Definitions

  • This invention relates to a machine for scouring fabrics in open width, in particular for delicate fabrics.
  • scouring means both the washing and rinsing of fabrics.
  • the folds are sometimes so close to each other as not to allow very efficient scouring of the fabric.
  • An object of the present invention is therefore to provide a machine for scouring (to also include chemical treatment, such as the treatment of cotton fabrics with caustic soda) of fabrics in open width, in particular for delicate fabrics, in which the aforesaid drawbacks of the machines of the state of the art are not present.
  • a particular object of the invention is to provide a machine for the scouring and chemical treatment of fabrics in open width in which the folds undergo continuous modification during the course of the treatment.
  • a machine for the continuous or batch scouring of fabrics in open width, in particular of delicate fabrics comprising a treatment tank in which a treatment liquid is present, characterised by comprising a succession of sheets or cascades of liquid which strike the underlying folded fabric during treatment, so modifying the fold arrangement.
  • a sheet of liquid strikes the fabric before its immersion into the treatment tank, said fabric being conveyed into the liquid by a chute of liquid which slides along an inclined wall of the tank.
  • the continuous or batch scouring machine comprises a treatment tank 1 in which a liquid such as a conventional scouring liquid 2 is present, said tank being supported by a support 3 and comprising a base 1A.
  • the fabric 4 to be scoured and which is folded into folds during the scouring, which takes place in the tank 1, is struck by sheets or cascades of watery liquid 5A, B, C, D originating from overflow tanks 6 positioned above the treatment tank 1, said fabric 4 being introduced into the tank 1 by a chute of liquid 7 running along an inclined wall or chute 8 of said tank.
  • the machine of the invention comprises at least one liquid recirculation pump 9 positioned to the side of the tank 1, and from which a delivery pipe 10 extends to branch into a first and second pipe 11 and 12.
  • the first pipe 11 terminates in a overflow tank 13, which has a length (perpendicular to the plane of the drawing) equal to or greater than the height of the fabric, and is located at the upper end of the wall 8 of the treatment tank 1.
  • the second pipe 12 extends to position its end portion 14 above said treatment tank.
  • the liquid to form the chute 7 falls from the overflow tank 13, whereas vertical channels 15 branch from the portion 14 to terminate in the overflow tanks 6, from which the sheets of liquid 5 fall, their length (perpendicular to the plane of the drawing) being equal to or greater than the height of the fabric.
  • baffles 13A and 6A are positioned respectively in said tanks, in proximity to the discharge from which the liquid overflows.
  • the overflow tanks 13 and 6 are closed in the regions in which they are connected to the pipe 11 and channels 15 respectively, whereas they are obviously open in the discharge regions from which the liquid overflows to fall into the tank 1.
  • the fabric 4 is extracted from the tank 1 by known means (such as a tractor roller 30) and fed to other working stations. Alternatively, the fabric can be returned to the tank 1 for further scouring.
  • the sheets or cascades of liquid 5A, B, C, D and the chute 7 are fed by the pump 9.
  • This pump (which is advantageously and preferably paired with an analogous pump positioned on the other side of the tank 1 and connected to pipes analogous to those connected to the pump 9 and terminating in the overflow tank 13 and pipe 12) draws via the pipe 24 the scouring liquid which has reached the chamber 22 from the tank 1, and feeds it through the pipe 10 and then through the pipes 11 and 12 to the tanks 13 and 6. Finally, the water emerges from these tanks to form said sheets 5A, B, C, D and chute 7.
  • nozzles in elongated slot form can be provided in the base 1A of the tank 1 to feed the treatment liquid under pressure towards the fabric 4 present in the scouring solution, in order to disturb the fold arrangement.
  • the pump or pumps 9 are of variable throughput in order to be able to feed a number of liquid sheets or cascades 5A, B, C, D which varies according to the length of the treatment tank 1, and to feed these liquid sheets with a variable quantity of fluid depending on the fabric (light or heavy).
  • a machine constructed in accordance with the present invention enables the position of the folds in the fabric to be varied during the time in which it is undergoing treatment in the tank 1, so preventing permanent deformations, which could damage the fabric, arising at said folds.
  • the invention includes an embodiment wherein the fabric 4 forms an annulus by sewing its end parts and the fabric is repeatedly treated in the same tank by being guided by return cylinders 50, 51 which can be actuated so to impart movement to the fabric.
