Abstract

In this method, a disordered staple fibre material is rendered uniform and parallel in order to produce representative textile fibre samples. For this purpose, a piece of the original fibre material (6) to be analysed is brought between two parallel plates (1, 2), which are arranged at a constant distance from one another and have oppositely acting needles with a saw-tooth profile (3, 4) which engage in the fibre material (6). The two plates (1, 2) are now moved relative to one another while maintaining the mutual distance, and this brings about a linear separation of the fibre material (6) into its individual fibres. It is then possible to use a sample clamp (5) to extract from the parallel fleece thus produced a random, orthogonal cross-sectional sample (11) whose composition corresponds largely to the original fibre material (6), and which is therefore suitable for carrying out the most varied quality tests. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von repräsentativen, textilen Faserproben, sowie einer Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for producing representative, textile fiber samples, and an apparatus for performing the method.

Bei den heute bekannten Verfahren zur Vergleichmässigung und Parallelisation von Stapelfasermaterial in der Textilindustrie werden regelmässig die langen Fasern bevorzugt, so dass die zubereitete Faserprobe gegenüber dem Originalprodukt einen künstlich erhöhten Anteil an langen Fasern enthält und so die mit der Faserprobe durchzuführenden Messungen und Untersuchungen verfälscht.In the processes known today for the uniformization and parallelization of staple fiber material in the textile industry, the long fibers are regularly preferred, so that the prepared fiber sample contains an artificially increased proportion of long fibers compared to the original product and thus falsifies the measurements and examinations to be carried out with the fiber sample.

Repräsentativ für den heute bekannten Stand der Technik ist beispielsweise die Apparatur gemäss der CH-A-488 187, bei der das Fasermaterial mittels eines Rechens einer perforierten Trom­melvorrichtung entnommen wird. Diese Technik der Probeentnahme führt wegen der besseren Erfassungswahrscheinlichkeit der längeren Fasern zu einer Anreicherung solcher Fasern in der entnommenen Faserprobe, so dass ein längenbetontes Fasermuster erhalten wird.Representative of the prior art known today is, for example, the apparatus according to CH-A-488 187, in which the fiber material is removed from a perforated drum device by means of a rake. Because of the better detection probability of the longer fibers, this technique of sampling leads to an accumulation of such fibers in the fiber sample taken, so that a length-emphasized fiber pattern is obtained.

Auch beim bekannten Verfahren gemäss der CH-A-637 468, bei dem eine Messung der Längenverteilung von Textilfasern durch Auflösung eines Faservlieses im Luftstrom, Fixierung der Einzelfasern auf eine umlaufende Siebtrommel und anschliessende optische Bestimmung der Faserlängen erfolgt, erhält man eine Verfälschung des Messresultats, weil die Verstreckung der Fasern in der Praxis dazu führt, dass sich diese um die Walzen herum aufwickeln. Es ist somit ausgeschlossen ein repräsentatives Muster zu erhalten. Auch das Absaugen auf der Trommel führt zu einer weiteren Verfälschung des Ergebnisses) weil kleinere Fasern in das Innere der Siebtrommel gesaugt werden.Even with the known method according to CH-A-637 468, in which the length distribution of textile fibers is measured by dissolving a nonwoven fabric in an air stream, fixing the individual fibers to a rotating sieve drum and then optically determining the fiber lengths, the measurement result is falsified, because in practice stretching the fibers causes them to wind around the rollers. It is therefore impossible to obtain a representative sample. Suctioning on the drum also leads to a further falsification of the result) because smaller fibers are sucked into the inside of the sieve drum.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zugrunde, auf einfache und zuverlässige Weise ein weitgehend unbetontes Fasermuster zu gewinnen.The invention seeks to remedy this. The object of the invention is to obtain a largely unstressed fiber pattern in a simple and reliable manner.

Die Erfindung löst die gestellte Aufgabe mit einem Verfahren, welches die Merkmale des Anspruchs 1 aufweist, sowie einer Vorrichtung zur Durchführung des Verfahrens, welche die Merkmale des Anspruchs 8 aufweist.The invention achieves the stated object with a method which has the features of claim 1 and an apparatus for carrying out the method which has the features of claim 8.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass dank des erfindungsgemässen Verfahrens eine repräsentative Menge Stapelfasermaterial ohne Verluste in ein unbetontes Labormuster zerlegt werden kann.The advantages achieved by the invention can essentially be seen in the fact that, thanks to the method according to the invention, a representative quantity of staple fiber material can be broken down into an unstressed laboratory pattern without losses.

