Description

Im Patent 752 701 ist die Nachbehandlung der bereits mit entsäuernden, entquellenden und härtenden Salzbädern bei Temperatur oberhalb 25° koagulierten Caseinfäden vorgesehen.
Die Erfindung bezieht sich dagegen auf eine Nachbehandlung der bereits bei niedrigeren Temperaturen, also nicht oberhalb 25 °, gehärteten Fäden oder Fasern. Solche Gebilde widerstehen keiner längeren Kochung, zeigen vielmehr nach dem Kochen eine wesentliche Verschlechterung ihrer Naßfestigkeit.The patent 752 701 provides for the aftertreatment of casein threads that have already been coagulated with deacidifying, de-swelling and hardening salt baths at temperatures above 25 °.
In contrast, the invention relates to an after-treatment of the threads or fibers which have already been hardened at lower temperatures, that is to say not above 25 °. Such structures do not withstand prolonged boiling, but rather show a significant deterioration in their wet strength after boiling.

Es wurde nun gefunden, daß die Kochbeständigkeit der bereits nicht oberhalb 25 °'gehärteten Fäden oder Fasern wesentlich gesteigert werden kann, wenni diese einer 5 bis 6 Stunden dauernden Nachbehandlung mit Formaldehydlösungen bei höheren Temperaturen, vorzugsweise bei 700, unterworfenIt has now been found that the cooking resistance already can not be above 25 ° 'cured filaments or fibers substantially increased the, these Wenni subjected to lasting 5 to 6 hours post-treatment with formaldehyde solutions at higher temperatures, preferably at 70 0,

AusfuhrungsbeispieleWorking examples

1. Bei niedriger Temperatur unlöslich gemachte und noch nicht gewaschene Caseinfäden werden in einem 30 bis 40 g Formaldehyd und 250g Natriumchlorid pro Liter enthaltendem Bad 5 bis 6 Stunden bei 700 behandelt.1. A low temperature insolubilized and not washed Caseinfäden be treated in a 30 to 40 g of formaldehyde and 250g of sodium chloride per liter bath containing 5 to 6 hours at 70 the 0th

2. Es wird nach Beispiel 1 verfahren, aber die Fäden werden vor der Behandlung bei hohen Temperaturen gewaschen.2. The procedure is as in Example 1, but the threads are before the treatment at high temperatures washed.

3. Es wird nach Beispiel 1 verfahren, aber die Fäden werden vor der Behandlung bei hohen Temperaturen gewaschen und getrocknet.3. The procedure is as in Example 1, but the Threads are washed and dried at high temperatures before treatment.

4- Man verfährt nach den· Beispielen i, 2 oder 3, läßt jedoch im Bad das Natriumchlorid weg.4- You proceed according to examples i, 2 or 3, but leaves out the sodium chloride in the bathroom.

An Stelle von Natriumchlorid können andere lösliche Neutralsalze verwendet werden.Other soluble neutral salts can be used in place of sodium chloride.
