Effect of a mixed fine bubble liquids in the dyeing process

Abstract

High environmental load was reported in the dyeing process. In this study, we focused on effect of fine bubble (microbubble and ultra-fine bubble) mixtures in the dyeing process. Dyeing experiments on the silk, cotton, and synthetic fibers were conducted. High dyeing rate on the synthetic fiber by using both microbubble and ultra-fine bubble was obtained. However, the dyeing rate on the silk or cotton by using microbubble was reduced. Moreover, relationship between the electrical double layer and the test liquids was discussed.
