• 76 KL/Day water saving by optimizing pH analysis process in dye vessels
• A step closer to achieving the ‘Huntsman Horizon 2025’ goal
• Potential savings of over Rs 10 crore or USD146,000 annually from the project

Huntsman Textile Effects, the global leader in innovative and environmentally sustainable dyes, chemicals, and digital inks, has successfully implemented a water conservation process to improve water efficiency and reduce net water usage at its Baroda facility, which is located in the western region of India. The initiative undertaken at the plant aims to save around 76 kilo liters of Reverse Osmosis water per day by modifying the phase sequence in the pH measurement program.

Water is used extensively throughout textile processing operations. The amount of water used varies widely in the industry, depending on specific processes operated at the plant, equipment used, and policies concerning water use. This conservation project at the Baroda Plant will have a potential savings of Rs 10 crore or USD146,000 a year for the organization.

Speaking on the development, Mark Devaney, Vice President Manufacturing and Operations Excellence, Huntsman Textile Effects said, “At Huntsman, we recognize the important role we play in creating a more sustainable future and are committed to the well-being of the communities where we operate, and the protection of the environment. We are continually looking for ways to improve the environmental footprint of our manufacturing sites and have been implementing numerous projects in recent years to reduce our water usage.”

“The team has done a detailed assessment of the pH analysis process in dye vessels, mapping the existing water usage and potential conservation method. After a brief study and several brainstorming sessions, we were able to adjust the phase sequence, resulting in conservation of Reverse Osmosis water by almost 76 kilo liters of water per day.” said Kavishwar Kalambe, Site Director, Huntsman Textile Effects. “This project directly contributes to Huntsman’s Horizon 2025 goals to reduce net water usage at facilities in water-stressed regions,” he added.

• Hexcel HexPly® XF Selected for High-Quality, Paint-Ready Parts for Sunseeker 90 Ocean Luxury Yacht
• Hexcel’s innovative surface technology yields parts with paint-ready surfaces for builder of luxury yachts

Yacht builder Sunseeker has chosen Hexcel’s HexPly® XF surface technology to produce prepreg parts with high-quality, paint-ready surfaces quickly and efficiently for its 90 Ocean luxury yacht, one of its newest models.

The lightweight composite hardtop for the Sunseeker 90 Ocean yacht is manufactured from a combination of HexPly® XF and Hexcel's HexPly® SuperFIT® semi-preg. The hardtop is lighter in weight than versions made using resin-infusion processes, and it de-molds with a pinhole-free surface that needs minimal preparation to be ready for paint. Sunseeker has recorded an overall reduction in process time of around 30%, saving three days of manufacturing time per hardtop.

The hardtop provides shade and protection for the yacht’s uppermost deck space. Its reduced weight helps to ensure the stability of the vessel, and the paint-ready finish with HexPly XF provides Sunseeker with more options for customizing its color to the individual needs of its clients.
 
HexPly XF is a lightweight, non-woven semi-preg that eliminates the need to use a traditional in-mold gel coat. The innovative surface technology significantly reduces the costly and time-consuming refinishing work typically required to impart a paint-ready finish to prepreg or semi-preg parts, and yields lightweight, consistent components in short cycle times.

Working with Sunseeker, Hexcel developed a material format, a laminate ply sequence, and a production process that satisfied the structural requirements for the hardtop and enabled the yacht builder’s production team to lay up and cure the part in a single shot – slashing cycle times.

Hexcel supplies Sunseeker with a HexPly XF product that comprises both the surface layer and the first structural reinforcement ply, eliminating the need for a cosmetic barrier coat. Neither the HexPly XF surface layer nor the following layers of HexPly SuperFIT require time-consuming debulking steps – significantly reducing lay-up time – and both are based on Hexcel's rapid-curing M79 epoxy resin system. Adhesive resin films are not needed to bond the hardtop’s foam core, as the resin content of the SuperFIT plies has been adjusted to further reduce overall process time.

Once de-molded, the cured hardtops are inspected before they are passed to Sunseeker’s finishing and painting technicians for final preparation and painting. The HexPly XF resin surface allows the yacht builder’s quality technicians to inspect the laminate below quickly and easily, ensuring the quality and consistency of the structural reinforcement plies.

“Composite materials that improve our production processes, as well as great technical support, are what makes working with Hexcel such a success story," said Stuart Vaughan-Jones, Composite Development Manager, Sunseeker. "With the switch from gel coat and resin infusion to HexPly XF and SuperFIT in the new hardtops, we are now building lighter, more consistent parts, more quickly than before, with a higher quality surface finish. XF really has ticked all the boxes.”  

Garth Thomas, Account Manager – Marine, Hexcel, said: "With the HexPly XF surface technology now well established, XF will soon be used in other large moldings where minimizing weight is critical, as well as additional hardtops across the Sunseeker model range."

