Description

Water repellent effects on textile surfaces

The invention describes a preparation which is applied to textile surfaces, woven fabrics, loops, knits, fibers, nonwovens and knitted fabrics and exhibits a water-repellent effect thereon. Furthermore, the invention comprises a process for the preparation of the preparation and the use of the preparation, including the textiles thus obtained.

Textile materials are used for a variety of applications. However, their absorbency and permeability to water are undesirable in many applications. For outdoor textiles such as rainwear and tarpaulins or permanent outdoor textiles such as awnings and geotextiles, these properties are disadvantageous. Since the sole choice of textile material can not find a technically adequate and economically acceptable solution to the problem, these textiles are treated with water-repellent agents. For a long time, the perfluorinated acrylate systems and the equipment based on them dominated the market. These fluorine-containing surface treatments not only allow excellent water repellency, but also bring along oil and dirt repellent effects. Despite these technical properties, the perfluorinated coatings are now in decline because they are considered to be persistent and bioaccumulative (M Santen, U.Kailee, Chemistry for AnyWeather, Greenpeace e.V., 2012, p. 5).

The use of waxes in the hydrophobization of textile surfaces has also been known to the skilled person for a long time. However, the equipment is not sufficiently stable to household laundry and must therefore be renewed regularly. A moderate improvement can be achieved by the use of zirconium or Aluminum salts of fatty acids are obtained (H.-K. Rouette, Encyclopaedia of Textile Finishing, Springer, 2000, pp. W91-W95, keyword "Water repellent finishing")., However, such refined fabrics suffer from a very waxy handle, very low air permeability and the concomitant loss of comfort and increased flammability due to the high wax surcharge on the textile surface.

Therefore, attempts have been made to enhance or supplement waxes in their properties. Thus, waxes are often applied with polymer dispersions. Thus, the use of fatty acrylate-based copolymers together with wax emulsions has been known for some time (C. Tomasino, Chemistry & Technology of Fabric Preparation & Finishing, pp. 158-171, web retrieval of 30.04.2013, http://infohouse.p2ric. org / ref / 06 / 05815.pdf). Solvent-based polyacrylates were first described in DE 1238215 A1, but due to their adverse process and environmental influences, such systems can not be used in the textile industry. Patent EP 2411575 Bl mentions the use of terpolymers based on alkyl acrylates, chlorine-containing vinyl compounds and styrene derivatives in combination with waxes as aqueous dispersions. However, the use of styrene-containing polymers is unsuitable due to the yellowing tendency of these compounds and also halogen-containing substances are undesirable for environmental reasons in the textile industry. Vinyl esters of the Kochsäuren as a component of copolymer wax dispersions were mentioned in EP 1424433 Bl, but are unfavorable due to the high price.

DE 10211549 B9 describes the preparation of a compound which is obtained from the reaction of a diol, alkanolamine or diamine with a diisocyanate or a dicarboxylic acid and finally admixed with a further isocyanate. In conjunction with waxing, this reaction product is used as a hydrophobic surface finish.

Recently, the use of a polyurethane coatings in DE 102009014699 AI has been described. However, the hydrophobicity described by the authors does not meet current requirements, especially since only contact angles have been tested and no washing tests have been carried out. This is understandable in that comparatively large amounts of emulsifiers are required and they must first be removed. As an alternative to the wax and polymer-based approaches, those based on silicones are used. Functionalized silicones and siloxanes have long been used for handle optimization (compare DE 4222483 A1 and documents cited therein).

The use of H-siloxanes for the hydrophobization of textiles is known for example from DE 1231663 AI. In combination with urea or melamine resins, wrinkle-free equipment can be achieved at the same time (cf also US 3,032,442 A). However, these known systems are known to have the serious disadvantage that elemental hydrogen can be released during textile finishing, which represents a considerable process risk. In addition, they require anhydrous, flammable solvents and toxicologically questionable catalysts and are therefore not applicable in the textile industry.

