Definitions

  • the invention relates to a laundry aftertreatment agent serving in particular as an ironing aid.
  • aqueous dispersion of a water-insoluble lubricant in particular a silicone oil
  • a water-soluble film former in particular a water-soluble starch derivative
  • This dispersion is sprayed onto the laundry to be ironed and enables the iron to slide more easily than an untreated laundry, the film former imparting a certain stiffness to the ironed laundry, which is particularly desirable for shirts and blouses.
  • Spraying the laundry using a spray can is expensive, however, and is therefore mainly limited to use with shirts and blouses.
  • the sliding effect achieved with the known dispersion described above is still not entirely satisfactory. It is also difficult to spray the tissue evenly without completely soaking it. This can lead to undesirable stains or margins on the fabric.
  • Another disadvantage is that the spray can often cannot be completely emptied despite an elaborate spray mechanism.
  • the object of the invention is therefore to provide a laundry aftertreatment agent for facilitating ironing which, in comparison to the known ironing aid described above, permits even easier ironing due to an increased sliding action and is less expensive to use.
  • the laundry aftertreatment agent according to the invention not only results in a higher sliding effect than the known ironing aid described above, but also increases the absorbency of the fabric against water and gives the fabric a soft, fluffy feel, while also giving the ironed laundry a slight finish.
  • This effect of the laundry aftertreatment agent according to the invention is surprising insofar as it has hitherto been considered impossible to achieve the combination of the properties described above, in particular the combination of a fluffy feel with the absorbency of the fabric against water.
  • so-called fabric softeners which contain quaternary ammonium bases with long-chain alkyl residues as active ingredients, have hitherto been used as laundry after-treatment agents.
  • the laundry aftertreatment agent according to the invention is therefore not only an improved ironing aid compared to the known ironing aid, but at the same time a means by which the body and the feel of the laundry are improved while at the same time achieving a softening effect, without thereby impairing the absorbency of the treated laundry becomes.
  • the laundry aftertreatment agent according to the invention enables ironing of dry laundry, an even better sliding effect being achieved compared to moistened laundry. It is only necessary to slightly dampen the laundry if there are persistent creases.
  • steam irons As is known, a steam iron cannot be used for ironing laundry which has been treated with the known ironing aid described above.
  • DE-OS 26 31 419 describes a laundry treatment agent which can also be introduced into the last rinse cycle of a washing machine and which has the use of a silicone oil in common with the laundry treatment agent according to the invention, but in the known case no alkoxylated starches and celluloses are used, when used according to the invention, not only the bulk and the lubricity, but also the absorbency of the treated tissues are surprisingly increased. In the known case, roasted dextrins are used which only act as thickeners.
  • fatty acid amides are used in contrast to the use of fatty acid amines in the known case. These require less dirt reduction and are easier to hydrolyze than amines and are therefore easier to wash out. In addition, they are more easily degradable and therefore more environmentally friendly than the amines used in the known case.
  • the cationically dispersed silicone oil (component A) is a textile-relevant silicone oil with a viscosity between 500 and 50,000 mm , - S - 1 at 25 ° C, in particular 1000 to 10,000 mm , - s -1 at 25 ° C, as it is described, for example, in “Textilveredelung”, 19 (1984) No. 5 on pages 144 and 145.
  • alkyl silicone oils very particularly methyl silicone oil with a viscosity of 1000 to 10,000 mm 2 ⁇ S - 1 , are suitable.
  • the laundry aftertreatment agent according to the invention can preferably also contain a paraffin wax as a partial replacement for the silicone oil, which preferably has a melting point ⁇ 40 ° C. and in particular from 50 to 60 ° C.
  • This quaternary siloxane which can be referred to as a polysiloxane-dimethylalkylammonium acetate copolymer, preferably has a density at 20 ° C. of 1.053 g / cm 3 and a viscosity at 20 ° C. of 60 to 100 mPa ⁇ s in a 30% aqueous solution , while the pH of a 30% solution is 6 to 7.
  • silicone oil of component A) can consist of a silicone elastomer, as described in “Textilpraxis International” (1983), December, on pages 1342 and 1343.
  • a component of the substances mentioned can also be used as component A).
  • stearic acid or oleic acid are suitable as monocarboxylic acids and diethylenetriamine and diethylenetriamineethanolamine as polyamines.
  • Component C) is a cationic alkoxylated starch, as described for example in DE-PS 21 55941, or a cationic alkoxylated cellulose.
  • the alkoxy content is preferably between 4 and 10% and the nitrogen content between 0.1 and 0.5%.
  • the cationic dispersant for the silicone oil of component A) can be any cationic emulsifier.
  • a cation-active imidazolinium salt in particular a compound of the formula, is particularly preferred in which R 3 is a long-chain hydrocarbon radical which may be saturated or unsaturated and in particular has 10 or more carbon atoms, R 4 is hydrogen or an alkyl radical, in particular having 1 to 5 carbon atoms, the alkyl radical being substituted and in particular having a hydroxy radical at its end , means R 5 is a lower alkyl radical, in particular a C 1 -C 4 - Is alkyl radical, X is an anionic radical, preferably a halide radical, or an anionic group, in particular the group wherein R 6 represents a C 1 -C 4 alkyl group, or is the acetate group.
