• Anionic wetting agent – 2 gpl

• Antimigratin agent – 10 gpl

• PH – 5.5

Dry the padded materials (fabric) at 110°C for 6 sec.

After padding, thermo fixation is carried out at 190°C for 60 second.

Then, pad the blend materials (fabric) through

• NaOH – 110-125 gpl

• Na2S2O4 – 30 gpl

• wetting agent – 1 gpl

• Dispersing agent – 2 gpl

Steam the sample at 100°C for 50 second.

Oxidation with 3 gpl , H2O2 (35%) at PH – 8 – 9 at 50°C.
