Researchers Produced Materials to Replace Plastic

Aalto University and VTT (Technical Research Centre of Finland) scientists have produced a new bio-based material by uniting wood cellulose fibres and the silk protein found in spider web threads.

The material – very firm and resilient – may be used in the future to replace plastic, as part of bio-based composites and in medical applications, surgical fibres, the textile industry and packaging.

Achieving strength and extensibility at the same time has so far been a great challenge in material engineering. Increasing strength has meant losing extensibility and vice versa. The new material overcomes this challenge.

According to Aalto University Professor Markus Linder, nature offers great ingredients for developing new materials, such as firm and easily available cellulose and tough and flexible silk as used in this research. The advantage with both of these materials is that, unlike plastic, they are biodegradable and do not damage nature the same way micro-plastics do.

“Our researchers just need to be able to reproduce the natural properties,” adds Linder, who led the research.

“We used birch tree pulp, broke it down to cellulose nanofibrils and aligned them into a stiff scaffold. At the same time, we infiltrated the cellulosic network with a soft and energy dissipating spider silk adhesive matrix,” said research scientist Pezhman Mohammadi from VTT.

Silk is a natural protein which is excreted by animals like silkworms and also found in spider web threads. The spider web silk used by Aalto University researchers, however, is not actually taken from spider webs but is instead produced by the researchers using bacteria with synthetic DNA.

“Because we know the structure of the DNA, we can copy it and use this to manufacture silk protein molecules which are chemically similar to those found in spider web threads. The DNA has all this information contained in it,” Linder explains.

“Our work illustrates the new and versatile possibilities for protein engineering. In the future, we could manufacture similar composites with slightly different building blocks and achieve a different set of characteristics for other applications. Currently, we are working on making new composite materials as implants, impact resistance objects and other products,” says Mohammadi.

The research project is part of the work of the Centre of Excellence in Molecular Engineering of Biosynthetic Hybrid Materials (HYBER). The research has been published in Science Advances.

The World’s First Fully Customisable and Zero-Waste 3D Printed Skirt

Fashion tech pioneer Julia Daviy has launched the world’s first zero-waste digitally customisable 3D-printed skirt.

A technology that allows zero-waste and cruelty-free clothing production becoming a reality with large-format professional 3D printing.

After ‘The Liberation Collection’ launched in 2018 at New York Fashion Week in 2018, Julia Daviy became obsessed with the idea of making 3D printed clothing commercially available, disrupting the idea of standardisation.

“It was critical to simplify digital customisation and 3D print wearable clothing with flexible materials. We’ve accomplished that, and I think that consumers will respond fast.”

“Our goal was never to demonstrate the viability of 3D printed clothin. We’ll have succeeded when beautiful, comfortable, ethically manufactured and environmentally friendly clothes are the standard” she added.

With a patented technology that uses 100 percent recyclable filaments, Julia and her team can meet the most exigent customer demands.

The team is being able not only to create highly customisable 3D printed garments according to consumers’ needs but also apparel of zero-waste for a cleaner and more sustainable world.

Production Phase          

Once the customers finalise their choice for a garment’s pattern, style, colour, waistline, and lining, Daviy and her team use the information to create a digital model of the garment.

Once modelled, the creation is approved by the client and sent to the 3D printers. The final product takes around ten days to complete.

First Devan R-Vital® Cbd-Infused Textiles Hit The Market

With the recent launch of Acabada ProActiveWear, the first CBD-infused textiles are officially hitting the market. The fabric treatment behind the CBD-infused textiles was developed by Devan Chemicals, a Belgian company specialized in functional finishes for the worldwide textile markets.

Devan launched its CBD (Cannabidiol) fabric treatment at Heimtextil 2019 in Frankfurt as part of their R-Vital® range of microencapsulated active ingredients. The range contains active substances like Aloe Vera, Q10, Vitamin E… with CBD being its latest addition. Now, only 8 months later, the first CBD-infused products are hitting the market.

High-quality organic CBD

Born in 2019, Acabada ProActiveWear is the world’s first and only CBD-infused activewear brand, committed to creating innovative, luxury apparel for the proactive woman. Conceptualized in New York and produced in Portugal, Acabada infuses luxury fabric with the highest quality organic CBD, to ensure that women will look, feel and perform at their best. Thanks to the close and intense cooperation between Acabada, Devan and the Portuguese production partner, goods were in store in less than five months starting from initial contact.

With over 30 years in the apparel industry, Acabada CEO and Co-Founder Seth Baum recognized the positive effects of CBD on pain and inflammation and the fact that top athletes embrace the active ingredient as a part of their training and recovery ritual. Baum assembled a team of experienced fashion designers, including Co-Founder and CCO Katrina Petrillo, and together they created a high fashion yet innovative product that is primed to disrupt the market. “While typical CBD products such as tinctures and edibles are growing exponentially in popularity, we began to envision a product that addressed health and wellness through a different lens. By physically infusing CBD into our garments, our product live at the intersection of fashion, fitness, and wellness,” says Baum. With Acabada ProActiveWear, recovery starts from the moment you get dressed by helping to fight soreness and promote healing before the first squat, lunge or crunch.

