In order to subject the used washing water to the regenerating treatment, it is preferable to regenerate the used washing water for each step such as a washing step after the steps of weight reduction, dyeing, printing and the like. It is better to regenerate each time and reuse the same process or the same device. This makes it possible to limit the types of substances to be separated, to clarify what kind of regeneration processing operation should be performed, and to enable efficient regeneration operation.
In particular, it is preferable to use a combination of regeneration treatments such as an ion adsorption method, an oxidation treatment method, a neutralization treatment, an activated carbon treatment, and a filtration treatment since there is an advantage that a huge facility is not required. Specifically, an ion adsorption method using an ion exchange resin, a neutralization treatment using an acid or an alkali, an adsorption treatment using activated carbon or the like, a microfiltration, an ultrafiltration membrane, a filtration treatment using a reverse osmosis membrane, or the like can be employed.

The absorbance obtained by the above-mentioned regeneration treatment is 0.01 or less, the electric conductivity is 20 μS / cm or less,
In the present invention, treated water having an evaporation residue of 100 mg / l or less is referred to as regenerated washing water. When the absorbance exceeds 0.01, there is a problem that the foreign matter in the washing water contaminates the object to be dyed, and the washing effect of the present invention is lost. In addition, the electric conductivity is 2
If it exceeds 0 μS / cm, the oligomers and undyed dyes on the fibers that are originally discharged into the wash water will not be discharged into the wash water but will reattach to the fibers. Even when the ratio exceeds / l, problems such as contamination of foreign matter in the washing water on the dyed substance occur, and the cleaning effect of the present invention is lost.

In the case where regenerated washing water is used in the dyeing and finishing step, if any one of the absorbance, electric conductivity and evaporation residue is not satisfied, the improvement of the color fastness which is the effect of the present invention cannot be achieved. That is, by setting the quality of the reclaimed washing water within the range of the present invention, the removability of foreign matters from fibers and the prevention of re-adhesion are superior to the case where ordinary industrial water is used, and as a result, an excellent washing effect is exhibited. It is presumed that. Preferably, the higher the purity, the better.

By using the regenerated washing water, prevention of uneven dyeing, prevention of uneven shading, removal of oligomers, and improvement of fastness to friction can be achieved as compared with ordinary industrial water. Conventionally, special processing was required to prevent these drawbacks, or means such as repeated washing multiple times, use of high-concentration cleaning agents, and washing at high temperatures were required. It was found that the solution could be solved all at once by using water.
