TEXTILE PRODUCT DECOLORING DEVICE AND DECOLORING METHOD

摘要

A device suitable for decoloring textile products by using ozone. With this device, adjustment of water content of textile products and adjustment of decolorization rate by control of ozone concentration are possible, and uniform decolorization is possible. A textile product decolorizing device comprises a closed vessel (1), a drum (2) rotating in this closed vessel, an ozonizer (41) connected to the closed vessel (1) through an automatic valve (42), a water supply device (58), and a blower (34) equipped with an air heater (31) for feeding hot air and cold air into the closed vessel (1). The ozone concentration in the closed vessel is measure with an ozone concentration meter (43) and the ozonizer (41) is controlled, thereby retaining a desired concentration.