Water-repellent effects on textile surfaces are also described in US Pat. No. 2,758,946 A by equipping the common hydrolysis product of dimethylchlorosilane and alkylmethylchlorosilanes in the finishing liquor with the addition of water-soluble aminoplasts and tin or zinc catalysts. This approach is in no way sufficient today required security requirements.

Likewise, the use of alkyl-modified silicic acids or their esters from US 2785145 is state of the art. However, these finishes suffer from insufficient washing permanence.

EP 2152957 B1 also uses the described component from DE 10211549 B9 in conjunction with alkyl-modified organosiloxanes, which, however, can not achieve sufficient hydrophobicity before and after household washes.

The combination of wax and silicone oil emulsion for improving the friction and sliding properties of yarns is known to the person skilled in the art from WO 03/078726 A1 and the documents cited therein. The influence of this combination on the water repellency is not mentioned, rather such sizings are generally removed after the weaving processes.

A combination of zirconium paraffin wax and H-siloxane is described in GB 1287745 A1, but the application of organic, combustible solvent and with highly reactive catalysts is no longer acceptable today for safety reasons. JP 2006-124866 A1 reports on the use of a non-functionalized polydimethylsiloxane in compounds with a cross-linking agent, preferably based on a carbodiimide, for hydrophobicizing textile materials.

EP 1108765 Bl describes carboxy-functional silicones as water repellents for furs and leather, optionally together with paraffins. The disadvantage is that these substrates at the latest after the first household wash with a commercial alkaline detergent lose their water-repellent effect, since the present invention according to the necessary acid groups are then deprotonated. The authors also describe a dispersion process in which the silicone is first reacted with a base, then dispersed in a mixture of water and an organic solvent, from which finally this solvent has to be removed by distillation.

Aminoplasts are mostly used in the form of melamine or urea-formaldehyde resins as crease-resistant finishing of cellulosic fibers. Alkylmelamines and their resins as textile water repellents are known from BE 569962 AI. Similar approaches can also be found in DE 1594977 AI and DE 1570776 AI. In DE 60124597 12 such melamine derivatives are applied together with waxes on textiles to achieve water-repellent effects. With this incomplete fluorine-free system, however, neither adequate permanence nor the desired handle design can be achieved.

EP 1035200 A2 describes a wiper cloth finished with one or more hydrophobic components with the aim of producing a water-repellent film on an automobile surface treated therewith, wherein the hydrophobic finish is transferred from the textile to the wiped surface. The authors also state that the amount of emulsifier must not be too high for such a system, since otherwise the hydrophobing effect is lost. Accordingly, the smallest possible amounts of surface-active substances are advantageous.

The object of the present invention is to provide a preparation for producing water-repellent effects on textile surfaces by the combination of suitable active ingredients and the combination of these in the preparation with the lowest possible amounts of emulsifiers available. It has surprisingly been found that the combination of, on the one hand, silicone polymer and, on the other hand, wax and / or fatty acid ester, and preferably additionally provided with aminoplasts, results in permanent, wash-resistant hydrophobing of textile materials with a pleasant and soft feel and good air permeability. It is particularly advantageous that the plasticizer usually required can be saved.

It has been found, particularly surprisingly, that silicone polymers having a high alkyl density can be formulated particularly advantageously with wax and optionally aminoplast in one step. The process according to the invention describes a production process with the lowest possible amounts of surface-active substances and dispersants.

It is particularly surprising that excellent Waschpermanenzen the water-repellent effect can be achieved because the silicone polymer has a melting point of in particular -20 to 60 ° C, preferably from 0 to 50 ° C, particularly preferably from 20 to 40 ° C, the expert but it is known that melting points of hydrophobicizing components such as waxes must have a melting range greater than 60 ° C in order to achieve even moderate wash resistance.

The preparation according to the invention contains the following constituents: a) 1.0 to 50.0% by weight, preferably 2 to 20.0% by weight, silicone polymer b) 1.0 to 50.0% by weight, preferably 2 to 20.0% by weight, wax and / or

Fatty acid esters c) from 0.0 to 50.0% by weight, preferably from 1.0 to 50.0% by weight, particularly preferably from 2.0 to 10.0% by weight, of aminoplast, urea derivative and / or melamine derivative d % From 0.0 to 98.0% by weight of solvent e) from 0.0 to 50.0% by weight of crosslinking agent f) from 0.0 to 5.0% by weight of dispersing aids.

