From the Sector

In accordance with California’s Proper Labeling of Wet Wipes law (AB 818), state wastewater agencies and industry experts went deep to find out exactly what is passing through—and clogging up—municipal wastewater systems. The Responsible Flushing Alliance (RFA) alongside the California Association of Sanitation Agencies (CASA) and the Association of the Nonwoven Fabrics Industry (INDA) released the results from the largest known domestic sewage collection study conducted to reveal what’s really being flushed down the drain – and shouldn’t be.

“We took a forensic approach to this collection study, engaging industry and wastewater experts to examine our findings and determine what exactly is being flushed and how much of it,” said Adam Link, Executive Director at CASA, a co-sponsor of the Proper Labeling of Wet Wipes Law. “Now that we have the data to see what Californians are flushing and the types of non-flushable items that are causing issues within wastewater systems, local agencies can refine their public outreach and messaging to target specific problems and educate more efficiently.”

Collection and material investigation took place in October 2023 at two locations: Inland Empire Utilities Agency (IEUA) in Southern California and Central Contra Costa Sanitary District (Central San) in the greater San Francisco Bay Area in Northern California. Wastewater and wipes experts collected, sorted and identified more than 1,700 items pulled from the two locations during peak flow times. Kennedy Jenks, an independent engineering firm, designed the study and compiled the findings into the report.

Why Study What’s Being Flushed?
When products that aren’t meant to be flushed down the toilet wind up in the sewer system, it can cause serious threats to public and environmental health. In fact, estimates show that local public agencies throughout California (and the ratepayers they represent) are spending more than $47 million annually to repair wastewater treatment equipment and respond to sewer overflows caused by improper flushing.

“Part of keeping communities healthy requires not flushing things we shouldn’t,” said Lara Wyss, President of the RFA. “However, the data to support which non-flushable items to target as part of education campaigns has been lacking. That’s likely why when we surveyed Californians about what they are flushing, the results revealed that approximately 25% think baby wipes are flushable (which is never true) and 60% self-reported that they flushed something they knew they shouldn’t have.2 Our study results reinforce that finding, as more than 99% of materials collected were items that shouldn’t have been flushed.”

The breakdown of items collected from pipes at the two study locations included:
•    34.1% wipes labeled with the “Do Not Flush” symbol (baby wipes, cleaning wipes, makeup wipes, etc.)
•    64.9% other non-flushable items (paper towels, period products, trash, etc.)
•    0.9% wipes labeled as flushable

“We pulled material larger than 1-inch square directly from the bar screens, and it wasn’t until everything was sorted and identified that we could see what we actually had,” said Matt O’Sickey, Director of Education and Technical Affairs, INDA. “There were a lot of paper towels and baby wipes and all of the ‘Do Not Flush’ labeled wipes we collected were fully intact, showcasing why they should never be flushed.”

What Not to Flush—and How We Tell Consumers
According to the Proper Wet Wipes Labeling law, manufacturers of non-flushable wipes, including products such as baby wipes, cleaning wipes, makeup removal wipes and many others that are primarily used in a bathroom setting must include the “Do Not Flush” symbol on the front of the packaging.
The #FlushSmart consumer education campaign promotes the “Do Not Flush” symbol and provides information on what should and should not be flushed. The message shared with consumers is simple: Look for the “Do Not Flush” symbol on wipes packaging, and if you see it – throw the wipe out. Extrapolating from the results of this study, refraining from flushing “Do Not Flush” labeled wipes, paper products and feminine hygiene products would capture over 90% of items clogging sewers.

Cavitec, part of Santex Rimar Group, presents the redesigned Caviscreen at Techtextil Frankfurt. Caviscreen features latest technology for breathable laminates.

Caviscreen was developed as a hotmelt coating and laminating unit for breathable sportswear, rainwear and protective clothing – with and without applying a membrane. The redesigned machine shows a brand-new method to supply adhesive more evenly and precisely. Using PUR adhesive (polyurethane reactive adhesive) goes with additional benefits like strong bonding capabilities and versatility.

