APPLICATION OF VAT DYES: dyebath so that the dye can exhaust on to the fabric surface. Low liquor ratios and the addition of common salt or Glauber's salt both promote such exhaustion. In some cases, the addition of acid also promotes exhaustion. If the dye is only partially soluble in water and likely to be exhausted unevenly, the addition of soap or sodium carbonate may promote leveling. A dyeing is considered to be level if all parts of all fibers have been penetrated evenly and completely. Machines for this type of dyeing are called batch machines. · Package and beam machines for yarns. · Jigs for open width fabrics · Winches for woven and knitted fabrics in rope form · Jet dyeing machines for knitted fabrics in rope form. · Paddle machines for sewn products like bedspreads · Smith drums for nylon hosiery or special machines for nylon hosiery

The Chemistry and Manufacture of Vat Dyes: Vat dyes, which include indigo and anthraquinone-based dyes, are chemically complex dyes which are insoluble in water. They must first be reduced to the leuco form in an alkaline solution of sodium hydrosulfite before application to the cotton or rayon fiber. Air oxidation fixes the dye strongly on the fiber, resulting in excellent wash-fastness and light-fastness. The vat dyes were one of the most significant textile dye inventions in the 20th century. Indanthrene blue was the first anthraquinone vat dye, synthesized by René Bohn at BASF in Germany in 1901. He used the synthetic indigo reaction conditions with 2-aminoanthraquinone, fusing it with caustic potash, to obtain the colorant. By 1906, Bayer had introduced the first vat red and marketed a range of colors under the Algol brand. The United States imported vats from Germany because domestic production was hindered by German patent protection, the lack of sufficient anthracene (the source of anthraquinone), inadequate technical expertise of American chemists, and the large investment needed for organic solvent operations, specialized equipment, and explosion proof manufacturing buildings.
