Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Befeuchten von Garn.The invention relates to a method and a device for moistening yarn.
Der Feuchtigkeitsgehalt von mindestens eine Woll- und/oder Baumwollkomponent enthaltendem. Garn beeinflußt verschiedene physikalische und chemische Eigenschaften des Garns, wie beispielsweise das elektrostatische Verhalten, das Faserflugverhalten oder das Ablaufverhalten über Kanten und Umlenkungen bei der Weiterverarbeitung insbesondere in Webereien und Stickereien oder dergleichen. The moisture content of at least one wool and / or cotton component containing. yarn affects various physical and chemical properties of the yarn, such as the electrostatic behavior, the fiber flight behavior or the flow behavior over edges and deflections during further processing especially in weaving and embroidery or the like.
Es hat sich gezeigt, daß für unterschiedliche Materialien unterschiedliche Feuchtigkeitsgehalte wünschenswert sind bzw. angestrebt werden, um besonders geeignete Eigenschaften für die Weiterverarbeitung zu schaffen. Dementsprechend wird Garn meist mit einem materialabhängigen Feuchtigkeitsgehalt bereitgestellt, der beispielsweise bei Baumwolle 8,5 Gewichtsprozent und bei Wolle 16,5 Gewichtsprozent beträgt und auch als Handelsfeuchte bezeichnet wird.It has been shown that different moisture contents for different materials are desirable or sought to be particularly suitable To create properties for further processing. Accordingly, will Yarn usually with a material-dependent moisture content provided, for example, in cotton 8.5 weight percent and in wool is 16.5 weight percent and also referred to as commercial moisture becomes.
Um diesen Feuchtigkeitsgehalt im Garn zu erreichen, ist vorgeschlagen worden, das Garn mit Dampf zu behandeln, um z. B. auch die durch den Spinnprozeß hervorgerufene sog. Kräuselneigung zu vermindern oder zu beseitigen.In order to achieve this moisture content in the yarn, it has been proposed to treat the yarn with steam, for. B. also by the spinning process reduce or eliminate the so-called curling tendency caused.
Bei einem bekannten Verfahren werden Woll- oder Baumwollfäden aufgespult und anschließend für mehrere Tage in einem Raum aufgehängt, der eine hohe Luftfeuchtigkeit aufweist.In a known method wool or cotton threads are wound up and then hung up for several days in a room that has a high Humidity has.
Die DE 38 28 630 A1 beschreibt diverse Nachteile dieses Verfahrens und schlägt vor, mehrere Kreuzspulen zu Säulen zu vereinigen und diese anschließend radial von innen nach außen zu durchdampfen. Hierzu werden perforierte Spulenhülsen in den Säuleninnenraum eingebracht, bevor Dampfdruck in den Hülseninnenraum geleitet wird. Bei diesem Verfahren wird die Feuchtigkeit in achsialer sowie in radialer Richtung der Spule dem Wickelgut ungleichmäßig zugeführt. Als Folge davon ist die Feuchtigkeit im Wickelgut inhomogen verteilt. Ferner besteht die Gefahr, daß sich Kondensat und damit lokale Übernässungen bilden.DE 38 28 630 A1 describes various disadvantages of this method and proposes To combine several cheeses to columns and then radial to penetrate from the inside to the outside. For this purpose, perforated bobbins placed in the column interior before vapor pressure in the sleeve interior is directed. In this process, the moisture in the axial and in Radial direction of the coil supplied to the winding material unevenly. As a result of which the moisture in the winding material is distributed inhomogeneous. Furthermore, there is the Danger that condensate and thus local overgrowths form.