  • the cationic dispersant is preferably used in an amount of 2 to 10% based on the silicone content.
  • Component A) also contains an alkoxylated, in particular ethoxylated, fatty amine in an amount of up to 10% by weight, based on the silicone content.
  • the laundry aftertreatment agent according to the invention preferably contains component A) in an amount of 0.5 to 20% by weight, in particular 3 to 8% by weight, component B) in an amount of 0.5 to 15% by weight, in particular 2 to 8% by weight, and component C) in an amount of 1 to 15% by weight, in particular 2.5 to 7.5% by weight (balance water).
  • the laundry aftertreatment agent according to the invention preferably contains fragrances, preservatives, dyes and organic acids, in particular organic aliphatic carboxylic acids, such as acetic acid or citric acid, for setting a pH of preferably 3 to 5.
  • the components of the laundry aftertreatment agent according to the invention are distinguished by a relatively high substantivity to the textile fiber, i.e. they are drawn from a cold and long liquor, in particular onto cotton, so that the laundry aftertreatment agent according to the invention is particularly suitable for treating laundry consisting of cotton or laundry containing a proportion of cotton.
  • the laundry aftertreatment agent according to the invention does not cause increased re-soiling of the treated laundry, and likewise does not promote laundry yellowing, which can occur in the case of conventional softeners.
  • the laundry aftertreatment agent according to the invention is expediently added to the last rinse after the washing process in an amount of 50 to 80 grams, the water volume of the last rinse being about 20 liters.
  • the laundry aftertreatment agent according to the invention can be produced by the following two methods:
  • Cation-active alkoxylated starch is dispersed in water. This dispersion is heated to 80 to 90 ° C. with vigorous stirring, a moderately viscous solution being formed. The mixture is then cooled to 20 to 25 ° C and the solution is mixed with the cationic fatty acid condensation product, dispersed in water. As soon as a uniform dispersion has been obtained, the silicone oil dispersion dispersed with a cationic disperser is carefully added with slow and vigorous stirring. The dispersion is adjusted to an acidic pH using an acid. Finally, color, fragrance and a preservative are added.
  • the starch solution is prepared in the manner described above.
  • the cationic fatty acid condensation product in pure solid form is added to the solution heated to 90 ° C. with vigorous stirring. The mixture is stirred until a stable dispersion has formed. Then it is cooled to 20 to 25 ° C and proceed as described above.
  • the pH of this agent is 4. It is a thin, milky-looking dispersion and with a viscosity of 120 mPa - s.
  • This agent 82.35 parts by weight
  • the pH of this agent is 3 to 4. It is a thin, milky-looking dispersion with a viscosity of 80 mPa 's.
  • Example 2 Using the agent produced in Example 2, which is added to the last rinse of a conventional household washing machine in an amount of 50 to 80 g, laundry items made of cotton and cotton / polyester blended fabrics, which were previously washed using a conventional detergent at 95 ° C. were. treated to determine the ironing values.
  • the prick test is carried out as follows:
  • the ironing values for the untreated fabric fluctuate around the mean values given in the table by + 10%. This applies in particular to the sliding values. The cause is to be found in the non-uniformity of the surface roughness of the fabric.
  • the significantly lower ironing values determined with "ironing aid" and the agent according to the invention have a significantly smaller fluctuation range (maximum 5%), since the reproducibility is improved because of the decreasing surface roughness of the treated tissue.
  • Laundry samples made from 100% cotton fabric are washed 5 or 6 times at 95 ° C. and 60 ° C. using a conventional detergent and aftertreated in an amount of 80 g in each case in the last rinse cycle by adding the laundry aftertreatment agent according to Example 2.
  • the ironing value that surprisingly deviates only slightly from the smoothness value of the first aftertreatment already arises with the first repetition of the aftertreatment.
  • the laundry aftertreatment agent according to the invention can be washed out of the laundry sample both when washing at 95 ° C. and when washing at 60 ° C. There are therefore no disadvantageous addition effects when using the laundry aftertreatment agent according to the invention.
  • Terry towels (100% cotton) are washed in a conventional manner and in the last rinse once with the agent of Example 2 in a concentration of 50 to 80 g / 20 liters and once for comparison with a conventional fabric softener (based on distearyldimethylammonium chloride) treated with the same concentration. Untreated terry towels are also used for comparison purposes. A total of 15 terry towels are washed twice at 60 ° C. After air drying The terry towels of the three test groups are placed on top of one another in a stack on a drying rack. The stack heights are determined after 10 minutes and the results are shown in Table 11.
  • the height of the stack is a measure of the bulkiness of the terry towels and the loosening of the individual fibers.
  • the agent according to the invention surprisingly brings about an even greater stack height than the known plasticizer.
  • the absorbency is a measure of the absorption capacity of moisture from textile fabrics (terry cloth).
  • the absorbency is determined using the rising height method according to DIN 53294.
  • the 3 cm wide and 25 cm long cotton strips (100% cotton fabric, not equipped, with a basis weight of 140 g / cm 2 ) are immersed with one end in distilled water, which due to the capillary forces in the fabric more or less depending on the absorbency rises high.
  • the climbing heights after a test period of 5 minutes are shown in Table III.
