• zwissTEX adds zwissCLEAN MASK BASIC to the zwissCLEAN® antiviral and antibacterial range

zwissTEX is adding a BASIC mask to the zwissCLEAN® range which is particularly suitable when a mask is to be worn over a longer period of time - whether for school, concerts, trade fair visits or air travel. "The special feature of our zwissCLEAN MASK BASIC is that it can be worn for up to 12 hours without any problems due to the breathable material", says Maximilian Schönfließ - Business Development Manager of zwissTEX. "With it even sleeping is possible. And unlike disposable masks it can be washed up to 10 times at 30 degrees. Disposal by type is also possible".

With zwissCLEAN® masks, zwissTEX is a pioneer among manufacturers of antiviral and antibacterial oronasal masks. Unlike conventional models they actively and highly effectively eliminate viruses and bacteria thanks to the latest textile technologies. This is made possible by an environmentally friendly finishing that foregoes the use of silver and zinc. "The formula physically interrupts the cell membrane of the viruses and bacteria - so no development of resistance is possible. In this way 99.9 percent of viruses and bacteria are eliminated within a very short time," says Schönfließ.

The zwissCLEAN MASK COMFORT is recommended for daily protection at shopping, on public transport, at business appointments or similar events. It consists of a three-layer structure and combines efficient antiviral protection with long-term wearing comfort. The outer material and the integrated fleece promote protection against viruses and bacteria. The lower material made of organic cotton guarantees a lasting pleasant feeling on the skin. The mask can be washed up to 30 times, thus replacing up to 210 disposable masks and saving resources sustainably.

The zwissCLEAN® range is being continuously expanded. "In addition to mask production we plan to manufacture antiviral and antibacterial gloves," says Schönfließ. "The test phase is already underway and we will start production of the gloves in the coming weeks.

New online tool provides users with fast, secure access to manuals and training materials

Paper Converting Machine Company (PCMC), part of Barry-Wehmiller, has launched an innovative online documentation portal, designed to elevate customer trust and ensure the safe operation, maintenance and ownership of all PCMC machines.

Known as myPCMC, the tool provides customers with instant access to parts manuals, controls manuals, operator instruction manuals and training materials for their specific machines. After entering a personalized login, users can easily navigate to the needed documentation, which is organized by location and machine. To access myPCMC, all users need is a web-enabled device (computer, tablet or smartphone) and an internet connection.

With myPCMC, customers are guaranteed to be viewing and using the latest version of their machine documentation — PCMC can easily upload revised files and notify customers about changes within minutes. Furthermore, this new online portal not only enhances today’s machine documentation, but myPCMC also provides a platform for future documentation needs, making it possible to share videos, 3D machine models and other interactive files.

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.”

Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, today announces that Dyneema® is driving the performance of Team Sunweb’s protective cycling jerseys in the 2020 Tour de France. Together with its partners, Team Sunweb and Craft Sportswear, DSM has helped to deliver a jersey that, when combined with a protective baselayer, offers cyclists effective abrasion protection at speeds up to 60km/h, while also reducing the severity of open wounds at even higher speeds. In this way, DSM underlines its commitment to protect people and the environment they live in.

Professional cycling places its participants in considerable danger; in recent years, the Tour de France has averaged 1.5 crashes per stage, while crashes in one-day classics are even more frequent. Cycling jerseys can support riders by enabling protection for a large portion of the body, while allowing for moisture transport to the surface and offering low thermal resistance. However, cycling jerseys made with conventional materials offer limited protective performance.

To address these needs and enable a safer riding experience, DSM has teamed up with Craft Sportswear and Team Sunweb to develop a cycling jersey that offers much-needed increases in abrasion resistance without compromising the comfort or low weight that cyclists demand. The new jersey is the latest protective cycling apparel solution, following the launch of the protective bib shorts (2015) and the protective baselayer (2019). The jersey will be worn for the first time by Team Sunweb in this year’s Tour de France. When combined with the protective baselayer, the new jersey offers complete protection against abrasions up to 60km/h, a speed below which professional cyclists spend 95% of race time in a typical stage.

Dyneema® has been used to protect workers in high-stake industries for more than 30 years – and the expansion into fabrics means both professional and recreational cyclists can enjoy the intrinsic performance capabilities of Dyneema® in their protective garments without sacrificing wearer comfort.

“Being 15 times stronger than steel on a weight for weight basis, Dyneema® fiber offers an excellent solution to increasing the abrasion resistance of a fabric, reducing the severity of road rash in case of a crash, without compromising the rider weight or comfort,” states Piet Rooijakkers, Head of R&D Team Sunweb “What’s more, the new jersey can form part of a modular protection solution, where riders can easily take off or put on layers according to race and weather conditions. In this way, the new jersey will support our riders significantly in the Tour de France and beyond.”

