Description
Das Patent 199167 schützt ein Verfahren zum Färben von Wolle mit Schwefelfarbstoffen im mit Bisulfit versetzten Färbebade.The 199167 patent protects a method for dyeing wool with sulfur dyes in a dye bath mixed with bisulfite.
Es wurde nun bei weiterer Verarbeitung gefunden, daß dieses Verfahren auch zum Färben von Seide, Kunstseide, Baumwolle, Jute, Leinen, Kokosfasern, Hanf und pflanzlichen Fasern überhaupt sowie zum Färben von gemischten Gespinsten und Geweben aus diesen Fasern vorzüglich geeignet ist. Wie im Hauptpatent liegt auch hier das wesentliche Moment in der Ausnutzung der Beobachtung, daß dem schwefelalkalischen Farbbade Bisulfite in großen Mengen zugesetzt werden können, ohne daß eine Ausscheidung von Farbstoff . oder eine sonstige nachteilige Wirkung auf das Farbbad eintritt.It has now been found in further processing that this method can also be used for Dyeing of silk, rayon, cotton, jute, linen, coconut fiber, hemp and vegetable Fibers in general and for dyeing mixed webs and fabrics made from these fibers is particularly suitable. Like in Main patent, the essential factor here is the use of the observation, that bisulfites are added in large quantities to the sulfur-alkaline dye bath can without any excretion of dye. or any other adverse effect enters the dye bath.
Dieses überraschende Moment ist auch von technischen Vorteilen begleitet, denn einerseits bewirkt die neutrale Reaktion eine bessere Erschöpfung der Farbbäder, andererseits erleichtert sie ungemein die Färbearbeit, weil das Material der Färbegefäße und -apparate und — was besonders hervorzuheben ist — die Hände der Arbeiter verhältnismäßig weniger leiden, als es bei dem üblichen Verfahren im schwefelalkalischen Bade der Fall ist.This surprising moment is also accompanied by technical advantages, because on the one hand the neutral reaction causes a better exhaustion of the dye baths, on the other hand it makes it easier they immensely do the dyeing work, because the material of the dyeing vessels and apparatus and - which is particularly noteworthy - the hands of the workers suffer comparatively less than with the usual procedure is the case in a sulfur-alkaline bath.
Außerdem tritt bei der neuen Arbeitsweise der lästige und gesundheitsschädliche Geruch nach Schwefelwasserstoff nicht auf, der bei der üblichen Arbeitsweise schon Anlaß zu mancher berechtigten Klage bot.In addition, the new way of working has an annoying and unhealthy smell after hydrogen sulfide does not appear, which in the usual way of working already gives rise to offered some legitimate complaints.
Schließlich zeigt sich ein weiterer Vorteil auch in der Beschaffenheit des Färbegutes, das, weil freies Schwefelalkali nicht vorhanden ist, in vielen Fällen in seinen wertvollen textilindustriellen Eigenschaften erhalten wird.Finally, there is another advantage in the quality of the material to be dyed, This is because free alkaline sulfur is not available, in many cases in its valuable textile industry Properties is obtained.
Die Arbeitsweise ist die gleiche, wie sie für das Färben von Wolle beschrieben wurde.The procedure is the same as that described for dyeing wool.
