Rudolf: DWR trough replica of natural models
The durable water repellent (DWR) finishes Ruco-Dry Bio CGR and Ruco-Dry Bio NPE are made from natural waste that accumulate as by-product during the processing of cereal grains in the food industry. They upcycle and give new life and purpose to by-products and waste of the food industry. These 2 breakthrough products do not compete with human and/or animal nutrition and they are marketed through the Bio-Logic brand by the producer of textile auxiliaries Rudolf GmbH, Geretsried/Germany, that captures the emerging trend of performance rooted in bio-carbon.
Biomimicry and studies of natural models such as lotus leaves or feathers played an important role in redefining the environmental impact of some textile chemistry.
Ruco-Dry Bio NPE is the first durable water-repellent finish entirely based on a selected mix of natural plant extracts. The well-balanced mix of plant-based ingredients combines excellent water and stain repellent effects with breathability and natural handle.
By turning natural waste into DWR, Rudolf has optimized the biologic character of Ruco-Dry Bio CGR where the active component is made of more than 90% bio carbon. It delivers breathability and good fabric touch and meets the performance and durability standards applied to water repellent textile finishes.

Johns Manville: 1st phase of plant expansion in Ohio completed
End of 2020 phase 1 of fiberglass pipe plant expansion of the producer of nonwovens and glass fibers Johns Manville Corp. (JM), Denver, CO/USA, at their production plant in Defiance, OH/USA, has been completed.
The expansion added the 1st of 2 new production lines, improving JM’s ability to meet demand for Micro-Lok HP and Micro-Lok HP Ultra fiberglass pipe insulation, which is used primarily in commercial buildings.
The JM team in Defiance employed a wearable computer called a HoloLens that rests on the head and acts as a see-through screen where images may be displayed for the wearer to reference while still being able to see through the screen into the real world. The helmet takes high-definition footage of the objects in front of the wearer and displays that footage through Microsoft Teams at a remote location.
In this case, the footage was displayed in real-time in Germany, where many of the engineers who worked on the project are based. This technology helped bridge the distance between the engineers in Germany and the team in the USA so the expansion could be finished even during the corona pandemic.
Freudenberg: Eco-Check for sustainable products
The Eco-Check label helps customers to quickly and clearly find sustainable products. The producer of technical textiles Freudenberg Performance Materials Holding SE & Co. KG, Weinheim/Germany, has now begun using the Eco-Check label to identify particularly sustainable products within its portfolio.
Eco-Check label meet demanding criteria in at least one of 4 categories: saving resources, eco-efficiency for customers, reduced environmental impact at the end of the product’s life, or extended durability.
Many of Freudenberg’s products bearing the Eco-Check label contain a high proportion of recycled polyethylene terephthalate (PET), derived for example from plastic bottles. In this case, the most important environmental advantage is the reduction in CO2 emissions.

