Description

Die Erfindung betrifft Schnittschutzkleidung aus einem Garn mit einem Kern aus Glasfilamenten und einem Mantel aus Aramidfasem.The invention relates to cut protection clothing made from a yarn with a core Glass filaments and an aramid fiber sheath.

US-A- 5,177,948 offenbart ein nicht-metallisches Kompositgarn und daraus hergestellte textile Flächengebilde und Schutzkleidung, wobei diese eine gesteigerte Schnittfestigkeit, Flexibilität und Biegsamkeit aufweisen sollen im Vergleich zu Schnittschutzgamen, die metallische Drähte enthalten. Das Garn der US-A-5,177,948 enthält einen Faserkern und eine Ummantelung, die um den Kern gewickelt ist. Wenigstens ein Strang des Kerns besteht aus Glasfasern und dieser Strang weist einen Titer von 375 bis 1000 den, entsprechend etwa 417 bis 1111 dtex auf. Die um den Kern gewickelte Umhüllung umfaßt mindestens zwei Stränge, die in entgegengesetzten Richtungen zueinander, spiralförmig um den Kern gewickelt sind, und das nicht-metallische Kompositgarn weist einen Gesamttiter von 2000 bis 5000 den, entsprechend 2222 bis 5555 dtex auf. Für die um den Kern gewickelte Umhüllung können Aramidfasern eingesetzt werden, wobei jedoch Polyethylenfasern bevorzugt werden.US-A-5,177,948 discloses and from a non-metallic composite yarn manufactured textile fabrics and protective clothing, this increased Cut resistance, flexibility and flexibility should have compared to Cut protection games that contain metallic wires. The yarn of US-A-5,177,948 contains a fiber core and a sheath that surrounds the core is wrapped. At least one strand of the core consists of glass fibers and this Strand has a titer of 375 to 1000 den, corresponding to about 417 to 1111 dtex on. The sheath wrapped around the core comprises at least two strands which are in opposite directions, spirally wrapped around the core, and the non-metallic composite yarn has a total denier of 2,000 to 5,000 corresponding to 2222 to 5555 dtex. For those wrapped around the core Aramid fibers can be used for cladding, but polyethylene fibers to be favoured.

Das Kompositgarn der US-A- 5,177,948 soll auf konventionellen Strick- oder Webmaschinen zu textilen Flächengebilden verarbeitet werden oder zur Herstellung von Schutzkleidung gestrickt werden. The composite yarn of US-A-5,177,948 is said to be on conventional knitting or Weaving machines are processed into textile fabrics or for production be knitted from protective clothing.

Zum einen ist die Herstellung des Kompositgams der US-A-5,177,948 sehr aufwendig, da zwei Garnstränge um einen Kern gewickelt werden müssen und somit zunächst der Kern, der ebenfalls aus mehreren Garnsträngen bestehen kann, und die zur Umwicklung benötigten Garnstränge separat zur Verfügung gestellt werden müssen und in weiteren Arbeitsgängen gewickelt werden müssen. Dieses Garn sollte zwar einen guten Schnittschutz bieten, aber aufgrund des Aufbaus des Garns sollte dieses schwer auf modernen Strickmaschinen zu verarbeiten sein und zu vergleichsweise steifen Schnittschutzartikeln aufgrund Aufbau und Dicke des Garnes führen.Firstly, the production of the composite yarn of US-A-5,177,948 is very expensive because two strands of yarn have to be wrapped around a core and thus first the core, which can also consist of several skeins of thread, and the yarn strands required for wrapping are made available separately and must be wrapped in further operations. This yarn should offer good cut protection, but due to the structure of the yarn should this is difficult to process on modern knitting machines and too comparatively stiff cut protection articles due to the structure and thickness of the yarn to lead.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, Schnittschutzkleidung zur Verfügung zu stellen, die aus einem Garn besteht, das auf einfache Weise herstellbar ist, und die einen hohen Schnittschutz bei gutem Tragekomfort bietet. Weiterhin soll die Schnittschutzkleidung eine hohe Abriebbeständigkeit aufweisen.The present invention is therefore based on the object of cut protection clothing to provide, which consists of a yarn that is simple is producible, and which offers high cut protection with good wearing comfort. Furthermore, the cut protection clothing should have a high abrasion resistance.

Diese Aufgabe wird bei der eingangs genannten Schnittschutzkleidung dadurch gelöst, dass das Garn ein Faden aus mit Aramidstapelfasern umsponnenen Glasfilamenten ist, wobei der umsponnene Faden einen Gesamttiter von 250 bis 1250 dtex aufweist und der Titer der Glasfilamente 150 bis 450 dtex beträgt.This task is achieved with the cut protection clothing mentioned at the beginning solved that the yarn is a thread made of aramid staple fibers Is glass filaments, the wound thread has a total titer of 250 to Has 1250 dtex and the titer of the glass filaments is 150 to 450 dtex.