Caviscreen’s hotmelt screen printing is a special system for high-end application garments. With this Caviscreen system, a PUR adhesive is transferred onto the substrate through a rotary screen, similar to the well-established textile printing method. The adhesives are fed from the drum melter through a heated hose to the traversing adhesive distribution system inside the rotary screen, just behind the doctor blade.

The adhesive is pressed by the doctor blade through the screen holes and transferred to the substrate. Different dot pattern (mesh or irregularly) and different screen thicknesses allow different coating weight and adhesive coverages.

The traversing adhesive dispenser is used to distribute the adhesive automatically over the set working width that – an additional technical benefit – can be set without any mechanical changes.

Cavitec’s screen coating system achieves high bonding strength while using less adhesive than other coating processes, because of applying the coating on the surface of the substrate and like this, the adhesive has less tendency to penetrate the substrate.

Bonding strength, softness of the fabric and the breathability are defined by the coating weight and the coverage. The rotary screen allows users to regulate and adapt the coverage respectively the coating weight. Cavitec offers a large selection of screens that are essential to fulfil the fabric requirements. A further advantage is the ease and efficiency of switching from one screen to another by simply unlocking the bayonet fitting. The IR-heater cover opens pneumatically and the lightweight screen can be easily removed by hand. Unlike with other methods, there's no need to deal with hot oil or any other heated liquid that requires cooling down.

The Caviscreen technology supports manufacturers by reducing costs with screens priced at a mere fraction, just 10%, of common gravure roller prices.

Trützschler expanded their portfolio to become the first full-liner in the preparation of textile waste – from mechanical recycling to the spinning preparation of torn secondary fibers.

The TRUECYCLED solution is the result of their cooperation with the company Balkan Textile Machinery INC.CO. in Turkey, which they announced at the ITMA 2023 trade event in Milan. Since then, Trützschler has received many inquiries for recycling systems.

Success with a systems approach
Recycling systems face significant technological challenges. On average, torn fibers are much shorter than virgin fibers. The percentage share of short fibers in the fiber mass is much higher. Unopened yarn and fabric particles are also difficult to process. Not surprisingly, much academic and practical research is currently conducted to find solutions for these problems. Dr. Georg Stegschuster, a researcher specializing in textile recycling, believes a systems approach is needed. He is working at the Recycling atelier, a model factory for mechanical recycling in Augsburg, Germany, which is committed to delivering the latest technological insights for textile recycling. “A perfect fine-tuning between tearing and spinning preparation is key for obtaining the best possible quality results and avoiding unnecessary fiber shortening,” he says. “This can be achieved if you are in control of both processes – and have the necessary expertise for both processes too.”

Gentle but effective
In some cases, for example, it may be advantageous to have less aggressive settings in the tearing line. This can help avoid unnecessary fiber shortening. The remaining higher share of unopened fabric must then be handled in a high-performance spinning preparation line. This starts with the right blow room configuration for perfect opening, cleaning and blending. A card that is specially designed for recycling materials, such as the new TC 30Ri, can also enable gentle but effective treatment of fibers.

A shortened drafting process is also a must. The integrated draw frame IDF 3 can make this possible. The draft is high enough to provide excellent levelling of the numerous short fibers, but low enough to prevent floating fibers.

Full-liner in mechanical recycling and preparation of textile waste
Trützschler now offers a complete system covering the whole process, from cutting and tearing textile waste through to carding and drawing secondary fibers. Thanks to this holistic approach and Trützschler’s expertise for the whole process, manufacturers can avoid unnecessary fiber shortening.

ACG Kinna Automatic and ACG Nyström – members of TMAS, the Swedish textile machinery association – have delivered the first microfactory for the production of fully finished filter bags to an international filtration industry customer, in cooperation with JUKI Central Europe.

