From the Sector

• 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.

Huntsman Textile Effects, a global leader in innovative solutions and environmentally sustainable products, is featuring high-performance end-to-end systems for protection effects and sustainable solutions for any wear at Performance Days on April 27-28, 2022, in Munich, Germany.

With more consumers seeking comfort and protection when buying sportwear, they expect their sports apparel to dry quickly, resist stains and odors, and offer breathability. Achieving these functionalities with on-trend aesthetics whilst realizing sustainability, are possible.

Resource saving solutions
Huntsman will introduce the AVITERA® SE Fast process at Performance Days. The revolutionary technology delivers the lowest environmental impact for dyeing polyester-cellulosic (PES-CO) blends. It combines alkali-clearable TERASIL® W/WW disperse dyes and AVITERA® SE reactive dyes to cut processing time from around nine hours to just six, helps mills reduce the water and energy required for production by up to 50% and increases output by up to 25% or more while delivering outstanding wet-fastness to ensure that sportswear will not bleed or stain during home laundering, or while in storage or transit.

EROPON® E3-SAVE is another next-generation water saving innovation. An all-in-one textile auxiliary for PES processing, it allows pre-souring, dyeing and reduction clearing to be combined in a single bath and eliminates the need for anti-foaming products, which shortens processing time and saves water and energy.

Eco-friendly stain and rain resistance
In partnership with Chemours, Huntsman will present the new eco-friendly finishes that repel water and stains, and help garments looking new for longer. Teflon™ EcoElite with Zelan™ R3 technology contains 63% plant-based materials and is the industry’s first renewably sourced water-repellent finish. It exceeds performance levels possible with traditional fluorinated technologies, with excellent water repellency and durability while reserving breathability.

Innovative odor control solutions
Huntsman will also showcase revolutionary antimicrobial and odor-control solutions as part of their partnership with Sciessent. Sciessent’s latest anti-odor technology – NOBO™ specifically developed to reduce odors in natural and synthetic fabrics. It can be incorporated into virtually any fabric – from base layer and activewear tops to socks and underwear to jeans and chinos. It offers a cost-effective way to upgrade everyday garments.

In addition, the partners will also present Sciessent’s Agion Active X2®, a next-generation odor-control solution that combines advanced antimicrobial and odor-absorbing technologies to both capture and fight odor-causing bacteria, and Lava X2®, a standalone odor adsorption product and key component of Agion Active X2® that attracts, absorbs and degrades odors for long-lasing odor protection.

• Evopreg® range expanded with unidirectional fibre-reinforced thermoplastic tapes

Composites Evolution, a developer, manufacturer and supplier of prepregs for the production of lightweight structures from composite materials, has announced the launch of a new range of unidirectional thermoplastic tapes, to sit alongside its existing line-up of Evopreg® prepregs. The first product families being launched are Evopreg® PA polyamide tapes, and Evopreg® PP polypropylene tapes, with further product lines expected as new customer requirements emerge.

Thermoplastic tapes, also known as thermoplastic prepregs, can be used in a wide variety of markets and applications, including flexible pipes for oil & gas and water transportation, pressure vessels (for example; hydrogen storage tanks and compressed natural gas tanks), and for providing local reinforcement to pre-formed components.

Marketing Director, Ben Hargreaves, explains further: “Our state-of-the-art manufacturing line gives us the capability to produce tapes on an industrial scale, using a variety of combinations of fibre and polymer. This is complemented by a pilot-scale line that allows us to carry out development trials, or manufacture small quantities of tape if required.”

“Because they can be repeatedly re-formed (via the application of heat and pressure), Evopreg® thermoplastic tapes are also very well-suited to multi-stage processing, meaning they are an excellent choice for producing hybrid structures, inserts or over-moulded components. In addition, this ability to be repeatedly re-formed opens the door to much easier recycling than is currently possible with thermoset composites.”