Each garment from Acabada ProActiveWear contains up to 25 grams of zero-THC, lab-certified, 99.9% pure CBD, which will allow the benefits to last through 40 high-intensity wear and wash cycles. As customers approach 40 wears and washes, they can choose to sustainably recycle their CBD-infused garments through Acabada’s upcycling program, where the recycled, synthetic fabrics will be repurposed where needed as commercial materials.

Microencapsulation

Through a scientific process called microencapsulation, CBD molecules are strategically infused into luxe, high-performance fabrics by wrapping microscopic droplets of zero-THC, hemp-derived CBD with a protective coating. Using Devan’s patented textile finishing treatment, the microcapsules bond to the fibres in the fabric. Strategically placed within the garments to align with muscle groups, the microcapsules gradually open over time as each layer meets with friction from your skin. When the individual capsules break open, the CBD is released and trans-dermally absorbed, where it interacts with your body’s endocannabinoid system (ECS) to help regulate and reduce pain and inflammation caused by physical activities. In the meantime, Devan has put together extensive research and testing documentation in order to accommodate questions from brands and retailers on this trendy subject.

Lenzing™ Fibers Help to Improve The Quality of Life for Butterfly Children

Undergarments, pajamas and bed linens tested for months. Moisture management of fibers reduce sweating and hence itching. Soft and smooth fibers lead to fewer skin injuries.  

The Lenzing Group, market leader for specialty fibers from the renewable raw material wood, has been providing both financial support and textiles made of its fibers to DEBRA Austria, the patient organization for “butterfly children.”

In recent months, several patients with the skin disorder Epidermolysis Bullosa (EB) have tested leggings, undergarments, pajamas, quilts and bed linens made of TENCEL™ fibers and have found them to be comfortable and skin-friendly. The skin of EB patients is fragile like the wings of a butterfly. For this reason, coarse fibers, scratching seams, buttons, zippers and fibers which hardly or do not at all absorb sweat frequently lead to additional blisters and sores and increased itching. In contrast, TENCEL™ fibers feature particularly good moisture management and thus support the nature temperature-regulating properties of the body.

“Lenzing™ fibers are characterized by their special softness and are thus pleasant for the ‘butterfly children’ to wear”, says Stefan Doboczky, Chief Executive Officer of the Lenzing Group. “We are proud that textiles made of our fibers are very positively received by young and older EB patients and that we are able to make an important contribution here to improving their quality of life. We make use of positive feedback to develop new products which are even softer and more comfortable.” he adds.

“I am pleased that the Lenzing Group is devoting its attention to further developing specialty fibers, which is an important topic for ‘butterfly children’. This is because pleasant and soft garments which support the nature temperature regulation of the skin and thus a cool and dry feeling contribute to a better quality of life for younger and older patients on a daily basis”, states Rainer Riedl, father of a “butterfly child” and Chairman and Managing Director of DEBRA Austria.

Epidermolysis Bullosa (EB) is a genetic disease which is currently incurable. The skin of affected people is particularly vulnerable due to the lack of structural proteins, like the wings of a butterfly. This condition is the origin of the name “butterfly children”. Thanks to its TENCEL™ fibers, the Lenzing Group has a product which stands out due to its particular softness and high moisture absorption and therefore offers outstanding wearing comfort. The cooperation of DEBRA Austria and the Lenzing Group as well as other partners such as the Ebensee Fashion School will be continued due to the positive feedback.

New Composite Advances Lignin As A Renewable 3D Printing Material

Scientists at the Department of Energy’s Oak Ridge National Laboratory have created a recipe for a renewable 3D printing feedstock that could spur a profitable new use for an intractable biorefinery byproduct: lignin.

The discovery, detailed in Science Advances, expands ORNL’s achievements in lowering the cost of bioproducts by creating novel uses for lignin—the material left over from the processing of biomass. Lignin gives plants rigidity and also makes biomass resistant to being broken down into useful products.“Finding new uses for lignin can improve the economics of the entire biorefining process,” said ORNL project lead Amit Naskar. Researchers combined a melt-stable hardwood lignin with conventional plastic, a low-melting nylon, and carbon fiber to create a composite with just the right characteristics for extrusion and weld strength between layers during the printing process, as well as excellent mechanical properties.

Lignin chars easily; unlike workhorse composites like acrylonitrile-butadiene-styrene (ABS) that are made of petroleum-based thermoplastics, lignin can only be heated to a certain temperature for softening and extrusion from a 3D-printing nozzle. Prolonged exposure to heat dramatically increases its viscosity—it becomes too thick to be extruded easily.

But when researchers combined lignin with nylon, they found a surprising result: the composite’s room temperature stiffness increased while its melt viscosity decreased. The lignin-nylon material had tensile strength similar to nylon alone and lower viscosity, in fact, than conventional ABS or high impact polystyrene.

