Description

Verfahren zur Herstellung einer versprühbaren, kolloidalen, wäßrigen Lösung von verkleisterter Stärke Die Erfindung betrifft ein Verfahren zur Herstellung einer versprühbaren, kolloidalen, wäßrigen Lösung von verkleisterter Stärke, insbesondere zum Stärken von Wäsche.Process for the preparation of a sprayable, colloidal, aqueous Solution of gelatinized starch The invention relates to a method of manufacture a sprayable, colloidal, aqueous solution of gelatinized starch, in particular for starching laundry.

Mit derartigen Lösungen kann beispielsweise Wäsche rasch eingesprengt werden. Es entfällt dann das Auflösen der handelsüblich in fester Form vorliegenden Stärke vor der Verwendung und der damit verbundene Zeitaufwand.With such solutions, for example, laundry can be quickly blown in will. There is then no need to dissolve those that are commercially available in solid form Strength before use and the amount of time it takes.

Es ist jedoch sehr schwierig, derartige Lösungen herzustellen. Zwar ist es bekannt, Stärke unter Zusatz von Borax zu einem Kleister aufzuschließen, jedoch kann aus einem derartigen Kleister durch Verdünnen keine niedrigprozentige Lösung hergestellt werden, da derartige Lösungen nicht stabil sind, sondern sich absetzen.However, it is very difficult to make such solutions. Though it is known to break up starch with the addition of borax to form a paste, however, no low-percentage can be obtained from such a paste by diluting it Solution are produced because such solutions are not stable, but rather drop.

Durch das Verfahren nach der Erfindung werden diese Nachteile dadurch vermieden, daß Stärke in einer niedrigprozentigen, insbesondere 2,5 % wäßrigen, kolloidalen Lösung in einem Autoklav mit als Stärkeaufschlußmittel bekanntem Borax bei Temperaturen von etwa 95 bis 115' C erhitzt wird und daß der Lösung anschließend ein mehrwertiger Alkohol und/oder Forinamid zugesetzt wird.The method according to the invention avoids these disadvantages in that starch is heated in a low-percentage, in particular 2.5% aqueous, colloidal solution in an autoclave with borax, which is known as a starch digestion agent, at temperatures of about 95 to 115 ° C and that the solution then a polyhydric alcohol and / or forinamide is added.

Es wird also eine verdünnte Lösung aufgeschlossen, wodurch die durch das nachträgliche Verdünnen auftretenden Nachteile vermieden werden. Zur weiteren Stabilisierung wird der verdünnten Lösung dann nach dem Aufschließungsprozeß ein als Stärkezusatz bekannter mehrwertiger Alkohol zugesetzt.A dilute solution is therefore digested, which causes the through the subsequent dilution occurring disadvantages can be avoided. To further Stabilization is then given to the diluted solution after the digestion process polyhydric alcohol known as starch added.

Als mehrwertiger Alkohol hat sich insbesondere Glycerin als zweckmäßig erwiesen. Es können aber auch andere mehrwertige Alkohole, wie Glykol, Erythrit, Pentite, Xexite, Verwendung finden. Es ist natürlich auch möglich, mehrere dieser mehrwertigen Alkohole in Mischung untereinander zur Anwendung zu bringen.As a polyhydric alcohol, glycerine has proven to be particularly useful proven. However, other polyhydric alcohols such as glycol, erythritol, Pentite, Xexite, find use. It is of course also possible to have several of these to bring polyhydric alcohols mixed with one another to use.

Die Zugabe dieser Mittel, die insbesondere als Stabilisatoren der kolloidalen Lösung wirken, erfolgt zweckmäßig nach Abkühlen der aufgeschlossenen Stärkelösung auf etwa 601 C. Es hat sich als besonders vorteilhaft erwiesen, den Aufschluß im Autoklav bei 100 bis 105' C durchzuführen.These agents, which in particular act as stabilizers of the colloidal solution, are expediently added after the digested starch solution has cooled to about 601 ° C. It has proven to be particularly advantageous to carry out the digestion in an autoclave at 100 to 105 ° C.

Der Lösung können in bekannter Weise Konservierungsmittel zugesetzt werden, wie beispielsweise Oxybenzoesäureäthylester, Sorbinsäure oder Natriumbenzoat.Preservatives can be added to the solution in a known manner such as ethyl oxybenzoate, sorbic acid or sodium benzoate.

Die auf die erfindungsgemäße Art gewonnene Stärkelösung kann in der üblichen Weise zum Stärken von Wäschestücken oder als Appretur verwendet werden. Besonders vorteilhaft wird sie in Form von Sprühnebeln angewendet, zu deren Erzeugung handelsübliche Farbspriihpistolen oder andere Versprühvorrichtungen verwendet werden können. Hierdurch ist es möglich, die Lösung in für den Stärkeeffekt besonders günstiger, feinverteilter Form auf das C Wäschestück aufzutragen, und auch das Aufbringen der Stärkelösung in richtig dosierter Menge wird durch diese Art der Anwendung besonders erleichtert. Beispiel Es werden 25 g Stärke und 5 g Borax mit 1000 g Wasser verkleistert und in einem Autoklav 20 Minuten bei einer Temperatur von 100 bis 1051 C gehalten. Die so hergestellte Lösung wird auf 601 C abgekühlt, und es werden in sie 10 g Glycerin sowie 10 g Formamid eingerührt. Zur Konservierung wird schließlich 1 g Natriumbenzoat hinzugefügt.The starch solution obtained in the manner according to the invention can be used in the usual way for starching items of laundry or as a finish. It is particularly advantageously used in the form of spray mist, which can be produced using commercially available paint spray guns or other spraying devices. This makes it possible to apply the solution to the C laundry item in a finely divided form that is particularly favorable for the starch effect, and the application of the starch solution in correctly dosed quantities is also particularly facilitated by this type of application. EXAMPLE 25 g of starch and 5 g of borax are gelatinized with 1000 g of water and kept in an autoclave at a temperature of 100 to 1051 ° C. for 20 minutes. The solution produced in this way is cooled to 601 ° C. and 10 g of glycerol and 10 g of formamide are stirred into it. Finally, 1 g of sodium benzoate is added for preservation.
