Sleewitex® - das ideale Core-Garn

Sleewitex ist DAS ideale Coregarn. Das Filament befndet sich genau in der Mitte, die Stapelfasern gleichmäßig darum verteilt für eine perfekte Abdeckung des Filaments. Somit scheint das Filament nicht durch die Stapelfasern hindurch.

Hohe Festigkeit mit textilem Griff

Bei Sleewitex® bestimmt hauptsächlich das Filament die Zugfestigkeit des Garns. Die textile Haptik kann jedoch durch die Stapelfasern an der Außenseite vollständig erhalten bleiben. Somit können starre Filamente mit einem unangenehmen textilen Griff komplett abgedeckt werden. Die jeweiligen Eigenschaften von Filament und Stapelfasern können voll ausgeschöpft werden. Das Filament sorgt für die mechanischen Eigenschaften, die Stapelfasern für den angenehmen Griff.

Neue Spinntechnologie

Da Sleewitex® ein ideales Core-Garn darstellt, ist auch die Zuführung des Filaments vergleichbar. Das Garn wird direkt im Ringspinnverfahren hergestellt. Der Unterschied zu Standard Coregarn stellt die patentierte Spinntechnologie dar. Dabei läuft das Filament über die Filamentwalze und fügt sich am Klemmpunkt mit den Stapelfasern zusammen. Durch eine spezielle Ausformung der Walze kann das Filament ohne Klemmung mit einer speziell eingestellten Zuführgeschwindigkeit einlaufen. Dadurch können sich die Stapelfasern gleichmäßig um das Filament legen und es somit vollständig überdecken.

Anwendungen im Schnittschutz und für Smart Textiles

Das Sleewitex® Garn wird erstmalig zur Messe vorgestellt. In Grundlagenversuchen wurden verschiedene Anwendungsbereiche ausgelotet. Erste Entwicklungen befassten sich mit dem Schnittschutz. Dabei wurden Filamente aus Metall oder Dyneema im Kern verarbeitet und mit Polyesterstapelfasern abgedeckt. Somit kann das Garn in beliebig vielen Farben der Anwendung angepasst werden: die Polyesterfasern im Mantel werden gefärbt und überdecken die darunter liegenden Filamente. Für eine hohe elektrische- oder Wärmeleitfähigkeit bietet sich ein Metallfilament auch für die Anwendung in Smart Textiles an.

Thermoplastisch umformbares Garn

Getestet wurde auch eine Anwendung mit thermoplastischen Filamenten im Kern des Garns. Gestricke und Gewebe aus diesem Material können mittel Wärme und Druck umgeformt werden und dadurch als Bauteile mit textilem Griff fungieren. Somit könnten Kunststoffteile durch Flächengebilde mit schönem textilen Griff ersetzt, neue Designs für Möbel und Interior erzeugt  und Halbzeuge für die unterschiedlichsten Anwendungen hergestellt werden.

Denkbar sind auch die Herstellung von Halbzeugen in Faserverstärkten Kunststoffen. Hier können die Stapelfasern als zusätzlicher mechanischer Haftvermittler zwischen Filament und Matrix dienen. 

TRIWITEX® High-strength and durable

A specially developed spinning method

TRIWITEX® is based on a core yarn technology. This technology harnesses the benefits of wool and other natural and synthetic fibres to develop durable, long-lasting and functional yarns for various applications. Compared to conventional spinning methods, each TRIWITEX® yarn ensures improved strength, high abrasion resistance and virtually no pilling.

Conventional fibre yarns are spun around a robust filament. The TRIWITEX® covering method adopts a truly innovative approach. Previously used as the core, the filament is spun around the fibre and is now on the outside. As the new core, the fibre is then located on the inside and is therefore ideally protected.

A TRIWITEX® yarn with wool core and synthetic fibre filament exclusively preserves the positive properties of wool, while eliminating the negative aspects. This is made possible by the synthetic fibre filament, which binds the protruding wool fibres in the yarn and at the same time improves its abrasion resistance and tensile strength compared to pure wool yarn. Among the most striking effects is the greater durability of the TRIWITEX® yarn.

Pilling Abrasion

This is most evident in the susceptibility of textile surfaces to pilling. A fabric made of TRIWITEX® satisfies the strictest requirements here. The results of the pilling test (DIN EN ISO 12945-2), as shown in the comparison above, indicate that TRIWITEX® scores the top mark of 5.

