At the Techtextil 2019 in Frankfurt/Germany, Karl Mayer Textilmaschinenfabrik GmbH, Obertshausen/Germany, will be showcasing warp-knitted textiles with a special performance.

Karl Mayer will be showcasing products with integrated electrical conductivity and shaping characteristics from the new Textile Makerspace platform, a highly efficient textile solution for protecting buildings, and a completely new generation of warp-knitted spacer textiles. In addition, the company is also inviting people to attend an in-house show, to be held at the same time as the fair, in nearby Obertshausen. This event is easily accessible by bus transfer and will be premiering a new nonwovens machine for the visitors.
The digital solutions grouped under the KM.ON brand, and will also be showcased at the Techtextil.

Rapid Textile

Textiles with a very high performance and lower manufacturing costs can be produced by combining the possibilities of additive production with warp knitting technology. Examples of this include warp knits functionalized by 3D printing.
Karl Mayer has grouped together all its activities relating to the use of new technologies and innovative products under the concept of Rapid Textile. They form part of the Textile Makerspace system, a platform that offers the space to try things out, develop new products and think outside the box.

Textile Circuit

Electrically conductive textiles are a hot topic in the industry and can be produced in a variety of different ways. The easiest method is to directly incorporate conductive yarns during fabric production on the machine. Textile Circuit shows the potential of warp knitting here. Conductive zones offering maximum flexibility in terms of geometry, dimensions and location can be produced on the multi-bar raschel machines. Examples include inductive charging stations and the remote control of robots, which will be demonstrated at Techtextil.

New solutions for patterns with plastic effects

Double-bar raschel machines have become firmly established in the production of warp-knitted spacer textiles featuring a variety of designs. A new model is now enabling completely new designs to be produced, i.e. warp-knitted textiles with decorative, relief surfaces. Instead of the spacer layer, 3-dimensional design elements are worked on the upper and lower sides. The designs can be shaped and positioned almost without any restrictions, and can be combined with openwork designs. This is opening up a new dimension in near-net-shaped production in particular.

Security panels made from weft-inserted warp-knitted textiles

Burglars frequently use chainsaws and drills during attempted break-ins, but they can be stopped effectively by a new type of patented security panel with weft-inserted warp-knitted textiles in the core. On contact with the cut-resistant textiles, the rotating tools quickly release large amounts of fibers from the material. These become entangled and the tool is stopped. The highly effective security panels are also very light and can be applied very easily to e.g. security doors, armored vehicles, vaults and cash machines.

New raschel machine for web bonding

A model in the new Racop-NW series will be demonstrated at the in-house show in Obertshausen, which offers many technological advantages. This process produces nonwovens with textile characteristics such as elasticity and voluminosity, which is not the case when using chemical bonding agents. Furthermore, much less energy is consumed compared to thermal processes. In addition to these general advantages, the new machine also offers an a very good price:performance ratio. It is also very flexible and can therefore be used in a variety of applications. A Racop-NW, 160", gauge E 14, will be producing a textile for the application area heating textiles at the in-house show.
