From the Sector

Many people across the world are bedridden – be it due to illness, an accident or old age. Because those affected often cannot move or turn over by themselves, they often end up with very painful bedsores. In the future, it should be possible to avoid bedsores with the help of materials that can be programmed to entirely adapt their form and mechanical properties. For example, the body support of mattresses made from programmable materials can be adjusted in any given area at the push of a button. Furthermore, the support layer is formed in such a way that strong pressure on one point can be distributed across a wider area. Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Materials and microstructuring
Materials for applications requiring specific changes to stiffness or shape are being developed by researchers from Fraunhofer CPM, which is formed of six core institutes with the aim of designing and producing programmable materials. So, how can we program materials? “Essentially, there are two key areas where adjustments can be made: the base material – thermoplastic polymers in the case of mattresses and metallic alloys for other applications, including shape memory alloys – and, more specifically, the microstructure,” explains Dr. Heiko Andrä, spokesperson on the topic at the Fraunhofer Institute for Industrial Mathematics ITWM, one of the Fraunhofer CPM core institutes. “The microstructure of these metamaterials is made up of unit cells that consist of structural elements such as small beams and thin shells.” While the size of each unit cell and its structural elements in conventional cellular materials, like foams, vary randomly, the cells in the programmable materials are also variable – but can be precisely defined, i.e., programmed. This programming can be made, for example, in such a way that pressure on a particular position will result in specific changes at other regions of the mattress, i.e., increase the size of the contact surface and provide optimal support to certain areas of the body.

Materials can also react to temperature or humidity
The change in shape that the material should exhibit and the stimuli to which it reacts - mechanical stress, heat, moisture or even an electric or magnetic field - can be determined by the choice of material and its microstructure.

The journey to application
A single piece of material can take the place of entire systems of sensors, regulators and actuators. The goal of Fraunhofer CPM is to reduce the complexity of systems by integrating their functionalities into the material and reducing material diversity. We always have industrial products in mind when developing the programmable materials. As such, we take mass production processes and material fatigue into account, among other things,” says Franziska Wenz, deputy spokesperson on the topic at the Fraunhofer Institute for Mechanics of Materials IWM, another core institute of Fraunhofer CPM. The initial pilot projects with industry partners are also already underway. The research team expects that initially, programmable materials will act as replacements for components in existing systems or be used in special applications such as medical mattresses, comfortable chairs, variable damping shoe soles and protective clothing. “Gradually, the proportion of programmable materials used will increase,” says Andrä. Ultimately, they can be used everywhere – from medicine and sporting goods to soft robotics and even space research.

• ESD protection in harsh environments:
• Polymer-coated chemical-resistant fabrics and fireproof special textiles with expanded electrostatic discharge (ESD) safety function have been developed.
• Graphene nanotubes used as an electrostatic dissipative material make it possible to add ESD protection without compromising resistance to aggressive environments.
• Efficient working loadings starting from 0.06% are sufficient for stable anti-static properties fully compliant with safety standards and position graphene nanotubes far ahead of other conductive materials.

Protective clothing, upholstery, and industrial fabrics that experience harsh conditions require advanced performance. Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.
 
In applications where multifunctionality of textile is required, graphene nanotubes overcome the limitations of other conductive materials such as unstable anti-static properties; degradation of strength, or chemical or fire resistance; complicated manufacturing processes; dusty production; carbon contamination on the material’s surface; or limited color options. Recent developments show that graphene nanotubes provide ESD protection to textiles in full compliance with safety standards and without degrading the textile’s resistance to harsh environments, greatly enhancing the value of textiles.
 
One such example is textiles coated with fluoroelastomer (a polymer that is highly resistant to chemicals) augmented with graphene nanotubes from OCSiAl. Nanotubes provide the material with surface resistivity of 10^6–10^8 Ω/sq compliant with EN, ISO, and ATEX standards for personal protective equipment. This new technology opens the door for the fabric to be used in high-level protective suits, combining exceptional protection from chemicals with electrostatic discharge protection.
 
Another example is how graphene nanotube technology is being acknowledged as a replacement for metal yarns in fireproof and anti-static textiles, protecting against sparks, splashes of molten metal, high temperatures, and the risk of sudden electrostatic discharge. While metal yarns require a specific knitting process and storage conditions, incorporating nanotubes in a fabric does not require any changes in the manufacturing process as the water-based dispersion is introduced into the fabric at the fluoro-organic treatment stage. The fabric with OCSiAl’s graphene nanotubes has been proven to maintain the pre-set level of ESD protection (surface resistance of 10^7 Ω) after numerous washes.
 
