Description

Verfahren zur Erhöhung der Anfärbbarkeit von Cellulosefasern durch saure Farbstoffe Es wurde gefunden, daß man Faserstoffe aus natürlicher oder regenerierter Cellulose in .allen Verarbeitungszuständen- durch Behandeln mit Cyanamid oder seinen Salzen in ihrem Verhalten gegenüber sauren Farbstoffen weitgehend der Wollfaser angleichen kann. Vor den bekannten Verfahren dieser Art hat das neue Verfahren den Vorteil einer viel einfacheren Ausführungsart. Es genügt ein einfaches Einlegen der Faser in die Lösungen der ob.engenannten Verbindungen.Process for increasing the dyeability of cellulose fibers acidic dyes It has been found that fibers from natural or regenerated Cellulose in .all processing states - by treating with cyanamide or its Salts in their behavior towards acidic dyes largely of the wool fiber can match. Before the known methods of this type, the new method has the Advantage of a much simpler design. A simple insertion is sufficient the fiber in the solutions of the above-mentioned compounds.

Beispiel z Ein Gewebe aus Viscosekunstseide wird einige Stunden in eine 5 o/oige wässerige Lösung von Natriumcya!namid eingelegt, anschließend abgequetscht und gut gespült. Wird das so behandelte Gewebe in :eixiem sauren Färbebadmt Poncea!u 2 R (Schultz, Farbstoff tabellen, 7. Auflage, Nr. 95) gefärbt, so erhält man eine satte, rote Färbung. Ein nicht vorbehandeltes, im gleichen Bad mitgefärbtes Gewebe zeigt praktisch keine Affinität zu. dem Farbstoff.Example z A viscose rayon fabric is used in a 5% aqueous solution of sodium cyanide is inserted, then squeezed off and rinsed well. If the fabric treated in this way is in: eixiem acid dye bath Poncea! U 2 R (Schultz, dye tables, 7th edition, no. 95) colored, one obtains a rich red color. A fabric that has not been pretreated and dyed in the same bath shows practically no affinity to. the dye.

Beispiel 2 Baumwollsatin wird :einige Stunden mit einer wässerigen io%igen Lösung von Natriumcyanamid behandelt. Nach dem Abquetschen und Spülen erhält man beim Färben mit Alizarindirektblau SE (Schultz, a. a. O., Nr. 1192) eine tiefe Blaufärbung. Ein nicht vorbehandeltes Stück Baumwollsatin, im gleichen Bade m tge.färbt, ergibt fast keine Anfärbu;ng.Example 2 Cotton sateen is: a few hours with an aqueous 10% solution of sodium cyanamide treated. Receives after squeezing and rinsing when dyeing with Alizarindirektblau SE (Schultz, op. cit., no. 1192) a deep Blue discoloration. A piece of cotton sateen that has not been pretreated, dyed in the same bath, results in almost no staining.