Hexcel announces its latest HexPly® XF surface technology that reduces shell manufacturing time within the wind blade surface finishing process. HexPly XF increases overall blade manufacturing efficiency by reducing time in the mold by up to two hours and by banishing surface defects that require rework before painting.

Hexcel’s HexPly XF surface technology has been formulated to address the limitations of current blade shell surfacing techniques whereby pinholes and other surface defects have to be repaired by hand to achieve the perfectly smooth surface required for painting.

HexPly XF surface technology introduces a new material format as the surface finishing layer, eliminating the need for a traditional in-mold gel coating process. HexPly® XF for infused rotor blades, is a lightweight non-woven semi-preg construction, comprising an epoxy resin matrix, that co-cures with standard epoxy infusion systems. The product has a successful track record in prepreg blades and has now been adapted for infusion processes.

Easy to handle and supplied in a ready to use roll form, HexPly XF can be quickly applied by hand or with semi-automated layup equipment. It features one self-adhesive, surface finishing side - indicated by a removable protective foil. This side of the prepreg is placed against a release agent treated mold surface. Once the material has been positioned, the lay-up of the blade shell structure can start immediately, and the laminate can be infused. After curing, the blade is de-molded with the manufacturer benefitting from a pinhole-free surface that needs minimal preparation before painting.

HexPly XF material is less than half the weight of a typical gel coat per square meter, reducing the overall weight of the blade. Additionally, the consistent areal weight and thickness of the prepreg film provide a completely uniform surface coating, ensuring blade weight distribution and balance are maintained, which is critical as rotor diameters continue to increase. With no need to handle or mix liquid chemicals as in the gel coat process, HexPly® XF also improves the health and safety working conditions on the shop floor.

The material has a shelf life of six weeks at ambient temperature, which also minimizes cold storage requirements and helps to reduce scrap.

"Datacenter in a box" is the new powerful, flexible and secure IT infrastructure solution for the textile industry of the future

Remscheid/Berlin – Oerlikon Manmade Fibers Segment Industrie 4.0 solutions for the production of polyester, nylon and polypropylene are based on the digitalization of the production landscape and the intelligent processing of the flood of data generated in this way. In the future, the segment will offer its customers a new powerful, flexible and, above all, secure IT infrastructure. The "Datacenter in a box" was presented for the first time at the OpenStack Summit in Berlin, Germany, to a broad specialist audience. The compact datacenter works on the basis of the open operating system OpenStack, which enables virtual computing in a secure private cloud environment.

Externally, the datacenter looks unspectacular: The box contains standard hardware such as server rack, network components, batteries for reliability, monitoring sensors and a few more things. But what counts are the inner values. The Open Source software OpenStack consists of many different services and allows the virtualization of a large pool of computing, storage and network resources in a flexible, scalable private cloud. This brings two central advantages: On the one hand, virtual operation reduces costs and simplifies configuration, adaptation and expansion of the IT infrastructure today and tomorrow. On the other hand, long-cherished wishes for high data protection are fulfilled, because a private cloud maintains secure, highly encrypted data connections away from the World Wide Web.

"The functional diversity of a cloud, operation and hardware in one's own four walls at the same time – our customers immediately understood these advantages" reports Mario Arcidiacono, specialist for Business Intelligence & Data Warehouse at the Oerlikon Manmade Fibers Segment. The IT architecture also guarantees infrastructure management without downtime, the system and virus protection are automatically kept up to date at all times. Another major advantage is the scalability of the hardware and software, which can be adapted to changing requirements.

