Definitions

  • This invention applies to the textile finishing sector and specifically describes a new procedure for the continuous uneven dyeing or discoloring of fabrics.
  • the current procedure available to unevenly dye or discolor garments in order to attain one of the effects most in demand by current fashion trends and employed in particular for youth garments, consists in preliminarily ironing, softening and drying the garments, in performing a final neutralizing phase and in dying/discoloring the garments.
  • the latter process consists in impregnating granules of rough permeable but highly absorbent material (usually pumice) with a liquid dyeing or discoloring substance, depending on requirements. These granules are inserted, together with the dry garments that have to be treated, into a machine with revolving drum, which is allowed to run dry for a preset time. At the end of the cycle, the granules are disposed of or recycled so that they can be used for subsequent treatments.
  • This procedure is particularly suitable for the uneven dyeing or discoloring of textiles, but cannot be effectively used with fabrics of large sizes or that exceed specific lengths.
  • the aim of this invention is to provide a procedure for the continuous uneven dyeing or discoloring of fabrics.
  • Another aim of this invention is to provide a procedure for the continuous uneven dyeing or discoloring of fabrics, with the characteristics specified above, that enhances the range of aesthetic effects as compared to those that can be attained with traditional discoloring procedures.
  • dyeing or discoloring is carried out using dyes or bleaches in powder, instead of the liquid solutions that are generally employed in traditional dyeing or discoloring treatments.
  • the procedure described in the aforementioned patent application differs from traditional methods because of the fact that the powder dye or bleach is distributed on the fabric while it is fed through a machine designed for this purpose. Before being dyed or discolored, the fabric is immersed into a water bath and pressed in order to attain the percentage of humidity required for the selected aesthetic effect.
  • One of the innovative characteristics of this invention derives from the fact that the procedure foresees the initial distribution of the powder dye/bleach on the fabric and the subsequent application of water (wetting). Water can be nebulized, sprayed, sprayed continuously (rain) or applied in the form of large or small drops. This creates a series of continuous streams that form uneven lines of different sizes, depending on the amount of water applied and on the applications systems used. Technicians must select the distribution system according to the final desired effect.
  • fabric is heated in order to remove all the traces of water.
  • the resulting dyeing or discoloring effects vary according to the system used to distribute water.
  • Water causes the dissolution of the dye or discoloring agent, its distribution on the fabric and the consequent formation of patterns and fancy shapes.
  • Figures 1 and 2 show two possible examples of the effects that can be attained using the procedure described in this invention.
  • the fabric After the application of the dye/discoloring agent and the water, the fabric can be wound up and left in this condition for a few hours to allow it to fully absorb the dye/bleach.
  • composition of the bath used to impregnate the fabric and process conditions vary according to the fibers of the material, as the experts of the field know. With cellulose fibers like cotton, flax, viscose, modal and similar materials, it is necessary to increase the temperature of the bath to 50°C. In this case, the bath should also include a chloride or sodium sulfate saline solution with an absorber to aid the impregnation of the fabric. With reactive dyes it is instead preferable to use baths with a high alkaline pH in order to create the background required to cause the reaction of the dye on the fiber. In this case, it is generally necessary to dampen the fabric with water before heating it, and leave it to rest for 8-10 hours to allow the dye to react with the fiber according to the dye fixing specifications applicable to this type of dye (see the Pad-Batch procedure by way of example).
  • the bath must be heated at 60°C and acidified with sulfuric or formic acid.
  • sulfuric or formic acid For synthetic and acetate fibers, it is necessary to use a slightly acid pH and a temperature of approximately 50°C and include a dispersing agent to allow the fixation of dispersed dye.
  • the dye or discoloring agent is applied to the fabric by means of a special machine that moves the fabric forward at controlled speed.
  • the dye or discoloring agent in powder is distributed onto the fabric by means of a hopper that is placed above the fabric.
  • the powder falls on the damp fabric where it partly dissolves or adheres to it.
  • the degree of consistency of the distribution of the dye or discoloring agent influences the consistency of the final effect.
  • the configuration of the powder distribution system is known, though the system has so far been used for other applications and more specifically for the application of adhesive powder on fabrics designed to be joined at a later stage.
  • the system recommended for this application should comprise a powder distribution system - hopper or equivalent device - and a downstream water distribution system.
  • a feeder is required to continuously feed the fabric to these devices.
  • the fabric can be washed, fixed, softened, dried and thermally fixed using traditional methods.
  • the dyeing and discoloring effects that can be attained vary considerably, depending on the temperature of the water, the degree of compression of the fabric, the amount of powder applied to the fabric and, for discoloring, also on the type of dyes used for the background dye applied to the fabric that has to be discolored (it is possible for example to dye the fabric with a dye resistant to bleaching agents and apply a second layer with a less resistant dye; in this case the discoloring agent attacks the less solid color revealing the more resistant dye). It is also possible to equip the dye distribution machine with special mobile transversal nozzles in order to control the spray of water and apply the exact amount required to dissolve the dye or discoloring agent and form several kinds of patterns by appropriately adjusting the water distribution method and the movement of the nozzles.
  • One of the advantages of the procedure described in this invention lies in the possibility of consistently creating discoloring effects that are highly repeatable and solid.
  • the procedure described can be used for garment fabrics, indoor or outdoor decor fabrics, sports apparel fabrics, household fabrics. It is also useful to notice that the procedure described in this invention offers high outputs along with very low production costs.
  • the procedure described in this invention can also be slightly changed in order to allow the use of pre-dyed polyamide adhesive powder instead of dyeing powder.
  • the dyed powder is introduced into the hopper of the distribution system; it is possible to simultaneously use one or more colors to apply multi-color effects to the fabric.
  • This process differs from the one described above due to the fact that it does not use a dye and does not therefore require the application of water.
  • it is necessary to increase the temperature of the fabric to that of the gluing agent, which can range from 90 to 150°C, depending on the type of glue used.
  • the fabric is conveyed through a pressurized cylinder. Fabric can be protected with a glossy film in order to add glossiness to the polyamide or with a flat film to add flatness to the fabric. In both cases, the film must be removed at the end of the process.
  • One of the initial possible treatment may include the brushing of the fabric in the direction in which it is fed and after the application of water. This can be done with a cylindrical brush that revolves in the same or in the opposite direction as compared to the fabric or with the aid of a fixed brush that moves along the fabric being fed into the machine. This produces an accentuated striping on the fabric. The intensity of the stripes naturally varies according to the conformation and rigidity of the bristles of the brush and to the brushing pressure.
  • a second additional treatment could be sponging. This is done using a spongy surface, which can also be uneven, and rotating it in contact with the moving surface.
  • the cylinder, downstream from the water distribution system, can also be wet independently and be rotated on the fabric with an adjustable pressure.
  • a third potential treatment may involve the use of a preventively dampened fabric in polyester or other material that cannot be dyed with the dyes in use.
  • This fabric is pressed by a pressure roller coated with a dyeing substance. This enables to create the pattern on the polyester fabric while it is still moving. The polyester fabric must then be washed to allow the removal of the residuals of dye before it can be reused.
