Definitions

  • This invention relates to a jet dyeing apparatus for dyeing textile materials which is particularly desirable for use in dyeing textile fabrics in rope form.
  • the fabric to be treated is continuously circulated through a treatment zone or transport tube in which dye liquor is applied to the fabric under pressure.
  • the pressurized liquor serves a dual function, namely to dye the fabric as well as to impart movement to the fabric rope which is conveyed from the transport tube into a fabric storage chamber.
  • the fabric is submerged in excess dye liquor and moves through this chamber suspended in the liquor until it is removed from the opposite end for conveyance through the transport tube whereupon the cycle is repeated.
  • pressurized dye liquor is applied to the fabric in the fabric transport tube.
  • the tube typically includes at least one peripheral liquor sprayer or "P.L.S.” which is designed to apply the liquor under pressure to the fabric about its complete circumference. It is particularly desirable to apply the pressurized liquor in a way which enhances the interchange between the dyestuffs and the fabric in order to enhance the uniformity of the dye application to the fabric. In order to dye the fabric successfully, however, it is also necessary that the fabric travels at relatively high speeds through the transport tube, but while still ensuring that the desired level of liquor-fabric interchange occurs.
  • Sturkey proposes the use of a modified j-box and an elongate liquor transport tube which has a steep upward incline in order to ensure, according to Sturkey, that the treated fabric will be conveyed through the transport tube with relatively reduced surface degradation.
  • the problem in the Sturkey device is that the use of a single liquor sprayer at the inlet in combination with the elongate tube, means that extremely high pressures must be used in order to maintain any reasonable throughput through the jet dyeing machine.
  • Ekstroem advocates the use of a perforated region in the undulated pipe for the purpose of reducing the rate of travel in the fabric, ostensibly for the reason of reducing turbulence at the discharge point, but with the result that substantial liquor will be drained from the fabric while it is still in the transport chamber, and with the additional result that the capacity of the apparatus will be unduly restricted.
  • a plaiting nozzle is oscillated transverse to the direction of travel of the fabric through the fabric transport tube and is also preferably oscillated in a longitudinal direction (using the hood 21 in Mezzera, for example) or by axial movements of the discharge nozzle in accordance with the embodiment shown in Figure 4 of Mezzera.
  • the transverse and longitudinal action results in a parallelipiped arrangement of the fabric which is said to improve the stability of the stored fabric in the j-box in order to attempt to minimize occurrences of fabric entanglement within the j-box or storage chamber.
  • the entire fabric transport tube including a fixed plaiting nozzle, may be oscillated in a direction transverse to the main path of travel of the fabric. While this approach forms generally transverse folds in the fabric, it substantially limits the production capacity of the apparatus and increases wear and tear on the entire assembly. Furthermore, the fabric is deposited in the fabric storage chamber in a generally arcuate pattern which is inherently unstable and which wastes the available capacity in the fabric storage chamber.
  • the desired object of maximizing capacity while minimizing tension and creasing of the fabric in the "J"-box leading to entanglements is achieved by providing a jet dyeing apparatus as defined in claim 1.
  • increased capacity may be attained through the use of a fabric transport tube which includes a plurality of peripheral liquor sprayer systems or other jets which are fed with dyeing liquor from a common supply.
  • the highest fabric speeds may be achieved at the lowest possible water pressure.
  • the first peripheral liquor sprayer is preferably placed at the entry end of the fabric transport tube, i.e. the fabric inlet to the fabric transport tube, while a second peripheral liquor sprayer is preferably positioned just beyond the midpoint of the fabric transport tube.
  • the section of the fabric transport tube between the first peripheral liquor sprayer and the approximate midpoint of the transport tube defines a first transport zone which is preferably downwardly inclined at a mild angle while the section of the fabric transport tube after the midpoint and containing the second peripheral liquor sprayer, is generally upwardly inclined toward the plaiting nozzle to define a second transport zone.
  • the use of a plurality of peripheral liquor sprayers will increase the overall volume of liquor traveling through the fabric transport tube with the further result that greater volumes of excess liquor will be deposited by the outlet nozzle of the plaiter onto the orderly fabric pleats previously formed by the plaiting mechanism.
  • the invention may additionally include an excess liquor bypass which may be desirably formed integrally with the outlet nozzle of the plaiting mechanism. The excess liquor bypass is formed on the outer curve of the elbow defining the outlet nozzle and adjacent the defined path of travel for the fabric.