All data are by weight and refer to the entire preparation. The silicone polymer according to the invention comprises the necessary units M, N, O and the optional units P _a , P _b and also P _c and optionally the end groups X and Y:

and optional

p _a =

m, n and o are integers and can be chosen independently and assume values from 1 to 100,000. p _a , p _b , p _c can be independently determined as integers between 0 and 100,000. Preferred are such

Silicone polymers for which the relationship <<Π, in particular <Π applies and which have a nitrogen content of between 0.01 to 4.0% by weight, preferably 0.1 to 1.0% by weight, based on the total polymer. The nitrogen content is defined as follows: Mass (nitrogen in the polymer) * 100

Nitrogen content [%]

Mass (total polymer)

The unit M is the base unit of the silicone polymer. R ¹ is selected from the group of saturated or unsaturated, linear, branched and / or cyclic hydrocarbons and the aryls, hydroxy or alkoxy. For R ² , saturated or unsaturated, linear, branched and / or cyclic hydrocarbons and aryls can be used.

Preference is given to those polymers which carry saturated or unsaturated linear, branched and / or cyclic hydrocarbons having 8 to 50 carbon atoms, more preferably those having 16 to 30 carbon atoms.

Particularly preferred is the combination for the unit N, which consists of a methyl radical and a saturated or unsaturated, linear, branched and / or cyclic, aliphatic hydrocarbon having 8 to 50 carbon atoms, very particularly preferably having 16 to 30 carbon atoms.

The unit O carries amino-functional side groups and the radical R ³ . For example, amine-containing silanes from the Dynasylan® product gamme can be incorporated into the polymer by equilibration reactions. The radical R ³ may be a hydroxy, alkoxy, alkyl or aryl group in the context of the invention. The amine-containing side groups consisting of contain at least one nitrogen atom which is present as a primary, secondary, tertiary amine or as quaternary ammonium. R ⁴ can be selected from the group of saturated or unsaturated, linear, branched and / or cyclic hydrocarbons which may additionally carry amine groups in the chain, such as, for example, alkyleneaminoalkyl, alkyleneaminoalkyleneaminalkyl, or arylenes; particularly preferred are alkylenes having 1 to 6 Carbon atoms or Alkylenaminoalkylenamine having in each case 1 to 6 carbon atoms in the chains used. R ⁵ and R ⁶ can independently be selected from the following classes of substance: hydrogen, alkyl, amide, alkyleneamine, alkyleneaminoalkyl, Alkyleneaminoalkylenamine or longer homologues of this series. The optional units P _a , P _b and P _c contain further functionalizations for R ⁷ and R ⁸ in the form of organic radicals which may be bonded directly or indirectly via an alkylene or arylene spacer to the silicon atom, such as glycidyl, epoxy, alkyl ethers , Polyalkylene ethers, allyl, hydroxy, triorganylsilyl (organyls are alkyls and / or aryls), alkyl, alkoxy, aryloxy, vinyl, mercapto, phosphato. It is also possible to use further silicone polymer chains for R ⁷ and R ⁸ , so that a cross-branched network is formed which is built up with the units M, N, O and / or P _a , P _b , P _c . According to the invention, linkages of P and / or P _c via oxygen bridges to further silicon atoms are possible, which in turn must be part of the abovementioned units.

For linear silicone polymers, the peripheral units in the a- and ω-positions are saturated by the end groups X and Y. X and Y are independently selectable from hydroxy, triorganylsilyl, alkyl, aryl or hydrogen. Organyls in this context are functionalized or non-functionalized hydrocarbons, aryls or mixtures of these classes. With cyclic silicone polymers, these end groups are omitted; with branched or crosslinked silicone polymers, further end groups may be necessary to saturate the valencies.

