"We are pleased that our operational successes and the already advanced trans-formation of SGL Carbon have been honored by the two major rating agencies - Moody's and S&P - by upgrading the ratings. We also see this as a motivation for the further development of SGL Carbon," explains Thomas Dippold, Chief Financial Officer of SGL Carbon SE.

• Swiss weaving machinery manufacturers are in the forefront of novel application development

Shoes and electronic calculators are probably not the first products people would associate with the textile weaving process. But they certainly signpost the future for woven fabrics, as two examples of the ever-wider possibilities of latest technology in the field. Fashion and function already combine in the increasing popularity of woven fabrics for shoes, and this is a present and future trend. Calculators in fabrics? That’s another story of ingenious development, using so-called ‘meander fields’ on the back and keys printed on the front of the material.

These glimpses of the outlook for modern weavers are among the highlights of developments now being pioneered by Swiss textile machinery companies. All weaving markets require innovation, as well as speed, efficiency, quality and sustainability. Member firms of the Swiss Textile Machinery Association respond to these needs at every point in the process – from tightening the first thread in the warp to winding the last inch for fabric delivery. They also share a common advantage, with a leading position in the traditional weaving industry as well as the expertise to foster new and exciting applications.

Technology and research cooperation
The concept of a ‘textile calculator’ was developed by Jakob Müller Group, in cooperation with the textile research institute Thuringen-Vogtland. Müller’s patented MDW® multi-directional weaving technology is able to create the meander fields which allow calculator functions to be accessed at a touch. A novel and useful facility, which suggests limitless expansion.

Today, the latest woven shoes are appreciated for their precise and comfortable fit. They score through their durability, strength and stability, meeting the requirements of individual athletes across many sports, as well as leisurewear. Stäubli is well known as a leading global specialist in weaving preparation, shedding systems and high-speed textile machinery. Its jacquard machines offer great flexibility across a wide range of formats, weaving all types of technical textiles, lightweight reinforcement fabrics – and shoes.

It’s possible to weave new materials such as ceramics, mix fibers such as aramid, carbon and other, and produce innovative multi-layers with variable thicknesses. Such applications put special demands on weaving machines which are fulfilled by Stäubli high-performance TF weaving systems.

Great weaving results are impossible without perfect warp tension, now available thanks to the world-leading electronic warp feeding systems of Crealet. Some market segments in weaving industry today demand warp let-off systems which meet individual customer requirements. For example, the company has recognized expertise to understand that geotextile products often need special treatment, as provided by its intelligent warp tension control system. Individual and connective solutions are designed to allow external support via remote link. Crealet’s warp let-off systems are widely used in both ribbon and broadloom weaving, for technical textiles applied on single or multiple warp beams and creels.

Functional, sustainable, automated
Trends in the field of woven narrow fabrics are clearly focused on functionality and sustainability. The Jakob Müller Group has already embraced these principles – for example using natural fibers for 100% recyclable labels with a soft-feel selvedge. It also focuses as much as possible on the processing of recycled, synthetic materials. Both PET bottles and polyester waste from production are recycled and processed into elastic and rigid tapes for the apparel industry.

For efficient fabric production environments, it is now recognized that automated quality solutions are essential. Quality standards are increasing everywhere and zero-defect levels are mandatory for sensitive applications such as airbags and protective apparel.

Uster’s latest generation of on-loom monitoring and inspection systems offers real operational improvements for weavers. The fabric quality monitoring prevents waste, while the quality assurance system significantly improves first-quality yield for all applications. Protecting fabric makers from costly claims and damaged reputations, automated fabric inspection also removes the need for slow, costly and unreliable manual inspection, freeing operators to focus on higher-skilled jobs.

Smart and collaborative robotics (cobots) offer many automation possibilities in weaving rooms. Stäubli’s future oriented robotics division is a driver in this segment with first effective installations in warp and creel preparation.

Control and productivity
Willy Grob’s specialized solutions for woven fabric winding focus on reliable control of tension, keeping it constant from the start of the process right through to the full cloth roll. Continuous digital control is especially important for sensitive fabrics, while performance and productivity are also critical advantages. In this regard, the company’s large-scale batching units can provide ten times the winding capacity of a regular winder integrated in the weaving machine.

The customized concept by Grob as well as design and implementation result in great flexibility and functionality of the fabric winding equipment – yet another example of Swiss ingenuity in textile machinery.  
There is even more innovation to come in weaving – and in other segments – from members of the Swiss Textile Machinery Association in future! This confident assertion is founded on an impressive statistic: the 4077 years of experience behind the creative power of the association’s member firms. It’s proof positive that their developments grow out of profound knowledge and continuous research.

What does the furniture market look like and what potential composites offer for the furniture of today and tomorrow? The AZL is investigating this question together with companies from the composite and furniture industry. The result will be an overview of the current market and the materials used to date as well as an outlook on future mass applications for fiber-reinforced plastics (FRP). The study is open to interested companies and starts with a kick-off meeting at Composites Europe in Stuttgart on November 7th, 2018.

Furniture, its design and function have undergone major changes in recent decades: From robust lifelong companions to trend-setting models, from handmade one-of-a-kind pieces to mass products, from storage objects to multi-functional and “smart” all-rounders. This goes along with an increased diversity in terms of design and the materials used – and high potential for composites that offer additional design freedom and exceptional mechanical properties at low weight.

Study provides overview of furniture market and unique selling points of composites
In order to systematically identify the potential of fiber-reinforced composites and to use them in future furniture applications, the AZL is starting a study together with companies from the furniture and composite industry. Within four and a half months the market for furniture will be segmented, design and technology trends will be identified and the technical requirements for furniture and furniture components will be broken down to identify applications with high potential for composites. The overall goal is to understand the selection process and needs of the furniture designer in order to bring composites to the market as a targeted alternative to conventional materials.

Virginia Bozsak, Technical Manager Composites at ARKEMA Innovative Chemistry is participating in the study: “The ever-growing population number requires environmentally friendly material and a solution for the end of life treatment to recollect and reuse materials. For fast changing markets such as the furniture market, these materials also need to offer an enormous freedom of design. Arkema already answers this demand with the only liquid thermoplastic resin Elium® used as a thermoset resin to produce composite structural or aesthetical parts. With the joint study, we aim to identify specific applications in the furniture market to make use of material which is not limiting creativity or design specifications but rather enabling the future to be revolutionized.”
