From the Sector

The announcement of a new effluent treatment plant (ETP) marks a milestone in Denim Expert's journey towards sustainability. This upcoming facility is a testament to the company's dedication to reducing its ecological footprint and safeguarding local ecosystems through advanced water management techniques.

The new Effluent Treatment Plant (ETP) being developed by Denim Expert strives for 100% wastewater recycling. As the ETP rises from concept to reality, Denim Expert embarks on a transition towards its next horizon: aligning with the Zero Discharge of Hazardous Chemicals (ZDHC) Wastewater Guidelines Version 2.0.

Denim Expert's proactive approach to sustainability has been recognized on a global scale. The company has been named 'New Champion' by the World Economic Forum and has partnered with organizations such as the Sustainable Apparel Coalition (SAC), the United Nations Framework Convention on Climate Change (UNFCCC), and the Ellen MacArthur Foundation's Jeans Redesign program. As one of the first factories to join the Partnership for Cleaner Textile (PaCT) and in the process of implementing the 3E program, Denim Expert is dedicated to achieving 100% water reuse and full reliance on solar energy, further solidifying its commitment to driving positive environmental change.

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Depending on humidity and temperature, natural fiber materials can degrade in the soil in a matter of months or even a few days. In order to significantly extend the degradation time and make them suitable for geotextiles, the Denkendorf team researches a protective coating. This coating, based on lignin, is itself biodegradable and does not generate microplastics in the soil. Lignin is indeed biodegradable, but this degradation takes a very long time in nature.

Together with cellulose, Lignin forms the building materials for wood and is the "glue" in wood that holds this composite material together. In paper production, usually only the cellulose is used, so lignin is produced in large quantities as a waste material. So-called kraft lignin remains as a fusible material. Textile production can deal well with thermoplastic materials. All in all, this is a good prerequisite for taking a closer look at lignin as a protective coating for geotextiles.

Lignin is brittle by nature. Therefore, it is necessary to blend the kraft lignin with softer biomaterials. These new biopolymer compounds of brittle kraft lignin and softer biopolymers were applied to yarns and textile surfaces in the research project via adapted coating systems. For this purpose, for example, cotton yarns were coated with lignin at different application rates and evaluated. Biodegradation testing was carried out using soil burial tests both in a climatic chamber with temperature and humidity defined precisely according to the standard and outdoors under real environmental conditions. With positive results: the service life of textiles made of natural fibers can be extended by many factors with a lignin coating: The thicker the protective coating, the longer the protection lasts. In the outdoor tests, the lignin coating was still completely intact even after about 160 days of burial.

Textile materials coated with lignin enable sustainable applications. For example, they have an adjustable and sufficiently long service life for certain geotextile applications. In addition, they are still biodegradable and can replace previously used synthetic materials in some applications, such as revegetation of trench and stream banks.

Thus, lignin-coated textiles have the potential to significantly reduce the carbon footprint: They reduce dependence on petroleum-based products and avoid the formation of microplastics in the soil.

Further research is needed to establish lignin, which was previously a waste material, as a new valuable material in industrial manufacturing processes in the textile industry.

The research work was supported by the Baden-Württemberg Ministry of Food, Rural Areas and Consumer Protection as part of the Baden-Württemberg State Strategy for a Sustainable Bioeconomy.

Intertextile Shanghai Home Textiles – Spring Edition is set for a renewal.

Other presentations and discussions that touch on sustainability will also be available under the fair’s Textile & Technology event theme.

With consumers globally paying more attention to health issues and increasing their spending on health products, the home and contract textile industry is also a party to this rising trend. To this end, seminars discussing traditional Chinese medicine and how it relates to different health issues will be held on day one. Their crossover topics include how aromatherapy can encourage high-quality sleep, as well as an introduction on the innovation of traditional medicinal textiles.

Moreover, the well-known Chinese retailer JD.com will co-host an event that promotes home textile products made with Chinese cotton. Several talks will focus on different aspects, such as the products’ quality and the overall potential of this industry aided by government policies.

After China’s relaxation of border restrictions and other pandemic control measures, it is now easier for domestic and overseas buyers to visit their Chinese suppliers at the fairground, for the chance to touch and feel their desired products.

