Definitions

  • the present invention relates to an apparatus for textiles treatment.
  • the apparatus being the object of the invention can be used for high-hydrodynamic-efficiency water treatment of fabrics or textiles in general or also as a tigering unit for velvets and the like, and as a pre-washing and washing unit for textiles during the pre-treatment and fixing steps, after dyeing or printing.
  • the water thus thrown along the useful length of the rotor impinges on a fabric in transit on a path at least partly surrounding the rotor itself.
  • shaping of the rotor has proved to be of the greatest importance for optimisation of the hydrodynamic efficiency of the fluid exiting the rotor and it too appeared to be improvable under different points of view.
  • the present invention aims at solving all the drawbacks highlighted above.
  • a first aim of the invention is to make available an improved apparatus for treating textiles which is capable of optimising the operating parameters with particular attention to the number of revolutions of the rotor and the flow rate of the admitted fluid, depending on the working operations and the basic weight of the fabrics being treated.
  • Another aim of the invention is also to optimise the efficiency in cleaning the liquid containing impurities as well as improving pulling of the fabric within the apparatus.
  • an apparatus for textiles treatment in accordance with the invention has been generally identified by reference numeral 1.
  • This apparatus will be suitable for use for different types of working operations during both the preparation step and the finishing step, after the high-quality finishing operations, as a tigering unit for pile textiles such as smooth or cord velvets and the like.
  • the apparatus in reference will be also usable with different treatment fluids such as cold or hot water containing possible chemical products suitable for the treatments in progress (soaps, detergents, sequestering agents, etc.).
  • treatment fluids such as cold or hot water containing possible chemical products suitable for the treatments in progress (soaps, detergents, sequestering agents, etc.).
  • solvents could be used, should these treatment methods be required.
  • the apparatus will be suitable for defining continuous and open-width washing lines for textiles in which a fabric "T" will be introduced into the apparatus at an inlet station "I” and, after being submitted to treatment, will come out of the apparatus through an outlet station "U".
  • the apparatus for treating textiles will be generally provided with a supporting frame 2 capable of internally defining at least one work environment (see Fig. 1 ).
  • At least one rotor 4 will be present, which extends longitudinally along an axis 17 and is movable in rotation around the same axis.
  • the apparatus will also comprise feeding means 5 for supplying said rotor 4 with a treatment fluid.
  • feeding means 5 for supplying said rotor 4 with a treatment fluid.
  • at least one pump 8 will be present, as well as one or more ducts 9 adapted to take the fluid into said rotor in varying flow rates and at defined pressures.
  • the rotor will be set in motion through suitable actuating means 6 capable of selectively driving it in rotation, depending on the desired speed on the rotor itself.
  • said means 6 can be defined by at least one direct-current motor 10 running at varying revolutions or an inverter capable of sending the rotor, through a suitable transmission, the required power for setting it in rotation at a controlled and obviously varying speed.
  • a guide assembly 11 is then present and is disposed around the rotor in possibly modifiable configurations depending on current working requirements.
  • the guide assembly 11 is adapted to support, the fabric "T" to be worked inside the work environment 3 and at least partly around said rotor 4.
  • the guide assembly 11 comprises a plurality of transport cylinders 12 and transmission cylinders 13 so that fabric "T" is guided along its path within the work environment 3 starting from the inlet station "I” and towards the outlet station "U".
  • the transport cylinders 12 are cylinders provided with reels and have a structure defined by rest surfaces 12a for said fabric "T" alternated with free treatment regions 14 which the fabric can cross, said fabric being impinged on and passed through by the operating fluid.
  • a dragging system will be present which is adapted to ensure correct pulling of the fabric when in engagement with the guide assembly 11 and also adapted to allow dragging of the fabric itself without creating jamming or the like at the outlet station "U".
  • At least one electric motor 22 (a brushless motor) will be present which is adapted to operate a predetermined number of said transport cylinders 12 and/or transmission cylinders 13; in particular motor 22 will be able to control at least one cylinder and at most three cylinders.
  • the apparatus is also provided with a management unit 7 adapted to correlate an operating parameter of the feeding means 5 with an operating parameter of the actuating means 6.
  • programming of the management unit 7 will be carried out in order to associate each operating parameter of the feeding means 6, with a corresponding operating parameter of the actuating means 5; in other words, setting of a parameter of the feeding means, and/or the actuating means involves automatic setting of the corresponding parameter of the actuating means or the feeding means.
  • the management unit 7 can be defined by a PLC or also by a programmable CPU in such a manner that an operator can ensure optimal working by, for example, inputting the basic weight of the fabric entering the apparatus.
