Definitions
- the present application relates to a method for washing wool, in particular raw wool, and the use of certain fatty alcohol ethoxylates for washing wool.
- the object of the present application was now to find an ecologically harmless alternative to the toxicologically questionable surfactants previously used in wool laundry, especially in industrial raw wool laundry, e.g. to be found on the basis of nonylphenol, which represent an acceptable alternative for industry both in terms of washing capacity and price.
- branched fatty alcohol ethoxylates with 8 to 22 carbon atoms, optionally in admixture with dicarboxylic acids or their derivatives and / or alkylphosphonic acids or their derivatives, is claimed as detergents for wool.
- wool is understood to mean both the approx. 5 to 30 cm long hair of the various domestic breeds and the hair of South American llamas, camels, rabbits and goats.
- Most of the industrially processed wool is obtained from sheep.
- the wool is a protein fiber that mainly consists of keratin, which is one of the ski protein.
- the raw wool obtained from the sheep by shearing is contaminated by sand, dust etc. and contains large amounts of wool sweat, a mixture of potassium salts of fatty acids, hydroxy, amino and other organic acids, which is formed by drying animal fumes.
- the raw wool also adheres to the wool fat that is formed in the sebum of the sheep and mainly consists of lanolin, a mixture of different fatty acid esters.
- the wool from Australian Merino sheep for example, contains approx. 49% by weight wool fibers, approx. 19% by weight dirt, approx. 16% by weight fat, approx. 10% by weight water and approx. 6 wt% sweat.
- fatty alcohol ethoxylates are used in wool washing. These are ethoxylated fatty alcohols, these fatty alcohols obeying the general formula (I)
- R 1 represents a branched alkyl radical having 8 to 22 carbon atoms and 0 to 3 double bonds.
- saturated alcohols of the formula (I) preference is given to using saturated alcohols of the formula (I).
- Such fatty alcohols can be synthesized by known methods, the branched products of oxo synthesis being particularly suitable.
- Another source of branched fatty alcohols in the sense of the present application is the so-called Guerbet reaction. Linear primary fatty alcohols at 200 ° C. and increased pressure in the presence of copper or sodium via the intermediate stage of the aldehydes and subsequent aldol reaction become branched fatty alcohols condensed. Due to the conduct of the reaction, 2-alkyl alkanols are obtained by Guerbet synthesis. The Guerbet alcohols therefore follow the general formula (II)
- R and R 'independently of one another represent an alkyl radical having 1 to 12 carbon atoms.
- Particularly suitable branched fatty alcohols in the sense of the present application are 2-ethylhexanol, isooctanol, isononanol, isodecanol, isoundecanol, isododecanol and branched alcohols with 13 and 15 carbon atoms.
- the multi-branched ones are also suitable, for example 2,6-dimethyl-4-heptanol, 3,5,5-trimethyl-1-hexanol or 3,5-trimethylheptanol.
- any mixtures of ethoxylates of the above-mentioned branched fatty alcohols can be used.
- the branched fatty alcohols are ethoxylated by known methods under pressure and elevated temperatures in the presence of acidic or basic catalysts, preference being given to using alkoxylated compounds which are reacted with 4 to 12 mol and preferably 5 to 10 mol of ethylene oxide per mol of fatty alcohols.
- the fatty alcohol ethoxylates, dissolved as a surfactant component in the wash liquor, are used for washing wool, preferably raw wool.
- the ethoxylates are used in amounts of 0.1 to 10 g / l, preferably 0.5 to 5 g / l and in particular 0.5 to 2.5 g / l (active substance).
- auxiliaries which are selected from the group of the dicarboxylic acids or their derivatives and / or the alkylphosphonic acids or their derivatives.
- the use of these auxiliaries is therefore particularly preferred in the sense of the present technical teaching.
- Dicarboxylic acids follow the general formula (III)
- n is zero or an integer between 1 and 8.
- dicarboxylic acids their derivatives, in particular their nitrogen-containing derivatives, are preferred auxiliaries in the sense of the present technical teaching.
