From the Sector

Recently, OETI awarded the OEKO-TEX® STeP certification to two companies in the sector of personal protective equipment (PPE) and workwear: Ötscher - Berufskleidung Götzl GmbH, Austrian producer and wholesaler and longstanding PPE and OEKO-TEX® STANDARD 100 customer, and ALSICO MOROCCO (Cindico), a Moroccan PPE and work wear producer and part of the global Alsico Group, which has already introduced the certification for production facilities in Belgium and Laos.

OEKO-TEX® STeP stands for Sustainable Textile and Leather Production and is a certification system for production facilities in the textile and leather industry. The STeP system analyses critical areas of businesses using six modules: Chemical Management, Environmental Performance, Environmental Management, Social Responsibility, Quality Management, and Health protection and Safety at work.

For ALSICO MOROCCO (Cindico), OEKO-TEX® STeP offers the benefit of "a unified certification system and standardised audits to monitor social and ecological responsibility processes at global production locations," says Managing Director Mary Meylaers.

For the Austrian company Ötscher – Berufskleidung (workwear), Managing Director Thiemo Götzl emphasises the strengths of the certification in transparent communication with customers and stakeholders and a comprehensive overview of all aspects of the supply chain. "The certification also supports compliance with the German Supply Chain Due Diligence Act requirements through transparency and risk mitigation," says Thiemo Götzl.

Together with the German circular knitting machine builder Mayer & Cie., Groz-Beckert has developed the optimized Relanit sinker SNK F over the past years. Independently of this, the development of the new LCmax™ energy-saving needles took place. The focus of both developments is on efficiency, energy savings and increased process reliability.

Groz-Beckert offers interested machine builders different cooperation options to jointly develop new products or optimize existing ones. The Groz-Beckert Technology and Development Center (TEZ) provides the appropriate framework for so-called co-development projects. At the ITMA in Milan in June 2023, Groz-Beckert presented some of the successful cooperations under the motto "Innovation through cooperation". Among them were two new developments realized with Mayer & Cie. Groz-Beckert presented the two new products for the first time in Asia at ITMA Asia in November 2023.

Optimized Relanit sinker SNK F
At the end of 2018, circular knitting machine manufacturer Mayer & Cie. approached Groz-Beckert with a request to jointly develop an improved and more efficient sinker for selected machines of their Relanit family that would run more smoothly and reliably in the needle tricks. The innovative sinker has an integral spring with a spring force that is adapted to the sinker thickness. Field tests were consistently successful and confirmed the functionality and advantages of the new sinker.

Thanks to their adapted spring, the newly developed SNK F Relanit sinkers are securely guided while they are running through the cam track, resulting in a quieter operation. This increases process reliability and ensures an improved loop structure. In addition, wear on the swivel butts of the sinkers is reduced. This increases service life and makes the process more sustainable and cost-efficient.

Higher energy efficiency thanks to LCmax™
The objective second recent cooperation with Mayer & Cie. was to develop a cost-effective energy-saving needle. After considering various variants, the common choice of Mayer & Cie. and Groz-Beckert was the LCmax™ knitting machine needle with innovative, wave-shaped shank geometry. The first prototypes were extensively tested on laboratory machines at Groz-Beckert's TEZ.

The wave-shaped shank of the LCmax™ needle ensures a smaller contact area of the needle in the needle trick. This results in less friction, which reduces machine temperature and enables energy savings of up to 20 percent compared to a standard needle. This saves costs and at the same time allows operation of the machine at the maximum possible speed.

In both projects, the cooperation between Mayer & Cie. and Groz-Beckert went far beyond mere product development. In addition to Applications Engineering and Construction, the companies' Sales and Purchasing departments were also involved in a close exchange.

After four decades in the packaging industry, the Manjushree Group is entering the Indian nonwovens market. The entrepreneurs rely on a flexible RF Smart Composite line from Reifenhäuser Reicofil to meet very different customer requirements.

The Manjushree Group operated a blown film line for packaging materials for the tea industry in the eastern part of India as early as 1983. In the years that followed, Manjushree Technopack Ltd. developed into one of the largest suppliers of solutions for rigid plastic products in South Asia - and the family business grew into a group with several business segments. In 2018, the entrepreneurial family repositioned itself: it sold its previous core business to a financial investor and established Manjushree Ventures with footholds in start-up financing, real estate business, and manufacturing - the largest of which is Manjushree Spntek as a producer of high-quality spunmelted fabrics.

Since February 2023, Manjushree Spntek has been producing high-performance spunmelts on an RF Smart Composite line from Reifenhäuser Reicofil - benefiting both from many years of experience in the packaging industry and from experience with Reifenhäuser's blown film lines. "We know a lot about plastic extrusion, for example when it comes to line operating parameters such as temperature and pressure. Processing is similar in both industries," explains Rajat Kedia. "The main difference is the distribution of the products: In plastic packaging, we had an established customer base and sold a lot of material to the big consumer goods manufacturers. The nonwovens market in India, on the other hand, is still forming, with thousands of small companies currently getting involved." These serve customers in their regions, such as hospitals.

The RF Smart Composite line is a standardized spunmelt line for smaller and emerging markets. The line produces nonwovens of the highest Reicofil quality with appropriately adapted throughput. This makes it ideally suited for applications in hygiene and medical technology and, with typically 8,200 annual production hours, it is extremely reliable. In addition, operators can start production quickly because in many cases the line can be integrated into existing buildings.

Before production could start, Manjushree built a new production building in Bidadi, a town an hour's drive from Bangalore International Airport. The building is designed to be sustainable: It uses natural light and fresh air, has comprehensive contamination control, and obtains almost all of its energy from renewable sources. Reifenhäuser Reicofil then installed, commissioned and tested the RF Smart Composite line.

Since February 2023, Manjushree Spntek has been producing high-quality spunmelted nonwovens, including ultra-soft fabrics and fabrics with special coatings for customers in the hygiene and medical industries. The material can be used, for example, for baby diapers and feminine hygiene products, but also for medical articles ranging from surgical gowns to surgical drapes.

The Lenzing Group has received certification from the internationally recognized EU Ecolabel for its fibers at the Indonesian site. This means that Lenzing fibers produced in Purwakarta (PT. South Pacific Viscose) meet high environmental standards. The product portfolio thus expands and qualifies for the production of LENZING™ ECOVERO™ brand fibers for textiles and VEOCEL™ brand fibers for nonwoven applications.

The substantial investment of EUR 100 mn to modernize the Indonesian site has enabled Lenzing to significantly reduce its specific emissions. In addition, the site recently began sourcing energy from renewable sources and is driving the conversion to biomass in line with Lenzing's goals of reducing group-wide carbon emissions per ton of product sold by 50 percent by 2030 and achieving carbon-neutral production by 2050.

Anthropogenic climate change is one of the most pressing problems of our time, to which both the global textile and nonwovens industries make a major contribution. LENZING™ ECOVERO™ viscose fibers (for textiles) and VEOCEL™ Viscose (for nonwovens) have been proven to cause significantly less greenhouse gas emissions and water pollution than conventional viscose. At the Indonesian site, Lenzing also plans to produce the innovative LENZING™ ECOVERO™ Black fibers in the future, which also require less energy and water in textile chain thanks to the spun-dyeing process and thus also have a lower carbon footprint in their life cycle as a textile product.
