Definitions
- the present invention describes means and methods for washing laundry items which contain foam-forming components.
- washing laundry In the field of commercial laundries, detergents are used that contain the usual washing aids such as alkali dispensers, complexing agents and surfactants.
- the detergents are used either in discontinuous or continuous machines.
- the machines to be operated continuously have a large number of washing chambers arranged one behind the other, so that the items to be cleaned are continuously transported from washing chamber to washing chamber during the washing process, while usually the washing medium, which consists of the aqueous solution of the detergent and the impurities introduced, is carried in countercurrent to the transported laundry.
- the discontinuous machines generally consist of a single washing chamber, which is provided with a washing drum perforated in the wall to hold the laundry.
- the items to be washed are first treated in the above-mentioned washing medium and then rinsed several times with fresh washing medium.
- the means and methods have a number of disadvantages when it comes to washing laundry goods which contain foaming components.
- the invention has for its object to provide a detergent and a method that is suitable for washing laundry containing foam-forming substances, without the foam development is increased during the washing process.
- the invention is also based on the object of providing a detergent and a method which, in particular in the case of items heavily soiled with pigments, contribute to the fact that the items to be washed maintain good quality even after several cycles of soiling and washing and increase the service life becomes.
- the invention is further based on the object of providing a detergent and a method which is equipped in such a way that the laundry items have an at least 10% higher number of life cycles which include the use, washing and drying of the laundry items normal detergents before they are mechanically destroyed.
- the object of the present invention is to use detergents and processes, in contrast to the prior art listed above, for machine washing laundry goods which contain foam-forming substances and to equip the detergents in such a way that they do not intensify the development of foam during the washing process.
- the proportion of surfactant, based on the total amount of the detergent is less than 6% by weight, preferably less than 3% by weight and in particular less than 1.5% by weight, and in the special case no surfactant is present at all .

- the visual appearance of the laundry is improved by using graying inhibitors in concentrations of 0.1-5% by weight, preferably 0.5 to 3% by weight, based on the total detergent.
- the detergent can contain one or more constituents from the group of builder substances as softeners and / or alkali donors, bleaches, brighteners, biocides, 10 to 60% by weight softener, 5 to 40% by weight, based on the total amount of the detergent.
- % Alkali dispenser 5 to 30% by weight bleach, 0.1 to 10% by weight brightener, 0.1 to 10% by weight, biocides, preferably 20 to 50% by weight softener, 10 to 20% by weight.
- -% alkali dispenser, 10 to 20 wt .-% bleach, 0.5 to 5 wt .-% brightener, 0.3 to 5 wt .-% biocides can be included.
- Another object of the invention is a method for using the agents according to the invention for washing detergent contaminated with surface-active substances by treating the laundry detergent with a detergent solution which can be obtained by dissolving or dispersing the detergent according to the invention in water the process is carried out at temperatures of the washing medium between 30 ° C. and 90 ° C., preferably between 40 and 70 ° C., and the washing process is preferably carried out with the aid of mechanical processing.
- laundry items which, due to their intended use, contain surface-active substances and also a high level of contamination are mops, flat mop covers, window wipers or cleaning cloths.
- a further form of the method according to the invention consists in the optimal interaction of the dirt components in the laundry and the ingredients in the detergent in order to achieve an optimal result with regard to cleaning performance, course of the washing process and environmental entry of surface-active substances.
- the process can be carried out, for example, in such a way that soiled surfaces are cleaned with materials provided for this purpose, which have been conditioned with detergents containing surface-active substances and, after the cleaning process, the then contaminated materials containing surface-active substances as laundry items with a detergent solution, which is obtained by dissolving or dispersing a Detergent according to the invention treated in water in the manner as described in the inventive method.
- laundry items that are suitable for such a procedure are mops, flat mop covers, window wipers or cleaning cloths.
- the cleaning agents are, for example, cleaning agents containing surface-active substances for solid surfaces.
- the detergents according to the invention can contain surfactants in a limited concentration. If surfactants are used in the detergents according to the invention, then preferably low-foam nonionic surfactants such as, for example, C 2 -C 8 alkylpolyethylene glycol polypropylene glycol ether, each with up to 8 moles of ethylene oxide and propylene oxide units in the molecule.
- surfactants such as, for example, C 2 -C 8 alkylpolyethylene glycol polypropylene glycol ether, each with up to 8 moles of ethylene oxide and propylene oxide units in the molecule.
- nonionic surfactants known as low-foaming can also be used, such as, for example, C 2 -C 8 -alkylpolyethylene glycol polybutylene glycol ether, each with up to 8 moles of ethylene oxide and butylene oxide units in the molecule, and also end group-capped alkyl polyalkylene glycol mixed ethers.
- the builder substance contained in the cleaning agents according to the invention can in principle be any substance which is known in the prior art as a builder suitable in the broadest sense for detergents and cleaning agents; builder substances are preferably used.
- the coated builder substances known in the prior art can also be used and are even preferred when working with chlorine-containing bleaching agents.
- B. alkali phosphates which may be in the form of their sodium or potassium salts, in question.
- Examples include: tetrasodium diphosphate, pentasodium triphosphate, so-called sodium hexa- metaphosphate and the corresponding potassium salts or mixtures of sodium hexametaphosphate and the corresponding potassium salts or mixtures of sodium and potassium salts.
- complexing agents are to be mentioned, such as. B. nitrilotriacetate or ethylenediaminetetraacetate. Soda and borax are also among the builder substances in the context of the present invention.
- water-soluble builder components are e.g. B. organic polymers of native or synthetic origin, especially polycarboxylates.
- polyacrylic acids and copolymers of maleic anhydride and acrylic acid and the sodium salts of these polymer acids are suitable.
- Commercial products are e.g. B. Sokalan® CP 5 and PA 30 from BASF, Alcosperse® 175 and 177 from AIco, LMW® 45 N and SP02 ND from Norsohaas.

