Definitions

  • the invention relates to a method (according to the preamble of claim 1) and a device (according to the preamble of claim 7) for dyeing tubular goods with reactive dyes.
  • Cotton articles can advantageously be dyed with reactive dyes using the cold residence process. This procedure is successfully used for woven articles and cut knitted fabrics. In the case of tubular goods, however, the marking of the front fold disturbs, as it is caused by the material compression in this area during padding and the fleet wedge that forms between the padding rollers.
  • the invention is therefore based on the object of designing a method according to the preamble of claim 1 such that permanent bug marking is reliably avoided even in the case of materials which are difficult to treat and a formulation which is not optimally set.
  • a device according to the invention for dyeing tubular goods with reactive dyes is the subject of claim 7.
  • Appropriate embodiments of the invention are contained in the subclaims.
  • the tubular fabric is squeezed again after the bow marking has been laid, but before it remains cold.
  • the device for dyeing tubular fabric 1 with reactive dyes shown in FIG. 1 contains a first padding stage 2, which essentially consists of a chassis 3 containing the dye solution and a padder nip roller pair 4.
  • the tubular fabric 1 impregnated with dye solution in the first padding stage 2 then reaches a spreader 5 and a device 6, which is only indicated schematically, in which the plane in which the tubular fabric 1 is kept wide is rotated by approximately 90 °.
  • the bow marking formed in the first padding stage 2 on the two edges of the tubular fabric 1 held wide reaches the central region of the tubular fabric 1 now held wide in another plane (perpendicular to the plane of the drawing in FIG. 1).
  • the tubular fabric 1 passes over deflection rollers 7, 8 to a second padding stage 9, which contains a chassis 10 and a padder nip roller pair 11.
  • a second padding stage 9 which contains a chassis 10 and a padder nip roller pair 11.
  • an alkali solution is applied to the tubular fabric 1.
  • the tubular fabric 1 then arrives at a dwell zone 14 via a deflecting roller 12 and a table device 13 (of course, the tubular fabric 1 can also remain in the form of a wrap instead of in the tabular state). It is advisable to stay at room temperature (so-called cold stay).
  • the bow marker is then moved through the device 6 by at least 10 °, preferably by approximately 90 °.
  • This second padding stage 9 has a small chassis 10; instead can. you also work in the gusset in the second foulard stage 9.
  • the visible middle bend caused by the dye becomes the first Squeeze (in the pair of squeeze rollers 4) equalized.
  • the new middle bend created by the alkali block is not visible since the alkali is applied in excess and also diffuses very quickly.
  • a liquid application between 10 and 70% (based on the weight of the dry tubular fabric) is expediently carried out.
  • the tubular material is kept wide by being inflated with air. Squeeze rollers 4 squeeze to 100% moisture content (based on the dry goods).
  • an additional load of 20% is applied to the tubular goods in the form of an alkali solution, which contains 8 g / 1 20% sodium hydroxide solution, possibly with a little table salt.
  • the tubular goods are deposited or rolled up with a total fleet content of 120%. After a usual dwell time and after washing out, a completely bug-free coloring is obtained.
  • FIGS. 2 and 3 A second exemplary embodiment of a device for carrying out the method according to the invention is illustrated in FIGS. 2 and 3.
  • This device contains a padding stage 15 with a chassis 16 and a padder nip roller pair 17 and is used for the joint application of a dye solution and an alkali solution to the tubular fabric 1.
  • the tubular fabric held wide by a spreader 5 After passing through the padding stage 15, the tubular fabric held wide by a spreader 5 reaches a device 6 through which the plane in which tubular fabric 1 is kept wide is rotated, for example by 90 °, so that the bow marking formed in the padding stage 15 is displaced , ie for example, is placed in the middle of the wide tubular goods.
  • the tubular fabric 1 then passes through a pair of squeeze rollers 18, the crowned by two Squeeze rollers is formed (compare the - in Fig. 3 somewhat exaggerated with regard to crowning - representation).
  • the tubular goods are then fed to a dwell zone 14.
  • both dye and alkali are thus padded together in the padding stage 15 in the customary manner, a bow marking being formed.
  • the crimped pair of squeeze rollers 18 is then squeezed so that the bow marking is pressed. Due to the spherical design of the pair of squeeze rollers 18, the squeeze pressure acts only in the central region (i.e. where the bow marking is located) and then gradually decreases to the outside, so that there is no need to fear the formation of a second bow marking.
  • the pinch pressure exerted by the pair of squeeze rollers 18 in the region of the bow marking is expediently lower than the squeeze pressure exerted in the padding stage 15. It has a maximum value at which just no fleet is squeezed out of the tubular goods.
  • the roller diameter can be in the middle, for example, be about 1 cm larger than the outside. In this way, small and large hose diameters can be used in the same way.
  • Squeeze rollers 17 squeeze to a liquid content of 85%.
  • the plane in which the tubular goods are kept wide is rotated by 90 ° for laying the bow marking.
  • the middle bow is then leveled without a new bow marking being created.
  • the goods are then put down and stay until the dye is fixed. The result is a completely level coloring without any bow marking.
