Definitions

  • the present invention relates to a method of processing a cloth and a cloth processing apparatus which dyes, bleaches or scours cloth by means of cloth processing liquid circulation.
  • it especially relates to a method and apparatus in which a cloth processing liquid of a certain concentration is prepared through the dispersion and dissolution of cloth processing powder such as dyes, pigments and surfactants in a solvent by making effective use of a large fluid friction locally occurring in the cloth processing liquid circulation system of said apparatus as stirring force, and processing cloth successively with said cloth processing liquid flowing in said circulation system.
  • JP-A 7102466 discloses a method for the delivery of a powdery agent into a cloth processing apparatus which makes use of the fluid friction occurring in the system to dissolve said powdery agent.
  • the powdery agent is introduced in the region of the intake of the circulation pump of a cloth circulation system as this region naturally has a larger fluid friction than other regions of the cloth circulatory system.
  • GB A 1561988 discloses a process for the isothermal high temperature dyeing of hydrophobic fibres in a closed dyeing system using a water insoluble disperse dyestuff.
  • the fibres are retained in a dying container through which dying liquor is circulated.
  • the dyestuff is contained in a large capacity closed chamber and is dispersed by feeding bypass liquor into this chamber, via a baffle, to promote mixing in the closed chamber until the pressure in the chamber builds up sufficiently to open the non return valve so as to discharge the dispersed dyestuff via a nozzle into the liquor circulating through the dying container.
  • JP A 3715434 discloses a method for the dyeing of a cloth in which the dyestuff is introduced into a dissolution tank and gradually dissolved by feeding a portion of the circulating dyeing liquid into said tank from overhead. The dissolved dyestuff is then passed to the suction side of a circulatory pump.
  • the present invention provides both a means of efficiently preparing said liquid and of successively processing cloth as required with said liquid in the circulation system of said cloth processing apparatus. This overcomes the need for any special separate device for preparing said liquid, and also provides an apparatus used in the same method which is labor-economical as well as space-saving.
  • the present invention permits liquid quality control whereby not only cloth can be processed with a cloth processing liquid of an ideal concentration and without impurity due to the mixture of the residue of previously prepared processing liquids, but also liquid loss in the transfer can be greatly reduced in comparison with the prior art.
  • the present invention permits liquid quality control whereby cloth can be processed in a liquid of consistent quality because of the shorter elapse of time from its preparation until its actual use.
  • a cloth processing apparatus wherein the cloth processing liquid circulation system includes a dyeing sink which is connected with the stirring tank through a connection pipe so that in use the liquid levels in the sink and the tank, can be maintained the same.
  • a cloth processing apparatus wherein the auxiliary circulation system is provided with a separate pump to accelerate liquid flow in the auxiliary circulatory system.
  • the cloth processing liquid may be used to perform a required cloth treatment or processing such as, for example, dyeing, scouring, bleaching and caustic reduction with the aim of physically and chemically improving the appearance and quality of cloth.
  • the cloth processing circulatory system itself may be a conventionally well-known apparatus such as a jet dyeing machine, a beam dyeing machine, a jigger dyeing machine and a wince dyeing machine. All those dyeing machines can also perform a required processing on cloth by using the variety of cloth processing liquids (such as for scouring, bleaching and caustic reduction) besides dyeing.
  • the cloth processing powder can be either directly fed as such into the above-mentioned stirring tank contained in a water-soluble sack or a permeable basket which is introduced into the tank.
  • endless cloth (W) is subjected to dipping, dehydrating, rubbing, squeezing and loosening conditions in a cloth processing circulatory system so as to be uniformly bathed in a cloth processing liquid (D) in such a repetitious process that (i) it is dipped in said liquid (D) which has collected in a dyeing sink (2) provided at the bottom of a processing tank (1) while slowly and serpentinely moving and being partly submerged in and drifting on said liquid; (ii) then, the cloth is lifted by a pull-up reel (3) and directed towards an injection supply passage (5) through a reel box (4); and (iii) then, the cloth (W) within said passage (5) is carried over at high speed into an inflow opening (5a) of said dyeing sink (2) by the force of said liquid (D) injected from a jet nozzle (6) and is released from that force just when it has emerged from said passage (5) so as to be directed again towards said reel
  • the circulation system of said cloth processing liquid (D) by means of the cloth processing apparatus (T 2 ) of the present embodiment is constituted not only by the cloth processing circulatory system but also by an auxiliary circulation system for preparing said liquid (D).
  • cloth processing circulatory system also comprises an intake passage (8) connected to a liquid reserve portion (7) formed at the bottom of said dyeing sink (2), a circulation pump (9) the suction side of which is connected to said intake passage (8), a liquid supply passage (10) connected to an outlet of said circulation pump (9), a filter (11) connected to the end portion of said liquid supply passage (10), a multipipe heat exchanger (12) connected to an outlet of said filter (11), a heated liquid supply passage (13) connected to an outlet of said heat exchanger (12).
