From the Sector

The diabetic community has always been a priority for Hologenix, creators of CELLIANT® infrared technology, so the company embarked on an initial study to test the hypothesis that the technology can positively impact diabetic patients with vascular impairment, now published in Journal of Textile Science & Engineering. Another study is underway as well with more research on the horizon.

According to statistics cited in the International Diabetes Federation Diabetes Atlas, 9th edition, globally, close to a half billion people are living with diabetes and that number is expected to increase by more than 50 percent in the next 25 years.
 
The introduction of the study in the Journal of Textile Science & Engineering also reports that diabetic patients frequently suffer from a combination of peripheral neuropathy and peripheral artery disease, which particularly affects their feet. It further states that it has been estimated that the lifetime risk for the development of foot ulcers in diabetic patients can be as high as 25 percent and that the risk of amputation is 10 to 20 times higher than in non-diabetic subjects.
 
The study was performed by Lawrence A. Lavery, D.P.M., M.P.H., a Professor in the Department of Plastic Surgery at UT Southwestern Medical Center. His clinic and research interests involve diabetic foot complications, infections and wound healing, and he participated in the conception, design, implementation and authorship of the Journal of Textile Science & Engineering study.  

CELLIANT technology is a patented process for adding micron-sized thermo-responsive mineral particles to fibers, in this case polyethylene terephthalate (PET) fibers. The resulting CELLIANT yarns were woven into stockings and gloves containing either 82% CELLIANT polyester, 13% nylon and 5% spandex or for the placebo, 82% polyester with no CELLIANT, 13% nylon and 5% spandex. CELLIANT products absorb body heat and re-emit the energy back to the body as infrared energy, which is non-invasive and increases temporary blood flow and cell oxygenation levels in the body.

The objective of the study was to “evaluate changes in transcutaneous oxygen (TcPO2) and peripheral blood flow (laser Doppler, LD) in the hands and feet of diabetic patients with vascular impairment when CELLIANT gloves and stockings are worn.” While there was not a statistically significant result across all subjects, the study did show that some patients wearing CELLIANT stockings for 60 minutes had an increase of as much as 20% in tissue oxygenation and 30% in localized blood flow. According to the study’s conclusion, “the trends that were observed in favor of CELLIANT stockings suggest that a larger well-designed clinical trial should be undertaken and may provide evidence of clinical efficacy in treatment of the diabetic foot.”
 
The study also notes that “There have been no documented or observed side effects of wearing CELLIANT stockings, and they are relatively inexpensive compared to conventional pharmaceutical interventions.”

Hologenix has embarked on a more comprehensive trial, “Study to Evaluate CELLIANT Diabetic Medical Socks to Increase Tissue Oxygenation and Incidence of Complete Wound Closure in Diabetic Foot Wounds” – NCT04709419, which focuses on the impact of CELLIANT technology to potentially improve tissue oxygenation and wound healing outcomes.
 
“We are excited to explore whether future studies of infrared, with its most common biological effects of increased localized blood flow and cellular oxygenation, could result in a breakthrough in diabetic patients with vascular impairment,” said Seth Casden, Hologenix Co-founder and CEO. “We see a huge potential opportunity with this research for helping to fulfill our core mission of improving people’s health and well-being by potentially reducing the impact of diabetes, and we are actively seeking partners to expand our research efforts.”

SABIC will present its portfolio of PURECARES™ and TRUCIRCLE™ materials for the healthcare and hygiene market at INDEX™23 from April 18 to 21 in Geneva, Switzerland, under the theme of ‘Collaborating for sustainability and innovative solutions’.

At INDEX, SABIC will highlight a joint project with two market leaders, using certified circular polymers from the TRUCIRCLE portfolio in recyclable films for feminine hygiene, baby care and disposable medical applications. In all of these cases from diapers to surgical drapes and medical gowns, the sustainable materials can serve as direct drop-in alternatives with no compromise in production efficiency and product performance.

Further examples on display at the company’s booth will feature TRUCIRCLE solutions for facemasks, including an N95 design that localizes the value chain with SABIC® PURECARES PP spunbond and meltblown polymers in Saudi Arabia. SABIC provides complete solutions for facemask production as part of its localization strategy and has been a key enabler of the Saudi Made initiative. Also shown will be a closed-loop facemask developed in collaboration with industrial and research partners in Europe.

The company’s PURECARES polyolefin products are based on technologies free of both tris (nonylphenyl) phosphite (TNPP) and phthalates. Consumer comfort is achieved by using SABIC polypropylene (PP) and polyethylene (PE) polymers for bi-component fibers to answer multiple needs for soft and loft handfeel nonwovens, enabling easy lamination to other building blocks on medical nonwovens or absorbent hygiene applications.

In addition, SABIC produces TRUCIRCLE certified circular polymers for its PURECARES PP and PE portfolio with feedstock based on advanced recycling of mixed and used plastic that would otherwise typically not be suitable for mechanical recycling processes. These more sustainable solutions can be adopted in downstream processes as direct drop-in alternatives to incumbent materials with no compromise in production efficiency, purity and product performance.

Carbios announces the publication of an article entitled “Enzymes’ power for plastics degradation” in Chemical Reviews.

RadiciGroup presented Biofeel® Eleven, a yarn of natural origin, at the Performance Days trade fair (from March 15-16 in Munich). Biofeel® Eleven is sourced from castor oil and is suitable for obtaining bio-polymer. It can be used for fabrics and fine garments in many sectors, from fashion to sports, from automotive to home textiles.

