High performance carbon fibre yarns for knitting and sewing

Carbon fibre specialist SGL Group has started production of stretch-broken carbon fibre yarns, which have knitting and sewing applications, at its facility in Muir of Ord in Scotland. Most carbon fibre yarns produced by the company go into wovens and multi axial fabric applications for carbon fibre reinforced composites.

Carbon fibre specialist SGL Group has started production of stretch-broken carbon fibre yarns, which have knitting and sewing applications, at its facility in Muir of Ord in Scotland.  Most carbon fibre yarns produced by the company go into wovens and multi axial fabric applications for carbon fibre reinforced composites.

An official ceremony inaugurating the new production took place on November 7, 2013, where site management, local politicians and media representatives were in attendance to celebrate the milestone event.

Marketed under the brand name SIGRAFIL C SBY, the high-performance, very fine stretch-broken carbon fibre yarn is a proprietary development of SGL Group, which was first presented to the general public at this year’s JEC Composites Show in Paris, France.

SIGRAFIL C SBY is said to offer a broad range of applications and can be used as a heat conductor due to its electrical resistance. It can also be used as sewing yarn or knitting yarn and is also said to be well suited for applications where carbon fibre composite parts are exposed to very high service stresses, such as in the automotive applications.

In addition to the characteristic properties of carbon fibre such as high strength, light weight and temperature resistance, the new yarn is said to provide excellent knot and loop strength. According to SGL the optimized yarn properties allow for new opportunities in textile processing, such as sewing and knitting processes where regular multifilament carbon fibre previously reached its limits.

Dr. Andreas Wöginger, Product and Technology Management SGL Group commented: “We are expanding our existing value chain by developing new textile procedures and refining our SIGRAFIL C carbon fibre into a fine yarn.  We are now positioned to offer our customers new and innovative material concepts that meet the growing market requirements.”

SGL Group is one of the world’s leading manufacturers of carbon-based products and materials. It has a comprehensive portfolio ranging from carbon and graphite products to carbon fibres and composites. SGL Group’s core competencies are its expertise in high-temperature technology as well as its applications and engineering know-how gained over many years.

Products from SGL Group are used predominantly in the steel, aluminum, automotive and chemical industries as well as in the semiconductor, solar and LED sectors and in lithium-ion batteries. Carbon-based materials and products are also being used increasingly in the wind power, aerospace and defence industries.

In 2009, SGL Automotive Carbon Fibers (ACF), a joint venture between the BMW Group and SGL Group was founded for the exclusive supply of carbon fibre materials to the BMW Group for its new generation range of cars.

With 45 production sites in Europe, North America and Asia as well as a service network covering more than 100 countries, SGL Group is a company with a global presence. In 2012, the company’s workforce of around 6,700 employees generated sales of €1,709 million. The company’s head office is located in Wiesbaden, Germany.
