Description
Vorrichtung zur Aufarbeitung von verstreckten Fäden aus hochmolekularen aromatischen Polyestern Die Aufarbeitung von Fäden aus hochmolekula ren aromatischen Polyestern erfolgte bisher in dis kontinuierlicher Weise, wobei die verstreckten Fäden zunächst gezwirnt und auf Spulen aufgewickelt wur den, deren Kern aus einem nachgiebigen Drahtgefüge besteht. Auf diesen Spulen wurden die Fäden bisher einer längeren Dampfbehandlung ausgesetzt, wobei die auf der Spule befindlichen Polyesterfäden schrumpfen konnten und gleichzeitig fixiert wurden.
Nach diesem Thermofixierungsprozess wurden die Fäden auf neue verkaufsfähige Spulen aufgewickelt.
Gegenstand der vorliegenden Erfindung ist eine Vorrichtung, mit Hilfe deren der gesamte Arbeitspro- zess, d. h. die Aufarbeitung von verstreckten Fäden bis zur verkaufsfertigen Form, kontinuierlich in einem Arbeitsgang durchgeführt werden kann.
Ge genstand der Erfindung ist eine Vorrichtung zur Auf arbeitung von verstreckten Fäden aus hochmolekula ren aromatischen Polyestern, welche gekennzeichnet ist durch eine sich schnell drehende Spindel, einen Fadenführer, eine Umlenkrolle, einen Behälter, eine heizbare Galette mit Verlegewalze, einen Heizkasten, eine Abzugsgalette mit Verlegewalze, eine Streckga- lette mit Verlegewalze,
eine Umlenkrolle und eine Aufwickelspule mit Changierung.
Die Fäden werden zweckmässig in einem konti nuierlichen Prozess zunächst gezwirnt, dann durch eine Lösung, Dispersion oder Emulsion eines oder mehrerer Stoffe geleitet, die zwischen 120 und 350 C sieden, hierauf werden die Fäden vorzugs weise über zwei als Fixpunkte dienende, verschieden schnell angetriebene Galetten, die von dem Faden mehrmals umschlungen werden und von denen die erste Galette geheizt ist, weitergeleitet und zwischen diesen Galetten allseitig gleichmässig auf eine Tem peratur zwischen 220 und 350 C, vorzugsweise zwi schen 250 und 280 C, während einer Zeit von 0,
1 bis 5 Sekunden, vorzugsweise 0,2 bis 1 Sekunde, er hitzt und gleichzeitig um einen einstellbaren Betrag von 5 bis 35 %, vorzugsweise 10 bis 25 %, ge- schrumpft. Daraufhin können die Fäden um densel ben oder um einen grösseren Betrag oder um einen kleineren Betrag erneut verstreckt und anschliessend aufgespult werden.
Im allgemeinen wird das Nach- verstrecken zweckmässig so durchgeführt, dass die fertigen Fäden den für ihre weitere Verarbeitung in der Weberei und in der Wirkerei günstigsten Koch- oder Thermoschrumpf besitzen, so dass sich eine Fixierung der so hergestellten Fäden erübrigt. Unter dem Ausdruck Kochschrumpf wird der Schrumpf betrag, ausgedrückt in Prozenten, verstanden, den ein Faden beim Eintauchen in kochendes Wasser erhält.
Unter dem Ausdruck Thermoschrumpf soll ver standen werden der Schrumpfbetrag eines Fadens nach dem Einbringen in 200 C heisse Luft bei einer Zeitdauer von wenigen Sekunden. Sofern die Fäden um denselben oder um einen höheren Betrag nach- verstreckt werden, ist es zweckmässig, die nachver- streckten Fäden noch mit Hilfe von Wasserdampf oder von trockener heisser Luft zu behandeln.
Drei beispielsweise Ausführungsformen der erfin dungsgemässen Vorrichtung sind in der Zeichnung dargestellt.
Bei der in Fig. 1 dargestellten Vorrichtung wer den die verstreckten Fäden aus linearen aromati schen Polyestern zunächst auf einen Kops aufgewik- kelt, anschliessend wird dieser Kops auf eine sich schnell drehende Spindel 1 aufgesteckt und der Faden nach oben abgezogen.
Bei diesem Prozess wird der Faden gezwirnt, anschliessend läuft er über einen Fadenführer 2, eine Umlenkrolle 3, worauf er durch eine Behandlungsflüssigkeit, die sich in einem Behäl ter 4 befindet, geführt wird; anschliessend wird der Faden an der geheizten Galette 5 getrocknet und durch den Heizkasten 7, dessen Temperatur 220 bis 350 C beträgt, geleitet.