Permanent and stable electrical conductivity, facilitated by graphene nanotubes, is not only a matter of safety but brings additional value in augmenting dust-repellent properties and touchscreen compatibility for comfort and time savings. At the same time, the ultralow nanotube concentrations result in maintained manufacturing processes and mechanical properties, and improve product aesthetics by making it possible to use a wide range of colors. Altogether, these benefits allow textile manufacturers to create next-generation special textiles with expanded functionality.

DiloGroup will be attenting India ITME 2022 (December 8 – 13, 2022), an exhibition for the textile industry, which offers a central forum for dialogue within the textile production sector, including textile machine building, fibre production, ancillaries and accessories. For DiloGroup this event is a good oppportunity to inform customers and interested parties about new developments aimed at improving production technologies with a focus on needlefelts.

Focal points of the development work are:

1. Intense Needling:
   The development efforts of DiloGroup aim at producing nonwovens by “intense needling” instead of water entangling, even for light nonwovens made of fine fibres for the medical and hygiene sector with an area weight of 30 – 100 g/m². This would result in a reduction of the environmentally relevant production costs; per annum to about 1/3 to 1/5 of current.
2. “Fibre Pulp Recycling”
   Fibrous material in nonwovens and particularly used clothes can be successfully recycled, if staple length can be conserved in the tearing process. In the classical tearing process, staple lengths are dramatically reduced and therefore these fibres can only be used as base material for inferior uses in thermal or acoustic insulation or in protective textiles, transportation or protective covers etc.
   When recycling textile waste in the context of the collection of used clothes, the so called “filament-saving” tearing using special tearing machines and methods must be used to produce fibres with longer staple lengths which can be fed to a nonwoven installation. Hence product characteristics can be better specified and controlled.
3. Additive nonwoven production
   The additive production method of the “3D-Lofter” is especially suited for automotive parts with differently distributed masses. It is also suited for uses in the sector of apparel and shoe production.
4. “IsoFeed”-card feeding
   In the field of card feeding, the “IsoFeed” method offers great potential for a more homogeneous card feeding at the same time reducing the variation in cross-machine fibre mass distribution and thus the fibre consumption while conserving the end product quality.

As an accredited testing and certification body, the “OETI - Institut fuer Oekologie, Technik und Innovation GmbH“ (OETI for short) has been successfully responding to prevailing market requirements for 55 years and, in the process, has made a name for itself worldwide. To mark its anniversary, this international centre of excellence with its origins in Austria is taking a look back at the most important milestones in its history as well as providing interesting insights into future developments.

As renowned flooring manufacturers founded the Austrian Carpet Institute on 25th of September 1967, no one could have imagined how successful the company would become. But even back then, one thing was clear to the experts: the need to establish a carpet research and testing centre in the form of an association. Today, over five decades later, OETI is a testing and certification services provider for OEKO-TEX® certificates and labels, textiles, leather, due diligence along the textile and leather supply chain as well as for personal protective equipment (PPE), flooring technology, furnishings and indoor air quality.

In 1992, OETI was a founding member of the ‘International OEKO-TEX® Association for Research and Testing in the Field of Textile and Leather Ecology’ with independent certifications and product labels. Ever since, OEKO-TEX® has enabled companies along the textile and leather supply chain and every consumer to make responsible decisions for safe, environmentally friendly and fairly manufactured products.

In line with its focus on sustainability, OETI and its Swiss parent company, TESTEX AG, wanted to build the new OETI headquarters using low energy construction techniques and ensure its carbon-neutral operation. To achieve these goals, the highest possible thermal insulation and energy optimisation standards were applied, while the carbon-neutral power supply is generated by its in-house photovoltaics system as well as domestic renewable energy.

The new headquarters, which the company moved into in 2021, provides space for 75 employees over 2,500m2 and boasts bright and perfectly equipped office areas. The laboratory areas, the analytical/chemical laboratory and the physical / fire laboratory were also designed based on the latest methods and technologies. This makes OETI, alongside its Swiss parent company TESTEX, the second fully fledged laboratory site in the entire, global TESTEX Group.

The associations published a joint European textiles industry statement on the energy package claiming incisive actions with no further delay.
Here is the statement in full:

Last month, when gas wholesale prices reached the record level of 340€/MWh – triggering also sky-high electricity prices – the European textiles industry called on the European Union to adopt a wholesale price cap for gas, the revision of the merit-order principle in the electricity market, support for SMEs and a single European strategy. On 14 September 2022, on the occasion of the State of the Union address by President Von der Leyen, the Commission announced initiatives aimed at tackling the dramatic energy crisis that the Europe is facing.