  • the excess liquor will travel through a perforated plate in the outlet nozzle so that the liquor is diverted outside the main area of the liquid treatment chamber so that a relatively small percentage of dye liquor entering the liquid treatment chamber falls directly on the fabric which has been plaited.
  • the excess liquor may then travel through a distinct path of travel and may be in fluid communicating relation to the chamber through perforations or the like so that the liquor may then be recirculated to the header associated with the peripheral liquor sprayers.
  • the unique plaiting system as described herein deposits the fabric in the storage chamber in an orderly manner so that the full width of the chamber is utilized and so that each new plait of fabric is deposited in overlying relatively straight folds square to the centerline of the storage chamber. In this manner, the fabric remains relatively undisturbed until it reaches the front exit of the storage chamber and helps to ensure that entanglement of the stored fabric as it moves through the storage chamber will be minimized or avoided completely.
  • the use of a plurality of liquor sprayers as described in conjunction with the preferred transport tube enables the attainment of relatively higher operating speeds while minimizing the likelihood of fabric degradation in the process.
  • This invention also relates to the method of dyeing a length of textile material as defined in claim 7.
  • the jet dyeing apparatus comprises a housing H which includes a liquid treatment chamber or j-box 10 in the lower portion of the housing and a fabric transport tube 11 in the housing above the liquid treatment chamber.
  • the fabric 1 enters the fabric transport tube 11 with the assistance of a driven rotating cylinder 2 as is customary in jet dyeing apparatuses of this general type.
  • the fabric enters the fabric transport tube 11 at a fabric inlet or entry end 16 and is immediately contacted with liquor from a jet apparatus or peripheral liquor sprayer 3 which is supplied with liquor from a common supply or header 12.
  • the preferred peripheral liquor sprayer sprays liquor on the fabric in a manner which both dyes the fabric and which also serves to transport the fabric 1, which is typically in continuous rope form, along the longitudinal direction of the fabric transport tube 11 and ultimately to the plaiter mechanism 7.
  • the fabric transport tube 11 preferably includes a plurality of peripheral liquor sprayers including the first aforementioned sprayer 3 at the inlet or entry end 16 to the fabric transport tube 11 and a second peripheral liquor sprayer 4.
  • the two peripheral sprayers are preferably supplied by a common header 12.
  • the second peripheral liquor sprayer 4 is preferably positioned downstream of the first peripheral liquor sprayer 3 and closely adjacent the midpoint 20 of the fabric transport tube 11. As shown, the nozzle of the second peripheral liquor sprayer 4 is spaced approximately 135mm from the approximate midpoint 20.
  • the fabric transport tube 11 defines a generally horizontal centerline C ( Figure 3).
  • the transport tube 11 is preferably downwardly inclined in the region between the entry to the fabric transport tube 16 at the first peripheral liquor sprayer 3 and then upwardly inclined beginning near the midpoint of the fabric transport tube 20.
  • a first transport zone is defined commencing at the fabric inlet to the fabric transport tube 16 where the first peripheral liquor sprayer 3 is positioned, and then extending at a generally downward mild incline to the approximate midpoint 20 of the fabric transport tube 11 whereupon a second transport zone intersects the first transport zone at the lowermost point in the fabric transport tube and then extends at a gentle slope upwardly at an incline to the outlet of the fabric transport tube defined by the means mounting the plaiter mechanism 7.
  • the fabric transport tube will have a shallow v-shaped outline in profile. In this manner, the fabric transport tube 11 will be flooded with dye liquor to improve the liquor fabric interchange within the fabric transport tube, but without significantly impeding the progress of the fabric through the transport tube. In addition, this design creates a slight turbulence which tends to rearrange the fabric folds leaving the first transport zone prior to treatment in the second peripheral liquor sprayer 4.
  • the effective pressures at the nozzles of the peripheral liquor sprayers 3 and 4 may be varied in accordance with the invention, but will typically range from 0.1 to 0.5 bar which will correspondingly affect the speed of travel for the fabric 1 through the fabric transport tube 11.
  • the rate of travel for the fabric attainable with this arrangement is approximately 110 meters per minute at 0.10 bar inlet pressure and rises to a rate of approximate 240 meters per minute at a corresponding water pressure of 0.40 bar at the peripheral liquor sprayers 3 and 4.
