From the Sector

The European Union (EU) has upgraded the requirements for the Class 1 Medical Device designation and Hologenix®, creators of CELLIANT®, has met the stricter requirements for this important market. This means that compliant manufacturers can continue to use the CE mark on their EU products containing CELLIANT.

Brand partners simply need to comply with the requirements that Hologenix provides, and do not have to pursue regulations on their own. Regulatory status validates the science and technology behind CELLIANT, a natural blend of bioceramic minerals that absorb body heat and reflect it back as therapeutic infrared energy.

The list of products that are now registered in the EU as Class 1 Medical Devices has grown considerably since 2014 when Hologenix first sought registration and now includes bed blankets, bed sheets, duvets, duvet covers, mattresses, mattress covers, pillows, heat-reflective upper and lower torso garments, therapeutic diabetic socks, compression socks/stockings, support bandages, wraps and limb mobilization/support skin adhesive tape.  

The transition to the Medical Device Regulations in the EU for CELLIANT Class 1 medical devices includes more stringent requirements to demonstrate medical device safety for users, a refined quality management system and detailed technical documents.

Purecare, a wellness-focused bedding essentials manufacturer, has launched sheets and pillowcases with CELLIANT® Viscose, the first time the fiber has used been in luxury bedding products in a new offering aptly named the “Recovery Collection.”

Developed by materials science innovator Hologenix®, creators of CELLIANT, and Kelheim Fibres, CELLIANT Viscose is the first in-fiber sustainable infrared viscose. It is lightweighted, soft, highly breathable and has an excellent moisture management. CELLIANT has been clinically demonstrated to promote faster recovery and restful sleep, as it improves local circulation and cell oxygenation, enhancing thermoregulation and comfort.

The collection is available in five colors: dove gray, ivory, clay, moss, and sage in Queen through Split California King sizing and Queen and King pillowcases. The Precision-Fit® corners on the fitted sheets have a one-inch elastic cuff to ensure that they stay securely on the bed. The sheets are also compatible with adjustable base mattresses. The Recovery Collection sheets and pillowcases are also treated with Antimicrobial Silver Product Protection (AgCI).

Many people across the world are bedridden – be it due to illness, an accident or old age. Because those affected often cannot move or turn over by themselves, they often end up with very painful bedsores. In the future, it should be possible to avoid bedsores with the help of materials that can be programmed to entirely adapt their form and mechanical properties. For example, the body support of mattresses made from programmable materials can be adjusted in any given area at the push of a button. Furthermore, the support layer is formed in such a way that strong pressure on one point can be distributed across a wider area. Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Materials and microstructuring
Materials for applications requiring specific changes to stiffness or shape are being developed by researchers from Fraunhofer CPM, which is formed of six core institutes with the aim of designing and producing programmable materials. So, how can we program materials? “Essentially, there are two key areas where adjustments can be made: the base material – thermoplastic polymers in the case of mattresses and metallic alloys for other applications, including shape memory alloys – and, more specifically, the microstructure,” explains Dr. Heiko Andrä, spokesperson on the topic at the Fraunhofer Institute for Industrial Mathematics ITWM, one of the Fraunhofer CPM core institutes. “The microstructure of these metamaterials is made up of unit cells that consist of structural elements such as small beams and thin shells.” While the size of each unit cell and its structural elements in conventional cellular materials, like foams, vary randomly, the cells in the programmable materials are also variable – but can be precisely defined, i.e., programmed. This programming can be made, for example, in such a way that pressure on a particular position will result in specific changes at other regions of the mattress, i.e., increase the size of the contact surface and provide optimal support to certain areas of the body.

Materials can also react to temperature or humidity
The change in shape that the material should exhibit and the stimuli to which it reacts - mechanical stress, heat, moisture or even an electric or magnetic field - can be determined by the choice of material and its microstructure.