For the third time, nova-Institute awards the “Cellulose Fibre Innovation of the Year” award in the frame of the “Cellulose Fibres Conference 2023” (8-9 March 2023). The conference advisory board nominated six remarkable products, including cellulose fibres from textile waste, banana production waste and bacterial pulp, a novel technology for producing lyocell yarns and a hygiene product. The innovations will be put to the vote of the conference audience on the first day of the event, with the awards ceremony taking place in the evening. The innovation award “Cellulose Fibre Innovation of the Year 2023” is sponsored by GIG Karasek (AT).

Here are the six nominees
Vybrana – The new generation banana fibre – GenCrest Bioproducts (India)
Vybrana is a Gencrest’s Sustainable Cellulosic Fibre upcycled from agrowaste. Raw fibres are extracted from the Banana Pseudo stem at the end of the plant lifecycle. The biomass waste is then treated by the Gencrest patented Fiberzyme technology. Here, cocktail enzyme formulations remove the high lignin content and other impurities and help fibre fibrillation. The company's proprietary cottonisation process provides fine, spinnable cellulose staple fibres suitable for blending with other staple fibres and can be spun on any conventional spinning systems giving yarns sustainable apparel. Vybrana is produced without the use of heavy chemicals and minimized water consumption and in a waste-free process where balance biomass is converted to bio stimulants Agrosatva and Bio Fertilizers & organic manure.

HeiQ AeoniQ™ – technology for more sustainability of textiles – HeiQ (Austria)
HeiQ AeoniQ™ is the disruptive technology and key initiative from HeiQ with the potential to change the sustainability of textiles. It is the first climate-positive continuous cellulose filament yarn, made in a proprietary manufacturing process and the first to reproduce the properties of polyester and nylon yarns in a cellulosic, biodegradable, and endlessly recyclable fibre.
HeiQ AeoniQ™ can be manufactured from different cellulosic raw materials such as pre- and post-consumer textile waste, biotech cellulose, and non-valorized agricultural waste, such as ground coffee waste or banana peels. It naturally degrades after only 12 weeks in the soil. Each ton of HeiQ AeoniQ™ saves 5 tons of CO2 emissions. The first garments made with this innovative cellulosic filament fiber were commercially launched in January 2023.

TENCEL™ LUXE – lyocell filament yarn – Lenzing (Austria)
TENCEL™ LUXE is LENZING’s new versatile lyocell yarn that offers an urgently needed sustainable filament solution for the textile and fashion industry. A possible botanical alternative for silk, long-staple cotton, and petrol-based synthetic filaments, is derived from wood grown in renewable, sustainably managed forests, and produced in an environmentally sound, closed-loop process that recycles water and reuses more than 99 % of organic solvent. Certified by The Vegan Society, it is suitable for a wide range of applications and fabric developments, from finer high fashion propositions to denim constructions, seamless and activewear innovations, and even agricultural and technical solutions.

Nullarbor™ – Nanollose & Birla Cellulose (Australia/India)
In 2020, Nanollose & Birla Cellulose started a journey to develop and commercialize tree-free lyocell from bacterial cellulose, called Nullarbor™. The name derives from the Latin “nulla arbor” which means “no trees”. Initial lab research at both ends led to a joint patent application with the patent “production of high-tenacity lyocell fibres made from bacterial cellulose”.
Nullarbor is significantly stronger than lyocell made from wood-based pulp; even adding small amounts of bacterial cellulose to wood pulp increases the fibre toughness. In 2022, the first pilot batch of 260kg was produced with 20 % bacterial pulp share. Several high-quality fabrics and garments were produced with this fibre. The collaboration between Nanollose & Birla Cellulose now focuses on increasing the production scale and amount of bacterial pulp in the fibre.

Circulose® – makes fashion circular – Renewcell (Sweden)
Circulose® made by Renewcell is a branded dissolving pulp made from 100 % textile waste, like worn-out clothes and production scraps. It provides a unique material for fashion that is 100 % recycled, recyclable, biodegradable, and of virgin-equivalent quality. It is used by fibre producers to make staple fibre or filaments like viscose, lyocell, modal, acetate or other types of man-made cellulosic fibres. In 2022, Renewcell, opened the world’s first textile-to-textile chemical recycling plant in Sundsvall, Sweden – Renewcell 1. The plant will eventually reach 120,000 tons of annual capacity.