Promising conditions in the technical textiles and nonwovens market are expected to provide ample opportunities for suppliers at this year’s Cinte Techtextil China. The fair, which last year saw 366 exhibitors and 14,868 visits, will take place from 6 – 8 September 2022 at the Shanghai New International Expo Centre. Flexible exhibiting options will once again be available for overseas companies.

Ms Wendy Wen, Senior General Manager of Messe Frankfurt (HK) Ltd, explained the positive conditions that exhibitors should expect at the fair thusly: “The pandemic has led to a surge in Chinese exports of both technical textiles and nonwovens, the latter in particular. The country remains the largest supplier of nonwovens, comprising one-third of the global total, yet still requires the advanced offerings of overseas machinery suppliers, as well as supplies of raw materials, to support its export production.”

Ms Wen continued: “Domestically, China is seeing increasing consumption of functional apparel, sportswear and personal protection items. Heightened health and sanitary regulations and new hygiene habits will also continue to drive demand, especially for nonwovens, well into the future. There has also been a post-pandemic boost in demand for filter, greenhouse covering and high-density fabrics amongst others. All of this adds up to a wealth of opportunities for overseas companies to take advantage of, as was experienced in the 2021 edition of the fair.”

Exhibitor and visitor experiences in 2021
“Our organisation promotes US cotton and we hope to use this platform to meet more companies and brands in the nonwovens industry who are interested in US cotton, and to meet up with old friends to discuss the current situation and industry trends.

Freudenberg Performance Materials announces a general upward adjustment of their prices for nonwoven performance materials for flooring and filtration applications in EMEA. This revision, effective January 1, 2022, has become necessary because of sustained and unprecedented surge in cost for raw materials, packaging, freight, consumables and energy combined with disruptions in their inbound supply chain.

Prices across all categories have by far outpaced their expectations and are forecasted to remain on high levels throughout 2022. This historic price trend has placed significant pressure on Freudenberg Performance Materials, and they understand in a similar way on their customers.

At this stage their business can no longer absorb the effects of such high price levels. Freudenberg Performance Materials will therefore adjust our prices for all their Colback® and Lutradur branded nonwoven products for flooring and filtration application by double-digit increases depending on product types.

Freudenberg Performance Materials will continue to work on improving productivity to offset inflationary pressure to keep attractive price levels and to avoid further price adjustments. They will continue to monitor the market development and in case of sustained and unexpected downward trends they will adjust our prices accordingly.

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

Submissions for the next Innovation Award can be made from the end of January 2022.

The acoustic performance of components for the vehicle interior such as inner dashes or carpets depends on the noise-reducing quality as well as the geometrical adaptability and fill power of their material. With Flexi-Loft, Autoneum offers a new felt-based technology that thanks to a unique blend of recycled cotton and functional fibers reduces product weight and allows for accurate adaptation even to complex shapes. The textile material therefore provides a versatile and more sustainable alternative to foam.

In order to achieve high acoustic performance at minimum weight and maximum sustainability, Autoneum is continuously advancing its textile product portfolio. When it comes to components for the vehicle interior, for example, standard thermoplastic felts excel through their acoustic absorption, robustness and environmental friendliness. However, since felt-based materials are generally less voluminous and moldable as foam components, they require more weight to thoroughly fill the areas of varying thickness between the surface of the component and the vehicle’s body-in-white. In contrast, Autoneum’s Flexi-Loft technology is significantly lighter, more flexible and more adaptable than standard felts. In addition, the fiber-based material is versatile and clearly outperforms current foam products in terms of sustainability.

Thanks to its blend of recycled cotton and polyester fibers, Flexi-Loft substantially reduces component weight while improving geometrical adaptability and acoustic performance, especially in areas of low thickness. Thanks to the specific properties of the fibers, Flexi-Loft enables a precise adaptation to a wide variety of vehicle bodies, thereby improving the noise-insulating qualities of the respective product. Even at low weight, Flexi-Loft covers a wide range of material thicknesses, thus proving to be an ideal decoupling material for interior components with complex shapes such as inner dashes and automotive carpets. As a lightweight, flexible and sustainable alternative to both standard felts and foam, Flexi-Loft distinguishes itself by its versatile application in combination with existing Autoneum technologies such as Hybrid-Acoustics and Prime-Light. Moreover, the material helps to reduce odor and dust inside the vehicle.

Flexi-Loft consists of at least 50% recycled cotton fibers, and cut-offs generated during the manufacturing process are reclaimed, processed and then reused in the production of new felt blanks.

Autoneum is already using Flexi-Loft worldwide as an insulator for various carpets, inner dashes and other acoustic components based on its Prime-Light technology. The application of the material as an effective decoupler in inner dashes made of Hybrid-Acoustics will be launched on the European market in 2023.
