From the Sector

Freudenberg Performance Materials (Freudenberg) offers a range of efficient interlinings, tapes and thermal insulation materials for workwear and protective clothing. The materials not only withstand diverse kinds of strain they are exposed to in everyday work and washing procedures but also offer great comfort.

Innovative materials and manufacturing technology
The nonwoven and woven interlinings and tapes stand out due to a number of features, such as increased stability, elasticity, abrasion resistance and wind-blocking properties. Thanks to the sophisticated adhesive technology used by the manufacturer of technical textiles, some products are especially resistant and durable.

Highly flexible and resilient interlinings as well as Freudenberg comfortemp® thermal insulation materials are used for protective clothing, and they do not only protect the wearer from danger but also ensure the wearer’s comfort in any kind of weather. Furthermore, hem and edge stabilisation tapes ensure optimal fit and reflective tapes provide additional safety.  

Active contribution to sustainability
Many products of the Freudenberg Workwear Range consist of a high percentage of recycled polyester coming from post-consumer PET bottles.

ISKO and textile research and development company HKRITA are proud to announce a licensing agreement for HKRITA’s award-winning, revolutionary Green Machine – a one-of-a-kind technology that fully separates and recycles cotton and polyester blends at scale.

The technology is still in the pilot stage, but is an additional step in ISKO’s drive to improve and commercialize recycling technologies which will eventually enable the company to offer a 100% post-consumer recycling solution to all of its customers. In addition, ISKO and HKRITA will work together to develop related technology, further strengthening the company’s position in sustainability.

The Green Machine uses an innovative and ultra-efficient hydrothermal treatment method that decomposes cotton into cellulose powders and enables the separation of polyester fibres from blended fabrics. The process is a closed loop and uses only water, heat and less than 5% biodegradable green chemicals. Crucially, this method does not damage the polyester fibres and therefore maintains their quality; the cellulose powders, which are clean and toxic-free, can be used in a variety of ways.

The investment in this new technology is the latest in ISKO’s ongoing drive for advancements in sustainability. As part of the company’s R-TWO™ programme, it is also working to develop fabrics with a guaranteed minimum 50%+ GRS (Global Recycle Standard) recycled content blend. This will significantly reduce the carbon and water footprint of a fabric, as well as make it easy for consumers to trace a garment’s sustainable journey step-by-step from the beginning of the supply chain through to the end product they purchase.

• Xinfengming Group invests in innovative staple fiber technology from Oerlikon Neumag

Neumuenster/Shanghai – In the context of the ITMA ASIA + CITME currently taking place in Shanghai, Oerlikon has now announced that it has concluded the largest staple fiber plant order in the history of Oerlikon Neumag with the major Chinese group Xinfengming in the run-up to the trade fair. This involves eight complete staple fiber lines with a total of 320 spinning positions for the production of synthetic staple fibers. Oerlikon will not only supply the technology, but will also take over the engineering of the lines. Delivery is scheduled for 2022.

With a total capacity of 1,800 t/d, the project is Oerlikon Neumag's largest staple fiber plant order to date. The eight two-step lines will produce cotton-type staple fibers in a titer range of 1.0 - 1.4 denier. With this investment, the Xinfengming Group is expanding its product portfolio. As one of the world's leading FDY and POY polyester filament yarn producers, the Chinese company has relied on Oerlikon Barmag technologies for decades and now also on those of Oerlikon Neumag.

Sappi offers Transjet Tacky Industrial, a coated dye sublimation paper for digital transfer printing, specially developed for high-speed inkjet printing on highly elastic textiles. Also new is the uncoated dye sublimation paper Basejet, which has been developed for light designs for high-speed digital printing of fashion and home textiles.

• Transjet Tacky Industrial: Immediate tack effect, high ink transfer, fast ink drying; no ghosting on elastic textiles thanks to reversible tack
• Basejet: Consistent print quality for light designs, fast ink-drying, very fast transfer process

Transjet Tacky Industrial enables highly elastic fabrics to be printed on industrial high-speed machines that work with a higher glycol content, such as printheads from Kyocera. The paper is first printed with the desired image or pattern which is then transferred to the elastic polyester fabric by means of heat and pressure.

Sublimation paper for the textile industry
The new dye sublimation paper offers many benefits for the textile industry, which frequently has to adapt to changing trends. As it is suitable for use on high-speed digital printers, significantly more designs can be printed in the same time than was previously possible on plotters. Thanks to a special heat-reactive coating, the paper adheres to highly stretchable content, while the reversible tack prevents ghosting and textile shrinkage. Transjet Tacky
Industrial has a high ink load capacity so the print can be better accentuated due to strong colour saturation. The design remains clearly visible when the fabric is stretched to its maximum, which is often the case with sportswear in particular.

Basejet specially for light designs
Sappi has also added the Basejet uncoated dye sublimation paper to its portfolio, an additional solution for the digital printing of fashion and home textiles in consistent print quality. The uncoated dye sublimation paper is intended in particular for light designs and cost-driven production processes.

Alchemie Technology, a leader in waterless, digital on-demand, smart dyeing technology, has today announced its partnership with HeiQ, a leader in textile innovation, as it prepares the production rollout of its NOVARATM digital multifunction finishing solution to the global textile market in Q3 this year.

NOVARA can apply single-sided, or simultaneous two-sided, coating of multiple finishes to specific areas of textile. For example, combining anti-odour and water repellence in one material.

“For example, using NOVARA for single-sided finishing of HeiQ Viroblock required 52% less chemistry, 66% water reduction and 50% less energy, whilst achieving a 99.7% reduction in antimicrobial activity after 15 washes at 400celsius. With the huge demand for high-performance antibacterial, antiviral finishing for face masks, medical apparel, gym wear, home furnishing, mattresses, and textiles for high-risk, high traffic areas such as train, plane seats, and more, our combined technology is critical for increasing protection and reducing environmental impact of these products” says Dr Simon Kew, Managing Director, Alchemie Technology.

NOVARA also enables unique lifestyle product innovations at lower production cost for fashion, sportswear, technical clothing, and upholstery such as combining sustainable odour control, skin care additives, and fragrance finishing, without impacting breathability, hand feel or wicking. It is suitable for finishing all fabric types, from 50 - 1000 gsm, including polyester, cotton, nylon and polycotton.
