Definitions

  • the invention relates to a process for pretreatment, namely desizing and decoction, and optionally bleaching, of cellulose goods in which a Treatment liquor containing a per-compounds, such as hydrogen peroxide Pretreatment agent applied to the cellulose product and in the goods in the Pretreatment effect is brought to effect. It also relates to a method for applying the treating agents in reactive dyeing and dye fixing Cellulose product in which the product pretreated before dye fixing, namely desized, boiled and / or bleached.
  • cellulose product Under a web-shaped "cellulose product" are textile fabrics made of cellulose - Including cotton, viscose, regenerated cellulose and mixtures thereof with each other and / or with synthetic fibers - understood. The procedure is primarily to find application in textile fabrics, such as web or Knitted fabric, in principle, but also comes with the use of threads or sherds in question.
  • suitable per-compounds - short "Per" - which split off oxygen in solution, preferably by decomposition of hydrogen peroxide, are e.g. Perborates or percarbonates.
  • the respective treatment agent is preferably applied by dipping in a treatment vehicle fleet.
  • Desizing and decoction and optionally bleaching are among the preparatory operations, the so-called "pre-treatment", in textile finishing.
  • the purpose of desizing is to strip off all sizing the fiber of applied substances.
  • Starch-containing sizing agents can be desized with the help of enzymes.
  • an oxidative Desirability required.
  • a combined desizing, washing and bleaching process for raw textiles Cotton which is to be carried out continuously, is described in CH 560 789.
  • the cellulose product is moistened with an aqueous solution which is essential Ingredients an alkali metal hydroxide and per-compounds, such as hydrogen peroxide and peroxidiphosphate.
  • the goods are at a treatment temperature heated from about 80 to 135 ° C.
  • treatment temperatures of 100 ° C and atmospheric pressure contains the treatment room 100 vol.% Steam.
  • the im Known provided lower temperature limit of 80 ° C and atmospheric pressure Almost 100% by volume steam is also reached in the treatment room.
  • the goods are washed. Short treatment times of down to 1 minute are only at 135 ° C and 100 vol.% steam in the pressure vessel and accordingly discontinuous possible.
  • DE 31 24 961 A1 discloses a batch process for simultaneous dyeing and desizing. It is a cold dwell process, in the case of the paint and desizing agent (amylase) and soda, the treatment bath be added. After diving and squeezing and a liquor pick-up of about 70%, the textile is rolled up and - with a plastic wrap wrapped - stored for 24 hours at about 20 ° C and slow rotation. Subsequently Among other things, the goods are passed through a boiling soap bath. If If the product is to be bleached, the soap bath can be the bleaching hydrogen peroxide contain. The simultaneous dyeing and desizing process can namely with bleaching is not combined because the bleach would damage the paint.
  • the invention has for its object to provide a pretreatment process, which allows a continuous continuous driving, the pretreatment summarized essentially in a treatment unit or aggregate type, particular neutralizing agents for eliminating any residues of per-compounds not needed and - without overpressure - compared to the state of Technique requires shorter processing times of the treated textile product.
  • Another The task is to reduce the consumption of pre-treatment and dye-fixing total amount of chemical aids required in reactive dyeing, in particular to alkali substances, without the pretreatment success or affect the color yield.
  • the solution according to the invention is used for the initially mentioned method for pretreatment, in which per-compounds are used, described in claim 1. It is crucial in particular that the per-compounds by continuous Dry with circulating air are expelled from the cellulose product.
  • One Process for reactive dyeing and dye fixing in cellulose goods is in the claim 6 indicated.
  • the invention can be achieved that the water content in the textile when drying in approximately the same extent so at about the same speed is reduced, such as the proportion of per-compounds, in particular hydrogen peroxide, - At the respective treatment temperature - decays or consumed becomes.
  • concentration of per-compounds in each of the product still existing fleet remain approximately constant according to the invention should.
  • the rate of disintegration of the per-compounds e.g. according to their respective task and / or treatment temperature, -
  • the rate of disintegration of the per-compounds e.g. according to their respective task and / or treatment temperature, -
  • stabilizers or destabilizers - so to control that the disintegration and drying rates close to the approximately complete decomposition or consumption of the per-compounds approximately the same run.
  • the relative effect of the per-compounds changes - because of their almost constant concentration on the product - during the virtually the entire pretreatment process.
  • the actual pretreatment process, followed by a further drying of the goods can be considered completed when the per-connections have completed their task.
  • the amount of per-compounds used can be sized that the latter - at (initially) approximately constant concentration on the goods - consumed at the end of the pretreatment process to an absolutely imperceptible level are. Because of any remains of the per-compound is therefore a washing, e.g. before dyeing, not required. The acquaintance had to wash it or neutralized because of the concentration of per compounds in the treatment liquor within the goods constantly decreased and - when towards the end of Process should have any effect at all - the per-connections (initially) were to be supplied in excess.
  • the method according to the invention can be carried out when hot and humid - not wet-hot - drying air is used.
  • the invention used Drying air should contain only so much moisture that an approximate Synchronization of drying speed of the product and decay rate the Per connection used is achieved. A drying air that meets these conditions is met, is referred to in the invention as "wet-hot”.
  • the pretreatment according to the invention should preferably be in one with circulating air operated air dryer, whose "hot-humid" drying air a the Drying rate per se elongating steam content, in particular of the order of magnitude about 30% by volume of steam.
  • This measure can be significant, e.g. vary by ⁇ 10% by volume. So it becomes an atypical operated air dryer provided that not - as usual - with the lowest possible water vapor content, but operated with relatively high water vapor content in the circulating air becomes.
  • the water vapor content should be so low that in any case a constant drying takes place during the treatment process and a Residence time within the circulating air of 2 to 5 minutes suffices to dry, when the temperature of the circulating air in the order of 100 ° C and more lies.
  • the aforementioned lower limit of the duration of treatment about 2 minutes, becomes defined by the time in which the proportion of per-compounds, e.g. hydrogen peroxide, depending on the height of the treatment temperature to a no longer disturbing degree consumed or chemically disintegrated.
  • the upper limit of the treatment duration is determined by the quality, in particular the severity, of the treated product. For light goods, a total treatment time may be sufficient, which is about the same the consumption or disintegration time of the per-connections.
  • the actual pretreatment is completed after the aforementioned minimum time. So if another Drying of the goods is not required, this pre-treatment can be stopped.
  • a treatment liquor containing a pretreatment agent loaded cellulose product (generally after immersion in the pre-treatment bath) continuously passed through the moist-hot drying air and there by the effect of damp heat on the pretreatment - in spite of the Moist continuous drying of the goods - at the same time desized, boiled and optionally bleached.

Preferably, this is done by soaking or dipping in one or several with each subsequent squeeze continuously connected in series Foulards. Between every two foulards, e.g. for better wetting, a dwell, e.g. an aisle, especially with a few tens of seconds Dwell time, be turned on. The squeezing effect can be adjusted be that the goods get into the air dryer with the usual residual moisture levels.
