• Formula 1 cars will be cheaper in future

Carbon is the stuff Formula 1 cars are made of, at least the bodywork. But until now, carbon has been expensive. It can be produced more cheaply and efficiently if artificial intelligence monitors the production processes. A camera system combined with artificial intelligence automatically detects defects in the production of carbon fibres. This makes expensive manual inspection of the carbon fibres obsolete and the production price of the carbon fibre can be reduced in the long term.

For this idea, the young engineer Deniz Sinan Yesilyurt received the second prize of the "Digitalisation in Mechanical Engineering" Young Talent Award on 6 December.

Carbon fibres are sought after because of their good properties. They are very light - they weigh up to 50 percent less than aluminium. The combination of low weight and good mechanical properties offers many advantages. Especially in times of the energy transition, lightweight materials like carbon are more relevant than ever before. At the same time, carbon fibres are as resistant to external stresses as metals. However, achieving these good properties of carbon fibres is very complex.

Up to 300 individual fibre strands - bundles of individual fibres - have to be monitored simultaneously during production. If carbon fibres tear, it costs time and money to sort out the damaged fibres. This is just one example of various defects that can occur in the fibres during production.

Therefore, Deniz Sinan Yesilyurt attached a camera to the carbon fibre line that takes pictures of various fibre defects during production and collects them in a database. The artificial intelligence in the camera's information technology system evaluates the fibre defects by assigning the images to predefined reference defects. In doing so, it recognises various fibre defects with a classification accuracy of 99 per cent. The process can also be used in other areas that produce chemical fibres.

Deniz Sinan Yesilyurt received the prize from the German Engineering Federation (VDMA) in Frankfurt am Main, Germany. He is a Bachelor's graduate at the Institut für Textiltechnik (ITA) of RWTH Aachen University. The full title of his bachelor's thesis is: "Development of a Kl-supported process monitoring using machine learning to detect fibre damage in the stabilisation process". The VDMA awarded the prize to a total of four theses from different universities. The prize is awarded for outstanding theses and was offered in Germany, Austria and Switzerland.

Digitalization is a big story in the world of business. It’s all about change, making use of technology to transform attitudes and create new opportunities to grow revenue. At its heart is innovation, with new systems and intelligent use of data. In textiles, the entire value chain is going digital, as evidenced by the commitment of Swiss Textile Machinery Association member firms. Their story – presented here in six ‘chapters’ – spans industry sectors through spinning, weaving, finishing and nonwovens.

Cost savings and more
The process of digitalization in the textile industry today is continuous – faster in some segments than others – but noticeable everywhere. Automation is promising in many areas of finishing and making-up, where initial investments are being made. An example is folding of finished goods, previously a slow manual operation. Now, high-performance automatic folding machines from Swiss company Espritech deliver the potential for cost savings, unlocking new options for positive change at this most labor-intensive stage of production. For manufacturers in low-cost areas, the benefit results from its volume and is a simple financial one. In higher-cost segments, the application of this technology can be part of a completely new business model, taking production closer to the end customer.

Better process, better workplace
Pioneering in the field of digitalization embraces social responsibility along with the introduction of bold new technological innovation. That’s a commitment made by Uster, as it aims to shape future working practices in the textile industry in areas where its systems are applied. In fabric inspection, that means combining the strengths of human capabilities with the performance of Artificial Intelligence. Automatic defect classification with machine learning technology is the next leap in digitalization for fabric manufacturers, following on from automated detection of fabric faults, which is already well established in weaving and finishing mills. This will bring benefits in profitability for the manufacturer – as well as an improved working environment for their operatives, freed from repetitive tasks.

Information, flexible and fast
Access to data is critical in the digitalized world of textiles. It must be flexible, fast and secure, and available to all levels of the company – worldwide. Jakob Muller serves the narrow fabrics industry ideally with a digitalization portal, perfectly developed to provide essential production information. The portal is a browser-based production data acquisition system, with direct access to the machine controls. The system offers unique data monitoring and communication on a global framework. Digitized weave rooms present information 24/7 on desktops at the customer’s plant, as well as on tablets and smartphones remotely.

Making the most of it
Rieter takes advantage of latest digital technology to offer customers a unique experience. Their digital spinning suite helps spinners overcome their daily challenges and manage costs and efficiency more effectively. This all-in-one mill management system connects all the machinery, giving quick access to the right information and a holistic view, from bale to yarn. Users profit from full transparency, and are presented with recommendations based on long-standing experience and know-how. This is digitalization at its most practical, applied to allow spinners to make the most of their installed machinery.

Production, service, training – digital everything
As a solutions provider, Saurer puts digitalization at the core of business, integral to its technology offering to customers. Some latest examples include self-optimization of spinning machines, and a fully automated transport of cylindrical or conical cross-wound packages. These are automatically stored in an internal buffer system, for later feeding to subsequent processes. Of course after-sales service is also digital: the e-shop and machine information hub, together with the web-based training centre, ensure that knowledge is transferred to customers – turning employees into experts.

