Definitions

  • the invention relates to mixtures containing a glycerol-C6 ⁇ 22 fatty acid ester hydrate with a water content between 5 and 30 wt .-% and a monoglyceride content, based on glycerol fatty acid ester, between 50 and 95 wt .-%, a stabilizer and a carbohydrate, and the use of such a mixture as a thickener in textile printing pastes.
  • Textile printing pastes contain thickening as an important component.
  • Thickenings are those parts of the printing paste which, mainly composed of thickening agents, give an aqueous, dye and chemical-containing liquor a printable, pasty consistency.
  • thickened portions are called stock thickenings (Ullmanns Encyklopadie der Technische Chemie, Volume 22, pages 583-587, Verlag Chemie Weinheim (1982)).
  • the Brookfield viscosity of a stock thickening at 20 ° C is typically between 35,000 and 50,000 mPas.
  • thickeners are powdery or granular substances or viscous concentrates with a pronounced swelling capacity in water. They form colloidal systems with water and can therefore increase the viscosity of dye and chemical solutions.
  • the thickeners must be compatible with the dyes and chemicals intended for printing pastes, must not react with them and should not be stained themselves, if possible, or only evenly. Only a few thickeners, such as alginates, satisfactorily meet these requirements. However, due to the limited and fluctuating availability of this polysaccharide, there is a need for an equivalent replacement that is always available in sufficient quantities.
  • glycerol soya oil fatty acid esters with a monoglyceride content of 34 and 40% by weight is known.
  • These glycerin fatty acid esters are used as water-containing, pasty pressure thickeners in reactive and dispersion printing and are characterized by good washability, good color depth and the absence of hardening after washing the textile material.
  • the print image obtained on the textile material with a paste containing glycerol soybean oil fatty acid ester has a poor contour level.
  • the production of a printing paste containing glycerol fatty acid esters requires temperatures between 60 and 90 ° C.
  • the use of mixtures of glycerol soya oil fatty acid esters with a monoglyceride content of up to 40% by weight and sodium alginate leads to a deterioration in the color depth.
  • the object underlying the invention was to develop thickenings for textile printing pastes, which are always available in sufficient quantities and with those in printing pastes containing dyes and auxiliaries are compatible and do not react with them, have a high storage stability at temperatures between 18 and 25 ° C and can be processed to thickened stocks at temperatures between 18 and 25 ° C. Furthermore, the textile materials which are treated with a printing paste which contains such a thickening and can be produced at temperatures between 18 and 25 ° C. should have an excellent printed image and a very good depth of color.
  • the high demands placed on the thickenings to be developed are met by mixtures containing a glycerol-C6 ⁇ 22 fatty acid ester hydrate with a water content of between 5 and 30% by weight and a monoglyceride content, based on glycerine fatty acid esters, of between 50 and 95% by weight. , a stabilizer and a carbohydrate in certain amounts.

  • a mixture containing 40-85 parts by weight of a glycerol-C Gly22 fatty acid ester hydrate is preferred. 5 - 30 parts by weight of a stabilizer and Contains 10 - 40 parts by weight of a carbohydrate.
  • Glycerol-C6 ⁇ 22-fatty acid ester hydrates with a water content between 5 and 30 wt .-% and a monoglyceride content, based on glycerol fatty acid esters, between 50 and 95 wt .-% are known compounds, for example according to EP-A-63 468 by mixing Glycerol fatty acid esters with a monoglyceride content between 50 and 95 wt .-% and water at temperatures between 20 ° C and the temperature of the melted glycerol ester are accessible.
  • Suitable monoglyceride-containing glycerol fatty acid esters have iodine numbers ⁇ 10, preferably ⁇ 5 and fatty acid residues with preferably 12-22 carbon atoms, particularly preferably 16-22 carbon atoms.
  • Glycerol fatty acid esters with a monoglyceride content between 50 and 95% by weight are produced by known methods by disproportional transesterification of fats and oils, for example beef tallow, hardened lard, hardened rapeseed oil, palm fat and / or coconut fat, with glycerin in the presence of a preferably alkaline catalyst at temperatures between 160 and 250 ° C or by reacting fatty acids, for example stearic and / or palmitic acid, with glycerol under acid catalysis (Ullmanns Encyklopadie der Technische Chemie, 4th edition, volume 22, pages 494-495, Verlag Chemie Weinheim 1982 ).
  • a mixture according to the invention is preferably prepared in such a way that a stabilizer during the preparation of the monoglyceride-containing glycerol C6 ⁇ 22 fatty acid ester hydrate or directly the glycerol C6 ⁇ 22 fatty acid ester hydrate with a water content of between 5 and 30% by weight and a monoglyceride content , based on glycerol fatty acid esters, between 50 and 95 wt .-% is added at temperatures between 18 and 25 ° C.