The microfactory’s configuration is based on two separate interconnecting modules – the Smart Filter Line (SFL) and the Filtermaster 2.0. The SFL handles the fabric feeding from rolls and its folding prior to seam construction, which can either be by automatic sewing, welding or with sewing and taping, depending on specifications. Very rapid changeover of the modular seaming methods can be achieved during product changes. The specific size of the now fully-tubular fabric is then precisely cut to size for each individual unit and further folded ready to be fed into the Filtermaster 2.0. The Filtermaster 2.0 then automatically attaches the reinforcement, bottom and snap rings onto the filter tube with a second Juki sewing head on a robotic arm, to form the fully finished filter bag ready for packaging.

Filter bags are employed in a wide range of industrial processes and while they may be largely under the radar as products, they represent a pretty significant percentage of overall technical textiles production.
They are used in foundries, smelters, incinerators, asphalt plants and energy production plants. Other key manufacturing fields – often where dust is generated – include the production of timber, textiles, composites, waste handling and minerals, in addition to chemicals, food production, pharmaceuticals, electronics and agriculture.

As a further example of the scale of the industry and the high volumes of fabrics involved, one supplier has delivered a single order of 30,000 filter bags to be used for flue gas cleaning at a European power plant. The bags can also be anywhere up to twelve metres in length and frequently have to be replaced.

Glen Raven hosted United States Trade Representative (USTR) Ambassador Katherine Tai in an important visit to the company’s yarn spinning manufacturing facility and headquarters for its Sunbrella® flagship brand in Burlington, N.C. followed by an industry supply chain roundtable.

Ambassador Tai’s visit coincides with USTR’s Federal Register notice for public input to inform the administration’s development of trade and investment policy initiatives related to a domestic supply chain resilience plan.

USTR has highlighted domestic textiles as a critical part of the supply chain. The textile sector, which includes yarns, fabrics, apparel and other finished goods, will be part of its fact-finding investigation into shaping policy tools that could be deployed to enhance supply chain resilience. The office is requesting input on policies that are currently working well for these sectors, and those that are not working well, in advancing domestic supply chains.

The Ambassador’s visit to Glen Raven included a tour of the Sunbrella facilities, a design and innovation center, and a roundtable discussion with several other textile executives based in North Carolina who highlighted the significant impact of the sector to the U.S. economy.

Glen Raven, a family-owned company founded in 1880, operates five manufacturing facilities in North and South Carolina employing 2,500 people, including their joint venture with Shawmut Corporation. The company is currently in the process of scaling a $250 million multi-phase U.S. capacity expansion plan of its facilities and infrastructure to meet customer demand.

In the fringes of the EU Research and Innovation Days, the European Commission has announced 9 new European co-funded and co-programmed partnerships, including “Textiles of the Future”. These partnerships will be at the core of the Horizon Europe Strategic Plan 2025-2027, addressing the green and digital transition, and a more resilient, competitive, inclusive and democratic Europe.

EURATEX has been working towards such a partnership over the last few years. Investing in innovation is a critical component to successfully implement the EU Strategy for Sustainable and Circular Textiles. EURATEX therefore welcomes the Commission’s decision, as a measure to help their 200.000 EU textile companies to remain competitive.

The Textiles of the Future Partnership will be co-managed by the European Technology Platform for Future of Textiles and Clothing (ETP). With a deep knowledge in textiles research and a vast innovation network, ETP stands ready to bring that partnership into reality.

The DITF is leading the joint project "DACCUS-Pre*". The basic idea of the project is to develop a new building material that stores carbon in the long term and removes more CO₂ from the atmosphere than is emitted during its production.       

In collaboration with the company TechnoCarbon Technologies, the project is now well advanced - a first demonstrator in the form of a house wall element has been realized. It consists of three materials: Natural stone, carbon fibers and biochar. Each component contributes in a different way to the negative CO₂ balance of the material:

Two slabs of natural stone form the exposed walls of the wall element. The mechanical processing of the material, i.e. sawing in stone cutting machines, produces significant quantities of stone dust. This is very reactive due to its large specific surface area. Silicate weathering of the rock dust permanently binds a large amount of CO₂ from the atmosphere.

