Definitions

  • an object of the present invention to provide a new and improved apparatus for treating a running fabric web.
  • a more particular object of this invention is to provide a new and improved apparatus for solvent scouring a running'web on a continuous basis providing a high washing action with a minimum volume of solvent.
  • a further object of this invention is to provide a novel apparatus for drying the fabric without distortion thereof.
  • This invention features the apparatus for treating a running fabric web, comprising delivering the web in a tensionless flat condition onto a conveyor and carrying the web past a plurality of scouring stations with each station re-cycling a portion of solvent drains as well as a portion of the adjacent station drains, then past a final station wherein clean, fresh solvent is applied.
  • the web is then carried through a suction station where a portion of the solvent is removed and then past an optional application station where a chemical may be applied to the web.
  • the web is then carried into a drying chamber BRIEF DESCRIPTION OF THE DRAWINGS
  • the FIGURE is a sectional view in side elevation, somewhat schematic, of a fabric treating apparatus made according to the invention.
  • the reference character .10 generally indicates a fabric treating apparatus comprised of modular housing sections 12 and 14 detachably connected to one another along a vertical joint 16.
  • the forward section 12 serves as a solvent scouring chamber while the after section 14 serves as a drying chamber.
  • the apparatus 10 is mostly enclosed within a housing fonned by side walls 18 and end walls 20 and 22, bottom walls 24 and 27 and top walls 20 and 30.
  • a running web 32 which may be in flat open width form as for woven fabrics or in flat tubular form as for knit fabrics, is carried up in an inclined conveyor 34 and dropped down onto an inclined chute 36 extending into the first stage 12 and terminating slightly above the upper reach of a horizontally extending conveyor 38.
  • a feeler 40 is located between the discharge end of the chute 36 and the start of the conveyor 38 to sense the tension on the web 32 as it is delivered onto the conveyor.
  • the feeler is operatively connected to one of the driving rolls for the feed conveyor 34 and serves to control the rate of delivery of the web into the scouring chamber. If the feed is too fast, the web will drape loosely as it comes off the chute whereas if the feed is tooslow, the web will become tensioned. In any event,
  • the feeler will sense the condition and, through the control unit, take corrective action.
  • each group of spray nozzles may be three in number and typically may be in the form of tubes or pipes formed with longitudinal slits or longitudinally aligned perforations adapted to dispense the solvent in the form of a spray against the web.
  • Each set of nozzles is connected by its own conduit 48, 50 and 52, respectively, to its own pump 54, 56 and 58, respectively.
  • Each of the pumps is connected by a conduit 60, 62 and 64, respectively, to a drain tank or a trough 66, 68 and 70.
  • the drain troughs66, 68 and 70 are mounted adjacent to one another in a vertically staggered relation with the tank 66 below the level of the tank 68 which, in turn, is below the level of the tank 70.
  • the drains from the nozzles above the conveyor collect in the troughs with most of the drains running down an inclined wall 72 into the first trough 70.
  • the wall 72 is located directly below a nozzle or spray bar 74 positioned at the end of the nozzle sets 42, 44 and 46 and connected by a conduit 76 to a still 78 whereby clean, fresh solvent only will be sprayed onto the web prior to leaving the scouring chamber.
  • the trough 70 in conjunction with the pump 58, conduits 62 and 64 and sprayheads 46 re-circulate relatively clean solvent at this stage since it is closest to the fresh solvent coming from the nozzle 74.
  • the overflow from the trough 70 goes into the middle trough 68 which also receives some drain from its associated nozzles directly over it and which drains include those impurities washed down by the set of nozzles 42.
  • the second set of sprayheads 44 wash the' fabric with solvent that is less clean than the solvent going through the sprayheads 46, yet cleaner than those at the first set of heads 42.
  • the overflow from the trough 68 is to the trough 66 which is recycled to the first set of nozzles 42 by means of a pump 54.
  • the overflow from the trough 66 is to a collection drain 80 which feeds through a line 82 and is pumped back to the still 78 where the solvent is purified and returned to the scouring station through the line 76.
  • a storage tank 84 is provided and connected to the still to compensate for losses due to evaporation, leakage and the like.
