Use of Fine-bubbles in Dyeing and Finishing

Abstract

Fine bubble and ozone fine-bubble were used for textile dyeing process. Dyeing of woolen fabric using fine-bubble water showed shortening of dyeing time and darkening, though slightly. In the scouring of woolen fabric, ozone fine bubble water was used to lower the treatment temperature and shorten the processing time. In cotton fabric, ozone fine-bubble water can be used for bleaching. Ozone gas is easy to dissolve in low-temperature water, but maintaining the pH at 5 even at room temperature and adding the electrolyte component at about 0.03 mol / L makes it possible to obtain the same degree of whiteness as that of conventional method. Bleaching with ozone fine-bubbles does not require heating the treated water. In addition, the amount of chemicals to be used can be greatly reduced. The use of ozone fine-bubble technique can be said to be an environmentally friendly treatment method.
