Definitions

  • the present invention relates to a process for embellishing by dyeing fabrics such as fabrics, knits, nonwovens or similar articles in the form of a breathable sheet; it also relates to a device allowing the implementation of this process.
  • the most commonly used solution consists of using a thickener.
  • FR-A-2 319 433 has also been proposed (as well as to a certain extent in FR-A-2 420 432) embellishment methods by coloring fabrics or similar products which consist in laying flat the article to be embellished, subjected to a suction and to project the dye against the surface by means of nozzles.
  • the dye is delivered in the form of liquid jets or in the form of spraying.
  • the jet the nozzle is as close as possible to the fabric and the printing dispenses with stencil.
  • a stencil is used which allows only finely drawn drawings on thick supports (carpet), this because of the propensity that a liquid has to fuse.
  • DE-A-2 932 124 describes a device using a dye dispensing head by means of nozzles, but such a device does not make it possible to obtain colored patterns having extreme finesse, possibly by superimposing several different dyes.
  • a thickener into the dye, and using it in the liquid state, optionally in the form of a jet obtained by means of a nozzle.
  • it is vaporized (or atomized) in the form of a mist, that is to say in a state of extremely fine fragmentation, even molecular dyes, which makes it possible to apply it to the fabric, also thanks to the suction produced below the latter, without it diffusing on the surface while penetrating to the core and this, without wetting it significantly, the current of air produced by the suction which also allows said dye mist to be transported and controlled.
  • the atomization drying practically instantaneously, it is therefore possible to immediately superimpose the prints while retaining their extreme fineness, while the wet prints lose a large part of the finesse possibilities.
  • the absence of thickener allows absolutely perfect dye overlays; in fact, the thickener of the first impression always more or less screens the next one and thereby prevents transparent repairs.
  • this instant drying allows the immediate winding of the printed fabric.
  • the stencil makes it possible to obtain complex gradations, to dye solid or gradient fabrics, to obtain stripes and this, in a great complexity of coloring which is impossible to date.
  • the method according to the invention can be implemented with materials which are difficult to print such as for example knitted fabrics, the treated fabrics being able to be dense or on the contrary very light, for example being in the form of muslin .
  • the fabric When the dye is deposited, the fabric can be kept either fixed or, on the contrary, be moved at a constant speed or not.
  • the power of the suction exerted under the fabric during the dye deposition phase will depend on the material to be treated and more particularly on the porosity that it presents.
  • This suction must be adjusted not only to produce a very large vacuum but also to cause a large flow of air through the article.
  • the depression will, depending on the article to be printed, be equivalent to ten to a thousand millimeters of water column and must produce an air flow of between 2000 and 5000 m3 per hour.
  • the device according to the invention will have the following characteristics.
  • the suction table will consist of a watertight box fitted with a suction turbine.
  • the table top consists of a structure, on the one hand offering the least possible resistance to the passage of air while being, on the other hand, sufficiently resistant to the depression caused under the tissue.
  • the dimensions of this table will depend on the dimensions of the fabric to be treated.
  • a shutter may be used to delimit the suction surface of the table, the surface left free by said shutter being a function of the dimensions of the decoration to be made.
  • the suction turbine will have a capacity proportional to the surface of the fabric to be treated and must allow, as said previously, not only to create a strong vacuum below the article but also to cause a large air flow through the article.
  • This flow rate will depend on various parameters, namely in particular the texture or density of the fabric as well as the surface left free by the shutter or the stencil used; this flow rate must be sufficient not only to make the dye penetrate inside the fabric but also to channel the mist of vaporized or atomized dye between the outlet of the nozzles and the surface of the fabric.
  • Maintaining and positioning the fabric on the table top can be achieved in different ways.
  • synchronization means allowing the fabric to be moved step by step (photocells, tracking cameras, feelers, clamps between physical stops, etc.) are provided.
  • the synchronization system could be much more mechanical since the treadmill is not subject to any distri- bution.
  • airbrushes can produce variable sprays in density and concentration, either by the diameter of the nozzles used, or by modifying the dye / air parameter.
  • such airbrushes include a compressed air line, a dye supply line, an opening and closing valve and a flow control system.
  • These airbrushes will be used in the form of ramps made up of a set of fixed or removable airbrushes positioned on a support.
  • the outputs of the airbrushes will, in accordance with the invention, be placed at a relatively large distance from the surface of the fabric to be decorated, this distance being at least of the order of five centimeters but advantageously being between ten and fifty centimeters.
  • each airbrush being moreover supplied by one or more dye ducts (or of various other products), these ducts being able to be alternately closed or opened by means of a system of suitable valves, to allow an instant change of colors or products.
  • the arrival of cleaning products from a purge and air intake system facilitates the various operations necessary for their simultaneity.
  • the various controls for air intake, opening, closing of airbrushes, permutation of dyes or products, opening and closing of solenoid valves can be carried out either mechanically or by an appropriate electronic system (process computerization).
  • the adjustment of the flow rate depends on the work to be carried out.
  • the arrangement of airbrushes can be achieved in different ways.
  • the airbrushes can be aligned (dis linear position), a determined number of airbrushes being juxtaposed at variable or fixed distances on the same axis.
  • the airbrushes can be arranged independently or in a group, each having autonomy of movement on a given plane.
  • the two forms can be multiplied and / or combined.
  • the two aforementioned provisions make it possible to fulfill different functions.
  • these two arrangements can also have in addition to their horizontal movements a vertical displacement.
  • the stencil can take different forms which may correspond to different uses.
  • the stencil can thus, for example, be in the form of a frame used in a manner similar to traditional printing methods (fixed, on rail, etc.).
  • the stencil consists of a frame on which is stretched a fabric made up of large stitches (one or two millimeters at most) whose threads are as fine as possible, this fabric having the characteristic offer as little resistance to air as possible.
  • the motif to be reproduced is produced using existing photogravure methods.
  • the stencil can be in the form of loose sheets used in the case of a winding system.
  • the stencils can also be in the form of rotating cylinders, for example in the case of continuous printing.
  • they can also be in the form of more or less long bands, fixed or circular, said bands then being scrolled.

  • This fabric (3) comes from a food roller (4) and is wound, after decoration, on a winding roller (5) disposed on the other side of the table (1).
  • the passage of the fabric (3) on the table (1) can be done either step by step, or at constant speed, or at progressive speed.
  • the table top (2) of the table (1) comprises, at least in the zone corresponding to that where the colored pattern is to be produced, a part (6) permeable to air.
  • the entire surface of the table can be breathable in which case an additional cover (7) can be used to mask the areas outside the printed pattern.
  • the table (1) is in the form of a sealed box subjected to the action of a suction system making it possible to create a depression on the surface of the plate (2).
  • This suction system can be constituted by a turbine (not shown) whose capacity is proportional to the surface of the fabric to be colored and whose flow rate can be modified as a function of the texture or density of the fabric and the surface of the decoration to be made. , surface possibly delimited by an additional shutter (7).

  • the suction table being in operation, it is possible, in this embodiment, to obtain, by the diffusion of the coloring spray, a base dye of perfect unison. This coloration can vary as a function of the speed of movement of the fabric, the intensity of the spray jet, the height at which the ramp (9) is positioned relative to the surface of the fabric, by feeding the airbrushes themselves.
