In the sports sector, where synthetic fibers are predominantly used, an increasing environmental awareness and end-of-life considerations are triggering new innovations. The innovative double-layer knit made of 100 % cellulosic fibers consists of kapok fibers on the inside and Tencel Modal fibers with Eco Color technology (a very resource-saving technology for embedding color pigments during fiber production) on the outside. It sets new standards in the field of biodegradable performance materials as, in contrast to fabrics made from synthetic fibers, it biodegrades or can be used as feedstock for new products. While the hollow kapok fibers have hydrophobic properties, Tencel Modal fibers transport the moisture to the outer layer, distribute it and thus contribute to a better drying performance. The range of double needle bar raschel machines by Karl Mayer Textilmaschinenfabrik GmbH, Obertshausen/Germany, has been extended to models that produce spacer fabrics in tried-and-tested thicknesses but at new working widths. After launching an RD 7 with a new knock-over comb bar distance (from 2-6 mm), the RD 7/2-12 EN (7-bar) and RD 6/1-12 EN (6-bar) are available now in a working width of 190 (4.8 m). The 7-bar machine was previously available in working widths of 77 (1.95m)and 138 (3.5 m), while the 6-bar equivalent was available as a 138 variant. Apart from the expansion in width, there were no other changes. Both 190 machines achieve an unchanged speed of 850 courses/min, which means an increase in productivity of 37% compared to the narrower 138 versions. The width of the Highdistance has also been upgraded: the HD 6/20-35 was added to Karl Mayer's product portfolio with a 160 (4 m) version. By extending the working widths, 2 panels can now be produced simultaneously next to each other instead of singularly, or 3 fabric lines instead of 2, for example. The RD 7/2-6 EN offers the footwear fabric market a high-speed machine with a speed of 1,100 stitch courses/min. The 138" RD 7/2-12 EN is suitable for a wide range of applications, from footwear fabrics to articles for upholstered furniture and mattresses. The 190 versions of the RD 7/2-12 EN and RD 6/1-12 EN, meet the special requirements of the mattress market.
