Description

Im Patent 902 003 ist ein Verfahren zur Veredelung umgef ällter Cellulose beschrieben, bei welchem die Cellulose miit wasserlöslichen Kondensations<produkten aus Harnstoff und bzw. odbr Thiioharnstoff und Formaldehyd und zur Härtung' des Kondensatiionsproduktes bei erhöhter Temperatur mit oxydierend wirkenden! anorganischen Säuren, oder deren Ammoniumsalzen, namentlich Ammoniumnitrat, behandelt wird.In the patent 902 003 a process for refining reprecipitated cellulose is described in which cellulose with water-soluble condensation products made from urea and / or thiiourea and formaldehyde and to harden the condensation product at increased temperature with oxidizing! inorganic acids, or whose ammonium salts, namely ammonium nitrate, are treated.

Es wurde nun gefunden, daß mam als Härtungsmittel an Stelle der freien, oxydierend wirkenden anorganischen Säuren oder ihrer Ammoniumsalze mit ähnlichem Erfolg auch solche, unter den Härtungisbedingungeni hydrolysferendle Sake der genannten Säuren verwenden kann, die andere Kationen als das Ammonium- oder das Harnstoffkation enthalten. Als solche seien vor allem die Nitrate der dreiwertigen Metalle, z. B. desAlumiiniiums und Wismuts, genannt, ferner Zink- und Cadmiumnitrat sowie die Nitrate organischer Basen, z. B. des Pyridine, Äthanolamins oder Dimethylanilins; auch Chrom- und Eisennitrat sind geeignet. Man wird derartige Salze mit farbigen und zur Komplexbildung neigenden Ionen aber nur in solchen Fällen anwenden, in denen sie zu keinen unerwünschten Nebenwirkungen führen.It has now been found that mam can be used as a hardening agent instead of the free, oxidizing inorganic acids or their ammonium salts with similar success also those under the hardening ice conditionsi hydrolysferendle sake can use the acids mentioned, the other cations as the ammonium or urea cation. The nitrates in particular are considered to be such the trivalent metals, e.g. B. of aluminum and bismuth, called, also zinc and cadmium nitrate and the nitrates of organic bases, e.g. B. of pyridine, ethanolamine or dimethylaniline; Chromium and iron nitrate are also suitable. Man However, such salts with colored ions which tend to form complexes are only found in such salts Use in cases where they do not lead to undesirable side effects.

Die Durchführung des Verfahrens erfolgt wie beim Haiuptpatent.The procedure is carried out as with the main patent.

Beispiiel ιExample ι

Zellwolligewebe wird in eilner Lösung vottioog Dimethylalharnstoff, 2 com Ammoniak, 25°/oig, iog Aluminiumnii'trat je Liter foulardmäßig behandelt. Nach dem Trocknein bei 80° witrd das Gewebe 3 Minuten auf 1300 erhitzt.Cell wool tissue is treated like a pad in a solution of dimethylalurea, 2 com ammonia, 25% aluminum nitrate per liter. After Trocknein at 80 °, the fabric witrd 3 minutes at 130 0 heated.

to Es wird ein weiches, kalander- und knitterfestes Gewebe erhallten, das; eine vorzügliche Trocken- und Naßreißfestigkek aufweist und diese Eigenschaft auch nach wiederholter Wäsche beibehält.A soft, calender- and crease-resistant fabric is obtained that; an excellent dry and having wet tensile strength and this property maintains even after repeated washing.

Beispiel 2Example 2

Bin Damenkleider&toff aus Zellwolle wird inAm women's clothes & toff made of rayon is in

einer Lösung von 120 g Ditnethylolharnstoff, 3 ecm Ammoniak, 2'5%ig, 51g Zinknitrat je Liter behandelt. Nach erfolgter Trocknung und Kondensierung beia solution of 120 g of diethylolurea, 3 ecm Ammonia, 2'5%, 51g zinc nitrate per liter treated. After drying and condensation at

λο 130° ist das Gewebe knitterfest und quellfest. Hierdurch wird es unempfindlich gegen die Bildung· von Wasserfleckan und erhält eine gesteigerte Naßreißfestägfcait. λο 130 ° the fabric is crease-proof and swell-proof. This makes it insensitive to the formation of water stains and has an increased wet tensile strength.
