Description
<Desc/Clms Page number 1>
Verfahren zur Herstellung von Kunstseide, Bändchen, Filmen oder künstlichen Gebilden aus Viskose mit vermindertem Glanze.
Gemäss Verfahren nach Patent Nr. 119026 wird durch Zusatz organischer Basen, z. B. Alkylanilin, Chinolin zur spinnfertigen Viskose oder in irgendeinem andern Stadium in der Viskoseherstellung, z. B. bei der Sulfidierung, eine dauernde Mattierung des Fadens erhalten, wobei die Base durch die Spinnbadsäure herausgelöst wird.
Es hat sich nun gezeigt, dass wasserunlösliche Säureamide oder substituierte Säureamide, z. B.
Säureanilide, wie Kohlensäuredianilide und-dialkylanilide einen ganz überraschend guten Mattierung-
EMI1.1
herabmindern. Im übrigen ist je nach dem gewünschten Mattierungseffekt eine geringere oder stärkere Beimischung als 0, 15% an Mattierungsmittel zu wählen.
Die Zusatzkörper können auch, besonders wenn es sich um feste Körper handelt, in organischen wasserunlöslichen Mitteln gelöst zur Anwendung kommen. Zur besseren Emulgierung der reinen Produkte oder der Lösungen können Netzmittel, z. B. die im Handel als"Nekale"bezeichneten Mittel, mitverwendet werden. Weiterhin können Rohgemisehe der Säureamide oder Gemische mit organischen Basen oder andern Substanzen zur Anwendung gelangen.
Es sind zwar schon organische Stoffe mit Amido-oder Imidogruppen der Viskose zugesetzt worden.
Diese Zusätze sollten dazu dienen, die Spinnlösung haltbarer zu machen. Die zu diesem Zwecke benutzten Stoffe mussten löslich sein, um die beabsichtigte Wirkung auszulösen. Bei dem vorliegenden Verfahren sind dagegen nur unlösliche oder schwer lösliche Säureamide brauchbar.
Beispiel : Der spinnfertigen Viskose werden 0, 15% Kohlensäuredialkylanilid eingerührt. Die Verspinnung und Aufarbeitung kann in der üblichen Weise erfolgen. Es wird eine Kunstseide mit vermindertem Glanz erhalten.

Process for the production of rayon, ribbons, films or artificial structures from viscose with reduced gloss.
According to the method according to patent no. 119026, the addition of organic bases, e.g. B. alkylaniline, quinoline for ready-to-spin viscose or at any other stage in the production of viscose, e.g. B. obtained during sulfidation, a permanent matting of the thread, the base being dissolved out by the spinning bath acid.
It has now been shown that water-insoluble acid amides or substituted acid amides, e.g. B.
Acid anilides, such as carbonic acid dianilides and dialkylanilides, have a surprisingly good matting effect.
EMI1.1
diminish. In addition, depending on the desired matting effect, a lower or greater admixture than 0.15% of matting agent should be selected.
The additional bodies can also be used dissolved in organic water-insoluble agents, especially if they are solid bodies. For better emulsification of the pure products or the solutions, wetting agents, e.g. B. the means referred to in the trade as "Nekale" can also be used. Furthermore, raw mixtures of the acid amides or mixtures with organic bases or other substances can be used.
Organic substances with amido or imido groups have already been added to the viscose.
These additives should serve to make the spinning solution more durable. The substances used for this purpose had to be soluble in order to have the intended effect. In contrast, only insoluble or sparingly soluble acid amides can be used in the present process.
Example: 0.15% carbonic acid dialkylanilide is stirred into the ready-to-spin viscose. The spinning and working up can be carried out in the usual way. An artificial silk with reduced gloss is obtained.