Sparkle sustainable sanitary pads – Sparkle Innovations (United States)
Globally, around 300 billion period products are discarded every year, resulting in millions of tons of non-biodegradable waste. Since most conventional sanitary pads contain up to 90 % plastics, they do not biodegrade for around 600 years. Sparkle has designed sustainable, plastic-free, biodegradable and compostable Sparkle sanitary pads. From product to packaging, they are made up of around 90 % cellulose-based materials with top sheet, absorbent core, release paper, wrapping paper and packaging made of cellulose-based fibres. Whether Sparkle pads end up in a compost pit, are incinerated or end up in a landfill, they are a more sustainable alternative compared to conventional pads that contain large amounts of plastics, complex petro-chemical based ingredients and artificial fragrances. When tested according to ISO 14855-1 by a leading independent lab in Europe, Sparkle pads reached over 90 % absolute biodegradation within 90 days in commercial composting conditions.

Hologenix’s CELLIANT® infrared technology, an ingredient in textiles across many categories including bedding, is now offered in a new line of sustainable dog beds. The first performance fabric product from AVANTI, RESPOND is a wellness collection that promotes good health not only for pets but also for the planet. It is made from 100% recycled PET and uses patented CELLIANT technology for unmatched performance.

CELLIANT transforms the body’s heat into full-spectrum infrared energy. This energy is reflected back to the body, making it possible for the tissue and muscle to absorb it, promoting local circulation and tissue oxygenation. This technology helps keep the body dry and at the appropriate temperature. CELLIANT has been demonstrated to enhance energy, endurance, strength, stamina and comfort as well as promote faster recovery and more restful sleep. The RESPOND beds’ orthopedic memory foam filler adds an extra layer of comfort and wellness.

Introduced at Interzoo in Germany in May, RESPOND dog bedding was the result of determination by AVANTI leaders Raghav and Devika Modi to become champions of pet wellness and performance products while also aligning with the New Delhi, India-based company’s focus on sustainability.  

Ideal for ailing and senior pets, RESPOND beds are made from GRS-certified 100% recycled polyester CELLIANT yarns and orthopedic memory foam and have natural latex-coated bases for extra skid-resistance. AVANTI pet bed covers are removable and washable.

RESPOND dog beds are offered in nine SKUs, three different shapes and three colorways of each shape: grey, blue/grey and green/grey in shades that are associated with wellness.

At the forthcoming Texprocess, Techtextil and Heimtextil shows taking place in Frankfurt from June 21-24 – members of the Swedish Textile Machinery Association TMAS will be showcasing a range of solutions aligning with the growing trend for more localised and automated textile manufacturing.

Digitalisation and the push for more sustainable, shorter and less expensive supply chains are currently making manufacturing in high-cost countries within Europe more attractive and there have been many other contributing factors to this over the past two years.

The Covid-19 pandemic exposed the vulnerability of many countries to shortages of essential items like PPE while at the same time making the full exploitation of new digital options essential during national lock-downs and long periods of restricted travel. The escalating cost of global transportation, as well as the growth of online retailing and the associated benefits of on-demand digital manufacturing, are further reinforcing the many benefits of short-run and near-shore new operations.

Secure supply
At Texprocess, for example, Eton Systems will be unveiling its latest Ingenious software solution which further enhances the company’s Opta Unit Production System (UPS) introduced in 2021.

“Our automated technology has already had a great impact on the productivity of thousands of garment production lines,” says Eton’s Managing Director Jerker Krabbe. “Our systems help producers across the world to reduce repetitive manual tasks and increase efficiency, which evens out some of the differences between production in high and low-cost countries, making reshoring a feasible option. Creating a diversified production portfolio with a mix of production facilities, some closer to home, makes for a more secure product supply.”

Flexibility
Imogo meanwhile recently installed the first industrial scale dyeing system in Sweden for many years. The Dye-Max spray dyeing line has the potential to slash the use of fresh water, wastewater, energy and chemicals by as much as 90% compared to conventional jet dyeing systems. It is capable of carrying out the application of a wide range of fabric pre-treatments and finishing processes, providing users with unbeatable flexibility in production.

“Here in Scandinavia, we are currently seeing an explosion of companies developing sustainable new cellulosic fibres – many from waste clothing – but a problem is that all of the environmental benefits they deliver can potentially be lost in the further processing, and especially in conventional dyeing,” observes the company’s Founding Partner Per Stenflo. “The Dye-Max system positively addresses this, but interest in it has not just been confined to Europe. We are currently seeing a lot of activity in Turkey – largely as a near-shore partner to European brands – but also in Bangladesh.”

