Description
Verfahren zur Herstellung eines zur Veredlung künstlicher Textilien, insbesondere Azetatseide, dienenden beständigen Mittels. Auf dem Gebiete der Textilstoffe, insbe sondere der künstlichen Textilien, ist es zur Erhöhung der Widerstandsfähigkeit gegen die Manipulationen in der Weberei und Wir kerei bekanntlich notwendig, die Fäden mit einer Deckenschicht zu versehen, welche die Einzelfasern aneinanderklebt und dem Faden einen mechanischen Schutz bietet.
Diese Handlung wird Schlichten genannt und hat bekanntlich nicht nur die Aufgabe, die einzelnen, den Faden bildenden Fasern. unter sich zu verkleben, sondern auch den Faden selbst gegen die mechanischen Bean spruchungen, welchen er im Fertigungsgange ausgesetzt ist, zu schützen. Die Schlichte muss genügend elastisch sein, um sich den Verformungen des Fadens ohne Risse anzu passen, und sich mit einfachen Mitteln voll ständig entfernen lassen, damit sie beim nachfolgenden Färben und Veredeln des Ge webes keinen schädlichen Einfluss ausüben kann.
Um dieses Ziel zu erreichen, werden be kanntlich verschiedene polymere oder poly- merisierbare Stoffe, wie Leinöl, Amide, tierische und vegetabilische Gelatine, oder < euch synthetische Polymere angewandt.
Im besonderen Falle der Azetatseide, bei welcher neben einem geringen Wasserauf- nahmevermögen des Fadenstoffes auch eine grössere oder kleinere, zur Bekämpfung der statischen Elektrizität notwendige blmenge vorhanden ist, hat sich die Schlichte auf Grund von in organischen Lösungsmitteln aufgelöstem oder in Wasser emulgiertem Leinöl, vorzugsweise von wässrigen Klebstoff lösungen, allgemein eingeführt.
Wird-bei Azetatseide das Schlichten auf Kettschlichtmaschinen ausgeführt, so kann das Textilmaterial auch mit wasserlöslichen Stoffen verklebt werden, während beim Strangschlichten wasserlösliche Stoffe im allgemeinen nicht verwendet werden können.
Infolge des geringen Eindringvermögens der wässrigen Lösungen in das Fadeninnere werden an Stelle der den Faden bildenden Einzelfasern die Fäden selbst aneinanderge- klebt, wodurch sich das für die weitere Ver arbeitung notwendige Winden der Stränge auf die Spulen äusserst kostspielig und schwierig gestaltet.
Es wurde nun gefunden, dass sich wässrige Lösungen tierischer und vegetabilischer Kolloide beim Schlichten auch strangförmi- ger Azetatseide vollkommen eignen, wenn. diesen Lösungen ein Stoff zugesetzt wird, der die Fähigkeit besitzt, den Klebstoff in das Innere des Fadens zu tragen.
Es wurde nun gefunden, dass sehr zufrie denstellende Ergebnisse erzielt werden, wenn als Eindringmittel einwertige, bis zu drei Kohlenstoffatome enthaltende Alkohole der Fettreihe mit verzweigter oder unverzweigter Kette verwendet werden.
Es wird auf diese Weise ein vollkomme nes Schlichten der Einzelfasern bewerkstel ligt, ohne die einzelnen Fäden unter sich zu verkleben, die dabei mit einem filmartigen, geschmeidigen und mechanisch widerstands fähigen Überzug versehen werden, welcher das Garn gegen die bei der nachfolgenden Verarbeitung auftretenden Beanspruchungen schützt.
Gegenstand des Patentes ist ein Verfahren zur Herstellung eines zur Veredlung künst licher Textilien und besonders Azetatseide dienenden beständigen Mittels, dadurch ge kennzeichnet, dass man einer Lösung eines organischen Kolloides einen einwertigen Al kohol der Fettreihe mit höchstens drei Koh- lenstoffatomen einverleibt.
Nach diesem Verfahren wird ein wesent licher wirtschaftlicher und praktischer Vor teil erreicht, denn die durch das Leinöl ge bildete Haut kann unter gewissen Umständen verschiedenartige Übelstände verursachen dadurch, dass sich die Oxydationsprodukte des Leinöls sehr fest auf dem Faden ansetzen, was hingegen bei Verwendung von tierischen Geladnen nicht der Fall ist, da deren Film durch einfaches Eintauchen in laues Wasser restlos vom Faden wieder entfernt werden kann.
Zur Förderung der Schlichtwirkung kön nen den Gelatine- und Alkoholgemischen selbstverständlich auch andere Stoffe, wie Benetzungsmittel (z. B. Natriumalkylnaph- thalinsulfonat), gärungsverhindernde Mittel (z. B. p-Ogybenzoesäuremethylester) oder . gelatinierverhindernde Mittel (z. B. Kali salpeter, Harnstoff), einzeln oder vereint, zugesetzt werden.