See the future system today
Autefa Solutions uses the concept of digital twinning, visualizing any real-world concept of a nonwovens line to make it easier for potential customers to grasp the idea. It’s also a big help for training and servicing needs. Most of all they digitalize important parts e.g. of a baling press line with perfectly interconnecting software tools. This is an excellent method for reducing commissioning times. Ordered bale presses reach technical readiness in the form of a digital twin, before they are commissioned in the real world. This typically halves the total time to get the line up and running.
Speaking on behalf of Swiss Textile Machinery Association members, André Imhof, CEO of Autefa Solutions Switzerland AG, says: “Making digitalization our friend opens doors for business model innovations, which is essential for our industry competitiveness. The approach is to digitalize everything that can be digitalized. We won’t stop.”

A broad coalition of industry and labor groups has sent a letter to House and Senate leadership urging support for the Import Security and Fairness Act (included in the broader House America COMPETES Act), which aims to stop China from exploiting the de minimis threshold that allows imports valued under $800 to come into the United States without paying duties and taxes, bypassing U.S. Customs inspections and providing a backdoor to Chinese goods produced with forced labor.

The coalition sent the letter to Senate Majority Leader Charles Schumer (D-NY), Senate Minority Leader Mitch McConnell (R-KY), Speaker of the House Nancy Pelosi (D-CA) and House Minority Leader Kevin McCarthy (R-CA), urging the leaders to strongly support and prioritize the provision in the underlying China bill.

The letter was signed by the following organizations:

• AFL-CIO
• Alliance for American Manufacturing
• Coalition for a Prosperous America
• International Brotherhood of Teamsters
• Narrow Fabrics Institute
• National Council of Textile Organizations
• Service Employees International Union
• U.S. Footwear Manufacturers Association
• U.S. Industrial Fabrics Institute
• United Steelworkers
• Workers United/SEIU

Emphasis on Process, Third-party Validation and Outcome-based Testing

Angelica, one of the nation’s largest healthcare linen providers, now has 23 laundries that have earned the Hygienically Clean Healthcare certification. This is reflective of  their commitment to Best Management Practices (BMPs) in laundering as verified by on-site inspection and their capability to produce hygienically clean textiles as quantified by ongoing microbial testing. Angelica’s locations are throughout the United States, and the laundries now carrying the certification are located in Phoenix, AZ; Colton, Fresno, Los Angeles, Orange, Pittsburg, Pomona, and Sacramento, CA; Holly Hill and Safety Harbor, FL; Rockmart, GA; Chicago, IL; Somerville and Worcester, MA; Durham, NC; Henderson, NV; Batavia, NY; Lorain, OH; Pawtucket, RI; Columbia, SC; Ooltewah, TN; and Dallas and Houston, TX.

The Hygienically Clean Healthcare certification confirms the organization’s continuing dedication to infection prevention, compliance with recognized industry standards and processing healthcare textiles using BMPs as described in its quality assurance documentation, a focal point for Hygienically Clean inspectors’ evaluation. The independent, third-party inspection must also confirm essential evidence that

• Employees are properly trained and protected
• Managers understand regulatory requirements
• OSHA-compliant
• Physical plant operates effectively

To achieve certification initially, laundries pass three rounds of outcome-based microbial testing, indicating that their processes are producing Hygienically Clean Healthcare textiles and diminished presence of yeast, mold and harmful bacteria. They also must pass a facility inspection. To maintain their certification, they must pass quarterly testing to ensure that as laundry conditions change, such as water quality, textile fabric composition and wash chemistry, laundered product quality is consistently maintained. Re-inspection occurs every two to three years.

This process eliminates subjectivity by focusing on outcomes and results that verify textiles cleaned in these facilities meet appropriate hygienically clean standards and BMPs for hospitals, surgery centers, medical offices, nursing homes and other medical facilities.
Hygienically Clean Healthcare certification acknowledges laundries’ effectiveness in protecting healthcare operations by verifying quality control procedures in linen, uniform and facility services operations related to the handling of textiles containing blood and other potentially infectious materials.

Certified laundries use processes, chemicals and BMPs acknowledged by the federal Centers for Disease Control and Prevention (CDC), Centers for Medicare and Medicaid Services, Association for the Advancement of Medical Instrumentation, American National Standards Institute and others. Introduced in 2012, Hygienically Clean Healthcare brought to North America the international cleanliness standards for healthcare linens and garments used worldwide by the Certification Association for Professional Textile Services and the European Committee for Standardization.

Objective experts in epidemiology, infection control, nursing and other healthcare professions work with Hygienically Clean launderers to ensure the certification continues to enforce the highest standards for producing clean healthcare textiles.

“Congratulations to Angelica on their certifications,” said Joseph Ricci, TRSA president and CEO. “This achievement proves their commitment to infection prevention and that their laundries take every step possible to prevent human illness.”
