Definitions

• the invention relates to wetting agents for textile pretreatment which contain selected mixed ethers, and to the use of the mixed ethers for producing wetting agents for textile pretreatment.
• wetting agents are used, the tasks of which include, for example, supporting the detachment of impurities from the fibers or bleaching.
• Extensive requirements are placed on tools of this type. For example, they must be chemically stable under the often strongly alkaline conditions, have a wetting time in the range of seconds, do not provide their own foam, suppress process foam and, in addition, be easily biodegradable.
• EP-A 0 124 815 (Henkel) mixed ethers with 8 to 18 carbon atoms in the fatty alkyl and 7 to 12 ethylene oxide units in the polyether chain are known as foam-suppressing additives to low-foam cleaning agents.
• EP-B 0 303 928 (Henkel) proposes octyl and / or decyl mixed ethers with 3 to 4 ethylene oxide units.
• EP-A 0 420 802 (Ciba-Geigy) proposes wetting agents for textile pretreatment which contain fatty alcohol polyglycol ethers which are open-chain and / or end-capped.
• Suitable feedstocks which have a fatty alkyl radical of at least 8, preferably 9 to 14 carbon atoms and 2 to 24, preferably 4 to 8 alkylene oxide units in the polyether chain; they can be open-chain or end-capped with a C 1 -C 8 alkyl group, a cycloaliphatic radical with at least 5 carbon atoms and a phenyl-lower alkyl or styryl radical.
• an open-chain adduct of 15 mol of alkylene oxide with a C 9 -C 11 oxo alcohol is disclosed.
• the object of the invention was therefore to develop new wetting agents which are simultaneously low-foaming, foam-reducing, rapidly wetting, alkali-resistant and readily biodegradable.
• the invention relates to wetting agents for textile pretreatment containing mixed ethers of the formula (I),
• R 1 O- (CH 2 CHO) m (CH 2 CH 2 O) n -R 2 (I) in which R 1 is a strictly linear alkyl radical having 8 to 10 carbon atoms, R 2 is an alkyl radical having 1 to 4 carbon atoms, m is a number from 0.5 to 2 and n is a number from 6 to 9.
• the present examples and comparative examples show that even a slight modification of the length of the fatty alkyl chain or of the degree of ethoxylation causes a significant deterioration in the wetting and foaming power, while an increase in the propylene glycol content or the introduction of branches into the fatty alkyl radical reduce the biodegradability of the products and their foam-suppressing properties Effect drastically worsened.
• Mixed ethers are known substances that can be obtained by the relevant methods of preparative organic chemistry. They are usually produced using the WILLIAMSON ether synthesis method, in which fatty alcohol polyglycol ethers are used in the presence of strong bases Alkyl halides condensed. Methods for their preparation are for example from the publications DE-OS 28 00 710 (Kuraray) and DE-C1 37 44 525 (Henkel). An overview by Piorr et al. on the subject of "mixed ether” can also be found in Fat Sci.Technol. 89, 106 (1987).
• mixed ethers which are suitable as constituents of the wetting agents according to the invention are methyl, ethyl or butyl end group capped adducts of 0.5 to 2 mol of propylene oxide and 6 to 9 mol of ethylene oxide with octanol and / or decanol.
• a mixed ether is to be emphasized, which is accessible by the addition of first 1.2 moles of propylene oxide and then 6 or 7 moles of ethylene oxide to octanol and subsequent end group sealing with butyl chloride.
• the wetting agents according to the invention can contain the mixed ethers of the formula (I) in amounts of 5 to 90, preferably 50 to 85% by weight, based on the agents. Furthermore the agents according to the invention can contain further conventional additives, in particular hydrotropes and solvents.
• Hydrotropes a1) Linear or branched, aliphatic alcohols having 4 to 8 carbon atoms are suitable as hydrotropes. Typical examples are ethanol, propanol, butanol, pentanol, capro alcohol and 2-ethylhexanol. a2) Cycloaliphatic alcohols of the terpenol type, such as, for example, geraniol, dihydroterpinol, nopol, myrcenol and terpineol, can also be taken into account as further hydrotropes.
