Definitions

  • the present invention relates to a method for the treatment of textiles and like materials, materials consisting of or containing synthetic fibers, in bulk or in worked condition, during which treatment which may be washing, bleaching, dyeing or the like, liquid and gas, preferably in a closed circuit, is pressed through the material.
  • textile as used throughout this disclosure is meant to means synthetic as well as natural fibers.
  • the problem which is to be solved by the present invention consists in proposing a method for avoiding this undesired influence on the material.
  • the method also will not detrimentally influence other necessary measures performed during the treatment, for instance the shrinking of the textile material in such a manner that this will obtain the desired voluminous character.
  • the present invention proposes a method of solving this problem and is essentially characterized by the treating liquid being continuously supplied with small amount of gas in a finely divided state in such a manner that the very small bubbles generated will penetrate the material thereby separating the filaments thereof.
  • the apparatus includes a container 1 generally termed an autoclave, which at one end is provided with a removable lid or cover 2.
  • a perforated cylinder 3 is mounted within container and a material 4 to be treated is wound on the cylinder.
  • the cylinder 3 is only supported at its end in such a manner that an annular space remains between the material and the inner wall of the container 1.
  • the end of the cylinder 3 remote from the lid 2 is sealingly affixed to an inlet 5 which is connected by a conduit 6 to a pump 7 having a comparatively high capacity.
  • the perforations of cylinder 3 are so designed that the perforated part will be completely covered by the material.
  • a return conduit 8 is connected to the lower part of the container 1 and passes through a heat exchanger 9 located between the container and the pump.
  • a nozzle 10 is arranged in the feed conduit 6 from the pump 7 and a compressed air conduit 11 is connected to the nozzle.
  • the conduit 11 is provided with a manometer 12 and a reducing valve 13, and is connected to a suitable source of supply (not shown).
  • the nozzle 10 has a very small outlet opening, and will impart a very high velocity to the air (up to -400 meters/sec) It distributes the air, for example in the form of a cone.
  • the reducing valve 13 will maintain a pressure in the conduit 1 1 of l-5 atmospheres above the static pressure in the autoclave l.
  • the capacity of the pump 7 is such that the volume enclosed in the autoclave 1 will be exchanged l.52 times per minute.
  • a quantity of very finely subdivided air is continuously added (the quantity of air will amount to about 01-10 liters per minute at 20 C. and 760 mm. Hg for a pump quantity of 10,000 liters per minute).
  • the air introduced into the stream of liquid will be further subdivided and mixed therewith due to the turbulence, and the chemical compounds in the treating liquid will impart an emulsifying effect.
  • the air has higher pressure that the liquid and furthermore, due to the difference in temperature between the air and liquid an expansion of the air will occur, which further subdivides the air bubbles.
  • the very small air bubbles will penetrate the different layers of material and separate the filaments thereof. The liquid will thus uniformly act upon the material.
  • a compression of the material is avoided and a possible shrinking may occur to a desired extent.
  • the liquid must be steadily supplied with new air.
  • the air is collected in the upper part of the container, above the liquid surface and is evacuated in any suitable manner.
  • This evacuation is effected by means of a conduit 14 which is connected to the upper part of the autoclave and is connected via branch conduit 15 to a glass tube 16 acting as a level indicator.
  • This tube is, by way of a valve 17 and conduit 18, in communication with the return conduit 8 to the pump 7.
  • the evacuation conduit is furthermore connected to an expansion vessel 19 from which a conduit 20, by way of a cooler 21 and a valve 22 is connected to the upper part of an open receptacle 23.
  • the valve 17 is only open sufficiently to bring about a subpressure in the conduit 18 and glass tube 16 due to an ejector action.
  • This static pressure in the autoclave is regulated by means of a valve 25 arranged in a conduit 26 between the receptacle 23 and lower part of the autoclave.
  • a further cooler 27 is included in the conduit
  • the dyeing liquid including all necessary chemicals was heated in a preparator to 75 C. Air in a finely divided state was supplied to the liquid during the whole dyeing operation.
  • the present method offers the following advantages:
  • the dyestutf absorption may be kept at normal value compared to previously known methods, if the flow Dyertul'l percentage Time Temperature in liquid min. liquid transferred from preparator to apparatus. injection of air beins 75' I00 2 minv heating of the apparatus 4 min. liquid trander completed 5 min. pressure maintaining pump 24) started 80' I0 min. 93' I3 min. 97' l5 min I00 70 I65 rain.

  • washing 85" 53 min. drawing ofthe liquid 57 min treatment finished velocity is decreased. This will diminish the pressure drop through the material, whereby the volume and the consistency of the material will be influenced. Especially with texturized or thermoplastic materials this will be of importance as such materials usually will flatten due to the liquid passing through the material.
  • c. By a suitable choice of the air bubbles and the quantity thereof it is possible to, when forcing the liquid from inside a cylinder outwards through the material wound thereon, to obtain an intermittent retarding action of the dyestufi. This means that the dyestuff, carried by air (already made) bubbles-flows along the fibers of the material intermittently. This retarding action is decreased as the size of the body of material increases.
  • the embodiment of the invention described above employs a horizontal autoclave or may be effected by atmospheric pressure with or without a rotating material support It is not essential, when employing the invention, to employ an autoclave, or to rotate the material support.
  • the invention may, with the same advantage, be utilized with horizontal as well as with vertical containers. These may or may not be subjected to a static pressure, and they may be designed in such a manner that material is still or will be kept in movement during the treatment.
  • the values indicated in the example cited above refer to a specific material will of course vary somewhat with other materials and dyestuff.
