From the Sector

December 29, Renewcell dispatched the first shipment of Circulose® dissolving pulp produced at its Renewcell 1 plant in Sundsvall to a customer. This sale is the latest step in the ramp-up of Renewcell 1 to its initial capacity of 60,000 tonnes per year.

Founded by innovators from Stockholm’s KTH Royal Institute of Technology in 2012, Re:NewCell AB (publ) (‘Renewcell’) is a multi-award-winning sustaintech company based in Sweden. The company’s vision is to make fashion circular. Through its patented process, Renewcell is able to recycle cellulosic textile waste, such as worn-out cotton clothes and production scraps, transforming it into a pristine new material called Circulose®.

Valérius 360 wanted to make a sustainable, circular approach possible in the fashion industry. Working together with Trützschler, a collaborative project has now achieved high-quality recycled yarn – opening up massive potential to drive measurable progress toward a circular and sustainable textile industry.

Testing at the Trützschler Technical Center
The team from Valérius 360 wanted to find ways of improving the processes for yarns made from 50 % recycled and 50 % virgin cotton (Ne30). In particular, it was seeking ways to reduce thick and thin spots, which disturb the appearance of the textile surface.

At the Trützschler Technical Center in Mönchengladbach, they conducted special trials that showed that using a direct spinning process for this application delivers much better results than a process with a draw frame passage for rotor yarns.

In direct spinning, the sliver from the card is directly drawn in the draw frame which is integrated in the can stock. This involves one less process step than using an autoleveller draw frame, while also saving space and giving staff more time for other operations.

On-site support from Trützschler Customer Service
The team from Valérius 360 also received in-house training from the Trützschler Customer Service department. Together, they analyzed and significantly improved the process at the Valérius 360 production site. This helped to bring yarns made from recycled raw materials up to the required level of the 50% Usterstatistics. This is the reference level for yarns made from virgin raw materials. Accordingly, 50 % of all yarn producers with raw cotton for rotor yarns and comparable yarn counts produce a poorer quality.

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.

• Auraloop is a brand-new range of cushioning solutions made from an innovative structure of Polyester-based fibers, 100% recyclable, aimed at the mobility markets
• One of the objectives of Auraloop is a twofold reduction in the carbon footprint of car seat pads, currently made from polyurethane foam
• Auraloop offers an increased level of performance in terms of thermal comfort and durability

R&D teams within the Faurecia seating activity have recently penned an exclusive development agreement with Indorama Ventures. This partnership between Indorama Ventures and Faurecia, a company of FORVIA Group which is one of the largest automotive industry suppliers, has the aim of developing Auraloop, a new range of cushioning solutions for the mobility markets and intended to replace polyurethane foam currently used in car seats.

“By setting out these initial milestones in our close-knit collaboration with Faurecia, this partnership is an integral part of Indorama Ventures’ commitment to expand its existing Polyester (PET)-based portfolio and related activities into wider areas. By bringing together two leading players in the automotive industry, we aim to open up further growth opportunities for both partners”, stated Arnaud Closson, Chief Executive Officer at Indorama Ventures’ Mobility Group / Fibers Segment.

“Auraloop will replace those materials currently used in car seating with innovative and sustainable materials, based on polyester fibers that offer a total recyclability of 100%. This new material will allow for a twofold reduction in the carbon footprint of car seat pad solutions compared to current materials”, explains Nicolas Michot, Director of Technology at Faurecia Seating. Development of this product, which paves the way towards wider commercial release in two or three years, falls within the FORVIA Group strategy of going carbon neutral by 2045. For this, the group is seeking to root its commercial offer fully in the circular economy, with the development and production of sustainable cutting-edge materials under the banner of MATERI’ACT.

Auraloop offers a range of new perspectives in terms of seating comfort thanks to a more open fiber structure and permeability for air than current seating pad solutions, the breathability of seating is improved, enabling a better passive thermal regulation of occupants. The durability of seating is also increased by limited subsidence of the seat over its lifetime. The market for comfort aboard vehicles is constantly growing. The development of Auraloop falls within this dynamic, with a product offering significantly improved performances in terms of static, dynamic and welcoming comfort.