• hydrotropes are aromatic alcohols such as, for example, benzyl alcohol, phenylethanol, phenoxyethanol, 1-phenoxy-2-propanol (phenoxyisopropyl alcohol) and cinnamon alcohol.
• aromatic alcohols such as, for example, benzyl alcohol, phenylethanol, phenoxyethanol, 1-phenoxy-2-propanol (phenoxyisopropyl alcohol) and cinnamon alcohol.
• anionic surfactants sulfonates of camphor, toluene, xylene, cumene and naphthol can be used.
• sulfates of fatty alcohols with 6 to 22 carbon atoms such as, for example, capro alcohol, caprylic alcohol, 2-ethylhexyl alcohol, capric alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, palm oleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, linolyl alcohol, petol , Linolenyl alcohol, Elaestearyl alcohol, Arachyl alcohol, Gadoleyl alcohol, Behenyl alcohol and erucyl alcohol and their technical mixtures, such as are obtained, for example, from the hydrogenation of technical methyl ester fractions or aldehydes from Roelen's oxosynthesis.
• the surfactants can be used in the form of their alkali metal salts, in particular their sodium or potassium salts.
• hydrotropes are di- and polycarboxylic acids, such as malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, fumaric acid, maleic acid, tartaric acid, malic acid, citric acid and aconitic acid as well as polyacrylic acids and alkylphosphonic acids.
• the acids can be used in free form, but also in the form of their alkali salts or partial esters.
• hydrotropes are nonionic surfactants, in particular addition products of an average of 5 to 10 mol of ethylene oxide and fatty alcohols having 6 to 18 carbon atoms, which can have a conventional or narrow homolog distribution. Typical examples are adducts of 4 moles of ethylene oxide with octanol or 5 moles of ethylene oxide with decanol.
• Further suitable nonionic surfactants are, in particular, alkyl oligoglucosides and fatty acid N-alkyl glucamides. Typical examples of the latter substance classes are C 12/14 coconut alkyl glucos id and lauric acid N-methyl glucamide.
• the proportion of hydrotropes in the agents according to the invention can usually be 1 to 25, preferably 5 to 20,% by weight.
• Non-polar substances which have a flash point above 65 ° C. are preferred as solvents.
• Typical examples are cyclohexanol, methylcyclohexanol, tetralin and 3,5,5-trimethylhexanol.
• esters such as tributyl citrate or tributyl phosphate can be used as non-polar organic solvents.
• the proportion of solvents in the agents according to the invention can usually be 0 to 10, preferably 2 to 8,% by weight.
• the wetting agents according to the invention can be prepared by adding the mixed ethers and optionally the other ingredients in water. It is a purely mechanical process that is supported by stirring and elevated temperature (30 to 40 ° C); a chemical reaction does not take place.
• a typical wetting agent formulation has the following composition, for example:
• the amount in which the wetting agents according to the invention are added to the treatment liquors can be between 1 and 10, preferably 0.5 and 5 g per liter of liquor.
• the fleet can also contain other additives, e.g. As dyes, optical brighteners, alkalis such as sodium hydroxide, sequestering agents such as phosphonates and water glass.
• the wetting agents according to the invention are foam-free, rapidly wetting, highly alkali-resistant, stable in storage and readily biodegradable. They dampen the process foam and are therefore suitable for the production of agents for textile pretreatment.
• This includes in particular the alkaline pretreatment as well as the chlorine and peroxide bleaching of raw cotton.
• the usual pretreatment - such as cleaning or dyeing from a bath - of fibers and fiber mixtures such as cellulose, wool, polyamide, polyacrylonitrile or polyester fiber materials as well as polyacrylic / cotton and polyester / cotton fabrics.
• the essence of the present invention is the inventive selection of short-chain mixed ethers with a low content of propylene and ethylene oxide units, which are strictly linear in the fatty alkyl radical, from the large number of mixed ethers already known for these or similar applications.
• Another object of the invention therefore relates to the use of mixed ethers of the formula (I) for the preparation of wetting agents for textile pretreatment, in which they contain in amounts of 5 to 90, preferably 50 to 85% by weight, based on the agent could be.
• the wetting capacity was determined according to the immersion method with 1 g of active substance / 1, 20 ° C, in water of 16 ° d. For details of the method, see Tens.Surf.Det. 27, 243 (1990).
