• Patented SILASTIC™ LCF 9600 M Textile Printing Ink Base addresses growing demand for improved performance in textile applications

With the continued global growth of the apparel market, the use of polyester, nylon and blends of these materials with elastane is also on the rise, especially in sportswear and loungewear. To support this higher demand for synthetic textiles, Dow is launching a patented silicone ink – SILASTIC™ LCF 9600 M Textile Printing Ink Base – that can be used for printing on synthetic and cotton fabrics, particularly highly elastic garments.

The increased use of synthetic yarns in recent years has resulted in greater performance requirements on ink chemistries such as durability, elongation and ease of use in highly elastic sportwear. To address these needs, Dow leveraged the exceptional benefits of silicone ink bases with products such as SILASTIC™ LCF 9600 Textile Printing Ink Base and SILASTIC™ 9601 Textile Printing Ink Base.

Designed for an increased matte effect and improved hand feel, the patented SILASTIC™ LCF 9600 M offers excellent wash durability, high elongation, very soft low tack touch and avoids the “orange peel effect” on cotton substrates. Additionally, SILASTIC™ LCF 9600 M enables safer textile development with its ability to be formulated without the use of PVC, phthalates, solvents, organotins and formaldehyde.

Hologenix, creators of CELLIANT®, and global textile solutions provider UNIFI®, makers of REPREVE®, have announced their partnership to introduce CELLIANT® with REPREVE®. CELLIANT with REPREVE has the infrared properties of science-backed CELLIANT infrared technology and the sustainable footprint of REPREVE, a brand of recycled fiber.

CELLIANT is a blend of IR-generating bioceramic minerals, which, when embedded into textiles, allows them to convert body heat into infrared energy, returning it to the body and temporarily increasing local circulation and cellular oxygenation. This aids significantly in muscle recovery, increases endurance, and improves overall performance in healthy individuals, among other benefits.

REPREVE recycled performance fiber consists of high-quality fibers made from 100% recycled materials, including post-consumer plastic bottles and pre-consumer waste. It is also certified and traceable with U TRUST® verification and FiberPrint™ technology, to back up customers' recycled claims. Compared to virgin fiber, REPREVE helps to offset the use of petroleum, emitting fewer greenhouse gasses and conserving water and energy in the process.

CELLIANT with REPREVE’s official preferred North America knitting partner is Beverly Knits, one of the largest circular knitters in the US, developing fabric for all markets including intimate apparel, activewear, outdoor products, mattress and bedding, automotive, industrial and medical. Beverly Knits also operates Creative Dyeing & Finishing, LLC.

Freudenberg Performance Materials (Freudenberg) has concluded a high-volume, multi-year contract with a global automotive tier one supplier to supply high-performance gas diffusion layers for the stacks forming the core of the fuel cell systems produced by the leading automotive supplier. Global target applications are mid-sized and heavy commercial vehicles as well as buses. Freudenberg is supporting the customer’s global fuel cell activities, thereby also accelerating the breakthrough of mass-produced fuel cell stacks.

Fuel cell technology is an important element of a successful energy transition. Gas diffusion layers play a key role in this context: they are indispensable for the functioning of a fuel cell and have a significant impact on the performance of a fuel cell stack.

A fuel cell converts the chemical energy of hydrogen and atmospheric oxygen into electricity. Functionally-optimized gas diffusion layers made of carbon-fiber based nonwoven are installed on both sides of a catalyst-coated membrane positioned in the middle of the fuel cell. The gas diffusion layers distribute hydrogen and oxygen evenly to the membrane and remove the electricity, heat and water generated by the CO₂-free chemical reaction. They also protect the sensitive membrane and are optimized to suit the bipolar plate. A fuel cell stack is made up of several individual fuel cells.

Freudenberg already has more than 20 years of unique expertise in the development and production of gas diffusion layers for fuel cell applications in the mobility sector and for porous transport layers used in electrolyzers. Freudenberg is currently expanding its production capacity at its Weinheim headquarters by installing additional lines. Further investments are on the verge of implementation.

• Collaboration between Indorama Ventures and Toyobo to meet growing global demand for airbags
• Newly completed plant in Thailand will supply high-performance nylon yarn to customers in the automotive safety sector

Indorama Ventures Public Company Limited (IVL) celebrated the completion of a plant to manufacture high-performance nylon yarn for automobile airbags. The new plant in Rayong, Thailand, was constructed by Toyobo Indorama Advanced Fibers Co., Ltd. (TIAF), a joint venture that Indorama Ventures established with Toyobo Co., Ltd in November 2020.

The plant, which has been built on the site of Indorama Polyester Industries PCL (IPI) in Rayong Province, will deliver 11,000 tons of high-performance yarn per year to meet global demand for airbags that is expected to grow by 3 percent to 4 percent annually as automakers equip vehicles with more airbags and emerging economies require cars to adopt more safety features. Test production is scheduled to start in October 2022 with the goal of starting commercial production in the middle of 2023.