Kelheim Fibres: EMAS certification for environmental commitment
The manufacturer of viscose specialty fibers Kelheim Fibres GmbH, Kelheim/Germany, has become the 1st viscose fiber manufacturer worldwide to receive the “Eco Management and Audit Scheme” (EMAS) certification. This is a standardized eco-management certification system developed by the European Union.
EMAS includes the globally applicable ISO 14001 standard and goes beyond its requirements by demanding more transparency and continuous improvement. Certified companies report in their annual EMAS Environmental Statement on their environmental goals and their progress in meeting them.
In contrast to the EU Ecolabel and similar certifications, EMAS does not apply to individual products or services, but certifies the complete environmental performance of the company. This benefits not only the protection of the environment and climate, but also the improvement of a company’s eco-efficiency.
PyroTex: reduction of influenza virus by 99%
A recent test conducted on the PyroTex medic fiber from the fiber manufacturer PyroTex Fibers GmbH, Hamburg/Germany, has confirmed an activity of 99.99% against the Human Influenza A virus H3N2. Furthermore, the fiber also hinders the viruses SARS-CoV-2and MS2, as well as the bacteria Staphylococcus Aureus, Eschericha Coli and Klebsiella Pneumoniae.
PyroTex medic fiber is used in protective masks, general protective and medical clothing, and for the hospitality and private sector.
The properties do not have to be reactivated, remain indefinitely and are non-toxic (certified to Oeko-Tex Standard 100, Class I).
Empa: color change as an indicator of damaged ropes
Safety ropes used by fire brigades or suspension ropes for heavy loads on construction sites can lose their mechanical properties undetected when exposed to high temperatures, friction or fire.
A research team from the Swiss Federal Laboratories for Materials Science and Technology, Empa, Dübendorf/Switzerland, and the ETH Zurich, Switzerland, have now developed a coating that changes color due to their physical reaction to heat thus clearly indicating whether a rope will continue to provide the safety it promises in the future.
3 layers are required to ensure that the fiber actually changes color when heated. The researchers applied silver to the fiber itself, in this case polyester and Vectran (high-tech fiber spun from a liquid-crystal polymer). This serves as a reflector - in other words, as a metallic base layer.
This is followed by an intermediate layer of titanium nitrogen oxide, which ensures that the silver remains stable. Finally, there follows the amorphous Germanium-antimony tellurium (GST) layer, which is just 20 nm thick, that causes the color change. When this layer is exposed to elevated temperatures, it crystallizes, changing the color from blue to white. Depending on the chemical composition of the temperature-sensitive layer, this color change can be adjusted to a temperature range between 100 and 400 °C and thus adapted to the mechanical properties of the fiber type.
ECRA: European carpet and rug industry reveals circular economy action plan
The European Commission’s Circular Economy Action Plan 2.0 will accelerate the transition from a linear to a circular economy and constitutes an essential shift to a low-carbon industry. The European carpet and rug industry supports this transition and presents realistic objectives and adequate measures in its strategy paper from the European Carpet and Rug Association (ECRA), Brussels/Belgium, titled “Leading the carpet industry towards circular economy: a 2030 strategic approach”.
The industry has the potential to play a leading role in achieving Europe’s ambitions for a climate-neutral and circular economy but believes that this can only be achieved if it is fully supported by a well-functioning EU regulatory framework with adequate funding and financial incentives.
In its strategy paper, the industry presents innovation as the driver of change, making new technologies and circular materials permanent features of the future, and increasing sustainable and renewable products in the market adhering to the principles of circularity.
The industry approach relies on a fully integrated, multi-dimensional and cross-sectorial value chain enabling industry-wide initiatives to be implemented. The active participation of all stakeholders is required to make these initiatives successful. It is vital to consider the entire life cycle of the products from inception and design for ‘end-of-life’, through to manufacturing and consumption. The industry therefore encourages the better management of scarce resources and continues to focus on the creation of material pools, proactively prohibit the use of substances of high concern, target zero waste to landfill initiatives and support the recycling of plastics.

Karl Mayer: Stoll brand demonstrates strength in China
In China, the current infection development allows face-to-face events again. Around 380 visitors took advantage of the opportunity to meet on site at the first presentation of the Stoll brand as a segment of the Karl Mayer Group, Obertshausen/Germany. The in-house show took place in Changzhou/China from December 17-19, 2020.
The Stoll brand will continue to operate independently as part of Karl Mayer with the same contacts as the previous manufacturer of flat knitting machines H. Stoll AG & Co. KG, but with the support of the Karl Mayer group of companies.
A highlight of the machine show in Changzhou was the topic of knit & wear. In the seamless knitting of sweaters, eliminating almost all downstream finishing processes, Stoll is setting standards in terms of patterning possibilities and price/performance, as demonstrated by the ADF 830-24 ki W knit & wear and CMS 830 ki knit & wear.
The CMS 830 ki knit & wear with the new gauge E 10.2 will allow customers to participate in the market of fine knit & wear articles.
An innovation for the creative process was presented with the new Connective Pattern Software Stoll-CPS. The solution combines a full-featured, advanced programming system with an easy-to-learn user interface and significantly expands knitting possibilities.
