Definitions

  • the invention relates to a method for dyeing textiles, in which the surfaces of the textiles are colored and additionally machined in such a way that signs of wear occur and that the fabric softens.
  • a method for this in which either the finished piece or the starting material (by the meter) is initially used is completely provided with the color, whereupon the color is washed out up to 95% in a washing and wear process and at the same time the wear effect is achieved during this washing process by adding abrasives, such as sand and / or pumice or the like.
  • the invention is accordingly based on the object of providing a method of the type mentioned at the outset and a suitable device with which it is possible to keep both the energy and material expenditure and the environmental impact as low as possible.
  • the textile pieces can also be soaked with the dye liquor so that the coloring is reflected on the back of the textile, i.e. on the side of the textiles facing away from the brushes, which can be particularly favored by the fact that the dye liquor is subjected to steam, which is drawn in and pulling through the textile pieces favored.
  • the steam is normal wet steam with a temperature of about 100 ° to 120 ° C.
  • a plurality of rotating and driven brushes are provided which act on the textile pieces with the dye liquor and simultaneously process them mechanically.
  • the device expediently consists of a series of horizontally arranged receptacles for the paint liquor with separate outlet channels which are directed at the bristles of the brushes which are arranged rotatably below the containers.
  • At least one conveyor belt rotates continuously beneath the brushes, on which the textile pieces are placed and which bears against the bristles of the brushes under prestress.
  • the brushes not only color the textile pieces, but also treat their surface in the manner described above due to the pretension.
  • the conveyor belt expediently consists of an elastic material provided with openings so that the excess liquor of paint can pass through the conveyor belt into a receiving trough which is expediently arranged below the conveyor belt.
  • a rubber in particular a textile fiber reinforced rubber.
  • the device is designed in such a way that the front and the back of the textile pieces can be processed in the same way in one operation.
  • a deflection device and a second conveyor belt arranged below the first are expediently provided, which are also acted upon by brushes which run above the second conveyor belt.
  • the pieces of textile are thus conveyed into the deflection device by the first conveyor belt, then gripped by the second conveyor belt and pulled through the device for the second time.
  • the deflection device can consist of a guide plate which guides the textile pieces to the second conveyor belt.
  • the individual receptacles have at least one steam line at their outputs are connected, the supply channel for the supply of the paint liquor to the brushes can also supply the steam at the same time, so that the impregnation is brought about. It is also advantageous if at least one compressed air line is arranged in the receptacles, which has outlet openings facing the interior of the individual receptacles, in order to swirl the paint liquor and keep it moving, so that paint components cannot settle.
  • the feed channels for the paint liquor can be shut off individually, appropriate shut-off valves being expediently arranged in the immediate vicinity of the surfaces of the brushes.
  • These feed channels can also be provided with a bypass which feeds the paint liquor past the valves past the second row of processing brushes assigned to the second conveyor belt, so that the closed valves can be bypassed.
  • steam can be expediently fed to the brushes by means of a steam nozzle in the region of the guide plate before the back of the textile pieces are processed, so that steam also dampens the back of the textile pieces to be treated.
  • the intensity of the color in the individual receptacles can be different; Different colors can be provided in the individual containers, and the valves can be adjusted in sections so that either no or a different amount of liquor reaches the brushes.
  • the receptacles can be heated, and the temperatures in the individual receptacles can be different, so that this results in different drawing speeds for the dye liquor.
  • the distance between the axes or shafts of the brushes and the conveyor belts can also be adjustable, so that in this way the pretension with which the weary processing of the textiles is carried out changes.
  • All brushes can be provided with a common drive, for example a chain drive, so that a single drive motor is sufficient to drive the brushes.
  • intermediate brushes can be arranged which have a smaller diameter and are not necessarily used for the application of paint, but only for the wearing treatment of the surfaces of the textiles.
  • the conveyor belts can be subdivided, or the brushes can run at different speeds, so that folds result in the pieces of tissue which are subject to particular wear and tear from the brushes. For the same reasons, it is possible to provide additional intermediate brushes which rotate in the opposite direction to the main brushes which determine the direction of conveyance.
  • Another brush set in each row of brushes can be used as a hold-down.
  • the additional device expediently has a plurality of steam nozzles and at least one supply line for the supply of Heating steam and / or wet steam to the steam nozzles.
  • the paint nozzles can also be acted upon by a compressed air line and / or by the steam lines.
  • a container containing the paint can expediently be assigned to the compressed air line, which there has the shape of a Venturi tube for removing paint particles.
  • the hold-down brushes which are arranged between the processing brushes and have a much smaller diameter than these, are not designed as bristle brushes, as in the previous exemplary embodiments, but as sponge roller brushes, which consist of a cylindrical tubular fitting mounted on a shaft, which is firmly connected to the shaft by gluing or the like.
  • sponge roller brushes has the advantage that due to the stronger adhesion to the piece of textile Crumple zones result, which form a pattern or line formation on the textile piece and have a higher coloration than the surroundings.
  • such sponge roller brushes are generally not used as wearing tools, but rather as crumple and application brushes for the color material.