Robotics at Heimtextil
ACG Kinna Automatic specialises in automation solutions for filled products such as quilts, pillows and mattresses and its live demonstrations of robotics in action have proved a magnet for visitors to Heimtextil. This year’s show will be no exception.

“The use of robotics is now standard across many industries dealing in solid goods, but the handling of soft materials such as textiles is a little more complex,” says Managing Director Christian Moore. “Nevertheless, it’s something we have successfully mastered, and our robotic systems are proving highly beneficial to their users. There is no ‘one-size-fits-all’ solution when it comes to automation and our approach is always to carefully examine where it will make the difference in each bespoke system. A focus is on identifying and eliminating bottlenecks which will increase product flows.”

During the Covid-19 pandemic, ACG Kinna drew on all of its automation know-how and extensive network of contacts to build a new nonwovens fabric converting and single-use garment making-up plant in a matter of weeks, in order to supply the Swedish authorities with urgently-needed medical gowns.

Instant colour
Localised textile production is also booming in the USA, where Coloreel has recently secured multiple orders for its instant thread colouration technology via its US partner Hirsch.

“Coloreel technology enables the high-quality and instant colouring of a textile thread while it is actually being used in production and can be paired with any existing embroidery machine without modification, while also making it possible to produce gradients in an embroidery for the first time,” explains VP of Sales Sven Öquist.

“Advanced rapid colour formulation software and high-speed drive technology allow a single needle to carry out what it previously required many multiples of them to do – and with much more consistent stitch quality. By instantly colouring a recycled white base thread during production, our system enables complete freedom to create unique embroideries without any limitations. Colour changes along the thread can either be made rapidly from one solid colour to another, or gradually, to make smooth transitions or any colouring effect desired. This provides big benefits when it comes to sustainability and design creativity.”

Milestone
Svegea will be promoting its latest EC 300 collarette cutting machine at Texprocess 2022. This machine is used by garment manufacturers around the world for the production of tubular apparel components such as waistbands, cuff and neck tapes and other seam reinforcements. With its E-Drive 2 system and fully automatic FA500 roll slitter, the EC 300 has an output of around 20,000 metres per hour.

“Advances in automation are only making the specialised, bespoke machines we engineer even more efficient and we are expecting a very busy year,” says Managing Director Håkan Steene. “The garment components our collarette cutters produce make it logical for them to be integrated into the operations of making-up operations, wherever they are.”

Sensors
The advanced yarn tension monitoring technologies of Eltex of Sweden meanwhile play an essential role in rectifying defects in  weaving, tufting and composite reinforcement operations.

“A correct tension of the warp and weft threads ensures proper machine operation,” explains Eltex Global Marketing and Sales Manager Anoop K. Sharma “The constant tension monitoring and automatic control of the tension of the thread help to overcome unnecessary problems.

“We continue to make advances in both the hardware and software of our tension monitoring systems, such as the EyE™ for the warping process. With the EyE™, the yarn tension values from all yarns are continuously updated and displayed on screen. In addition, tension values outside the warning level are indicated both on the sensor’s LEDs and on the screen for complete quality control. No fabric can be woven without the appropriate and correct tension.”

Stahl, an active proponent of responsible chemistry, today announces that – by the end of Q2 2022 – it will extend its GHG reduction targets to cover Scope 3 emissions. This step underlines Stahl’s commitment to aligning its strategy with the 2015 Paris Climate Agreement goals, updated at the recent COP26 in Glasgow.

Between 2015 and 2020 Stahl reduced its Scope 1 and 2 (direct) GHG emissions by 37%, and has committed to a further 2% reduction each year to 2030. Scope 3 emissions cover all the indirect emissions that can occur in a company’s value chain, including raw material acquisition, transportation, and the end-of-life impact of its products. By focusing on Scope 3 emissions, Stahl is committing to de-fossilizing its supply chain and ensuring further accountability for its total environmental impact.

Michael Costello, Stahl Group ESG Director: “Only by focusing on reducing Scope 3 emissions can we accurately align our de-fossilization strategy with the global goal of limiting global average temperature increase to 1.5°C, as agreed at the 2015 Paris Climate Agreement and the COP26 in Glasgow. We look forward to working with partners across our industry and value chain to make this happen.”
