Innovative technical textiles like precursor yarns for carbon fibres made from renewable raw materials are produced and improved with DIENES spinning systems. Growing demands on the varying quality of recycled feedstock, the implementation of biobased materials and ensuring fibre performance require a continuous development and optimisation of both technology and production parameters. A reliable development of textile and technical filament yarns demands an efficient, systematic and, in part, self-optimising experimental working system which must be intelligent and flexible. At Techtextil, DIENES will present its approach towards digitalisation which is called MultiMode®. In a MultiMode® plant, each process step is represented by a module which can be individually adapted to customer-specific requirements and has its own decentralised control. Thus, DIENES production lines consist of several intelligent modular units which can be easily exchanged and rearranged at any time with a reduced programming effort. Moreover, all production parameters can be permanently visualised and recorded, enabling a complete traceability of the process.
