Karl Mayer: new machine for grid warp knitted fabric in China

Specifically designed to produce light to medium-heavy grid structures, Karl Mayer Technische Textilien GmbH, Chemnitz/Germany, a segment of Karl Mayer Textilmaschinenfabrik GmbH, Obertshausen/Germany, has developed a new warp knitting machine with weft-insertion and thus further differentiated its range offer in this field.
The new model, the Wefttronic II G, handles technical yarn extremely gently. Geogrid fabrication is now 60% more productive compared to the previous version. In addition, less expensive yarns can be processed into high-quality textiles: the textile glass fiber material can cost up to 30% less than leno fabric production.
The first Wefttronic II G was ordered by the Polish manufacturer Halico Sp. Z.O.o., Pogwizdów Nowy, in early 2019, followed by orders from Shandong Qiyad Fiberglass Products Co., Ltd., Heze City, Shandong/China, and Zibo Glasstex Group Corp. (Shandong Fiberglass), Zibo, Shandong/China. After purchasing one machine each, they hinted that they may invest in further Wefttronic II G models.
Shandong Qiyad uses around 750 rapier looms in total for their production and thus offers efficiency potential. Depending on product quality, between 13 and 22 rapier looms can be replaced by just one Wefttronic II G.
Zibo Glasstex is a manufacturer of glass fibers, rovings and textiles. It is among the top 5 manufacturers of glass fibers in China and plans to invest in further machines. According to the company’s own information, it intends to work a market with an annual volume of 2 billion m² of textile glass fiber material and to achieve a significant market share.

ARTA: advantage to reusable in environmental footprint

A life cycle assessment (LCA) on behalf of the textile services industry has found that reusable surgical gowns provide a significant improvement in energy, environmental footprint, water, and energy-associated emissions. In asddition, reusable gowns offer an 83% reduction in waste stream.
The study commissioned by the American Reusable Textile Association (ARTA), Shawnee Mission, KS/USA, and the International Association for Healthcare Textile Management (IAHTM), Powell, OH/USA, was conducted by Environmental Clarity, Inc., Glen Allen, VA/USA, and compared the life cycle of reusable versus disposable surgical gowns.
The study found that choosing reusable isolation gowns instead of disposable alternatives decreases the environmental footprint by:
•    64% lower natural resource energy consumption,
•    66% lower greenhouse gas emissions,
•    87% lower total water consumed,
•    83% lower solid waste generation at healthcare facility.
The reusable and disposable gown systems were compared on a cradle-to-end-of-life basis. The starting point for analysis was natural resources in the earth, such as fossil materials and ores. The entire supply systems required to manufacture a final surgical gowns and packaging were included. The use phase included laundry and wastewater treatment for reusable gowns and sterilization for all gowns.

Centexbel: kick-off for new project on advanced composite manufacturing

Centexbel: kick-off for new project on advanced composite manufacturing Interreg Euregio Meuse-Rhine is a potential hot-spot for the further development of advanced material and process technologies. Technical Centers and Institutes around Aachen/Germany, Liège/Belgium and Eindhoven/The Netherlands were awarded with the new project AACOMA (Accelerate advanced composite manufacturing). Innovative material design and advanced manufacturing provide large opportunities for SMEs. The AACOMA project kick-off took place in Aachen at the Campus of the RWTH University of technology in Q1/2020. The aim of the project, which is running for 3 years until 2023 with a budget of €3 million, is to connect SMEs with innovation hot-spots like institutes and technical centers. 7 partners from all 3 regions will carry the project out: the textile research center Centexbel, Gent/Belgium, is the project leader and gets support by University of Liège, Sirris and Flanders Make from Belgium, as well as Fontys University of Applied Science and AMIBM of Maastrich University in the Netherlands and AMAC in Germany.

Oerlikon Nonwoven: 50 million protective masks made in Germany

From autumn 2020, up to 50 million masks of protection classes FFP1 to FFP3 will be produced and sold in Germany each month for the European market. The 2 newly founded companies FleeceforEurope GmbH, Düsseldorf/Germany, and Lindenpartner, ein Angebot der Bechinger & Heymann Holding GmbH, Berlin/Germany, primary will focus on quality. These virus-absorbing nonwovens will be manufactured by the new venture FleeceforEurope in Germany using an Oerlikon Nonwoven meltblown system of the technology group Oerlikon Management AG, Pfäffikon/Switzerland. With the masks, protection against infections such as corona virus can only be guaranteed with the right quality. On the one hand, this relates to how the masks are made. On the other hand, it is above all about what is inside. Because the nonwovens used in protection class FFP1 through FFP3 respiratory masks plays a decisive role. The electrostatic charging ensures that even the smallest particles, and therefore also viruses, are drawn in and absorbed by the nonwovens fabric for several hours. As a result of the comparatively loose formation of the fibers, the wearer can nevertheless breathe in and out easily. Those responsible at Oerlikon Nonwoven and FleeceforEurope, which will primarily focus on producing high-end nonwovens, and Lindenpartner, which will manufacture and distribute the protective masks, are certain of one thing: the market for protective masks has a very promising long-term future in Europe. What has been commonplace in Asia for many years now will also become normal in Europe. People will be increasingly wearing face masks when venturing out, in order to better protect themselves against health risks such as the current pandemic and also against increasing environ-mental pollution in the form of fine particles and exhaust fumes in the future.

Borealis: meltblown production on pilot line in Austria

The manufacturer of polyolefins Borealis AG, Vienna/Austria, transformed its meltblown pilot line in Linz/Austria, in short time to increase supply of polypropylene (PP) filtration fabrics for high-quality face masks.
The company has managed quickly to convert the way of working from pure development to smaller scale pilot production to regularly produce rolls of fine fiber fabrics for face masks. Recently developed by Borealis, a new proprietary polypropylene (PP) meltblown resin has boosted filtration properties due to its capability for finer fibers. By exploiting a robust network of co-operation partners in the country, Borealis is helping bolster the supply of filtration media to increase face masks production.
The newly developed Borealis HL912FB is being used to produce meltblown fabric to be applied for customised inlays in cotton-based mouth-nose masks, for conventional mouth-nose masks, and also for high-end face masks worn by medical professionals (FFP1 to FFP3). It can be processed at higher processing temperatures allowing the production of even finer fibers. According to in-house testing, the use of Borealis HL912FB results in a significant improvement in filtration efficiency. All 3 grades are manufactured at Borealis facilities in Europe and made available to customers worldwide.