OpenStack Summit: Project example with yarn manufacturer from Vietnam presented

With these trump cards and a project example, the Group segment confidently presented itself to a genuine specialist audience in mid-November. At this year's OpenStack Summit in Berlin, where thousands of cloud professionals met, Oerlikon Manmade Fibers Segment CEO Georg Stausberg presented the customer installation at Century Synthetic Fibre Corporation, which supplies many well-known sporting goods manufacturers. The Vietnamese producer of high-quality yarns not only uses the new datacenter, but also the connection to the new "Common Service Platform (CSP)" of the Oerlikon Manmade Fibers Segment as well as an innovative new dashboard solution in prototype status. In this case, the digital instrument panel supports employee communication during shift changes in the yarn factory and introduces agile methods into the work process. The board visualizes the progress of central key figures and operating parameters from the current production process. Based on this, the employees of the successive shifts can now exchange important process and quality information and possible instructions for action within a few minutes in a structured stand-up meeting. "For the customer this means an immediate improvement of the processes, and he can significantly increase the efficiency and quality of his employees' work," assures Joerg Gross, Senior Manager in the IT-architecture team at the Oerlikon Manmade Fibers Segment.

New IT-basis for the Plant Operation Center (POC) already successful established on the market

The fixed connection to the "Common Service Platform (CSP)" of the Oerlikon Manmade Fibers Segment plays a pioneering role in such solutions. This enables services and software updates to be provided smoothly, quickly and automatically. In this way, service applications can transform collected data into instructions or automated commands to secure and improve processes. For example, the secure availability of management solutions such as the Plant Operation Center (POC) for process monitoring can be increased and possible errors can be rectified very quickly. The new digital solution AIM4DTY (AIM = Artificial Intelligence Manufacturing), which was unveiled at the ITMA ASIA + CITME 2018 in Shanghai, China, a few weeks ago, can also be implemented in this way. AIM4DTY uses methods of machine learning, determines probable causes of errors in texturing and helps to improve quality during production.

Launch at ITMA Barcelona 2019

The Oerlikon Manmade Fibers Segment offers such remote-supported services on request. Data will therefore only be transferred to the “Common Service Platform (CSP)” with the customer's consent. In addition, all data is processed in accordance with the new European General Data Protection Regulation (GDPR) and all other international data protection standards. Against this backdrop, the Oerlikon Manmade Fibers Segment plans to provide its datacenter with graded or customer-specific solutions: from complete service to provision with customer training for its own operations. After initial practical experience with several pilot customers, the segment intends to launch its offering on the market next year and officially present it to the textile industry at ITMA 2019 in Barcelona, Spain.

The Mechanical Engineering Industry Association (VDMA) has awarded two prizes to graduates of the Institut für Textiltechnik (ITA) of RWTH Aachen University - the dissertation prize and the creativity prize of the Walter Reiners Foundation of German Textile Machinery 2018. ITA alumnus Dr Benjamin Weise was awarded the dissertation prize for the development of novel fibres for textile charge storage devices. For their work on a guide to 4D product design, Jan Merlin Abram and Aalon Tal (both ITA students) were honoured with the creativity prize. The dissertation prize is endowed with €5,000 whilst the creativity prize contains a one-year scholarship of €250 per month. Peter D. Dornier, President of the Walter Reiners Foundation and Chairman of the Management Board of Lindauer DORNIER, presented the awards on the 18 September 2018 at the 18th Textile Machinery Forum in the Digital Capability Center in Aachen, Germany.

Graphene revolutionizes all-in-one - supercaps, reduction of terahertz radiation and antistatics

In his dissertation "Development of graphene-modified multifilament yarns for the production of textile charge storage devices", laureate Dr Benjamin Weise developed novel fibres made of polyamide and graphene and further processed them into textile surfaces. The newly developed polyamide graphene fibres are featuring a multitude of advantages:

• Due to their high performance in the charge storage area, they are predestined for use in double-layer capacitors, so-called super capacitors, or supercaps in short. Compared to lithium-ion batteries, supercaps offer significantly higher power density and a longer lifetime as no chemical reactions are taking place. towing to the graphene platelets in the filaments, it is now possible for the first time to integrate a charge storage device directly into a textile without having to sew in a rechargeable battery. This new fibre is therefore suitable for prospective use in smart textiles, for instance in a textile defibrillator.
• The new graphene-modified polyamide fibres can attenuate inident terahertz radiation up to 25 % of their original intensity. Terahertz radiation, for example, offers transmission rates of 100 Mbit/sec and is therefore of high interest for high-performance wireless communication. However, the radiation could damage sensible electronics as in aircrafts if this technology will be used widespread. Consequently, the shielding of the radiation is of high importance, e.g. in the form of fibre composite components in the aircraft, which protect the on-board electronics.
• As the fibres are showcasing a dissipative electrical conductivity, personal protective equipment is another prospective field of application.  