Der Gewichtsanteil der Glasfilamente sollte 30 bis 60 %, bevorzugt 40 bis 50 % des Gesamtgewichts des umsponnenen Fadens betragen. Als Gesamttiter des Fadens werden 400 bis 800 dtex bevorzugt. Bei dem angegebenen Titer der Glasfilamente handelt es sich jeweils um den Gesamttiter eines multifilen Glasfilamentgarnes, der erfindungsgemäß 150 bis 450 dtex, bevorzugt 200 bis 350 dtex beträgt.The proportion by weight of the glass filaments should be 30 to 60%, preferably 40 to 50% of the Total weight of the wound thread. As total titer of the thread 400 to 800 dtex are preferred. At the specified titer of the glass filaments is the total titer of a multifilament glass filament yarn, the according to the invention is 150 to 450 dtex, preferably 200 to 350 dtex.

Die Schnittschutzkleidung wird insbesondere aus dem umsponnenen Faden gestrickt. Besonders vorteilhaft ist es, wenn zwei umsponnene Fäden miteinander verzwirnt sind, da damit eine höhere Abriebbeständigkeit der daraus hergestellten Schnittschutzkleidung erzielt wird. The cut protection clothing is made especially from the wound thread knitted. It is particularly advantageous if two wound threads together are twisted, as this means that the abrasion resistance of those made from them is higher Cut protection clothing is achieved.

Der Faden aus mit Aramidstapelfasern umsponnenen Glasfilamenten kann besonders vorteilhaft nach dem Friktionsspinnverfahren hergestellt werden. Damit ist eine kostengünstige Herstellung des Fadens in einem Arbeitsgang möglich. Zur Herstellung des Fadens können Friktionsspinnmaschinen wie sie unter dem Namen DREF 2, DREF 2000 von der Textilmaschinenfabrik Dr. Ernst Fehrer AG verkauft werden oder wie sie beispielsweise in DE-A-37 41 783 beschrieben sind, eingesetzt werden.The thread made from glass filaments covered with aramid staple fibers can be produced particularly advantageously by the friction spinning process. So that is an inexpensive production of the thread possible in one operation. to Manufacturing the thread can use friction spinning machines like the one under the name DREF 2, DREF 2000 from the textile machine factory Dr. Ernst Fehrer AG sold are used or as described for example in DE-A-37 41 783 become.

Bei der Schnittschutzkleidung handelt es sich insbesondere um einen Schnittschutzhandschuh, aber auch Armschützer oder Unterarmschützer sind möglich.The cut protection clothing is in particular one Cut protection glove, but also arm guards or forearm protectors possible.

Mit dem erfindungsgemäß eingesetzten umsponnenen Faden lassen sich Schnittschutzkleidungsstücke von vergleichsweise geringem Gewicht herstellen, was deren Tragekomfort erhöht. So beträgt das Gewicht eines Schnittschutzhandschuhs beispielsweise 15 bis 40 g, insbesondere nur 15 bis 25 g.With the wound thread used according to the invention, Cut protection clothes of comparatively light weight what their comfort increases. So the weight of a cut protection glove is for example 15 to 40 g, in particular only 15 to 25 g.

Zur Herstellung von gestrickten Handschuhen werden bevorzugt sogenannte Handschuhstrickautomaten eingesetzt, wie sie z.B. von den japanischen Firmen Shima Seiki oder Matsuya vertrieben werden. Diese Strickautomaten werden mit verschiedenen Nadelteilungen angeboten:

7 gauge:
für relativ grobe, schwere Handschuhe
10 gauge:
für leichte Handschuhe, die bereits eher ein handschuhloses Gefühl verleihen sollen
13 gauge:
für sehr leichte Handschuhe
14 oder 15 gauge:
für ultra leichte / ultra dünne Handschuhe.
So-called glove knitting machines, such as those sold by the Japanese companies Shima Seiki or Matsuya, are preferably used to produce knitted gloves. These knitting machines are offered with different needle pitches:
7 gauge:
for relatively coarse, heavy gloves
10 gauge:
for light gloves, which should give a gloveless feeling
13 gauge:
for very light gloves
14 or 15 gauge:
for ultra light / ultra thin gloves.

