Definitions

  • substrates whose adsorption capacity is below this range release the usual active substances too quickly, so that the active substances are transferred unevenly to the laundry and the treated laundry becomes stained.
  • the adsorption capacity is above the required range, too little active ingredient should be released from the substrate into the laundry.
  • suitable absorbent papers, sponges and woven cloths or nonwovens are designated as suitable substrates.
  • Special plasticizers and plasticizer combinations are also known, which can be combined with flexible substrates, to which the adsorption capacity does not impose any requirements that are just as limited as in DE-B-1965470.
  • DE-A-27 00 512 describes a mixture of a conventional cationic fabric softener and a fatty acid ester of a polyhydric alcohol in a certain mixing ratio. From DE-A-27 00 560 an agent is known which contains a fatty alkyl polyglycerol ester as a fabric softener. Further references on laundry aftertreatment agents, which essentially consist of substrates with a practically unlimited adsorption capacity and special plasticizers, are DE-A-25 46 505, 26 25 774, 25 16 104, 26 36 787, 25 56 248, 25 37 402 and the US-A-4 073 996, 4 049 858, 4 096 071, 4142978, 4110 498.
  • laundry post-treatments consist of substrates with very low adsorption capacity, which with a Coating are provided from conventional textile softening compounds.
  • These customary textile-softening compounds are quaternary ammonium compounds derived from ammonia or imidazoline, which can be used up to 80% by weight by condensation products of a fatty acid triglyceride and hydroxyalkyl polyamine.
  • the agents of the European patent application mentioned when used in the tumble dryer with good softening performance, do not lead to the formation of stains on the laundry, although this should have been the case according to the teaching of DE-B-19 65 470.
  • a textile treatment agent consisting essentially of a water-insoluble substrate and a mixture of quaternary ammonium compounds and a dispersion inhibitor is known from US Pat. No. 4,118,525.
  • This textile treatment agent is added to the textiles to be treated during washing in the wash liquor and, together with the textiles, placed in a tumble dryer after washing. It is there that the textile treatment agent releases the plasticizer to the textiles after premature release in the wash liquor has been prevented by the dispersion inhibitor, which is not itself a plasticizing agent.
  • an agent for the aftertreatment of washed laundry in a tumble dryer consisting essentially of a flexible textile fabric which is provided with a coating which contains a softening and antistatic quaternary ammonium compound and optionally auxiliaries and fragrances, which thereby is characterized in that the fabric has an adsorption capacity of 1.0 to 4.5 and a fabric, fleece or foam-like structure made of polyester, polyamide, polyolefin, polyacrylonitrile, polyurethane or viscose and mixtures thereof and the coating has a soft and antistatic agent or an active ingredient mixture of quaternary ammonium compounds derived from ammonia or imidazoline, which can be replaced up to 80% by weight with condensation products from a fatty acid triglyceride and hydroxyalkyl polyamine, and 0.2 to 5% by weight aliphatic hydroxycarboxylic acids with a molecular weight of up to about 250 or phosphons Acids and optionally 0.05 to 1 wt .
  • Nonwoven structured fabrics are preferred in the context of the present invention. They are produced in a manner known per se by air, water separation or mechanically, by laying thermoplastic or non-thermoplastic fibers cut to a desired length, preferably in a confused manner, for the formation of nonwovens, and these by a binder or by the action of temperature (in the case of the use of thermoplastic fibers) with one another glued. A distinction is made between binder-bound and melt fiber-bonded nonwovens.
  • Suitable nonwovens have a size of 0.01 to 0.2 m 2 and a weight per unit area of between about 10 and 100 g per m 2 .
  • the adsorption capacity is measured according to a modified test (US Federal Specifications UU-T-595 b) with changes as described in DE-B-19 65 470 and explained in more detail in the example part of EP-A-33 134.
  • a preferred fiber material for the suitable nonwovens consists of the thermoplastic polymers polyolefin, polyester, polyamide, polyacrylonitrile.
  • the following nonwovens are particularly distinguished from the series of suitable nonwovens: nonwovens made from binder-bound thermoplastic fibers, in particular from polyester, furthermore from binder- and / or protective fiber-bound viscose fibers and / or thermoplastic fibers, of which nonwovens made from mixtures of binder-bound thermoplastic fibers and viscose exist, are preferred; Also particularly suitable and therefore preferred are binder-bound nonwovens made from viscose fibers.
  • a commercially available fleece which is excellently suitable for the agents according to the invention consists, for example, of polyester fibers.
  • a suitable nonwoven is a nonwoven made from viscose fibers. It has a basis weight of approximately 55 g per m 2 and an adsorption capacity of approximately 3.5.

  • Another suitable nonwoven consists of polypropylene fibers. It has a weight per unit area of approximately 50 g per m 2 and an adsorption capacity of approximately 2.0.
  • Another nonwoven made of polypropylene fibers has a weight per unit area of approximately 35 g per m 2 and an adsorption capacity of 2.8. Similar results to those obtained with nonwovens are also obtained with a polyacrylonitrile fiber fabric that has an adsorption capacity of 1.7.
  • Other suitable substrates are polyurethane foams with an adsorption capacity of 3.7 to 4.2.
  • Foam sheets made of polyethylene and polypropylene are also suitable substrates.
  • Suitable quaternary ammonium compounds are, in particular, those with two long-chain, preferably saturated aliphatic radicals each having 14 to 26, in particular essentially 16 to 20, carbon atoms and at least one quaternary nitrogen atom in the molecule.

