From the Sector

In view of the easing of pandemic restriction policies in China, the Spring Editions of Intertextile Shanghai Apparel Fabrics, Yarn Expo and Intertextile Shanghai Home Textiles have been moved to the new timeslot of 28 – 30 March 2023. This will allow both local and international fairgoers more time to prepare for their participation, with a higher industry turnout now expected at the three fairs. The fairs will still be located at the National Exhibition and Convention Center in Shanghai where they were originally due to be held from 8 – 10 March.

Discussing the change of dates, Ms Wilmet Shea, Deputy General Manager of Messe Frankfurt (HK) Ltd explained: “After talking to our stakeholders, we believe adjusting the spring show dates to the end of March is the right move. It provides enough time for exhibitors and visitors from local and abroad to plan for the fairs and capitalise on the ample international business opportunities brought by the reopening of China’s border.”

For the design of the special exhibition, all Trevira CS customers were invited to submit their latest Trevira CS products, distinguished by additional functions and/or special features, to the annual Trevira CS Fabric Competition. 227 products from 50 customers were submitted, from which about 150 were selected for the special exhibition. Several thousand meters of yarn will also be used in this year's special show.

Fibres, fabrics, epoxy resins and adhesives from Sicomin have been used by Grand Largue Composites (GLC) to construct the first Class40 racing yacht to feature a significant quantity of flax-fibre reinforcements.
The yacht, called Crosscall, won the Class40 World Championships in June 2022 and is a prototype of the new Lift V2 design by Marc Lombard, one of the leading naval architects in this field.

Class40 is one of the most competitive fleets in yacht racing. The hulls of Class40 yachts must be light in weight, strong and stiff, and durable in the most extreme of conditions. Furthermore, to keep costs down, they cannot be reinforced with carbon fibres. The quality and reliability of the resins used for the infusion and lamination of the hulls are therefore of paramount importance.

Crosscall's cockpit was designed to be effectively non-structural, with the mainsheet, which can generate huge shock loads, supported separately. This would allow the cockpit to be made from a hybrid biaxial fabric comprising 50% flax fibres. Other parts of the boat that incorporate flax fibre include the tunnel, the engine cover, the ballast tanks and the cap. The rest of the boat is reinforced with 100% glass-fibre fabrics.

To help it realise this ambitious design, GLC, an infusion specialist, turned to its long-time material supplier, Sicomin. The hull was moulded and infused in one piece and the deck – including the hybrid flax-fibre cockpit – was also infused as a single part. The internal structure was then laminated into the hull by hand before the hull and deck were finally bonded together.

The infusion resin selected was Sicomin’s SR 1710, a high-modulus structural epoxy. Designed specifically for use in infusion and injection processes, it has exceptionally low viscosity and its low-reactivity hardener makes it suitable for the production of large parts. Composites components made from SR 1710 possess high interlaminar shear-strength and the resin retains its mechanical properties in wet environments.

Sicomin’s low-toxicity SR 8200 was used to laminate the internal structures onto the skin of the hull. Ideal for hand laminating, this system includes a choice of hardeners with a wide range of reactivities, which makes it equally suitable for making large or small parts. The hull and deck were joined together with Sicomin’s Isobond SR 7100, which demonstrates high fatigue strength and is very resistant to microcracking.

An epoxy bonding primer – called Undercoat EP 215 HB+ and supplied by Sicomin’s sister company, Map Yachting – was applied to the moulds first to make demoulding easier. It also serves as an undercoat in the polyurethane exterior paint system that is used instead of gelcoat to protect the epoxy hull from UV damage.

Since the launch of Crosscall, GLC has started building a second Lift V2 Class40 and a third one is now planned, both for which Sicomin will supply the materials.

• made out of recycled PET flakes and recyclable again
• suited for finishing recycled yarns and fabrics
• moisture management in sports and active wear

For the sustainable use of resources, the CHT Group has developed the product ARRISTAN rAIR, according to the principles of the circular economy. Here, plastic waste is converted into a valuable textile finishing product to achieve, for example, optimal moisture management in sports and active wear. Other areas of application include socks and tights in the clothing sector, filtration media and nonwovens in the technical textiles sector, and pillows and curtains in home textiles.

Since ARRISTAN rAIR is made out of recycled PET flakes, it is suited for finishing recycled yarns and fabrics which are subsequently recyclable again.

The hydrophilizing agent ARRISTAN rAIR is characterized by its fast-drying properties in combination with excellent soil release and thermoregulation. It therefore offers, especially in the field of functional textiles, optimal functionalities for high-quality and durable sportswear.

The Gleaming line by the Marchi & Fildi Group includes a wide range of metalloplastic yarns for the most varied of uses. Reflex, the new range of reflective yarns, will join the line.

In addition to uses in the worlds of fashion and furnishings, for fancy yarns, decoration and accessories, an important application for the Gleaming collection is in the sector of technical clothing with high-visibility features.

Reflex, used for the production of fabrics and tapes, able to reflect the light and ensure good visibility for people wearing them in low-light situations, is augmented by new colour shades in addition to the traditional greys.

The innovative reflective yarns in white, black, and light and dark multicolours offer new possibilities for:

• tapes, external labels and accessories;
• technical fabrics for work clothing with specific safety standards;
• uniforms, sports clothing and accessories;
• hosiery, gloves, bibs and hats for night use, for winter clothing and for northern markets.

The latest addition to the range, with an important functionality, is the Reflex stretch yarn, which, apart from in the sectors described above, also finds application in flat bed or circular knitting and sewing. Its composition makes it softer and more versatile in comparison to traditional reflectives.

