Smart textiles have the potential to revolutionise healthcare. In his doctoral thesis in textile technology at the University of Borås, Emanuel Gunnarsson presents unique solutions to the bottleneck that has long inhibited the market.

With an ageing population, increasing demands are being placed on healthcare and smart textiles can offer a solution where only imagination sets limits. “The long-term goal of most smart textiles is for them to be so easy to use that the user doesn't think of them as anything more than regular garments. No special procedure should be needed to use them. If we succeed in that, we won't burden healthcare by having healthcare personnel administer vital parameter monitoring such as blood pressure and pulse, as the user can handle it themselves,” said Emanuel Gunnarsson.

In his work, he has investigated how a t-shirt for measuring heart rhythm and movement patterns, and garments for electrostimulation, can be produced in a single step. This involves the connection between the contact surfaces (electrodes), the insulated conductive paths between the electrode and the contact point, and the electrical measuring equipment required.

“This, as far as we know, has never been described before. We are completely convinced that this is the solution to a significant bottleneck when it comes to getting the smart textile market going in earnest,” said Emanuel Gunnarsson.

His work has resulted in two different simple ways to produce smart textiles. He demonstrates that sensors can be integrated using standard textile manufacturing methods. The research also includes criticism of some of the methods used to measure the functionality of smart textiles, and advice on how to do it better instead.

“The next natural step will be to see how these garments cope with one of the toughest challenges a garment faces, namely washing. Especially as these garments must be worn closest to the skin, they will need to be washed relatively often,” said Emanuel Gunnarsson.

Studies from other universities indicate that the yarns used to measure signals from the body do not withstand many washes, but after a small pilot study, Emanuel Gunnarsson is hopeful of the opposite.

Faster and more cost-effective carbon fibre production - the technology of the start-up CarboScreen comes a good deal closer to this dream. The founders Dr. Musa Akdere, Felix Pohlkemper and Tim Röding from the Institut für Textiltechnik (ITA) of RWTH Aachen University are using sensor technology to monitor carbon fibre production, thereby doubling the production speed from the current 15 to 30 m/min in the medium term and increasing turnover by up to €37.5 million per year and system. This ground-breaking development also impressed the jury at the ITMF at their Annual Conference in Keqiao, China, and was honoured with the ITMF StartUp Award 2023 on 6 November 2023.

Dr. Musa Akdere accepted the award on behalf of the CarboScreen founding team.

Carbon fibres can only develop their full potential if they are not damaged during production and further processing. Two types of fibre damage occur more frequently during fibre production: Superficial or mechanical damage to the fibres or damage to the chemical structure.

Both types of damage cannot be optimally detected by current means or only become apparent after production, to name just two examples. This leads to higher production costs. In an emergency, faulty production can even lead to plant fires. For this reason, and to ensure good production quality, the system is run at 15 m/min below its production capacity for safety reasons. However, 30 m/min or more would be possible. With the sensor-based online monitoring of CarboScreen, the production capacity can be doubled to 30 /min. This would lead to higher production, resulting in lower manufacturing costs and wider use of carbon fibres in mass markets such as automotive, aerospace and wind energy.

For the second time the Innovative Textile and Apparel Show opens its virtual fairground this year. For the second time, Mahlo takes the chance to get in contact with customers from all over the world. Mahlo will present the latest systems and solutions for efficient and high-quality textile production and finishing, with the focus on process optimisation in a digital environment.

In the textile industry, Mahlo is known for high-quality automatic weft straighteners, whether roller or needle straighteners, whether for the finest textiles or heavy fabrics - interested parties can find out about the right equipment for their specific requirements.

Process control systems such as the Patcontrol PCS for pattern recognition and the Famacont PMC for controlling weft and stitch course density also contribute to textile production and finishing. Mahlo wants to support manufacturers in optimising their production processes and thus also the end product in a cost-efficient way.

Solutions for technical textiles and nonwovens
Support in the production process is also available for technical textiles and nonwovens. The focus here is on the Qualiscan QMS quality measurement system. The modularly designed system, which consists of sensors and measuring frames, measures, logs and controls critical parameters such as basis weight, moisture or layer thickness across the entire fabric width. Depending on the application and task, different measuring methods are used for this purpose.

Paper Converting Machine Company (PCMC) has announced its industry-leading wet wipes folding machines the Rx200 and Mako Clipper are now available with high-content alcohol, measuring as much as 70 percent.

Previously, PCMC wet wipes machines operated with less than 20 percent alcohol, producing disinfectant wipes for personal, home, industrial and automotive use. However, the COVID-19 pandemic has created a spike in demand for sanitizing wipes that contain at least 70 percent alcohol, the key component in killing or deactivating viruses.

To help manufacturers meet the increased demand, PCMC redesigned its Rx200 and Mako Clipper to safely operate with high-content alcohol. The new designs feature increased air exchange for better ventilation and additional sensors to eliminate the risk of flash points and fires. The machines also include IDS 150/300 integrated dual stackers and a redesigned Mako saw to meet more stringent regulations and higher machine performance expectations.

New blade edge and integrity sensors save operators time and money

Paper Converting Machine Company (PCMC), part of Barry-Wehmiller, has announced that the Xcut saw, its newest tissue saw, now includes innovative sensors that monitor saw blade condition. This new technology tracks the edge of the blade and monitors it for the earliest indications of a blade crash.

The blade edge sensor monitors the current diameter of the blade, and automatically adjusts functions like grinder depth and other blade wear compensations. This sensor also gathers data that can be used to study the blade wear rate. Using a blade diameter measurement, which is performed in real time, along with the number of cuts and grind parameters, the PLC can fit a regression function to this data to inform the operator of the estimated number of cuts remaining on the blade for a given product diameter. Understanding blade wear allows operators to more easily optimize the process and preplan for blade changes.

In addition, the Xcut saw features a fiber optic blade integrity sensor. A blade with a chip or portion of the edge missing will produce cuts with streaks or shreds that are unacceptable to most producers. The defect is usually detected only after a significant amount of product is cut and potentially passed on to the packaging operations. The material expense, lost production and time it takes to purge the product from the system are costly. During normal operation, the sensor is covered by the blade. If at any point the sensor becomes uncovered, it puts the saw into emergency stop mode. The sensor would only become uncovered if the blade crashes or breaks. The emergency stop prevents further damage to the saw caused by slinging blade fragments.

“The blade edge technologies, along with the many other innovations on the Xcut, make the saw easier to maintain and safer to operate,” said Jonathon Zahn, PCMC’s Lead Mechanical Engineer for the Xcut. “Ease of use and operator safety are always goals when developing new products at PCMC.”

"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.
