text: A variety of fabrics such as wool, silk, nylon, polyester, polyacrylic, polyacetate, and polyurethane may be dyed with Glycoazodyes under moderate temperatures and pressures in aqueous solutions. First-generation Glycoazodyes dye cotton poorly. However, second-generation Glycoazodyes dye cotton effectively.  Wool dyed with Glycoazodyes shows good fastness when exposed to the ISO 105-C06 washing and ISO 105 X12 rubbing tests. 
  Glycoazodyes vary in their water solubility. They may be soluble in cold to warm water and may dissolve after stirring or upon addition. 
  Minor variations in absorption spectra occur when Glycoazodye solutions are prepared, using water, acetone, or methanol solvents. Converting a parent azo dye to a Glycoazodye may produce a small hypsochromic shift in the absorption spectra.
