Abstract

To prevent the discoloration of patterns, and the yellowing of silk, etc., from generating by a method wherein a specified amount, being set in advance, of a reducing agent is added to tap water of a washing liquid, and free chlorine is removed by oxidation reduction. A reducing agent 14 is placed in a housing case 15, and a water supply valve 21 is opened under a state wherein a lid part 16 is closed. By doing so, water is spread on the top of the reducing agent 14 from a water supply port 19 through a water supply passage 20. This water supply dissolves the reducing agent 14, and the water is poured in a washing tank working as a dehydration tank as well, through a water discharging port 22. By this motion, a specified amount being set in advance, e.g., approx. 1-3ppm of the reducing agent is spread in the tap water. As the reducing agent 14, calcium sulfite can be used. The fine particles of calcium sulfite being spread and emitted, oxidation-reduction-react with free chlorine in the tap water, and the free chlorine is removed, and the tap water becomes harmless. Therefore, discoloration, etc., can be prevented from generating.
