Description

Verfahren zum Krumpffestmachen von Wolle oder Erzeugnissen daraus Zusatz zum Patent 945 232 Gegenstand des Patents 945 232 ist ein Verfahren zum Krumpffestmachen von Wolle oder Erzeugnissen daraus, bei dem die Wolle oder deren Erzeugnisse mit wäßrigen Lösungen von Methylolverbindungen von Monoureinen in Gegenwart von Säuren behandelt werden.Process for making wool or articles thereof shrink-proof Addendum to Patent 945 232 The subject of patent 945 232 is a method of shrinking of wool or products made thereof, in which the wool or its products with aqueous solutions of methylol compounds of monoureins in the presence of acids be treated.

Es wurde nun gefunden, daß man Wolle oder Erzeugnisse daraus besser krumpffrei ausrüsten kann, wenn man sie mit wäßrigen Lösungen von Methylolverbindungen von Monoureinen, deren Herstellung in der deutschen Patentschrift 910 475 beschrieben ist, in Gegenwart von Wasserstoffperoxyd und von geringen- Mengen von Salzen mehrwertiger Schwermetalle behandelt. Gegenüber der Behandlung mit Methylolverbindungen von Monoureinen allein zeichnet sich dieses Verfahren dadurch aus, daß die erhaltenen Krumpffesteffekte auch gegen eine nachträgliche Säurebehandlung beständig sind. Außerdem ist die Wolle weitgehend beständig gegen Einwirkung von Alkalien.It has now been found that wool or products made from it are better Can make it shrink-free if you treat them with aqueous solutions of methylol compounds of monoureins, the production of which is described in German Patent 910,475 is polyvalent in the presence of hydrogen peroxide and small quantities of salts Heavy metals treated. Compared to treatment with methylol compounds of monoureins This process alone is distinguished by the fact that the anti-shrink effects obtained are also resistant to subsequent acid treatment. Besides, the wool is largely resistant to the effects of alkalis.

Als geeignete Schwermetallsalze sind bei dem vorliegenden Verfahren besonders die Salze des zweiwertigen Kupfers, z. B. Kupfersulfat,- Kupferchlorid, Kupfernitrat oder Kupferacetat, zu nennen. Aber auch Nickelsulfat, Cobaltsulfat, Zinksulfat und Cadmiumsulfat sind brauchbar. Diese Salze sollen in der Behandlungsflotte zweckmäßig in einer Konzentration von io bis ioo mg/1 vorhanden sein. Auf iooo Teile der Flotte verwendet man vorzugsweise i bis 4. Teile 4o°/oiges Wasserstoffperoxyd.Suitable heavy metal salts in the present process are especially the salts of divalent copper, e.g. B. copper sulfate, - copper chloride, Copper nitrate or copper acetate. But also nickel sulfate, cobalt sulfate, Zinc sulfate and cadmium sulfate are useful. These salts should be in the treatment liquor expediently be present in a concentration of 10 to 100 mg / l. on 1,000 parts of the liquor are preferably used from 1 to 4 parts of 40% hydrogen peroxide.

Die in dem nachstehenden Beispiel angegebenen Teile sind Gewichtsteile.The parts given in the example below are parts by weight.

Beispiel 3o bis 4o Teile Dimethylol-glyoxalmonourein werden in 998' Teilen Wasser gelöst. Hierzu gibt man noch 0,05 Teile Kupfer(II)-sulfat, 2 Teile Wasserstoffperoxyd (4o°/oig) und i2 Teile Trinatriumphosphat. In diesem Bad werden 5o Teile Wolle 30 Minuten bei 4ö bis 6o° behandelt. Hiernach wird das Bad mit Schwefelsäure auf pH =:2 eingestellt und nochmals 5 Minuten behandelt. Anschließend wird die Wolle, ohne zu spülen, geschleudert und bei etwa 70° getrocknet und dann auf iio bis i4o° während ro bis 15 Minuten erhitzt. Die so behandelte Wolle ist krumpffest. Dieser Effekt bleibt auch nach einer Säurebehandlung erhalten. Der Griff der Wolle wird durch diese Behandlung nicht nachteilig beeinflußt.Example 30 to 40 parts of dimethylol-glyoxalmonourein are dissolved in 998 parts of water. To this are added 0.05 parts of copper (II) sulphate, 2 parts of hydrogen peroxide (40%) and 12 parts of trisodium phosphate. In this bath, 50 parts of wool are treated for 30 minutes at 40 to 60 degrees. The bath is then adjusted to pH =: 2 with sulfuric acid and treated again for 5 minutes. The wool is then spun, without rinsing, and dried at about 70 ° and then heated to 10 to 14 ° for 15 to 15 minutes. The wool treated in this way is resistant to shrinkage. This effect is retained even after acid treatment. The handle of the wool is not adversely affected by this treatment.
