Machinery Use for this Process: - Generally, Mercerizing machine is use for organdie finishing. Stenter machine also use for this finishing.But it's important that,those machine materials can not react with Sulphuric acid.So ,this process done by very carefully.

Process Procedure:

At room temperature ,fabric pass into the 110 degree concentration of sulfuric acid in 4-5 second. After 4-5 second the fabric wash by cold water to remove acid from fabric and neutralized by Alkali. Sometimes Pyridine or Glycerine can be used with sulfuric to less it's rapidly action.By control process ,formaldehyde also used with sulfuric acid. Nitric acid and phosphoric acid also use for this finishing process. At 106 degree concentration of phosphoric acid ,organdie finishing also give on Rayon fabric.
