Description

Gegenstand der DE-A-2 644 073 sind Reinigungsverstärker zum Chemischreinigen von Textilien auf der Basis von anionaktiven und kationaktiven Tensiden, Lösungsmitteln und Wasser, gekennzeichnet durch folgende Zusammensetzung:

DE-A-2 644 073 relates to cleaning boosters for the chemical cleaning of textiles based on anionic and cationic surfactants, solvents and water, characterized by the following composition:
Figure imgb0001

Diese Reinigungsverstärker besitzen ein hohes Schmutztragevermögen und eignen sich besonders zur Reinigung von weißen oder pastellfarbigen Textilien aus den üblichen Fasermaterialien, wie Wolle, Baumwolle, Regeneratcellulose, Polyamid, Polyester, Polyacrylnitril, wobei auch sehr empfindliche Textilien aus solchen Fasermaterialien, deren hohe Vergrauungstendenz bekannt ist, problemlos gereinigt werden können.These cleaning enhancers have a high dirt-carrying capacity and are particularly suitable for cleaning white or pastel-colored textiles made from the usual fiber materials, such as wool, cotton, regenerated cellulose, polyamide, polyester, polyacrylonitrile, and also very sensitive textiles made from such fiber materials, whose high graying tendency is known. can be easily cleaned.

Es hat sich jedoch gezeigt, daß diese Reinigungsverstärker eine nachfolgende wasserabweisende Ausrüstung, wie sie besonders für Sport- und Wetterschutzbekleidung infrage kommt, in ihrer Wirksamkeit beeinträchtigen können. Dieses Problem ist an sich bekannt, es beruht auf der Anwesenheit von Reinigungsverstärker-Resten in den gereinigten Textilien (J. Kurz »Die Praxis der Chemischreinigung«, 111, S. 222).However, it has been shown that these cleaning boosters can impair the effectiveness of a subsequent water-repellent finish, as is particularly suitable for sports and weather protection clothing. This problem is known per se, it is due to the presence of cleaning booster residues in the cleaned textiles (J. Kurz "The Practice of Chemical Cleaning", 111, p. 222).

Der Erfindung liegt die Aufgabe zugrunde, einen Reinigungsverstärker für die Chemischreinigung zu entwickeln, welcher für die Reinigung von Textilien, insbesondere Sport- und Wetterschutzbekleidung, aus vergrauungsempfindlichen Textilmaterialien besonders geeignet ist, ohne eine nachfolgende Hydrophobierung in ihrer Wirksamkeit zu beeinträchtigen. Die Aufgabe wird dadurch gelöst, daß man in der Reinigungsverstärker-Mischung der DE-A-2 644 073 das Petrolsulfonat durch Chlorparaffinsulfonate der Kettenlängen C12―C30 ersetzt.The invention has for its object to develop a cleaning booster for dry cleaning, which is particularly suitable for cleaning textiles, especially sports and weather protection clothing made of graying-sensitive textile materials, without impairing the effectiveness of a subsequent hydrophobization. The object is achieved by replacing the petroleum sulfonate in the cleaning booster mixture of DE-A-2 644 073 with chloroparaffinsulfonates of chain lengths C 12 ―C 30 .

Gegenstand der Erfindung sind somit Reinigungsverstärker zum Chemischreinigen von Textilien auf der Basis von

Figure imgb0002
wobei das Verhältnis von a : (b + c) =1 :4 bis 1 : 12, und das Verhältnis von b : c=1 : 0,8 bis 1 : 1,5 beträgt, die dadurch gekennzeichnet sind, daß sie als weitere Sulfonate Chlorparaffinsulfonate der Kettenlängen C12- C30 enthalten.The invention thus relates to cleaning boosters for the chemical cleaning of textiles based on
Figure imgb0002
 wherein the ratio of a: (b + c) = 1: 4 to 1:12, and the ratio of b: c = 1: 0.8 to 1: 1.5, which are characterized in that they are further Sulfonates contain chloroparaffinsulfonates of chain lengths C 12 - C 30 .

Als oberflächenaktive quaternäre Ammoniumverbindungen werden die in der DE-A-2 644 073 beschriebenen Kationtenside eingesetzt, die eine quaternäre Ammoniumgruppe und wenigstens einen gegebenenfalls substituierten höheren Kohlenwasserstoffrest mit 7-22 C-Atomen, der ein Alkyl- oder Alkylarylrest sein kann, enthalten.The surface-active quaternary ammonium compounds used are the cationic surfactants described in DE-A-2 644 073, which contain a quaternary ammonium group and at least one optionally substituted higher hydrocarbon radical with 7-22 carbon atoms, which can be an alkyl or alkylaryl radical.

