Description

Verfahren zum Appretieren von Kunstseidefäden Es wurde gefunden, daß man Kunstseidefäden eine rauhe und leicht klebrige Oberfläche erteilen kann, indem man diese mit Lösungen behandelt, die aus Aluminiumphosphat, Oxalsäure und Wasser oder aus einem wasserlöslichen Aluminiumsalz, einer etwa äquivalenten Menge eines wasserlöslichen Phosphats wie Natriumphosphat, Oxalsäure und Wasser bereitet worden sind und deren Acidität zweckmäßigerweise, z. B. mit Ammoniak oder Natriumacetat, abgestumpft worden ist.Method of sizing rayon threads It has been found that you can give rayon threads a rough and slightly sticky surface by adding these are treated with solutions made up of aluminum phosphate, oxalic acid and water or from a water-soluble aluminum salt, an approximately equivalent amount of one water-soluble phosphate such as sodium phosphate, oxalic acid and water have been prepared are and their acidity expediently, for. B. with ammonia or sodium acetate, has been blunted.

So appretierte Kunstseidefäden können vor allem zur Herstellung schiebefester Kunstseidegewebe dienen, wobei sie lediglich als Schußfäden verwendet zu werden brauchen.Artificial silk threads finished in this way can mainly be used to make them more slip-resistant Rayon fabrics are used, whereby they are only used as weft threads to need.

Es ist also auf diese Weise" möglich, eine sonst übliche Naßbehandlung kunstseidener Gewebe nach Verlassen des Webstuhles zum Zwecke des Schiebefestmachens, die in manchen Fällen stören kann, zu umgehen.In this way it is "possible, an otherwise customary wet treatment Artificial silk fabric after leaving the loom for the purpose of securing it to slide, which in some cases can be annoying to work around.

Außerdem eignen sich erfindungsgemäß behandelte Kunstseidefäden für Umwicklungen aller Art, z. B. auf blanken oder bereits isolierten elektrischen Leitern. Solche Umwicklungen verschieben sich nur schwer, auch dann, wenn die Umspinnung nicht sehr fest ist.In addition, rayon threads treated according to the invention are suitable for Wraps of all kinds, e.g. B. on bare or already insulated electrical conductors. Such wraps move only with difficulty, even if the wrapping is not very firm.

Beispiel Man taucht Kunstseidegarn, das als Schußgarn für die Anfertigung kunstseidener Gewebe vorgesehen ist, kurze Zeit in eine wäßrige Lösung, die im Liter 5,5 g wasserfreies Aluminiumphosphat und 4,3 g kryst. Oxalsäure enthält, trocknet und schießt das Garn ein.Example One dips rayon yarn, which is used as a weft yarn for production Artificial silk fabric is provided for a short time in an aqueous solution containing liters 5.5 g anhydrous aluminum phosphate and 4.3 g kryst. Contains oxalic acid, dries and shoot the yarn.

Vorteilhaft stumpft man die obige Lösung vor ihrer Anwendung durch Zusatz beispielsweise von etwas Annnoniak oder Natriumacetat, gegebenenfalls bis zum Auftreten eines Niederschlages, auf einen niedrigen Säuregrad bis zu pii = 6 ab.The above solution is advantageously blunted before it is used Addition for example of some annonia or sodium acetate, if appropriate until precipitation occurs, to a low degree of acidity down to pii = 6 from.
