Definitions

  • Our present invention relates to the continuous production of patterned sheet material and, more particularly, to the patterned dyeing of continuous webs of textile fabrics, synthetic-fiber sheets and the like.
  • the continuous dyeing of fabrics and other sheet material in the form of continuous webs has been carried out heretofore in such manner as to produce a uniform coloring of the web or various color patterns.
  • the web is either passed into a bath of the coloring material or sprayed continuously with the dyestutf from one or more nozzles as the web is displaced along a predetermined transport path.
  • Color patterns can be produced continuously, according to earlier proposals in this field, by regulating (i.e. turning on and off the dye stream emanating from one or more of these nozzles in a programmed manner.
  • the flow through the spray nozzles is conventionally regulated by the usual programming devices including electrical, mechanical or pneumatic mechanisms designed to control the valve and other elements regulating the rate of flow through the nozzle apertures.
  • Valves for this purpose are, moreover, provided with relatively massive valve members whose movement necessitates the overcoming of considerable inertia and, therefore, the use of relatively large, powerful and somewhat sluggish control devices (e.g. solenoids, pneumatic pistons, and mechanical lever arrangements).
  • control devices e.g. solenoids, pneumatic pistons, and mechanical lever arrangements.
  • the principal object of the present invention to provide an improved method of and apparatus for the pattern dyeing of textile fabrics and other continuous webs at relatively high speed but with good definition between the colored and uncolored regions.
  • a more specific object of this invention is to provide an apparatus of the character described enabling highspeed and low-inertia control of the elements regulating the dye jets.
  • a further object of this invention is to provide a method of pattern dyeing textile fabrics and other webs which permits fine patterns to be repeatedly and reproducibly generated, and which results in a saving in dyestuff while precluding blotching and running of the dye on the web.
  • a method for the pattern dyeing of a continuously moving dye-retentive web along a transport or processing path which includes the steps of circulating a dyestufi along a closed path at least a portion of which lies proximal to the web, and selectively diverting a portion of the dyestuff and projecting this portion in finely divided form out of the transport path against the web while the remainder of the dyestuff continues on its circulation path.
  • the method involves the use of either of two different principles for effecting transfer of the dyestuff from its closed circulating flow to the fabric.
  • the dyestuff is directed generally transversely to the fabric web during the course of circulation and by the circulating means, but is selectively interceptable by deflecting means capable of redirecting the project stream along the circulating path.
  • the dyestuif is conveyed along a path which can extend generally parallel to the web or, in more precise terms, along the web for a portion of its travel or generally in the direction of travel, while the deflecting means selectively diverts a portion of the dyestuff out of its circulating path and projects it in finely divided form against the web.
  • the dyestutf is continuously circulated while only a portion thereof is projected against the web and is retained thereby.
  • An important advantage of the present invention is that the continuous circulation of the dyestuff imparts to the sprayed material a velocity enabling it to come into contact with the fabric while the control means is only required to selectively deflect either the return stream out of the projected stream or the projected stream out of the return flow to effect pattern dyeing.
  • the control means can be provided with programming means coupled with the web-displacement means for establishing the pattern to be applied to the web.
  • a more specific feature of this invention resides in the provision of pneumatic means for deflecting the continuously circulating dyestuff in the manner discussed above.
  • the pneumatic means can include a multiplicity of pneumatic jets directed at respective spray streams of the dyestutf projecting transversely and in the direction of the web so as to deflect the projected streams along a return path.
  • the pneumatic jets can be directed against the web and can serve to project finely divided particles of the dyestutf from a freely-falling curtain thereof out of the circulating path and into contact with the dyestuif.
  • a desired patterned effect is produced by the intermittent training of these jets upon laterally juxtaposed portions of a substantially cohesive curtain of liquid dyestuff, occupying a section of its closed-circulation path, in a zone proximal tothe web but separated therefrom by an air space, the pressure or absence of these jets causing the liquid dyestutf of the corresponding film portions to be selectively deviated from that path onto the moving web.
  • the deflecting means comprises an intercepting element selectively positionable in front of an outlet through which the dyestutf is discharged for alternatively diverting it along a transport path and permitting it to stream into contact with the web.
  • pneumatic jets are provided as the deflecting means, fixed interceptors positioned adjacent an outlet opening toward the web preferably cooperate therewith to divert the deflected stream of dyestuff along its transport path.
  • the pneumatic jets themselves may be controlled by valve members for the selective blocking and unblocking of the apertures of the jets or, according to a highly desirable arrangement, by the selective diversion of a. high-velocity stream of air into and out of alignment with such aperture.
  • valve means do not directly block or unblock the passage from which the flow of dyestuif emanates.
  • the intercepting means can, moreover, be part of a movable shield (e.g. formed as a continuous belt) whereby the sprayed particles can pass through the gaps in the shield formed by the interceptor means.
  • the shield can, consequently, form the template according to which the pattern is produced.
  • the force field may also be formed by one or more pneumatic jets directed transversely to the dyestuff stream projected toward the web.
  • pneumatic is used herein to distinguish the deflecting fluid, which can be any convenient gas, from the liquidcirculated through the treating station in the proximity of the web.
  • pneumatic fluids suitable for use with the present invention can include ambient air, bottled gases or air fractions as desired.
  • the force field referred to above preferably cooperates with intercepting means in the form of a stationary shield disposed adjacent an outlet opening in the direction of the web and designed to intercept the dyestuff spray when the latter is diverted from this outlet.
  • a multiplicity of parallel force fields will be applied transversely to the projected liquid in at least one row extending perpendicular to the direction of displacement of the web.
  • a row of pneumatic jets may be provided, this row extending athwart the web and having individually controlled airflow rates programmed in accordance with the desired pattern.
  • the force field's can be applied continuously so as to divert the dyestufl along its closed circulating path with deviation therefrom against the web being accomplished by deenergizing or terminating the force fields.

