Trützschler: TC 19i sets the benchmark for energy-efficient carding

Global energy consumption reached a record high in 2019, following a 40-year trend for rapidly increasing energy demand that was only halted by the Coronavirus pandemic. It’s estimated that more than 80 % of this energy is still generated from fossil fuels that produce CO2 emissions and contribute to climate change. Renewable energy offers a solution to this problem, but saving energy whenever possible is an even more effective approach. That are the motives for Trützschler to develop the intelligent card TC 19i, which sets a new benchmark for energy-efficient carding.

The intelligent Trützschler card TC 19i features the unique T-GO gap optimizer, which continuously and automatically monitors and adjusts the carding gap to an ideal position during production. Innovative drive- and air technology further reduce energy consumption of the TC 19i.

The intelligent Trützschler card TC 19i features the unique T-GO gap optimizer, which continuously and automatically monitors and adjusts the carding gap to an ideal position during production. Innovative drive- and air technology further reduce energy consumption of the TC 19i.

The most energy-intensive elements in a carding machine are the drive, the dust suction process and the compressed air system. Permanent suction is needed to remove dust and cotton waste in key places. Smart optimization of these areas has made the intelligent card TC 19i a benchmark for energy efficiency in carding because it uses less electricity, lower suction pressure and less compressed air than other machines, while providing the highest production rates currently available on the market.

In a head-to-head comparison between the TC 19i and a high-performance card from a competitor, the TC 19i consumed at least 10 % less energy per kilogram of material produced when manufacturing rotor yarn from a cotton and cotton waste mix. The compared energy values included electric power consumption and energy required for suction and compressed air and were measured in both cards at the same production of 180 kg/h. A 10 % reduction in energy per kilogram of sliver produced, as proven here by TC 19i, can have a significant impact on a spinning mill’s profitability; annual savings worth a five-digit sum are frequently possible, depending on factors such as the output of the mill. The customer trial also showed TC 19i’s excellent reliability at the customer’s usual production rate of 180 kg/h, and even demonstrated stable performance at 300 kg/h in the same application. Because the TC 19i with T-GO gap optimizer realizes maximum production rates at no compromise in quality, manufacturers can reduce their energy demand and investment costs drastically: Less machines are needed to achieve the desired output, and energy consumption per production is reduced.

This improvement was made possible by a long and sometimes challenging innovation process involving mathematical models of air flows, as well as flow simulations and prototypes. By combining the final flowoptimized parts in the TC 19i, Trützschler’s experts have developed a card that operates with suction pressure of just -740 Pa and with an air requirement of only 4200 m³/h. This translates into 40 % less energy demand for air technology compared to the latest high-performance competitor model.

Kornit Digital: 2020 Impact and Environmental, Social, and Governance Report released

Kornit Digital Ltd., a worldwide market leader in digital textile production technologies, released its 2020 Impact and Environmental, Social, and Governance (“ESG”) Report. This inaugural report affirms Kornit’s commitment to achieving specific ESG goals. This includes the way Kornit conducts business, creates meaningful impact in local communities, and achieves environmental sustainability, in addition to how Kornit will continue to build a diverse and inclusive company culture, foster employee growth and development, and empower fair and safe labor practices globally.
 

Kornit Digital Ltd., a worldwide market leader in digital textile production technologies, released its 2020 Impact and Environmental, Social, and Governance (“ESG”) Report. This inaugural report affirms Kornit’s commitment to achieving specific ESG goals. This includes the way Kornit conducts business, creates meaningful impact in local communities, and achieves environmental sustainability, in addition to how Kornit will continue to build a diverse and inclusive company culture, foster employee growth and development, and empower fair and safe labor practices globally.
 
In addition to enabling eco-friendly production processes with technology and consumables that use less water, reduce waste, and minimize the carbon footprint, Kornit technology solutions enable sustainable production on demand, which eliminates overproduction of apparel and other textile goods. A 2021 Life Cycle Assessment conducted on two flagship products, the Kornit Atlas MAX and Kornit Presto S, demonstrated that relative to traditional analog processes, Kornit’s digital production systems used up to 95% less water and 94% less energy, and produced up to 83% less greenhouse gas (GHG) emissions for the Presto S system and up to 93% less water and 66% less energy, and produced up to 82% less greenhouse gas (GHG) emissions for the Atlas MAX system.


Based on this study, in addition to past sustainability performance results and strategic projections for business growth and market expansion, by 2026 Kornit Digital’s sustainable on-demand solutions are expected to enable the production of approximately 2.5 billion apparel items in a responsible manner to deliver:

  • Zero overproduction: By moving the industry to on-demand manufacturing, Kornit will help eliminate the estimated 1.1 billion apparel items overproduced using traditional production methods, based on an industry average of 30% overproduction. This is about 1 apparel item for each and every person living in Europe and North America – saved.
  • Zero water waste: In addition to eliminating overstocks, Kornit-enabled production on demand will support saving an estimated 4.3 trillion liters (1.1 trillion gallons) of water. This is the estimated amount of drinking water needed for the entire U.S. population for 11 years.
  • Reduced CO2 emissions: By enabling sustainable on-demand production, consuming less energy, and generating less waste, Kornit will prevent an estimated 17.2 billion kilograms (37.9 billion pounds) of greenhouse gas emissions, compared to traditional manufacturing methods. This is equivalent to the estimated amount of carbon dioxide emitted from circumnavigating the entire planet with a car nearly 2,400 times.

Furthermore, the report outlines Kornit’s commitment to achieving KPIs that address waste, chemicals, GHG emissions, energy, product development, employee training, diversity and inclusion, and the company’s supply chain.

WEKO has taken over RotaSpray GmbH

Weko Holding GmbH has taken over RotaSpray GmbH from Oehringen with retroactive effect from January 1st, 2021 and further expands its textile segment.

With the merger of the two companies, the competencies in the field of functional wet finishing, digital printing pre-treatment and spray dyeing processes will be bundled for the textile segment. Both companies believe that these segments offer good future opportunities, because the demand for a resource-saving, CO2-reduced dyeing and finishing process for textile yarns and fabrics is increasing rapidly. Likewise the market trend of ever smaller production lot sizes per order.

RotaSpray GmbH will continue to be managed as an independent unit within the WEKO Holding Group and will focus purely on the high-quality textile sector.
WEKO has been developing and producing non-contact application systems for product optimization and surface finishing with different types of liquids and powdery substances since 1953. The areas of application are broad and the nonwovens, paper, tissue, printing, wood fiber boards, foils and metal industries are successfully supported with WEKO solutions.
