Comparative Study Among Different Dyeing Methods of Polyester Fabric With Disperse Dyes

Authors: Elias Khalil

The objective of our project was to compare among different dyeing methods of polyester fabric with disperse dyes. At first the polyester fabrics (knit and woven) were dyed with disperse dyes. Three methods have been used for dyeing polyester fabrics (knit & woven): 1. Aqueous dyeing with a carrier (90°- 100°C) (batch dyeing) 2. High-temperature (120°- 140°C) aqueous dyeing (batch dyeing) 3. "Thermosol" dyeing (180°- 220°C) (continuous dyeing) After dyeing the dyed sample were subjected to several tests- 1. Color fastness to perspiration. 2. Color fastness to rubbing. 3. Color fastness to washing 4. Process effectiveness 5. Cost analysis 6. Tensile Stregnth test 7. Pilling Test Finally from the overall comparison for different processes , we found that High Temperature & High Pressure method is the most suitable dyeing method used in industrial production.
