Definitions

  • the present invention relates to a method for dyeing textile fibers on a jigger, the necessary amount of dye being divided into two or more subsets.
  • the jigger is a machine of the type in which a fabric web, also called a material web, is alternately unwound from the one of two rolls and wound thereon and kept immersed in a dye bath between the two rolls during the passage.
  • the web length immersed in the dye bath is usually of the order of 2 m, and since the speed of the web is of the order of 80-200 m / min. is, a certain point of the web will move during a passage in the dye bath in a period of the order of 1/3 - 3/4 sec. stop.
  • the following passage will compensate for the uneven concentration distribution from the first passage, for example due to the opposite effect of the new exponential dye uptake, but a full adjustment cannot be achieved.
  • a method for dyeing on a jigger is known from German Patent No. 106,342, an attempt being made to eliminate the uneven dyeing by gradually adding the entire dye liquor to the jigger tub during the first passage, but using a small amount of the liquor to cover the bottom rollers may be added in advance.
  • the disadvantages mentioned apply to the jigger as a machine type, regardless of whether it is a machine that cannot be pressurized and therefore can only work at a bath temperature of 100 ° C or whether it is an HT jigger (high-temperature jigger), which is pressurized and can therefore work at higher temperatures.
  • the polyester fiber is the most important, and the optimal color temperature of this fiber is 115 - 135 ° C, depending on whether you are working with low-molecular or high-molecular dyes.
  • dye absorption cannot be controlled by chemical means, and it is therefore common to control dye absorption by gradually increasing the temperature from a range where the absorption is zero, so to speak, to the optimal range. Since the limits of this area are very narrow, it turned out to be necessary to raise the temperature in very small steps.
  • the process is also difficult in that it may be necessary to use different dye groups for the same dyeing, so that a critical temperature range has to be passed for each dye group. Since each jigger passage can take 30-60 minutes, it should be understood that this procedure takes a long time.
  • the present invention provides a method for dyeing on a jigger which ensures uniform dyeing of the web and which does not have the disadvantages of the known methods, i. H. poor economic exploitation of the jigger due to the time-consuming and labor-intensive gradual and slow heating of the dye bath.
  • the method according to the invention is characterized in that the first subset is added to the dyebath while the jigger is at a standstill, during which the dyebath is heated to the temperature range for optimum dye absorption, so that after the jigger is actuated, the remaining subset or remaining subsets of dye ins Dye bath is entered linearly as a function of the amount of fabric that passes through the dye bath, the number of passages of the amount of fabric through the dye bath corresponding to the number of dye subsets and the dye bath having a temperature within the range for optimal dye absorption.
  • the second requirement is only sufficiently correct as long as the color process is far from the eventual equilibrium state, but it is precisely in this initial phase that the risk of uneven color absorption is greatest. As one approaches the eventual equilibrium state, the rate of absorption slows down and the risk of uneven ink absorption is reduced.
  • the total amount of dye is M.
  • a subset thereof M 1 is added before the start of the process and the dye bath thus contains the amount of dye
  • the web takes a dye menu during a passaae
  • FIG. 1 is the high-pressure container
  • 2 is the jigger tub with the dye liquor or the bath 3.
  • the jigger has two rolls 4 and 5, onto which the material web is alternately unwound and wound, as it passes through the bath during such a passage 3 happened around two bottom rollers 6 and 7.
  • the jigger also has a circulation pump 8 for the dye bath, which is connected to the tub 2 by pipes 9 and 10. In the connection of the circulation pump, a metering device 11 for dye is provided.
  • the fabric web moves in the direction shown by the arrows, and a length of the fabric web corresponding to the distance between points A and B via the bottom rollers 7 and 8 is always immersed in the bathroom. This length is of the order of 2 m.
  • the drive devices of the rollers 4 and 5 are not shown, but they are of a well known type and such that the web of fabric moves at a mainly constant speed.
  • auxiliaries such as. B. leveling agents, metal complexing agents and the like, but not dye, added to the bath from the beginning.
  • the jigger is then actuated and the bath is heated to the temperature range that is optimal for color absorption. During this heating period, the fabric web can pass one or more passages through the colorless bath so that there is a temperature equilibrium between the bath and the fabric roll when the desired temperature has been reached.
  • the metering device 11 is opened and a second portion of the dye is metered evenly over the course of the first passage.
  • the jigger does not carry out any passage process of the tissue web. However, it can perform an oscillation while standing still, i. H. that the jigger makes short back and forth movements at one end of the tissue in order to avoid a side weight of the rollers.
