Definitions

  • the present invention relates to a continuous process for dyeing textile webs, the web being impregnated with an aqueous liquor which contains dissolved and / or dispersed dyestuffs, at a temperature between 20 and 95 ° C., and the dyestuffs are removed in a steam / Air mixture fixed, characterized in that the impregnated web is not dried before the dye fixation, the drying temperature of the steam / air mixture is kept between 110 and 140 ° C, the steam content of the steam / air mixture so it is dimensioned that the wet temperature of the wet web is between 50 and 95 ° C and the fixing time is at least 20 seconds.
  • Block drying and block heat setting processes are known, which are carried out in most cases on the pre-dried textile material. If damp textile goods are used for the dye fixation program, they are dried when entering the heat treatment field. As a variant of the dry fixing method, the drying speed has also been influenced by regulating the steam content in the drying medium (DE-A-25 52 562). A lot of energy is used both for drying and for heat setting. Another disadvantage here is the migration that takes place during the drying process, which can lead to uneven dyeings.
  • Block-steaming processes are also known, which, regardless of whether they are used as one- or two-bath processes, are very energy-intensive.
  • the dye is first impregnated; the fixing chemicals are then applied in a second padding process, which is why these processes are also known as chemical pad-steam processes.
  • These processes are even more energy-intensive because the textile material is both dried and steamed. This takes place at 103-105 ° C. Intermediate drying also takes place in the one-bath block-steaming process, which is why the same disadvantages of high energy consumption apply here.
  • the task set was thus to avoid the disadvantages mentioned above, to enable good dye fixation with good colouration and to be able to work at a high production speed using a method which nevertheless saves energy.
  • This object is achieved by the method according to the invention, as described at the outset.
  • the dyes are fixed at a temperature of 50-95 ° C. of the moist tissue (so-called "wet temperature”) over a period of at least 20 seconds and generally not more than 200 seconds. However, in individual cases, depending on the dye used or the textile material to be dyed, the required fixing time can also be more than 200 seconds.
  • the specified temperature range of 50-95 ° C of the damp tissue is determined by the ratio of water vapor and air in the steam / air mixture.
  • the temperature of the moist fabric web corresponds to the temperature of a thermometer kept moist in the existing steam / air mixture.
  • Psychrometers work according to the same principle to determine the air content in a vapor / air mixture.
  • the temperature of the steam / air mixture of 110-140 ° C is measured with a dry thermometer.
  • a hot flue equipped with additional infrared emitters is expediently used for the dyeing process according to the invention, which also offers the possibility of steam injection. Because the infrared emitters are located inside the fixing chamber, the energy supplied by these emitters is not lost. The steam is advantageously supplied on the intake side of the air.
  • the steam consumption in the process according to the invention is significantly lower.
  • no excess pressure is required.
  • the advantage of heating up the equipment used, for example a hot flue, is that the metal parts of the equipment are preheated with hot air before steam injection begins. This prevents condensation of the steam on the cold metal parts, which not least also significantly reduces the risk of water dripping. Since the dye fixation works at a wet temperature of 95 ° C or below, there is a vapor / air mixture. At a wet temperature of approximately 80 ° C., the steam content in the fixing chamber is below 30% by volume. This makes it possible, for example, to dispense with the use of stainless steel, which is particularly cost-effective for the construction of fixing devices for the dyeing process according to the invention.
  • the steam injection to produce the desired steam / air ratio can be done in a known manner Can be controlled very precisely by a psychrometer, which means that little steam is used. Because the goods are practically unable to dry, there is no dye migration and the result is optimal dyeing.
  • the advantages of the new process are mainly due to the possibility of saving energy, since you work with a lower proportion of steam compared to working in a steamer at 100-105 ° C.
  • a steamer at 100-105 ° C.
  • an air freedom of about 95 vol .-% is achieved, which is even for many dyes that are fixed in the presence of reducing agents, i.e. are sensitive to oxidation to atmospheric oxygen, is sufficient.
  • the following dyes can be used in the process according to the invention: reactive dyes, acid dyes, 1: 2 metal complex dyes, Leuco Küpenester dyes, dispersion dyes, cationic dyes and soluble sulfur dyes.
  • alkaline agents can be used for the reactive dyes on cellulose fibers.
  • fixation in the strongly acidic and weakly acidic range can also be considered in the neutral and weakly alkaline range.
  • the acid dyes and metal complex dyes are used for dyeing wool or polyamide fibers or mixtures of these fibers, the disperse dyes for dyeing polyamide fibers and modified polyester fibers.
  • Cationic dyes can be used for dyeing both acid-modified synthetic fibers and polyacrylonitrile fibers (e.g. in the gel state), if necessary in the presence of fixing accelerators).
  • Suitable modified polyester fibers are both the acid-modified polyester fibers and carrier-free dyeable fibers made from polyethylene terephthalate modified with hydroxycarboxylic acids or aliphatic dicarboxylic acids or from a polyethylene terephthalate modified with polyethylene oxide in the form of a block polymer.
  • the dye yield corresponds to that of a dyeing which was steamed in a 100% steam atmosphere for 30 seconds at 103 to 105 ° C. and then developed.
  • fixation for 2 minutes at a wet temperature of 60 ° C. and a dry temperature of 110 ° C. results in coloring with the same dye yield.
  • a dark brown coloration is obtained which, in terms of hue and dyeing yield, differs practically from a coloration which was fixed for 60 seconds at 103 ° C. in a 100% steam atmosphere.
  • the fixing process is carried out at 103 ° C. for 60 seconds in a 100% steam atmosphere, a significantly lighter color is obtained.
  • a luminous Schlarach coloration with good fastness properties is obtained without a gray haze.
