Abstract
Die Erfindung betrifft ein Verfahren zur Stabilisierung der Schweissechtheit nach hydrothermischer Behandlung von kationisch gelgefaerbten Polyacrylnitrilfaserstoffen. Ziel und Aufgabe der Erfindung ist es, Moeglichkeiten aufzuzeigen, die im Rahmen des technologischen Regimes der Nassspinntechnologie dem Faserkabel Eigenschaften verleihen, die eine stoerungsfreie Weiterverarbeitung garantieren und den Erhalt der Schweissechtheit nach hydrothermischen Daempfprozessen sichern. Dies wird erreicht, wenn zur antistatischen Ausruestung des mit kationischen Farbstoffen gelgefaerbten Faserkabels ein spezielles amphoteres Praeparationsmittel in bekannter Weise eingesetzt wird.The invention relates to a process for stabilizing the fastness to perspiration after hydrothermal treatment of cationically gel-dyed polyacrylonitrile pulp. The aim and the object of the invention is to show possibilities which, within the framework of the technological regime of wet-spinning technology, impart properties to the fiber cable which guarantee a trouble-free further processing and ensure the preservation of the perspiration fastness after hydrothermal dipping processes. This is achieved if a special amphoteric preparation is used in a known manner for the antistatic equipment of the fiber-dyed with cationic dyes fiber cable.

starkes Anbluten der Begleitgewebe. Dieses Ausbluten wird durch chemisch-physikalische Wechselwirkungen dos Tensids mit dem Farbstoff hervorgerufen. Der nicht echt chemisch gebundene kationische Farbstoff wird von dem anionischen Tensid durch den Dämpfprozeß an die Faseroberfläche transportiert und führt so zu den schlechten Schweißechtheiten.severe bleeding of the accompanying tissues. This bleeding is caused by chemical-physical interactions of the surfactant with the dye. The non-chemically bonded cationic dye is transported from the anionic surfactant to the fiber surface by the steaming process, thus resulting in poor perspiration fastnesses.

Das gewaschene gelfeuchte Kabel wurde zur Erzielung einer Färbung mittlerer Farbtiefe in einem essigsauren Bad pH-Wert 4,5 mit 4,5g/l Crypurgelb 5GL und 1,05g/l Maxiionblau 5GD unter Spannung kontinuierlich gefärbt.made of 3,4dtex. The washed, gel-wet cable was dyed continuously under tension to give medium color depth in an Acetic Acid Bath pH 4.5 with 4.5 g / L Crypur Yellow 5GL and 1.05 g / 1 Maxiion Blue 5GD.
