| Abstract: | The dye-resist effect of reactive dye-resist agents in acid dyeing of silk was investigated. The dye-resist agent containing
dichlorotriazine achieved a higher resist effectiveness than others since they make a charge barrier against diffusion in
the silk fiber periphery due to the high reactivity of dichlorotriazine group. Especially, the increase in the number of ionic
groups in acid dyes leads to better electrostatic repulsion of reactive dye resist agent treated silk and thus improves the
resist effectiveness. However, the hydrophobicity effect of acid dyes on the dye-resist properties was relatively minor. |
