Decolorization processed device and decolorization process method of fiber product

摘要

Although decolorization processing of the fiber product is done making use of ozone the ideal device is offered. In the device of this invention, adjustment of moisture content of the fiber product and adjustment of the decolorization ratio which is due to the control of ozone density being possible, uniform decolorization is possible.The decolorization processed device of the fiber product of this invention, chest the drum through 2 which turns inside 1 and this chest and automatic valve 42, the ozonator 41 which is connected to chest 1 and cooling water supply system has with the ventilation device 34 which has the air heater 31 which supplies the hot blast and the cold air inside 58 and chest 1. It measures the ozone density inside the chest, with ozone densitometer, 43 by the fact that ozonator 41 is controlled it keeps in desire density.
