'VS' BRAND DYES are Reactive Dyes possessing Vinyl sulphone as the
      reactive group. In presence of alkali, these dyes chemically react with
      the hydroxyl group of cellulose and form firm, convalent linkages. These
      dyes are versatile enough to suit different dyeing methods. Results are
      excellent and shades come clean and brilliant with no variation in dyeing
      as well as in printing.</p>

      dyestuffs posses poor affinity for cellulosic fibers in absence of salt
      and alkalis. For this reasons, they are suitable for use on pad. Their
      substantivity can be increased by addition of giauber's salt or common
      salt and alkali, making the dyestuff suitable on all conventional dyeing
      machine for loose material, yarn in hanks and packages and piece goods.
      The dyeing methods may therefore, be classified under the padding and
      exhaust processes, standing baths are not recommended, as in alkaline
      medium inactivation of the dyestuffs by reaction with water takes place as
      a side reaction.</p>