  • numeral (8a) indicates an electromagnetic valve provided on a branch passage of said intake passage (8) which is used for draining said liquid (D) from said apparatus (T 2 ) or polluted water generated when the internal circulation system of said apparatus (T 2 ) is cleansed.
  • auxiliary circulation system of said apparatus (T 2 ) in the present embodiment has a powder input and stir tank (17) which is connected to the bottom of said dyeing sink (2) through a connecting pipe (2a) and the liquid level of which is maintained at the same level as that of said dyeing sink (2).
  • a pipe (20) connects the bottom of said tank (17) with said liquid supply passage (10).
  • said tank (17) is provided with an airtight cover (17a) easy to open and close, and the inside of said tank (17) becomes airtight by closing said cover (17a).
  • the most characteristic feature of the apparatus (T 2 ) in the present embodiment is in that said powder input and stir tank (17) is included in said auxiliary circulation system wherein it is connected to the bottom of said dyeing sink (2) through said connecting pipe (2a) so that its liquid level is maintained at the same level as that of said dyeing sink (2).
  • the method of preparing said cloth processing liquid (D) by means of the cloth processing apparatus (T 2 ) of the present embodiment is explained as follows by taking a dyeing liquid as an example.
  • water is supplied as a solvent to the cloth processing circulatory system by opening an electromagnetic water supply valve (8b) provided on said intake passage (8).
  • an electromagnetic water supply valve (8b) provided on said intake passage (8).
  • the quantity of water as required is reserved in said dyeing sink (2) and likewise the same level of water as kept in said sink (2) is reserved in said powder input and stir tank (17) via said connecting pipe (2a).
  • said cover (17a) is closed after a water-soluble sack containing a certain quantity of a dyeing powder (P) is supplied into said tank (17), and then an electromagnetic valve (21) provided on said pipe (20) is opened.
  • the concentration of the dyeing liquid flowing in the whole circulation system of said apparatus (T 2 ) becomes uniform, and the dyeing treatment of the cloth (W) completes in a process where the cloth (W) repetitiously moves between said dyeing sink (2) and passage (5) in contact with said dyeing liquid (D).
  • This structure of the cloth processing apparatus (T 2 ) of the first embodiment is simple so that it can be manufactured inexpensively and is advantageous in saving equipment & plant cost.
  • Fig 2 of the drawings basically there is no difference between the present embodiment and the first one in the structure of the processing tank (1), the dyeing sink (2), the pull-up reel (3), the reel box (4), the injection supply passage (5), the jet nozzle (6), the liquid reserve portion (7), the intake passage (8), the circulation pump (9), the liquid supply passage (10), the filter (11), the multipipe heat exchanger (12) and the heated liquid supply passage (13) as well as in the cloth processing method.
  • the cloth processing apparatus (T 3 ) of the present embodiment differs from that (T 2 ) of the first embodiment.
  • the powder input and stir tank (17) in the auxiliary circulation mechanism of the apparatus (T 3 ) is also structured in the same manner as that of the apparatus of the first embodiment where it is connected to the bottom of a dyeing sink (2) through a connecting pipe (2a) so that its liquid level can be maintained at the same level of said dyeing sink (2), but the tank (17) of the present embodiment is characterised in that it is connected to a liquid reserve portion (7) formed at the bottom of said dyeing sink (2) through pipes (22a) and (22b) between which an auxiliary circulation pump (23) is interposed to accelerate liquid flow.
  • said auxiliary circulation pump (23) provided between said pipes (22a) and (22b) in the auxiliary circulation mechanism of the cloth processing apparatus (T 3 ) causes very large fluid friction inside said tank (17) so as to stir said powder (P) as well as to disperse and dissolve it more effectively.
  • the cloth processing apparatus embodied in the present invention, allows efficient preparation of a required cloth processing liquid. This is achieved simply by feeding a cloth processing powder into the circulation system of said apparatus. It therefore becomes unnecessary not only to separately install a powder dissolution tank or a liquid control apparatus in the factory, but also to do such preparatory work as carrying a cloth processing liquid prepared in said tank or apparatus over to the cloth processing apparatus for supply.
  • the cloth processing apparatus of the present invention does not require any extra space for a device to prepare a cloth processing liquid or for the carriage of a prepared liquid as was previously required.
  • the adoption of the cloth processing method and the apparatus embodied in the present invention allows the preparation of a cloth processing liquid of a required concentration, and the successive performance of cloth processing with said liquid.
  • the problems of contamination of the liquid due to the mixing with residues of the previously prepared liquids, the inconsistent concentration of the liquid depending on the person in charge of the preparation of the liquid, and qualitative changes of said liquid due to the long lapse of time from its preparation till its actual use, are also overcome.
  • the cloth processing apparatus embodied in the present invention is provided just with a powder input and stir tank in its circulation system, its structure becomes simplified and it can be manufactured inexpensively so that it is very economical to use from a labour stand point as well as being cost-saving.
  • the cloth processing apparatus embodied in the present invention can greatly contribute to the streamlining of the cloth processing factory so that its industrial applicability is extremely high.
