  • US-A-3 621 081 discloses the oligomeric phosphonic acid esters used according to the invention. According to US Pat. No. 3,621,081, these oligomeric phosphonic acid esters are used thanks to their sequestering properties, above all for calcium ions, as softening agents in water treatment and as builders in detergents.
  • the present invention thus relates to a process for bleaching cellulose-containing fiber materials with aqueous, peroxide-containing, alkaline liquors, characterized in that liquors are applied to the fiber materials by adding water-soluble oligomers of the formula or their alkali metal salts are stabilized, in which Y is hydrogen or -CO-T1, R 1 , Q, and T, are each alkyl having 1 to 4 carbon atoms, and n 1 is 1 to 16, and then the fiber materials are stored in a moist state .
  • oligomers according to formula (1) as stabilizers in aqueous, peroxide-containing, alkaline liquors for bleaching cellulose-containing fiber materials and the bleaching liquor for carrying out the bleaching process, which contains oligomers according to formula (1) as stabilizers, are further objects of the present invention Invention.

  • Suitable alkyl radicals for R 1 , Q 1 and T are isobutyl, preferably isopropyl, especially n-butyl and n-propyl and in particular ethyl and methyl, methyl being particularly preferred.
  • Y 1 is -CO-T 1
  • T and R preferably have the same meanings. Hydrogen as the meaning of Y, however, is of primary interest.
  • the limit values for n are 1 and 16. Preferred values are 1 to 12, the main constituent of the mixture being oligomers with average values for n of about 5 to 9, preferably about 5 or 6. Oligomers with n - 1 and oligomers with n - 12 to 16, especially 12, are always present in smaller amounts in the mixture.
  • Oligomers of the formula are preferred or their sodium or potassium salts, in which Y 2 is hydrogen or -CO-R 1 , n 2 1 to 14 and R 1 has the meaning given, and in particular the formula or their potassium salts, wherein R 2 is methyl or ethyl and n 3 is 1 to 12.

  • the potassium salts of the oligomers are preferred over the sodium salts because of their higher solubility.
  • the oligomers according to formula (1) can also be used in combination with other stabilizers such as e.g. Aminoalkanediphosphonic acids according to DE-A-2 625 767 or DE-A-2 115 737 are used in the bleaching liquors according to the invention.
  • other stabilizers such as e.g. Aminoalkanediphosphonic acids according to DE-A-2 625 767 or DE-A-2 115 737 are used in the bleaching liquors according to the invention.
  • the process according to the invention for bleaching cellulose-containing fiber materials using the oligomers of the formula (1) for stabilizing the aqueous, peroxide-containing alkaline liquors is carried out in such a way that the bleaching liquors are first applied to the fiber material, as a rule, e.g. by immersion and preferably by padding in e.g. 10 to 60 ° C, but preferably at room temperature (15 to 25 ° C), the liquor absorption after squeezing is about 50 to 120, preferably 90 to 110 percent by weight.
  • the fiber material After impregnation, the fiber material is usually subjected to a so-called wet storage or wet storage process without drying in the wet state or after squeezing in the padding process while still wet, in which the material is rolled up in an airtight manner, if necessary in a plastic film and optionally under pressure at a maximum of 150 ° C for about 10 minutes, but preferably under normal pressure at 80 to 98 ° C for about 1 to 5 hours or in particular at room temperature (15 to 25 ° C) for about 10 to 30 hours .
  • the treatment of the fiber materials can also be carried out in so-called long liquors (exhaust processes) with a liquor ratio of e.g. 1: 3 to 1: 100, preferably 1: 8 to 1:25 at 20 to 100, preferably 80 to 98 ° C.
  • the pull-out can also be carried out up to 150 ° C under pressure in so-called high-temperature equipment (HT equipment). If the bleaching takes place in the exhaust process, the fiber material is at the specified temperatures and during the specified times in the apparatus used for the extraction, e.g. in a reel skid.
  • Continuous processes are particularly important in industrial operation, in which similar residence times for the fiber material in the bleaching liquor are required at the temperatures indicated. Treatment temperatures of 98 ° C are advantageously not exceeded in order to prevent any fiber damage. With special HT equipment, however, the fiber materials can also be used in industrial continuous processes under pressure up to e.g. 2.5 bar at higher temperatures, e.g. up to 150 ° C, if the treatment time is kept so short that fiber damage is excluded.
  • the fiber materials are then generally rinsed thoroughly with hot water at around 90 to 98 ° C and then with cold water, if necessary with e.g. Neutralized acetic acid and then dried preferably at elevated temperatures (e.g. up to 150 ° C).

  • Preferred anionic surfactants are e.g. Alkylarylsulfonates, fatty acid condensation products, protein cleavage products or their salts and especially alkylsulfate salts and alkylbenzenesulfonic acids with 12 to 22 carbon atoms in the alkyl radical.
  • Preferred nonionic surfactants are e.g. Adducts of alkylene oxides, especially propylene and especially ethylene oxide and alkylphenols with e.g.
  • the preferred optional component (f) are higher alcohols, e.g. Isooctyl alcohol, but especially silicone-based defoaming and / or deaerating agents, in particular silicone oil emulsions.
  • Components (e) and (f) are preferably combined with commercially available aqueous, about 10 to 60, preferably 30 to 40 percent by weight formulations of non-foaming surfactant mixtures.
  • the preferred optional component (g) is e.g. water-soluble alkali metal silicates, in particular soda-water glass with a content of 24 to 28% SiO, especially as aqueous, about 30 to 40 weight percent solutions.
  • optical brighteners used as optional component (h) generally belong to the styryl and stilbene series, e.g. Distyrylarylenes, diaminostilbenes, ditriazolylstilbenes, phenylbenzoxazolylstilbenes, stilbene naphthotriazoles and dibenzoxazolylstilbenes.
  • Optical brighteners of the distyrylbiphenyl or bistriazinylaminostilbene type which contain sulfonic acid groups, e.g.

These are preferably used as commercially available aqueous, about 20 to 30 percent by weight liquid formulations.
  • bleaching liquors are used in the continuous process, it may be necessary to have reinforced, approximately 3 to 5 times stronger bleaching liquors (bleaching liquors with 3 to 5 times the concentration) as so-called make-up or storage baths in order to reduce the concentration of the bleaching bath after bleaching a certain amount of material.
