Abstract

The invention relates to textile treatment agents containing (a) quaternary esters and (b) paraffin waxes.

Description

Field of the Invention

The invention is in the field of textile treatment agents and relates to new ones Preparations for finishing textiles, containing combinations of cationic Surfactants and waxes and their use.

State of the art

Esterquats find a pleasant softness due to their properties, textiles and fibers Grip to give, especially as a softener ("softener") use. in this connection exploiting the ability of the cationic surfactants to attach to the fibers and thereby u. a. to reduce the static charge, so to provide an anti-static equipment. By combining ester quats with polyolefin waxes, as in the European patent EP 0784666 B1 (Cognis) is described, the soft grip can even be improved become; in particular, the friction is reduced and the ironing is treated in this way textiles significantly relieved. Corresponding products can be found under, for example the name "Vernell Easy" already on the market. After the application technology Properties of the products are not satisfactory in every case, has the task of present invention consisted of making new textile treatment agents available places that are more effective than in terms of antistatic equipment and low friction the products of the prior art or with the same performance with reduced Amount used is reached.

Description of the invention

The invention relates to textile treatment compositions containing:

• a) Esterquats and
• b) paraffin waxes.

Surprisingly, it was found that the new textile treatment agents are becoming obsolete visibly antistatic equipment, reducing the friction and thus improving the Ironability compared to known mixtures of esterquats and polyolefin waxes signi prove fictionally superior.

esterquats

Quaternized fatty acid trietha are generally referred to as "esterquats" understood nolamine ester salts. These are known substances that can be found in the relevant methods of preparative, organic chemistry can be obtained. In this To in relation to the international patent application WO 91/01295 (Henkel) after which one triethanolamine in the presence of hypophosphorous acid with fatty acid Ren partially esterified, air passed and then with dimethyl sulfate or ethylene oxide quaternized. From German patent DE 43 08 794 C1 (Henkel) is also a Process for the preparation of solid ester quats known in which the quaternization of Triethanolamine esters in the presence of suitable dispersants, preferably fatty alcohols alcohol, performs. Overviews on this topic are, for example, by R. Puchta et al. in "Tens.Surf.Det.", 30, 186 (1993), M. Brock in "Tens.Surf.Det.", 30, 394 (1993), R. Lagerman et al. in "J.Am.Oil.Chem.Soc.", 71, 97 (1994) and I.Shapiro in "Cosm.Toil.", 109, 77 (1994) appeared.

The quaternized fatty acid triethanolamine ester salts preferably follow the formula (I):

in which R ¹ CO for an acyl radical with 6 to 22 carbon atoms, R ² and R ³ independently of one another for hydrogen or R ¹ CO, R ⁴ for an alkyl radical with 1 to 4 carbon atoms or a (CH ₂ CH ₂ O) _q H -Group, m, n and p in total for 0 or numbers from 1 to 12, q for numbers from 1 to 12 and X for halide, alkyl sulfate or alkyl phosphate. Typical examples of esterquats which can be used in the context of the invention are products based on caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, isostearic acid, stearic acid, oleic acid, elaidic acid, arachic acid, behenic acid and erucic acid and their technical mixtures, as they occur, for example, in the pressure splitting of natural fats and oils. Technical C _12/18 coconut fatty acids and in particular partially hardened C _16/18 tallow or palm fatty acids and high-elite C _16/18 fatty acid cuts are preferably used. The fatty acids and the triethanolamine can be used in a molar ratio of 1.1: 1 to 3: 1 to produce the quaternized esters. With regard to the application properties of the ester quats, an application ratio of 1.2: 1 to 2.2: 1, preferably 1.5: 1 to 1.9: 1, has proven to be particularly advantageous. The preferred ester quats represent technical mixtures of mono-, di- and triesters with an average degree of esterification of 1.5 to 1.9 and are derived from technical C _16/18 tallow or palm fatty acid (iodine number 0 to 40) , From an application point of view, quaternized fatty acid triethanolamine ester salts of the formula (I) have proven to be particularly advantageous in which R ¹ CO for an acyl radical having 16 to 18 carbon atoms, R ² for R ¹ CO, R ³ for hydrogen, R ⁴ for a methyl group , m, n and p is 0 and X is methyl sulfate. Corresponding products are on the market under the Dehyquart® AU brand (Cognis Deutschland GmbH).

In addition to the quaternized fatty acid triethanolamine ester salts, quaternized ester salts of fatty acids with diethanolalkylamines of the formula (II) are also suitable as esterquats:

in which R ¹ CO for an acyl radical with 6 to 22 carbon atoms, R ² for hydrogen or R ¹ CO, R ⁴ and R ⁵ independently of one another for alkyl radicals with 1 to 4 carbon atoms, m and n in total for 0 or numbers from 1 to 12 and X represents halide, alkyl sulfate or alkyl phosphate.

