Description
Patentiert im Deutschen Reiche vom 24. September 1907 ab. Längste Dauer: 17.Januar 1922.Patented in the German Empire on September 24, 1907. Longest duration: January 17, 1922.
Das Patent 200927 schützt ein Verfahren zum Ätzen von Thioindigorotfärbungen, das
dadurch gekennzeichnet ist, daß man die mit Hydrosulfit bedruckten Gewebe unmittelbar
anschließend an das Dämpfen durch ein kochendes Bad von Wasser bzw. äußerst verdünnter
Natronlauge nimmt. Bei dieser Passage werden die beim Dämpfen entstandenen
Leukoverbindungen der Farbstoffe von dem Gewebe entfernt, noch bevor sie Gelegenheit
haben, sich durch die Berührung mit der Luft wieder zu oxydieren.
. Es wurde nun gefunden, daß in diesem Verfahren das kochende Wasserbad ersetzt werden kann durch ein Bad, welches verdünnten,
schwach angesäuerten Alkohol enthält. Dieser Ersatz bietet den Vorteil, daß man die Passage nicht bei Kochtemperatur,
sondern auch bei wesentlich niederer Temperatur (40 bis 550 C.) vornehmen kann, ohne
daß dadurch die Resultate irgendwie beeinträchtigt werden. Man erhält vielmehr blendend
weiße Ätzeffekte.Patent 200927 protects a method for etching thioindigo red dyeings, which is characterized in that the fabric printed with hydrosulfite is taken immediately after the steaming through a boiling bath of water or extremely dilute sodium hydroxide solution. During this passage, the leuco compounds of the dyes formed during steaming are removed from the fabric even before they have the opportunity to re-oxidize on contact with the air.
. It has now been found that in this process the boiling water bath can be replaced by a bath which contains dilute, weakly acidic alcohol. This replacement has the advantage that you can make the passage does not at boiling temperature, but also at a much lower temperature (40 to 55 0 C.) without effecting the results are somehow impaired. Rather, you get dazzling white etching effects.
,j- Beispiel., j- example.
Der mit Thioindigorot gefärbte Stoff wird mit einer Druckfarbe bedruckt, welche im Kilogramm 120 g Hydrosulfit NF cone, enthält. Nach dem Trocknen wird im luftfreien Dämpfer bei etwa io8° gedämpft und die bedruckten Stoffe unmittelbar nach dem Dämpfen durch ein Bad genommen,' welches auf ι 1 Wasser etwa 250 ecm Alkohol und 10 ecm konzentrierte Salzsäure enthält. Die Passage dauert etwa 2 Minuten und kann, erf orderlichenfalls wiederholt werden.The fabric dyed with thioindigo red is printed with a printing ink which contains 120 g hydrosulfite NF cone per kilogram. After drying, steaming is carried out in an air-free steamer at about 10 ° and the printed materials are taken through a bath immediately after steaming which contains about 250 ecm of alcohol and 10 ecm of concentrated hydrochloric acid per 1 water. The passage takes about 2 minutes and can be repeated if necessary.
Man erhält auf diese Weise sehr schöne weiße Ätzeffekte. In der gleichen Weise können mit Thioindigoscharlach oder anderen Farbstoffen der Thioindigogruppe gefärbte Gewebe geätzt werden.Very beautiful white etching effects are obtained in this way. In the same way you can tissues dyed with thioindigo or other thioindigo group dyes to be etched.

Abänderung des Verfahrens gemäß Patent 200927 zum Ätzen von Färbungen der Thioindigorotgruppe, darin bestehend, daß man die mit der hydrosehwefligen Säure in deren verschiedenen gewerblichen Formen bedruckten und gedämpften Gewebe unmittelbar nach dem Dämpfen an- statt durch ein kochendes Bad von Wasser bzw. Wasser und Alkali hier durch ein Bad nimmt, welches verdünnten angesäuerten Alkohol enthält.Modification of the process according to patent 200927 for etching colorations the thioindigo red group, consisting in that one with the hydrosehulphurous Acid in its various commercial forms printed and steamed fabrics immediately after steaming. instead of a boiling bath of water or water and alkali Takes bath, which contains dilute acidified alcohol.
