Definitions

  • This invention refers to an apparatus for use in processing fabrics, for example for carrying out a process to age and bleach fabrics, especially denim, which is the subject of another patent application by the same applicant.
  • the fabric to be treated is repeatedly tumbled, together with a pre-established amount of sand or other granular material impregnated with a bleaching agent, until the desired degree of aging or bleaching of the fabric is achieved.
  • Other known processes entail the use of pieces of pumice or the like.
  • an object of this invention is to provide an apparatus for carrying out the above or other chemical processes on fabric, that is of simple construction, makes it possible to avoid the abovementioned drawbacks, namely that permits even distribution of the granular material on the fabric to be processed, avoiding the formation of build-up areas in the drum, and at the same time prevents the steam or gases from the chemical substance from escaping, whether during processing or during loading and unloading of the fabric, when the machine is open.
  • a further object of this invention is to provide and apparatus of the type described above that furthermore provides for automatic separation of the granular material or pieces from the fabric and for unloading of the fabric at the end of each work cycle, particularly in large apparatus.
  • a fabric processing apparatus wherein the fabric is placed in a rotating drum together with a substance in grains or pieces mixed with a bleaching agent or other chemical processing substance, characterized by the fact that the drum comprises an unperforated wall on the inside of which are provided fins for tumbling the fabric and the grain or piece material, that extend parallel to the axis of rotation of the drum or form a certain angle with it, said fins consisting of shaped elements protruding towards the inside of the drum and having a convex cross-section, with a wide angle, greater than 90°, at the vertex, and with the edges of the fins merging with the inside surface of the drum, and by the fact that means are provided for sucking the steam and/or gases developed by the chemical processing substance inside the rotating drum.
  • the apparatus comprises a sealed rotating drum 10, defining a closed space, supported by means of a shaft 11 driven by an electric motor 12.
  • the drum 10 has an unperforated surface and can be loaded by means of a hatch 13.
  • a structure 14, shown schematically, contains and supports the rotating drum 10.
  • the inner surface of the drum 10 is provided with shaped fins 15 in angularly spaced positions, that extend longitudinally and parallel to or forming an angle with the drum's axis of rotation. These fins serve to tumble the textile fabric inside the drum and to bring about a good distribution of the granular material or pieces impregnated with the chemical processing substance, without creating areas or points of accumulation or stagnation of the aforesaid material.
  • the fins 15 protrude towards the inside of the drum and are so shaped that their profile has a wide angle, greater than 90°, at the vertex, between about 120° and 150° for example, in this manner they give the inside of the drum an undulated shaped configuration that aids tumbling of the fabric while at the same time allowing smooth movement of the processing material.
  • the fins 15 are triangular in section with flat sides 16 that form an angle of abaout 135° at the vertex; the fins 15 are smoothly joined by a wide area at their base to the inner surface of the drum.
  • the apparatus is provided with sucking means to remove the steam or gases of the bleaching agent or other chemical processing substance that form inside the drum and might tend to escape when the apparatus is opened.
  • the sucking means can include an aspirator 17 connected to the inside of the drum by means of a duct 18, a rotary seal 19 and a duct 20 in the shaft 11 of the machine which in this case takes the form of a tubular shaft.
  • an aspiration duct 21 that opens into a hollow space 22 formed by the structure of the apparatus around the rotating drum 10.
  • the apparatus will obviously be provided with all necessary automatic mechanisms to ensure constant operation of the sucking system when the apparatus is running, or to activate it when the apparatus is opened.
  • a second safety door may be provided on the structure 14 to coincide with the drum hatch 13.
  • the drum 10 is circular in shape and is supported by a single tubular shaft.
  • Figures 4 and 5 show only the drum of a second embodiment of the apparatus according to the invention.
  • the drum 25 is polygonal in section, for example hexagonal or octagonal, and is rotably supported by means of two hollow shafts 26 connected by means of rotary seals 27 to a sucking system 28.
  • Fins 15 are provided at each vertex or at some vertices of the polygonal section, while a protective grille 29 or net or check valve is provided at the inner ends of the tubular shafts 11 and 26 of the examples described to prevent excape of the granular processing material or pieces.
  • the drum 10 and 25 of the apparatus can have a cross section of any other suitable shape.
  • the apparatus in figures 1 and 5 is envisaged for manual loading and therefore the size of the drum 10 or 25 is limited. If it is desirable to work with larger drums, for larger machines or apparatus, the apparatus shown in figures 6 and 7, which is envisaged for automatic unloading, can be used.
  • the apparatus still comprises an unperforated drum 30, similar to the previous drums, rotating inside a protective structure that has in its lower part an unloading chute 32, beneath which can be placed a bin (not shown) to collect the granular material or the processed fabric.
  • the rotating drum 30 of the apparatus is provided with an unloading hatch 13 on the front wall, with aspiration in the rear wall and an unloading opening closed by a hatch 33 at a pre-­established point in its peripheral surface, it being possible to remove said unloading hatch in any manner, for example by sliding it in an axial direction, from one side of the apparatus.
  • the hatch 33 is therefore mounted on guides 34 on the outer surface of the drum. Since it is advantageous, before unloading the processed fabric, to separate the fabric from the granular material or pieces still partially impregnated with the chemical processing substance, a perforated grille 35, sliding axially in the aforementioned guides 34, is provided on the outside of the hatch 33 and can be removed separately or independently from it.
