Definitions

  • This invention relates to a method for dyeing a bundle of broken fibers, according to the pre-characterizing part of claim 1, and to an apparatus specifically designed for carrying out such method, according to the pre-characterizing part of claim 3.
  • the invention relates to dyeing of synthetic fibres (i.e. acrylic, polyamide, and the like fibers).
  • An apparatus e.g. from FR-A-839 442.
  • This type of product is normally dyed on the same apparatus used for dyeing wool fibers.
  • the latter are subjected to a series of treatments resulting in a product volume intended for accommodation in dyeing tanks of practically standard size, that is having diameters on the order of 400 mm and unit loads per dyeing tank not exceeding 60 to 80 kg with unit packages of 8-12 kg being pressed in the tanks.
  • the pump head is low, and accordingly the capability of the dyeing bath to penetrate the interior of the fiber bundle is relatively moderate, and implies as a consequence that the degree of thickening of the fibers themselves be not excessive, and accordingly also the amount in weight of fibers being treated in each tank be limited within the 60 to 80 kg range.
  • the task of the invention is to overcome the limitations of the prior methods for dyeing a torn bundle of synthetic fibers.
  • Another object of the invention is to enable the dyeing of larger amounts of fiber, for the same operating -conditions.
  • a further object is to provide a more uniform dyeing of the fibers, notwithstanding the presence of appreciably higher unit masses to be dyed.
  • an apparatus for carrying out the method with the features of the characterizing part of claim 3.
  • Figure 1 shows the initial step, known per se, of the method, whereby the synthetic fibers collected into a web 1 are caused to pass through successive roller stations 2, 3 and 4, whereat the web is wound around drive and return rollers.
  • the roller sets of the stations 2, 3 and 4 have progressively increasing speeds, so that the fiber is gradually "stretched" to reach the final zone 5 where further rollers at further progressively increasing speeds cause the bundle to be torn into fiber pieces extending more or less parallel; these fibers, when leaving this first zone of the apparatus, are schematically indicated at 6 and are usually collected in a basket or container 7.
  • the torn fibers 6 are collected inside the container 7 around the core 9, as illustrated by the cited Figure 1A, to form a "toroid" or pack of fibers or doughnuts.
  • a bell 13 is lowered onto the container which seals the assembly to form an autoclave ( Figure 2).
  • the bell 13 is raised and the whole assembly comprising the bundle of treated fibers and disk 10 carrying it is extracted, e.g. with a hoisting means 14 which hooks, e.g. through small chains 15, to the hooks 12 of the cited small chains 11.
  • the hoisting operation ( Figure 4) is carried out while maintaining in the material doughnut the channel 16 created by the core 9.
  • the fiber doughnut is transferred ( Figure 5) into a dyeing tank 17 which is fed through an inlet conduit 18 by a high head pump 19.
  • the return 20 of the pump is connected to a perforated tube 21 the diameter and height whereof are such as to allow the fiber mass to be slipped onto the tube 21 itself, thanks to the channel 16 left within the fiber mass.
  • the doughnut being treated is carried on the base disk 10 whilst the chains 11 are suspended with the hooks 12 from the edge of an inner frame 25 which does not hinder an ample circulation of the dyeing bath.
  • the further step of the cycle provides for the removal of the dyed doughnut, again through the possibility of hoisting the assembly including the base washer and chains with a conventional means ( Figure 7) and the introduction of this dyed doughnut directly into a centrifuge 26 having a concave bottom 27 which arranges for the centrifugal ejection of the water contained in the dyed material.
  • the cycle is terminated ( Figure 8) with a final plucking operation.
  • Several doughnuts are inserted into the inlet end of a line where the fibers are conveyed through successive return rollers 28, being steam heated for the purpose of drying the pack which still contains residual water (the bundle being at this stage open, the water vaporization occurs more easily than with a drying process carried out on the whole toroid or doughnut).
  • stretching rollers 29 and pairs of plucking rollers 30 At the end of the line the thusly dyed and plucked bundle is collected into the container 31.
  • the container has preferably a diameter in the range from 50 to 200 cm.
