DEUTSCHES PATENTAMTGERMAN PATENT OFFICE
Es ist bekannt, Verformungsprodukte von Polyacrylnitril und acrylnitrilhaltigen Mischpolymerisaten mit anionischen Farbstoffen (Säurefarbstoffen, Substantiven Farbstoffen, Leukoestersalzen von Küpenfarbstoffen u. dgl.) in Gegenwart von Kupfer(II)-Verbindungen und geeigneten Reduktionsmitteln zu färben. Die für diesen Zweck vorgeschlagenen Reduktionsmittel, z. B. Natriumformaldehydsulfoxylat oder Hydroxylaminsulfat, . ίο besitzen jedoch den Nachteil, die reduktionsempfindlichen Farbstoffe zu beeinflussen und die Reduktion der Kupfer (I I) -Verbindungen teilweise bis zum metallischen Kupfer zu bewirken.It is known deformation products of polyacrylonitrile and acrylonitrile-containing copolymers with anionic dyes (acid dyes, Substantive dyes, leuco ester salts of vat dyes and the like) in the presence of copper (II) compounds and suitable reducing agents to color. The ones proposed for this purpose Reducing agents, e.g. B. sodium formaldehyde sulfoxylate or hydroxylamine sulfate, . However, they have the disadvantage that they are sensitive to reduction To influence dyes and the reduction of the copper (I I) compounds partially up to effect metallic copper.
Es wurde nun gefunden, daß sich die genannten Nachteile vermeiden lassen, wenn man bei dem Verfahren zum Färben von Verformungsprodukten (Fasern oder Folien) von Polyacrylnitril und acrylnitrilhaltigen Mischpolymerisaten mittels anionischer Farbstoffe, Kupfer^II)-Verbindungen und Reduktionsmitteln als Reduktionsmittel Sulfitablauge verwendet. Dieses Reduktionsmittel liefert außerdem auch ohne besondere VorsichtsmaßnahmenIt has now been found that the disadvantages mentioned can be avoided if one in the Process for coloring molded products (fibers or foils) made of polyacrylonitrile and acrylonitrile-containing copolymers by means of anionic dyes, copper ^ II) compounds and Reducing agents used as reducing agents sulphite waste liquor. This reducing agent delivers besides, even without special precautionary measures

B. the hydroxylamine sulfate process in the interest of good equality special precautionary measures, e.g. B. the drop by drop Addition of the hydroxylamine sulfate is required, which complicates the dyeing process.
(Die Prozentzahlen beziehen sich auf das zu färbende Fasermaterial.)(The percentages relate to the fiber material to be dyed.)
ίο Man setzt mit io°/o Kupfersulfat und einer Menge von Sulfitablauge, welche 20% Trockensubstanz entspricht; ein Färbebad an, wobei sich ein pH-Wert von etwa 4 einstellt. Dann wird 5% Echtrot AV (Schultz, Farbstofftabellen, Bd. I,ίο One sets with 10% copper sulphate and an amount of sulphite waste liquor which corresponds to 20% dry matter; A dyebath at to give a p H value sets from about 4 hours. Then 5% fast red AV (Schultz, color tables, vol. I,
7. Auflage, S. 92, Nr. 206) in Wasser gelöst und dem Färbebad zugefügt. Man geht mit der Ware ein und treibt allmählich zum Kochen, wobei das Färbegut ausreichend bewegt wird. Bei Erreichen der Kochtemperatur hat sich im Färbebad ein pjj von 2 bis 3 eingestellt, der optimale Färbungen ermöglicht. Man kodht ungefähr 1. Stunde.7th edition, p. 92, no. 206) dissolved in water and added to the dyebath. You go with the goods and gradually comes to a boil, moving the material to be dyed sufficiently. Upon reaching the boiling temperature in the dyebath has reached a pjj set from 2 to 3, which enables optimal coloring. You kodht about 1 hour.
Man erhält so eine leuchtend rote Färbung.A bright red color is obtained in this way.
Statt der Sulfitablauge selbst kann mit gleichem Erfolg auch das durch Verdampfung der Ablauge erhaltene Pulver verwendet werden.Instead of the sulphite waste liquor itself, this can also be done with the same success by evaporation of the waste liquor obtained powder can be used.
