Long-lived lamellas for reinforcing buildings

Carbon fiber-reinforced polymer lamellas are an innovative method of reinforcing buildings. There are still many unanswered questions regarding their recycling, however. A research project by Empa's Mechanical Systems Engineering lab is now set to provide answers. Thanks to the support from a foundation, the project could now be launched.

The construction sector is responsible for around 60 percent of Switzerland's annual waste. The industry's efforts to recycle demolition materials are steadily increasing. Nevertheless, there are still end-of-life materials that, for the time being, cannot be reused as recycling would be too time-consuming and expensive. One of these are carbon fiber-reinforced polymer (CFRP) lamellas.

The construction sector is responsible for around 60 percent of Switzerland's annual waste. The industry's efforts to recycle demolition materials are steadily increasing. Nevertheless, there are still end-of-life materials that, for the time being, cannot be reused as recycling would be too time-consuming and expensive. One of these are carbon fiber-reinforced polymer (CFRP) lamellas.

Making buildings "live" longer
The reinforcing method developed by Urs Meier, former Empa Director at Dübendorf, has been used in infrastructure construction for 30 years. CFRP lamellas are attached with epoxy adhesive to bridges, parking garages, building walls and ceilings made of concrete or masonry. As a result, the structures can be used for 20 to 30 years longer. The method is increasingly being applied worldwide – mainly because it massively improves the earthquake resistance of masonry buildings.

"By significantly extending the lifespan of buildings and infrastructure, CFRP lamellas make an important contribution to increasing sustainability in the construction sector. However, we need to find a way how we can further use CFRP lamellas after the buildings are being demolished," explains Giovanni Terrasi, Head of the Mechanical Systems Engineering lab at Empa. To achieve this, he wants to develop a method for recycling CFRP lamellas. Convinced by this idea, a foundation supported it with a generous donation. The project officially launched in October.

Gentle separation
First, a mechanical process will be developed to detach the CFRP lamellas from the concrete without damaging them. Initial tests at Empa are encouraging: After the lamellas were separated from the concrete, they still had a strength of 95 percent – even if they had already been used for 30 years.

Then, the demolished CFRP lamellas shall be used to produce reinforcement for prefabricated components. Terrasi's goal: saving thousands of tons of CFRP lamellas from ending up in landfills after the demolition of old concrete structures and reuse them in low-CO2 concrete elements. After completion of the project, Giovanni Terrasi and his team – consisting of Zafeirios Triantafyllidis, Valentin Ott, Mateusz Wyrzykowski and Daniel Völki – want to produce railroad sleepers from recycled concrete, which will be reinforced and prestressed with demolition CFRP lamellas. This would give the "waste-to-be" material a second life in Swiss infrastructure construction.

Plastic snowfall in the Alps - New Empa Study about nanoplastic in the environment

In a new study, Empa researcher Dominik Brunner, together with colleagues from Utrecht University and the Austrian Central Institute for Meteorology and Geophysics, is investigating how much plastic is trickling down on us from the atmosphere. According to the study, some nanoplastics travel over 2000 kilometers through the air. According to the figures from the measurements about 43 trillion miniature plastic particles land in Switzerland every year. Researchers still disagree on the exact number. But according to estimates from the study, it could be as much as 3,000 tonnes of nanoplastics that cover Switzerland every year, from the remote Alps to the urban lowlands. These estimates are very high compared to other studies, and more research is needed to verify these numbers

The study is uncharted scientific territory because the spread of nanoplastics through the air is still largely unexplored.

But according to estimates from the study, it could be as much as 3,000 tonnes of nanoplastics that cover Switzerland every year, from the remote Alps to the urban lowlands. These estimates are very high compared to other studies, and more research is needed to verify these numbers

The study is uncharted scientific territory because the spread of nanoplastics through the air is still largely unexplored.