- hydroxy carboxylic acids such as. B. mono-, dihydroxy-succinic acid, ⁇ -hydroxypropionic acid, citric acid, gluconic acid, and their salts. Citrates are preferably used in the form of trisodium citrate dihydrate.
- Amorphous metasilicates or layered silicates can also be mentioned as builder substances.
- Crystalline layered silicates are also suitable builders insofar as they are sufficiently stable to alkali; Crystalline layered silicates are sold by Hoechst AG (Germany) under the trade name Na-SKS, e.g. B. Na-SKS-1
- Na-SKS-2 Na 2 Si ⁇ 4 0 29 xH 2 0, magadiite
- Na-SKS-3 Na 2 Si ⁇ 4 0 29 xH 2 0, magadiite

- Particularly preferred builder substances are those selected from the group consisting of pentasodium triphosphate, trisodium citrate, nitrilotriacetate, ethylenediaminetetraacetate and mixtures thereof.
- methylylyvine diacetate or alkali salts of phosphonic acids such as 1-hydroxyethane-1, 1-diphosphonate, diethylenetriamine pentamethylene phosphonate or ethylenediaminetetramethylene phosphonate in question.
- the graying inhibitors contained in the detergent according to the invention have the task of keeping the dirt detached from the fiber suspended in the liquor and thus preventing the dirt from being re-absorbed.
- Water-soluble colloids of mostly organic nature are suitable for this, for example the water-soluble salts of polymeric carboxylic acids, glue, gelatin, salts of ether carboxylic acids or ether sulfonic acids of starch or cellulose or salts of acidic sulfuric acid esters of cellulose or starch.
- Water-soluble polyamides containing acidic groups are also suitable for this purpose. Soluble starch preparations and starch products other than those mentioned above can also be used, e.g. degraded starch, aldehyde starches, etc. Polyvinylpyrrolidone can also be used.
- cellulose ethers such as carboxymethyl cellulose (sodium salt), methyl cellulose, hydroxyalkyl cellulose and mixed ethers such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and their mixtures and polyvinylpyrrolidone, for example in amounts of 0.1 to 5% by weight, based on the composition, are preferably used .
- Bleaches such as. B sodium perborate also in the form of its hydrates, or sodium percarbonate, or from the group of chlorine-based bleaches, such as N- Chlorine-p-toluenesulfonic acid amide, trichloroisocyanuric acid, alkali dichloroisocyanurate, alkali hypochlorites, and alkali hypochlorite releasing agents, with alkali-stable bleaching agent compositions being particularly preferred.
- These can be both alkali-stable substances or components stabilized by suitable processes such as surface coating or passivation.
- brighteners e.g. Salts of 4,4'-bis (2-anilino-4-morpholino-1, 3,5-triazinyl-6-amino) stilbene-2,2'-disulfonic acid or compounds of similar structure which, instead of the morpholino group, have a diethanolamino group , a methylamino group, an anilino group or a 2-methoxyethylamino group.
- brighteners of the substituted diphenylstyryl type may be present, e.g.
- halogen-containing substances such as dichloroisocyanurate or other halogen releasers such as chloramine T or bromohydantoins or triclosan are preferred.
- halogen-containing substances such as dichloroisocyanurate or other halogen releasers such as chloramine T or bromohydantoins or triclosan are preferred.
- other common biocides such as aldehydes, amines or others can also be used.
- the amount of surfactant in the detergent By reducing the amount of surfactant in the detergent, the amount of surfactant in the washing medium can be reduced, and as a result, the foam development is not increased during the washing process and, moreover, a better cleaning result is achieved.
- the lower proportion of surfactant in the washing medium also means that the wastewater is less polluted. Additional advantages come to light when it comes to washing items that are used to clean surfaces before washing. It is observed that the higher proportion of complexing agents in the product when washing contaminated mops and flat mop covers can reduce the proportion of incrusting contaminants remaining after the washing process and subsequent drying. This makes it possible to prevent the laundry from being destroyed prematurely and thereby increase the number of use cycles.
- Laundry items the intended use of which is cleaning the surface, are usually contaminated with a high level of dirt when contaminated. As a result, a graying effect can be observed after only a few application and washing cycles.
- the proportions of graying inhibitors used in conventional heavy-duty detergents are not sufficient to counteract the graying.
- An advantage of the methods and agents according to the invention is that the graying effect is counteracted by increasing the proportion of graying inhibitors.
- the covers were washed alternately and used in practice. They were numbered and could always be subjected to the same conditions.
- the laundry was examined with regard to its visual appearance in order to be able to determine differences in appearance.
- the whiteness of the covers after the 30th washing process was also determined photometrically.
- the degree of whiteness is measured with the reflectance color measuring device Minolta CR 200, which is coupled to a PC, which processes the measured values further.
- Minolta CR 200 which is coupled to a PC, which processes the measured values further.
- MgO plate 100% reflection.
- the reflection values also document that recipes A and B are superior to recipe C.
