ITA/AMAC: cooperation for business development in composites
To strengthen and develop their business activities in composites, the Institute for Textile Technology at RWTH Aachen University (ITA), Aachen/Germany, and their ITA GmbH, has entered into a cooperation with industrial and business consulting company AMAC GmbH, Aachen.
The ITA develops complete solutions from the manufacturing of the fiber itself over the processing of textile intermediates with thermoplastic and thermoset resins, textile-based part manufacturing, capabilities such as braiding, pultrusion and in-situ impregnation of textile preforms. Top 3 focused industries are transportation and particularly the e-mobility sector, building and construction as well as the wind energy sector. Additionally, ITA GmbH is the partner of the industry in R&D, focusing on 8 business segments, providing technology and knowledge transfer, as well as offering comprehensive solutions along the entire textile value chain.
The background of the strategic cooperation with focus on composites is the long-term experience and know-how with all aspects of continuous fibers, nonwovens and web-based reinforcements which allows the ITA to deliver to the composite manufacturers a complete technology and service offer around the development of technical textiles.
Shima Seiki: digitally transformation of the fashion supply chain
On April 27-29, 2021, at the 36th Spinexpo trade fair in Shanghai/China, the manufacturer of flat knitting machines Shima Seiki Mfg., Ltd., Wakayama/Japan, will introduce its new ApexFiz subscription-based design software. This is the latest addition to Shima Seiki’s proven SDS-one Apex series design system lineup.
Whereas previous Apex-series design systems were offered as an all-in-one proprietary hardware/software package, for the first time the company has released its new ApexFiz as subscription-based design software that can be installed on customers’ individual computers. Maintaining proven functions that have made the Apex series so popular with fashion designers, with ApexFiz those strengths are now enhanced with the added versatility to adapt to different work styles and business environments of the “new normal” including teleworking and telecommuting. ApexFiz software supports the creative side of fashion from planning and design to colorway evaluation, realistic fabric simulation and 3D virtual sampling. Otherwise known as “digital twins”, virtual samples are a digitized version of sample making that are accurate enough to be used effectively as prototypes, replacing physical sampling and consequently reducing time, cost and material that otherwise go to waste. This technology thereby helps to realize sustainability and digitally transform the fashion supply chain.
Teijin: nanofiber made from rPET
The fiber-product converting company Teijin Frontier Co., Ltd., Tokyo/Japan, claims to have developed the first nanofiber to be made from recycled polyester raw materials. With this new technology a new version of its Nanofront ultra-fine polyester can be produced.
Teijin Frontier expects filaments and textiles made with this new version of Nanofront made from recycled polyester materials to replace conventional Nanofront made from petroleum-derived raw materials in a wide range of fields, including sportswear, functional clothing, industrial uniforms and more. These rPET nanofibers offers the same functions as conventional Nanofront.
In recent years, the demand for Nanofront has expanded in a wide range of fields due to growing needs for materials offering high functionality, such as absorbency and grip, and very good comfort including soft texture and low skin irritation. Meanwhile, the demand for recycling raw materials is rapidly increasing, but it has been difficult to mass produce ultra-fine fibers made from recycled polyester due to needs for high-level polymer control and spinning.
Teijin Frontier has now developed new polymer-control and spinning techniques for Nanofront made from recycled polyester materials. The key was the company’s proprietary “sea-island” composite-fiber processing technology, which distributes 2 types of polymers into the fiber’s "sea" and "island" parts, then dissolves and removes the "sea" part using an alkaline, etc. treatment, and finally extracts only the "island" part as raw yarn.