  • the angle defined by the interior diameter of the fabric transport tube and the sidewall of the nozzle within the peripheral liquor sprayer may also be varied but as shown is approximately 30 degrees.
  • the included angle defined between the two sections of the fabric transport tube at the midpoint 20 also may be varied in accordance with the invention, but will preferably fall in the range from about 110 to about 180 degrees and preferably in the range from about 130 to 160 degrees to define the slight "v" shape in profile. As shown in Figure 3, the particular preferred arrangement defines an included angle of about 150 degrees at the midpoint 20 which is the junction between the first transport section and the second transport section.
  • the overall length of the fabric transport tube 11 also may be varied in accordance with the present invention as may be the approximate length of the first and second transport zones defined by the fabric transport tube.
  • the length of the first transport zone which is defined by the distance from the entry point 16 to the fabric transport tube 11 to the approximate midpoint 20 may vary in the range from 200 to 800 millimeters and is approximately 500 millimeters in the particular arrangement as depicted in the drawings.
  • the length of the second transport zone also may be varied over similar ranges and is preferably approximately the same length as the first section and at approximately the same positive angle corresponding to the negative angle applied in the first transport zone, so that the outlet of the fabric transport tube at the plaiting mechanism 7 at the bearing 5 will lie at approximately the same elevation as the entry point 16 at the first peripheral liquor sprayer 3.
  • a unique plaiting mechanism 7 is provided.
  • the curved plaiter 7 directs the fabric vertically downwardly into the liquid treatment chamber or treatment chamber 10 ( Figure 1).
  • the curved plaiter 7 is preferably of rectangular cross-section throughout its length and may be a square.
  • the base of the plaiter is preferably mounted on a circular bearing 5 at the exit end of the fabric transport tube and preferably comprises a stainless steel spherical ball roller bearing 5 which is rotatably fixed to the end of the fabric transport tube. In this manner, the entire plaiting mechanism 7 may be oscillated rapidly about the centerline of the transport tube C.
  • the plaiter 7 defines an outlet nozzle 15 which extends downwardly into fluid communicating relationship with the inlet to the liquid treatment chamber 10.
  • the plaiting mechanism is mounted on a circular bearing 5 about which it may be oscillated in any known fashion through the reciprocating action of oscillation means 6.
  • the plaiter may be oscillated at rates ranging from 10 to 50 complete strokes per minute and travels in a path which preferably defines a straight line across the complete width of the inlet to the liquid treatment chamber.
  • the outlet nozzle 15 defined by the plaiter 7 is oriented approximately 90 degrees to the chamber centerline and is also substantially perpendicular to the longitudinal axis or centerline C of the fabric transport tube 11. If the tube 11 is substantially straight then the angle defined between the centerline C and the nozzle 15 will be around approximately 90 degrees. Since the centerline C of the transport tube 11 will vary in its geometry from a straight line, and particularly in accordance with the preferred embodiments, the exact angle may vary and it is only important that the outlet nozzle 15 is downwardly directed and reciprocates along a generally linear path of travel which is transverse to the centerline and such that the fabric material 1 passing through the transport tube 11 is deposited in the inlet of the liquid treatment chamber in overlying relatively straight folds.
  • the angle defined between the second transport zone defining a portion of the centerline C and the outlet nozzle 15 will be less than about 90 degrees. In this manner, the path of travel of the nozzle 15 will be a straight line across the width of the storage chamber 10 in contrast to prior art devices.
  • the present Invention also preferably includes a liquor bypass 8 in the plaiter assembly 7 which includes a bypass nozzle 9 which preferably communicates with the storage chamber through a path which is longitudinally spaced apart from the main path of travel of the fabric entering the treatment chamber 10.
  • a liquor bypass 8 in the plaiter assembly 7 which includes a bypass nozzle 9 which preferably communicates with the storage chamber through a path which is longitudinally spaced apart from the main path of travel of the fabric entering the treatment chamber 10.
  • this invention also relates to the resulting method of dyeing a length of textile material as described hereinabove which includes the steps of guiding a length of textile material through a generally horizontally directed transport tube while applying a jet of liquid dye onto the material in the tube to dye the fabric and advance it through the transport tube.
  • the textile material is then advanced downwardly from the exit end of the transport tube and reciprocated along a linear path of travel transverse to the direction of advance through the transport tube so as to form overlying relatively straight folds of the material in the treatment chamber.