The journey to application
A single piece of material can take the place of entire systems of sensors, regulators and actuators. The goal of Fraunhofer CPM is to reduce the complexity of systems by integrating their functionalities into the material and reducing material diversity. We always have industrial products in mind when developing the programmable materials. As such, we take mass production processes and material fatigue into account, among other things,” says Franziska Wenz, deputy spokesperson on the topic at the Fraunhofer Institute for Mechanics of Materials IWM, another core institute of Fraunhofer CPM. The initial pilot projects with industry partners are also already underway. The research team expects that initially, programmable materials will act as replacements for components in existing systems or be used in special applications such as medical mattresses, comfortable chairs, variable damping shoe soles and protective clothing. “Gradually, the proportion of programmable materials used will increase,” says Andrä. Ultimately, they can be used everywhere – from medicine and sporting goods to soft robotics and even space research.

• Recypur successfully starts up a complete airlay line delivered by ANDRITZ for its mill in L’Alcúdia, Spain

The airlay line is designed for recycling of post-industrial and post-consumer foam and was developed specifically for the bedding and furniture industry, with material heights reaching 20 cm and densities of up to 120 kg/m3. Experimental tests carried out together with experts from ANDRITZ Laroche led to the conclusion that the mechanical method for recycling polyurethane is the most versatile and reliable.

With a capacity of 1.2 t/h, this airlay line enables Recypur to supply new mattresses made of industrial & post-consumer foam waste from old mattresses. This well proven process allows to reduce the environmental impact, increase self-sufficiency and eventually reduce the use of polyurethane. Such a set-up also allows multiple functional materials to be incorporated into the blend, such as flame-retardant, conductive and insulating fibers, among others. Thanks to this tailored approach, Recypur is now able to expand its diversification, innovation and reputation on the Spanish market.

The scope of supply includes a blending line with five feeders, an Exel 1500 for fine opening, an Airlay Flexiloft+ with 2.20 m working width, a recycling machine and an oven.

Airlay lines strongly support the circular economy and are part of ANDRITZ’s comprehensive product portfolio of sustainable solutions that help customers achieve their own sustainability goals in terms of climate and environmental protection.

Recypur, based in the Spanish province of Valencia, is part of DELAX, a Spanish group specialized in manufacturing and commercialization of innovative beds and mattresses. This company is the first Spanish manufacturer of recycled flexible polyurethane foam cores from post-consumer foam waste.

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.”

ANDRITZ will be presenting its innovative solutions for nonwovens production and textile manufacturing at INLEGMASH 2022 in Moscow, Russia, from March 14 to 17.

AIRLAY TECHNOLOGY
Protecting the environment and conserving natural resources require new technologies. In the textile-related industries, the current challenge is to develop industrially and economically viable solutions to use eco-friendly fibers in nonwovens. ANDRITZ focuses on the airlay nonwoven application for hemp fibers (used in mattress production, insulation, ...) and also geotextile end uses.

TEXTILE RECYCLING TECHNOLOGIES
ANDRITZ Laroche is a leading supplier of fiber processing technologies such as opening, blending, and dosing, airlay web forming, textile waste recycling, and decortication of bast fibers. One focus of this product range lies on complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end uses. ANDRITZ will present recycling technologies for end-of-life textile products that can be used in multiple applications, such as automotive, insulation, mattresses, and furniture felts.

Customer awareness and regulations are pushing apparel brands to recycle their textile waste and use the recycled textile fibers in their own products. To support ANDRITZ customers, a team with process know-how is available to conduct customized trials in our advanced technical center located at the ANDRITZ Laroche facilities in Cours, France.

BAST FIBERS
For the demanding Russian market for technologies based on bast fibers, ANDRITZ will present innovative products and the valorization of bast fibers, in particular hemp.
ANDRITZ Laroche is a player in the textile waste recycling sector, with airlay nonwoven technologies but also bast fiber decortication and cottonizing lines.

These eco-friendly fibers are used to spin yarn mixed with cotton, saving cotton as raw material, which reduces the consumption of water, pesticides applied in its cultivation and chemicals used during the dyeing and finishing processes.

Alchemie Technology, a leader in waterless, digital on-demand, smart dyeing technology, has today announced its partnership with HeiQ, a leader in textile innovation, as it prepares the production rollout of its NOVARATM digital multifunction finishing solution to the global textile market in Q3 this year.

