Techtextil 2017 – Building for the future with Karl Mayer

Textile reinforcing materials are alternatives to steel reinforcements when building with concrete. Textiles do not rust!

So only a thin covering material is required.This saves on resources, reduces environmental pollution and also enables thin-walled, filigree designs to be produced. Karl Mayer Technische Textilien GmbH (Technical Textiles) can offer the RS MSUS-G weft-insertion warp knitting machine for producing the textiles that are used as an innovative way of reinforcing concrete. This high-speed raschel machine with weft insertion in line with the stitch courses can produce heavy carbon-fibre grids, which are used by members of Tudalit e.V. This association is responsible for the Tudalit trademark-protected brand for maintaining quality standards in the production and use of textile-reinforced concrete. Allgemeine bauaufsichtliche Zulassung (General Building Regulations Approval) has already been applied for to cover certain concrete components containing weft-inserted, warp-knitted textiles.

The textiles produced on the machines manufactured by Karl Mayer Technische Textilien can be used to reinforce the composite materials used in concrete construction, as well as plastic composites. Here, ready-consolidated, fibre-thermoplastic, semi-finished products, so-called organic sheets, have become more important in recent years. According to Jochen Schmidt, the Managing Director of Karl Mayer Technische Textilien GmbH, the concept of fibre spreading is also starting to be a hot topic. Before they are joined to the plastic matrix, the fibre tapes are spread using Karl Mayer’s UD 500 and UD 700 fibre spreading machines. These two machines have already made a name for themselves among composites’ manufacturers for use in the preliminary stages in the production of multiaxial textiles.

High-performance, warp-knitted textiles maximise performance and comfort in the sports and athleisure sectors

Innovative sports- and athleisure-wear provides comfort, enhances performance, looks stylish and offers a performance profile that is backed up by intelligently designed textiles. Stylish, functional stretch and non-stretch textiles are a speciality of Karl Mayer’s warp knitting machines. The company’s high-speed tricot machines, jacquard raschel machines and double-bar raschel machines can produce a variety of structured and openwork designs from a single source, and also work functional zones that can be integrated into a garment, such as a jersey. Zones are created, which provide a defined compression, breathability, warmth retention and freedom of movement. This is based on body mapping principles and the zones are located in exactly the right places. Karl Mayer’s double-bar raschel machines in particular are also setting functional trends when producing seamless items that are making quite a fashion statement.
