Vat colors are the fastest coloring agent known to modern science and are used on cotton, viscose process rayon and linen. In general, these colors are the fastest because of their inherent characteristics and the nature of their combination with the fibers colored. In themselves, vat dyes are outstanding in their resistance to such color destroying influences as light laundering, acids and alkalites....
Show moreThis image shows a section of the vat color chemical control laboratory at the dye works. Vat colors are the fastest coloring agent known to modern science and are used on cotton, viscose process rayon and linen. In general, these colors are the fastest because of their inherent characteristics and the nature of their combination with the fibers colored. In themselves, vat dyes are outstanding in their resistance to such color destroying influences as light laundering, acids and alkalites. They are insoluble in water and therefore cannot 'bleed'. When applied they are rendered soluble by chemical means, and this solution enters the fiber to be colored. The color is then oxidized with an oxidizing agent and the dye brought back to its original insoluble form. Thus, the dye become a permanent part of the fiber.