  • FIG. 2 is a view similar to FIG. 1, diagrammatically showing the other of these primary techniques

  • FIG. 1 we show a fabric web 1 which is displaced in the direction of arrow X by suitable transport means diagrammatically represented by a pair of rollers 50, 51.
  • the web 1 can be drawn from a suitable supply roll and, after passing the dyeing or treating station, can enter a drying stage and/or suitable washing, rinsing and dyesetting stages for subsequent fabric treatment before being wound again upon a takeup roll.
  • the drive means 50, 51 are synchronized with the programming means 52 which may be of any conventional type and which controls the deflecting means represented generally at 4.
  • the programming means may, for example, include a perforated band bearing the desired color pattern and through which the feelers of respective switch means can pass to electrically energize respective control elements of the deflecting means 4.
  • the programming means coupled with the web-displacing means may also be constituted by photo-electrically scanned pattern-establishing tapes, cams, timing devices and similar programming controls (e.g. of the Jacquard type).
  • a liquid dyestuff or other treating material is displaced from a reservoir 5 by a circulating pump 6 in a closed path represented by the arrow Y and the reference numeral 53, at least a portion of the path lying in proximity to the web 1.
  • this portion of the closed circulating path of the liquid dyestuff is formed by a freely cascading curtain 3 of the dyestuif discharged from one or more apertures 2 and collected by an interceptor 10 on the side of the curtain 3 opposite the outlet 2.
  • the interceptor 10 is constituted as a trough communicating with the reservoir 5.
  • this aspect of the present invention requires that the closed circulating path of the liquid dyestufi include a portion or segment wherein the dyestutf is displaced generally parallel to the web 1 while a deflecting means is selectively operable to divert a portion of the dyestuff out of this path and to project it against the web.
  • the deflecting means 4 provided at the side of the liquid curtain 3 remote from the web 1 is adapted to apply a deflecting-force gradient generally transversely to the curtain of liquid and to project at least some of this liquid against the web from the curtain 3 and pattern dye the web 1.
  • the force field or gradient is indicated by the arrow 4 which can represent a row of pneumatic jets individually controlled to intercept the dyestuif curtain at spaced locations athwart the web and carry the dyestufi into contact with the web.
  • the force field can be constituted by electrostatic or electromagneic means as will be apparent hereinafter.
  • pneumatic jets When pneumatic jets are employed, the air flow at the respective gap can be controlled by blocking and unblocking valves at the jet nozzles or apertures, by selectively aligning and disaligning high-velocity air streams with the respective apertures, and by other techniques as will become apparent hereinafter.
  • FIG. 1 will thus be readily apparent.
  • the liquid dyestuff is continuously circulated by the pump 6 to and from the curtain 3, a portion of the dyestuif can be selectively diverted by the deflecting means 4 and projected into contact with selected areas of the web 1 as determined by the programming means 52. If the de flecting means is rendered inoperative, the curtain 3 is not deflected and no coloration is imparted to the web.
  • the fabric web 1, transported by the rollers 50, 51 as previously described, does not run parallel to a curtain of the liquid dyestuif traveling along its circulating path.
  • the pump 6a circulates the liquid dyestuff from a reservoir 5a along the path Ya to the nozzle-like discharge apertures 2a which usually direct jets 3a of the liquid dyestufl against the web 1 in a direction perpendicular thereto.
  • the deflecting means 4a acts transversely to the stream of liquid dyestutf 3a emanating from the outlet 2a in the direction of arrow 4a to divert it into an interceptor a when coloration of the web 1 is not required.
  • the deflecting means 4a is again operated by a programmer 52a in step with the displacement of the web 1. Moreover, the deflecting means 4a acts to insure that the liquid dyestuff will be diverted upon its circulating path unless the deflecting means is so operated as to permit an undeflected stream to impinge upon the web.
  • the deflecting means 4a may represent any advantageous system for applying a force field or deflecting-force gradient in the direction of arrow 4a (e.g. individually controlled pneumatic jets, electromagnetic fields or electrostatic fields), or mechanical shield means displaceable generally in the direction of arrow 4a to deflect the projected flow of dyestuff normal to the web 1.
  • a suitable shield means may be formed by one or more fingers disposed above or below the stream 3a of dyestuff directed at the web 1 and individually or jointly displaceable by suitable control means to divert all or part of the dyestutf toward the fixedly positioned interceptor means 10a.
  • the interceptor means 10a can be wholly or partly movable to constitute the shield by being displaced into the path 3a of the liquid projected normal to the gap 1.
  • the dyeing station of FIG. 3 comprises a housing 55 formed with a pressure chamber 7] into which the dyestuff is forced by means of a pump 6] from a reservoir 5 communicating with the return compartment 12 of the housing.

