From the Sector

• Excellent project to encourage ingenuity among young students
• Experiment on biodegradability of textiles and nonwovens produces impressive results
• EUR 30,000 in prize money for a total of 209 participating schools in and outside Austria
• Lenzing views supporting these kinds of projects as part of its sustainability mission

Lenzing – The Association of Chemistry Teachers in Austria – known by its German abbreviation, VCÖ – has been holding project competitions that thrill students and take them beyond the traditional syllabus for 30 years. Every two years, it highlights a key topic for ninth- and tenth-graders to explore by conducting special experiments and learning from their observations and conclusions.

This year, the 16th installment of the competition is called, “Achieving a cleaner climate and a circular economy with chemistry”. These topics are also near and dear to the heart of globally active fiber manufacturer Lenzing. That’s why the company promptly announced that it was prepared to support this project competition in several different ways. First, Lenzing made a contribution toward the sponsorship fund totaling EUR 30,000. Second, it initiated a special prize on biodegradability – a topic of growing importance given the huge challenges involved in reducing plastic waste. Finally, Lenzing placed a recognized expert at the students’ disposal to provide assistance and answer questions: Michaela Kogler, Project Manager Nonwovens & Technical Products.

Teaming up with rainworms

Two teams were tasked with biodegrading different fibers – just like those used to produce textiles and nonwovens – with the active participation of worms. Students at BRG solarCity in Linz buried fiber nonwovens, a basic material used in wet wipes and other products, in soil that was populated with numerous rainworms, while students at Vöcklabruck Junior High School for Sports and Integration layered textiles into a vermicomposting bin. Both experiments intended to determine the extent to which certain materials would biodegrade quickly. As it turned out, both projects showed that wood-based fibers, like those that Lenzing manufactures for the textile and nonwoven industry, break down very rapidly into natural constituents that swiftly pass into the soil. In contrast, fossil-based plastics such as polyester or polyethylene cannot be decomposed by worms or bacteria but remain in the soil, sometimes for hundreds of years.

The prizes for this year’s competition were awarded on June 11. The competition attracted entries from no fewer than 209 schools, including 11 from outside Austria. For more information on the projects and the winners, visit www.vcoe.or.at.

• ANDRITZ receives an additional order for a high-speed spunlace line from Zhejiang Kingsafe, China

International technology Group ANDRITZ has received an order from Zhejiang Kingsafe Hygiene Materials Technology Co., Ltd. in Hezhou, China, to supply a complete new neXline spunlace line. The line is scheduled for installation and start-up during the second quarter of 2022.

This high-capacity spunlace eXcelle line will process either 100% biodegradable fibers or blends of polyester and viscose. It is dedicated to the production of hygiene and medical fabrics. The final products will have fabric weights ranging from 30 to 100 gsm, and the annual production capacity will be up to 18,000 tons.

ANDRITZ will deliver a complete line, from web forming to drying, also integrating two high-speed TT cards, the well-known JetlaceEssentiel hydroentanglement unit and the neXdry through-air dryer equipped with a neXecodry S1 system for energy saving. This combination is becoming the market benchmark for the production of lightweight spunlace fabrics dedicated to the hygiene market.

“We are proud to operate ANDRITZ nonwoven lines, which are very reliable and efficient. It helps us a lot in producing top-of-the-range, nonwoven roll goods, thus enabling us to be recognized as a key player among nonwovens producers worldwide,” says Kingsafe’s president, Mr. Huarong Yan.

Zhejiang Kingsafe Hygiene Materials Technology Co., Ltd., founded in 1987, is one of the largest companies in China producing spunlace and spunbond nonwoven roll goods, with several spunlace lines already in operation. The final products are exported all over the world and used in many fields, such as the medical sector, health care, high-tech agriculture, and high-quality consumer and household products.

The new line is now the ninth spunlace line supplied by ANDRITZ and the third with high-speed TT cards, thus confirming the successful, long-term partnership between ANDRITZ and Zhejiang Kingsafe. The order also proves that the solution provided by ANDRITZ is recognized as the benchmark for production of premium spunlace roll goods and contains the perfect combination for wipes converting machines.
