Paper Title:
Application of Ionic Liquid in Silk Dyeing
  Abstract

In this paper ionic liquid 1-butyl-3-methylimidazolium chloride (BmimCl) as accelerating agent was applied in silk dyeing and the dyeing performances of silk with ionic liquid were determined under different dyeing conditions. The obtained results indicated that the rate of dye uptake was about 85.4%, the K/S value was 11.2, breaking strength was 426 when 2 g silk was immersed in 60 ml dye solution, the concentration of ionic liquid was 2.0%, dyeing temperature was 50 °C and bath ratio was 1:30. Investigation on dyeing mechanism of silk with ionic liquid indicated that ionic liquid BmimCl interacted with amino acid in surface of silk and dyes through the electrostatic interaction between cation Bmim+ and the CO2- group of amino acid and SO3- group of dye in dyeing process.
