Definitions

  • the invention relates to a method for removing stains from textiles or the like, in particular for removing ball or pens.
  • two basic substances can be used for removing stains from textiles or the like, namely the so-called wash-active substances which, in interaction with water, loosen the soiling from the fiber surface so that they are absorbed by the washing liquor.
  • So-called grease soiling is emulsified in the washing liquor and so-called pigment soiling is suspended in the washing liquor.
  • solvents are used instead of detergent-active substances, which may have to be matched to the chemical structure of the stain in question.
  • 1.1.1-trichloroethane is used as so-called stain water for individual treatment, but also for detaching textiles in dry cleaning.
  • the color pigments in dyed fibers can be attacked by such a solvent, so that, in addition to the removal of stains, the treated area is also discolored or discolored.
  • a particular disadvantage of the use of such solvents, which are all highly volatile, is that sufficient treatment time is not possible in the treatment of stains, so that, for example, in the case of a color stain with a binder, such as a paint stain or a ballpoint pen stain, the binder is dissolved
  • the pigment particles adhering to the fiber cannot be completely separated from the fiber, so that a residual discoloration remains.
  • Another problem here is edge-free stain removal, which would only be possible if the textile piece in question was completely immersed in the solvent.
  • the object of the invention is to create a method for removing stains which, due to the means chosen, enables long exposure times and edge-free stain removal.
  • the soiled area in at least a first stain removal component, comprising a mixture of glycolic acid n-butyl ester, dietylene glycol mono-n-butyl ether and fatty amine derivative with betaine structure and / or a second stain removal component, comprising a mixture of Acetic acid (diethylene glycol mono-n-butyl ether) ester, and a mixture of at least one nonionic surfactant and at least one emulsifiable surfactant, which contains an amine as cation, soaked and after a predeterminable exposure time the soaked area is additionally soaked with a small amount of water, drummed and then washed out with water.
  • a first stain removal component comprising a mixture of glycolic acid n-butyl ester, dietylene glycol mono-n-butyl ether and fatty amine derivative with betaine structure
  • a second stain removal component comprising a mixture of Acetic acid (diethylene glycol mono-n-
  • Both stain remover components are non-toxic, practically non-volatile and water-soluble. It has been shown that, depending on the type of staining substance, treatment of the stained area with only one stain remover component is sufficient, but that the use of both components is necessary for the treatment of stains which have not hitherto been removed. For example, it is sufficient to soak stains from fruit juices only with the first stain remover component and, after an exposure time of around 10 to 15 minutes, mechanically rub or walk with the addition of a small amount of water and then wash the soaked area with water. Paint stains can be removed in a variety of cases by treatment with the second stain removing component as described above.
  • stains caused by ballpoint or felt pens or by so-called marker pens must be treated by first soaking the stained area for several hours depending on the degree of soiling, then adding the second stain remover component to the first stain remover component , so that both components can act on the contamination over a further exposure time of, for example, 10 minutes to an hour.
  • the fabric is then mechanically processed with the addition of a little water, for example tumbled or rubbed against one another, and the impregnation consisting of the two stain-removing components and water is then rinsed out.
  • the agents according to the invention do not have to be labeled with regard to flammability, since the flash point of the first component is 75 ° C. and the second Component is 108 ° C. It is also advantageous that the solvent content of both components in the MAK values cm 3 / m 3 (ppm) and mg / m 3 air are not listed in the characteristic value tables with regard to the indoor air pollution and therefore the use in closed rooms is possible.
  • the second stain remover component for carrying out the process preferably consists of a mixture of coconut fatty acid monoethanolamide with 4.5-6 moles of ethylene oxide adducts, 97-98% dodecylbenzenesulfonic acid, pure triethanolamine, acetic acid (diethylene glycol mono-n-butyl ether) ester.
  • the two constituents dodecylbenzenesulfonic acid and triethanolamine are used as a water-containing mixture, the water content preferably being 9.8%.
  • this emulsifiable surfactant can also be formed by triethanolamine alkyl sulfate,
  • the amines specified in claim 6 can optionally be used.
  • the anionic part of the surfactants can optionally consist individually or in a corresponding mixture of fatty alkyl sulfuric acid ester or fatty acids. They can also be used as salts, in which case these compounds can also be used as water-containing compounds.
  • anionic surfactants in the form of their free acid such as, for example, fatty acids, in particular dodecylbenzenesulfonic acid, can be prepared and used in situ with the amines specified in claim 6.
  • the advantage of the two stain remover components is that only the soiled area in a flat dish needs to be soaked for stain removal, a longer exposure time of several hours being possible, since both stain remover components are practically non-volatile.
  • the selection of whether the first or the second stain remover component is used alone or in cooperation with one another essentially depends on the substance causing the stain.
  • the order of application also depends essentially on the substance causing the stain.
  • the impregnation is first carried out with the first stain remover component, then the second stain remover component is added and, after a short exposure time, a little water is added, and after a further exposure time, the impregnation with water is completely washed out with mechanical flexing or rubbing the soiled area.
