Warp-knitted fabrics are extremely versatile as far as their designs and constructions are concerned, and they can also be engineered to have specific strength values. The reinforcing yarns are mainly responsible for producing the high load-bearing capacity. These extremely stable yarns can be incorporated in line with the courses; they therefore lie at an angle of 90º in the textile, and are inserted as full wefts in this case. The types of constructions produced in this way include insect-repellent nets, lightweight yet dense shading and screening materials, high-quality warp knits for soft furnishings, and a variety of interlinings.
KARL MAYER’s high-speed tricot machines with parallel weft insertion are used for efficiently producing textiles that are mainly used in semi-technical and technical applications. This traditional company is a market leader in the production of warp knitting machines with magazine weft facility, and is continuously improving and expanding its range of products. At the beginning of this year, this manufacturer launched the HKS MSU S machine onto the market as part of a new generation of machines. This revamped machine incorporates a number of optimised features, thus giving the user access to an even greater range of applications than its predecessor. These improved performance features relate to the flexibility, but especially the productivity. The parameters that illustrate the success of KARL MAYER’s development work include a fabric width of 6.27 m, even at a gauge of E 28, and a productivity rate of 2,000 m² fabric/hr. A wide range of yarns can also be processed. At one time, viscose and acrylic spun yarns were typically used as the weft, but now extremely fine yarns, such a polyester filament yarns with a count of 17 dtex, can now be used – similar to the ones used as knitting yarns.
The new HKS MSUS S not only enables a wider range of yarns to be processed, it is also more versatile when it comes to incorporating the reinforcing yarns. Even long underlaps, e.g. in an arrangement of 1-0/4-5//, can be processed without any problems. Selecting the option, ‘weft repeat’, enables yarns to be incorporated only at the points at which they are actually needed. Zones having different densities can also be alternated with each other, and the segments produced can be configured to have specific widths. The transition from open to dense knitted constructions can therefore be worked very smoothly. The Multi Speed function is needed to do this. And practical textiles can also be attractive. Atlas net lappings can be used to make the weft-inserted fabrics more attractive. The use of lustrous yarns produces elegant fabrics, whereby the weft yarns on the inside do a sterling job and also look attractive on the outside.