The scientists studied a small area at an altitude of 3106 meters at the top of the mountain "Hoher Sonnenblick" in the "Hohe Tauern" National Park in Austria.
Every day, and in all weather conditions, scientists removed a part of the top layer of snow around a marker at 8 AM and carefully stored it. Contamination of the samples by nanoplastics in the air or on the scientists' clothes was a particular challenge. In the laboratory, the researchers sometimes had to remain motionless when a colleague handled an open sample.

The origin of the tiny particles was traced with the help of European wind and weather data. The researchers could show that the greatest emission of nanoplastics into the atmosphere occurs in densely populated, urban areas. About 30% of the nanoplastic particles measured on the mountain top originate from a radius of 200 kilometers, mainly from cities. However, plastics from the world's oceans apparently also get into the air via the spray of the waves. Around 10% of the particles measured in the study were blown onto the mountain by wind and weather over 2000 kilometers – some of them from the Atlantic.

It is estimated that more than 8300 million tonnes of plastic have been produced worldwide to date, about 60% of which is now waste. This waste erodes through weathering effects and mechanical abrasion from macro- to micro- and nanoparticles. But discarded plastic is far from the only source. Everyday use of plastic products such as packaging and clothing releases nanoplastics. Particles in this size range are so light that their movement in the air can best be compared to gases.

Besides plastics, there are all kinds of other tiny particles. From Sahara sand to brake pads, the world is buzzing through the air as abrasion. It is as yet unclear whether this kind of air pollution poses a potential health threat to humans. Nanoparticles, unlike microparticles, do not just end up in the stomach. They are sucked deep into the lungs through respiration, where their size may allow them to cross the cell-blood barrier and enter the human bloodstream. Whether this is harmful or even dangerous, however, remains to be researched.

The third theme is EVERYDAY PLUSH. With “everyday plush” we want to imagine the desire to dress as if surrounded by a warm hug. In fact, this capsule includes Cashmere denim that ensure warm and soft feeling to the wearer; and “soapy-denim”, a fabric made with cotton and viscose that gives a soft and fluid hand. Moreover, cotton mixed with nylon gives the fabric a technical hand and an elegant image while maintaining stretch performance, lightness and softness.

The fourth theme is JAPAN CALLING. The rough touch-feel and the authentic aesthetic as the true Japanese denim are the main features of the fabrics belonging to this theme. The clients here can find high weight 100% cotton denim fabrics with authentic image and structured weave. To complete the capsule a special blend is available: fabrics with a Tencel slubby weft that gives soft and fluid touch together with a rough image.

Last but not least, the fifth theme: MOTHER NATURE. The container of all the most sustainable Berto fabrics, from Organic cotton fabrics GOTS certified, to Recycled cotton fabrics GRS certified, made regenerating their own production waste.

Linked with this last theme the company will present during BLUEZONE by MUNICH FABRIC START a special capsule collection of garments made with our PIANETA FABRIC, GRS certified and made with recycled cotton coming from their own waste of production. The same waste has been used by CADICA GROUP, an Italian premium trims maker, to do the SPECIAL LABELS and HANGTAGS of this capsule.

Recyclable fabric made with 60 % recycled fibres
The high-quality fabric components in the mask were developed by the innovative Rheintal-based company Schoeller Textil AG. The two-layer polyester fabric is hydrophilic (having an affinity to water) on the outside and hydrophobic (water-repelling) on the outside and furthermore features an antibacterial finish. Thanks to the cotton-like feel, the fabric offers pleasant wearing comfort. The sustainable fabric consists of 60 % recycled fibres. Within the framework of the wear2wear recycling cooperation (www.wear2wear.org), the masks can be recycled once again when they reach the end of their life cycle.