  • squeezing can also be brought about by the fact that in the area of the folds due to the pushing together of the textile piece in this area there is a stronger color print and thus a reproduction of the pattern thus produced.
  • the hold-down brushes consisting of sponges can be adjusted forwards, backwards, upwards or downwards in their position relative to the neighboring bristle brushes, a different setting of the height of the waves carrying the sponges to the surface of the conveyor belt also being considered is coming. If the shaft is brought closer to the conveyor belt, this means that the cylindrical sponge coating is compressed more strongly in this area, which at the same time means a higher pressure on the textile piece in this area and thus leads to patterns which deviate therefrom.
  • the contour applied by means of the sponges is inherently much clearer than that which, according to the first embodiment, is created by bristle brushes, for example by the hold-down brushes, so that the sponge design in any case, despite the dissolution by the downstream bristle brushes, the contour applied largely preserved.
  • the sponge roller brushes can run in the opposite direction to the neighboring bristle brush rollers, which leads to a further increase in the resolution of the contour due to the relative movement caused thereby.
  • the textile pieces can also be guided along on a smooth and flat sliding surface by means of the brushes, their feed being effected by the main brushes acting in the feed direction.
  • This main feed is not affected by the fact that occasionally opposed Working brushes, such as the hold-down brushes or the sponge roller brushes, are provided, since the feed forces applied by the main brushes are in any case a multiple of the forces of the sponge brush rollers working in opposite directions.
  • This sliding surface can consist of a polished stainless steel, a smooth, wear-resistant plastic or the like, so that the movement of the textile pieces along this surface is not hindered.
  • the sliding surface can be provided with openings pointing downwards, through which the excess paint or the excess paint material (the paint liquor) can drip off and be collected there.
  • the liquor so discharged can be reintroduced into the liquor tank in the upper area of the device.
  • certain forms of patterns can also be deliberately achieved by physically applying pattern pieces to the surface of the sponge brush roller, which can be done by gluing or, for example, by applying a sponge brush roller over the entire surface a network is maintained, which holds the above items on this.
  • a network has the advantage that the contour that is to be created by the sample appears to be dissolved (smoothed).
  • the sample can consist of a textile, a flexible plastic, but also of a flexible metal material.
  • Another possibility for generating the pattern is that recesses are made in the surface of the sponge roller brushes, for example by milling, which form the pattern contours.
  • the net drawn over the sample pieces and the sponge rollers can also be a textile material, for example a coarse-mesh textile material, the stitches of which can then be found as a pattern on the textile piece to be colored.
  • a plurality of rotating and driven brushes 1 are provided, which apply the dye liquor to the textiles to be processed.
  • the paint liquor is located in a row of receptacles 2, each of which has separate outlets 3 in the form of shaft-like channels or lines, which are directed towards the bristles of the brushes 1 arranged below the container 2.
  • outlets 3 in the form of shaft-like channels or lines, which are directed towards the bristles of the brushes 1 arranged below the container 2.
  • FIG. 1 the perspective representation of the containers 2, the outlets 3 and the brushes 1 is only indicated schematically in FIG. 1.
  • the outlet lines 3 for the paint liquor can be shut off individually by shut-off valves 4, the shut-off valves 4 being arranged in the immediate vicinity of the surfaces of the brushes 1.
  • the outlet lines 3 can also be provided with a bypass 5, which supplies the paint liquor past the valves 4 past a second row of outlet lines 6 with valves 7 and, via these, to a second row of brushes 8.
  • This type of direction of movement is also represented in FIG. 2 by the arrow 11.
  • the pieces of textile to be processed are thus entered into the device above the conveyor belt 9 on the right in FIGS. 1 and 2 and processed in the manner described by the rotating brushes 1 resting on this conveyor belt under tension.
  • the dye liquor is fed to the textile pieces via the feed chutes 3 and the brushes 1 and, furthermore, their surface is machined due to the prestressing.
  • the conveyor belt 9 is provided in the area of its upper run in a manner known per se with small support rollers 12, so that the pre-tension is maintained over the entire length of the conveyor belt.
  • the conveyor belt 9 consists of an elastic material provided with openings so that the excess liquor of paint can get down into a receiving trough 13 arranged below the conveyor belt 9.
  • a deflection device in the form of a guide plate 14 which the textile pieces conveyed out of the first brush set 1 in the direction of arrow 15 and processed on one side, the second lower brush set with the brushes 8 feeds.
  • the textile pieces are deflected in the direction of arrow 16 by the guide plate 14. They then run through the second lower brush set in the direction of arrows 17 and are conveyed out at 18.
  • the structure of the lower conveyor belt 19, which is guided over rollers 20 and whose upper run is also held against the brushes 8 by support rollers 12, corresponds to that of the upper conveyor belt 9.
  • the individual receptacles 2 are in the area of their container-side outputs with a steam line 21, so that via the outlet line 3 for the liquor steam can also be supplied to brushes 1 and 8.
  • a compressed air line 22 can be arranged in the containers 2, which has outlet openings facing the interior of the individual containers, so that air is blown into the containers in order to swirl the paint liquor and keep it moving.
