Definitions

  • This invention features a novel method and associated apparatus for processing fragile goods such as knit materials and the like wherein the web of material is guided into face-to-face superimposed position over a belt that is coextensive with the web at least during the processing thereof and which trans ports the fabric in open width or flat tubular condition about rollers in a scouring stage or the like and thence into a drying stage where the material is heated to evaporate liquid carried from the scouring stage. Upon the completion of the drying operation, the belt and material are separated.
  • FIG. l is a sectional view in side elevation of an apparatus made according to the invention.
  • FIG. 2 is a view similar to FIG. l but showing a modification thereof.
  • FIG. 1 in particular there is illustrated an apparatus for processing on a continuous basis running fabric web 110, through solvent scouring operations and the like.
  • web shall include woven and nonwoven materials, knit goods and the like and which may be in a flat tubular or open-width condition.
  • the apparatus is particularly useful in the continuous dry cleaning of knit goods, for example, which are subject to lateral and longitudinal distortion when tensioned.
  • the apparatus is generally organized about a tank 12 the walls of which are closed except for entrance and exit slots 14 and 16 which may be provided with suitable seals.
  • the tank 12 is divided generally into a wet-out section ill on the left-hand side thereof its viewed in FIG. 1 and a drying section at the right-hand end.
  • the web It) may he guided from n supply roll 22 or directly from a prior process into face-to-face open width superimposed engagement with a continuous belt or apron 24 at least as wide as the web 10.
  • the apron 24 runs continuously in a closed loop from one end of the tank to the other and carries the web 10 substantially fully supported, without appreciable tension, through the apparatus.
  • the web is of a type such as knit material which is subject to lengthwise and widthwise distortion during processing, or if the material has a high stretch-strain ratio, such tension is to be avoided.
  • any such tension in the web is substantially eliminated by the use of the apron 24.
  • the apron is of a tough flexible material, such as fiber glass, wire, nylon or the like, which is inert to the liquid employed and fabricated so as not to stretch to any appreciable extent when longitudinally tensioned.
  • the belt may be porous or im perforate although a porous, openwork belt is preferred to allow better circulation of the solution through the web as well as to enhance heat transfer to the web.
  • a second apron 26 shown in dotted line in FIG. I, may be employed to sandwich the web It) as it is carried through the apparatus. The sandwiching arrangement is particularly useful where processing discontinuous webs.
  • the web 10 together with the apron 24 pass over guide rolls 28, 30 and 32 and are guided down through the slot opening 14 into the tank 12.
  • the superimposed web and apron then pass into a sump containing a quantity of liquid cleaning solvent, for example.
  • the bath of solvent is contained in the lower left-hand corner of the tank l2 in the sump defined by walls 341 and 36 as well as by the sidewalls of the tank.
  • the web and apron pass in and out of the bath by means of a series of rolls 38 and 410, etc., the lower rolls being submerged and the upper rolls preferably disposed above the surface of the liquid. During their passage through the solvent the surface tension of the liquid aids in maintaining the web and apron in close contact.
  • each submerged roll is arranged to substantially float in the liquid to reduce frictional bearing drag.
  • each roll is mounted in double bearings with one bearing of each double bearing being driven by means of a variable speed control mechanism so that the bearing drag is reduced substantially to zero.
  • a slight and positive forward urge is given to each roll while a slight upward and downward tension is given to the web by the zero weight submerged rolls.
  • the rolls 38 and 40 substantially eliminate bearing drag and at the same time produce no appreciable tension on the web or apron travelling over these rolls.
  • rotary impellers 44 are mounted in the tank below the liquid surface and between each course of travel of the web and apron as they pass in and out of the bath.
  • the impellers are employed to flush the solvent through the web to insure optimum interaction between the solvent and the web and are made in accordance with US. Pat. application, Ser. No. 815,329 filed Apr. 1 l, 1969 by Harold R. Wilcoxand entitled Continuous Open Width Washer".
  • the impellers 44 are comprised of central rolls or cores 46 driven by a simple drive system and each provided on its outer surface with spaced longitudinal abutments 43 such as rods or the like whereby the liquid will be pulsed against the open face of the fabric carried by the apron to enhance the liquid to fabric contact.
  • the impellers 416 are each of a length corresponding at least to the width of the web and arranged in groups on opposite sides of the web so that each section of the web will be subjected to the action of pairs of impellers.
  • the abutmcnts 418 are cylindrical in cross section or at least rounded on their outer portions to eliminate any chance of scoring or otherwise damaging the fabric should it come in contact with the impellers.
  • the web and apron After the web and apron have made a number of passes in and out of the solvent, they travel upwardly against an idler roller 50 and are subjected to a spray of solvent from a transverse nozzle 52 shielded by a baffle 54. Clean solvent is I delivered through the spray nozzle by means of a pump (not shown) from a solvent storage tank, typically located at the side of the main housing. In practice, the solvent in the storage tank is recovered by condensation, filtered or otherwise cleaned before reuse.
