Abstract
Description
Die Erfindung betrifft ein Transportband zum Transportieren eines pneumatisch zu verdichtenden Faserverbandes, welches wenigstens in einem den Faserverband führenden Bereich aus einem luftdurchlässigen Gewebe aus Kunststofffilamenten besteht, und wobei ein Teil der Kunststofffilamente mit einer elektrisch leitfähigen Oberfläche versehen ist.The The invention relates to a conveyor belt for transporting a pneumatic To be compressed fiber structure, which at least in one the fiber structure leading Area of an air-permeable Fabric consists of plastic filaments, and wherein a part of the Plastic filaments provided with an electrically conductive surface is.
Wenn einem verstreckten Faserverband auf einer Spinnmaschine in unmittelbarem Anschluss an das Ausgangswalzenpaar eines Streckwerks ein Spinndrall erteilt wird, dann entsteht an der Klemmlinie des Ausgangswalzenpaares ein so genanntes Spinndreieck. Dies rührt daher, dass der verstreckte Faserverband mit einer bestimmten Breite das Streckwerk verlässt und zu einem Faden relativ kleinen Durchmessers zusammengedreht wird. Das Spinndreieck enthält Randfasern, die nicht ordnungsgemäß in den verdrehten Faden eingebunden werden und somit wenig oder nichts zur Festigkeit des ersponnenen Fadens beitragen. Man ist daher in jüngerer Zeit dazu übergegangen, der Verzugszone des Streckwerks eine so genannte Verdichtungszone nachzuordnen, die ihrerseits von einer Klemmstelle auslaufseitig begrenzt wird. Erst danach wird dem Faden die Spinndrehung erteilt. In der Verdichtungszone werden die Fasern gebündelt oder verdichtet, wodurch der Faserverband beim Verlassen der letzten Klemmstelle so schmal wird, dass das gefürchtete Spinndreieck nicht mehr nachteilig ins Gewicht fällt. Der ersponnene Faden wird dann gleichmäßiger, fester und weniger haarig.If a stretched fiber strand on a spinning machine in immediate Connection to the pair of outfeed rollers of a drafting system, a spin twist is issued, then arises at the nip of the pair of output rollers a so-called spinning triangle. This is due to the fact that the stretched fiber structure with a certain width leaves the drafting and relative to a thread small diameter is twisted together. The spin triangle contains edge fibers, not properly in the twisted thread are involved and thus little or nothing contribute to the strength of the spun thread. One is therefore in younger Time has passed rearrange a so-called compaction zone of the drafting zone of the drafting system, which in turn is bounded on the outlet side by a clamping point. Only then is the thread given the spin rotation. In the compression zone the fibers are bundled or compacted, causing the fiber structure when leaving the last Nip so narrow that the dreaded spinning triangle is not more disadvantageous weight. The spun thread then becomes more uniform, firmer and less hairy.
Zum
Verdichten eines Faserverbandes sind recht unterschiedliche Vorrichtungen
bekannt geworden. Viele dieser Vorrichtungen arbeiten mit einem luftdurchlässigen Transportband,
welches den zu verdichtenden Faserverband gleitend über einen Saugschlitz
transportiert. Eine solche Vorrichtung ist beispielsweise in der
Es sei hier angemerkt, dass in der Terminologie dieser Patentanmeldung unter dem Begriff „pneumatisches Verdichten" auch solche Vorrichtungen inbegriffen sein sollen, bei denen außer dem Saugluftstrom auch andere Mittel, beispielsweise eine Transportkomponente gegen einen schief gestellten Saugschlitz, mitwirken können.It It should be noted here that in the terminology of this patent application under the term "pneumatic Compacting "too Such devices should be included, in which except the suction air flow Other means, for example, a transport component against a slanted suction slot, can participate.
Ein
Transportband der eingangs beschriebenen Art ist durch die
Eine Verschmutzung derartiger Transportbänder kann jedoch dadurch nicht vollständig verhindert werden, da die verarbeiteten Fasermaterialien teilweise auch stark haftende Verunreinigungen aufweisen, wie beispielsweise Wollfett oder Honigtau. Diese stark haftenden Verunreinigungen des Fasermaterials lagern sich mit der Zeit am Transportband an und verringern dadurch die Verdichtungswirkung der Vorrichtung, da die Luftdurchlässigkeit des Transportbandes nachlässt. Da dies ein schleichender Prozess ist, ist das besonders gefährlich weil ein Nachlassen der Verdichtungswirkung häufig erst spät bemerkt wird.A Pollution of such conveyor belts, however, can not Completely be prevented because the processed fiber materials partially also have strong adhesive impurities, such as Wool fat or honeydew. These strongly adhering impurities of the Fiber material accumulates over time on the conveyor belt and thereby reduce the compaction effect of the device, as the Air permeability of the conveyor belt decreases. Since this is a slow process, this is particularly dangerous because A decrease in the compression effect often noticed late becomes.