  • At least one steam nozzle 23 can be provided in the area of the guide plate 14, so that the back of the textile pieces to be treated is also moistened by the steam during the deflection.
  • the distance between the brush axes and the conveyor belts 9 and 19 can be adjustable, so that the pretension between the conveyor belt surface and the bristles can be changed.
  • the main brushes 1 which are used essentially for processing are arranged next to one another on common shafts 26 and also one behind the other.
  • Small intermediate brushes 24 which may not be used for the application of paint, but only for the wearing treatment of the surfaces of the textiles, can be arranged in the spaces that result. In addition, as described above, they can act as hold-downs for the textiles in order to prevent the textiles to be treated from being pulled up or displaced.
  • additional intermediate brushes 25 can be provided which rotate in the opposite direction to the main brushes 1 which determine the conveying direction and thus produce folds which are subject to particular wear and tear from the brushes.
  • Fig. 3 shows a schematic representation of the brush sets 1 and 8, and their common drive 29 and 30, which can be a chain drive, for example.
  • the intermediate brushes 25 shown here and rotating in the opposite direction are actuated by appropriate guidance of the common drive.
  • the forces which can be transmitted to the textiles by the intermediate brushes 25 moving in the opposite direction can amount to approximately 25% of the total forces acting on the textiles.
  • the speed of the drive can be infinitely variable, so that the brushes 1 of the upper brush set can rotate at a different speed than the brushes 8 of the lower brush set.
  • Fig. 4 shows a schematic representation of the small intermediate brushes 24 which act as hold-down devices (cf. also FIG. 2) for the upper and lower brush set of the device.
  • These intermediate brushes 24 can also be provided with drives 31 and 32 designed as chain drives, the chain drives here also being controllable.
  • the intermediate brushes 24 and 25 (see FIG. 2), including their drives, can be detachably inserted as a structural unit between the main brushes 1.
  • an additional device 40 is arranged between two rotating main brushes 8, with which a dyeing process as such can be further refined and thus improved compared to that according to the above-mentioned embodiments.
  • the body of the additional device 40 has schematically indicated steam nozzles 41 which, as shown, can be directed against at least one of the rotating brushes 8 and which can be acted upon by a steam line 42, for example by a steam heating line.
  • the line 42 is also connected to the base body of the additional device 40.
  • the steam nozzles 41 can alternatively or simultaneously be subjected to wet steam via a further line 43.
  • the steam nozzles are adjustable according to the requirements.
  • paint nozzles 44 are provided, which can be connected to a compressed air line (not shown) and / or can be acted upon by the steam lines 42 and 43.
  • the paint supply is located in a container, not shown, to which the compressed air line can be guided in the form of a Venturi tube, so that the paint can be supplied to the paint nozzles 44 in atomized form.
  • the paint particles emerge finely distributed from the paint nozzles 44 so that they can be gripped by the brushes 8 and 24 in the manner described and introduced into the fabric 45.
  • the known methods also have a dye consumption which is up to 50 times higher, as well as a high consumption of chemicals, bleaching agents and abrasives, the latter not being able to be rinsed out of the fabric without residues despite intensive rinsing of 70 l and more per part.
  • the fabric is dyed step by step and in layers only up to the desired color level and since this does not mean that a basic dyeing has to be washed out again, this environmentally harmful operation is completely eliminated.
  • the brush technique on which the invention is based achieves a significantly higher degree of softness, so that the fabric becomes comparatively more fluid.
  • FIG. 6 shows a perspective view of a modified embodiment in which the hold-down rollers 24 (cf. FIG. 2) are not designed as bristle brush rollers but as sponge rollers.
  • the hold-down rollers 24 are not designed as bristle brush rollers but as sponge rollers.
  • These consist of a tubular shaped piece 51, which is attached to the associated shaft 50 by gluing or the like.
  • the tubular sponge shaped piece 51 can sit on the shaft 50 under pre-tension.
  • the sponge roller 52 thus formed serves primarily not to wear the textile pieces to be treated, but rather to apply paint in the manner described above, the textile pieces being squeezed and crumpled by the sponge rollers 52, so that a stronger ink application occurs in the fold area thus produced .
  • the shaft 50 can be moved more or less close to the conveyor belt 9 or to the upstream and downstream brush rollers 1 upwards, downwards and to the side in order to influence the identity of the paint application and possibly the subsequent resolution of the contour in the desired manner . Corresponding adjustment devices for the shaft 50 are provided for this.
  • the tubular foam covering 51 can also be covered by a net 53 and fastened on the shaft 50, the net, as shown, can be of large mesh so that the individual meshes 54 are on the surface map the sponge roller 52.
  • the net 53 can be guided around the sponge roller 52 in the direction of the arrows 55, the free ends 56 of the net 53 overlapping.
  • certain preformed patterns 57 can be physically applied, which can be done by gluing or by the fact that the net 53 simultaneously holds these patterns. In the latter case, the pattern of the meshes 54 would be found on the sponge roller 52 in addition to the pattern 57.
  • the pattern 57 can consist of a textile, a flexible plastic or also of a flexible metal material.
