Operation Parameters of UV Photografting of Modified Reactive Dye with 2-Methyl-3-Buten-2-Ol onto Cotton Fabric

Abstract:

The clean dyeing of cotton fabric was realized using UV-induced photografting of modified reactive dye. The reactive dye was interacted with 2-methyl-3-buten-2-ol to introduce C=C double bonds. The modification conditions of reactive dye were discussed. The dyed cotton fabric was measured by color difference, scanning electron microscope(SEM),and attenuate total reflection Fourier Transform infrared(ATR-FTIR). Under the conditions of pH value of 8, C.I. reactive red dye 198/2-methyl-3-buten-2-ol mole ratio of about 1:3, interaction time of 40 min, interaction temperature of 70°C, and dye concentration of 40g/L,good color depth of cotton fabric was achieved. The results of SEM and ATR-FTIR verified the occurrence of graft polymerization.
