Показать описание

Dyeing process of Cold Pad Batch (CPB). Process description: Total volume of pad-trough 10/15litres per metre of width of fabric (example 2 metres; volume 20 to 30 litres) 1. Immersion time 1.5sec 2. Bath temperature 25-30˚C 3. Pick up 70-80% 4. Fabric speed such as the time to completely renew the trough should not exceed 10 minutes Advantages of cold pad batch dyeing: a. Simplicity in process of dyestuff application b. Reduction in water consumption by 50 to 80% c. Reduction in energy consumption by up to 60% d. Reduction in chemical costs, other than dyestuff, by up to 50% due to elimination of salt and reduction of alkali requirements e. Reduction in labour costs by 40 to 60% f. Minimum fabric abrasion g. Excellent shade reproducibility from lot to lot h. So, we tried to give a brief idea on eco-friendly dyeing as
