During the international trade fair for technical textiles and nonwovens Techtextil and the Texprocess, trade fair for processing textile and flexible materials on Mai 14-17, 2019 in Frankfurt/Germany the focus is also on individualization, automatization and digitalization.

Techtextil and the parallel Texprocess will be sharing an exhibition hall for the first time. Suppliers of functional apparel textiles and the 'Digital Textile Micro Factory' mark the transition to Texprocess, which will be showcasing different production lines for clothing, shoes, and the processing of technical textiles.

Digital Textile Micro-Factory: on-demand and virtual reality

Following the success of the last event, Texprocess, in collaboration with the German Institutes of Textile and Fibre Research in Denkendorf (Institute für Textil- und Faserforschung Denkendorf – DITF) and partners from industry, will once again be presenting a ‘Digital Textile Micro-Factory’ display - and thus fully networked production chains – live.
The ‘Digital Textile Micro-Factory’ will showcase 3 production lines – one for apparel manufacture, one for 3D-knitted shoes and one for processing technical textiles, largely for the motor-vehicle and furniture industries.

‘Fashion Line’ integrates virtual prototypes and customer interaction

The fashion industry plays a central role in the ‘Digital Textile Micro-Factory’. The customer’s digital doppelganger is becoming more and more important in development departments in the apparel industry as the starting point for individualized and perfectly fitting clothes and for links with finishing departments. In the context of the micro-factory’s production line, it is the key feature.
The production line demonstrates the various stages involved, including CAD/Design, printing, cutting out, assembly, finishing and labelling. New approaches also combine 3D simulations of clothing with direct data transfer in virtual reality (VR) and augmented reality (AR). Instead of presenting the customer with physical examples of the clothing to be produced, the examples are visualized as virtual objects. And during the production process, the customer has the opportunity for direct input into the design of the product in question. This direct interaction between the 3D simulation of an item, the representation in VR/AR displayed on the customer’s own hardware and the direct impact on the production process has never been shown before in this way. Partners of the ‘Fashion Line’ are: Assyst (CAD/design), Mitwill (materials), Caddon, ErgoSoft, Mimaki and Multiplot (printing), Zünd (cutting), Juki and Stoll (assembling), Veit (finishing) and Vuframe (AR/VR).

3D knitting on the way to Industry 4.0

From 3D image to finished prototype in 18 minutes: the future is here in the world of knitting too! The ‘Digital Textile Micro-Factory’ at Texprocess and Techtextil shows a workflow which enables 3D-knitted uppers for shoes to be produced directly from the customer’s own particular foot measurements.
The ‘3D-knitting line’ of the micro-factory demonstrates the process from the 3D model to the creation of a geometrically accurate knitting pattern by the software, based on the 3D data set, and the development of a specification of the final knitting data, through to the manufacture of a 3D-knitted prototype. Knitting is the additive manufacturing process for textiles. The ‘3D-knitting line’ is partnered by Stoll.

Processing technical textiles in the micro-factory
Industry 4.0 live: the focus of the 3rd production line of the ‘Digital Textile Micro-Factory’ 2019 is on the automated processing of technical textiles, personalized for the individual customer, taking us right through to the finished product. Trade visitors will see here on-demand inkjet printing and networked machines with integrated sensors, which are linked through a bus system – a future-oriented topic for integrated manufacturing. A robot arm with a special claw for use with textiles sorts the cut items as they emerge from the cutter in a free-moving open shuttle. The items to be sewn are conveyed automatically to the sewing stations. Tracing and tracking procedures show the progress of each order through the individual stages of the manufacturing process using an auto ID. In addition, the display will also show how creative ideas from the Cloud can be incorporated in the manufacture of technical products - technology meets creativity. Partners of the production line are: Mitwill (design), ErgoSoft (RIP), Caddon (color management), HP (large-format inkjet printing), Zünd (cutting), Dürkopp Adler (networking, integration of an open shuttle, sewing), Veit (finishing), Next Robotics (material handling).

Smart Textiles Micro-Factory: industrial-type production of smart textiles
In their ‘Smart Textiles Micro-Factory’, located in the walkway between Halls 4.1 and 5.1, the Institute for Textile Technology (ITA) at the RWTH Aachen University, together with partners from industry and research, will be producing a ‘smart’ pillow which, with the help of integrated LEDs, provides new ways of interaction. With this demonstration, the partners in the project will present an exemplary, industrial-style manufacturing process for a smart textile from design to finished product. The prototype of the pillow was displayed in advance at Heimtextil 2019.
The following are all involved in the ‘Smart Textiles Micro-Factory’: the Institute for Textile Technology (ITA) of the RWTH Aachen University (project coordination), Gerber Technology GmbH (cutting), the Korea Institute for Industrial Technology Kitech (electronics), VetronTypical Europe GmbH (sewing), Wear it GmbH (product design and concept) and ZSK Stickmaschinen GmbH (embroidery).

World of Digital Fashion: customization of apparel
6 companies have grouped together under the ‘World of Digital Fashion’ umbrella. They work in areas of visualization, CAD-cutting systems, automated body measurement, cutting out and process automation. Together, they will be showcasing, in Hall 4.0, ways of integrating and combining their products in a variety of workflows within the value creation chain and will enable visitors to experience what the digital process chain is like in practice. The focus will fall particularly on the customization of apparel and fashion items. Partners of the ‘World of Digital Fashion’ are: Browzwear Solutions and Tronog (visualisation), Software Dr. K. Friedrich (CAD), Fision (automated body measurement), Bullmer (cutting), as well as Gertsch Consulting and Mode Vision (process automation).

Micro-factory presented by Efka and Gemini: easy to implement
Manufacturers of drive mechanisms for industrial sewing machines Efka will, in collaboration with CAD suppliers Gemini, be showcasing the production of a knitted garment that can be individually designed. The core element of their micro-factory, which closely reflects industrial practice, is the link to the sewing stage of production, something which is already available today as an economic, partially automated solution. The display presents a solution that can be easily implemented and adopted by most companies, using already available resources.