Zwischen den als Fixpunkte dienenden Galetten 5 und 8, die von dem Faden mehrmals umlaufen werden, kann der Faden um einen Betrag zwischen 5 und 35 % schrumpfen. Daraufhin läuft der Faden zu einer weiteren Galette 10, die eine höhere Geschwindigkeit hat als die Galette 8,
so dass der Faden zwischen Galette 8 und Galette 10 um 5 bis 35 % verstreckt wird. Anschlies- send wird der Faden auf die Spule 14 aufgewickelt.
Eine weitere Ausführungsform der erfindungsge- mässen Vorrichtung ist in Figur 2 erläutert: Der Faden wird ebenso wie bei Figur 1 gezwirnt und durch die Behandlungsflüssigkeit geführt. An schliessend wird er auf der geheizten Galette 5 ge trocknet, durchläuft anschliessend den Heizkanal 7 (Temperatur 220 bis 350 C) und gelangt dann auf die langsamer laufende Galette B. Zwischen Galette 5 und Galette 8 kann der Faden um jeden gewünschten Betrag schrumpfen.
Daraufhin wird der Faden auf eine dritte Galette 10 geleitet, die als Stufengalette auf die Galette 5 aufgesetzt ist. Die Stufengalette 10 läuft schneller als die Galette 8, so dass der Faden zwischen der Galette 8 und der Stufengalette ver- streckt wird, und zwar in einem kleineren Ausmass als er vorher schrumpfen konnte.
Nach dem Ver- strecken wird der Faden über die Umlenkrolle 12 und die Changierung 13 auf die Spule 14 aufgewik- kelt. Die Temperatur der Trockengalette 5 beträgt zweckmässig 50 bis 120 C.
Der Faden wird wie bereits erwähnt durch eine Lösung, Dispersion oder Emulsion mindestens eines Stoffes geleitet, der zwischen 120 und 350 C siedet und der sich entweder später durch Waschen wieder entfernen lässt oder der den Charakter einer Präpa- ration besitzt und infolgedessen nicht stört, wenn er auf dem Faden verbleibt. Die chemische Natur dieses Stoffes spielt nur eine untergeordnete Rolle. Aus schlaggebend sind seine physikalischen Eigenschaf ten, und aus diesem Grunde sind zur Durchführung des Verfahrens Verbindungen der verschiedensten Stoffklassen geeignet. Wichtig ist, dass die Stoffe zwi schen 120 und 350 C sieden.
Bei einem Zusatz von Farbstoffen zu der Be handlungsflüssigkeit erhält man ferner gleichzeitig gefärbte Fäden, oder es wird bei Mitverwendung optischer Aufheller, z. B. einem Stoff der Formel
EMI0002.0066
eine Verbesserung des Weissgrades der Fäden erzielt. Ausserdem ist es möglich, auf den Faden Schlichtemittel aufzubringen, wenn das Behandlungs bad Schlichtemittel enthält. So werden z. B. mit Emulsionen von sauren Polyacrylsäureestern hervor ragend geschlichtete Fäden erhalten.
Wenn man eine besonders gute Anfärbbarkeit der Fäden erzielen will und gleichzeitig ihren Griff und ihren Glanz günstig beeinflussen möchte, ist es zweckmässig, statt Fäden mit rundem Querschnitt, solche mit einem Querschnittprofil zu verwenden, die eine grössere Faseroberfläche aufweisen. In Frage kommen Dreiecks-, Stern-, Hantel- oder andere Pro file. Diese Fäden nehmen unter denselben Behand lungsbedingungen mehr Farbstoff auf als Fäden mit rundem Querschnitt, so dass es möglich ist, auch sehr dunkle Färbungen ohne Mitverwendung von Carriern zu erhalten.
In besonderen Fällen kann es auch vorteilhaft sein, mit Fäden aus Polyäthylenterephthalat von niedrigerer Viskosität, z. B. von der spezifischen Vis kosität 0,450 bis 0,700 zu arbeiten. Mit spezifischer Viskosität ist diejenige Viskosität gemeint, die man mit einer 1 ohigen Lösung der Polyester in einem Lösungsmittelgemisch aus 60 Teilen Phenol und 40 Teilen Tetrachloräthan bei 25 C bestimmt.
Diese Fäden lassen sich unter milderen Behandlungsbedin gungen, d. h. bei niedrigeren Temperaturen und ge ringerem Schrumpf, bereits um denselben oder um einen höheren Prozentsatz in ihrer Farbstoffaufnah- mefähigkeit verbessern als Fäden aus Polyäthylente- rephthalat der spezifischen Viskosität 0,800.
