The Dyeing Performance Research Of Lightmax Fiber

Lightmax fiber is a kind of regenerated fiber,which uses natural kenaf or jute as the raw material.Lightmax fiber was obtained by using unique production techniques. Lightmax fiber with high wet modulus could improve the crease resistance of the fabrics.It’s excellent antibacterial property could help us inhibit Staphylococcus aureus and many other bacteria.So Lightmax fiber was called“Green health care function fiber”. It was well known that the morphology and supramolecular structure of the fibers were different, so the dyeing properties of different fibers were various.Lightmax fiber and viscose fiber were dyed by Reactive Red B-2BF, Reactive Yellow B-4RFN and Reactive Blue B-2GLN at the temperature of 50℃,60℃ and 70℃. The thermodynamics and kinetics of the two fibers were discussed and compared.Finally, there was a simple exploration about the optimum dyeing process of Lightmax.Through a large number of experimental data,the dyeing properties of Lightmax fiber was not as well as the ordinary viscose fiber.On the dynamic aspect,the dyeing percentage,diffusion coefficient and half dyeing time were not better than that of viscose fiber.On the thermodynamics aspect,the dyeing affinity of and the amount of dye on the fiber also could not catch up that of viscose fiber.Finally,the optimum technological condition was determined as follows,Reactive Red B-2BF:the temperature was at 60℃,the dosage of salt was 60g/L,the dosage of soda ash was 20 g/L;Reactive Yellow B-4RFN:the temperature was at 70℃,the dosage of salt was 50g/L,the dosage of soda ash was 20g/L;Reactive Blue B-2GLN:the temperature was at 75℃,the dosage of salt was 40g/L,the dosage of soda ash was 30g/L.
