Definitions

  • alkaline peroxide bleaching baths such as those used for bleaching cellulose
  • the bleaching liquors also contain wetting agents of an anionic or nonionic type, such as, for. B. alkanesulfonates or alkylbenzenesulfonates or adducts of ethylene or propylene oxide with compounds with active hydrogen, such as. B. alcohols or phenols.
  • wetting agents are intended to ensure uniform and quick wetting of the goods.
  • foam formation can be expected when using anionic and nonionic wetting agents, which can lead to considerable practical difficulties.
  • bleaching liquors which of course have to be alkali-stable, temperature-stable and peroxide-stable.
  • Bleaching formulations always contain an abundance of individual components and the task is to find substances that meet all of the above requirements at the same time.
  • alkyl polyglycol tert-butyl ethers are suitable as stabilizers in alkaline peroxide bleach baths and that these compounds act simultaneously as a low-foam to foam-free wetting agent.
  • the invention therefore relates to the use of compounds of the general formula wherein RC 6 -C 22 alkyl, C 6 -C 22 alkenyl or C 6 - C 2 2 -arylaryl, n is a number from 5 to 50 and X is ethylene or propylene, the ether chain (X - O) n being complete consists of ethoxide units or has at most n / 5 isopropoxy units, as an aid in alkaline peroxide bleaching baths.
  • the compounds of the above formula are known from DE-A-2 556499.
  • Preferred compounds are those in which RC 8 -C 18 alkyl, C 8 -C 18 alkenyl and Cs - Cw alkylaryl.
  • the alkyl or alkenyl groups can be straight-chain or branched.
  • the phenyl group is preferred as the aryl.
  • the bleaching bath has the usual composition and contains hydrogen peroxide or compounds which form hydrogen peroxide in aqueous solution as the bleaching agent.
  • the pH of the bleaching containers is adjusted to 9 to 14, preferably 11 to 13, with alkali such as sodium hydroxide or sodium carbonate.
  • alkali such as sodium hydroxide or sodium carbonate.
  • 0.5 to 5, preferably 0.5 to 3 g / l of the auxiliary of the above formula are added to this bleaching bath.
  • higher amounts of the auxiliary are used up to about 20 g / l.
  • the compounds of the above formula can be used individually or as a mixture with one another, anhydrous or in the form of aqueous preparations. Of course, it is also possible to use conventional stabilizing, wetting and anti-foaming agents.
  • the freedom from foam of the alkyl polyglycol tert-butyl ether is particularly given when the temperature of the bleaching bath is above the cloud point of these auxiliaries, so that this auxiliary is wholly or partially clouded. If the compounds of the above formula are used below their cloud point, a certain amount of foam is achieved, but not completely free of foam. Accordingly, the preferred temperature for bleaching is about 60 to 100 ° C.
  • the cloud point of the auxiliaries described above can be varied by adding oxyethylated alkylphenols, e.g. B. be increased.
  • the proportion of these ethoxylated alkylphenols, with nonylphenol having 5 to 50 ethylene oxide units being preferred, can be up to about 95% by weight, based on the sum of alkylpolyglycol tert-butyl ether and alkylphenol oxalkylate.
  • the peroxide degradation is followed up to a duration of 2 hours. Bleaching times between 10 and 30 minutes are of practical importance.
  • the cellulose material to be bleached can consist of cotton, linen, nettle, jute, regenerated cellulose and mixtures of cellulose with synthetic fibers. After the bleaching process, the bleach is washed and dried. The degree of whiteness, absorbency and degree of polymerization are then determined as effectiveness criteria.
  • the stabilizing effect of the alkylpolyglycol tert-butyl ether is ti t rimetwitz determination of the peroxide during the bleaching operation detected.
  • the foaming behavior of the bleaching liquors is determined at 80 ° C.
  • the bleaching liquor is circulated through a vertical pipe in laboratory tests. After exiting the tube, the liquor jet falls 30 cm onto the liquor located in a calibrated, heatable vessel, the height of the amount of foam formed after one minute being measured and the time degradation of the foam being monitored.
  • Raw cotton jersey was bleached on a reel runner in a 1:20 liquor ratio with a bleaching liquor I of the following composition:
  • the bleaching liquor was heated to 90 ° C. in 30 minutes and kept at this temperature for 120 minutes.
  • the water in the bleaching liquor was a mixture of tap water and electric water in a ratio of 1: 1 with a German hardness of approx. 10 °.
  • the consumption of peroxide was determined titrimetrically with potassium permanganate every 15 minutes. After the bleaching process was completed, the goods were rinsed at 70 ° C., the goods were spun off and dried.
  • bleaching was carried out under the same conditions with a previously usual bleaching liquor II of the following composition:
  • Desized cotton fabric was padded with a bleaching liquor I or II of the composition given below and heated to 90 ° C. with direct steam for 30 minutes. It was then rinsed cold twice at 60 and twice.
  • the fleet 1 is foam-free, while the fleet 2 foams very strongly.
  • the following results were obtained with both bleaching liquors:
  • the bleaching liquor I has the advantage that it does not foam.
  • a bleaching liquor containing 50 ml / l of hydrogen peroxide, 18.75 g / l of caustic soda and 6 g / l of a mixture of 84% of the alkyl polyglycol tert-butyl ether used in Example 1 and 16% of an oxyethylated nonylphenol with 23 units of ethylene oxide was passed through a Time of 72 hours examined for the content of peroxide.
  • the water in this bleaching liquor consisted of a mixture of deionized water and tap water in a 1: 1 ratio. A 10% reduction in the peroxide content was observed.
