Definitions

  • the present invention relates to an apparatus and a method for Finishing, especially dyeing, of textile goods using the exhaust process a short fleet ratio in a very short time.
  • An isothermal treatment method is known from EP-A 0 014 919, in the case of the hot preheated material to be treated with a hot treatment liquor a conventional jet system is brought into contact, part of the Treatment fleet the goods storage space, the other part of the jet nozzle is supplied and the goods drive either by a gas or by a liquid (i.e. the liquor) or by both together.
  • the dyeing liquor is applied to the material in such a way that it is in atomized form is injected into the circulated gas stream, the Textile goods and the treatment fleet not absorbed by the material always circulated again.
  • the order for the entire fleet is made via distributed several circulation of goods, and through the ongoing recirculation of the Excess fleet will spread evenly across both the fleet and reached as well in the strand.
  • After completing the dyeing operation it will material dyed in one piece removed from the jet. This procedure is described in a conventional jet system with an additional device for atomizing or dusting the treatment agent into the driving gas stream is executed.
  • a disadvantage of the above-mentioned processes is, for example, that pure cellulosic articles still with a relatively long fleet of 1: 6 to 1: 8 must be worked and therefore large amounts of thermal energy are necessary to to heat these liquor quantities to the required temperatures. Moreover with these processes the jet system inevitably contains large quantities excess, freely circulating fleet, so that the goods in the whole System, even in the store, is in contact with the fleet. The consequence of which is a relatively long drawing process of the dye and a even longer dosing and fixing process.
  • the object of the present invention was therefore to provide a device or a Find method that does not have the disadvantages mentioned and with fleet ratios as short as possible and dyeings higher in the shortest possible time Quality delivers.
  • the present invention thus relates to a device for refining Textile, essentially comprising a container (1) with goods inlet (2), at least one nozzle (3) for applying a treatment liquor, the Nozzle can be goods inlet, intensive section (4) and goods outlet at the same time (5), characterized in that the container has no goods store and a precise fit of the nozzle (3) and intensive care section (4) into the container (1) minimized dead volume.
  • the present invention further relates to a method for refining Textile material, which is characterized in that it is in an inventive Device is running.
  • the device according to the invention enables the finishing of textile goods strands essentially only by one consequent separation of fleet and goods flow after each passage of the device according to the invention.
  • Fiber materials containing hydroxyl groups are, for example, cellulosic Fiber materials such as natural fiber materials such as cotton, jute and linen, and those made from cellulosic natural materials modified fiber materials, such as from regenerated cellulose, such as Viscose silk, and modified with compounds containing amino groups Cellulose fibers, such as those from the U.S. patents
  • Fiber materials containing carbonamide groups are natural fiber materials, such as wool and other animal hair and silk, and also synthetic polyamide fiber materials, such as fiber materials made of polyamide-6, polyamide-11 and polyamide-6, 6.
  • Water-soluble dyes are in particular those of an anionic nature, for example the so-called acid and direct dyes, but especially fiber-reactive dyes (reactive dyes).
  • fiber reactive dyes in particular to emphasize those that form a residue of the Have vinyl sulfone series, such as the vinyl sulfonyl group or one Ethylsulfonyl group, which is in the ⁇ -position by an in alkaline medium eliminable substituents is substituted, such as the ⁇ -sulfatoethylsulfonyl, ⁇ -acetoxyethylsulfonyl, ⁇ -chloroethylsulfonyl or ⁇ -thiosulfatoethylsulfonyl group, furthermore fiber-reactive residues from chlorotriazinyl, fluorotriazinyl, Fluoropyrimidinyl, chlorofluoropyrimidinyl and dichloroquinoxazinyl series as well Dyes
  • Dyeing processes can do all common circular and knitted articles, such as single Jersey, plush handles, interlock, fine rib, piquet and lining materials advantageous be treated.
  • finishing of woven goods is among the conditions according to the invention possible without problems.
  • the pre-treatment and post-treatment of the actual dyeing Textile goods which are also carried out with the aid of the device according to the invention, are in particular treatments for applying equipment, but primarily bleaching and washing processes.
  • the container (1) of the device according to the invention can in principle be any have any geometric shape, but is preferably cylindrical or cuboid. Due to the lack of a store and the exact Fitting the nozzle (3) and intensive care unit (4), the container (1) is compared with conventional jet dyeing systems very small and has one Volume of advantageously less than 150 liters. Particularly preferred it has a volume of 60 to 120 liters.
  • the inlet and outlet elements (2) and outlet (5) normally used for jet dyeing systems are usually the insertion and exit elements which, in the case of HT processes, also serve to seal the pressure. Such elements are known per se to the person skilled in the art and are described, for example, in DE-A 2537665 and DE-A 2325604.
  • the goods outlet (5) is preferably connected to a stripping device, for example a rubber lip, a metal ring or a conical cylinder piece, or is already designed as such.
  • the nozzle (3) is also usually a component which is customary in jet dyeing and is designed such that it is operated hydraulically with a flowing liquor by means of a pump (6) and the propulsion takes place while the textile material is impregnated at the same time. Propulsion can be additionally supported by other means known to those skilled in the art, such as, for example, reels or air nozzles.
  • the intensive section (4) usually consists of a cylindrical metal tube in which the goods to be treated are still in intensive contact with the treatment liquor for a short time.
  • the container (1) preferably has one or more openings (7) at the deepest point of its underside, through which excess liquor can drain and is preferably returned to the nozzle (3) in a circuit.
  • the container (1) is particularly preferably perforated on its underside for this purpose.
  • the device according to the invention can optionally have further components, such as a lint filter. If polyester is to be colored with disperse dyes, it must be equipped, for example, with appropriate heating devices in order to achieve the temperatures required for this.
  • preparation vessels for the liquor or other treatment liquids are also required. It is also advisable to store the part of the line of goods that is not currently passing through the device according to the invention in a clipboard or in a goods store, which is provided in a suitable manner with the device according to the invention. It is possible to construct the device according to the invention in such a way that the jet nozzle (3) also functions as goods inlet (2).
  • FIG. 1 shows an embodiment of the device according to the invention, but without restricting it to this form.
  • the container (1) is provided with a goods inlet (2) into which the textile material to be finished enters. It leaves the container (1) via the goods outlet (5) provided with a stripping device.
  • the jet nozzle (3) which, by means of a pump (6), presses the liquor first through the heat exchanger (9) and then into the nozzle (3).
  • the textile fabric strand which is moved forward by flowing liquor or alternatively also via reels (10), passes directly through the intensive route (4) after the nozzle passage and is brought to a defined moisture application in the goods outlet (5).
  • the medium required for the impregnation is ideally fed to the pump (6) via a feed vessel (not shown) directly via the feed line (11).
  • Excess liquor wiped off after passing through the intensive section (4) runs back into the container (1) and quickly reaches the suction side of the pump (6), for example via perforated sheets (7).
  • the liquor Via the outlet (8), the liquor can be removed directly into the batch vessel, for example in order to dissolve further chemicals with the liquor in circulation and then feed it back into the working medium.
  • the dead volume of the container (1) is minimized by precisely fitting the nozzle (3) and the intensive section (4), ie just as much free liquor is available for the pump (6) through the inlet via (11) and wiping off at (5) , as is necessary for the correct operation of the pump (6).
  • the device according to the invention thus differs from the usual pull-out dyeing in the jet in that the one to be treated Line of goods only in the small-sized container (1) with the treatment / transport fleet comes into contact, only circulate the fleet in this container can and therefore in the dyeing process the extremely short Fleet relationships can be realized.