We, the European associations representing the whole textiles’ ecosystem,  welcome these proposals by the Commission to change the TTF benchmark parameters and decouple the TTF from the electricity market and the revision of the merit-order principle for the electricity market, which is no longer serving the purpose it was designed for.

We also welcome the proposal to amend the state-aid framework that, in our view, should include the textiles finishing, the textiles services and the nonwoven sectors as well as a simplification of the application requirements. Furthermore, we call for a uniform implementation across the EU.

However, we acknowledge that the Commission proposal lacks in ambition and – if confirmed – it will come at the cost of losing European industrial capacity and European jobs. Ultimately, Europe will remain without its integrated textiles ecosystem, as we know it today, and no mean to translate into reality the EU textiles strategy, for more sustainable and circular textiles products.

An ambitious and meaningful European price cap on the wholesale price of natural gas is absolutely necessary. Europe is running out of time to save its own industry. It is now time to act swiftly, decisively in unity and solidarity at European level. We understand a very high price cap has been so far discussed among Ministries and that is not reassuring for companies across Europe: if any cap is, as expected, above 100/MWh, these businesses will collapse.

Already in March 2022, with EU gas wholesale prices at 200€/MWh, the business case for keeping textiles production was no longer there. To date, natural gas wholesale prices have reached the level of 340€/MWh, more than 15 times higher compared to 2021! Currently, many businesses have suspended their production processes to avoid the loss of tens of thousands of euros every day. We hope this will not become the new normal and – to reduce the likelihood of such a scenario – we call on the Commission, the EU Council and the Parliament to swiftly adopt decisive, impactful and concrete actions to tackle the energy crisis and ensure the survival of the European industry.

Given the dire international competition in which the EU textiles industry operates, it is not possible to just pass on the increased costs to consumers. Yet, with these sky-high prices, our companies cannot afford to absorb those costs. The EU textiles companies are mainly SMEs that do not have the financial structure to absorb such a shock.  In contrast with such reality in Europe, the wholesale price of gas in the US and China is 10€/MWh, whereas in Turkey the price is 25€/MWh. If the EU does not act, our international competitors will easily replace us in the market, resulting in the de-industrialisation of Europe and a worsened reliance on foreign imports of essential products.

Specific segments of the textile industry are particularly vulnerable:

• The man-made fibres (MMF) industry for instance is an energy intensive sector and a major consumer of natural gas and electricity in the manufacturing of its fibres. Not only is it being affected by higher energy process, it is also experiencing shortages and sharply rising costs of its raw materials.
• For the nonwovens segment, production processes – which use both fibres and filaments extruded in situ – are also highly dependent on gas and electricity. Polymers melting and extrusion, fibres carding, web-forming, web-bonding and drying are energy-intensive techniques. Nonwoven materials can be found in many applications crucial to citizens like in healthcare (face masks) or automotive (batteries).
• It also is to be noted that for some segments the use of gas has no technological substitute: for example, the dyeing and finishing production units make very intense use of gas. These production units are mainly composed by boilers and driers, which only work on gas and there is no alternative technology.
• The textile services sector is also struggling: with the critical nature of the service they provide, they require a considerable amount of energy to keep services, particularly hospitals and care homes stocked with lifesaving material as well as clothing and bed linens for the patients themselves. Losing these businesses would cause a lack of clothing for healthcare professionals, including protective sanitary gowns for surgeons, nurses and doctors, uniforms including other forms of personal protective equipment.

North Carolina textile executives spanning the fiber, yarn, fabric, and finished product textile industries participated in a roundtable discussion with Rep. Kathy Manning (D-NC), at which they discussed the innovative achievements and competitiveness of the domestic industry and outlined priority issues in Washington that impact their daily operations.

The roundtable discussion, hosted by Unifi Inc. and sponsored by the National Council of Textile Organizations (NCTO), was held at Unifi’s headquarters in Greensboro, North Carolina.

North Carolina is the second largest state employer of textile-related jobs, employing more than 30,000 jobs in 2021, according to U.S. government data. The state’s $2.7 billion in textile-related exports leads the nation, according to U.S. government data.

Congresswoman Manning’s visit comes at a pivotal time for the U.S. textile supply chain, which produced $65.2 billion in output in 2021 and employed nearly 535,000 workers. The industry has been at the forefront of domestic manufacturing of over 1 billion personal protective equipment (PPE) items during the COVID-19 pandemic.