It is particularly advantageous that due to the low melting point of the silicone polymer and the high density of alkyl functionalities, this polymer dissolves in waxes and / or fatty acid esters, and therefore can be emulsified in one step with these. As a result, the amount of hydrophobicity-disturbing emulsifiers is largely minimized and the water-repellent effects of the finished textiles improved.

For the purposes of the invention, one or more of the group of natural, semisynthetic, synthetic waxes and / or fatty acid esters may be considered as wax / fatty acid esters. Natural waxes can be distinguished into mineral, vegetable and animal waxes, all of which can be used according to the invention. Vegetable waxes are, for example, carnauba or Japan wax, mineral, for example, ceresin or montan waxes (raw montan waxes, acid waxes, ester waxes, partially hydrolyzed ester waxes, emulsifier-containing ester waxes, fully hydrolyzed montan waxes). Beeswax, lanolin are exemplary listed as animal waxes. Synthetic waxes are those based on polyalkylene (polyethylene, polypropylene, polyolefin waxes), polyol ether esters, Fischer-Tropsch waxes, oxidized PE and HDPE waxes, paraffins, amide waxes such as Ethylenbisstearoyldiamid. Semisynthetic waxes are chemically modified native source waxes such as hydrogenated jojoba waxes and Sasol waxes.

Also higher molecular weight esters of fatty acids, optionally containing still free acid and / or alcohol, can be used as waxes. Suitable acids are the saturated and unsaturated, linear, branched and / or ring fatty acids having 16 to 50 carbon atoms. Preferably, the linear, saturated or unsaturated acids having 16 to 36 carbon atoms in the chain are used. As a second component of the esters of the invention are Fettal koholreste or polyhydric alcohol radicals used. Monofunctional alcohols according to the invention consist of 16 to 50 carbon atoms and one hydroxy group and are composed of saturated or unsaturated and linear, branched and / or rings consisting of rings. Examples are cetyl alcohol, stearyl alcohol, behenyl alcohol, ambrein and betulin.

Suitable polyhydric alcohols are reactive aliphatic alcohols which carry two or more hydroxyl groups and can form compounds having more than one ester group under the conditions known to the person skilled in the art with the abovementioned fatty acids. By way of example, but not exclusively, ethylene glycol, propylene glycol, butylene glycol, pentylene glycol, pentaerythritol, trimethylolpropane, glycerol are to be listed.

Likewise, mixtures of polyethylene-acrylic acid copolymers, as present in Michem® Emulsion 34935, or polyethylene-maleic acid (anhydride) copolymers can be used.

Preferably, such waxes are used with a melting point of greater than 60 ° C, since it is known in the art that the hydrophobicity is often insufficient in low-melting waxes.

The aminoplast preferably to be used according to the invention comprises one or more amine-containing components based on urea, melamine or an aldehyde resin derived therefrom. The melamine component is composed as shown:

The radicals R ¹ to R ⁶ are independently selectable from the group hydrogen, saturated or unsaturated, linear, branched and / or cyclic hydrocarbons, aryls, preferably saturated or unsaturated aliphatic hydrocarbons having 8 to 50 carbon atoms in the chain, preferably 16 to 30, or the units R - S - T and / or U - V.

For the unit R, an alkylene or arylene can be used, for S an oxygen atom, α, ω-dioxyalkylene, α, ω-dioxyarylene, a carboxyl, carbonate or carbamate group, for T is a hydrogen, a saturated or unsaturated, linear, branched and / or cyclic hydrocarbon or an aryl group, wherein preferably saturated or unsaturated aliphatic hydrocarbons having 8 to 50 carbon atoms, particularly preferably 16 to 30, are used.

For the unit U, a carbonyl or carbamoyl can be used, for V is a saturated or unsaturated, linear, branched or cyclic hydrocarbons or an aryl group, preferably saturated or unsaturated aliphatic hydrocarbons having 8 to 50 carbon atoms, particularly preferably 16 to 30, are used.