“The new cycling jersey with Dyneema® will make a real difference to cyclists facing the dangers of professional competition, and help ensure the health of both people and the environment,” states Wilfrid Gambade, President DSM Protective Materials. “The jersey is physical proof of the great achievements collaboration with expert partners can deliver. Moving forward, we will work with Craft and Team Sunweb to integrate bio-based Dyneema® fibers into protective cycling jerseys – contributing even further to a safe and healthy world!”

In line with its commitment to protect people and the environment they live in, DSM introduced the world’s first-ever bio-based HMPE fiber in May 2020. Bio-based Dyneema® fiber offers the same exact performance as conventional Dyneema® with a carbon footprint that is 90% lower than generic HMPE. The continued partnership between DSM, Craft and Team Sunweb will not only provide innovative, lightweight solutions for cyclists, but also environmentally sustainable alternatives that contribute to a circular economy.

• Kettelhack GmbH – a German leader in the dyeing and finishing of monochrome fabrics for high-quality and durable workwear and bed linen – has this year retired its existing Monforts sanforizing line after 35 years of daily service, replacing it with a new one.

The first line was installed in 1985 during a decisive time for the company.

Taking the helm in the early 1980s, Jan Kettelhack – the current CEO, owner and great grandson of Heinrich Kettelhack who founded the company back in 1874 – made a number of decisions that have secured its success over the following decades.

In 1982 Kettelhack had to vacate its existing plant in the city of Rheine due to urban development restrictions and despite a general sense of crisis in the European textile industry at that time, opted to relocate and build a new highly automated plant that was not reliant on mechanical and personnel-intensive processes. This was aligned with a greater focus on competitive international sales.

From 1986, the company’s proficiency as a specialist in solid-colour textiles led to workwear textiles becoming a bedrock of the business. Continuous investments in machinery and technical equipment have resulted in a fully integrated and rationalised single source site dedicated solely to what the company does best – the expert dyeing and finishing of textiles.

Crucial process steps

These stages in the textile value-added chain, Jan Kettelhack has observed, are crucial to the quality of a final product in workwear – whether it stands the test in everyday use, how comfortable it is, and how many washes it can withstand.

Central to this is the sanforizing process, which pre-shrinks a fabric by compressing it prior to washing. This limits any residual or further shrinkage in a made-up finished garment to less than 1%, to ensure perfect comfort and fit over an extended lifetime.

“We certainly can’t complain about the performance of the old Monfortex sanforizing line which gave us so many uninterrupted years of service, but certain spare parts for it were becoming increasingly hard to source, the control unit was becoming a little unstable and we couldn’t risk potential interruptions to our production schedule,” says Kettelhack plant manager Hendrik Pleimann. “In many ways, the new Monfortex sanforizer is much the same as the old one in terms of its mechanical reliability and robust construction, but of course today’s drives are much more efficient, and when it comes to the automation features and control units – and the data we can generate and analyse for increasing efficiency – that’s a whole new world.”

Qualitex 800

The two-metres-wide Monfortex line benefits from the latest Qualitex 800 control system which allows all parameters to be easily automated via the 24-inch colour touchscreen, including production speed, control of all fabric feed devices, rotation spray or steaming cylinder options, the width of the stretching field and the rubber belt pressure.

The integrated Compactomat system allows a continuous indication and control of the shrinkage values and the temperatures of the shrinking cylinder and felt calender. Up to 10,000 separate process parameter records can be generated and stored by the data manager.

Full line management can be optimised via the batch-specific calculation of all process material consumption and water and electricity use, with any standstill times analysed and immediately corrected for the future.

Any further assistance required is available via Monforts Teleservice, with direct connection to technicians and virtual access to machine analysis.

Professional

Commissioning of the new Monfortex line at Kettelhack commenced in January and it was fully operational in a relatively short time.

“This was a very professional installation provided by the Monforts team with whom we have a very good relationship dating back many years, and everyone knew what was required from both sides,” says Mr Pleimann. “Our operators have found the new line very user friendly and we are very pleased with how everything proceeded so smoothly. An unexpected benefit is that the new line is also a lot quieter, of course, which is something our operatives are appreciating.”

Key features of the Monfortex line are the proven fabric preparation, weft straightening and spreading units, prior to the compressive shrinkage machine with a 750mm shrinking cylinder, and a felt calender equipped with 2,000mm diameter drying cylinder. The line also features an integrated automatic grinding unit.

Customer service

Kettelhack is processing primarily cotton and polyester woven fabrics, with lyocell becoming increasingly popular in workwear for its softness and comfort.

As part of its customer service, the company stocks more than a million metres of grey fabric and at least 1.2 million metres of finished and rolled standard fabric in its warehouse at any one time, with a further 750,000 metres permanently in production.

While a significant cost, this commitment ensures Kettelhack customers can be fully flexible and rely on it as a partner.

