を図るものである。This air-flow type dyeing machine mixes and supplies a dyeing liquid into an air stream that circulates and moves a rope-shaped object to be dyed in a processing tank, and jets a gas-liquid mixed fluid comprising the dyeing solution and the air stream onto the object to be dyed. Then, by performing the dyeing while circulating and moving in the treatment tank, an extremely low bath ratio is realized, and
It is intended to reduce the dyeing time by relaxing without tension.

処理槽に供給される洗浄液は１１０℃程度となる。In the air-flow type dyeing machine, a dyeing solution is supplied into a processing tank, and after the dyeing of the material to be dyed, the dyeing effluent is recovered from the processing tank at a high temperature and a high pressure in the circulation path. A heat exchanger for exchanging heat between the dyeing waste liquid and the cleaning liquid supplied to the processing tank is provided. For example, when the material to be dyed is polyester (PET), the dyeing effluent collected from the processing tank is about 130 ° C., whereas the cleaning liquid supplied to the processing tank by heat exchange is about 110 ° C.

色排液の回収と洗浄液の供給とを同時に行っていた。By the way, in the above-mentioned conventional dyeing machine, when the dyeing of the material to be dyed is completed, the high-temperature dyeing effluent stored at the bottom of the processing tank is recovered. While exchanging heat between the liquid and the cleaning liquid at normal temperature by a heat exchanger, the high-temperature cleaning liquid generated by the heat exchange is supplied into the processing tank. In other words, while collecting the dyeing effluent in the processing tank, the high-temperature washing liquid heat-exchanged with the dyeing effluent is supplied into the processing tank, and the collection of the dyeing effluent and the supply of the cleaning liquid are simultaneously performed.

に供給するようにした。According to the present invention, a high-pressure storage for storing a high-temperature cleaning liquid generated by heat exchange with a high-temperature dyeing effluent recovered from the processing tank in a cleaning liquid supply path between the processing tank and the heat exchanger. A tank is provided, and after dyeing the object, after collecting the entire amount of the high-temperature dyeing effluent from the processing tank, heat exchange is performed between the high-temperature dyeing effluent and the cleaning solution, and the high-temperature generated by the heat exchange. The washing liquid is temporarily stored in a high-pressure storage tank and supplied to the processing tank, or the high-temperature dyeing waste liquid collected in its entirety from the processing tank is stored in the dyeing drain collection path between the processing tank and the heat exchanger. Providing a high-pressure storage tank, after dyeing the material to be dyed, after collecting the entire high-temperature dyeing effluent from the processing tank and temporarily storing it in the high-pressure storage tank, heat exchange between the high-temperature dyeing effluent and the washing liquid, The high-temperature cleaning solution generated by the heat exchange is supplied to the processing tank. .

時間の短縮化や洗浄回数の低減化を図ることができる。As a result, the entire amount of the dyeing effluent is recovered while maintaining the high temperature state, so that all impurities such as oligomers and non-dyeing dyes dissolved in the dyeing effluent are discharged out of the treatment tank. Thus, it is possible to prevent impurities such as oligomers and non-dyeing dyes from adhering to the inner wall of the processing tank and the object to be dyed, thereby improving maintenance. In addition, since a cleaning liquid that maintains a constant high temperature state can always be supplied to the processing tank, the cleaning effect can be significantly improved, and the cleaning time and the number of times of cleaning can be reduced. it can.