  • the pneumatic jet of air or some other gas establishes a deflecting-force gradient across the stream 3f of dyestuff to produce a force field suflicient to bend the stream into intercepting relationship with a fixed shield 10 which diverts the stream (arrow 3f) to the compartment 12 and thence into the reservoir 5f.

  • FIGS. 7 and 8 discloses a particularly advantageous system according to the present invention.
  • the deflecting-force gradient is provided by pneumatic jets not unlike those of the system of FIGS. 3 and 4, although the jets here are not controlled by individual needle valves and relatively powerful relays, Solenoids or the like but by relatively small electrical energies.

Defiected spray, as indicated by arrow 3k, is intercepted by the fixedly positioned shield 10k and diverted into the collecting chamber 12k whence it is recirculated by the usual pump and reservoir arrangement to the chamber 7k.
  • the deflecting means 4k of this embodiment includes an array of vertical, parallel and transversely spaced resiliently defiectable air tubes 43 anchored at one end in a wall 56k defining a manifold chamber 30k to which air under pressure is supplied via a pump 30k.
  • the tubes 43 pass through a slotted partition 44 whose longitudinal knife edges 44" on opposite sides of the slot traversed by the tubes 43 form fulcra for the latter.
  • Each tube 43 can thus be biased in a counterclockwise sense by a respective adjusting screw 44 about the fulcrum defined by the knife edges until the bottom extremities of the tubes come to rest against the abutment '45.
  • the tubes 43 bear lightly against the abutment 45 in their rest positions in which the ends of the tubes register with respective ports 29k in the base of the respective guide channel 46 which permits each tube 43 to be temporarily and resiliently deflected in the direction of arrow Z.
  • the ports 29k are disposed in respective vertical planes of the tubes 43 and the nozzles 8k so that, in a registering position of each tube and the corresponding port 29k, the respective stream of the dyestutf will be diverted as indicated by arrow 3k along the return circulation path.
  • Each of the tubes 43 is provided with a magnetically attractable (iron) armature 47 which co-operates with a respective electromagnetic system 48 whose two coils are connected in series.
  • the armatures 47 and electromagnetis 48 of adjacent tubes can lie in vertically spaced horizontal planes.
  • Any of the programming means indicated earlier may be used to energize the respective electromagnetic system selectively and in step with the rollers 50k. Selective energization of each electromagnetic device 48 will attract the respective armature 47 in the direction of arrow Z and offset the tube 43 from registry with the corresponding port 29k.
  • the continuing flow of air through the deflected tube 43 is thus no longer effective to divert the corresponding spray stream, which passes through the outlet 14k undeflected and impinges upon the web 1k.
  • the tube 43 returns to its rest position, it again registers with the respective port 29k so that its high-velocity jet of air from chamber 30k is capable of deflecting the corresponding dyestuff stream.
  • An opening in the housing of the deflecting means 4k permits lowpressure escape of air even when all of the tubes 43 are deflected. Since the tubes 43 can be made extremely long, their deflection can be carried out with a minimum of force, thereby enabling low-energy electrical sources and circuits to be used. In this case, therefore, powerful and massive switch arrangements are not required since the pneumatic energy is employed as the deflecting means and also as an amplifier for the output of the programming system.
  • the deflection of the liquid dyestuff streams can be carried out with substantially less mechanical or electrical force than required for conventional nozzle-closure arrangements. It may be stated in general, therefore, that the switch elements and programming devices can be made many times smaller for the purpose of the present invention than has heretofore been possible.
  • the system of the present invention has a greater degree of reliability by virtue of the circulation of the dyestuff which precludes blockage of the discharge opening and nozzles. Since the kinetic energy of the dyestuff is always relatively high as a result of such circulation, the deflection pulses can be quicker and shorter, thereby enabling a finer patterning of the web.
