Description

Verfahren zum Färben von Celluloseestern. Es ist bekannt, daß die bisher verwendeten sauren Farbstoffe der Anthrachinonklasse Acidylcellulose gar nicht oder nur sehr schwach anfärben.Process for dyeing cellulose esters. It is known that the acidic dyes of the anthraquinone class acidyl cellulose used so far even do not stain or stain only very weakly.

Es wurde nun gefunden, daß die monosulfierten. i # ¢-D ;amino- und Aminooxyantlirachinone, ihre Alkyl- und Arylsubstitutionsprodukte, welche die Sulfogruppe nicht in der Seitenkette, sondern in der 2- oder 3-Stellung des Anthrachinonkerns enthalten, Acetylcellulose direkt in kräftigen Tönen anfärben. Die so erhaltenen Färbungen besitzen neben guter Waschechtheit eine hervorragende Lichtechtheit.It has now been found that the monosulfated. i # ¢ -D; amino- and Aminooxyantliraquinones, their alkyl and aryl substitution products containing the sulfo group not in the side chain, but in the 2- or 3-position of the anthraquinone nucleus contain, color acetyl cellulose directly in strong shades. The so obtained In addition to good washfastness, dyeings have excellent lightfastness.

Man färbt diese Farbstoffe beispielsweise auf Acetatseide in der üblichen Weise, d. h. man löst sie in der gewünschten Konzentration in Wasser und bringt sie bei 6o bis 70° C unter Zusatz von Salzen oder Säuren ohne oder mit Schutzkolloiden in 3/.4 bis i Stunde auf die Faser. Als geeignete Farbstoffe kann man beispielsweise i # ¢-Diaminoaiithrachinon-3-sulfosäure,welche Acetatseide violett färbt, i-Oxy-q.-aminoanthrachinon-2-sulfosäure, welche violettrot färbt, und i-Phenylamino-q.-aminoanthrachinon- 3 -sulfosäure, welche Acetatseide lebhaft blau färbt, verwenden. Bei Verwendung von i-Phenylamino-q.-amino- 7- chloranthrachinon- 3-sulfosäure erhält man ein kräftiges grünstichiges Blau.These dyes are dyed in the usual way, for example on acetate silk Way, d. H. you dissolve them in the desired concentration in water and bring them at 6o to 70 ° C with the addition of salts or acids with or without protective colloids in 3 / .4 to 1 hour on the fiber. Suitable dyes can be, for example i # ¢ -Diaminoaiithraquinone-3-sulfonic acid, which dyes acetate silk purple, i-oxy-q.-aminoanthraquinone-2-sulfonic acid, which colors purple-red, and i-phenylamino-q.-aminoanthraquinone-3-sulfonic acid, which dye acetate silk vividly blue. When using i-phenylamino-q.-amino- 7-chloroanthraquinone-3-sulfonic acid gives a strong greenish blue.