The Gleaming line represents a completion of the range of yarns produced by the Marchi & Fildi Group. The yarns are available in various thicknesses, widths and types in both metallised and transparent versions, and iridescent, reflective and phosphorescent effects. Also articles are included with particular features of resistance to chemical and dyeing treatments.

Amongst the most recent innovations is the line of metalloplastic yarns in 100% polyester obtained from post-consumer recycling with GRS (Global Recycle Standard) certification.

At the recent CAMX 2022 Composites and Advanced Materials Expo in Anaheim, California, The Heat Sealing Module – HSM from Zünd was recognized with an Unsurpassed Innovation Award. The HSM significantly facilitates the processing and handling of dry fiber materials with thermoplastic content. This new tool is Zünd’s answer to a demand in the composites industry for wider-spread use and easier processing of these types of materials.

The American Composites Manufacturing Association, ACMA, proclaimed the Heat Sealing Module – HSM the winner of the ACE Award for Unsurpassed Innovation in the “Manufacturing: Equipment and Tooling” category. This award is presented annually to equipment, tooling, a production aid, or software designed to improve manufacturing production, environmental sustainability, or product quality and performance in composites manufacturing.

During processing, dry fiber materials are prone to fraying along the edges. Using hot air, the HSM seals the fabric along the cut path in advance of the Zünd Power Rotary Tool – PRT cutting it. Because of this sealing process, the cut can then be performed at full speed, in any direction, and produces both higher-quality parts and greater production efficiencies.

The HSM helps create clean, sealed edges when cutting fiber-reinforced thermoplastic composites. It benefits not only the cutting process itself, but other production processes downstream. Cutting this way leaves behind no loose or uncut fibers and maintains a clean cutting surface and uncontaminated production environment. At the same time, it ensures that cut parts maintain their shape, and this increased stability makes them much easier to handle, especially in fully automated production workflows.

• 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.

Electronically conductive fibres are already in use in smart textiles, but in a recently published research article, ionically conductive fibres have proven to be of increasing interest. The so-called ionofibres achieve higher flexibility and durability and match the type of conduction our body uses. In the future, they may be used for such items as textile batteries, textile displays, and textile muscles.

The research project is being carried out by doctoral student Claude Huniade at the University of Borås and is a track within a larger project, Weafing, the goal of which is to develop novel, unprecedented garments for haptic stimulation comprising flexible and wearable textile actuators and sensors.

In Claude Huniade’s project, the goal is to produce conductive yarns without conductive metals.
"My research is about producing electrically conductive textile fibres, and ultimately yarns, by coating non-metals sustainably on commercial yarns. The biggest challenge is in the balance between keeping the textile properties and adding the conductive feature," said Claude Huniade.

Currenty, the uniqueness of his research leans towards the strategies employed when coating. These strategies expand to the processes and the materials used.

Uses ionic liquid
One of the tracks he investigates is about a new kind of material as textile coating, ionic liquids in combination with commercial textile fibres. Just like salt water, they conduct electricity but without water. Ionic liquid is a more stable electrolyte than salt water as nothing evaporates.

"The processable aspect is an important requirement since textile manufacturing can be harsh on textile fibres, especially when upscaling their use. The fibres can also be manufactured into woven or knitted without damaging them mechanically while retaining their conductivity. Surprisingly, they were even smoother to process into fabrics than the commercial yarns they are made from," explained Claude Huniade.

Ionofibres could be used as sensors since ionic liquids are sensitive to their environment. For example, humidity change can be sensed by the ionofibers, but also any stretch or pressure they are subjected to.

"Ionofibres could truly shine when they are combined with other materials or devices that require electrolytes. Ionofibres enable certain phenomena currently limited to happen in liquids to be feasible in air in a lightweight fashion. The applications are multiple and unique, for example for textile batteries, textile displays or textile muscles," said Claude Huniade.

Needs further research
Yet more research is needed to combine the ionofibres with other functional fibres and to produce the unique textile devices.

How do they stand out compared to common electronically conductive fibres?
"In comparison to electronically conductive fibres, ionofibers are different in how they conduct electricity. They are less conductive, but they bring other properties that electronically conductive fibers often lack. Ionofibres achieve higher flexibility and durability and match the type of conduction that our body uses. They actually match better than electronically conductive fibres with how electricity is present in nature," he concluded.

IFFAC (Impact Fund for African Creatives) has revealed plans which will revolutionise West African textile and garment production at one stroke. The fund is converting a partially disused textile mill in the region into a hi-tech centre for processing local cotton and recycling waste fabric, to produce both fabric for further processing and new clothes. The mill will be equipped with modern equipment, all sustainably powered by hydroelectricity from the nearby Volta Dam.

West Africa grows about 6% of the world’s cotton but only a tiny fraction of that crop is processed on the continent, the vast majority being shipped thousands of miles to Asia before being shipped back again as finished or part-finished fabrics. The mill project will end the continent’s reliance on such an unsustainable practice with all the obvious financial and environmental benefits.

As well as producing fabric from sustainably grown virgin cotton, a joint venture with Shandong-based WOL Textiles Ltd., a privately owned plant that has long supplied the African market, the mill will be home to a state-of-the-art shredding and recycling facility, a joint venture between IFFAC and the Dutch Circularity B.V. CEO Han Hamers of Circularity B.V. in The Netherlands, has been involved in the production of 100% circular knit and woven articles.

The mill project is expected to create over a thousand jobs. The surrounding area already boasts a significant number of experienced textile workers ready to be retrained on the new equipment. While the majority of the products created will be sold within the region, all processes will confirm to new EU Supply Chain Law to allow for the possibility of export.  

Output is forecast at six million pieces of finished clothing and twenty-five million metres of spun and woven cloth per year. In total, thirty million US$ of investment will be made in the site with operations ready to begin next year (2023).
