Definitions

  • This invention applies to the textile finishing sector and specifically describes a new procedure for the dyeing or discoloring (required, for example, to attain an aging effect) of garments and more generically of fabrics and yarns.
  • the current procedure available to unevenly dye and/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.
  • the most immediate disadvantage originates from the fact that it is necessary to preventively impregnate the rough material particles, which complicates and slows down operations, besides exposing operators to the fumes of the dyeing or discoloring fluid substance or to accidental contacts.
  • the new procedure for the uneven dying/discoloring of garments and more generically of fabrics and yams, referred to in this invention, has the essential characteristics specified in the first claim.
  • the material to be unevenly dyed/discolored is inserted directly into a machine with revolving drum so that it can be preliminarily evenly dyed with known methods and repeated cycles (that shall described in the pages that follow), if required.
  • the dye is disposed of and the material centrifuged. If the material does not require a preliminary dyeing or has been already dyed before its insertion into the machine, it is only necessary to centrifuge it by adding the required amount of water. At this point, it is necessary to insert into the drum the material, which still has a very high level of humidity, together with the containers that hold the chemical dyeing or discoloring substance, preferably in powder.
  • the containers which are made in a material suitable to withstand the chemical aggression and the temperature typical of the treatment, i.e. usually plastic like ordinary polypropylene or similar polymeric materials, have small holes to allow the gradual release of the substance and its distribution on the material that needs to be bleached/dyed.
  • one of these containers can be constituted by a simple cylindrical container (1) sealed on the top (2) by a screwed cap (3).
  • the cap as Figure 2 clearly shows, has several small holes (4) to allow the release of the powder.
  • the size, number and arrangement of holes vary according to the desired result, as explained in the sections that follow.
  • the opening (2) can be fitted with a diaphragm (5), which snap in place at a greater depth as compared to the cap (3).
  • the opening and the cap are placed at a specific distance in order to form a hollow space (6 of Figure 3).
  • the diaphragm (5) also has holes, though not visible in the figures, because it is used to obstruct the flow of the powder so that it can be released gradually and progressively, depending on the desired result.
  • the powder flow is schematically illustrated and marked as P in Figure 3.
  • this phase which can have a varying duration depending on circumstances (type of material, type of substance, desired effect, etc.), it is necessary to add water to the drum in order to neutralize the chemical substance and fix the treated material.
  • the empty containers can be left inside the machine during this final phase and removed together with the dyed/discolored material. However, if they still contain a small amount of substance, it is advisable to preventively remove them, because the impregnation phase would cause the release of the residual chemical substance and lead to a consistent distribution of the color. All the containers have to be reloaded before the next cycle.
  • the containers holding the chemical substance are prepared outside the machine in conditions that do not require total dryness or the availability of other machines or baths.
  • the workers in charge of this operation are not exposed to fumes and do not risk coming into contact with chemically aggressive fluids, because the powder chemical substance is handled in dry conditions and maintained segregated and inert until its introduction into the machine after the loading of the containers.
  • the above description is obviously very generic as the procedure can be adapted and changed according to requirements; for example, as described above, for manufacturing requirements. Changes and adaptations can be easily implemented using the traditional methods typically employed in this field.
  • the preferred dyeing/discoloring agent is powder, because it allows to distribute spots of color on the fabric.
  • the use of liquid substances offers equally interesting effects, i.e. the distribution of stains and veneering, caused by the application of small drops of liquid and by its sagging.
  • This procedure enables therefore to use oxidizing or reducing agents to bleach/discolor a dyed fabric.
  • Other applications may require the use dyeing pigments with different properties and concentrations (it is also possible to add different substances to the individual containers), along with suitable fixing agents.
  • the treatment shall consist in an uneven dyeing of the material, regardless of whether it had already been dyed or not.
  • These types of effect usually require an additional phase to fix the dye on the textile fibers, which is achieved through the introduction and generation of steam inside the drum. It is also possible to use binding resins (for metal, shot or color effects). Even in this case, an additional drying phase is required to fix the dye on the fabric before the final washing.
  • the preliminary dyeing when used, may include two different phases and dyes: an initial dying with a dye resistant to the chemical bleaching substance that will be subsequently used and a subsequent dyeing phase with a more intense yet less resistant dye.
  • the final result consists in a series of stains/streaks of the second color on the first background color.
  • the shape of the containers, the number of containers introduced into the drum and the distribution of the holes can be selected in function of the desired effect.
  • the procedure does not require the compulsory use of a machine with a revolving drum, as it can be easily employed with similar machines, for example with vibration machines.