Finally, the quaternized ester salts of fatty acids with 1,2-dihydroxypropyl dialkylamines of the formula (III) should be mentioned as a further group of suitable ester quats:

in which R ¹ CO for an acyl radical with 6 to 22 carbon atoms, R ² for hydrogen or R ¹ CO, R ⁴ , R ⁶ and R ⁷ independently of one another for alkyl radicals with 1 to 4 carbon atoms, m and n in total for 0 or numbers from 1 to 12 and X represents halide, alkyl sulfate or alkyl phosphate.

Furthermore, suitable ester quats are substances in which the ester bond is replaced by an amide bond and which preferably follow the formula (IV) based on diethylene triamine:

in which R ¹ CO represents an acyl radical having 6 to 22 carbon atoms, R ^{2 represents} hydrogen or R ¹ CO, R ⁶ and R ⁷ independently of one another represent alkyl radicals having 1 to 4 carbon atoms and X represents halide, alkyl sulfate or alkyl phosphate. Such amide ester quats are available, for example, under the Incroquat® (Croda) brand on the market.

Finally, substances which are obtainable on the basis of ethoxylated castor oil or its hardening products and preferably follow the formula (Y) are also suitable as esterquats:

in which R ⁸ CO is a saturated and / or unsaturated, ethoxylated hydroxyacyl radical having 16 to 22, preferably 18 carbon atoms and 1 to 50 oxyethylene units, A is a linear or branched alkylene radical having 1 to 6 carbon atoms, R ⁹ , R ¹⁰ and R ¹¹ independently of one another represent hydrogen or an alkyl group having 1 to 4 carbon atoms, R ^{12 represents} an alkyl radical having 1 to 4 carbon atoms or a benzyl radical and X represents halogen, alkyl sulfate or alkyl phosphate.

With regard to the selection of the preferred fatty acids and the optimal degree of esterification the examples given for (I) also apply to the esterquats of the formulas (II) to (V).  

To produce the esterquats of formulas (I) to (V), both fatty acids and the corresponding triglycerides are assumed. Such a procedure, the stell representative of the corresponding state of the art is to be mentioned in the eu European patent EP 0750606 B1 (Cognis) proposed. It is also possible the condensation of the alkanolamines with the fatty acids in the presence of defined amounts Dicarboxylic acids, such as. B. oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid, Glutaric acid, adipic acid, sorbic acid, pimelic acid, azelaic acid, sebacic acid and / or Perform dodecanedioic acid. This leads to a partially oligomeric Structure of the ester quats, which is particularly evident when using adipic acid Clear solubility of the products can be beneficial. Corresponding products under the Brand Dehyquart® D 6003 (Cognis Deutschland GmbH) are commercially available and who described for example in European Patent EP 0770594 B1 (Cognis). The ester quats usually come in the form of 50 to 90% by weight alcoholic solution on the market, which can be easily diluted with water if required.

paraffin waxes

Paraffin waxes produce commercially available substances, for example in the course of processing Processing of petroleum distillates and z. B. are available from BASF. typically, these waxes have molecular weights in the range of 100 to 1000 daltons. Usually they reach the market in the form of aqueous dispersions, the solids content in the range have from 25 to 50% by weight. The final preparations can be components a) and b) in a weight ratio of 90:10 to 10:90, preferably 75:25 to 25:75 and in particular 60: 40 to 40: 60 included. The total content of components a) and b) can be in Contain a total of 5 to 80, preferably 10 to 30 or 50 to 75% by weight, depending on whether concentrates or application dilutions are used.

Industrial applicability

Since the binary mixtures are suitable for finishing fibers, yarns and textiles in such a way that they are easier to iron, another object of the invention relates to the use of mixtures comprising:

• a) Esterquats and
• b) paraffin waxes

for the textile finishing of such textile fabrics. In the textile treatment In addition to components a) and b), other typical auxiliaries and additives can be used be included. In the simplest case, these are solvents, such as water, Ethanol, isopropyl alcohol, ethylene glycol, propylene glycol or glycerin. Also included can be emulsifiers and other waxes, for example Po lyolefin waxes can act.  

Examples

Different mixtures of esterquats and paraffin or polyolefin waxes were made placed and applied in amounts of 0.1 wt .-% solid on polyester yarn, which with Speeds of 2 to 200 m / min were spooled. The friction was opposed coefficient of static as well as the static charge determined. The results are in Table 1 summarized. Examples 1 to 4 are according to the invention, Example V1 is used for ver equal.

Table 1

Friction resistance and static charge (quantities based on solids as% by weight)

It can be seen that the agents according to the invention are those of the prior art based on Polyolefin waxes are far superior. So the friction resistance is halved and the sta table charge reduced to a third.