Schnittschutzhandschuhe der vorliegenden Erfindung werden bevorzugt mit Nadelteilungen von 10 und 13 gauge hergestellt. Es handelt sich damit um leichte bis sehr leichte Handschuhe, die mit dem Garn gemäß US-A-5,177,948 nicht hergestellt werden können, da das darin beschriebene Garn ein hohes Gewicht aufweist und inhärent eine zu hohe Steifigkeit besitzt. Auch sollte eine Verarbeitung mit einer Nadelteilung von 10 gauge und insbesondere von 13 gauge bei einem Gesamttiter des Kompositgarns von mindestens 2000 den kaum zu realisieren sein.Cut resistant gloves of the present invention are preferred with Needle pitches of 10 and 13 gauge made. It is easy to very light gloves that are not made with the yarn according to US-A-5,177,948 can be because the yarn described therein is heavy and inherently too stiff. Processing with a Needle division of 10 gauge and in particular of 13 gauge for a total titer of the composite yarn of at least 2000 den can hardly be realized.

Im folgenden wird die Erfindung anhand von Beispielen näher erläutert und beschrieben.The invention is explained in more detail below with the aid of examples and described.

Die Eigenschaften von Schnittschutzhandschuhen werden gemäß der Norm DIN EN 388 (1994) "Überprüfung von Schutzhandschuhen gegen mechanische Risiken" gemessen, und die nach der Norm bestimmte Abriebfestigkeit, Schnittfestigkeit, Weiterreißfestigkeit und Durchstichkraft werden in Leistungsstufen 1 bis 5 klassifiziert, wobei die Eigenschaften eines Schutzhandschuhs umso besser sind, je höher die Leistungsstufe ist, in die er klassifiziert ist.The properties of cut protection gloves are in accordance with the standard DIN EN 388 (1994) "Checking protective gloves against mechanical risks" measured, and the abrasion resistance, cut resistance, Tear resistance and puncture resistance are in performance levels 1 to 5 classified, the properties of a protective glove are the better, depending higher is the power level in which it is classified.

Auf einer Strickmaschine mit 7 gauge Nadelteilung wurde ein Handschuh gestrickt. Der dazu eingesetzte Faden aus mit Aramidstapelfasern umsponnenen Glasfilamenten wies einen Gesamttiter von 2630 dtex auf. Der Titer der Glasfilamente betrug 680 dtex und ihr Gewichtsanteil 26 %. Eine Verzwirnung zweier Fäden erfolgte in diesem Beispiel nicht. Gemäß DIN EN 388 konnte auch dieser Handschuh, der ein Gewicht von 36,6 g aufwies, in Klasse 5 hinsichtlich Schnittschutz klassifiziert werden. In Bezug auf Abriebbeständigkeit wurde er jedoch nur in Klasse 1 eingestuft. Für die Praxis ist jedoch nicht nur ein hoher Schnittschutz sondern auch eine hohe Abriebbeständigkeit von Bedeutung, da diese für die Lebensdauer des Handschuhs maßgeblich ist. Somit erfüllt der Handschuh dieses Beispiels nicht die Forderungen, die an einen qualitativ guten Schutzhandschuh gestellt werden.A glove was knitted on a knitting machine with 7 gauge needle pitch. The thread used for this is made of aramid staple fibers Glass filaments had a total titer of 2630 dtex. The titer of the Glass filaments were 680 dtex and their weight percentage was 26%. A twist of two No threads were used in this example. According to DIN EN 388, this too Glove, which weighed 36.6 g, in class 5 with regard to Cut protection can be classified. In terms of abrasion resistance, however, it was only classified in class 1. In practice, however, it is not just a high level of cut protection but also a high resistance to abrasion, which is important for the Glove life is decisive. So the glove fulfills this For example, not the demands on a good quality protective glove be put.

Vergleichsbeispiel 2:Comparative Example 2:

In einem weiteren Vergleichsbeispiel wurde auf einer Strickmaschine mit 10 gauge Nadelteilung ein Handschuh gestrickt. Der dazu eingesetzte Faden aus mit Aramidstapelfasern umsponnenen Glasfilamenten wies einen Gesamttiter von 360 dtex auf. Der Titer der Glasfilamente betrug 110 dtex und ihr Gewichtsanteil 30 %. Jeweils zwei umsponnene Fäden wurden miteinander verzwirnt, und jeweils zwei miteinander verzwirnte Fäden wurden parallel der Strickmaschine zugeführt. Gemäß DIN EN 388 konnte dieser Handschuh, der ein Gewicht von etwa 22 g aufwies, nur in Klasse 1 hinsichtlich Schnittschutz klassifiziert werden, womit der Handschuh den von der Industrie geforderten Schnittschutzstandard nicht erfüllt.In a further comparative example, a knitting machine with 10 gauge Needle pitch knitted a glove. The thread used for this from Glass filaments spun around aramid staple had a total titer of 360 dtex on. The titer of the glass filaments was 110 dtex and their weight fraction 30%. Two wound threads were twisted together, and two each threads twisted together were fed in parallel to the knitting machine. According to This glove, which had a weight of about 22 g, could only meet DIN EN 388 in Class 1 with regard to cut protection, with which the glove is Cut protection standard required by industry not met.
