发明名称 METHOD OF CONTINUOUS CHANGING DYE-COLOUR IN SPRAY DYEING
摘要 Method of Continuous Changing Dye-colour in Spray Dyeing A method of continuous changing dye-colour in spray dyeing for a long tape, which is fed by guides continuously. According to a preferred embodiment, one dye-solution is sprayed for the tape from at least one dyeing-nozzle connected to one feeding line, which is either of a pair of feeding lines and which feeds selectively the one dye-solution or one cleaning-solution. When the tape is fed with a predetermined length, the spraying of the one dye-solution is stopped. Then, the one dyeing-nozzle is exchanged with at least one other dyeing-nozzle by turning the one dyeingnozzle away from the tape and turning the other dyeing-nozzle to the tape for spraying another dye-solution. While the other dyesolution is sprayed, the one dyeing-nozzle, which was used for spraying for a proceeding sprayed portion of the tape, and the one feeding line, to which the one dyeing-nozzle is connected, are cleaned with the one cleaning-solution to prepare for spraying a new dye-solution Further, at just on time when an undyed portion, which is produced by the exchanging of the dyeing-nozzles, passes through each guide, the dye-solution attached to each guide is removed so as not to mix into a following sprayed portion of the tape.