In den Figuren ist eine Vorrichtung zur Vergleichmässigung und Parallelisation von Stapelfasermaterial zur erfindungsgemässen Herstellung von repräsentativen, textilen Faserproben dargestellt, welche in ihrem grundsätzlichen Aufbau aus zwei, miteinander in Eingriff bringbaren Tellern 1 und 2 mit entsprechenden Garnituren oder Nadeln 3 und 4 besteht, deren relativer Abstand zueinander stufenlos einstellbar ist. Der Abstand zwischen den beiden Tellern 1 und 2 wird im Bereich zwischen 0 bis 10 mm rohstoffspezifisch optimiert.The figures show a device for the equalization and parallelization of staple fiber material for the production of representative textile fiber samples according to the invention, which in its basic structure consists of two plates 1 and 2 which can be brought into engagement with one another corresponding sets or needles 3 and 4, the relative distance between which is infinitely adjustable. The distance between the two plates 1 and 2 is optimized in the range between 0 and 10 mm depending on the raw material.

Bei der in Fig. 1 dargestellten bevorzugten Ausführung sind die Teller 1 und 2 von kreisförmiger Gestalt. Ganz allgemein können aber auch andere geometrische Formen verwendet werden, beispielsweise zwei zueinander parallele Zylindermantelflächen.In the preferred embodiment shown in Fig. 1, the plates 1 and 2 are circular in shape. In general, however, other geometric shapes can also be used, for example two mutually parallel cylindrical jacket surfaces.

Die Garnituren 3 und 4 der beiden Teller 1 und 2 bestehen aus Häkchen auf dem einen Teller 1 und aus mit den Häkchen zusammenwirkenden Gegenhäkchen auf dem anderen Teller 2. Vorzugsweise weisen die beiden Garnituren 3 und 4, wie in Fig. 2 dargestellt, ein sägezahnförmiges Profil auf. Es sind aber auch Kombinationen mit unterschiedlichen Garniturstrukturen möglich, beispielsweise ein Sägezahnprofil auf dem oberen Teller 2 und Häkchen auf dem unteren Teller 1 oder umgekehrt.The sets 3 and 4 of the two plates 1 and 2 consist of hooks on one plate 1 and counter hooks interacting with the hooks on the other plate 2. Preferably, the two sets 3 and 4, as shown in FIG. 2, have a sawtooth shape Profile on. However, combinations with different clothing structures are also possible, for example a sawtooth profile on the upper plate 2 and ticks on the lower plate 1 or vice versa.

Der obere der beiden Teller 2 weist bei der in Fig. 1 dar­gestellten bevorzugten Ausführungsform eine Einspeisevorrichtung 7 für das Fasermaterial 6 auf, welche im wesentlichen aus einem parallelen zusammenwirkenden Walzenpaar besteht.In the preferred embodiment shown in FIG. 1, the upper one of the two plates 2 has a feed device 7 for the fiber material 6, which essentially consists of a parallel, cooperating pair of rollers.

Der untere der beiden Teller 1 weist einen Musterentnahmeschlitz 8 auf, in welchen eine Musterklemme 5 eingeführt werden kann, welche im wesentlichen aus zwei mittels eines Scharniers 12 drehbar miteinander verbundenen Kämmen 13 und 14 und einer Verriegelung 15 besteht, mit welcher die freien Enden der Kämme 13 und 14 fixiert werden können.The lower of the two plates 1 has a sample removal slot 8, into which a sample clamp 5 can be inserted, which essentially consists of two by means of a hinge 12 Combs 13 and 14 rotatably connected to one another and a lock 15 with which the free ends of the combs 13 and 14 can be fixed.

Die beiden Teller 1 und 2 weisen je eine Achse 16 und 17 auf, mit der eine manuelle oder maschinelle Rotation erzeugt werden kann.The two plates 1 and 2 each have an axis 16 and 17, with which a manual or mechanical rotation can be generated.

Das erfindungsgemässe Verfahren wird nun anhand der einzelnen, verschiedene Arbeitsphasen darstellende Figuren im einzelnen erläutert.The method according to the invention will now be explained in detail on the basis of the individual figures representing different working phases.