Der Erfindung liegt die Aufgabe zu Grunde, ein verbessertes Transportband für das pneumatische Verdichten eines Faserverbandes zu schaffen, welches eine verringerte Verschmutzungsneigung aufweist.Of the Invention is based on the object, an improved conveyor belt for the to create pneumatic compression of a fiber structure, which has a reduced tendency to fouling.
Die Aufgabe wird dadurch gelöst, dass ein anderer Teil der Kunststofffilamente eine fettabweisende Oberfläche aufweist.The Task is solved by that another part of the plastic filaments is a grease-repellent surface having.
Dadurch wird die Anlagerung von stark haftenden Verunreinigungen, welche sich durch eine verminderte elektrische Aufladung nicht beeinflussen lassen, reduziert. Die Luftdurchlässigkeit des Gewebes wird dadurch für einen wesentlich längeren Zeitraum aufrechterhalten.Thereby is the attachment of strongly adhering contaminants, which can not be influenced by a reduced electrical charge, reduced. The air permeability of the tissue is characterized for a much longer one Maintained period.
Die eine fettabweisende Oberfläche aufweisenden Kunststofffilamente lassen sich durch unterschiedliche Verfahren herstellen. Besonders vorteilhaft ist eine Beschichtung der Kunststofffilamente mit Polytetrafluorethylen (auch unter dem Markennamen Teflon bekannt) oder mit Stoffgemischen daraus. Die eine elektrisch leitfähige Oberfläche aufweisenden Kunststofffilamente sind vorteilhafter Weise als metallisierte Kunststofffilamente ausgebildet, bei denen die Kunststofffilamente mit einer metallischen Beschichtung versehen sind.The a grease repellent surface having plastic filaments can be distinguished by different Produce process. Particularly advantageous is a coating the plastic filaments with polytetrafluoroethylene (also under the Brand name Teflon) or with mixtures thereof. The one electrically conductive surface having plastic filaments are more advantageous than metallized Plastic filaments formed in which the plastic filaments provided with a metallic coating.
Vorzugsweise sind die eine fettabweisende Oberfläche aufweisenden Kunststofffilamente und die eine elektrisch leitfähige Oberfläche aufweisenden Kunststofffilamente im Wechsel angeordnet. Dadurch lassen sich die beiden Eigenschaften optimal vereinen. Es kann aber auch vorgesehen sein, die eine fettabweisende Oberfläche aufweisenden Kunststofffilamente vermehrt in dem den Faserverband führenden Bereich anzuordnen. Es wird dadurch insbesondere der Bereich vor stark haftenden Verunreinigungen geschützt, in dem die größten Mengen dieser Verunreinigungen auftreten. Diese stark haftenden Verunreinigungen werden nämlich hauptsächlich von dem zu verdichtenden Faserverband an das Transportband abgegeben.Preferably, the plastic filaments having a grease-repellent surface and the plastic filaments having an electrically conductive surface are arranged alternately. As a result, the two properties can be optimally combined. However, it may also be provided that the plastic filaments having a grease-repellent surface are increasingly arranged in the region leading the fiber structure. It is characterized in particular the area before strongly adhering Protected contaminants in which the largest amounts of these impurities occur. Namely, these strongly adhering impurities are mainly released from the fiber structure to be compacted to the conveyor belt.
Um eine ausreichende elektrostatische Ableitung des gesamten Transportbandes zu gewährleisten, kann es vorteilhaft sein, die eine elektrisch leitfähige Oberfläche aufweisenden Kunststofffilamente vermehrt neben dem den Faserverband führenden Bereich anzordnen.Around a sufficient electrostatic discharge of the entire conveyor belt to ensure, It may be advantageous to have an electrically conductive surface Plastic filaments increase next to the leading fiber structure Arrange area.
Besonders vorteilhaft ist das Transportband als endlos gewebtes Siebband ausgebildet.Especially Advantageously, the conveyor belt is designed as an endlessly woven screen belt.
