Description

Verfahren zur Erhöhung der Anfärbbarkeit von Baumwollfasern Bei Mischgeweben, die aus Baumwolle und Kunstseiden aus regenerierter Cellulose bestehen, macht die Gleichfärbung der beiden Textilfasern bekanntlich Schwierigkeiten. Diesem Übelstande hilft man durch eine Vo"rbehandlung des Gewebes oder der Baumwolle mit Alkalilaugen ab, denen man zur Verbesserung der Wirkung auch schon Eiweißstoffe oder deren Abbauprodukte zugesetzt hat.Process to increase the dyeability of cotton fibers In mixed fabrics, which consist of cotton and rayon from regenerated cellulose, makes the Identical coloring of the two textile fibers is known to be difficult. This evil one helps by pre-treating the fabric or cotton with alkaline solutions from which one already has proteins or their breakdown products to improve the effect added.

Diese Vorbehandlung mit Alkalilaugen, sei es ohne Schutzkolloide oder mit Schutzkolloiden, zeigt aber den Nachteil, &ß die Baumwolle stark einschrumpft, so daß man gezwungen ist, durch entsprechende Streckbehandlung die Stränge oder Gewebe wieder auf ihre ursprüngliche Länge oder Breite zu bringen, wodurch vielfach ,ein unerwünschter Glanz ,auf der Faser erzeugt wird.This pretreatment with alkaline solutions, be it without protective colloids or with protective colloids, but has the disadvantage that the cotton shrinks significantly, so that one is forced, by appropriate stretching treatment, the strands or Bringing tissue back to its original length or width, thereby multiplying , an undesirable sheen, is created on the fiber.

Es wurde nun gefunden, daß Kalilauge, in der Glukose, Dlextrin oder lösliche Stärke gelöst sind, imstande ist, das durch .die Laugenbehandlung bedingte Einschrumpfen des Baumwollfadens zu verhindern, wenn die Flotte mindestens je zo% Kaliumhydroxyd und Zusatzstoff enthält und bei mindestens 35' C auf die Faser zur Einwirkung gelangt.It has now been found that potassium hydroxide, in the glucose, or dlextrin soluble starch are dissolved, is capable of that caused by .the lye treatment To prevent the cotton thread from shrinking if the liquor is at least zo% Contains potassium hydroxide and additive and acts on the fiber at at least 35 ° C Influence.

Natronlauge oder Gemische von Natronlauge und Kalilauge mit oder ohne Schutzkolloid in den verschiedensten Konzentrationen lassen dagegen bei kalter oder warmer Behandlung Baumwolle einschrumpfen.Caustic soda or mixtures of caustic soda and potassium hydroxide with or without Protective colloid in various concentrations, on the other hand, can be used when cold or heat shrink cotton.

Beispiel Ein Mischgewebe aus Baumwolle und Cellulosekuns.tseide wird in einer Kalilauge, die 15% Kaliumhydroxyd und 2o % Glukose enthält, bei 5o' C etwa 5 Minuten behandelt. Darauf wird mit Wasser gespült, gegebenenfalls nach dem Wässern mit verdünnter Säure erbgesäuert und dann gefärbt. Es kann auch nach der Laugenbehandlung abgequetscht, gespült und dann unmittelbar gefärbt werden. Bei dieser Behandlung läuft das Gewebe ,nicht sein, und es erübrigt sich, das Gewebe ,nachher auf dem Spannrahmen wieder auf die ursprüngliche Breite zu spannen.Example A mixed fabric made of cotton and cellulose synthetic silk is used in a potassium hydroxide solution, which contains 15% potassium hydroxide and 20% glucose, at 5o'C about Treated for 5 minutes. It is then rinsed with water, if necessary after soaking acidified with dilute acid and then colored. It can also be used after the lye treatment squeezed off, rinsed and then stained immediately. In this treatment the fabric runs, not its, and it is superfluous, the fabric, afterwards on the Tension the frame back to the original width.
