Definitions

  • the invention concerns an apparatus and the relative method for dyeing and mercerizing threads or yarns which unwind from one or more feeding beams.
  • the method provides that after a step of warping the yarns, from a plurality of spools to at least one beam, there is a dyeing step, preferably using the pad-batch method, with the yarns being transferred from one beam to another; after which step there follows a step of washing the yarns and then a mercerizing step and a spooling step.
  • threads shall be taken to mean threads or yarns, natural or synthetic, irrespectively.
  • the Italian patent IT-B-1,239,265 discloses a continuous mercerizing method which comprises the following operating steps: pre-washing of the yarns by immersion in at least a tub containing a bath consisting of hot water with added surface-active agents; impregnation in caustic soda by immersion of the yarns in at least a tub containing a bath of heated caustic soda, in order to obtain the mercerization; a stabilization step, with a control of the feedback of the threads in a stabilization and tensioning chamber; a tensioning and stretching step in the afore-said stabilization and tensioning chamber; a step to neutralize the threads with hot washing; and an oven drying step.
  • This method therefore provides that the step of dyeing the threads occurs downstream of the mercerizing step, when the mercerized threads have been spooled.
  • the Applicant has devised and embodied the present invention to overcome this shortcoming and to obtain other advantages which the known method and apparatus did not allow to obtain.
  • the main purpose of the present invention is to achieve an apparatus, and to perfect a method, for mercerizing and dyeing threads, which is reliable and guarantees a uniform dyeing of all the threads.
  • Another purpose of the invention is to optimize conventional methods and apparatuses, so as to reduce the production cycle to a minimum, thus making it more economical, through a smaller number of passes or handling of the material worked.
  • the apparatus comprises first winding means on which a plurality of threads to be dyed and mercerized are wound, dyeing means able to dye this plurality of threads and mercerizing means able to mercerize this plurality of threads and arranged downstream of the afore-said dyeing means.
  • the dyeing means are able to dye the whole plurality of threads in a single dyeing step.
  • Second winding means are positioned between the dyeing means and the mercerizing means to wind the plurality of threads after the dyeing step.
  • washing means there are washing means.
  • first and second winding means comprise beams on which a standardized number of threads, for example 960, are able to be wound.
  • All the threads of a beam are subjected together to at least the dyeing step, and advantageously also the washing and mercerizing steps.
  • an apparatus 10 comprises a first winding beam 11, for example about 2 m wide, onto which a plurality of threads 12 to be treated are wound.
  • This plurality advantageously comprises 960 threads, adjacent and parallel to each other, the length of which depends on their title, which can vary for example from NE20A2 to NE100A2 for cotton threads, and is such that the overall weight of the beam 11 is substantially constant.
  • a dyeing device 15 Downstream of the first winding beam 11 there is a dyeing device 15, or padding, using the pad-batch technique, which comprises a dyeing bath 16, in which the threads 12 are able to be immersed continuously and all together, a series of guide rollers 17 and a squeezing calender 18 with two rollers.
  • the apparatus 10 also comprises a second winding beam 19, to collect the threads, arranged downstream of the dyeing device 15 and on which the plurality of threads 12 are able to be wound after the dyeing treatment.
  • the threads 12 After being dyed, the threads 12 are able to be subjected, all together, to a washing step, in a corresponding washing device 21 (Fig. 3), of a conventional type, before being rewound, still all together, on a third winding beam 22.
  • the threads 12, after being washed, are able to be subjected all together to a mercerizing step, in a corresponding mercerizing device 23, also of a conventional type, before being rewound on a plurality of beamlets 25.
  • the 960 threads 12 are divided into twenty four beamlets 25 of forty threads 12 each.
  • the threads 12 are able to be wound in a plurality of spools 26, so that they are ready for the knitting and spinning steps.
  • the method according to the present invention therefore comprises the following steps: a preliminary warping step 30 (Fig. 5), from spools, of a conventional type and not shown in the drawings, to the first beam 11; a dyeing step 31, by means of the dyeing device 15, from the first beam 11 to the second beam 19; a washing step 32, by means of the washing device 21, from the second beam 19 to the third beam 22; a mercerizing step, by means of the mercerizing device 23, from the third beam 22 to the beamlets 25; a spooling step 34, from the beamlets 25 to the spools 26.