The reusable mask is made up by Forster Rohner AG in St. Gallen and in its European subsidiaries. It impresses with optimum fit and tested skin tolerance. All components of
the mask comply with the OEKO-TEX® Standard 100. The testing process screens for numerous controlled and non-controlled substances. Masks with the OEKO-TEX® Standard 100 label are safe to wear. Forster Rohner also added a fashion component to the technicallyinnovative mask. The subsidiary, Jakob Schlaepfer AG, created a special print for the mask of the kind otherwise only developed for famous couture and prêt-à-porter fashion labels around the world. In addition to white and plain-coloured masks, a limited edition of available print designs emerges, or specific colours or even individual print designs are created for major customers.

Sanitized® Odoractiv 10: Odor-free polyester functional clothing

  • Patented technology with bluesign®, ECO PASSPORT, and Skin Friendly certification

Polyester sport and functional textiles treated with Sanitized® Odoractiv 10 are protected against “permastink”. Already a holder of the Swiss Technology Award, the Sanitized® Odoractiv 10 odor-management technology can now carry the bluesign® sustainability label, the Skin Friendly certification from the Hohenstein Institute and the ECO PASSPORT by OEKO-TEX® label. SANITIZED AG has been a bluesign® system partner for over 10 years.

An unwelcome odor can quickly develop in polyester sport and functional clothing, even if freshly washed. This is “permastink”. It’s a challenge to the textile industry as it generally reduces the attractiveness and market opportunities of sport and functional clothing made from polyester.

An unwelcome odor can quickly develop in polyester sport and functional clothing, even if freshly washed. This is “permastink”. It’s a challenge to the textile industry as it generally reduces the attractiveness and market opportunities of sport and functional clothing made from polyester.

The patented, non-biocidal Sanitized® Odoractiv 10 technology provides specific solutions and sales arguments for the end products. It works in two ways: The odor-causing bacteria can’t stick to the textile surface and are washed out completely in a normal wash cycle. This is due to the anti-adhesive “coating” applied in the padding process. This effect has been proven in a test procedure developed in cooperation with EMPA (Swiss Federal Laboratories for Material Science and Technology). Secondly, the treatment has an adsorbing effect. The odors are “trapped” and repeatedly expelled during a normal wash cycle.

No binder, no nano
Another characteristic: The treatment with Sanitized® Odoractiv 10 doesn’t apply an additional binder system. As with all of our products, SANITZED AG uses no nano technology. The safety and tolerability have been confirmed by the Skin Friendly certification from the Hohenstein Institute and ECO PASSPORT by OEKO-TEX® label. These have now been joined by the bluesign® accreditation.

SEEK unites to trade with love.

A constantly evolving market and new global challenges ask for exciting concepts that unite the most forward-thinking players of the industry. For the show in January 2019, SEEK enters the next level with its TRADE UNION concept.
“At SEEK, we always look for new strategies to meet the demands of our valued buyers and brands”, explains SEEK Director Maren Wiebus. “Within that community spirit, TRADE UNION was created to enhance business opportunities for both sides. Moving away from a classic competitive model, SEEK’s TRADE UNION is about defining goals collaboratively – and achieving them together.”
 
SEEK’s 10th Anniversary marks an important moment not just for the event itself, but also for the TRADE UNION movement: with further development and relocation into the foyer of Arena Berlin, which highlights and strengthens this cooperative approach. Relevant buyers will be provided with special services and be able to reach an even more targeted brand audience what makes all parties benefit from this individual concept.

Relevant buyers will be provided with special services and be able to reach an even more targeted brand audience what makes all parties benefit from this individual concept.
With his distribution agency Haptiques Felix Engelmann supports the TRADE UNION idea from the beginning and emphasizes the time saving aspect: “The few days in Berlin are always very important for my company so that I aim to max the business days as much as possible. The SEEK team is very empathic about the market needs and already started talking about the new concept inside of SEEK several seasons ago. We are looking forward to work with our partners and colleagues in an extra space where we are able to value the time and make the life of buyers, press and brands easier.”