  • the web and apron travel over an idler roll 56 along a more or less horizontal path into the bite of a pair of nip rolls 58 and 60 which squeeze excess solvent from the web. Between the roll 56 and the nip rolls additional clean solvent is washed over the width of the web from an inclined puddling board 62 which receives clean condensate from a condenser 64 and directs the flow into the horizontal reach of the web to wash out any residual particles in the web. From the nip rolls the web and apron travel about a tensioning roller 66 which maintains sufficient longitudinal tension on the apron to insure proper driving contact between the apron and the various rolls at least one of which is driven.
  • a baffle 68 is disposed below the nip rolls to direct the liquid squeezed from the web back down into the sump tank for reuse.
  • a condenser 70 which drains onto an inclined channel 72 extending through the drying section of the tank and back into the sump.
  • the drying section of the tank includes a plurality of rotary heated cylinders or cans 74, all relatively large in diameter and typically heated by steam under a pressure on the order of 100 psi.
  • the cylinders 74 serve to heat the web sufficiently to cause any solvent entrained in the web to vaporize into the tank atmosphere.
  • the web can be held in close contact with the outer surfaces of the cylinders for optimum heat transfer and thereby make the most efficient use of the drying stage.
  • substantially all of the solvent will have been vaporized from the web and apron which then are moved over an idler roll 76 out through the exit slot 16 and over rolls 78 and 80.
  • the web is then separated from the apron and rolled up or passed onto further processing.
  • the apron 24 then passes through a pair of expander rolls 82 and 84 which serve to maintain the apron in a smooth, fully open width condition prior to returning to the starting point to pick up a fresh section of web. Where a double apron is employed, it also is returned to the starting point and, again, expander rolls or their equivalent may be utilized.
  • a funnelled bottom wall 86 for collecting condensed solvent vaporized by the drying cans.
  • a relatively large condenser (not shown) is mounted along side the main tank and the vaporized solvent from the drying stage is directed by duct work to the main condenser.
  • the resulting condensate is passed through a separator or other purifying means prior to reuse,
  • a small condenser 88 is provided at the right-hand end of the tank and also discharges onto the inclined channel 72 for return to the sump within the main unit.
  • the apron or aprons permit any fragile web material to be held tightly in direct contact against the surface of the heated cylinders without stretching the fabric. Double aprons will provide tight contact against all cylinders while a single apron will offer best contact as the web is carried down under the lower surface of the cylinders.
  • the material may be washed and dried quickly and easily without being subjected to distortion, stretching or the like.
  • the entire process may be carried out without wetting the material with water and this has an advantage over steam drying techniques. If steam is sprayed directly against the fabric to cause the solvent to vaporize, the steam will condense and wet the material. In addition, the water and solvent will then have to be separated before the solvent can be reused.
  • the present invention eliminates the problem of wetting the material with water and delivers the material in a relaxed, undistorted condition on a continuous basis.
  • FIG. 2 of the drawings there is illustrated a modification of the invention and in this embodiment all of the recovery stills are located within the main tank housing.
  • the wet-out and the drying sections are arranged in a manner similar to FIG. 1, however, in this embodiment condensate from the drying stage as well as overflow from the solvent sump tank are collected in a condensate well at the base of a main tank housing 12.
  • cooling coils and suitable conduits and pumps are provided for delivering the condensed solvent into the sump tank, as required.
  • the washing tank is provided with a washing apparatus of the sort disclosed in commonly assigned copending application, Ser. No. 670,837 now US. Pat. No. 3,513,671, filed Sept.
  • the washing apparatus of FIG. 2 includes a longitudinally corrugated r0- tary drum 102 disposed below the surface of the liquid.
  • Mounted in generally tangential relation to the drum 102 are relatively small planetary reels 104, each provided with an array of evenly spaced smaller nip rolls I06 adapted to mesh with the corrugations of the larger drum I02.
  • the web and belt are fed into the liquid around the drum and out.
  • the corrugated drum rotates along with the planetary reels. the nip rolls force the web and belt into the corrugations, squeezing the liquid through the fabric and enhancing the contact between the web and the liquid.
  • a continuous belt or apron I08 is illustrated in the FIG. 2 embodiment and may also be included in the FIG. I embodiment if the second belt 26 is not employed.
  • the belt 108 travels about rolls I10 and 112 which guide the belt I08 into and out of superimposed contact with the web 10 and belt 24.
  • Apparatus for continuously processing a running web of knit material or the like comprising a. a substantially closed housing formed with a tank adapted to contain a quantity of liquid,
  • heating means including a plurality of heated rotatable drums in said housing and along the path of travel of said web for vaporizing liquid from said web
  • a condensing system in said housing for condensing vaporized liquid for condensing vaporized liquid, a portion of said system being disposed above said tank and formed with a condensate drain onto said web between said tank and said nip rolls.
  • Apparatus according to claim I including liquid discharge means disposed above said tank for delivering a flow ofliquid over said web.
  • Apparatus according to claim ll including a second belt forming a continuous loop and second guide means for guiding said second belt into superimposed relation against said web and said first mentioned belt as said web enters said tank and separating said second belt from said web as said web travels out of said tank.
  • Apparatus according to claim ll including a corrugated rotary drum disposed in said tank for engaging said web and at least one cooperating corrugated roller adjacent thereto for nipping said web as it is carried by said drum through said tank.
  • Apparatus according to claim ll including belt tensioning means engaging said belt for maintaining predetermined longitudinal tension thereon.