The reaction products with aldehydes, the so-called melamine aldehyde resins, here preferably the melamine-formaldehyde resins obtained with formaldehyde, can also be used according to the invention, provided that at least one of the radicals R 1 to R _{6 has} one of the abovementioned functionalities. It is also possible according to the invention that one or more of the radicals R ¹ to R ⁶ carry a function of the type polyglycol or polyether. It is further possible for the purposes of the invention that diols or polyhydric alcohols are used in order to achieve crosslinking of various melamine units. For this purpose, at least one of the radicals R ¹ to R ^{6 is} replaced by a polyhydric alcohol, its ether or alkylol ethers and thus binds to a further melamine unit.

As an alternative to the melamine-based compounds described above, it is also possible to use ureas or thioureas and / or their aldehyde resins, which correspond in the following scheme:

The radicals R ⁷ and R ⁸ are independently selectable from the group of saturated or unsaturated, linear, branched or cyclic hydrocarbons, aryls, hydrogen, preferably the saturated or unsaturated aliphatic hydrocarbons having 8 to 50 carbon atoms, particularly preferably 16 to 30, are used, and / or the units R - S - T or U - V.

Z can be either an oxygen or a sulfur atom. W represents a hydroxyl-functionalized or a non-functionalized alkylene bridge, preferably ethylene, 1,2-dihydroxyethylene or 1,2-dialkoxyethylene. Mixtures of several aminoplasts are also inventive. The reaction products with aldehydes, the so-called urea-aldehyde resins, here preferably the urea-formaldehyde resins obtained with formaldehyde, can also be used according to the invention if at least one of the radicals R ₇ / R _{8 has} one of the abovementioned functionalities. Likewise, according to the invention, it is possible that one of the radicals R ⁷ or R ⁸ carries a function of the type polyglycol or polyether.

Furthermore, it is possible for the purposes of the invention that diols or polyhydric alcohols are used in order to achieve crosslinking of different urea units. For this purpose, at least one of the radicals R ⁷ to R ^{8 is} replaced by a polyhydric alcohol, its ether or alkylol ethers and thus binds to a further urea moiety.

It is particularly advantageous if a high density of alkyl functionalities is present in the aminoplast, so that this compound is soluble in waxes, and can therefore be emulsified in one step with these. As a result, the amount of hydrophobicity-disturbing emulsifiers is largely minimized and the water-repellent effects of the finished textiles improved.

For further improvement of the washing permanence of the effect described, fixers and / or crosslinkers from the group of blocked and unblocked isocyanates, diisocyanates, oligoisocyanates and also polyisocyanates, melamine-formaldehyde resins, zirconium salts, urea-formaldehyde resins, glycidyl- or epoxy groups-bearing crosslinking agents, for example according to the invention functionalized polyethyleneimines or polyvinylamines, aziridine-based crosslinkers such as Tubassist FIX 104 W, available from CHT R. Beitlich GmbH, and / or di-, oligo- or polycarboxylic acids, optionally in combination with suitable catalysts, which increase the reactivity and / or selectivity of the crosslinking used.

In the group of di-, oligo- or polyfunctional carboxylic acids are compounds of the type

L, (CO ₂ H) _k , wherein L is an organic radical selected from the group of optionally functionalized alkyl, aryl, alkenyl, alkylaryl, arylalkyl, arylalkenyl, alkenylaryl, I as a number either 0 or 1 and k is a number between 2 and 100000 covers. Alkanedicarboxylic acids are particularly preferred, in particular malonic acid, maleic acid, derivatives of succinic acid and oxalic acid. As oligo- and polycarboxylic acids in particular alkyl oligoglucoside, alkylpolyglycosides or Aryloligocarbonsäuren should be mentioned, particularly preferably butane tetracarboxylic acid, all-c / ^'sl, 2,3,4 cyclopentanetetracarboxylic, tricarballylic, citric acid, 1,2,3-trans- Propentricarbonsäure , Succinic acid and derivatives of polyacrylic acid and polymethacrylic acid as homopolymers or copolymers.