  • the management unit 7 is able to set the optimal number of revolutions of the rotor and also to set the optimal flow rate of fluid for that fabric.
  • the management unit By inputting a greater or smaller basic weight, the management unit will be able to automatically set greater/smaller flow rates and higher/lower rotation speeds correlated with each other and optimal for the type of treatment to be carried out.
  • controlled parameters could be different.
  • the actuating means 6 it will be possible to control the electric power supply to motor 10, the rotation speed of same or also the power transmitted to rotor 4, as an alternative to the already mentioned rotation speed.
  • the apparatus also comprises at least one and preferably two fluid-collecting vats 15a, 15b placed below rotor 4 and designed to receive the fluid and possible working bottoms such as impurities and fabric waste.
  • the two collecting vats 15a, 125b are placed at the opposite sides of the apparatus and extend longitudinally in a direction substantially parallel to the axis 7 of rotor 4. Then at least one filter 16 is centrally present and it is adapted to enable cleaning of the fluid collected in the vats.
  • Filter 16 too is such positioned that its axis is parallel to the rotor axis 17.
  • a bottom wall 18 having a three-dimensional extension defines the collecting vats 15a, 15b and a raised region 19 for separation between the work environment 3 and filter 16, the latter being therefore housed in a lower portion of the apparatus.
  • At least one conveying duct 20 draws the fluid containing the working bottoms from an outlet opening 21a, 21b of the collecting vat placed to a predetermined height, so as to convey the fluid to filter 16.
  • the water to be cleaned, coming from the textiles washing apparatus, is conveyed into the drum F of the rotary filter by means of a sleeve L.
  • the drum F is formed of a plate pierced with holes enabling the water to be filtered and fall into the recovery tank B while the dirt is retained at the inside thereof.
  • the perforated plate can have holes in the range of 0.7-0.8-1 mm, depending on the type of filtering capability it is wished to be obtained.
  • Rotation of drum F is given by a reduction motor A transmitting movement to a pinion gear C - gear wheel D pair and in this way the dirt is brought to the outside of a propeller E interlocked with the drum F.
  • the propeller E not only performs the function of transporting the dirt but also has the task of stopping the delivery flow of the water to be cleaned.
  • the filtered water contained in vat B and coming out of the exhaust opening N is recirculated by pump H and partly sent to the nozzle-carrying header G.
  • header G The function of header G is to keep drum F clean by means of nozzles; in this way the water is always able to fall into the recovery tank B without the plate holes being clogged, so that any interruption for cleaning operations is made useless.
  • the filter construction material is generally stainless steel so that the filter can be also installed in the open being perfectly resistant to atmospheric agents.
  • the apparatus will be advantageously provided with a system for automatic control of the fluid temperature which is able to signal possible malfunctions, should the temperature be out of a normal-operation range.
  • the apparatus can also have fluid-level sensors to ensure the presence of the optimal amount of fluid within the collecting vats 15a, 15b.
  • the open-width fabric enters the apparatus at an inlet station "I" and is guided along its path around the work environment 3 by the guide assembly 11.
  • the fabric is introduced into the fluid-collecting vat 15a and is suitably wetted to ensure softness and workability of same.
  • the apparatus rotor is set in motion and through the appropriate orifices present on its periphery it ejects a high-speed fluid that impinges on the fabric passing through the work environment 3 particularly at the free treatment regions 14 of the cylinders provided with reels.
  • Passage of the appropriate fluid for instance can aim at forcedly washing the dirt by emulsion, also reaching the fibres' core where the dirt has been absorbed during the spinning or sizing steps.
  • beating cylinders could be present which are adapted to break the lattice defined by the glues (sizes) used during the weaving step.
  • the invention achieves important advantages.
  • the geometric configuration of the collecting vats and the filter positioning allow better cleaning of the operating fluid and also energy recovery at the moment the fluid is sent back to the feeding pump.
  • the washing process is optimised, while control of the transport cylinders through electric motors enables an optimal pulling action on the fabric and correct advancing in the production line to be ensured.
  • the apparatus allows all finishing operations on the fabric adapted to give the latter a more agreeable appearance and enabling it to meet the market requirements, to be carried out thereon with few modifications, which operations will give the fabric aesthetic features (colour, feel, surface appearance) or mechanical-chemical features (shrinkage proofing, crease-proofing, non-inflammability, stain-proofing, water repellence, resistance to atmospheric and biological agents).
  • other possible operations with the present apparatus are directed both to preparation of the fabric to dyeing and to acquisition of other performance and feel properties by the fabric after dyeing (finishing and high-quality finishing operations).
