KARL MAYER launches eco-friendly indigo dyeing technology at ITMA 2019, booth 8.0/B107

At ITMA 2019, KARL MAYER launches GREENDYE, an innovative technology for producing jeans fabrics with minimized ecological footprint, thus, opening up another market sector, SUSTAINABLE DENIM.

Dyeing in nitrogen atmosphere

The nitrogen technology ensures less environmental impact and more efficiency during indigo dyeing. With its high concentration in the dye bath and under nitrogen atmosphere, the dye diffuses and migrates more intensely into the fibre than in case of conventional comparable procedures. The yarn can absorb three times more dye in a dye vat. In this way, it is possible to reduce the number and length of vats, with positive effects for the environment. The chemical consumption can be reduced considerably, a minus of 50% is possible when using hydrosulphite and caustic soda, and there is also less yarn waste. Moreover, due to the good fixation of the dyestuff on the fibre, considerably less water is required during the washing process.

Production with reproducible parameters

KARL MAYER took over the patents for the innovative indigo dyeing technology from MASTER in 2018. There followed extensive works for the further development and fine tuning. One of the milestones in this context was the putting into operation of a pilot machine at the Denim Competence Center in Mezzolombardo, Italy, at the beginning of this year.

The dyeing system maps the industrial production process at a scale of 1:10 and it has already supplied the first warp beams. These beams were processed by an Italian partner from the weaving industry, the result being highly promising jeans samples. Enzo Paoli, Managing Director of KARL MAYER ROTAL, wants to use these fabrics in order to gain the interest of denim manufacturers in the innovative GREENDYE technology. „Only with samples produced under realistic fix running parameters we can convince on the market. Our contact partners are textile manufacturers, who want something to touch“, says this experienced company boss.

Fabric samples, an animation of the machine and its contribution to the topic of sustainability belongs to the highlights of KARL MAYER’s exhibition stand 8.0/B107 at ITMA 2019. Further steps are already planned. As from September 2019, KARL MAYER will have a new Denim Customer Center, and wants to invite the sector to carry out processing tests on the innovative nitrogen unit.

Sustainable, lightweight, and sound absorbing: Polyester-based front trunk solution for BEVs

As car manufacturers look to further reduce their carbon footprint, Autoneum has developed an innovative front trunk solution for battery electric vehicles (BEVs), made entirely from polyester-based textile. The Ultra-Silent Frunk offers significant weight reduction, improved acoustic and thermal insulation, and uses up to 70 percent recycled material, supporting sustainable and efficient vehicle design. Autoneum, global technology leader in acoustic and thermal management for vehicles, has already received orders for the new frunk from three major OEMs in Asia and Europe to be built in three BEV models. Series production for two BEVs has been underway in China and Germany since last year.

Modern testing methods for raw cotton

The 38th International Cotton Conference Bremen will take place from 25 to 27 March 2026 at the Bremen Parliament. This conference has traditionally stood for in-depth expertise and international exchange. The program will focus on technical innovations, market trends, and regulatory frameworks across the entire value chain – from agriculture to the circular economy. With high-profile speakers, the conference is regarded as the key meeting point for the global cotton industry. Today’s focus: Cotton quality and testing methods.

Rieter responds to higher raw material prices

Global political and economic developments have been leading to rising raw material and energy costs for some time. The textile machinery industry is also affected by this trend. Rieter machines and components consist to a large extent of steel, copper, aluminum and electronics. These materials in particular have seen higher demand and higher prices in recent months.