Die DE 43 17 486 A1 beschreibt ein Verfahren, bei dem zu Kopsen gewickeltes Garn nach dem Spulprozeß in eine Dampfkammer eingebracht wird, in der diese Kopse bedampft und zusätzlich mit einem Fluid erwärmt werden, um die Kondensatbildung zu vermindern. Dieses Verfahren erfordert, gemessen an den erzielbaren Ergebnissen, einen hohen Steuerungs- und Regelaufwand. Die Kondensatbildung und lokale Übemässungen lassen sich aber nur unzureichend vermindern. Das Verfahren erfordert ferner hohe Durchlauf- und Umrüstzeiten. Ungünstig kann es sich auch auswirken, daß der Feuchtigkeitsgehalt innerhalb der Dampfkammer in aller Regel von dem Feuchtigkeitsgehalt außerhalb der Dampfkammer abweicht. Beim Einführen oder Entnehmen von Kopsen in die bzw. aus der Dampfkammer findet ein Feuchtigkeitsaustausch zwischen dem Kammerinnem und der Umgebung zumindest dann statt, wenn die Kammertore geöffnet sind. Dieser Effekt wird nur unzureichend berücksichtigt. Ferner ist auch nicht eine homogene Verteilung der Feuchtigkeit im Wikkelgut gewährleistet.DE 43 17 486 A1 describes a method in which wound to cops Yarn is introduced after the winding process in a steam chamber in which this Cops steamed and additionally heated with a fluid to the condensation to diminish. This method requires, measured by the achievable Results, a high level of control and regulation. The condensation and local measures can only be reduced insufficiently. The method also requires high throughput and changeover times. Unfavorable It may also affect the moisture content within the steam chamber usually from the moisture content outside the steam chamber differs. When inserting or removing cops in or out of the Steam chamber finds a moisture exchange between the Kammerinnem and the environment at least when the chamber doors are open. This effect is considered insufficient. Furthermore, not one ensures homogeneous distribution of moisture in Wikkelgut.
In der DE-PS 25 13 306 ist eine Vorrichtung an Zwirn- oder Spulmaschinen zum Avivieren der Fäden auf ihrem Weg von der Lieferspule zur Aufwickelspule beschrieben. Diese Vorrichtung hat ein der Aufwickelspule vorgelagertes, sich längs der Maschine erstreckendes Speicherrohr für Avivage. Das Speicherrohr ist im Bereich jedes Aufwickelaggregates mit einem porösen Körper mit Kapillarwirkung versehen, der in die im Speicherraum befindliche Avivageflüssigkeit eintauchende Ansätze aufweist, und an dem der aufzuwickelnde Faden im Bereich des sog. Changierdreiecks entlangstreift, wodurch Avivage an den über den porösen Körper streifenden Faden abgegeben wird.In DE-PS 25 13 306 is a device on twisting or winding machines for Avivieren the threads described on their way from the supply spool to the take-up reel. This device has one of the take-up reel upstream, along the machine extending storage tube for lubrication. The storage tube is in Area of each Aufwickelaggregates with a porous body with capillary action provided immersed in the in the storage space Avivageflüssigkeit Has lugs, and on which the wound thread in the region of so-called Changierdreiecks along, thereby Avivage to the over the porous Body grazing thread is dispensed.
Die US-A-3,281,223 beschreibt die Feuchtigkeitsbehandlung von Endlosfilamenten aus einem bei Wärme schmelzenden Mineralmaterial, zum Beispiel Glasfaserfilamenten, die mit einer Beschichtung versehen sind, die insbesondere im Bereich der konischen Endabschnitte einer Spule, auf die beim Spulenaufbau keine weiteren Filamentlagen aufgewickelt werden, die Tendenz zum Trocknen oder schnellen Aushärten und damit Verkleben haben. Dieses Verfahren vermittelt keine Lehre, die für das Konditionieren von eine Woll- und/oder Baumwollkomponente enthaltendem Garn geeignet ist, um über die gesamte, auf die Spule aufgewickelte Garnlänge einen geeigneten Feuchtigkeitszustand zu erhalten.US-A-3,281,223 describes the moisture treatment of continuous filaments from a heat-melting mineral material, for example glass-fiber filaments, containing a coating are provided, in particular in the region of the conical end portions a coil on the coil assembly wound up no more filament layers be the tendency to dry or fast curing and thus sticking to have. This method does not teach you how to condition a Wool and / or cotton component containing yarn is suitable to over the entire, on the spool wound yarn length to a suitable moisture state receive.
