Description

Verfahren zum Schlichten von Kunstseide Für - die Verarbeitung auf Webstühlen bedarf dass Kunstseidegarn einer Präparierung, des sog. Schlichtens, das bezweckt, der Kunstseide :eine größere Zerreißfestigkeit zu erteilen, gleichzeitig die einzelnen Fäserchen, eines Kunstseidenfadens zusammenzukleben und den Faden überhaupt in Richtung b@esserer Verarbeitbarkeit zu beeinflussen. Bisher verwendet man für diesen Zweck aufgeschlossene Stärken, Pflanzenschleime, ferner Lösungen von Leinöl usw., wobei der Effekt zum Teil ein sehr minderwertiger ist, zum andern. Teil aber wenig erwünschte Nebenwirkungen auftreten. Diese zeigen sich vor allem darin, daß die Schlichte auf der Faser unlöslich wird, also nach dem Arbeitsprozeß nicht oder nur unvollständig entfernt werden kann, was sich in den Eigenschaften der Ware, insbesondere auch in dem Verhalten beim Färben, unliebsam bemerkbar macht.Method of Sizing Rayon For - processing on For looms, the rayon yarn requires preparation, the so-called sizing, the purpose of this is to give artificial silk: to give it greater tensile strength, at the same time to glue the individual fibers of a rayon thread together and the thread to influence at all in the direction of better processability. Used so far for this purpose opened starches, plant slimes, and also solutions of linseed oil, etc., whereby the effect is partly a very inferior, partly. Partly, however, undesirable side effects occur. These show up above all in the fact that the size becomes insoluble on the fiber, i.e. after the work process not or only incompletely can be removed, which is reflected in the properties of the goods, in particular also in the behavior during dyeing, makes them unpleasant.

Es zeigte sich nun, daß man in folgender Weise eine hervorragende Schlichtung erzielen kann. Man verwendet dazu Lösungen von wasserlöslichem Polyvinylalkohol, wie solcher seit einiger Zeit im Handel ist. An sich besitzt jedoch der Polyvinylalkohol eine zu starke Klebkraft, so daß er nur in ganz verdünntem Lösungen allein anwendbar ist, wobei er für gewisse Schlichtzwecke ausreichende Effekte erzielen läßt. Verwendet man ihn in konzentrierter Form, z. B. i : io in Wasser gelöst, so klebt er nicht nur die einzelnen Fäserchen. eines Fadens zusammen, sondern verpicht auch die einzelnen Fäden selbst, eine Wirkung, die naturgemäß nicht erwünscht ist. .Es war möglich, diese allzu hohe Klebkraft durch verschiedene Zusätze weitgehend zu verringern, ohne daß der- Schlichteffekt beeinträchtigt wurde. Als solche Zusätze empfehlen sich vor allem Fette, Fettsäuren oder ihre Alkalisalze, Wachse, Alkohole, insbesondere auch mehrwertige, Zuckerarten, aufgeschlossene Stärken, Dextrine usw. -bzw. Gemische dieser Stoffe.It has now been found that an excellent Can achieve arbitration. Solutions of water-soluble polyvinyl alcohol are used for this, as such has been in the trade for some time. However, the polyvinyl alcohol possesses per se too strong a bond, so that it can only be used in very dilute solutions alone is, whereby it can achieve sufficient effects for certain finishing purposes. Used you can use it in concentrated form, e.g. B. i: io dissolved in water, it does not stick only the individual fibrils. a thread together, but also obliges the individual Threads themselves, an effect that is naturally undesirable. .It was possible, to largely reduce this excessively high adhesive strength through various additives, without the sizing effect was impaired. As such, recommend additives especially fats, fatty acids or their alkali salts, waxes, alcohols, in particular also polyvalent, sugars, digested starches, dextrins, etc. -or. Mixtures these substances.

Beispiel a Man schlichtet Kunstseide in Strang oder Kette mit einer Flotte, die auf Zoo Teile Wasser i bis 2 Teile Polyvinylalkoholenthält. Hierbei erhält man nach dem Trocknen der Seide einen vollkommen geschlossenen Faden, der bei der Verarbeitung nicht aufflust. Beispiel 2 Man schlichtet schwerer netzbare bzw. schlecht adsorbierende Kunstseiden mit einer Flotte, die i oo Teile Wasser, 2 bis i o Teile Polyvinylalkohol und o,5 bis _3 Teile netzend wirkende alkylnaphthalinsulfonsaure oder gallensaure Salze oder andere gute Netzfähigkeit aufweisende Stoffee enthält. Auch hierbei können die Komponentenverhältnisse bzw. -konzen-' tration in weitgehendem Maße variiert werden.Example a You size rayon in a strand or chain with a A liquor that contains 1 to 2 parts of polyvinyl alcohol on Zoo parts of water. Here After the silk has dried, a completely closed thread is obtained, the does not fluff up during processing. Example 2 Arbitrates that are more difficult to network or poorly adsorbing rayon with a liquor containing 100 parts of water, 2 to 10 parts of polyvinyl alcohol and 0.5 to _3 parts of wetting alkylnaphthalenesulfonic acid or bile acid salts or other staffy showing good wetting properties. Here too, the component ratios or concentrations can largely Dimensions can be varied.

Falls der geschlichtete Faden hierbei zu hart ausfällt bzw. infolge der hohen Konzentration ein Zusammenkleben der Fäden stattfindet, setzt man der obigen Flotte noch Mittel, wie Glycerin, Seife, Emulsion von ölen, Fetten, Wachsen, Paraffin usw., sulfonierte Öle u. a. m., zu, wobei man in der Regel mit etwa, x bis 5 Teilen Zusatz auskommt. Im übrigen ist natürlich die Flotte, je nach Art der Kunstseide- (ob mehr oder weniger gedreht bzw. gezwirnt, weiter je nach Aufnahmefähigkeit usw.), entsprechend zu modifizieren. Bei Verwendung der letztgenannten. Zusätze kann die Mitbenutzung von besonderem Netzmittel meist in Wegfall kommen.If the sized thread turns out too hard or as a result The high concentration causes the threads to stick together above liquor or agents such as glycerine, soap, emulsion of oils, fats, waxes, Paraffin etc., sulfonated oils and others. m., to, where one usually with about, x to 5 parts additive gets by. Otherwise, of course, the fleet, depending on Type of rayon (whether more or less twisted or twisted, further depending on Receptivity, etc.), to be modified accordingly. When using the latter. Additions, the joint use of special wetting agents can usually be omitted.
