Tag der Anmeldung: 9. Dezember 1953 Bekänntgemacht am 23. Februar 1956Registration date: December 9, 1953 Announced on February 23, 1956
Gegenstand der Patentanmeldung B 20947 IVc/8 k 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.The subject of patent application B 20947 IVc / 8 k is a method of making it shrink-proof of wool or products made thereof, in which the wool or its products with aqueous solutions of methylol compounds of monoureins are treated in the presence of acids.
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 can be made more shrink-free, if you treat them with aqueous solutions of methylol compounds of monoureins, their production is described in German Patent 910 475, in the presence of hydrogen peroxide and treated by small amounts of salts of polyvalent heavy metals. Opposite to the treatment with methylol compounds of monoureins alone distinguishes this process characterized in that the anti-shrink effects obtained are also resistant to subsequent acid treatment are. In addition, 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 10 bis 100. mg/1 vorhanden sein.Particularly suitable heavy metal salts in the present process are the salts of divalent copper, e.g. B. copper sulfate, copper chloride, copper nitrate or copper acetate. But nickel sulfate, cobalt sulfate, zinc sulfate and cadmium sulfate can also be used. These salts should expediently be present in the treatment liquor in a concentration of 10 to 100 mg / l.

Auf 1000 Teile der Flotte verwendet man vorzugsweise ι bis 4 Teile 40°/oiges Wasserstoffperoxyd. Die in dem nachstehenden Beispiel angegebenen Teile sind Gewichtsteile.It is preferred to use for 1000 parts of the liquor ι up to 4 parts of 40% hydrogen peroxide. The ones given in the example below Parts are parts by weight.
30 bis 40 Teile Dimethylol-glyoxalmonourein werden in 998 Teilen Wasser gelöst. Hierzu gibt man noch 0,05 Teile Kupfer(II)-sulfat, 2 Teile Wasserstoffperoxyd (404VoIg) und 12 Teile Trinatriumphosphat. In diesem Bad werden 50 Teile Wolle 30 Minuten bei 40 bis 6o° behandelt. Hiernach wird das Bad mit Schwefelsäure auf pjj = 2 eingestellt und nochmals 5 Minuten behandelt. Anschließend wird die Wolle, ohne-zu spülen, geschleudert und bei etwa 70° getrocknet und· dann auf 110 bis 1400 während 10 bis 15 Minuten erhitzt. Die so behandelte Wolle ist krumpffest. Dieser Effekt bleibt auch nach einer Säurebehandlung erhalten. Der Griff der Wolle wird durch ao diese Behandlung nicht nachteilig beeinflußt.30 to 40 parts of dimethylol-glyoxalmonourein are dissolved in 998 parts of water. For this purpose, are 0.05 parts of copper (II) sulfate, 2 parts of hydrogen peroxide (40 Voig 4) and 12 parts of trisodium phosphate. In this bath, 50 parts of wool are treated for 30 minutes at 40 to 60 °. The bath is then adjusted to pjj = 2 with sulfuric acid and treated again for 5 minutes. Thereafter, the wool to no-rinse is spun and then heated at about 70 ° · and dried at 110 to 140 0 for 10 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.
