Description

Verfahren zur Herstellung von Kunstfäden, Filmen, Bändchen usw. aus, insbesondere ungereifter, Viskose Die Verwendung von aromatischen Sulfosäuren als Badzusatz zur Erzeugung glänzender Kunstfasern aus Viskose ist bereits bekannt.Process for the production of synthetic threads, films, ribbons, etc. from, especially unripened, viscose The use of aromatic sulfonic acids as Bath additive for producing shiny synthetic fibers from viscose is already known.

Es wurde nunmehr gefunden, daß auch die wasserlöslichen und leimfällenden Sulfosäuren aus Mineralölen, aliphatischen Teeren und Teerölen. beispielsweise wasserlösliche Bestandteile sogenannter Säureharze, sich vorzüglich als Spinnbadzusatz bei der Fällung von Viskoselösungen eignen. Der technische Fortschritt gegenüber dein Vorbekannten liegt darin, daß gemäß vorliegender Erfindung als Badzusätze leicht zugängliche aliphatische Sulfosäuren benutzt werden und außerdem ein Salzzusatz zu den Spinnbädern nicht erforderlich ist.It has now been found that the water-soluble and glue-precipitating Sulphonic acids from mineral oils, aliphatic tars and tar oils. for example water-soluble Components of so-called acid resins, excellent as a spin bath additive in the Suitable for the precipitation of viscose solutions. The technical progress compared to what you already knew is that, according to the present invention, easily accessible bath additives aliphatic sulfonic acids are used and a salt addition to the spinning baths is not required.

Beispiele: 1. Verwendet wird ein Spinnbad, welches 1o°/" Schwefelsäure und 6°/o Braunkohlenteersulfosäure enthält. Den Spinnbädern können auch Salze, besonders Sulfate, bis etwa 15°/0 hinzugefügt werden. Mit diesem Bad erhält man bei Verwendung von ohne jede künstliche Reife hergestellter Viskose schöne glänzende und sehr feste Fasern.Examples: 1. A spinning bath is used which contains 10% sulfuric acid and contains 6% lignite tar sulphonic acid. The spinning baths can also contain salts, especially Sulphates until about 15% are added. With this bath you get when using from viscose produced without any artificial ripeness, beautiful shiny and very firm Fibers.

2. Verwendet wird ein Bad mit 13°o Schwefelsäure und 8°/o einer Maschinenölsulfosäure. Zur Herstellung der verwendeten Maschinenölsulfosäure wird vorzugsweise ein Maschinenöl von etwa folgenden Konstanten verwendet: Spezifisches Gewicht o,929, Viskosität bei 50° 5, Flammpunkt z82°, Brennpunkt z12°. Die Sulfurierung erfolgt bei Zimmertemperatur mit Schwefelsäuremonohydr at.2. A bath containing 13% sulfuric acid and 8% machine oil sulphonic acid is used. A machine oil is preferably used to produce the machine oil sulfonic acid used used by approximately the following constants: specific gravity o.929, viscosity at 50 ° 5, flash point z82 °, focal point z12 °. The sulfurization takes place at room temperature with sulfuric acid monohydrate.
