From the Sector

Freudenberg Performance Materials (Freudenberg) is widening its product range of technical packaging textiles. Evolon® ESD protects automotive and industrial parts with electronic components from electrostatic discharge. This includes trim lines, dashboards, mirrors, steering wheels, etc.

The ESD (ElectroStatic Discharge) feature of the new Evolon® technical packing textile provides permanent electrostatic discharging protection and the fabric’s surface resistivity can be customized. This eliminates ESD damage to electronic components during transport because electrostatic charging due to movement and friction is safely prevented. As this kind of damage cannot be detected with the naked eye, Evolon® ESD helps to avoid failures which can occur after the final product is assembled and released. Manufacturers benefit from fewer complaints and warranty costs, as well as better end customer satisfaction.

Further protection feature
Unlike conventional ESD packaging solutions, Evolon® ESD also protects parts surfaces by avoiding micro-scratches or lint contamination. By using Evolon® reusable packaging to transport parts with highly-sensitive surfaces, customers reduce the number of damaged parts and the reject rate.

Additional benefits
Evolon® microfilament textiles are also extremely strong and are available in different weights to meet a wide range of requirements – from lightweight to heavy-duty. They can be used to pack and transport very heavy parts without damage. In addition, Evolon® fabrics are durable, and contain up to 85% recycled PET.

The American subsidiary of the Swiss Oerlikon Group, Oerlikon Textile Inc., is expanding and moving into new, modern premises tailored to future needs just a few kilometers away from its previous location in Charlotte, North Carolina. A new service center for the polymer processing industry will be created on approximately 4500 m² of office and commercial space latest by the middle of this year.
Oerlikon expands service offering for customers in the USA

"We are the preferred technology partner in the field of man-made fiber production in the USA and not only want to remain so, but also to further expand our services for our customers. However, the previous premises no longer offered any opportunities for expansion," explains Chip Hartzog, President of Oerlikon Textile Inc., the logical step.

All processes will be optimized in the new buildings. Incoming goods, warehouse and dispatch will be merged, inventory control will be strengthened. On top, the range of services in the repair area will be expanded. "In addition to our services in the area of filament and carpet yarn systems, we will also be able to offer our customers repair services for staple fiber components such as crimpers or nonwoven systems in the future," says Chip Hartzog. This will further strengthen the market position for the Oerlikon Barmag, Oerlikon Neumag and Oerlikon Nonwoven brands.

Oerlikon Textile Inc. has been active in the manmade fibers business in the USA for over 55 years. In addition to the sale of Staple Fiber, BCF, IDY, POY, FDY and texturing plants, the product portfolio also includes upgrades and modernization of old plants, service and training offers as well as repair services and spare parts supplies.

Over the past three years, a dedicated AI development team at BTMA member Shelton Vision has been developing tailored machine learning solutions for the textiles industry.

The aim has been to elevate the detection process and the accuracy of naming and grading subtle defects in textiles, in real time within production environments.

“Big Data ‘off-the-shelf’ systems such as those behind technolgies like facial recognition and Google Maps involve reading many thousands of single images each second and simply take too long to accumulate sufficient data for what’s required in this specific case,” says Shelton Vision CEO and Managing Director Mark Shelton. “A feature of the textile industry is that in many sectors, the product range changes several times within a year and it is not uncommon to have to inspect hundreds, if not thousands of different styles in a year based on precise settings.”

In terms of defect types, he adds, there may typically be over 100 that need to be accurately detected, classified (named) and graded in real time.

“Added to this is the need to ‘filter out’ the random occurrence of ‘non defects’, such as loose threads, lint and dust on the surface – the number of which can be higher than actual defects – and it is clear that a bespoke system is required.”
The development team has consequently established metadata for identifying defect properties, enabling the successful identification of faults from a much smaller number of images.