“As a family-run company with around a hundred employees, Kettelhack operates very differently to bigger businesses which have to constantly consider their immediate quarterly profits,” Mr Pleimann concludes. “The thinking at Kettelhack is in terms of the next twenty years and ensuring that the business will be just as successful for the next generation as it is today. We also have a very flat organisational structure in which everyone is involved and takes an active part, which makes it a very nice place to work.”

August, 18 2020 Rieter has placed a bond of CHF 75 million with a term of four years and a coupon of 1.55%. This serves to partially refinance the existing bond of CHF 100 million, which is due on September 29, 2020. The bond was issued by Commerzbank. The bond will be listed on the SIX Swiss Exchange.

• Rieter protects its innovations and products with patents and registered designs.

The company takes consistent action against patent and design infringements. In mid-July 2020, in a legal dispute, the Shanghai Intellectual Property Court of the People’s Republic of China ruled in favor of Rieter Ingolstadt GmbH (Germany).

Rieter machines stand for outstanding quality, high operational safety, excellent performance and user-friendliness as well as unique design. In order to benefit from these characteristics, competitors copy the successful Rieter machine concepts and even adopt the coveted Rieter design.

Rieter protects its innovations by means of patents and registered designs. The company takes consistent action against companies that infringe Rieter patents or designs and copy products or machines. In 2018, Rieter registered design infringe-ments by Shenyang Hongda Textile Machinery Co., Ltd. in relation to double-head draw frames, and decided to file a lawsuit against the Chinese company.

In mid-July 2020, the Shanghai Intellectual Property Court of the People’s Republic of China determined that the double-head draw frames JWF1316 and JWF1316T of Shenyang Hongda Textile Machinery Co., Ltd. are similar to and fall within the scope of protection of the design patent concerned. The defendant Shenyang Hongda Textile Machinery Co., Ltd. was sentenced to compensate the plaintiff Rieter Ingolstadt GmbH for financial losses and expenses.

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.

• Protective masks, everyday masks, disinfecting wipes and surgical gowns are goods in demand in times of corona.
• In their manufacture, textile machines are at the beginning of the production chain.

The production of the textile raw material is the first step of the usually multi-stage production processes. Members of the VDMA Textile Machinery Association are at the beginning of this technological chain.

The production of protective masks starts with the manufacture of the filter material, which for surgical masks as well as FFP2 and FFP3 respirator masks consists of fine-pored nonwoven fabric to intercept coronaviruses. In addition to the systems, machines and components used for this purpose, measurement and control technology ensures the highest quality of important parameters such as basis weight and air permeability. Nonwovens used for respiratory masks have to meet the same high-quality requirements as the masks – to ensure the protection of the mask wearer.

Members of the VDMA Textile Machinery Association have reacted to the new market requirements in a very short time and developed new technologies for knitted, warp knitted as well as woven mouth and nose masks that can be produced without the need for sewing. For surgical masks, FFP2 respirators and social distancing masks, a wide variety of other materials and combinations of materials are used (nonwovens, woven fabrics, knitted or warp knitted fabrics and laminates thereof). Elastic bands are required to wear the masks and several association members provide technologies for their production.

Materials for masks can be treated with textile chemicals to make them antiviral and antibacterial. For this purpose, the VDMA member companies offer application systems which apply the corresponding chemicals to fabric webs. As already mentioned, quality assurance is extremely important for medical products. For this purpose, member companies of the VDMA offer software systems with which each mask can be traced through the entire production process.

VDMA members also offer solutions for the assembly of respirator masks, some of which were developed at short notice. These solutions enable respirators to be produced that meet the relevant standards and the highest quality requirements of customers and market surveillance. This applies to systems for the production of surgical masks and FFP respirators. At the end of the production chain, machines are used to pack masks in single or multiple packs.

In pandemic times, the demand for protective gowns (so-called surgical gowns) also increases. The same applies to disinfecting wipes. For these textile products, too, VDMA members manufacture tailor-made machines for production through to packaging. The quality of the products is ensured by means of measurement and control technology.

In the wake of the corona crisis, VDMA Textile Machinery has launched a new series of web events called "Textile Machinery Webtalk". Here, experts from up to four VDMA member companies present their innovative technologies on a specific topic in a maximum of 90 minutes and are available to answer questions from participants. The presentations are held in English. Participation in the web events is free of charge.
Topics of the first two webtalks were:
"Technologies for the production of melt-blown nonwovens for respiratory protection masks (FFP masks and surgical masks)."
"Technologies for the production of respiratory protection masks (FFP masks and surgical masks)."

The format is well received. Around 180 people from more than 30 countries took part in the first two webtalks. With this format, the VDMA reaches both textile and nonwovens manufacturers who already manufacture these products and companies that want to invest in new business areas.

The next webtalk will take place on 23 July 2020 from 14.00 to 16.00 (CEST) on the current topic "Technology solutions to produce fully-fashioned community face masks." Experts from KARL MAYER, STOLL by KARL MAYER and Jakob Müller will be presenting their technologies for producing everyday textile masks to an international expert audience.