Durch die beiliegende Figur 3 wird eine weitere Ausführungsform der erfindungsgemässen Vorrich tung erläutert. Ein verstreckter Polyesterfaden wird mit Hilfe einer Zwirnspindel 1 gezwirnt, durchläuft dann anschliessend den Fadenführer 2 und das Be handlungsbad 4, das mit einer Lösung, einer Disper sion oder einer Emulsion der eingangs beschriebenen Stoffe beschickt ist. Der Faden wird mit diesen Stof fen getränkt und anschliessend auf der geheizten Galette 5 getrocknet. Er durchläuft den Heizkasten 7, in welchem: er um 5 bis 35 /o schrumpfen kann, weil die Galette 8 um diesen Betrag langsamer läuft als die Galette 5.
Daraufhin wird der Faden auf eine heizbare Galette 10 geleitet, die als Stufengalette auf die Galette 5 aufgesetzt ist. Diese Stufengalette kann einen ebenso grösseren oder kleineren Durchmesser wie die Galette 5 haben. Sie läuft schneller als die Galette 8, so dass der Faden zwischen Galette 8 und Galette 10 um einen einstellbaren Betrag verstreckt wird. Nach dem Verstrecken wird der Faden erneut durch einen Heizkanal 12 geleitet, der auf 220 bis 350 C geheizt ist.
Er gelangt dann über die Umlenk- rolle 13 und die Changierung 14 zur Aufspulrolle 15, die eine geringere Umfangsgeschwindigkeit auf weist als die Galette 10, so dass der Faden auf der Strecke zwischen der Galette 10 und der Aufspulung 15 im Heizkanal 12 um einen einstellbaren Betrag erneut schrumpfen kann. Führt man beide Schrumpf vorgänge bei derselben Temperatur durch, so kann anstelle der beiden Heizkästen 7 und 12 auch nur ein Heizkasten Verwendung finden, den dann der Faden zweimal durchläuft.
Die mit der erfindungsgemässen Vorrichtung her gestellten Fäden sind veredelt und lassen sich mit Dispersionsfarbstoffen besonders gut anfärben. Aus- serdem besitzen die behandelten Fäden gute textile Eigenschaften. So können z. B. ihre Schrumpfwerte je nach dem. Grade der Wiederverstreckung beliebig eingestellt werden. Die für viele Zwecke bei der wei teren Verarbeitung unerwünschte hohe Dehnung wird durch das erneute Verstrecken geringer.
Apparatus for processing stretched threads from high molecular weight aromatic polyesters The processing of threads made from hochmolecular aromatic polyesters has so far been carried out in a continuous manner, the stretched threads initially being twisted and wound onto bobbins whose core consists of a flexible wire structure. The threads on these bobbins were previously subjected to a longer steam treatment, whereby the polyester threads on the bobbin could shrink and were fixed at the same time.
After this heat setting process, the threads were wound onto new salable spools.
The subject of the present invention is a device with the aid of which the entire work process, d. H. the processing of drawn threads up to the ready-to-sell form can be carried out continuously in one operation.
The subject of the invention is a device for processing drawn threads made of hochmolekula Ren aromatic polyesters, which is characterized by a rapidly rotating spindle, a thread guide, a pulley, a container, a heatable godet with laying roller, a heating box, a godet with Laying roller, a stretching pallet with laying roller,
a pulley and a take-up reel with traversing.
The threads are expediently first twisted in a continuous process, then passed through a solution, dispersion or emulsion of one or more substances that boil between 120 and 350 C, then the threads are preferably driven via two godets that serve as fixed points and are driven at different speeds , which are looped around several times by the thread and of which the first godet is heated, forwarded and between these godets evenly on all sides to a temperature between 220 and 350 C, preferably between 250 and 280 C, for a time of 0,
1 to 5 seconds, preferably 0.2 to 1 second, it heats and at the same time shrinks by an adjustable amount of 5 to 35%, preferably 10 to 25%. The threads can then be stretched again by the same amount or by a larger amount or by a smaller amount and then wound up.
In general, post-stretching is expediently carried out in such a way that the finished threads have the most favorable boiling or thermal shrinkage for their further processing in weaving and knitting, so that there is no need to fix the threads produced in this way. The expression boiling shrinkage is understood to mean the amount of shrinkage, expressed as a percentage, that a thread receives when immersed in boiling water.
The term thermal shrinkage should be understood to mean the amount of shrinkage of a thread after it has been placed in hot air at 200 C for a period of a few seconds. If the threads are re-drawn by the same or a higher amount, it is expedient to treat the re-drawn threads with the aid of steam or dry, hot air.
Three exemplary embodiments of the device according to the invention are shown in the drawing.
In the device shown in FIG. 1, the drawn threads made of linear aromatic polyesters are first wound onto a cop, then this cop is attached to a rapidly rotating spindle 1 and the thread is pulled off upwards.