  • quaternary ammonium compounds are, in particular, derivatives of ammonia, that is to say the quaternary salts obtainable by alkylation of long-chain secondary amines, such as, for example, the compounds distearyldimethylammonium chloride or ditalgalkyldimethylammonium chloride or methosulfate.
  • Other suitable quaternary ammonium compounds are the imidazoline compounds obtainable by reacting 1 mol of a Aminoalkylethylendiamins Hydroxyalkylethylendiamins or with 2 moles of a long-chain C, 2 W 7C fatty acid or its esters, which are then converted by alkylation in the quaternary imidazolinium compounds.
  • the anion generally consists of the acid residue which has arisen from the alkylating agent used in the quaternization.
  • chloride, bromide, methyl sulfate, ethyl sulfate, methane, ethane or toluenesulfonate are therefore suitable as anions.
  • the quaternary ammonium compounds are also good antistatic agents.
  • Some of the quaternary ammonium compounds can be replaced by other compounds, for example by the condensation products, also known as fabric softeners, of 1 to 3 moles of fatty acid or fatty acid alkyl ester and 1/3 to 1 mole of fatty acid triglyceride with one mole of a hydroxyalkylpolyamine, for example hydroxyethylethylenediamine, hydroxyethyldiethylenetriamine.

  • these are acids from the group comprising the compounds malic acid, tartaric acid, tartronic acid, lactic acid, glycolic acid, citric acid and mixtures thereof, of which lactic acid, glycolic acid and especially citric acid and mixtures thereof are preferred.
  • the agents can also have the same advantage of phosphonic acids, for example 1-hydroxyethane-1,1-diphosphonic acid, aminotris- (methyl-enphosphonic acid), 2-phosphonobutane-1,2,4-tricarboxylic acid or ethylenediamine tetrakis (me - contain ethylene phosphonic acid).
  • phosphonic acids for example 1-hydroxyethane-1,1-diphosphonic acid, aminotris- (methyl-enphosphonic acid), 2-phosphonobutane-1,2,4-tricarboxylic acid or ethylenediamine tetrakis (me - contain ethylene phosphonic acid).
  • brighteners for cotton are used as optical brighteners. These are primarily derivatives of diaminostilbenedisulfonic acid or its alkali metal salts.
  • compositions contain 0.2 to 5% by weight of the above-mentioned hydroxycarboxylic acids or phosphonic acids and optionally 0.05 to 1% by weight of optical brighteners, in each case based on the amount of softening and antistatic agent.
  • Non-ionic dispersants are particularly suitable as auxiliaries.
  • antimicrobials, soil release substances, ironing aids and impregnating agents can also be present.
  • Suitable nonionic dispersants are primarily addition products of 4 to 40, preferably 4 to 20, moles of ethylene oxide to 1 mole of an aliphatic C 1D- C 20 alcohol or an alkylphenol in which the alkyl radical has 8 to 18 carbon atoms, and fatty acids and alkylamines of 10 to 20 carbon atoms.
  • the ethoxylation products of the fatty alcohols in particular the coconut and tallow fatty alcohols and the oleyl alcohol, and the ethoxylation products of the oxo alcohols and secondary alcohols of the corresponding chain lengths are particularly preferred.
  • nonionic surfactants are the water-soluble 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups containing adducts of ethylene oxide with polypropylene glycol or with alkylenediamine polypropylene glycol or with alkyl polypropylene glycols with 1 to 10 carbon atoms, in which the polypropylene glycol chain acts as a hydrophobic residue. All of these compounds, in proportions of 5 to 60% by weight of the coating, bring about an even distribution of the active substances and fragrances in the preparation and use of the agents according to the invention.
  • Quaternary ammonium compounds can also be used as antimicrobial active substances, that is to say bactericidal or bacteriostatic or fungicidal or fungistatic compounds, in particular those which, in addition to a long-chain aliphatic and two short-chain aliphatic hydrocarbon radicals, have an aromatic double compound which is linked to the nitrogen atom via an aliphatic hydrocarbon atom or an aliphatic double compound organic residue contained in the molecule.
  • Typical representatives for such antimicrobial agents are the compounds dimethylbenzylhexyl-allyldodecylammonium chloride.
  • Antimicrobial agents which can be used are also the bromo-nitro alcohols, for example the compounds 2-bromo-2-nitropropane-1,3-diol, 1-bromo-1-nitro-3,3-trichloro-2-propanol, 2-bromo-2- nitrobutanol.
  • halogenated and / or trifluoromethyl-substituted phenolic compounds are halogenated and / or trifluoromethyl-substituted phenolic compounds, in particular the halogenated salicylanilides, for example the compounds dibromo and tribromosalicyl anilide and derivatives of phenoxyphenol, such as the compound 2-hydroxy-2 ', 4,4'-trichloride - phenyl ether.
  • Compounds which improve the dirt-removing ability during washing are suitable as active ingredients for soil release finishing for textiles. These include compounds of the polyacrylic polyvinyl alcohol type, modified fluorocarbons and hydrophilic polymers. Polyvinyl acetates, paraffins, but also borax are suitable additives that make ironing the laundry easier.
  • the agents according to the invention are produced by impregnating a piece of the substrate with the mixture of textile-softening active ingredient, low molecular weight hydroxycarboxylic acid, to which optical brighteners and / or auxiliaries and fragrances have been added, in such an amount that the substrate is used for the treatment a laundry item in the automatic tumble dryer has sufficient active ingredient impregnation.
