In a total of four micro-factories at the up-coming Texprocess, trade visitors will be able to get an idea of how integrated textile processing works and wher micro-factories are already being used, according to a press release.
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 in hall 4.1. The ‘Digital Textile Micro-Factory’ will showcase three 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.
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 individualised 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 visualised 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.
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.
Industry 4.0 live: the focus of the third production line of the ‘Digital Textile Micro-Factory’ 2019 is on the automated processing of technical textiles, personalised 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.
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.
Six companies have grouped together under the ‘World of Digital Fashion’ umbrella. They work in areas of visualisation, 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 customisation of apparel and fashion items.
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. (GK)