In 2014, Indorama Ventures and Toyobo jointly acquired Germany’s PHP Fibers GmbH, a leading airbag yarn maker. Since then, both companies have strengthened their relationship with a focus to expand in the automotive safety sector. Mr Christopher Kenneally, based in Bangkok, leads IVL’s Fibers segment, which produces fibers and yarns across its Hygiene, Mobility and Lifestyle verticals. Mr Ashok Arora, with over 30 years of experience in fibers and polymer operations, will helm TIAF as CEO while maintaining his role as CTO with IVL Fibers.

RHEON LABS, a fast-growing materials technology company based in Battersea, London, has completed an extensive 6 month trial with FET, a world leader in laboratory and pilot meltspinning equipment. Backed by a £173,000 grant from Innovate UK for feasibility studies, RHEON LABS has further developed its RHEON™ technology, a reactive polymer that dynamically stiffens when subjected to force. The technology can control energy of any amplitude or frequency, from small vibrations to forces at ballistic-speeds and therefore has a wide range of applications.
 
This Innovate UK Smart Grant-backed project aims to develop a hyper viscoelastic fibre from RHEON™ which displays high strain-rate sensitive properties. Creating a fibre with unique strain-rate sensitive properties will be a world first. It will enable the creation of a 'breakthrough-generation' of stretch textiles that can actively absorb, dampen and control energy during movement, rather than simply acting as a spring.

For close-fitting activewear and sports bras, the ability to actively control muscle mass or soft tissue movement during exercise will be a game-changing advancement. It will allow brands to engineer garments that relax during everyday use but actively stiffen during exercise for improved support and performance.
The Innovate UK grant was awarded under the category of Hyper-Viscoelastic Fibre Extrusion for Textile Manufacture. Fibre Extrusion Technology Limited (FET) enabled the customer trials at its bespoke Fibre Development Centre in Leeds, England using its in-house FET-103 Monofilament meltspinning facilities, in harness with RHEON and FET technical operatives. The next phase will be to upscale the trials of preferred materials on RHEON’s own new FET-103 meltspinning line, with FET’s continued support and expertise on hand.
 
Creating a fibre with unique strain-rate sensitive characteristics could be as radical a change in the market as the initial introduction of stretch fibre with the launch of Lycra™. The textiles would have a multitude of beneficial properties and would provide significantly less compression in the garment than conventional materials, substantially improving user comfort, support and performance.

• 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.

Freudenberg Performance Materials – the Freudenberg Group’s nonwovens specialist – was hosting a meeting of the German National Hydrogen Council at the Freudenberg headquarters in Weinheim, Germany, on September 16. As a leading global supplier of technical textiles, Freudenberg Performance Materials provides fuel cell components for mobility applications and for electrolyzers used to produce CO₂-free hydrogen.

The German National Hydrogen Council was appointed by the German government and acts as an independent, non-partisan advisory board. The council board currently consists of 25 high-ranking experts in the fields of economy, science and civil society. The objective is to assist and advise the State Secretaries’ Committee on Hydrogen in the further development and implementation of Germany’s National Hydrogen Strategy. Council meetings are hosted by one of the board members to enable the council to deepen its knowledge of the relevant technologies, value chain roles and challenges. Dr. Silke Wagener is a member of the council board, and represents the Freudenberg technology group, giving input on suppliers’ know-how as well as contributing her decades-long expertise in technological solutions for the hydrogen industry.

During a tour of the factory organized for the council board members, Freudenberg Performance Materials explained the development and production of performance-critical gas diffusion layers manufactured from carbon fiber-based nonwovens for fuel cells and porous transport layers for electrolyzers. The tour highlighted the potential for improvements from a supplier’s perspective, such as the need for very timely exchange and collaboration along the value chain. Functioning, unbroken and scalable value chains, in parallel with the development and scaling of hydrogen infrastructure, are key prerequisites for the hydrogen industry to fulfill its vital role in the transformation to climate neutrality.

Gas diffusion layers are one of the main components at the heart of the fuel cell. Their function is to transport gases and liquids in the cells. They have a significant impact on system performance and costs, and are indispensable for the functioning of fuel cells. The same applies for porous transport layers that are the key component of electrolyzers for the CO₂-free production of what is called green hydrogen.

Fuel cells in combination with green hydrogen are an important technology for CO₂-free mobility, in particular with reference to buses, heavy-duty trucks and trains. Other uses include stationary applications such as stationary power generation or heat generation in buildings or industry.
Apart from mobility, green hydrogen also plays a key role in climate-neutral energy supplies in the industrial sector, particularly in the chemical and steel industries.
