Description

  

  Verfahren zur Herstellung eines neuen     Zellulosederivates.       Es wurde gefunden, dass die     Halogen-          cyane,    wie zum Beispiel Brom- oder     Chlor-          cyan,    mit Zellulose, welche vorher mit einem  Alkali, wie     Atzalkalilaugen    oder Pottasche  lösung, behandelt worden ist, unter Bildung  eines neuen Produktes reagieren, welches  sich durch eine vortreffliche Affinität zu  sauren Farbstoffen auszeichnet.  



  Das     Produkt    kann als Rohstoff zur Her  stellung von Textilfasern verwendet werden.  Indessen wird der Schutz für das angegebene  Verfahren nur soweit beansprucht, als es  sich nicht um eine für die Textilindustrie  in Betracht kommende Behandlung von Tex  tilfasern zum Zwecke von deren Veredlung  handelt.  



  <I>Beispiel 1:</I>  Man imprägniert 10 Teile Baumwolle in  10 %     iger    alkoholischer Natronlauge, presst  aus und behandelt das Garn in einer Lösung  von 5 bis 10 Teilen Bromcyan in Benzol  in der Kälte. Man spült in heissem Wasser  und trocknet.    <I>Beispiel 2:</I>  Man imprägniert 10 'heile Zellulose in  10%iger alkoholischer \     atronlauge,    presst  ab und behandelt das Material in einer Lö  sung von 5 bis 10 Teilen Bromcyan in Ben  zol in Gegenwart von organischen Basen, wie       Diäthylamin,        Diäthyläthylendiamin.        Piperi-          din    und andere. Man spült in heissem Was  ser und trocknet.  



  <I>Beispiel 3:</I>  Man imprägniert 10 Teile Baumwolle in  10%iger alkoholischer Natronlauge, presst  aus und behandelt in einer Lösung von  bis 10 Teilen Chlorcyan in Benzol in der  Kälte. Hierauf wird heiss gespült und ge  trocknet.  



  <I>Beispiel I:</I>  Man imprägniert 100 Teile Zellulose in  40%iger wässeriger     Pottaschelösung,    presst  ab und behandelt die Ware in einer Lösung  von 30 Teilen     Bromcyan    in Benzol in der  Kälte. Man spült in heissem Wasser und  trocknet.



  Process for the production of a new cellulose derivative. It has been found that the halocyanes, such as bromocyan or chlorocyan, react with cellulose, which has previously been treated with an alkali, such as caustic alkali or potash solution, to form a new product which is replaced by a excellent affinity for acidic dyes.



  The product can be used as a raw material for the manufacture of textile fibers. However, protection for the specified process is only claimed insofar as it is not a treatment of textile fibers for the textile industry for the purpose of their finishing.



  <I> Example 1: </I> 10 parts of cotton are impregnated in 10% strength alcoholic sodium hydroxide solution, pressed out and the yarn is treated in the cold in a solution of 5 to 10 parts of cyanogen bromide in benzene. Rinse in hot water and dry. <I> Example 2: </I> 10 'intact cellulose is impregnated in 10% alcoholic lye, pressed and the material is treated in a solution of 5 to 10 parts of cyanogen bromide in benzene in the presence of organic bases, such as Diethylamine, diethylethylenediamine. Piperidine and others. You rinse in hot water and dry.



  <I> Example 3: </I> 10 parts of cotton are impregnated in 10% strength alcoholic sodium hydroxide solution, pressed out and treated in the cold in a solution of up to 10 parts of cyanogen chloride in benzene. This is followed by hot rinsing and drying.



  <I> Example I: </I> 100 parts of cellulose are impregnated in 40% strength aqueous potash solution, pressed and the goods are treated in the cold in a solution of 30 parts of cyanogen bromide in benzene. Rinse in hot water and dry.
