Definitions

  • the invention relates to a stable brightener dispersion and its production and its use for the optical brightening of textile fiber materials, in particular polyester materials.
  • Aqueous dispersions of water-insoluble or poorly soluble optical brighteners are known (DE-AS-2745872, DE-OS-2816746). Disadvantages of these brightener dispersions include their low storage stability and their low lightening effect at temperatures of 160-190 ° C in the block thermosol process. It has now been found that the addition of specific synthetic copolymers surprisingly eliminates these disadvantages.
  • the new brightener dispersions are stable for several months at temperatures up to 40 ° C and, after application by means of a block thermosol process, show a higher degree of whiteness on polyester fiber material than known brightener dispersions, despite the use of the same brighteners with the same active ingredient concentrations.
  • the invention thus relates to new stable, aqueous brightener dispersions comprising at least one water-insoluble or poorly soluble optical brightener, at least one anionic, cationic and / or nonionic dispersant and, if appropriate, other auxiliaries, characterized in that the dispersion additionally comprises a copolymer of 2-vinylpyrrolidone with 3- Contains vinyl propionic acid.
  • the dispersion according to the invention preferably contains 4-20% water-insoluble to sparingly water-soluble optical brighteners, 2-20% dispersants, 1-15% copolymer of 2-vinylpyrrolidone with 3-vinylpropionic acid and 0.1-25% other auxiliaries.
  • dispersions which contain 8-15% brightener, 2-10% dispersant, 2-10% copolymer of 2-vinylpyrrolidone with 3-vinylpropionic acid and 0.1-20% other auxiliaries.
  • the percentages here and below relate to percentages by weight.
  • the water-insoluble or poorly soluble optical brighteners are compounds or mixtures of compounds e.g. from the class of the stilbenes, distyryl-benzenes, diphenyl-distyryl, triazinyls, benzoxazoles, bis-benzoxazoles, bis-benzoxazolylthiophenes, bis-benzoxazolylnaphthalenes, pyrenes, coumarins and naphthalene-peri-dicarboximides.
  • Preferred compounds correspond to the formula:
  • M Li, Na, K, ammonium or C 1 -C 4 alkylammonium and the mixtures I to VI of compounds of the formulas:
  • the cationic, anionic and / or nonionic dispersants are the usual dispersants for water-insoluble or poorly soluble brighteners.
  • Anionic dispersants include, for example, condensation products of aromatic sulfonic acids with formaldehyde and lignin sulfonates.
  • Formaldehyde condensation products with naphthalene sulfonic acid and dihexyl sulfosuccinates are particularly suitable.
  • Quaternary fatty amine polyglycol ethers are suitable as cationic dispersants.
  • nonionic dispersants are preferably used.
  • Ethylene oxide adducts from the class of addition products of ethylene oxide with higher fatty acids, saturated or unsaturated fatty alcohols, mercaptans, fatty acid amides, fatty acid alkylolamides or fatty amines or with alkylphenols or alkylthiophenols with at least 7 carbon atoms in the alkyl radical, with 1 mol of the above mentioned Compounds preferably 5 to 100 moles of ethylene oxide come, as well as ethylene oxide-propylene oxide block polymers and ethylene diamine-ethylene oxide-propylene oxide adducts.
  • Some of the ethylene oxide units can be replaced by other epoxides, e.g. Styrene oxide or in particular propylene oxide can be replaced.
  • the dispersion according to the invention can contain other auxiliaries, for example textile auxiliaries, shading dyes, foam-suppressing agents, in particular antifreeze agents such as e.g. Polyols, in particular di- or polyalcohols such as ethylene glycol, propylene glycol, diethylene glycol, glycerin and / or sorbitol, humectants, surfactants such as e.g. Polyethylene glycols with molecular weights between 200 and 6000 and / or antimicrobials such as Contain chloroacetamide or aqueous formalin solutions as well as fungicides.
  • auxiliaries for example textile auxiliaries, shading dyes, foam-suppressing agents, in particular antifreeze agents such as e.g. Polyols, in particular di- or polyalcohols such as ethylene glycol, propylene glycol, diethylene glycol, glycerin and / or sorbitol, humectants,
  • the brightener dispersion contains a copolymer of 2-vinylpyrrolidone with 3-vinylpropionic acid. These copolymers are known and can be prepared by known methods.
  • the brightener dispersion according to the invention is produced, for example, a) by mixing the separately manufactured and formed individual components or b) by jointly forming the individual components e.g. by grinding in a microsol, pearl, sand or dyno mill to a particle size of less than 5 microns.
  • the brightener dispersions according to the invention are used for the optical brightening of textile fiber materials, preferably polyester fiber material.
  • the application takes place according to known application methods, preferably according to a block thermosol method. It is also possible to lighten polyester / cellulose blended fabrics.
  • the application is then carried out either by a one-step process with the addition of a cellulose brightener, in which case the polyester and cellulose components are lightened simultaneously, or by a two-step process, in the first step the polyester component using the brightener dispersion according to the invention and in the second step with the addition of a cellulose brightener Cellulose content can be lightened.
  • Example 1 40 parts of the brightener mixture I
  • Example 1 40 parts of the brightener mixture I or II according to Example 1 or 2, 20 parts of a nonionic dispersant as in Example 1 and 140 parts of water are ground in a microsol mill as in Example 1. After the glass beads have been separated off, a homogeneous, easily pourable and pumpable liquid form with a brightener content of 20% is obtained. 100 parts of this liquid form are mixed with 10 parts of 1,2-propylene glycol, 16 parts of 30% aqueous 2-vinylpyrrolidone / 3-vinylpropionic acid copolymer, 1 part of 37% formaldehyde and 73 parts of water in a beaker while stirring. A low-viscosity dispersion with a brightener content of 10% is obtained, which remains stable in storage at room temperature and 40 ° C. for a long time and has no sedimentation.
  • the dispersions are no longer stable in storage; they sediment after a short time.
  • a polyester fabric (Terylene type 540) is treated at 40 ° C. on a dyeing machine at a liquor ratio of 1:20 with an aqueous bath containing 1 g of brightener preparation according to Example 1, 2 or 3 and 1 g / l of a fatty alcohol polyglycol ether. The temperature is raised to 130 ° C. within 30 minutes and left at this level for a further 30 minutes. Then you cool down to 40 ° C within 15 minutes. For the after-treatment, the textile is rinsed in flowing deionized water for 30 seconds and dried at 180 ° C. The polyester fabric treated in this way has a high lightening effect.
  • a polyester fabric (Terylene type 540) is padded at room temperature with an aqueous liquor containing 1 g of brightener preparation according to Example 1, or 3 and 1 ml / l of alkylphenol polyphenol ether. The squeezing effect is 65%. It is then dried for 30 minutes at a temperature of 80 ° C and then heat set at 200 ° C.
  • the polyester fabric treated in this way has a higher lightening effect than if the same preparation is used, but which instead of 2-vinylpyrrolidone / 3-vinylpropionic acid copolymer contains a polyvinyl alcohol which is preferably used in practice.
