  • Such a method of operation is applied to each dyeing operation and each dyeing bath. Needless to say, it is necessary for the time required for feeding the specified quantity of a certain treating liquid into one dyeing bath to be shorter from the start of the operation to the start of the same operation of the next dyeing bath.
  • the feeding quantity of each treating liquid can always be constantly maintained by operating a constant quantity pump having a constant flow rate such as a diaphragm pump or plunger pump.
  • the liquid feeding period and its starting stage are preset for each dyeing bath, the specified quantity of the treating liquid can be charged independently to each dyeing bath. Also, if the time for charging the treating liquid is set at zero in the dyeing proof auxiliary liquid in the same time for every bath.
  • This method has been conventionally used in the past because there is little possibility of making mistakes in the operations and supervision is easy. However, this method had the following defects,
  • a preparation time t is required before the first treating operation and a preparation time t is required after the treating operation of time -t, has been completed and before the second treating operation is started.
  • a specified time lag is provided between the starting stages of the operation of the dyeing baths in order to remove the aforementioned defects. That is, time t from the starting of operation of dyeing bath B1 to the starting of dyeing bath B2 is used for preparation for dyeing of dyeing bath B2.
  • time t from the starting of operation of dyeing bath B1 to the starting of dyeing bath B2 is used for preparation for dyeing of dyeing bath B2.
  • feeding of dye is carried out at a dye feeding stage of each dyeing bath lagged successively in the same manner as the aforementioned charging of treating solution and consequently, in case of feeding dye to dyeing bath 1 in FIG. 3, for example, dye required for the substance to be dyed in dyeing bath 1 is charged into dye solution vessel 5 and dissolved into suitable hot water, next, this is fed to dyeing bath 1 by way of conduit 11, dye solution feed pump 6, liquid transfer conduit 12, dye solution feed valve 7 and solution transfer conduit 13,

  • the feature of the method of this invention is that the treating operation of a plurality of treating baths contained in a textile material treating apparatus is carried out in accordance with a treating program provided with a specified time lag, and for this purpose, a treating liquid vessel which contains the treating agent necessary for the treating operation and connected fluidly to all treating baths is disposed for each treating agent.
  • One treating liquid vessel in the treating apparatus is sometimes used successively for different treating liquids and of different concentrations such as in the case of a dye vessel.
  • One of the problems in such a case is that, after the treating liquid contained in the treating liquid vessel has been fed to the treating bath, this treating liquid vessel and the transferring passage must be rinsed thoroughly before the next treating liquid is filled in it.
  • Another problem is that the treating liquid will remain in the treating liquid vessel and the transfer passage, and consequently, the amount of treating agent to be fed will be insufficient to the extent of this remaining quantity.
  • the operation of feeding the treating liquid in the treating liquid vessel into the treating bath is carried out, then this treating liquid vessel and the transfer passage are rinsed with a specified quantity of rinsing water and the operation of feeding this rinsing water is carried out after rinsing of the treating bath has been completed.

  • a fixed quantity of hot or cold water is fed from hot or cold water source 45 by way of an ejection pipe 46 provided with a spray nozzle up to the upper limit of level meter 48, stirrer 47 is started, hot or cold water feed from 45 and 46 stopped, dye is charged into this dye solution vessel 49 and dissolved with stirring for a fixed time.
  • the dye solution is sent by dye solution feed pump 50 through conduit 55 liquid transfer conduit 56, and in case the dye solution is to be fed to dyeing bath A, this is carried out through liquid feed conduit 53 by way of dye solution feed valve 51.
  • the rinsing water ejected on the wall surface of the dye solution vessel flows down this wall surface while rinsing it and is discharged from the discharge outlet at the bottom of the vessel but when the rinsing water remains at the bottom of the vessel, foam and suspended substances float up to the surface of this residual liquid and this suspended substance remains after the rinsing water has been discharged. Therefore, it is necessary for the rinsing water fed to the dye solution vessel to be discharged immediately and not allowed to remain at the vessel bottom. In other words, the feed flow rate of the rinsing water and the discharge fiow rate must be equal. For this purpose, the relation of R g S must exist between the flow rate of rinsing water R and the discharge capacity of the discharge pump 5.
  • the relation of Q,-, Q RT must exist between the volume of dye solution fed initially Q, and the volume of rinsing water fed after this RT.
  • the internal wall surface of the dye solution vessel 49, pump 50, feed valve SI and the liquid transfer conduits 55, 56 and 53 are rinsed completely by this discharge and rinsing method and it will become possible to feed a second dye solution of a different color tone to a different dyeing bath by using the same dye solution vessel 49, pump 50 and the liquid transfer conduits.
  • valve 51 is operated, the dye solution is passed through conduit 57 from conduit 46 and the passage through conduit 53 is closed. Also, valve 52 is operated to permit the dye solution to pass through conduit 54 from conduit 57 and the passage to conduit 58 is closed.