A comparable fabric (industry standard) achieves only 3 under identical conditions. Qualified personnel use a standardised visual inspection to award marks on the test scale of 0–5.

Martindale abrasion test

The Martindale test is a method to determine the abrasion resistance of textile surfaces. A high abrasion cycle value indicates good durability.

The method simulates natural wear acting on a fabric by applying a prescribed weight load and then rubbing a sample of the test material against a standardised test fabric. The number of abrasion cycles (standard unit of measurement) are counted until a hole forms in the surface. In principle, Materials with a higher value are more durable.

A targeted mix of fibres and filaments is not enough to achieve the increased useful life and abrasion resistance. What’s more, the clever positioning of the filament within the yarn composite has a significant influence quality of the TRIWITEX®.

A yarn for every use case

TRIWITEX® yarns are extraordinarily versatile and are therefore compatible with a broad variety of industries and uses. The highly individual requirements and scenarios of each sector are no problem for TRIWITEX®. After all, the flexible combination of materials means that our development department can help to satisfy even unusual requirements that were beyond the reach of conventional spinning methods. With TRIWITEX® technology, lower grammage is achieved with the same durability, as finer yarns can be used due to the greater strength. Besides the technology’s added performance, a TRIWITEX® yarn also preserves its pleasant textile feel. The spun fibres create this “textile feel”. This is a decisive advantage compared to pure filaments, as it is usually impossible to mix materials into the yarn, which means that the textile feel is missing.

Protection

With our large portfolio of functional yarns, we are able to meet the highest technical demands of our customers and comply with safety standards and guidelines. Materials can be selected to suit the application and then customised individually. A wide variety of functions can be added in this process, including heat and cut protection, antistatic qualities and protection against mechanical effects. In areas with defined safety guidelines and standards, a TRIWITEX® yarn can improve comfort by reducing the garment weight, while still preserving the required functionality.

Mobility

In the area of mobility, our yarns are used to make woven and knitted fabrics for all kinds of vehicles. They offer a wide range of application options as seat covers in aeroplanes, buses, trains and in the automotive sector. Resilience is a key factor in the mobility segment to ensure that the seat covers preserve their high-quality look for a long time. TRIWITEX® raises the bar in this regard thanks to its excellent abrasion resistance. All requirements are exceeded by far – depending on the mixture and the woven or knitted structure. TRIWITEX® possesses outstanding properties, especially when used in knitted fabrics.

Corporate

Our long-standing expertise in the area of corporate and professional apparel combines the high requirements of textile durability and comfort with fashionable appeal. Our yarns are designed specifically for these purposes and are therefore suitable for authorities, transport companies, the police and similar segments.TRIWITEX® technology extends the service life of the yarn and therefore the clothing as well. This prolongs the use of workwear, as the yarn performance also allows for longer intervals between washing cycles. Moreover, the material retains its look and feel for longer.TRIWITEX® yarn possess the same properties as conventional yarn, but at a lower grammage, making professional apparel both lighter and more functional. The garments are therefore more comfortable to wear and possess consistent, long-lasting quality.

Industry

Textile products made of TRIWITEX® yarn can also replace conventional fabrics in industrial settings. Yarns can be designed specifically to meet requirements, thanks to the variable selection of core and sheath materials.

Interiors

Materials used in interior design especially need to preserve their great look for a long time. We can accommodate this requirement with our TRIWITEX® technology. It improves abrasion resistance and resilience to ensure long-lasting use. TRIWITEX® is therefore ideal for public buildings and hotels, although it is excellent for use in private homes as well. Among the most striking qualities of TRIWITEX® is its excellent abrasion resistance that preserves the function and look of furnishings and fittings for a long time. TRIWITEX® greatly outperforms the recommended values for textiles used in public spaces. The use of wool and other precious fibres, combined with a sheath material, gives your chairs and sofas a particularly comfortable appeal. Targeted functionality such as anti-odour or anti-bacterial properties are also possible. Naturally, you want your products to preserve their good looks and natural charm for a long time. Textile surfaces made of TRIWITEX® yarn have extended useful lives, while still preserving their charisma. The fabric retains its colour and look for a longer period and continues to feel wonderful.

Fashion

TRIWITEX® is suitable for sustainable production thanks to the demonstrable durability of the yarns. The variable use of environmentally friendly resources is an another beneficial factor for the fashion industry.
