Definitions

  • the invention relates to the machine used to bleach and change the color of the wools and the fabric fibers located on the raw leather.
  • the invention relates in particular to the bleaching and color changing machine, which enables said wools and fibers to be bleached at a lower cost with maximum efficiency.
  • the methods employed predominantly for the bleaching processes have included the steam-bleaching method and the bleaching method with peroxide derivatives.
  • the bleaching is achieved by the oxidation and disintegration of the pigment molecules as a result of the peroxides releasing oxygen at high pH values.
  • the bleaching applied with peroxides which is a difficult to control method, is employed to bleach the cellulosic fibers.
  • due to their requirement for high pH and their denaturing effects on the proteinic fibers it is not possible to use said processes in bleaching the wool fibers in an efficient manner.
  • the chemical substances applied to the fiber exhibit the bleaching effect upon encountering the steam.
  • this method may only be used in bleaching the wools and fibers, which are dyed with dispersed dyes.
  • Said process is employed in cases where the product is to be put on the market in a white color. Since the product is released to the market in white color, it is subjected to a very good bleaching process. Such a better bleaching process is achieved via combined bleaching by using a more effective bleaching agent and employing more severe bleaching time and conditions.
  • a dyeing or bleaching mechanism which comprises the mobile spool holder shafts for the threads wound around the spools or similar packages, said holder shafts being also removable for the water filtering and drying processes, and a dyeing tank having a circular cross-section suitable for the inlet of a single circular load, being able to run with a lower amount of liquid and also being able to be used for partial capacities according to a fixed impregnation ratio.”
  • the fabric which is subjected to a chemical reaction, is dyed and bleached inside the dyeing tank.
  • the proposed invention is a machine, which enables the color lightening and bleaching processes performed either as a necessity of production or for decorative purposes on the indigo carmen dyed fabric, also called denim in the textile sector, and on the cloths produced from said fabric, to be carried out in a rapid, economic and environment-friendly manner.
  • Our machine allows the use also in the acid- and reactive-dyed products.
  • the machine comprises the cylindrical inner and outer cabin, which are arranged one within the other, ozone generator and the control panel. Located on the outer cabin are the ozone gas inlet, air inlet and outlet holes, and the filling and discharge cover.
  • the inner cabin is made with a perforated structure, and the part of the shaft that surrounds the cabin which passes through the outer cabin is manufactured in a way that it will not leak the pressurized ozone. Also, there are the vanes inside the inner cabin.”
  • the bleaching process may not be used in bleaching the cotton structure on the raw leather.
  • the object of the invention is to enable the wools and the fibers to be bleached by means of electrical energy, without the need for steam energy.
  • Another object of the invention is to provide a much more efficient bleaching.
  • Another object of the invention is to avoid the health problems encountered both in the workers and the users as a result of the chemicals used for bleaching said wools and fibers.
  • Another object of the invention is to minimize the costs, owing to the fact that bleaching process is performed without the use of chemicals and the steam.
  • Another object of the invention is to provide the whitening for all kinds of fabric owing to the bleaching process performed with UV rays.
  • Another object of the invention is to enable also the wools dyed with non-dispersed dyes to be clearly whitened owing to the application of UV.
  • Another object of the invention is to enable the recovery of an enormous economical value and to make it possible to obtain the effects, which have not been possible so far in the textile and leather sectors.
  • Said UV bleaching machine consists of the protective layer (1), height adjustment apparatus (2), conveyor and/or fixed platform (3), reflector (4) and UV lamp (5).
  • UV which is normally used at a distance of e.g. 1 m
  • the UV (bronzer) is provided in a more intensive manner by way of reflection with the aid of the reflector (4) from a close distance, it enables a rapid whitening or lightening in the shades of the colors applied with different dyeing processes.
  • Said protective layer (1) is positioned at the lower and/or upper parts of the machine, in order to protect the employees from the hazardous effects of the UV radiation emitted from said UV bleaching machine.
  • the height adjustment apparatus (2) is positioned below said top protective layer (1), in order to adjust the distance of UV light to the application surface. Owing to said height adjustment apparatus (2), it is possible to carry out applications at different heights. Different effects and results may be obtained by virtue of the application at different heights. Consequently, it becomes possible to carry out a more flexible and diversified production.
  • the reflectors (4) positioned below said height adjustment apparatus (2) are used to direct the UV light onto the application surface in a homogeneous manner.
  • the reflectors (4) may be used in a state coated with different reflective materials and bent according to different shapes, in an effort to benefit from the UV light to the maximum possible extent.
  • Conveyor (3) is used as the carrying means for a continuous feed of the surface, where the application is to be made, into the machine, according to the industrial-scale production.
  • Said conveyor (3) is used as the fixed platform (3) in the trial machines and/or for the trials per lot.
  • the UV lamp (5) positioned as the lamp that provides the UV radiation, is connected onto said conveyor and/or fixed platform (3).
  • said UV lamp (5) may be arranged as a single unit or a plurality of units placed side by side depending on the machine size, the width of the application and the desired production capacity, and the units may be used in a single array or as many rows of arrays arranged successively, depending on the desired width of application and the desired production capacity.
  • the raw leather on which the wool desired to be bleached is located is placed on said conveyor and/or fixed platform (3) such that the wool will be at the top.
  • the height adjustment is made by means of the height adjustment apparatus (2), depending on the amount of wool, duration of treatment and the desired effect.
  • the UV rays emitted from the UV lamp (5) are reflected by the reflectors (4) to hit said surface. Said wools are bleached by means of the influence of the UV rays on the wool.
  • the effects like color lightening, etc. may be obtained in the dyed wools to which formic acid and zinc formaldehyde sulfoxylate are applied.