NOVARA can apply single-sided, or simultaneous two-sided, coating of multiple finishes to specific areas of textile. For example, combining anti-odour and water repellence in one material.

“For example, using NOVARA for single-sided finishing of HeiQ Viroblock required 52% less chemistry, 66% water reduction and 50% less energy, whilst achieving a 99.7% reduction in antimicrobial activity after 15 washes at 400celsius. With the huge demand for high-performance antibacterial, antiviral finishing for face masks, medical apparel, gym wear, home furnishing, mattresses, and textiles for high-risk, high traffic areas such as train, plane seats, and more, our combined technology is critical for increasing protection and reducing environmental impact of these products” says Dr Simon Kew, Managing Director, Alchemie Technology.

NOVARA also enables unique lifestyle product innovations at lower production cost for fashion, sportswear, technical clothing, and upholstery such as combining sustainable odour control, skin care additives, and fragrance finishing, without impacting breathability, hand feel or wicking. It is suitable for finishing all fabric types, from 50 - 1000 gsm, including polyester, cotton, nylon and polycotton.

• Antiviral properties of Sanitized® products on synthetics validated

Tests conducted by independent laboratories have now confirmed that a treatment with Sanitized® T 99-19 and Sanitized® T 11-15 reduces the viral load on PES textiles by
up to 99 %.

Swiss company SANITIZED AG announces the validation from impartial labs that Sanitized®T 99-19 and Sanitized®T 11-15 are also effective against viruses (in accordance with ISO 18184:2019). Tests were performed using a feline coronavirus with structures and mechanisms reminiscent of SARS-Cov2. Patented technology featuring an ammonium silicate compound  is employed in Sanitized®T 99-19 and Sanitized®T 11-15 utilizes tried and tested silver technology.

These additives are the perfect tool for an antiviral and antibacterial treatment of face masks, protective professional medical clothing, bed linens, or mattresses. The formulation of both products remains completely untouched, thus ensuring that it will continue to offer outstanding protection against bacteria.

Before a final product’s antiviral properties can be publicly promoted, viral tests must be performed in specialized laboratories. Compliance with local legal regulations is essential here. SANITIZED AG explicitly points out that this is standard procedure and has composed a preliminary Guide for Treating PPE (personal protective equipment) with biocide products.

Textile innovator Devan Chemicals will launch two new technologies at the upcoming Techtextil show in Frankfurt (May 14-17). Bio-flam, a bio-based flame retardant product and Odour Breakdown, a wash durable, non-biocidal odour control solution.
As tradition goes, every two years Devan participates in Techtextil, the leading international trade fair for technical textiles and nonwovens. In the quest for sustainability and transparency every company faces these days, the new Devan technologies offer answers to product developers and portfolio designers.

Bio-flam
Some facts & figures: There are at least 5000 fire incidents each day in the EU. Yearly, about 70 000 people are hospitalised with fire-related injuries. Fires cause pollution. So sustainable fire performance of products is an economic, environmental and human necessity. Take the example of mattresses: tests indicate that when on fire, non-FR treated products give less than 5 minutes escape time. Unfortunately, that is not enough time for the fire brigade to arrive. Needless to say that to increase escape time, to reduce the risk and to save lives, products need to be flame retardant. The challenge is to obtain flame retardant properties in the most natural way, to find the right balance between safety for the people and for the planet.

Companies can do this by replacing raw materials from a non-renewable source, by bio-based FR treatments, which are made from renewable sources and do not contain halogens or heavy metals, as described in the norm EN 16785 1:2015. Bio-based FR treatments, like Bio-flam, are made from renewable, vegetable sources and enable the FR treated products to be biodegradable. The active components are 100% halogen- and heavy metal-free. A welcome innovation for the bedding industry, as the European Commission requires mattresses to be recyclable by 2030 in order to reduce landfill.

Bio-flam P307 is the first introduction in the new Devan BIO-FR family, and is biodegradable and is developed to be used on 100% cotton or cotton/viscose mixtures, in order to create an ecological concept, safe for people and planet, whatever might happen. Bio-flam P 307 is developed for mattress ticking to pass EN 597 1&2. The Devan researchers are developing other bio-based products for other market segments and for other fire standards.
