From the Sector

Smart textiles have the potential to revolutionise healthcare. In his doctoral thesis in textile technology at the University of Borås, Emanuel Gunnarsson presents unique solutions to the bottleneck that has long inhibited the market.

With an ageing population, increasing demands are being placed on healthcare and smart textiles can offer a solution where only imagination sets limits. “The long-term goal of most smart textiles is for them to be so easy to use that the user doesn't think of them as anything more than regular garments. No special procedure should be needed to use them. If we succeed in that, we won't burden healthcare by having healthcare personnel administer vital parameter monitoring such as blood pressure and pulse, as the user can handle it themselves,” said Emanuel Gunnarsson.

In his work, he has investigated how a t-shirt for measuring heart rhythm and movement patterns, and garments for electrostimulation, can be produced in a single step. This involves the connection between the contact surfaces (electrodes), the insulated conductive paths between the electrode and the contact point, and the electrical measuring equipment required.

“This, as far as we know, has never been described before. We are completely convinced that this is the solution to a significant bottleneck when it comes to getting the smart textile market going in earnest,” said Emanuel Gunnarsson.

His work has resulted in two different simple ways to produce smart textiles. He demonstrates that sensors can be integrated using standard textile manufacturing methods. The research also includes criticism of some of the methods used to measure the functionality of smart textiles, and advice on how to do it better instead.

“The next natural step will be to see how these garments cope with one of the toughest challenges a garment faces, namely washing. Especially as these garments must be worn closest to the skin, they will need to be washed relatively often,” said Emanuel Gunnarsson.

Studies from other universities indicate that the yarns used to measure signals from the body do not withstand many washes, but after a small pilot study, Emanuel Gunnarsson is hopeful of the opposite.

Sappi is expanding its product range for corrugated board applications with Fusion Nature Plus.

With Fusion Nature Plus, Sappi is launching an uncoated, fully bleached and completely recyclable virgin fibre liner. The company provides a unique variety of packaging and speciality papers. The specialist in paper-based solutions also offers a wide range of products in relation to labels. Fusion Nature Plus offers excellent printing results in flexographic, digital and offset printing processes.

• Ultra-bright, uncoated virgin fibre paper with excellent printing results
• Ideal for attractive corrugated board as well as premium shopping bags
• Can be used as topliner, liner or fluting
• Available in grammages of 80 to 130 g/m²

The virgin fibre liner is based on the concept of the successful Fusion Topliner. In contrast to the double-coated Fusion Topliner, Fusion Nature Plus has a natural, uncoated surface with a more tactile feel, in response to the growing market appetite for this type of product. The liner is also provided in very low grammages.

Fusion Nature Plus enhances brand appearance

Brand owners, corrugated board processors, manufacturers of display cartons and folding cartons as well as designers all benefit from the versatility of the new Fusion Nature Plus. In contrast to conventional uncoated liner papers, the material offers high brightness, brilliant colour reproduction and consistently high quality. These features make the product the perfect choice for corrugated board or solid board packaging, where a very bright appearance is needed for topliners, inner liners and corrugating applications. Whether used as an inlay in cosmetics or confectionery packaging, or as a liner in shipping packaging to ensure an exceptional unboxing experience, Fusion Nature Plus is called upon wherever an enhanced appearance is desired.

Another area of application is paper carrier bags, where uncoated paper qualities are often preferred.

Fusion Nature Plus is ideally suited to a range of printing processes: the product achieves outstanding results in flexographic and offset printing. The pre-treated surface and high brightness offer clear advantages with regard to primer requirements and print behaviour, especially for inkjet-based digital printing. Bernd Gelder, Head of Sales Containerboard at Sappi Europe: ‘With its exceptional print quality and impressive colour reproduction, Fusion Nature Plus particularly appeals to packaging customers who value a natural look and feel in paper. The response from the market, in which packaging based on corrugated board still needs to take on a bigger role, is enormous, of course, with the result that we have succeeded in completing a number of interesting end applications and customer projects with Fusion Nature Plus shortly after market launch.’

Virgin fibre vital for recycling

In continuous recycling use, fiber that has already been recycled is subject to a progressive weakening of quality, resulting in a weakness in the products that incorporate them, but also, crucially, over time they will ultimately degrade to a point where they become unrecoverable. As a result, a certain amount of virgin fibre needs to be introduced into the cycle on a regular basis. Without continuous virgin fibre contribution to the pulp cycle, recycled producers will in the end run out of raw material. The premium virgin fibre liner Fusion Nature Plus from Sappi plays an important role here in maintaining the quality of the recycling substrate.

Thanks to the central location of Sappi’s production site in Ehingen, Fusion Nature Plus can be supplied quickly throughout Europe. The shorter transportation distances reduce transport related fossil emissions and protect the environment. The shorter production cycles in turn ensure high availability and rapid supply.

Fusion Nature Plus is currently available in six grammages from 80 to 130 g/m² in both sheet and roll form. Sappi can also provide Fusion Nature Plus with FSC or PEFC certificates on request.

Hologenix, creators of Celliant®, infrared responsive technology, and Kelheim Fibres, a world-leading manufacturer of viscose specialty fibers, have partnered to launch Celliant Viscose at ISPO Munich 2021. Celliant Viscose is a finalist in Best Products by ISPO and will be showcased in the Fibers & Insulations Category for ISPO Textrends, where realistic views and 3-D simulations will be available for each material.

The introduction of nature-based Celliant Viscose will be the first in-fiber infrared sustainable solution on the market and meets a consumer demand for more environmentally friendly textiles. An alternative to synthetic fibers and extremely versatile, Celliant Viscose blends beautifully with cotton, micromodal, lyocell, wool varieties including cashmere. It also has many applications across industries as it is ideal for performance wear, luxury loungewear, casual wear and bedding.

Celliant Viscose features natural, ethically sourced minerals embedded into plant-based fibers to create infrared products that capture and convert body heat into infrared, increasing local circulation and improved cellular oxygenation. This results in stronger performance, faster recovery and better sleep.

Celliant Viscose provides all the benefits of being a viscose fiber — lightweight, soft, highly breathable, excellent moisture management — as well as fiber enhancements from Celliant infrared technology. Celliant’s proprietary blend of natural minerals allows textiles to capture and convert body heat into full-spectrum infrared energy, resulting in stronger performance, faster recovery and better sleep. In addition, Celliant is durable and will not wash out, lasting the useful life of the product it powers.

An Affordable, Long-lasting Solution with Diverse Applications
As opposed to other IR viscose products which are coatings based, Celliant Viscose’s in-fiber solution increases wearability and longevity with a soft feel, durability from washing and longer life. The combination of Kelheim’s distinctive technology and the Celliant additives creates this unique fiber that provides full functionality without the need for any additional processing step — a new standard in the field of sustainable IR viscose fibers. This single processing also makes Celliant Viscose more cost-effective and time-efficient than coatings.

In addition, Kelheim’s flexible technology allows targeted interventions in the viscose fiber process. By modifying the fiber’s dimensions or cross sections or by incorporating additives into the fiber matrix, Kelheim can precisely define the fiber’s properties according to the specific needs of the end product.
