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.
Asahi Kasei Europe: new location and R&D center in Düsseldorf
In March 2021, the Asahi Kasei Europe R&D Center of the producer of fibers, chemicals and electronics, Asahi Kasei Corp., Osaka/Japan, relocated from Dormagen to the new location in Düsseldorf/Germany. By uniting European sales, marketing and R&D activities, the compnay further enhances its business approach towards the European automotive industry.
In the new showroom the company displays its materials and solutions for the future automotive, ranging from sustainable microfiber materials for interior seat and headliner coverings to innovative foam products and separators for battery applications. The adjacent hall building is home to the Asahi Kasei Europe R&D Center, with laboratory space for various materials, such as engineering plastics, synthetic rubber, as well as for battery and coating materials.
Already in November 2020, Asahi Kasei Europe GmbH and its sister company Asahi Kasei Microdevices Europe GmbH started office operation at the new “C-View Offices” at Düsseldorf Harbour.
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.
We are SpinDye: sustainable dyeing technology for H&M’s collections
From April 15, 2021, Hennes & Mauritz AB (H&M), Stockholm/Sweden, will launch the latest Innovation Stories collection, Color Story from H&M. For these textiles a very resource-efficient dyeing process of spin-dyeing company We are SpinDye, Stockholm/Sweden, is used. By using this technology when dyeing textiles, water consumption is reduced by 75 % and chemical consumption by as much as 90 % compared with traditional water dyeing of fabric.
Reports show that dyeing alone accounts for almost 24 % of the resources consumed during a garment's entire lifetime. From raw material, through production and use to recycling or in the worst case the landfill. In just one year, the clothing industry uses 9 billion m³ of water and 168 million tons of process chemicals to dye fabrics. By using the We are SpinDye technology the wet dyeing can be avoided completely by adding color pigments to the fiber in the same moment as the fiber is made. In this way, water, chemicals and CO2 can be reduced to a minimum.
The fact that more companies in the fashion industry must pay attention to the negative environmental effects that occur when dyeing textiles has been big driving force for alternative dyeing technologies.
FET: new laboratory spinning system for driving technological innovations
In Indonesia at the Center for Textile, Bandung, a new FET-100 Series Laboratory Melt Spinning System for continuous filament yarn applications has been installed by the supplier of extrusion technology Fibre Extrusion Technology Ltd. (FET), Leeds/UK.
The Center for Textile, Balai Besar Tekstils of Bandung, has the task of carrying out research, development, cooperation, testing, certification and competency development of the textile sector, under the control of the Ministry of Industry (Kementerian Perindustrian). The Ministry has a stated objective that Indonesia becomes a “Resilient Industrial Country” - strong, competitive and based on innovation and technology.
The FET-100 system will play a vital role in driving technological innovation in the Indonesian textile industry. The nation’s fiber manufacturers now have access to advanced melt spinning facilities for developing and testing their own novel fibers for global applications. This laboratory melt spinning system is multi-polymer capable and can produce both mono and bi-component formats.