Suitable catalysts for the fixers are generally Lewis acids or bases. Magnesium chloride is particularly preferably used alone or in combination with Bronsted acids, preferably ortho-phosphoric acid, citric acid, sulfuric acid. Alternatively, Brönsted acids, preferably ortho-phosphoric acid, citric acid, sulfuric acid without Lewis acid can be used. Also known is the use of basic catalysts such as amines, hypophosphites, phosphonates, pyro and polyphosphates or alkali.

The preparation is in the form of a solution, dispersion or emulsion in a solvent. Preference is given to using water, possibly in mixtures with alcohols, esters, glycols, polyols, glycol ethers, polyvinyl alcohols or polyol ethers.

To prepare the preparation in the form of dispersions, emulsions or solutions, it is possible, for example, to use dispersants from the group of anionic, cationic or nonionic surfactants, optionally in combination with acids or bases. To adjust the viscosity of the preparation, it is possible to add rheological additives, such as carboxyalkyl polysaccharides or suitable polyacrylates.

The process for dispersing the ingredients comprises the steps

Common melting of the essential constituents silicone polymer, wax and / or fatty acid esters and preferably aminoplast including any necessary dispersing aids

Time-shifted solvent entry containing optional

Dispersing aids, acid and / or base above the melting point of the aforementioned mixture Reduction of the particle size of the preparation by introduction of mechanical energy

Silicone polymer, wax and / or fatty acid esters and optionally aminoplast are brought to the melt with dispersing aids at elevated temperature and successively mixed with the solvent optionally containing further dispersing aids, acids or bases at elevated temperature, the temperature between the melting point of the mixture and the Boiling temperature of the solvent should be. For the subsequent or simultaneous comminution of the particle size, methods and systems known to the person skilled in the art can be used. This includes the use of rotor-stator systems, rotor-rotor systems, pressure homogenizers, ultrasound probes, homogenizers and porous membrane emulsifier units.

Particularly preferred for the purposes of the invention are those building blocks which are soluble in each other, optionally with the aid of elevated temperature. As a result, the preparations can be produced with a minimum amount of emulsifiers. This is particularly advantageous because larger amounts of these auxiliaries disturb the water-repellent effects of the finishes, as is known to the person skilled in the art from DE 1135418 A1.

The preparation on which the invention is based and the preparation forms contained therein can also be combined with customary textile auxiliaries known to the person skilled in the art and applied together in standard textile processes. These include, for example, plasticizers, high-performance resins, brighteners, dyes, hydrophilizing or other water repellents, fluorocarbons, anti-pilling additives, fixers, crosslinkers, zirconium salts, surfactants, polymeric binders, adhesives, slip resistance and / or pigments. The textile auxiliaries thus obtained can be used as liquors, foams or pastes for the textile finishing of fibers, fabrics, knitted fabrics, knitted fabrics or nonwovens. Also, the combination of these additives and the aforementioned components to a preparation for the finishing of textiles is according to the invention. Suitable textile-technological processes include, for example, exhaust processes or forced applications such as coating, equipment by padding, printing, spray processes, monofilament application and / or dyeing. If necessary, can Stabilization of finishing solutions also common emulsifiers, wetting agents and / or deaerators are added.

The textile material used in the present invention may be made of natural fibers such as cotton, bast fibers, hard fibers, wool, silk, mineral fibers and / or synthetic fibers such as regenerated cellulose fibers, polylactic acid, polyester, polyamide, polyimide, polyamideimide, polyphenylene sulfide, aramid, polyvinyl chloride, polyacrylonitrile , Polyvinyl acetal, polytetrafluoroethylene, polyethylene, polypropylene, polyurethane, elastane, carbon fibers, silicate fibers, glass fibers, basalt fibers, metal fibers, these contain or consist of mixtures of the materials mentioned. Also, laminated fibers or fibers cast in a composite material are according to the invention.