  • the scouring action is further enhanced by vibrating the web as it passesthrough the scouring station. This may be done by means of an eccentrically rotated roller 85 mounted below the upper reach of the conveyor 38.
  • the conveyor belt 38 is in a form of a foraminous screen or mesh material which permits the solvent to pass freely therethrough.
  • the cleansing action is multiplied. For example, assuming the pumping capacity from the still is 600 gallons a minute, this washing volume would be multiplied approximately four times by the re-cycling stages, the multiplication factor depending upon the number of re-cycling stages.
  • the conveyor 38 carries the web under a spraybar 92 adapted to deliver a liquid chemical over the width of the fabric.
  • the spraybar is connected by a line 94 and pump 96 to a storage tank 98.
  • a drain board 100 is located below the upper reach of the conveyor and under the spraybar 92 to collect the runoff from this station.
  • a drain return line may be provided to recover excess chemical and return it to the storage tank 98.
  • Various types of chemicals may be applied at this station such, for example, a finishing chemical sold under the trademark Scotchguard by the 3M Company.
  • the web is transported into the drying section 14 and is discharged from the conveyor 38 onto the upper reach of a conveyor 102, preferably of an openwork material to permit vapors to pass therethrough.
  • the conveyor 102 is disposed slightly below'the level of the conveyor 38 and a feeler 104, similar to the feeler 40, is provided to sense the tension of the web as it moves from one conveyor to the other.
  • the feeler 104 is operatively connected to the conveyor 102 to control the speed thereof to prevent tensioning of the web and also to prevent the web from bunching up. Insofar'as the web will be drying while it is on the conveyor 102, it will undergo dimensional changes to some extent depending upon the material. Thus, unless compensation is provided in the speed of the conveyor 102, the web would tend to tension longitudinally with respect to the section of the web passing through the scouring station.
  • a vibratory motion is introduced to the web.
  • the vibratory action is provided by means of an eccentric roll 106 below the upper reach of the conveyor belt 102 and rotated by any suitable means such as a motor and the like. Rotation of the eccentric roll 106 will agitate and vibrate the conveyor belt together with the web, tending to shake out droplets of solvent within the web fibers and also fluffing up the web material in the process.
  • the main drying action in the drying chamber is provided by means of a combination of super-heated solvent vapor and air which is delivered through ducts I08 and 110 disposed above the upper reach of the conveyor 102 and provided with openings along their bottom walls to direct heated gas down against the web. Air and solvent vapors are continuously re-circulated within the drying chamber and provide a highly effective medium for drying the fabric. The mixture of air and solvent along with any solvent flashed off from the web by the drying action, is drawn down towards the bottom of the drying chamber through condensers 112 mounted across an opening formed in a horizontal supporting wall 114.
  • a portion of the vapors passing through the condensers will condense and collect in one of the troughs formed in a drainboard 116 and these drains are then returned to the still for re-use.
  • the remaining gaseous mixture of air and vapor is drawn into a centrifugal blower I18 and forced into a manifold 120 across which is mounted a heater 122.
  • the heater superheats the vapor for optimum drying action prior to distribution through the transversely extending ducts 108 and 110 disposed across the conveyor 102 and communicating with the heater manifold.
  • the web is transferred upwardly to another horizontal conveyor 124, the speed of which is controlled by means of a feeler 126 and which also is provided with a vibrator 128.
  • Ducts 108' and-110' are located above the conveyor as in the first instance.
  • another discharge head 130 Disposed above the upper reach of the conveyor 124 is another discharge head 130 providing a second fabric finishing station wherein a chemical, which may be the same as or different from the chemical at the first finishing station, is applied to the web.
  • the head 130 is connected by a conduit 132 and a pump 134 to a chemical storage tank 136.
  • the web is then carried along a reversely extending path and is fed up onto the uppermost conveyor 138, the speed of which is controlled by a feeler 146 where it is carried upwardly and outwardly through the end of the drying chamber to be delivered to a take-up roll or transferred to other processing equipment.
  • the scouring and drying sections may be separated to permit the addition of other fabric processing equipment, to extend the length of theconveyors, to add heating sections, provide more finishing stations, provide additional washing action, or the like. This provides a high level of flexibility since the units may be used together, in