  • the apparatus further comprises a steam control valve 68 for controlling temperature of the dyeing bath, a pressure reducing valve 69 for steam, a cooling water control valve 70 for temperature control, a pressure reducing valve 71 for the cooling water.
  • the temperature is controlled by a suitable program control means in accordance with the specified program such as that indicated in FIG. 1. Also, the operation of the apparatus is carried out by a suitable program operation means at an operation stage specified in the program. The temperature control of this apparatus is carried out by operating a steam control valve 68, cooling water control valve 70, heat exchanger 65, steam trap 66 and cooling water discharge valve 72 by using the program control means. Also, the operation of this apparatus is carried out in the same manner as described in the explanation of FIG. 4.
  • auxiliary treating liquids such as the addition of sulfuric acid solution in the dyeing process of wool fiber products by acid dye and addition of caustic soda and sodium hydrosulfite in the dyeing process of cellulose fiber products by fine dispersed vat dye must be carried out very slowly over a long period of time.
  • the treating operations of the various treating baths are carried out in accordance with an operation program prepared with a mutual specified time lag but frequently, the time required for feeding the aforementioned treating liquids to the treating bath becomes longer than the interval of the operation time for each treating bath fixed in the program.
  • an operation program prepared with a mutual specified time lag but frequently, the time required for feeding the aforementioned treating liquids to the treating bath becomes longer than the interval of the operation time for each treating bath fixed in the program.
  • this improvement is attained by carrying out simultaneously the distribution operation of sending successively to the auxiliary vessels for auxiliary treating liquid provided for its treating bath the specified quantity of the auxiliary treating liquid at a specified stage in accordance with the specified operation program and the feeding operation of natural dropping to this treating bath at a flow rate lower than the flow rate in the distribution.
  • the latter was unsuitable for a dyeing apparatus composed of a large number of batch-type dyeing baths, because a large number of feed pumps corresponding to the product of the number of the kinds of auxiliary agents and the number of dyeing baths were required for the apparatus.
  • the equipment cost is reduced and manual dye dissolution work or rinsing of the dye solution vessel is unnecessary, personnel for feeding the auxiliary treating liquids to the dyeing bath can be omitted, concentration of labor for charging and discharging the material into and from the dyeing bath can be ignored by introducing time lag into the operation program of the various treating baths and concentration of feeding quantity of water and steam can be reduced, by which it will become possible to carry out efficient treatment operation automatically and easily by skillful application to the batch-type dyeing condition.

If D is constant, Q becomes larger the higher the liquid level I-i becomes and smaller the lower the liquid level I-I becomes. Therefore, it is necessary only to make H small when it is required to make Q small but on the other hand, the variation of 0., during the feeding operation becomes large so that the aforementioned requirement of feeding the auxiliary treating liquid at as constant a pressure as possible cannot be satisfied. In order to fullfil such a requirement and make a decrease of the final flow rate of the auxiliary treating liquid from the initial flow rate below 15 percent, it is necessary to satisfy the following relationship.

If the length of the fine dropping pipe is made too long, the resistance against flow of the auxiliary treating liquid through the fine dropping pipe becomes larger and the flow rate thereof becomes lower. The optimum length of the fine dropping pipe is determined by the kind of liquid and diameter of the fine dropping pipe.
