Die Erfindung betrifft ein Verfahren zur Herstellung eines hitzebeständigen Fasermaterials und ist dadurch gekennzeichnet, daß man unter Strukturerhaltung acetylierte Cellulose mit Dicyandiamid imprägniert. Für die Ausführung der vorliegenden Erfindung eignet sich besonders acetylierte Baumwolle oder acetylierter Zellstoff. Es kann jedoch auch regenerierte Cellulose oder anderes Cellulosematerial verwendet werden. Der Acetylierungsgrad soll vorteilhaft mindestens zwei Drittel desjenigen der Monoacetatstufe erreichen. Die Acetylierung kann nach an sich bekannten Verfahren vorgenommen worden sein.The invention relates to a method for producing a heat-resistant fiber material and is characterized in that acetylated cellulose with dicyandiamide is used while maintaining the structure impregnated. Acetylated cotton is particularly suitable for practicing the present invention or acetylated pulp. However, regenerated cellulose or other cellulosic material can also be used be used. The degree of acetylation should advantageously be at least two thirds of that reach the monoacetate stage. The acetylation can be carried out by methods known per se have been.

Die Imprägnierung mit Dicyandiamid geschieht vorteilhaft mit einer wäßrigen Lösung oder Dispersion derselben.Impregnation with dicyandiamide is advantageously carried out using an aqueous solution or dispersion the same.

So verwendet man z. B. eine o,i- bis 5°/oige wäßrige Lösung, zieht die zu imprägnierende Ware einige Male darin um und quetscht oder schwingt so stark ab, bis 0,1 bis 3% des Fasergewichtes an Dicyandiamid auf der Faser zurückbleibt und trocknet auf übliche Weise.So you use z. B. an o, i- to 5% aqueous Solution, pulls the goods to be impregnated in it a few times and squeezes or swings so much until 0.1 to 3% of the fiber weight of dicyandiamide remains on the fiber and dries in the usual way.

Das gemäß vorliegender Erfindung erhaltene Textilmaterial hat gegenüber dem unbehandelten Acetylierungsprodukt den Vorteil, wesentlich hitzebeständiger zu sein. Es eignet sich ausgezeichnetThe textile material obtained according to the present invention has compared to the untreated Acetylation product has the advantage of being much more heat-resistant. It is excellent

BeispieliExample i

Ein Baumwollgewebe, das nach Beispiel 2 der Patentschrift 525084 acetyliert wurde, wird, vor dem Trocknen während 5 Minuten bei 500 in. einer wäßrigen. i°/oigen Dicyandiamidlösung umgezogen, so abgewälzt, daß das Gewebe noch 100 °/o der Lösung, bezogen auf das Fasergewicht, zurückhält, und bei 100 bis 105 ° völlig getrocknet.A cotton fabric which has been acetylated according to Example 2 of the patent 525084 is, before drying for 5 minutes at 50 0 in. An aqueous. Removed 100% dicyandiamide solution, rolled over so that the fabric still retains 100% of the solution, based on the fiber weight, and completely dried at 100 ° to 105 °.

Nach einer 15 stündigen Hitzebehandlung bei i8d° hatte die Festigkeit des so stabilisierten, aeetylierten Gewebes nur um 4,5% abgenommen, wogegen das nicht mit Dicyandiamid behandelte Material unter den gleichen Bedingungen 620Zo seiner Festigkeit verlor.After a 15-hour heat treatment at i8d ° the strength of the thus had stabilized, aeetylierten tissue only by 4.5% decreased, whereas the material is not treated with dicyandiamide under the same conditions 62 0 Zo its strength lost.

Beispiel 2Example 2

Acetyliertes Kabelpapier, welches nach der britischen Patentschrift 525 265 hergestellt wurde und welches 35% gebundene Essigsäure enthält, wird mit einer wäßrigen Lösung von 0,1 % Dicyandiamid bei 50° während 5 Minuten umgezogen, so abgewalzt, daß das Kabelpapier noch 100% der Lösung, bezogen, auf Mas Fasergewicht, zurückhält, und bei 100 bis 105° völlig getrocknet.Acetylated cable paper, which after the British Patent 525 265 and which contains 35% bound acetic acid, is moved with an aqueous solution of 0.1% dicyandiamide at 50 ° for 5 minutes, so rolled so that the cable paper is still 100% of the Solution, based on Mas fiber weight, retains, and completely dried at 100 to 105 °.

Nach einer 15stündigen Hitzebehahdlung bei , i8oOt hat die Festigkeit der stabilisierten, aeetylierten Faserbahn um 33% abgenommen, wogegen das nicht mit Dicyandiamid behandelte Material unter den gleichen Bedingungen 6ö°/o seiner Festigkeit einbüßte.After a 15 hour Hitzebehahdlung at, Ot i8o the strength of the stabilized aeetylierten fibrous web has decreased by 33%, which is not treated with dicyandiamide material while under the same conditions 6NC ° / o forfeited its strength.

Beispiel 3Example 3

Ein monoacetyliertes Baumwollgewebe, welches nach Beispiel 2 der Patentschrift 525 084 acetyliert wurde, wird vor dem Trocknen während 5 Minuten bei 500' in einer 2%>igen wäßrigen Dicyandiamidlösung umgezogen, so abgeschwungen, daß das Gewebe noch 82 % der Lösung, bezogen auf das Fasergewicht, zurückhält, und bei 100 bis 105'0' völlig getrocknet.A monoacetylated cotton fabric, which has been acetylated according to Example 2 of patent specification 525 084, is pulled before drying for 5 minutes at 50 0 'in a 2%> strength aqueous dicyandiamide solution, swung so that the fabric still 82% of the solution, based on the fiber weight, retained, and fully dried at 100-105 '0'.

Nach einer 24stündigen Hitzebehandlung bei 187° hat die Festigkeit des stabilisierten, aeetylierten Gewebes nur um 140Zo1 abgenommen, wogegen das nicht mit Dicyandiamid nachbehandelte Material unter den gleichen Bedingungen 75 °/o seiner ursprünglichen Festigkeit verliert.After a 24 hour heat treatment at 187 ° the strength of the stabilized aeetylierten tissue has decreased by only 14 0 1 Zo, the non-post-treated with dicyandiamide material while under the same conditions 75 ° / o loses its original strength.