The scientists conducted neutron scattering at the High Flux Isotope Reactor and used advanced microscopy at the Center for Nanophase Materials Science—both DOE Office of Science User Facilities at ORNL—to explore the composite’s molecular structure. They found that the combination of lignin and nylon “appeared to have almost a lubrication or plasticizing effect on the composite,” noted Naskar. “Structural characteristics of lignin are critical to enhance 3D printability of the materials,” said ORNL’s Ngoc Nguyen who collaborated on the project. Scientists were also able to mix in a higher percentage of lignin—40 to 50 percent by weight—a new achievement in the quest for a lignin-based printing material. ORNL scientists then added 4 to 16 percent carbon fiber into the mix. The new composite heats up more easily, flows faster for speedier printing, and results in a stronger product.

Ahlstrom-Munksjö Launches New Surgical Fabric

Ahlstrom-Munksjö, a leader in fibre-based materials, has announced the launch of its new ViroSēl fabric, constructed for the most critical areas of a surgical gown, designed to keep medical professionals protected and comfortable.

ViroS l is Ahlstrom-Munksjö’s next generation Breathable Viral Barrier (BVB) surgical fabric that has a specially formulated design that provides the opportunity to create robust seam seals for highly critical areas of a surgical gown, the company reports.

“We leveraged our BVB product development and manufacturing experience to create a fabric that can be reliably used in the most protective and comfortable surgical gowns on the market,” said Jason Beard, product platform leader, Medical, Ahlstrom-Munksjö. ViroS l is a tri-laminate fabric constructed to be impervious, breathable and comfortable. The outer layer is fluid repellent and durable. The barrier layer has a monolithic film membrane making it impervious to liquids, viruses and bacteria. The chemical composition of the film itself allows moisture vapor to pass through it, keeping the surgical staff cool and dry. Finally, the darker inner layer was designed to reduce shadowing, and is soft to the touch which makes it comfortable to wear for long periods of time.Surgeries like Cesarean sections, gastric and cardiac often have a substantial amount of fluids involved and are lengthy to complete. This means protection and comfort are essential for the medical professionals wearing the surgical gown. Infection control is imperative as there is risk to the patient and staff to potentially come into contact with these fluids. International in- dustry standards are used to test and measure the barrier performance for liquids and blood-borne pathogens for materials used in protective clothing like surgical gowns. ViroS l passes these stringent standards providing the impervious protection needed in the surgical environment, the manufacturer explains.

Filter Media for Air Pollution Control Applications

Ahlstrom-Munksjö also announced the launch of Ahlstrom-Munksjö Extia 1000, breakthrough, highly durable, filtration media designed to extend filtration lifetime for air pollution control applications,  helping to protect people and the environment. Extending filtration lifetime by more than 40%, helping customers to extend the operational duration, before needing to change the filters. “Giuseppe Costa, VP Product Development Filtration and Performance said “Due to its unique design, Extia 1000 dramatically extends filtration lifetime; it also delivers highly effective removal of coarse particles at over three times lower level of pressure drop.”

Ipeker Makes a Difference in Textile Products with Vegan Fabric Production

Ipeker company, founded in 1930, started its business life with the production of silk in Ottoman period at the end of the 1800s and then continued with fabric manufacturing. Ipeker, one of the most important companies of the world, started to use vegan fabrics produced with V-Label certificate in home textile.

Currently exporting to 52 countries, Ipeker has completed the testing process and produces vegan fabrics with the V-Label certificate given by the European Vegetarian Union. Using its experience in home textiles, the company is the pioneer of the world in this field. With offices in Germany, England and Italy, Ipeker serves with vegan and vegan cupro fabrics in a wide range of countries including Germany, France, Italy, America, Japan, Australia and Canada.

Ipeker, is the first and only manufacturer position in cupro fabric in Turkey, working hard on the production of vegan fabrics to produce more environmentally friendly fabrics. Ipeker Board Member İhsan Ipeker, who stated that there is no animal protein at any stage of the produced fabrics said; “This is guaranteed by DNA testing. Its are also stated as process in the Oeko-Tex certifications. We are the first company in the world to realize this. Our fabrics travel around the world with TR code. This is another source of pride for us.”

Vegan Cupro Fabric slow down the aging process

The vegan cupro fabric, which is produced from cotton wastes, is mixed into the soil within three months when it is buried. With this fabric, the company aims to protect the rights of life rather than using animals as a product. In addition, the company Ipeker argues that animals are not a property of people, even a piece of their bodies should not be used for the comfort of people. This fabric, which is sensitive to human skin, contains the least amount of detergent on it. It slows down permeating chemicals used in washing to human skin. It has climatic properties in terms of skin sensitivity. Thanks to its non-electrifying feature, it enables the body functions to work more smoothly.

In addition, Ipeker developed Vegan Sleep Technologies as a result of the work of its 35 people R & D team. The anti-aging pillows produced by the company eliminate the factors that accelerate aging, slow down this process as much as possible.
