Description

Verfahren zum Mercerisieren von Textilien Zur Mercerisierung von Textilien werden in der Regel Lösungen von fixen Alkalien verwendet, die zur Vermeidung der Beschädigungen der Faser nach der Durchtränkung der Textilien möglichst rasch und vollständig wieder ausgewaschen werden müssen. Dieses Auswaschen erfordert sehr sorgfältiges und gleichmäßiges Arbeiten und bedingt einen erheblichen Verlust an Mercerisationsmitteln.Process for mercerising textiles For mercerising textiles As a rule, solutions of fixed alkalis are used to avoid the Damage to the fiber as quickly and as quickly as possible after the textiles have been soaked must be completely washed out again. This washing out takes a lot careful and even work and causes a considerable loss Mercerizing agents.

Es wurde nun gefunden, daß auch flüssiges Ammoniak eine mercerisierende Wirkung auf Cellulose, wie Baumwolle oder Viskosekunstseide, ausübt. Die Wirkung des flüssigen Ammoniaks ist zwar wesentlich milder als die der Alkalilauge; aber diese schwächere Wirkung hat den Vorteil, daß nicht so leicht eine Beschädigung der Faser eintritt und daß die Entfernung des Mercerisationsmittels von der Faser nicht mit gleicher Schnelligkeit und Präzision durchgeführt werden muß.It has now been found that liquid ammonia also has a mercerizing effect Has an effect on cellulose such as cotton or rayon rayon. The effect the liquid ammonia is much milder than that of the alkali; but this weaker effect has the advantage that damage is not so easy the fiber enters and that the removal of the mercerizing agent from the fiber does not have to be carried out with the same speed and precision.

Da das flüssige Ammoniak sehr leicht durch Verdampfen, besonders im Vakuum, von den behandelten Materialien entfernt werden kann, ist eine Beschädigung durch das Mercerisationsmittel so gut wie ausgeschlossen. Auch die Wiedergewinnung des Mercerisationsmittels ist wesentlich leichter durchführbar, als dies bei den fixen Alkalien geschehen kann.Since the liquid ammonia very easily evaporates, especially in the Vacuum, from which the treated materials can be removed, is damaging as good as excluded by the mercerizing agent. Recovery too of the mercerizing agent is much easier to carry out than with the fixed alkalis can happen.

Unter Mercerisieren im Sinne dieses Verfahrens wird nicht nur die Vergütung der Baumwolle, die in der Erhöhung des Glanzes und der Festigkeit besteht, sondern auch die Vergütung der Kunstseide, besonders der Viskosekunstseide und der hochfesten Viskosekunstseide, verstanden, bei der eine Mercerisation zur Erhöhung der Dehnung und der Anfärbbarkeit durchgeführt wird.Mercerizing in the sense of this process is not just the Compensation of cotton, which consists in increasing the gloss and strength, but also the remuneration of artificial silk, especially viscose artificial silk and the high-strength viscose rayon, understood in which a mercerization to increase elongation and dyeability is carried out.

Die Vergütung von Kunstseidesträngen oder kunstseidenen Geweben durch Nachbehandlung mit flüssigem Ammoniak kann beispielsweise so geschehen, daß die Stränge bzw. Gewebe ohne oder unter gelinder Spannung einige Minuten in flüssiges Ammoniak getaucht werden. Ist die Hauptmenge des Ammoniaks von der Seide abgetropft oder abgequetscht, dann kann der Rest des Ammoniaks durch Absaugen im Vakuum rasch entfernt werden. Wird bei gewöhnlichem Druck gearbeitet, so muß die Temperatur des Ammoniaks selbstverständlich unter dem Siedepunkt des Ammoniaks liegen.The remuneration of rayon strands or rayon fabrics through Post-treatment with liquid ammonia can be done, for example, so that the Strands or tissue with or without tension in liquid for a few minutes Ammonia. The main amount of ammonia has drained from silk or squeezed off, then the rest of the ammonia can be quickly removed by suction in a vacuum removed. If normal pressure is used, the temperature of the Ammonia are of course below the boiling point of ammonia.

Eine gewöhnliche Kunstseide mit der Festigkeit/Dehnung von 167/13,6 hatte nach der Mercerisierung folgende , Reißwerte 162/18,2. Eine hochfeste Kunstseide mit den Reißwerten 312/6,,1 hatte nach Mercerisierung unter gelinder Spannung die Reißwerte 324/84. Außer der Erhöhung der Dehnung war auch die Anfärbbarkeit der Kunstseide nach der Mercerisierung verbessert.An ordinary rayon with a strength / elongation of 167 / 13.6 had the following tear values after mercerization 162 / 18.2. One high-strength rayon with tear values 312/6,, 1 had under the tensile strength is 324/84. Besides the increase in elongation was also the dyeability of the rayon improves after mercerization.