Die quaternären Ammoniumverbindungen liegen im Gemisch mit Toluolsulfonat oder Xylolsulfonat und den Chlorparaffinsulfonaten vor, wobei es für die besondere Wirksamkeit des Reinigungsverstärkers hinsichtlich Reinigungskraft und Schmutztragevermögen von Bedeutung ist, daß das angegebene Verhältnis von Kationtensid zu Aniontensiden, sowie das Verhältnis von Toluol- bzw. Xylolsulfonat zu Chlorparaffinsulfonaten eingehalten wird.The quaternary ammonium compounds are present in a mixture with toluenesulfonate or xylenesulfonate and the chloroparaffinsulfonates, it being important for the particular effectiveness of the cleaning enhancer with regard to cleaning power and dirt-carrying capacity that the ratio of cationic surfactant to anionic surfactants as well as the ratio of toluene or xylene sulfonate Chlorinated paraffin sulfonates is observed.

Sowohl das Kationtensid wie auch die Aniontenside liegen in Salzform vor, wobei das Gegenion beliebig sein kann, sofern es die Löslichkeit in der organischen Reinigungsflotte nicht beeinträchtigt. Bevorzugt werden die Alkali-, Ammonium- und Alkanolaminsalze.Both the cationic surfactant and the anionic surfactants are in salt form, and the counterion can be of any type provided that it does not impair the solubility in the organic cleaning liquor. The alkali, ammonium and alkanolamine salts are preferred.

Die Chlorparaffinsulfonate leiten sich bevorzugt von geradkettigen Paraffinen der Kettenlängen C12-C3o ab, wobei relativ enge Kettenlängenschnitte, z. B. C15-C18, C20-C21, C20-C24 als Ausgangsmaterial besonders geeignet sind. Die Herstellung der Chlorparaffinsulfonate erfolgt durch Sulfochlorierung der entsprechenden Paraffingemische bei erhöhten Temperaturen bis zu 120°C und anschließende Verseifung mit der gewünschten Base, vorzugsweise Natronlauge, bei 90-100°C. Die Produkte stellen im wesentlichen Gemische aus Paraffin-Monosulfonaten und Chlorparaffinen dar (Ullmanns, Enzyklopädie der technischen Chemie, 1965,16. Band, Seiten 562/563).The chloroparaffin sulfonates are preferably derived from straight-chain paraffins of chain lengths C 12 -C 3o , with relatively narrow chain length cuts , e.g. B. C 15 -C 18 , C 20 -C 21 , C 20 -C 24 are particularly suitable as starting material. The chloroparaffin sulfonates are prepared by sulfochlorination of the corresponding paraffin mixtures at elevated temperatures up to 120 ° C. and subsequent saponification with the desired base, preferably sodium hydroxide solution, at 90-100 ° C. The products are essentially mixtures of paraffin monosulfonates and chlorinated paraffins (Ullmanns, Encyclopedia of Industrial Chemistry, 1965, 16th volume, pages 562/563).

Bevorzugte Produkte enthalten 30-50 Gew.-% an Monosulfat und 4-25 Gew.-% an organisch gebundenem Chlor. Entsprechende Produkte sind im Handel erhältlich.Preferred products contain 30-50% by weight of monosulfate and 4-25% by weight of organically bound chlorine. Corresponding products are commercially available.

Der Ersatz der Petrolsulfonate durch Chlorparaffinsulfonate in den Reinigungsverstärkern der DE-A-2 644 073 hat einen entscheidenden Einfluß auf die Wirksamkeit einer wasserabstoßenden Imprägnierung, wie sie z. B. für Sport- und Wetterschutzbekleidung regelmäßig im Anschluß an die Reinigung durchgeführt wird. Überraschenderweise wird hierdurch eine wesentliche Verbesserung des Hydrophobiereffektes, wie er beispielsweise durch eine übliche Trockenhydrophobierung erzielt wird, erreicht. Hinsichtlich der Reinigungswirkung besteht kein wesentlicher Unterschied zwischen den Petrolsulfonaten und den Chlorparaffinsulfonaten, so daß mit den erfindungsgemäß zusammengesetzten Reinigungsverstärkern ebenfalls ausgezeichnete Reinigungsresultate auch bei pastellfarbigen oder weißen Textilien erreicht werden.The replacement of the petroleum sulfonates by chloroparaffinsulfonates in the cleaning boosters of DE-A-2 644 073 has a decisive influence on the effectiveness of a water-repellent impregnation such as that used, for. B. for sports and weather protection clothing regularly following the Cleaning is done. Surprisingly, this results in a substantial improvement in the hydrophobizing effect, as is achieved, for example, by conventional dry hydrophobization. With regard to the cleaning effect, there is no essential difference between the petroleum sulfonates and the chloroparaffinsulfonates, so that excellent cleaning results can also be achieved with pastel-colored or white textiles with the cleaning boosters composed according to the invention.
