Dyeing of polyester/cotton with disperse/vat. In this process dyeing is carried out with padding process. After padding (dyeing) thermo fixation are apply on materials. then again padding then dry.
Dyeing of polyester/cotton with disperse/vat.
Padding is carried out with the help of following recipes;
• Disperse dye – X%
• vat dye – Y%
• 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.
Soaping – 2 gpl soap solution at 80°C
Hot wash and Cold wash