“The system employs a unique combination of machine learning for automated style training and novel algorithms for defect detection, to provide high quality images for the AI real time defect classification and grading software,” Shelton explains. “Due to the inherent variation in fabric features – raw materials, construction, texture, colour and finishes, as well as the differing product quality standards in value chains and the regional variations in what defects are called – our AI engine uses models built for each individual company or group of companies, or product value chain.”

The AI models are constructed so that the user operatives can populate them with their own data produced by the vision system or by obtaining defect images from another imaging source (eg a mobile phone camera).  

The occurrence of defects is sporadic and many defect types occur infrequently, although when they do, they can have severe consequences. These scenarios re-enforce the need for the AI engine to be quickly set up and able to operate accurately with limited data sets of typically between 30 and 50 good quality images per defect type.

A further feature is a tool enabling the user to periodically ‘clean up’ the AI data during the set up phase. This is used to resolve conflicting data and to correct mis-named images.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

“There is a need for the real time detection of defects that are being created in separate processes, such as printing or coating and for real time automated systems that can accurately determine the defects and their severity and provide a reliable signal for an operative to rectify the issue, This can result in considerable savings.

Prior to Shelton introducing powerful customised machine vision and real time defect classification, the only systems available were those that required manual sifting through vast numbers of images, which included both real defects and ‘non defect’ images. The task was very often overwhelming and did not provide much benefit beyond manual fabric inspection.

Toray Industries, Inc., announced that it has combined nanotechnology and fiber technology to create a cross-shaped polymethyl methacrylate (PMMA) nanopore fiber that efficiently adsorbs pathogenic proteins in the blood.

The company developed this fiber by employing its PMMA hollow fiber membrane spinning technology. Changing the nanopore size on the surface and inside the fiber makes it possible to control the types of protein that this material adsorbs. This could become a fundamental blood purification technology for a range of protein adsorption columns that cause diseases.

The fiber’s cross-shaped cross section has a larger surface area than fibers with round ones. This provides much better contact between the blood and fiber and significantly enhances protein adsorption efficiency.

Toray is the only company to have commercialized a PMMA hollow-fiber membrane artificial kidney for dialysis treatment. Its new nanopore fiber benefits from PMMA’s good protein adsorption and biocompatibility. Using the structural formation of a stereocomplex from two PMMA types entangled spirally during the spinning process to form the fiber shape, Toray made it possible for the fiber itself to develop pores of several to dozens of nanometers. Depending on the pore size, large proteins cannot go inside the pores. If they are too small, they are not trapped. This enables selective adsorption of moderately sized proteins trapped in pores.

The fiber pore sizes are adjustable to the diameters of target proteins for a range of diseases. These include inflammatory proteins in sepsis, autoantibodies in autoimmune diseases, and causative proteins in chronic illnesses. Toray’s technology is thus fundamental to developing disease-causing protein adsorption columns to purify blood.

Toray’s cross-shaped cross section suppresses inter-fiber adhesion, increasing the surface area per volume and enabling highly efficient protein adsorption. For blood purification applications, higher capacity adsorption columns increase blood removal amounts from the body, which can be especially stressful for the elderly and children. The new fiber’s highly efficient protein adsorption should contribute to compact, high-performance protein adsorption columns.

• Carbios’ biorecycling and biodegradation technologies internationally recognized by consumers as promising answers to their top environmental concerns
• Carbios’ innovations considered one of the best for solving recycling effectively and achieving a real plastic circularity
• Consumer research including qualitative and quantitative fields was conducted between March and August 2022. The research institute, Strategic Research, conducted 6000 interviews in Europe and USA

Carbios’ biorecycling and biodegradation technologies acclaimed by consumers
During the first research field study, respondents were exposed to Carbios’ biorecycling process; a new enzyme-based biotechnology that enables biological recycling of all types of PET plastic waste (including bottles, packaging and textiles), and pushes the boundaries of recycling in terms of the number of cycles.

The research results demonstrated that European and US respondents find Carbios’ biorecycling technology more unique and innovative than traditional PET recycling (i.e. thermo-mechanical recycling), as well as more relevant in its ability to address their concerns and challenges regarding recycling.