And Engelmann is not the only fan of this concept that Wiebus and team developed together with their long-term partners.
''The TRADE UNION is a fantastic concept aimed at giving brands with a true heritage an opportunity to sit together in one personal space. We feel that this will give our brands an opportunity to be shown in the best light possible, within a relaxed environment,” explains Joe Sharpe, Sales Director at Options. “We’re excited to be a part of the Trade Union and looking forward to seeing existing and potential clients in January.

Goodbye „Permastink“! Innovative odor-management for functional polyester textiles

Sanitized®Odoractiv 10 with patented, dual-action technology

SANITIZED AG presents a new unique dimension to odor-management for functional polyester textiles. The newly developed wash-resistant Sanitized®Odoractiv 10 has a dual-action effect: on the one hand it prevents the bacteria from docking on the textile, and on the other, it adsorbs odors whilst the garment is being worn. The underlying technology that has been further developed was awarded the Swiss Technology Award. Goodbye permastink!

Sanitized®Odoractiv 10 with patented, dual-action technology

SANITIZED AG presents a new unique dimension to odor-management for functional polyester textiles. The newly developed wash-resistant Sanitized®Odoractiv 10 has a dual-action effect: on the one hand it prevents the bacteria from docking on the textile, and on the other, it adsorbs odors whilst the garment is being worn. The underlying technology that has been further developed was awarded the Swiss Technology Award. Goodbye permastink!

Manufacturers of functional polyester textiles from all over the world face the same challenge: freshly washed garments develop an unpleasant odor even after a short wearing period. The cause of this undesirable effect is not the human perspiration itself, but the bacteria that break down the perspiration. This process of decomposition generates the characteristic sweet, pungent smell. Once the bacteria, or the odor molecules, have penetrated into the surface of the polyester textile, they remain there permanently. Machine wash cycles and special detergents will never completely eliminate them. The bacterial colonization produces a biofilm on the polyester, which not only causes unpleasant odors, but also has a negative impact on the properties of the material.

Surface modulation with anti-adhesive properties
This is exactly where the new, dual-action technology from SANITZED AG comes into play: the surface of the textile is "coated" with Sanitized®Odoractiv 10 in the padding process. This creates a protective film on the surface of the textile. The bacteria use this anti-adhesive protective film as the basis for latching onto the garment. The bacteria can therefore be completely washed out in a normal wash cycle, consequently preventing any biofilm from forming. An anti-adhesion test method was developed in cooperation with EMPA to prove this Wash Effect.

The second advantage: Sanitized®Odoractiv 10 has a high adsorbing effect. Odors are "trapped" and removed during a normal wash cycle. The new product is the result of a technology that has been further developed and was awarded the Swiss Technology Award. The odor adsorption is identified using GC-MS.

As the Product Manager at SANITIZED AG, Urs Zihlmann, succinctly puts it: "Sanitized®Odoractiv 10 marks the end of permastink in polyester textiles." Sanitized®Odoractiv 10 can be combined with other Sanitized®products, in particular with products based on zinc pyrithione. The treatment does not influence the feel of the final treated textile.

Wash-resistant, sustainable and still "no nano"
The odor-reducing function is clearly still going strong even after 50 wash cycles. This is even the case if garments are washed at 30°C, either by hand or in the machine, meaning consumers save on water and energy, not to mention that the piece of clothing will look great for longer.

As with all its other products, SANITZED AG does not use any nano technology. The Hohenstein Institute has awarded the company the rating Skin Friendly, the bluesign®registration is underway. The product also bears the label Eco Passport by OEKO-TEX®.

"The unique, dual Odor Control Function of Sanitized®Odoractiv 10 enjoys a unique position in the market and it furthermore fulfills two market requirements: the prevention of permastink and the minimization of odor intensity during wear. Almost all manufacturers of functional polyester textiles are confronted with this problem," commented Urs Zihlmann. "The new technology creates tangible added value for consumers. This is a competitive differentiating
advantage for global marketing."

As with all other products, the service provided by SANITIZED AG includes technological advice before and during production, in the definition of the verified efficacy and in the use of the Sanitized®Ingredient Brand for promotional purposes.
