Description

Verfahren zur Herstellung von künstlichen Gebilden -mit vermindertem Glanz Gemäß Verfahren nach Patent 539 320 wird durch Zusatz organischer Basen, z. B. Alkylanilin, Chinolin, zur spinnfertigen Viscose oder in irgendeinem anderen Stadium in der Viscoseherstellung, z. B. bei der Sulfidierung, eine dauernde Mattierung des Fadens erhalten, wobei die Base durch die Spinnbadsäure herausgelöst wird.A process for the production of artificial structures -with reduced gloss According method according to Patent 539 320 by the addition of organic bases, for. 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 is dissolved out by the spinning bath acid.

Es hat sich nun gezeigt, daß wasserunlösliche Säureamide oder substituierte Säureamide, z. B. Säureanilide wie Kohlensäuredianilide und -dialkylanilide, einen ganz überraschend guten Mattierungseffekt geben, so daß bereits Zusatzmengen von etwa o,15 % sehr beträchtlich den Glanz von Kunstseide herabmindern. Im übrigen ist je nach dem gewünschten Mattierungseffekt eine geringere oder stärkere Beimischung als 0,15 % an Mattierungsmitteln zu wählen.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, give a very surprisingly good matting effect, so that even amounts of about 0.15% reduce the shine of rayon very considerably. Furthermore, depending on the desired matting effect, a lower or higher admixture than 0.15% of matting agents should be selected.

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. isobutylnaphthalinsulfonsaures Natrium, mitverwendet werden. Weiterhin können Rohgemische der Säureamide oder Gemische mit organischen Basen zur Anwendung gelangen. Beispiele: 1. Der spinnfertigen Viscose werden 0,15 °/o Kohlensäuredialkylanilide eingerührt. Die Verspinnung und Aufarbeitung kann in der üblichen Weise erfolgen. Es wird eine Kunstseide mit vermindertem Glanz erhalten.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. isobutylnaphthalenesulfonic acid sodium, can also be used. Furthermore, crude mixtures of the acid amides or mixtures with organic bases can be used. Examples: 1. 0.15 % carbonic acid dialkylanilides are stirred into the ready-to-spin viscose. The spinning and work-up can be carried out in the usual way. An artificial silk with reduced gloss is obtained.

2. Dem zur Xanthierung der Alkalicellulose verwendeten Schwefelkohlenstoff werden pro Zoo Kilo Zellstoff q. Kilo Athylacetanilid zugesezt und das Xanthat zur Viscose mit 7,5 °/o Zellstoff gelöst. Wird die so hergestellte Viscose in den üblichen mineralsauren Fällbädern versponnen, so weisen die erhaltenen Fäden einen stark reduzierten Glanz auf.2. The carbon disulfide used to xanthate the alkali cellulose per zoo kilograms of pulp q. Kilo of ethylacetanilide added and the xanthate for Viscose dissolved with 7.5% pulp. If the viscose produced in this way is in the usual spun in mineral acid precipitation baths, the threads obtained have a strong appearance reduced gloss on.

Statt reinem Äthylacetanilid kann auch das bei seiner Herstellung anfallende noch flüssige Rohprodukt verwendet «erden.Instead of pure ethyl acetanilide, this can also be used in its manufacture accruing still liquid crude product used «earth.
