Description
Verfahren zum Trocknen von Kunstseide in Strahnform. Bei dem üblichen Verfahren zum Fertigmachen künstlicher Seide in Strahnfoim werden die Strähnen gewöhnlich zuerst in gestreckter Lage vorgetrocknet, dann chemisch behandelt und hierauf ein zweites Mal getrockiiet, indem tnan sie auf Stäbe hängt und der Einwirkung eines schwachen Heißluftstromes unterwirft. Die Fäden behalten bei Ausführung dieses Verfahrens eine gewisse Starrheit und Geschlossenheit, die sie :während des Trockners unter Zug beim ersten Trockenprozeß erla_-igt haben. Sie besitzen infolgedessen Eiur eriiige Deckkraft, die erheblich geringer ist als die Deckkraft natürlicher Seide. Method for drying rayon in the form of a stream. In the usual process of making artificial silk in strahnfoim, the strands are usually first pre-dried in a stretched position, then chemically treated and then dried a second time by hanging them on rods and subjecting them to the action of a weak stream of hot air. When this process is carried out, the threads retain a certain rigidity and cohesion, which they have allowed during the drying process under tension during the first drying process. As a result, they have extremely good coverage, which is considerably less than the coverage of natural silk.
Diesen Mängeln soll gemäß der Erfindung dadurch abgeholfen werden, dah die frisch gefällten Fäden, nachdem sie unter Spannung zunächst hinreichend vorgetrocknet worden sind, bei der Nachtrocknung so aufgehängt erden, daß sie eine begrenzte Bewegungsfreiheit haben und so der Einwirkung eines Heißluftstromes, von mindestens 3 bis 3 rn pro Sekunde unterworfen werden. Die Fäden ;,-erden 'fier durch aufgeschlossen, locker und weich. Die Mittel, durch welche die begrenzte Bew eglicbkeit der Strähnen erreicht wird, können verschiedene sein. So können beispielsweise die Strähnen lose von zwei Stangen A. B (Abb. z) getragen werden, die übereinander in geeigneter Entfernung voneinander in einem Luftkanal C angeordnet sind. Während sich die Strähnen in dieser Lage befinden, werden sie dem Heißluftstrom ausgesetzt.These deficiencies are to be remedied according to the invention, then the freshly felled threads, after they have initially been sufficiently pre-dried under tension, so hung up during post-drying that they have limited freedom of movement and so the action of a hot air stream, from at least 3 to 3 rn per second are subjected. The threads;, - ground 'fier through open-minded, loose and soft. The means by which the limited mobility of the strands is achieved can be various. For example, the strands can be carried loosely by two rods A. B (Fig. Z), which are arranged one above the other at a suitable distance from one another in an air duct C. While the strands are in this position, they are exposed to the stream of hot air.
Dasselbe Resultat wird erzielt, wenn man die Tragstangen AI, Bz für die Strähnen beispielsweise durch eine Kette E und Xettenräder F, F (Abb. 2) iz, Drehung versetzt. Die Stangen AI, BI können aber auch gegen Ende der Vortrockenperiode oder in irgendeinem andern Stadium des T,--ockn:rs aneinander gewöhnt und damit die Strähnen entspannt werden, z. B. wie in Abb. a veranschaulicht.The same result is achieved if the support rods AI, Bz for the strands, for example, by a chain E and Xettenräder F, F (Fig. 2) iz, Offset. The bars AI, BI can also be used towards the end of the pre-drying period or in some other stage of the T, - ockn: rs accustomed to each other and with it the strands are relaxed, e.g. B. as illustrated in Fig. A.
Derselbe Erfolg kann weiter auch erzielt werden, wenn man die Strähne D auf einem im Ouerschnitt kreisförmigen Strahnhalter 1C (Abb. 3) von etw: a iem (falben Umfange der Strähne aufhängt. Das untere herabhängende Ende der Strähne kann lose in seiner Lage durch eine Stange L von geeignetem Durchmesser gehalten werden, #ähr pnd die Strähne durch Drehung des Strahnhalters langsam gedreht und durch den Luftstrom bewegt wird# Der Luftstrom kann entweder von einem zentralen Rohr M geliefert werden, welches sich gerade unter dem Strahnhaspel befindet und auf die Innenseite der Strähne einwirken, oder er kann mittels eines Rohres Ml gegen die Außenseite der Strähne oder gegen beide Seiten gerichtet werden. Der Luftzug von außen kann auch durch einen Luftstrom in einer Leitung wie C (Abb. t) erzeugt werden.The same success can also be achieved by removing the streak D on a beam holder 1C of circular cross-section (Fig. 3) of something: a iem (The same circumference of the strand hangs up. The lower hanging end of the strand may be loosely held in place by a rod L of suitable diameter be, # ahr pnd the strand by turning the streamer slowly rotated and moved by the airflow # The airflow can either be from a central tube M are delivered, which is just under the jet reel and act on the inside of the strand, or it can by means of a tube Ml can be directed against the outside of the strand or against both sides. Of the A draft from the outside can also be caused by an air flow in a duct such as C (Fig. T) be generated.
Die Bewegung der Strähnen kann auch erzielt werden, z. B. durch Drehen des die lose aufgehängte Strähne tragenden Rahmens N um eine Welle 0 (Abb. q.), wobei die Linie, welche die beiden die Strähne tragenden Stangen P. P verbindet, vorteilhaft, wie veranschaulicht, geneigt zu einem Radius von der Achse der Welle 0 angeordnet wird.The movement of the strands can also be achieved, e.g. B. by turning of the frame N carrying the loosely suspended strand around a shaft 0 (Fig.q.), where the line connecting the two rods P. P supporting the strand, advantageously, as illustrated, inclined to a radius from the axis of the shaft 0 is arranged.
Eine Bewegung kann ferner erzielt werden, indem man die Strähne absatzweise, beispielsweise durch Rollen Q, Q (Abb. 5) unter Druck setzt und dabei eine oder beide Rollen hin und her dreht.Movement can also be achieved by intermittently applying pressure to the strand, for example by means of rollers Q, Q (Fig. 5), while rotating one or both rollers back and forth.