Wie in den Fig. 1 und 2 dargestellt, werden die beiden Teller 1 und 2 durch Gegeneinanderfahren längs der Achsen 16 und 17 in die Arbeitsstellung gebracht, wobei der Abstand zwischen den beiden Tellern 1 und 2 je nach Materialmenge und Materialbeschaffenheit differenziert einstellbar ist. Das Fasermaterial 6 wird nun über die Einspeisevorrichtung 7 zwischen die relativ zueinander entgegengesetzt rotierenden, mit je einer Garnitur 3 und 4 bestückten Teller 1 und 2 ge­bracht.As shown in FIGS. 1 and 2, the two plates 1 and 2 are brought into the working position by moving against one another along the axes 16 and 17, the distance between the two plates 1 and 2 being adjustable depending on the amount of material and the nature of the material. The fiber material 6 is now brought via the feed device 7 between the plates 1 and 2, which rotate in opposite directions relative to one another and are each equipped with a clothing 3 and 4.

Durch die relativ gegeneinander stattfindende Rotationsbewegung der Teller 1 und 2, übt die eine der beiden Garnituren 3 auf das Fasermaterial 6 eine Rückhaltekraft und die andere Garnitur 4 die Ausziehkraft aus, wobei entweder der untere Teller 1 zum oberen Teller 2 (oder umgekehrt) relativ langsamer laufen kann.Due to the relative rotational movement of the plates 1 and 2, one of the two sets 3 exerts a retaining force on the fiber material 6 and the other set 4 exerts the pulling force, either the lower plate 1 to the upper plate 2 (or vice versa) relatively slowly can run.

Bei diesem in Fig. 2 dargestellten Vorgang, entsteht aus dem originalen Faservlies 6, ein Fasermuster mit radialen und zueinander weitgehend parallelen Faserachsen.In this process shown in FIG. 2, the original fiber fleece 6 is used to produce a fiber pattern with radial and largely parallel fiber axes.

In Fig. 3 ist die Phase der Musterentnahme dargestellt, welche mit Hilfe der in Fig. 4 dargestellten Musterklemme 5 stattfindet. Die Musterklemme 5 wird nach Stillsetzung der Teller 1 und 2 mit geöffneten Kämmen 13 und 14 in den Musterentnahmeschlitz 8 eingeführt und mittels der Verriegelung 15 verriegelt, dabei wird der Musterbart 11 in der Musterklemme 5 rutschfest fixiert. Nun werden die Teller 1 und 2 auseinandergefahren und der Musterbart 11 kann zusammen mit der Musterklemme 5 entnommen werden.FIG. 3 shows the phase of the sampling, which takes place with the aid of the sample clamp 5 shown in FIG. 4. After the plates 1 and 2 have been shut down, the sample clamp 5 is inserted into the sample removal slot 8 with open combs 13 and 14 and locked by means of the lock 15, the sample bit 11 being fixed non-slip in the sample clamp 5. Now the plates 1 and 2 are moved apart and the sample bit 11 can be removed together with the sample clamp 5.

Das Fasermuster oder besser der Fasermusterbart 11 wird nun in den meisten Fällen noch von den ungeklemmten Fasern durch geeig­nete Bürstoperationen befreit. Ein so vorbereiteter Fasermuster­bart 11 kann als Prüfling für verschiedene Bestimmungen, wie Fa­serlänge, Faserreife, Faserfeinheit, Faserfarbe und Faserfestig­keit dienen.The fiber pattern or rather the fiber pattern beard 11 is in most cases still free of the unclamped fibers by suitable brushing operations. A fiber sample beard 11 prepared in this way can serve as a test specimen for various determinations, such as fiber length, fiber maturity, fiber fineness, fiber color and fiber strength.

Die in Fig. 5 dargestellte Phase der Wiederbereitstellung für die nächste Fasermusterbart-Herstellung beginnt mit dem Auseinander­fahren der beiden Teller 1 und 2. In geöffnetem Zustand werden die in den Garnituren 3 und 4 verbleibenden Fasern 6 unter Zu­hilfenahme von Saug- und/oder Bürstvorrichtungen 9 entfernt und die beiden Teller 1 und 2 wieder in Arbeitsposition (Fig. 1 und 2) gebracht.5 for the next fiber pattern beard production begins with the moving apart of the two plates 1 and 2. In the open state, the fibers 6 remaining in the sets 3 and 4 are made with the aid of suction and / or brushing devices 9 removed and the two plates 1 and 2 brought back into the working position (Fig. 1 and 2).