Carbon fibers in the form of technical fabrics reinforce the side walls of the wall elements. They absorb tensile forces and are intended to stabilize the building material in the same way as reinforcing steel in concrete. The carbon fibers used are bio-based, produced from biomass. Lignin-based carbon fibers, which have long been technically optimized at DITF Denkendorf, are particularly suitable for this application: They are inexpensive due to low raw material costs and have a high carbon yield. In addition, unlike reinforcing steel, they are not susceptible to oxidation and therefore last much longer. Although carbon fibers are more energy-intensive to produce than steel, as used in reinforced concrete, only a small amount is needed for use in building materials. As a result, the energy and CO₂ balance is much better than for reinforced concrete. By using solar heat and biomass to produce the carbon fibers and the weathering of the stone dust, the CO₂ balance of the new building material is actually negative, making it possible to construct CO₂-negative buildings.

The third component of the new building material is biochar. This is used as a filler between the two rock slabs. The char acts as an effective insulating material. It is also a permanent source of CO₂ storage, which plays a significant role in the CO₂ balance of the entire wall element.

From a technical point of view, the already realized demonstrator, a wall element for structural engineering, is well developed. The natural stone used is a gabbro from India, which has a high-quality appearance and is suitable for high loads. This has been proven in load tests.  Bio-based carbon fibers serve as the top layer of the stone slabs. The biochar from Convoris GmbH is characterized by particularly good thermal insulation values.

The CO₂ balance of a house wall made of the new material has been calculated and compared with that of conventional reinforced concrete. This results in a difference in the CO₂ balance of 157 CO₂ equivalents per square meter of house wall. A significant saving!

Lightweight design is a key enabler for addressing the energy transition and sustainable economy. Following the liquidation of the state agency Leichtbau BW GmbH, a consortium consisting of the Allianz Faserbasierter Werkstoffe Baden-Württtemberg (AFBW), the Leichtbauzentrum Baden-Württemberg (LBZ e.V. -BW) and Composites United Baden-Württemberg (CU BW) now represents the interests of the lightweight construction community in the State.

The Lightweight Design Agency for Baden-Württemberg is set up for this purpose on behalf of and with the support of the State. The Lightweight Construction Alliance BW is the central point of contact for all players in the field of lightweight construction in the State and acts in their interests at national and international level. Professor Markus Milwich from the German Institutes of Textile and Fiber Research Denkendorf (DITF) represents the agency.

The use of lightweight materials in combination with new production technologies will significantly reduce energy consumption in transportation, the manufacturing industry and the construction sector. Resources can be saved through the use of new materials. As a cross-functional technology, lightweight construction covers entire value chain from production and use to recycling and reuse.

The aim of the state government is to establish Baden-Württemberg as a leading provider of innovative lightweight construction technologies in order to strengthen the local economy and secure high-quality jobs.

Among others, the "Lightweight Construction Alliance Baden-Württemberg" will continue the nationally renowned "Lightweight Construction Day", which acts as an important source of inspiration for a wide range of lightweight construction topics among business and scientific community.

Professor Milwich, an expert with many years of experience and an excellent network beyond the State's borders, has been recruited for this task. In his role, Milwich also represents the state of Baden-Württemberg on the Strategy Advisory Board of the Lightweight Construction Initiative of the Federal Ministry for Economic Affairs and Climate Action, which supports the cross functional-technology and efficient transfer of knowledge between the various nationwide players in lightweight construction and serves as a central point of contact for entrepreneurs nationwide for all relevant questions.

From 2005 to 2020, Professor Milwich headed the Composite Technology research at the DITF, which was integrated into the Competence Center Polymers and Fiber Composites in 2020. He is also an honorary professor at Reutlingen University, where he teaches hybrid materials and composites. "Lightweight design is an essential aspect for sustainability, environmental and resource conservation. I always showcase this in research and teaching and now also as a representative of the lightweight construction community in Baden-Württemberg," emphasizes Professor Milwich.