- Aminodicarboxylic acids such as aspartic and glutamic acid, their salts and the oligomers and polymers of these compounds are preferably used.
- the use of polyaspartic acid or its sodium or potassium salts is very particularly preferred.
- the molecular weight of the polyaspartic acid is preferably in the range from 2000 to 4000 and in particular from 2000 to 3000.
- the products are particularly notable for good biodegradability.
- Alkylphosphonic acid derivatives are also suitable auxiliaries for wool washing.
- Hydroxyethane diphosphonic acid which is preferably used in combination with aminotrismethylenephosphonic acid, is particularly preferred. If such auxiliary substances are also used, their use concentration in the wash liquor is in the concentration range from 0.01 to 1.0 g / l (active substance).
- the auxiliaries will typically be present in the liquor in amounts of 0.1 to 0.8 g / l. Mixtures are also suitable, in which case the total concentration of the auxiliaries is a maximum of 1.5 g / l of wash liquor.
- Particular preferred mixtures have combinations of branched C 10-12 fatty alcohols having from 5 to 8 parts of EO and polyaspartic acid and salts thereof proved.
- auxiliaries leads to a significant improvement in the washing effect, ie the proportion of residual fat in the wool again significantly reduced.
- Typical residual fat values are in the range from 0.1 to 5% by weight.
- a better remission of the washed wool is also observed.
- the fatty alcohol ethoxylates according to the invention are also toxicologically harmless and readily biodegradable.
- a method for washing wool is claimed, the wool using an aqueous liquor containing branched fatty alcohol ethoxylates having 8 to 22 carbon atoms, optionally in admixture with dicarboxylic acids or their derivatives and / or alkylphosphonic acids or their derivatives brought into contact at least once and then the wool is dried in a manner known per se.
- the temperature of the wash liquor is in the range from 25 to 80 ° C. Washing temperatures of 40 to 70 ° C. and in particular of approximately 45 to 65 ° C. are preferably set.
- the pH of the wash liquor is preferably between 7 and 9.
- the following procedure is used to check detergents on a laboratory scale: To differentiate the effectiveness of different washing systems, the used washing liquor is replenished to the original volume with (as small a proportion as possible) fresh liquor after each washing cycle in order to then use this regenerated liquor.
- the size of the increase in residual fat content and the decrease in whiteness correlates with the effectiveness of the system.
- the wool is brought into contact with the liquor between 1 and 15 times.
- the industrial processes are usually carried out continuously, with the wool passing through the individual baths one after the other and being freed from the washing liquor by squeezing out each bath.
- the residual fat content of the wool after going through the washing process is preferably in the range from 0.1 to 2% by weight and preferably in the range from 0.2 to 1% by weight, based on the raw wool weight.
- the washed raw wool is dried in a manner known per se, e.g. by hot air, and can then be processed further.
- Raw wool with different fat contents up to approx. 20% by weight was placed in an aqueous solution of the detergent and agitated gently. The pH was neutral or was adjusted to approximately 8.5 with soda. The raw wool sample weighed 50 g. The concentration of the fatty alcohol ethoxylate (Table I) in the wash liquor was 1.0 g / l. If necessary, additives (Table * II) were used in amounts of 0.10, 0.25 and 0.5 g / l. The temperature of the wash liquor was 64 ° C and 54 ° C. The washing time was 6 minutes each.
- Sedimentation of the wash liquor 2 liters of the wash liquor were filled up to the calibration mark in a measuring cylinder and the sedimentation was determined after 24 and 48 hours and stated in ml.
- Fat separation of the wash liquor 2 liters of the wash liquor were filled up to the calibration mark in a measuring cylinder and the fat cream of the wash liquor was determined after 24 and 48 hours and stated in ml.
- Tables III to VII The results are shown in Tables III to VII.
- Table IX shows the results of a commercially available product based on a C 9 11 iso polyglycol ether and Table X shows the results of a nonylphenol polyglycol ether for comparison. It can be seen that the detergents according to the invention are sometimes more efficient than the known products. Compared to the comparative products, in particular the nonylphenol derivative, the products according to the invention are toxicologically harmless and biodegradable.
