'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>
