Definitions

  • the subject of this invention is a method of and apparatus for dyeing yarn and particularly for the continuous dyeing of yam.
  • the method of dyeing yam usually performed heretofore has been a batch dyeing method, i.e. a package containing a considerable length of yam is immersed in a vat containing a mixture of dyes in proportions to give the required dye shade to the yam on the package.
  • the batch process presents several important difficulties and drawbacks. For example a considerable time is usually required for the dye liquid to penetrate to the innermost layers of the yam on the package and further time is required for the dyeing reaction to be completed. As dye pigment is continually removed from the dye liquid on its passage through the yam _package the dye liquid becomes progressively weaker, i.e.
  • Another trouble is that often the yam shrinks on the package and this causes the inner layers to be compressed giving rise to difficulties in unwinding the package as well as hindering dye penetration.
  • the wet packages must be dried thoroughly and this requires a considerable amount of time and space.
  • a method of continuously dyeing a yam by applying a dye liquid to the yam while the yarn is in motion is characterized by applying at least one dye liquid to the yam in a series of discrete quanta, the volume of each quantum and the number of quanta applied per unit length of the yam being predetermined to provide a dyed yarn of the desired visual appearance.
  • a nonprimary colour several different dye liquids may be applied simultaneously in discrete quanta against the moving yam, the volume of each quantum of each dye liquid and the number of quanta of each dye liquid applied per unit length of the yam being predetermined to provide that the dyed yam is of the desired colour and shade.
  • one of the dye liquids may be a diluent such as water.
  • the colour and shade of the dyed yam may be automatically controlled by passing the dyed yam through a colour analyser, e.g. a spectrophotometer, which can detect variations in the spectrum of the colour of the dyed yam from that desired, the analyser being operative on occurrence of any undesired change in the spectrum to detect the change and send a correcting signal arranged to initiate a change in the volume of each quantum and/or the number of quanta applied per unit length of one or more of the dye liquids being applied whereby to restore the desired spectrum.
  • a colour analyser e.g. a spectrophotometer
  • the quanta of dye liquids may be brought together on the yam itself or may be brought together in a continuous mixing operation at the yam.
  • Apparatus for performing the method comprises yam feed means for feeding yam to be dyed forwardly, means for holding the dye liquid to be applied to the yam and means for applying dye liquid to the yarn and is characterized in that the means for applying the dye liquid to the yarn incorporates means arranged to feed the dye liquid to the yarn in individual quanta and means is provided for varying the volume of each quantum and for varying the rate at which the quanta are applied to the yam.
  • Means operatively linked to the yarn feed means may be arranged to control the volume of each quantum of dye liquid applied to the yarn and/or the time interval between which successive quanta are applied to the yam in accordance with the rate at which the yarn is being fed forwardly by the yam feed means.
  • the dye applying means may incorporate valve means controlled by individual pulses of a pulsed signal the frequency of the pulses of which is controllable.
  • each dye applying device may be arranged angularly spaced from one another around the yam, each dye applying device having its own control means capable of controlling the volume of each quantum of dye liquid and the frequency with which the quanta are applied.
  • Each dye applying means may incorporate a pump arranged to feed dye liquid in pulses to a dye-applying device.
  • a pump arranged to feed dye liquid in pulses to a dye-applying device.
  • One type of pump which is suitable is a pump of the type known as a peristaltic pump in which a flexible tube is stroked successively by pressure devices each of which in succession comes against the tube, flattens it, moves some distance forward and then releases the tube so that quanta of liquid in the tube are trapped and propelled forwardly in pulses.
  • Pumps of the types described may be connected to synchronous electric motors fed from sources of controllable frequency.
  • pumps of the diaphragm type may be used, the diaphragms being connected to vibrator type mechanism arranged to be fed from sources of pulsed electric current.
  • FIG. 1 illustrates apparatus in its most basic form
  • Fig. 2 indicates an apparatus employing pumps each of which is connected to an individual synchronous motor
  • Fig. 3 shows an apparatus providing automatic colour control by means of a spectrophotometer.
  • Fig. 1 denotes a yam to be dyed
  • 2, 3 and 4 denote dye liquid projecting devices arranged to project dye liquid in discrete quanta against the yam 1
  • the dye liquid projecting devices being connected to dye supply tanks 5, 6 and 7 respectrvely.
  • the dye projecting devices are connected to variable frequency sources 8, 9 and 10 respectively.
  • the dye liquid projecting devices incorporate pumps 11, 12 and 13 discharging into a chamber 14 through which the yam 1 is arranged to pass, the dyes being mixed at the same instant as they are brought into contact with the yam 1.
  • the pumps 1 1, 1 2 and 13 are connected to synchronous motors arranged to be controlled by the variable frequency sources 8, 9 and 10.
  • a spectrophotometer provides a spectrum 16 of the colour of the yam 1 after it is dyed.
  • Light sensitive devices 17, 18 and 19 are arranged to detect the respective light values of different portions of the spectrum 16 and to issue corresponding control signals which are fed to the variable frequency sources 8, 9 and 10 as frequency control signals.
  • 20 denotes means for feeding forwardly the yam 1.
  • the dye liquid either as a single dye or several dyes is applied as a series of quanta to the yam, the volume of each quantum and the rate at which the quanta are applied being adjusted to provide a quantity of dye on the yam such as to provide the required shade and colour. Changes may be made instantly to the colour by adjustment of the quantum volume or quantum frequency of any or all of the dyes applied. Any undesired change in the shade or colour of the yam immediately causes a change in the spectrum 16. This causes an immediate response in the appropriate light sensitive device 17 and/or 18 and/or 19 so that a control signal is issued to the appropriate variable frequency source or sources 9.
  • the apparatus and method have the advantage that no excess dye is used.
  • the frequency of quantum deposition may be such that each quantum overlaps the previous quantum deposited or follows immediately on the previous quantum or a gap is left between successive quanta, the gap being small enough to allow dye penetration along the yam to fill the gap. Mottled effects may be achieved by arranging the quanta frequency such that an appreciable gap is left between successive quanta where no dye is deposited on the yam.
  • the portion of the device actually discharging dye liquid to the yam may be arranged to contain a minimum quantity of dye liquid so that changes of colour may be effected by switching the dispensing device or devices to different supply tanks containing different dye liquids. Changes to different colours containing the same constituent dyes but mixed in different proportions may be effected immediately by altering the settings of the apparatus controlling the volume of each quantum of dye liquid and the rate at which the quanta are applied to the yam.
  • the present method may be applied to the performance of the method of dyeing which is the subject of the prior patent application EP 0 079 213.
