Description

Verfahren zum Walken von Faserstoffen Das Walken von Geweben dient hauptsächlich der Verdickung und Verfilzung derselben. Ein erwünschter Nebeneffekt des Walkens ist die gleichzeitige Entfernung von aus dem Arbeitsprozeß stammenden Verunreinigungen, wie z: B. Rückstände von Spinn- oder Schmälzölen. Man hat bereits die Verwendung von Celluloseglykolaten, gegebenenfalls im Zusammenwirken mit anderen Substanzen, vorgeschlagen, jedoch besitzen die Celluloseglykolate Nachteile, die in ihrer Kalksalz- und Säureempfindlichkeit begründet sind.Process for fulling fibrous materials The fulling of fabrics is used mainly the thickening and matting of the same. A desirable side effect walking is the simultaneous removal of what comes from the work process Contaminants, such as residues from spinning or lubricating oils. One already has the use of cellulose glycolates, possibly in conjunction with others Substances proposed, however, the cellulose glycolates have disadvantages that are based on their sensitivity to calcium salts and acids.

Es wurde nun gefunden, daß man zu besseren Ergebnissen kommt, wenn man das Walken in Gegenwart von löslichen Cellulosesulfaten vornimmt.It has now been found that better results are obtained when the milling is carried out in the presence of soluble cellulose sulphates.

Die Herstellung der Cellulosesulfate kann auf verschiedenen Wegen erfolgen. Man kann Alkalicellulose mit Schwefelsäurehalogeniden umsetzen, man kann aber auch die Cellulose mit PyridinchlorsulfonsäureodermitAmidosulfonsäure zurReaktion bringen. Als Salze können die Salze der Alkalien, der Erdalkalien oder des Ammoniums, einschließlich seiner organischen Derivate, verwandt werden. Von besonderem Interesse können die Salze mit quaternären Ammoniumsalzen sein, da durch deren Anwesenheit außer dem Walk- auch ein Appretureffekt erzielt werden kann.Cellulose sulphates can be produced in various ways take place. You can react alkali cellulose with sulfuric acid halides, you can but also cellulose for reaction with pyridinechlorosulfonic acid or with amidosulfonic acid bring. The salts that can be used are the salts of alkalis, alkaline earths or ammonium, including its organic derivatives. Of special interest the salts can be with quaternary ammonium salts because of their presence In addition to the fulling effect, a finishing effect can also be achieved.

Die löslichen Cellulosesulfate können den Walkbädern zusammen mit anderen Walkmitteln sowie mit kapillaraktiven Stoffen zugesetzt werden, deren Anwendung eine weitgehende Reinigung von Rückständen der Spinn- und Schmälzöle erleichtert und so einen besonderen Waschprozeß erübrigt. Im übrigen wird das Walken in bekannter Weise durchgeführt.The soluble cellulose sulfates can be added to the fulling baths other fulling agents as well as with capillary-active substances are added, their application an extensive cleaning of residues of the spinning and lubricating oils facilitates and so a special washing process is unnecessary. For the rest, walking is more popular Way done.

Die Vorteile, die Cellulosesulfate gegenüber den Celluloseglykolaten auszeichnen, beruhen hauptsächlich auf deren größerer Härte-, Salz- und Säureunempfindlichkeit. Da die Cellulosesulfate nicht von Härtebildnern ausgefällt werden, entstehen keine Ablagerungen derartiger Fällungsprodukte im Gewebe. Damit erhalten die Produkte einen besseren Griff. Die große, vom pH-Wert und vom Salzgehalt der Lösung weitgehend unabhängige Löslichkeit der Cellulosesulfate erlaubt das Walken in alkalischem, neutralem und saurem Milieu bei gutem Wareneinsprung und gleichzeitig angenehmem Griff der Ware. Beispiel Ein Stück Tuch wird mit der gleichen Gewichtsmenge Wasser durchfeuchtet und anschließend auf der Walkmaschine unter Zusatz von 35 % des Tuchgewichtes einer zo/oigen NTatriumcellulosesulfatlösung, deren wäßrige zo/oige Lösung eine Viskosität von 8oo cP aufweist, gewalkt. Gewünschtenfalls kann man die Flüssigkeiten durch Zusatz von Ameisensäure noch schwach sauer oder durch Zusatz von Soda alkalisch stellen. Bereits nach rstündiger Walkzeit erhält man eine vorzügliche Ware.The advantages of cellulose sulfates over cellulose glycolates are based mainly on their greater insensitivity to hardness, salt and acid. Since the cellulose sulfates are not from Hardness components are precipitated, there are no deposits of such precipitation products in the tissue. So get the products a better grip. The big one, from the pH and the salinity of the Solution largely independent solubility of the cellulose sulfate allows fulling in an alkaline, neutral and acidic environment with good product entry and at the same time comfortable grip of the goods. Example A piece of cloth is made with the same weight Moistened with water and then on the fulling machine with the addition of 35% the weight of the cloth of ten percent sodium cellulose sulfate solution, the aqueous ten percent of which is Solution has a viscosity of 8oo cP, drummed. If desired, you can use the Liquids still slightly acidic through the addition of formic acid or through the addition make alkaline of soda. You get an excellent one after just an hour of fulling Were.
