Note
  1. Please note that efficiency of desizing would depend upon type and quantity of size used, temperature, pH, treatment time as well as quality of water.
  2. For desizing of yarn dyed shirting, first ensure the fastness of yarn dyed fabric at 60 deg C.
  3. For better performance, use nonionic wetting agent.
  4. Solution of Desize-770 should be prepared in water of pH 6-7 only.