<I>Beispiel 1:</I> 6 kg tierische Gelatine 2 kg Harnstoff 0,05 kg Natriumalkylnaphthalinsulfonat 0,15 kg p-Oxybenzoesäuremethylester 7 kg denaturierten Alkohol 75 kg Wasser. Dieses Mittel kann wie folgt verwendet wer den: 10 kg Azetatseide in Strangform werden darin eingetragen und 1 Stunde bei einer Temperatur von 50 gelagert. Die so behan delte Kunstseide wird zentrifugiert und bei einer Höchsttemperatur von 70 getrocknet. Derart behandelte Fasern können nunmehr einer weiteren Verarbeitung unterzogen werden.
<I>Beispiel 2:</I> 6 kg tierische Gelatine 2 kg Kalisalpeter 5 kg Äthylenglykol 0,05 kg p-Oxybenzoesäuremethylsulfonat 7 kg Propylalkohol 75 kg Wasser.
Dieses Mittel wird in ähnlicher Weise wie im Beispiel 1 dargelegt gebraucht.
<I>Beispiel 3:</I> 2 kg Agar-Agar 0,5 kg Thioharnstoff 0,15 kg Natriumalkylnaphthalinsulfonat 7 kg Isopropylalkohol 75 kg Wasser.

Process for the production of a permanent agent used for the finishing of artificial textiles, in particular acetate silk. In the field of textiles, in particular artificial textiles, it is known to increase the resistance to manipulation in weaving and we kerei to provide the threads with a cover layer which sticks the individual fibers together and offers the thread mechanical protection.
This action is called sizing and, as is well known, not only has the task of the individual fibers forming the thread. to stick together, but also to protect the thread itself against the mechanical stresses to which it is exposed in the production process. The size must be sufficiently elastic to adapt to the deformation of the thread without tears, and it must be completely removable with simple means so that it cannot have any harmful influence on the subsequent dyeing and finishing of the fabric.
In order to achieve this goal, it is known that various polymeric or polymerizable substances, such as linseed oil, amides, animal and vegetable gelatine, or synthetic polymers are used.
In the special case of acetate silk, in which, in addition to a low water absorption capacity of the thread material, there is also a larger or smaller amount of blood necessary to combat static electricity, the size is preferred due to linseed oil dissolved in organic solvents or emulsified in water of aqueous adhesive solutions, generally introduced.
If the sizing of acetate silk is carried out on warp sizing machines, the textile material can also be glued with water-soluble substances, while water-soluble substances can generally not be used in strand sizing.
As a result of the low penetration capacity of the aqueous solutions into the interior of the thread, the threads themselves are glued to one another instead of the individual fibers forming the thread, making the winding of the strands onto the bobbins, which is necessary for further processing, extremely costly and difficult.
It has now been found that aqueous solutions of animal and vegetable colloids are perfectly suitable for sizing, even if they are strand-like acetate silk. a substance is added to these solutions which has the ability to carry the adhesive into the interior of the thread.
It has now been found that very satisfactory results are achieved if monohydric alcohols of the fatty series with a branched or unbranched chain and containing up to three carbon atoms are used as penetrants.
In this way, a perfect sizing of the individual fibers is accomplished without the individual threads sticking together, which are provided with a film-like, supple and mechanically resistant coating that protects the yarn against the stresses that occur during subsequent processing .
The subject of the patent is a process for the production of a permanent agent used to refine artificial textiles and especially acetate silk, characterized in that a monohydric alcohol of the fatty series with a maximum of three carbon atoms is incorporated into a solution of an organic colloid.
According to this process, a substantial economic and practical advantage is achieved, because the skin formed by the linseed oil can under certain circumstances cause various problems because the oxidation products of the linseed oil attach themselves very firmly to the thread, which, however, occurs when using animal products Charged is not the case, since the film can be completely removed from the thread by simply immersing it in lukewarm water.
To promote the sizing effect, the gelatine and alcohol mixtures can of course also contain other substances, such as wetting agents (e.g. sodium alkylnaphthalene sulfonate), fermentation-preventing agents (e.g. methyl p-ogybenzoate) or. Gelatinization-preventing agents (e.g. potash saltpeter, urea), individually or in combination, can be added.
Example 1: 6 kg of animal gelatin 2 kg of urea 0.05 kg of sodium alkylnaphthalene sulfonate 0.15 kg of methyl p-oxybenzoate 7 kg of denatured alcohol 75 kg of water. This agent can be used as follows: 10 kg of acetate silk in strand form are introduced into it and stored at a temperature of 50 for 1 hour. The rayon treated in this way is centrifuged and dried at a maximum temperature of 70. Fibers treated in this way can now be subjected to further processing.
<I> Example 2: </I> 6 kg of animal gelatin 2 kg of potassium nitrate 5 kg of ethylene glycol 0.05 kg of p-oxybenzoic acid methyl sulfonate 7 kg of propyl alcohol 75 kg of water.
This agent is used in a manner similar to that shown in Example 1
<I> Example 3: </I> 2 kg agar-agar 0.5 kg thiourea 0.15 kg sodium alkylnaphthalene sulfonate 7 kg isopropyl alcohol 75 kg water.
Usage similar to example 1.