In this process, the thread is twisted, then it runs over a thread guide 2, a pulley 3, whereupon it is guided through a treatment liquid that is in a Behäl ter 4; the thread is then dried on the heated godet 5 and passed through the heating box 7, the temperature of which is 220 to 350.degree.
The thread can shrink by an amount between 5 and 35% between the godets 5 and 8, which are used as fixed points and which are rotated several times by the thread. The thread then runs to a further godet 10, which has a higher speed than the godet 8,
so that the thread between godet 8 and godet 10 is stretched by 5 to 35%. The thread is then wound onto the bobbin 14.
A further embodiment of the device according to the invention is explained in FIG. 2: the thread is twisted as in FIG. 1 and passed through the treatment liquid. Then it is dried on the heated godet 5, then passes through the heating channel 7 (temperature 220 to 350 C) and then reaches the slower running godet B. Between godet 5 and godet 8, the thread can shrink by any desired amount.
The thread is then directed to a third godet 10, which is placed on the godet 5 as a step godet. The step godet 10 runs faster than the godet 8, so that the thread is stretched between the godet 8 and the step godet, to a smaller extent than it was previously able to shrink.
After stretching, the thread is wound onto the bobbin 14 via the deflecting roller 12 and the traversing mechanism 13. The temperature of the drying godet 5 is expediently 50 to 120 C.
As already mentioned, the thread is passed through a solution, dispersion or emulsion of at least one substance which boils between 120 and 350 C and which can either be removed later by washing or which has the character of a preparation and therefore does not interfere if it remains on the thread. The chemical nature of this substance only plays a subordinate role. Its physical properties are decisive, and for this reason compounds of the most varied classes of substances are suitable for carrying out the process. It is important that the substances boil between 120 and 350 C.
When dyes are added to the treatment liquid, colored threads are also obtained at the same time, or when optical brighteners are used, e.g. B. a substance of the formula
EMI0002.0066
an improvement in the whiteness of the threads is achieved. It is also possible to apply sizing agents to the thread if the treatment bath contains sizing agents. So z. B. obtained excellent sized threads with emulsions of acidic polyacrylic acid esters.
If you want to achieve a particularly good dyeability of the threads and at the same time want to influence their feel and their gloss favorably, it is advisable to use threads with a cross-sectional profile that have a larger fiber surface instead of threads with a round cross-section. Triangle, star, dumbbell or other profiles are possible. Under the same treatment conditions, these threads absorb more dye than threads with a round cross-section, so that it is possible to obtain even very dark colors without using carriers.
In special cases, it may also be advantageous to use threads made of polyethylene terephthalate of lower viscosity, e.g. B. to work from the specific Vis viscosity 0.450 to 0.700. Specific viscosity means that viscosity which is determined at 25 ° C. with a 1 oh solution of the polyester in a solvent mixture of 60 parts of phenol and 40 parts of tetrachloroethane.
These threads can be used under milder treatment conditions; H. at lower temperatures and less shrinkage, their dye absorption capacity is already improved by the same or a higher percentage than threads made of polyethylene terephthalate with a specific viscosity of 0.800.
The enclosed FIG. 3 explains a further embodiment of the device according to the invention. A drawn polyester thread is twisted using a twisting spindle 1, then passes through the thread guide 2 and the treatment bath 4, which is charged with a solution, a dispersion or an emulsion of the substances described above. The thread is soaked in these fabrics and then dried on the heated godet 5. It runs through the heating box 7, in which: it can shrink by 5 to 35 / o because the godet 8 runs slower than the godet 5 by this amount.
The thread is then directed to a heatable godet 10, which is placed on the godet 5 as a step godet. This step godet can have a larger or smaller diameter than the godet 5. It runs faster than the godet 8, so that the thread between godet 8 and godet 10 is stretched by an adjustable amount. After drawing, the thread is again passed through a heating channel 12 which is heated to 220 to 350.degree.
It then arrives via the deflecting roller 13 and the traversing 14 to the winding roller 15, which has a lower peripheral speed than the godet 10, so that the thread on the path between the godet 10 and the winding 15 in the heating channel 12 by an adjustable amount can shrink again. If both shrinking processes are carried out at the same temperature, only one heating box can be used instead of the two heating boxes 7 and 12, through which the thread then passes twice.
The threads produced with the device according to the invention are refined and can be dyed particularly well with disperse dyes. In addition, the treated threads have good textile properties. So z. B. their shrinkage values depending on the. Degree of re-stretching can be set arbitrarily. The high elongation, which is undesirable for many purposes in further processing, is reduced by the renewed stretching.
