ABSTRACT:
The present invention provides an apparatus suitable for decolorizing a textile product using ozone. The apparatus of the present invention enables the decolorization rate to be adjusted by adjusting the water content of the textile product and controlling the ozone concentration to achieve uniform decolorization. The decolorization apparatus for a textile product of the present invention includes an airtight container, a rotary drum which rotates in the airtight container, an ozone generator connected with the airtight container through an automatic valve, a water supply unit, and a blower unit which includes an air heater and supplies hot air and cool air to the airtight container. The ozone concentration inside the airtight container is maintained at a desired level by measuring the ozone concentration using an ozone analyzer and controlling the ozone generator.