The development of a pilot process for graphene-modified fibres and the production of textile demonstrators are novel and disruptive attainments of Dr Weise’s PhD thesis and the reason for the award ceremony to him. Due to its outstanding properties, the European Union is funding research on graphene within the frame of the "Graphene Flagship" with an overall budget of one billion Euro (source: http://graphene-flagship.eu/project/Pages/About-Graphene-Flagship.aspx).

Modular product design of 4D products is now possible in simplified form

How can three-dimensional products change their shape over time and thus become "four-dimensional"? The students Jan Merlin Abram and Aalon Tal provide answers to this question in their project work "Leitfaden zur Auslegung hybrider morphender Textilien am Beispiel eines Scharniers" (Guidelines for the Design of Hybrid Morphing Textiles Using the Example of a Hinge), for which they were awarded the creativity prize. In their work, the students offer a guideline for the development of a four-dimensional textile from the idea to the demonstrator. Four-dimensional textiles, for example, consist of a hybrid material of elastic textile on which three-dimensional structures are printed. The fourth dimension describes the change in shape and/or a property over a defined period of time (= morphing).  This change is caused by external influences such as light and heat.

Every year, the Foundation of the German Textile Machinery awards prizes for the best dissertation, diploma or master's thesis and the creativity prize for the smartest student research project. Further prizes were awarded to Eric Otto, ITM Dresden, and Susanne Fischer, Reutlingen University.

Exhibiting at this week’s Association for Professionals in Infection Control and Epidemiology (APIC) Annual Conference, Hygienically Clean Healthcare certified laundries provided nearly 200 copies of a training video guiding caregivers in improving soiled linen handling performance.

Provided on a flash drive: the 13-minute video (The Six Cs: Handling Soiled Linen in a Healthcare Environment), a quiz to immediately assess viewers’ grasp of the video’s lessons and posters to reinforce these year-round. Distributed since 2016, the video has been hailed for its value in aiding compliance with OSHA universal precautions regarding items saturated with blood, bodily fluids, harmful residue from treatments and other potentially infectious material.

The flash drive offer intrigued infection preventionists (IPs) from a single facility or those responsible for this function throughout health systems, whether acute or outpatient care environments or both. The drive also attracted the attention of other professionals who visited the Hygienically Clean exhibit, such as federal and state health officials and suppliers of products and services to the IP profession.

Distributing the flash drive is a hallmark of the Hygienically Clean program’s philosophy of addressing healthcare providers’ operational needs outside the scope of outsourced laundries’ traditional functions. Certified operators’ certification fees provide funding for creating and distributing the video and other education tools for healthcare facilities.

Visitors to the Minneapolis display who previously received the video vouched for its effectiveness. Certified laundries have individually distributed the flash drive to customers and prospects in addition to  their collective effort to provide them at previous APIC and Association for the Healthcare Environment (AHE) expos.

The video’s easy-to-follow steps improve infection control and patient care and reduce costs by addressing OSHA-required universal precautions. Employees who handle soiled linen (usually nurses and environmental services staff) must assume all human blood and potentially infectious materials they touch are infected, because they can’t be sure which patients are infected or what infections are present.

Adhering to the six Cs (cover, collect, contain, consolidate, clean, cooperate) each day prevents injury and reduces the risk of spreading of infection to co-workers, patients and residents. These positive outcomes are only achieved when workers first protect themselves.

The flash drive is available to all healthcare providers at no cost. It also contains the Hygienically Clean standard and other guidance documents for infection preventionists related to linen and uniforms. Among these documents: Handling Clean Linen in a Healthcare Environment, an 8-page guide to safeguarding through effective transportation, storage and distribution.
