Description
Verfahren zum Beschweren von Kunstseide Zusatz zum Pateut 468 o18 Im Hauptpatent 468 oi8 ist ein Verfahren zur Beschw-erung von Kunstseiden beschrieben, bei dein Metallsalzbäder verwendet -werden, die durch Zusatz von Säuren oder sauren Salzen eine erhöhte Säurekonzentration erhalten haben. Die mit derartigen Metallsalzbädern behandelte Kunstseide kann direkt in das nachfolgende Bad, das die zur Ausfällung erforderlichen Salze, Z. B. Alkaliphosphate, enthält, eingebracht werden, ohne daß ein Waschen, Absäuern oder Neutralisieren des behandelten Gutes vor dem Eintritt in das zweite Bad erforderlich ist. Auch kann man #bei mehrfachen Passagen durch Metallsalzbäder, z. B. Zinnchloridlösung, und Salzbäder, z. B. Alkaliphosphatlösungen, aus (lem Phosphatbad ohne vorheriges Waschen, Absäuern oder Neutralisieren direkt wieder in das Metallsalzbad, welches eine verhältnismäßig hohe Saurekonzentration hat, eingehen. Zur Schonung der Seide gegen den Auigriff durch die verhältnismäßig stark sauren Metallsalzbäder empfiehlt sich der Zusatz von Schutzkolloiden zum sauren Metallsalzbad oder zu der Seide vor ihrem Eintritt in das saure Metallsalzbad.Method for weighting artificial silk Addition to Pateut 468 o18 The main patent 468 oi8 describes a method for weighting artificial silk, in which metal salt baths are used which have been given an increased acid concentration through the addition of acids or acidic salts. The rayon treated with such metal salt baths can be introduced directly into the subsequent bath, which contains the salts required for precipitation, e.g. alkali metal phosphates, without the need to wash, acidify or neutralize the treated material before entering the second bath is. You can also # with multiple passages through metal salt baths, e.g. B. tin chloride solution, and salt baths, e.g. B. alkali phosphate solutions from (lem phosphate bath without previous washing, acidification or neutralization go directly back into the metal salt bath, which has a relatively high acid concentration. To protect the silk against attack by the relatively strongly acidic metal salt baths, the addition of protective colloids to the acidic metal salt bath or to the silk prior to its entry into the acidic metal salt bath.
Es wurde nun gefunden, daß man unter Benutzung des erfinderischen Gedankens des Hauptpatentes zu gleich günstigen Beschwerungsergebnissen und zu Seiden von gleichwertiger Güte gelangt, wenn man die zur Erhöhung der Skirekonzentration des Metallsalzbades erforderlichen Säuren oder sauren Salze der Kunstseide ganz oder zum Teil vor Einbringung derselben in das Metallsalzbad, gegebenenfalls zusammenmitSchutzkolloiden, einverleibt. In- diesem Falle kann die Säurekolizentration im nachfolgenden Metallsalzbade niedriger gehalten oder auf den Zusatz saurer Stoffe zu diesem Bade ganz verzichtet werden.It has now been found that using the inventive Thought of the main patent on equally favorable weighting results and on silks of equivalent quality if you increase the ski concentration acids or acidic salts of rayon required for the metal salt bath or partly before they are introduced into the metal salt bath, optionally together with protective colloids, incorporated. In this case, the acid colicentration can take place in the subsequent metal salt bath kept lower or omitted the addition of acidic substances to this bath will.
Durch die Vorbehandlung der Seide mit Säuren tritt hier ebenfalls eine Xriderung der Faser ein, die eine intensivere und gleichmäßi-ere Aufnahme der Beschwerungsmittel herbeiführt. Die Beschwerung der Kunstseide erfolgt dann durch Passieren eines oder nur ganz weniger Beschwerungsbäder, in denen die Stränge oder Gewebe nur ganz kurze Zeit zu verweilen brauchen, um in ausreichender Weise beschwert zu werden. Die Vorbehandlung mit Säure ist auch dann am Platze, wenn Beschwerungsbäder verwendet Ilverden, die außer Metallsalzen, Säuren und sauren Salzen noch die zur Ausfällung.- erforderlichen Salze, z. B. Alkaliphosphate, oder an Stelle der Säure oder der sauren Salze und zur Ausfällung erforderlichen Phosphate Phosphorsäure enthalten.By pre-treating the silk with acids occurs here as well an Xriderung of the fiber, which a more intensive and uniform absorption of the Brings about weighting agents. The artificial silk is then weighed through Passing one or only very few weight baths in which the strands or Tissues only need to linger for a very short time in order to be sufficiently weighted to become. Pretreatment with acid is also appropriate for weight baths used Ilverden, which except metal salts, acids and acid salts nor the salts required for precipitation, e.g. B. alkali phosphates, or in place the acid or acid salts and phosphates required for precipitation phosphoric acid contain.
B e i s p i e 1 Ein Mischgewebe, bestehend aus Acetat-und Viskoseseide, wird zuerst durch eine Lösung hindurchgeführt, die -im Liter 2o cm# technische Phosphorsäure und io g Äthylalkohol enthält.Example 1 A mixed fabric consisting of acetate and viscose silk is first passed through a solution which contains technical phosphoric acid and 10 g of ethyl alcohol per liter.
Das Gewebe wird ausgequetscht und dann durch ein Metallsalzbad hindurchgeführt, das aus einer 5prozentigen Chlorzinnlösung besteht.The tissue is squeezed out and then passed through a metal salt bath, which consists of a 5 percent chlorine tin solution.
Hierauf wird das Gewebe über einer Absaug .,vorrichtung vom überschüssigen Zinnchlorid befreit.The tissue is then removed from excess via a suction device Tin chloride freed.