Today, 80% of the world's castor-oil plantations are in India, particularly in the Gujarat region, due to its favourable climatic conditions. In this area, local people can earn an additional income by cultivating semi-arid land that does not compete with food production, and by applying the skills they have acquired over time to this work. Over the years, thanks to research, development and innovation in the value chain, the seeds from which the oil is produced have been selected and certified to ensure the finest quality, also in terms of end uses.

Castor beans contain around 45% oil, rich in ricinolein, from which the bio-polymer polyamide 11 is derived. This is the polymer RadiciGroup uses for its Biofeel® Eleven yarn. What remains after the first pressing is a highly effective bio-fertiliser that is returned to the soil.

Biofeel® Eleven can also be solution dyed, i.e. dyed at the yarn production stage, saving a great deal of water and energy and also providing greater colour stability.

The Institut für Textiltechnik (ITA) of RWTH Aachen University, as part of the Mittelstandzentrum 4.0 Kompetenzzentrum Textil vernetzt, has supported numerous small and medium-sized enterprises (SMEs) on their way to digitalisation over the last five years. At the Digital Capability Center (DCC) in Aachen, for example, SMEs were able to experience digitised production from yarn to smart bracelets and thus test the feasibility of Industry 4.0 solutions in their working environment.

New supply chain laws and social sustainability now pose current challenges for SMEs. In the follow-up project Mittelstand-Digital Zentrum Smarte Kreisläufe (SME Digital Centre Smart Cycles), ITA will be supporting SMEs from 1 March in implementing ideas for digitalisation and sustainability in concrete terms.

This means finding sustainable solutions and processes for the circular economy together with companies and developing new digital business models. The ITA's solutions cover the areas of awareness-raising, qualification, implementation and networking. These offers are free of charge for SMEs - follow-up projects often lead to the funding programme "Central Innovation Programme for SMEs - ZIM" of the Federal Ministry of Economics and Climate Protection (BMWK) or to research and development projects.

• Technical innovation and natural fibres, for a broader definition of sustainability

The weaving collection further develops the themes that have emerged in recent seasons, interpreting them with a view to long-term sustainability.

In harmony with the Südwolle Group’s identity and values, research and technical innovation are combined with a high level of quality. Wools, almost all certified, are enriched by a significant level of performance that continues to evolve. The production process attempts to limit carbon footprint, as sustainability is the key principle guiding all the company’s choices.

The ability to offer yarns made from selected natural raw materials is in harmony with today’s sustainable buying habits, with a preference for garments and accessories that can be worn at any time of year. In contrast with the logic of fast fashion, today’s buyers, led by younger generations with a focus on the values behind their fashion choices, tend to choose items that can be expected to last longer, decreasing the environmental impact of textile wastes and throwaway fashion.

In casual wear too, the importance of comfort and feeling at ease is reconciled with the desire to wear items of good taste and quality. The new formalwear includes carefully cut garments made of materials guaranteeing fit, comfort and durability. A widespread focus on these factors makes for more conscientious, reasoned purchases, less subject to impulse buying.

Südwolle interprets the new interest in heritage, leading to the emergence of the phenomenon of quality second-hand, with a return to its core business and essentials, in a new sustainable version using certified fibres, chlorine-free anti-shrinkage treatments and long-lasting products that can be washed at home at low temperatures.

One of the most recent results of the company’s technical innovation is the new OTW® line of yarns for weaving produced using Omega Twist® technology, developed and patented by the Südwolle Group, producing yarns offering outstanding performance in terms of reduced pilling and greater elasticity, tenacity and durability.

• Iconic 200 Series fleece to be the first fabric made from this new process.

Polartec®, a Milliken & Company brand, announces Polartec® Shed Less Fleece, a new milestone in its industry-leading efforts to reduce textile fiber fragment shedding. Shed Less is a process that combines yarn construction, knitting, chemistry, and manufacturing to reduce home laundry fiber fragment shedding by an average of 85%. The first fabric to receive this new technology is the brand’s iconic Polartec® 200 Series Fleece, the modern version of the original PolarFleece® launched in 1981, and in 1993, the first performance fleece knit from yarn made from recycled plastic bottles.

The Shed Less process works by engineering the lofted fibers that give fleece its soft hand the ability to resist breaking and rubbing off during home laundering, cited as one contributing factor to the spread of fibers fragments (commonly referred to as microfibers). Polartec® Shed Less Fleece achieves this while maintaining all of the attributes that continue to make Polartec fleece a staple of midlayer collections - lightweight, breathable and warm.

The brand used the AATCC (American Association of Textile Chemists and Colorists) TM212-2021 test method for fiber fragment release during home laundering. This test was conducted with large sample sizes to account for variability. The testing concluded that Shed Less Fleece reduced fiber fragment shedding by an average of 85% compared to the baseline fabric.

“In 2016 we began looking into how we might test for fiber loss because there wasn’t a lot of research on the issue.” said Aimee LaValley, Polartec Textile Development, Dye and Chemistry Manager. “This led to new products like Polartec Power Air™, new manufacturing processes, as well as our participation in the TextileMission workgroup to study the issue on an interdisciplinary basis.”

TextileMission was a three year collaborative initiative of academia and industry to reduce the impact of textile microplastics funded by the German Federal Ministry of Education and Research. Founding partners include The Association of the German Sporting Goods Industry, Hochschule Niederrhein - University of Applied Science; TU Dresden - Institute of Water Chemistry; Vaude Sport; WWF Germany; Adidas AG; Henkel AG; Miele & CIE; and Polartec, LLC.

Polartec® Shed Less Fleece will be initially launched in the United States and will be available to customers beginning March 1, 2023. The brand plans to apply the Shed Less process to many other industry-leading fabric platforms and manufacturing facilities around the world.

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.
