KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Um der gefärbten mercerisirten Baumwolle, welche schon den ausgeprägten Glanz der natürlichen Seide aufweist, aufserdem noch den bekannten knirschenden Griff des Naturproductes zu verleihen, ist es allgemein üblich, die gefärbten Garne nach dem Spülen auf ein sogenanntes saures Avivirungsbad zu bringen, auf welchem die Waare bei gewöhnlicher Temperatur kurze Zeit umgezogen, sodann ohne vorhergehendes Spülen geschleudert und . getrocknet wird.The dyed mercerized cotton, which already has the pronounced sheen of the natural silk, also has the well-known crunchy feel of the natural product To impart, it is common practice to put the dyed yarns on after rinsing to bring the so-called acidic softening bath, on which the goods are at normal temperature moved for a short time, then spun without prior rinsing and. dried will.

Bisher wurden zum Aviviren benutzt: Essigsäure, Milchsäure und Weinsäure oder ein Gemisch derselben. Die Nachbehandlung der mercerisirten Waare mit Essigsäure zur Erzeugung eines knirschenden Griffes zeigt den Uebelstand, dafs der erzielte Effekt allmählich wieder zurückgeht und in verhältnifsmäfsig kurzer Zeit beim Lagern der Waare verschwindet, infolge der Flüchtigkeit der verwendeten Säure. Der widerwärtige Geruch der technischen Milchsäure verbietet ohne Weiteres in vielen Fällen die Anwendung dieser nicht flüchtigen Säure, so dafs gegenwärtig das Weinsäureverfahren wohl das verbreiteste ist, da diese Säure die genannten Uebelstände nicht zeigt.So far, the following have been used for finishing: acetic acid, lactic acid and tartaric acid or a mixture the same. The aftertreatment of mercerized goods with acetic acid for production a grinded grip shows the inconvenience that the effect obtained is gradual goes back again and disappears in a comparatively short time when the goods are stored, due to the volatility of the acid used. The disgusting smell of technical lactic acid forbids without In many cases this is also the case with the use of this non-volatile acid the tartaric acid process is probably the most common, since this acid does not show the abuses mentioned.

Nun erleiden aber bekanntlich eine grofse Anzahl von organischen Farbstoffen selbst durch organische Säuren einen mehr oder weniger intensiven Nüancenumschlag, so dafs sie von vornherein von der Verwendung zum Färben mercerisirter Baumwolle, welche avivirt werden soll, ausgeschlossen sind; aufserdem giebt es wiederum eine ganze Anzahl von organischen Farbstoffen, welche zwar bei der Behandlung für sich allein mit diesen Säuren eine kaum bemerkbare Veränderung erleiden, jedoch sobald zwei oder mehrere dieser Farbstoffe combinirt werden, beim Ansäuren eine von der ursprünglichen abweichende Nuance geben, so dafs der Färber nicht, wie dies in den meisten Fällen geschehen mufs, nach Muster färben kann.It is well known, however, that a large number of organic dyes suffer themselves a more or less intensive change of nuance through organic acids, so that from the outset from the use for dyeing mercerized cotton, which avivates should be excluded; furthermore there are again a whole number of organic dyes, which although treated on their own with these acids undergo a barely noticeable change, however, as soon as two or more of these dyes be combined, with acidification a shade deviating from the original so that the dyer does not, as must in most cases, follow Can color pattern.

Wir haben nun gefunden, dafs diese Uebelstände leicht vermieden werden können, wenn an Stelle der bisher angewendeten organischen Säuren die Borsäure verwendet wird; der knirschende Griff geht beim Lagern nicht zurück, und selbst gegen Säuren äufserst empfindliche Farbstoffe, wie Congorot, werden durch die Avivage mit Borsäure in der Nuance kaum verändert, so dafs bei dieser Nachbehandlungsmethode dem Färber eine weit gröfsere Anzahl von Farbstoffen und Farbstoffcombinationen zu dem gedachten Zweck zugänglich ist.We have now found that these evils can easily be avoided if boric acid is used instead of the organic acids previously used; the Grinding grip does not decrease when stored, and is extremely sensitive even to acids Dyes, such as congo red, are given a nuance by the finishing with boric acid hardly changed, so that with this method of aftertreatment the dyer receives a far greater number of dyes and combinations of dyes is accessible for the intended purpose.

Wir erläutern unser Verfahren durch folgendes We explain our procedure by the following

Beispiel:Example:

100 kg mercerisirtes Garn, welches mit einem beliebigen Farbstoff angefärbt worden ist, wird nach dem Spülen und Auswringen auf ein kaltes Bad gebracht, welches aus 2000 1 Wasser und 8 bis 12 kg Borsäure hergestellt worden100 kg of mercerized yarn, which with a Any dye that has been stained is used after rinsing and wringing out on one brought a cold bath, which was made from 2,000 liters of water and 8 to 12 kg of boric acid

ist; die Waare wird 1Z2 Stunde lang fleifsig umgezogen, ausgewrungen und getrocknet. Das Borsäurebad kann continuirlich benutzt werden, wenn dafür gesorgt wird, dafs der Borsäuregehalt nach jeder Avivage auf den ursprünglichen Gehalt ergänzt wird.is; the goods are carefully removed, wrung out and dried for 1 Z 2 hours. The boric acid bath can be used continuously if it is ensured that the boric acid content is replenished to the original content after each softening.
