About Ozone Bleach
Issues of current scouring and bleaching processes.
In the manufacture of textile products, the dyeing process requires the most energy consumption. Dissecting the process still further, the bleaching portion wastes the most energy.
All kinds of textiles, whether at the yarn or fabric stage of processing, must undergo the scouring and bleaching processes before piece bleaching or dyeing. It is said that bleaching is the most fundamental process of all textile manufacturing.
Modern bleaching processes require high-temperature water at roughly 120 °C over a duration of 40-60 minutes, and utilize a large volume of chemicals. For the past 50 years, this technique has not evolved: it can hardly be called “environmentally friendly”.
