Groz-Beckert develops innovative slider needle for circular knitting machines together with Vanguard Pailung

In collaboration with Vanguard Pailung, a manufacturer of ultra-high-speed knitting machines for body-size products, Groz-Beckert has developed an innovative slider needle for a new generation of machines. The new needle technology was presented for the first time at the ITMA in June 2023.

Groz-Beckert offers interested machine builders various cooperation opportunities to jointly develop new products or improve existing ones. Groz-Beckert's Technology and Development Center (TEZ) provides the appropriate framework for so-called co-development projects. One successful example of a successful cooperation is the development of a new slider needle for circular knitting machines with Vanguard Pailung.

New slide needle technology for higher productivity

In June 2022, Vanguard Pailung approached Groz-Beckert with a cooperation request. Together with Groz-Beckert, the company wanted to develop a new needle solution for an innovative ultra-high-speed machine. Together with an innovative slide needle, the new machine was to exceed the speed and productivity of known knitting systems of large circular knitting machines.

Machine and needle development ran in parallel and were closely coordinated. The first field tests took place in the Vanguard Pailung laboratory in Monroe/NC, USA in February 2023. The successful development was presented to a wide audience for the first time at ITMA 2023 in June.

Unlike latch needles, slide needles do not form the stitch via a needle latch, but via a slide that is controlled by its own channel. The advantage of this is that the needle can withstand high speeds, as there is no latch impact, which in turn increases productivity.

The use of the new slide neelde in ultra-high-speed machines ensures a particularly high level of process reliability. With the new needle variant, the closer is guided safely and precisely in the groove in the needle shank. At the same time, the base of the needle shank is closed, which ensures maximum stability. The slider needle reliably prevents the so-called latch impact and thus makes a decisive contribution to process reliability. Its use ensures a uniform and speed-independent loop structure, even at maximum speeds.

Transparent and open communication, including the shared use of data and design specifications, helped to ensure that the project was a success right from the start.

More Jacquard. More functionality. More fashion.

With the addition of another member to its successful RASCHELTRONIC® family, KARL MAYER is opening up new possibilities for creative product development for warp knitting mills and brands. The RJ 4/2 EL offers with two stitch-forming Jacquard bars entirely new design options for functional sportswear and bi-elastic lingerie. Available in gauges E 28 and E 32, this new model helps manufacturers set their collections apart from the competition. The fine E-32 gauges, in particular, impress with their clean surface, a pleasantly soft feel, and an exceptionally elegant look.

KARL MAYER's HKS 2-SE Expands Possibilities for Premium Stretch WARP KNITS

Warp knitted fabrics with a woven look are more in demand than ever in the fashion and apparel industries. Stretch WARP KNITS, in particular, impress with their freedom of movement, breathability, and virtually wrinkle-free wear – thereby opening up new style worlds such as smart casual or business casual. When it comes to the highly efficient production of premium-quality stretch WARP KNITS, the HKS 2-SE has long been the machine of choice. KARL MAYER’s best-selling tricot machine produces standard elastic fabrics characterized by high gauges, smooth, delicate surfaces, and a soft hand feel.

Footwear innovation enabled by warp knitting technology– insights from New Balance

The future of the athletic shoe is increasingly being shaped on warp knitting machines. For KARL MAYER, the footwear industry is one of the most important growth markets – and one of the sectors where innovative textiles can realize their full potential. In his keynote address at the opening of KARL MAYER’s TEXTILE INNOVATION CENTER in Obertshausen in April, Vishnu Prakash Muthusamy, Senior Textile and Materials Engineer at New Balance, explained the opportunities that warp knitting technology opens up for performance, sustainability, and faster development processes, and why textile manufacturers are transitioning from suppliers to development partners.

EU ban on destroying unsold clothing and footwear now in force

The European Union's ban on the destruction of unsold clothing, clothing accessories and footwear has entered into force. Since July 19, 2026, large companies across the EU have been prohibited from destroying unsold textile products, while medium-sized companies will be required to comply with the same rules from 2030.
