Definitions

• the invention relates to mercerizing and / or lye wetting agents which contain alkali and / or ammonium salts of 2-ethylhexyl sulfate, end group-capped polyethers and optionally trialkyl phosphates.
• Mercerizing and leaching cotton i.e. H. the treatment of cellulose with alkalis of different concentrations serves the purpose of giving the fibers better gloss effects, an increased absorption capacity for dyes, greater tear strengths and a softer, fuller feel.
• the concentrated sodium hydroxide solution used in practice does not have a large wetting power.
• wetting is made very difficult by the hydrophobic substances adhering to the cellulose fibers.
• wetting agents are therefore added to the mercerizing and / or leaching liquors in many cases (Chwala / Anger: "Handbook of Textile Aids" pages 347-350, 1977).
• the wetting agents should not cause foaming in the bases, should be stable within a wide range of alkali concentrations and should be very well biodegraded.
• these known requirements are not satisfactorily met by most known mercerizing and / or lye wetting agents.
• the salts of 2-ethylhexyl sulfate that are frequently used as wetting agents tend to be in mercerising and / or lye liquors to excessive foaming.
• end-capped alkyl alcohol ethoxylates are known as foam-suppressing additives in low-foam cleaning agents.
• the object of the invention was to develop low-foaming, alkali-stable and readily biodegradable mercerizing and / or lye wetting agents with very good shrink wetting properties.
• wetting agents which contain alkali and / or ammonium salts of 2-ethylhexyl sulfate, special end group-capped polyethers and optionally trialkyl phosphates largely meet the high demands placed on them.
• the subject of the invention are mercerizing and / or lye wetting agents 15-30% by weight of alkali and / or ammonium salts of 2-ethylhexyl sulfate 1 - 10 wt .-% of a mixture of end-capped polyethers of the general formulas in which R1 is a straight-chain alkyl radical having 1 to 20 C atoms, R2 is a straight-chain alkyl radical having 1 to 20 C atoms and R3 is an alkyl, alkenyl, cycloalkyl, aryl, arylalkyl or alkylaryl radical with 1 to 22 C atoms means and n represents 2 and / or 3 and / or 4 and x is a number between 2 and 25, and B) R4 - O - (C n H 2n O) x - R3, wherein R4 is an alkyl or alkenyl radical with 8 to 22 C atoms and R3 is an alkyl,
• the mercerizing and / or lye wetting agents according to the invention preferably contain end-capped polyethers of the general formulas A and B in which the radicals R 1 are a straight-chain alkyl radical with 8 to 12 C atoms, R 2 is a straight-chain alkyl radical with 6 to 10 C atoms, R 3 Alkyl radical with 1 to 6 carbon atoms and R4 an alkyl or alkenyl radical with 12-18 C atoms and the indices n, the number 2 and x mean a number between 2 and 10.
• the weight ratio of the end group-capped polyethers A: B is preferably between 0.1 and 10, particularly preferably between 0.9 and 1.1.
• the end group-capped polyethers of the general formula A can be obtained by known processes: Guerbet alcohols, prepared by reacting saturated, primary alcohols with 1-20 C atoms in the presence of alkali (see, for example, in Angew. Chem.
• the end group-capped polyethers of the general formula B can also be prepared by processes known from the literature.
• the educts are aliphatic, saturated and / or unsaturated alcohols of natural and / or synthetic origin with 8-22 carbon atoms, for example octyl, decyl, dodecyl, myristyl, cetyl, stearyl, oleyl, linoleyl, behenyl -, Eruca alcohol or mixtures of these alcohols used.
• Alcohols with 12-18 C atoms for example lauryl, myristyl, cetyl, stearyl, oleyl alcohol and mixtures of these alcohols, are preferred.
• alkoxylation of these alcohols with ethylene oxide, propylene oxide and / or butylene oxide, preferably with ethylene oxide is carried out by known industrial processes (See, for example, in "Chemical Technology" Volume 7, pages 131-132, Carl-Hanser Verlag, Kunststoff-Vienna (1986)).
• the alkoxylated alcohols are then reacted in a manner known per se, preferably with alkyl halides having 1 to 6 carbon atoms, for example methyl chloride, ethyl chloride, propyl chloride, butyl chloride, butyl bromide, pentyl chloride and / or hexyl chloride, to give the end group-capped polyethers.
• alkali and / or ammonium salts of 2-ethylhexyl sulfate contained in the wetting agents according to the invention are commercially available products, for example Texapon R EHS, Henkel KGaA.
• the trialkyl phosphates optionally contained in the wetting agents according to the invention are prepared in a manner known per se, for example by reacting phosphorus oxychloride with alkyl alcohols (Chem. And Ind. 1962 , 1032-1035).
• the alkyl alcohols used are, for example, methanol, ethanol, propanol, n-butanol, n- Pentanol or n-hexanol used.
• the wetting agents according to the invention preferably contain 0.5 to 5% by weight of trialkyl phosphates.
• the wetting agents according to the invention are prepared at 18 to 50 ° C. by stirring the individual components, if appropriate after melting, to give a homogeneous solution.
• the wetting agents according to the invention which are in the form of aqueous solutions, are notable for high shrink wetting capacity and low foaming. Furthermore, they are very easily biodegradable.
• the wetting agents according to the invention contain no or only small amounts of solvents such as polyalcohols, for example hexylene glycol and / or butylene glycol.
• the wetting agents according to the invention can be used Use both for mercerizing and for leaching, for example, cellulose-containing woven goods, knitwear and / or yarns.
• the content of the wetting agents according to the invention in the mercerizing and / or leaching liquors is between 2 and 12 g / l liquor.
• the shrink wetting capacity was determined in accordance with DIN 53987 (Landolt method) at 18 ° C with a wetting agent amount of 5 g / l (indication of the shrinking capacity in%).
• the foaming power was determined according to the glass frit method described in Melliand textile reports 48 , 311-315 and 450-456 at 18 ° C. with a wetting agent amount of 5 g / l.
• the foam height is given in mm (200 mm is the maximum height under the test conditions).
