Definitions

• the present invention concerns a liquid textile-pretreating agent useful in all continuous and batch pretreatment operations which is based on phosphoric esters of alkoxylated Guerbet alcohols and is very stable to alkali not only in the formulation but also in the liquor.
• the pretreatment of the natural or synthetic fibre materials constitutes an important basis for the further processing.
• the various operations such as desizing, scouring, bleaching or mercerizing employ a wide range of textile chemicals, examples being surfactants, dispersants, emulsif ⁇ ers, bleaches, foam suppressants or defoamers.
• these auxiliaries as they are known have to meet is high stability to alkali, especially in the alkaline scouring of woven cotton fabric. There is accordingly a constant need for new active compounds having a suitable performance profile.
• n is from 1 to 3
• x is from 4 to 12
• R is a radical of the formula (II)
• the present compounds are highly stable surfactants which can be present as a highly concentrated, for example 60% solution in water without any need for additives. This combines with good wettability and low foam-forming tendency into a unique performance profile. Especially the extremely high stability to alkali not only in the formulation but also in the liquor predestines these compounds for the alkaline scour, but use as a dispersant, as an emulsif ⁇ er or as a defoamer component is also possible.
• n is 2 or 3
• s is from 0 to 4
• the sum total of (r + s) is from 5 to 7.
• the index m is an average value, and a particularly preferred value for m is from 1.2 to 1.3.
• the present compounds are prepared by alkoxylation of appropriate Guerbet alcohols as described in WO 03/091192 Al and subsequent phosphation, preferably with phosphorus pentoxide.
• the alkylene oxide units of the Guerbet alcohols used are mostly ethylene oxide or propylene oxide units, but mainly ethylene oxide units combined with low fractions of propylene oxide or else only ethylene oxide units.
• Phosphation is effected by portionwise addition of the phosphating agent at 90 to 120°C during 4 to 24 hours in the absence of air.
• the present compounds can be used as such or in the form of an aqueous composition for pretreating textiles.
• the present invention thus further provides a composition comprising an aqueous solution of one or more compounds of the formula (I) and also further auxiliaries.
• the aqueous composition comprises 40% to 70% by weight of compound (I), although about 2% to 4% by weight can also be present in the form of the sodium salts.
• the composition may further comprise 0.1% to 3.5% by weight of further auxiliary materials, examples being surfactants, biocides, defoamers or foam suppressants.
• composition according to the invention is obtainable by simply mixing its constituents.
• a preferred use of compounds of the formula (I) or of the abovementioned aqueous composition is the pretreatment of textiles in continuous or batch operations under alkaline conditions.
• Alkali stability What is tested is the alkali stability of 5 g/1 of surfactant, with 100 ml of liquor being made up in each case. The test takes place at room temperature 20 to 25°C. The required amount of aqueous sodium hydroxide solution is weighed into a glass beaker and made up to 95 ml with demineralized water. 5 ml of a 10% surfactant solution are added to the alkali batches with stirring. The glass beakers are left to stand at room temperature for 24 hours without stirring.
• a 1000 ml graduated cylinder 60 mm in internal diameter and 430 mm in internal height is used.
• the test liquid is allowed to pour out from a 2 1 separating funnel through a capillary 70 mm in length and 2 mm in internal diameter from a height of 600 mm, measured from the outlet of the capillary above the floor of the cylinder.
• 500 ml of the solution to be tested are filled into the separating funnel and allowed to flow out into the graduated cylinder through the capillary-controlled efflux rate of about 0.17 1/min.
• a stopwatch is started and the entire volume (foam volume plus solution volume) is read off the cylinder scale. The reading is repeated after one minute.
• the alkaline foam performance is tested using a surfactant concentration of 2 g/1 in 2° Be NaOH solution in demineralized water, with 2° Be NaOH being equivalent to 12 g/1 of NaOH solid or 30 ml/1 of NaOH 36° Be.
• the test temperature is 20 to 25°C.
• This test method determines the number of seconds a fabric sample takes to sink to the bottom of a glass beaker 1 1 in content, 14 cm in height and 10 cm in diameter in a surfactant solution.
• the fabric sample used is a cotton test cloth, from EMPA Testmaterialien AG of St. Gallen, Switzerland. Circularly round discs 3.5 cm in diameter are die cut out of this cloth and dipped with a special holder into the surfactant solution. The wetting action is tested in 2° Be NaOH at