In the second research study, conducted in the US, respondents were also exposed to Carbios’ biodegradation technology: an innovative enzymatic solution by which an enzyme is incorporated into plastics during the production process of bio-sourced PLA plastics (corn, sugar cane). This approach makes the material made from plants 100% compostable at ambient temperatures and degradable like plants with the built-in enzyme biologically breaking the bioplastic down in less than eight weeks without microplastics or toxic residues; creating a fully organic circularity.

Similarly to Carbios’ biorecycling technology, Carbios’ PLA biodegradation innovation caught US respondents’ attention with 64% overall liking it. Additionally, 93% of the respondents sampled described the concept as innovative, unique, easy to understand (49%), and believable (43%). Up to 82% of the most environmentally engaged respondents declared they would definitely buy more products made with Carbios’ fully circular biodegradable bioplastic.

Consumers: No other choice but to make plastic fully circular
The research says 99% of the respondents consider it important to protect the environment, while plastic pollution is now ranked the third most-concerning environmental issues after climate change and ocean pollution.

This awareness brings most of these consumers to be environmentally active when it comes to purchasing goods and sorting. For the US respondents, eco-friendly packaging comes in the fourth place in terms of purchase drivers for packaged goods and 65% of them declare sorting plastic from general waste on a regular basis, which makes plastic the most sorted type of waste.

Nevertheless, for a vast majority of the respondents across geographies, even if they would like to reduce their plastic consumption most of the time there is no suitable alternative that is as convenient, light, and cost-efficient as plastics. Hence in an ideal world, consumers would like all plastic waste in landfills and oceans to be collected, cleaned, reused and recycled.

• Partnership with Spectro Coating Corp. Expands Horizons for the World’s First In-fiber Sustainable Infrared Viscose

CELLIANT® Viscose, which converts body heat into energy, is a combination of nature and performance. It was developed by materials science leader Hologenix®, creators of CELLIANT, a natural blend of IR-generating bioceramics used in textiles, and Kelheim Fibres, a leading manufacturer of viscose specialty fibers. It is the world’s first in-fiber sustainable infrared viscose.  Now Hologenix has partnered with Spectro Coating Corp., the largest vertically integrated flock coating and flock fabric manufacturer in the world, to create the first flocked infrared material with CELLIANT Viscose.

Flocking is an application method in which tiny fibers are piled on to the surface of a textile, creating textures for both decorative and functional purposes. CELLIANT Viscose in a flocked material has many potential applications in the medical field for tapes, bandages, braces and orthopedic products, home textiles and decor, dog beds, clothing, and more.  CELLIANT features natural, ethically sourced minerals, which convert body heat into infrared energy for increased local circulation and cellular oxygenation.  These CELLIANT minerals are then embedded into viscose plant-based fibers. The Viscose fibers are then flocked onto a base material. CELLIANT Viscose provides all the benefits of being a viscose fiber — lightweight, soft, highly breathable, excellent moisture management — as well as the fiber enhancements from CELLIANT infrared technology.

CELLIANT Viscose is the first IR flocked material that Spectro is producing. CELLIANT Viscose also represents a further expansion into sustainable products for Spectro. In addition, Spectro products are made in the USA, as is CELLIANT’s mineral blend.

Monforts has installed and commissioned a new Montex finishing range at the Baltic Works of Halley Stevensons in Dundee, Scotland, to further boost the weatherproofing specialist’s highly flexible operations.

The range, with a working width of two metres, was built at the Montex assembly plant in Austria and consists of a Montex®Coat coating unit in knife execution for paste and foam coating and a Montex 8500 6F stenter.

Founded in 1864, Halley Stevensons has amassed unique technical know-how and manufacturing experience in the art of waxed cotton for weatherproofed fabrics and is able to provide international orders in custom colours and finishes to very low minimum quantities where required. The company exports worldwide and its premium brand customers include Belstaff, Barbours, Filson and J.Crew.