Examples:

All percentages in the examples are percentages by weight. The water repellency was determined according to DIN EN 24920 by the so-called spray test. In addition to the values 50, 70, 80, 90 and 100 specified in the standard, a complete, double-sided wetting of the textile sample, whereby the adhering water also penetrates the non-irrigated areas by capillary forces, is given the value 0. The finished textiles were subjected to a number of household washes according to DIN EN ISO 6330 at 40 ° C to check the washing permanence. The air permeability was determined according to ISO 9237, the breathability according to ISO 15496. The haptic evaluation was classified into five softness levels (very soft, soft, moderate, stiff, very stiff).

The dispersions were stabilized by introduction of mechanical energy on a homogenizer of the type LAB 100 from A. P. V. -Schröder GmbH, Lübeck. The air permeability was carried out on a test rig of the type "material testing machine" Karl Schröder KG.

The equipment was a laboratory tampon Walter Mathis AG used, the samples were dried in a laboratory clamping frame "Mathis Labdryer" the same company provided with a control unit "Programmer LTE". All finishing liquors were 2 g / L Kollasol SD added to improve the wetting of the textile pattern. The liquor pick-up of the samples is defined as the percentage increase in mass by the liquor and was determined by weighing the samples before and after the finish. It was about 75% for both materials.

Subsequently A mixture of 2.7 g of water, 0.91 g of sodium hydroxide solution (50% in water) and 0.88 g of tetrabutylphosphonium hydroxide (40% in water) was added. At 90 ° C was stirred for 30 min and then the resulting alcohol was distilled off. Then 423.29 g of HANSA SW 3020 were added and the mixture was stirred at 90 ° C. for 3 h. Subsequently, 1.42 g of lactic acid (80% in water) were added and stirred for a further 30 min. Thereafter, the temperature was raised to 140 ° C. Under vacuum 64g volatile components were separated within 2h. 1000 g of a slightly yellow liquid having about 0.4% of nitrogen and a viscosity of about 1000 mPas were obtained.

Production of silicone polymer 2

A four-necked flask equipped with stirrer, dropping funnel, thermometer and reflux condenser was charged with 56.4 g of 3-aminopropylmethyldiethoxysilane and heated to 75.degree. Subsequently, 11.7 g of water were added. At 85 ° C was stirred for 3h and then the cleavage alcohol distilled off. Thereafter, 1013 g HANSA SW 3068 were added and stirred homogeneously. Subsequently, 2 g of tetrabutylphosphonium hydroxide (40% in water) were added and stirred at 90 ° C for 5 h. Subsequently, 0.33 g of lactic acid (80% in water) was added and stirred for a further 30 min. Thereafter, the temperature was raised to 140 ° C. Under vacuum 50g volatile components were separated within 2h. There were obtained 1000 g of a slightly yellowish solid (melting point about 30 ° C) with about 0.3% nitrogen.

Reference Example 1:

Exemplary embodiment 14 - determination of the respiratory active:

To check the influence of breathability, a reference pattern was first created. On a polyester sample, a thin membrane film was laminated to achieve the desired windproofness with simultaneous breathability. For this purpose, the material was preimpregnated with 5 g / l TUBIGUARD 21 by padding. Subsequently, the now preimpregnated goods on the tenter frame for 2.5 min at 105 ° C was dried. The adhesive used was LAMETHAN ADH1, which was mechanically foamed to a foam weight of 200 g / l. The foamed adhesive composition was applied to the preimpregnated textile by means of a doctor blade with a layer thickness of 0.5 mm. It was then dried at 105 ° C. for 2.5 minutes on the tenter. The breathable membrane film LAMETHAN LB 25 was laminated to the adhesive side of the textile with the aid of a press shop. Subsequently, the resulting textile / membrane composite was fixed to the tenter frame at 145 ° C for 2.5 min.

These operations described above for the reference pattern have also been used to create a textile impregnated with a water-repellent finish. For this purpose, a preimpregnation was carried out with 160 g / L of a liquor from application example 1 and 40 g / l Tubicoat FIX FC. The spray value obtained was 100. The breathability of the samples was based on ISO 15496 tested. The found Re values of the reference sample and that impregnated with Application Example 1 were identical.

By means of this example, it can be shown that no negative change in the breathability results from the finish according to the invention.