During the roundtable, North Carolina executives showcased the industry’s important contribution to the state and the U.S. economy as well as its advanced sustainability initiatives, while outlining critical policies, such as the importance of Buy American and Berry Amendment government procurement policies, maintaining strong rules of origins in free trade agreements, supporting a domestic PPE production sector, and the need to address larger systemic trade issues with China.

“In North Carolina, the textile industry is woven into the very fabric of our state and economy, with more than 33,000 workers employed in over 600 textile manufacturing facilities across the state. In Congress, I am committed to supporting our homegrown industry by making PPE in America, protecting the yarn forward rule of origin in our trade agreements, and cracking down on China’s unfair trade practices. I am thrilled to engage with industry leaders in my district, as we discuss ways to grow the U.S. textile industry and the critical role that textile manufacturers play in our local, state, and national economy,” said Congresswoman Kathy Manning.

After three years, VUB a.s again got the chance to actively participate in the European trade fair Techtextil 2022m being present at a joint stand of Czech companies active in production and application of technical textiles, organized by Clutex - Cluster Technical Textiles.

In cooperation with partners from academic and production sphere many products were developed over the past years, sold by VUB under the brand Clevertex. For the presentation at the fair, a wide range of ESD protective clothing for the electrotechnical industry and for each worker dealing with electrostatic discharge sensitive components was on display. As well as another product line of the Clevertex brand representing wearable skincare textile products with antiseptic effects based on purely natural textile materials.

Attention was paid to the advanced solutions for smart textiles and e-textiles products esp. electrically conductive hybrid threads based on ultrafine metallic micro-wires. A significant advantage of these threads lies in their full compatibility with standard textile manufacturing processes, and possibility of customization in terms of fineness, electrical conductivity and temperature resistance of individual thread. As an example of one of the applications of conductive threads, different types of woven elastic conductive ribbons were demonstrated, which could be used as bus bars or as textile conductors wherever a variable length of conductive element is required without the negative influence on their electrical resistance during the change the length.

• Target markets: automotive, furnishings, sports and technical apparel

RadiciGroup is at Techtextil 2022, the leading European trade fair for technical textiles, taking place in Frankfurt am Main, Germany, from 21 to 24 June. On display in the RadiciGroup exhibition area are the Group’s latest products for the automotive, furnishings and apparel markets: from nylon and polyester yarn, including biosource and recycled lines, to nonwovens and the new radipeople® line of personal protective equipment (PPE).

Indeed, at Techtextil, RadiciGroup is showcasing RENYCLE®, a yarn obtained from recycled nylon; REPETABLE®, a polyester yarn from post-consumer recycled plastic bottles; RESPUNSIBLE®, a nonwoven fabric from recycled polypropylene; and BIOFEEL®, a brand identifying a yarn line obtained from renewable sources of both nylon and polyester.

Moreover, RadiciGroup is participating in a forum organized by the Technical Textiles Section of Sistema Moda Italia in collaboration with the Italian Space Agency (ICE) (Hall 12.1 – Stand C58), with the goal of introducing product innovations not only coming from a single manufacturer, but also from an innovative synergistic approach all along the supply chain, from raw materials to finished products. An example of this synergistic collaboration is the “Mars Spacesuit”, recently tested in the USA by analogue astronauts as part of a space medicine project designed to measure the vital signs of future astronauts and develop technologies to support the simulation of life in space and planetary environments. RadiciGroup teamed up with major Italian textile companies and supplied the materials to make the suits for the six analogue astronauts participating in the mission and coordinated the development of the technologies needed to create the technicalwear for use in extreme environmental conditions.

People in Brazil have a new ally in the fight against an invasive carrier of dengue fever – a mosquito-repellent coating developed by AkzoNobel’s Coral brand.
 
Known as Well-being Protection Anti-Mosquito, the colorless matt varnish contains an active ingredient called permethrin. Its repellent action is specifically designed to combat the Aedes aegypti mosquito, which was largely responsible for dengue cases in Brazil surging 165% during the first few months of 2022 – according to figures from the Brazilian Ministry of Health. As well as spreading dengue, Aedes aegypti can also transmit the zika and chikungunya virus.
 
When a mosquito lands on the new transparent topcoat, the permethrin is absorbed through its feet and over-excites the insect’s nervous system, causing it to disengage or fall off. Permethrin is a well-known repellent and is commonly used in fabrics for mosquito nets and protective clothing.

The effectiveness of Well-being Protection Anti-Mosquito was tested in an independent external laboratory, certified by the Brazilian Network of Analytical Laboratories in Health. All the tests took place on painted walls and ceilings in a life-size house environment and successfully proved that mosquitoes were repelled from the room after contact, with the active ingredient being retained in the varnish matrix.