The range has replaced one of the company’s older stenter/coating lines and has already enabled Halley Stevensons to recreate various products with lower coating applications at higher speeds than was previously possible.

Waxed cotton was originally developed by sailors in the early 15th century when Scottish North Sea herring fleets began treating flax sailcloth with fish oils and grease in an attempt to waterproof their sails. Remnants of these sails were used by the sailors as capes to withstand the high winds and sea spray.

By the mid 1850s, sailcloth was being treated with linseed oil, but while initially highly effective, it would yellow and stiffen through weathering over time and eventually lose its waterproofing qualities.

In the years that followed, various treatments were applied to cottons in an attempt to find the most effective weatherproofing solution, and the combination of densely-woven cotton impregnated with a paraffin waxed coating proved most successful. For over 150 years, Halley Stevensons created many different variations of both woven constructions and finishing treatments and now supplies thousands of metres of waxed cotton every year, with each roll produced to custom specifications.

“The beauty of waxed cotton is its durability and longevity,” says Managing Director James Campbell. “The fabrics are breathable, with the wax adjusting to ambient temperatures to be softer and more breathable in warm weather and stiffer and more wind proof in cold conditions.”
While traditional waxes are petroleum or paraffin based, Halley Stevensons has always been comfortable about using a waste product from industry and reusing it to make products that last a lifetime.  

“We are always exploring different finishing techniques and one of our most popular finishes is our hybrid aero – an emulsified blend of waxes,” Campbell says. “This fabric is water repellent but has little wax in the mixture so the handle is much drier to touch than the traditional wet waxes.”

The company has also recently launched a new 100% plant-based wax – Ever Wax Olive – consisting of a blend of olive oil, rape seed and castor bean with comparable water repellence to petroleum and a far better rating than other natural waxes which have come before it.

“The high tradition of skills and fabric innovation imposed by our original guildsmen is still our benchmark standard of honest workmanship today,” Managing Director James Campbell concludes “We use responsibly sourced cotton fabrics and processes that are gentle to the product and low impact to the environment. Our dyeing methods use very low levels of water and our waxes are simply heated up for application and cooled down to store when not in use, meaning no waste discharges. Now, with this new Monforts line, we are also achieving running speeds two-to-three times faster than with the older stenter, combined with less gas usage. It’s proved a great partnership.”

• Monomaterial solution contains renewably-sourced polypropylene from the Bornewables™ portfolio of circular polyolefins
• Trexel employs its proprietary MuCell® technology to deliver a range of lightweighting benefits
• EverMinds™ in action: reuse and design for recycling are focus of value chain collaboration

Borealis and Trexel, an expert in foaming injection and blow moulded parts, announce that they have co-developed a new plastic bottle based on a grade from the Bornewables™ portfolio of polyolefins made using renewable feedstocks derived 100% from waste and residue streams. The lightweight bottle – which will be showcased at the Borealis stand at the K 2022 (from 19 to 26 October 2022 in Düsseldorf) – is reusable and fully recyclable. It boasts a significantly lower overall CO₂ footprint because it is composed of renewably-sourced feedstock and produced in the foaming process.

The Bornewables™ portfolio of circular polyolefins helps reduce the carbon footprint while offering material performance equal to virgin polymers. Using Bornewables grades allows for design freedom and colour flexibility, and helps retain a premium look and feel. The grades – which are commercially available in Europe – help conserve natural resources because they are derived solely from waste and residue streams, for example from used cooking oil. Reusing waste already in circulation instead of fossil fuel-based feedstocks enhances the sustainability of applications made using the Bornewables grades.

The reusable new bottle developed by Borealis and Trexel retains its value over many life cycles thanks to the use of Trexel’s proprietary technology in tandem with Bornewables grades; as a material solution, the new bottle minimises the use of valuable raw materials. Moreover, converters consume less energy in the production process when using the MuCell® technology. The bottle thus helps close the loop on plastics circularity by way of design for recycling, the use of renewable feedstocks, and excellent material performance across multiple life cycles.
