The joint project ‘Energy and Sustainability in the Textile Industry: Energy Efficiency and Renewable Energies in Partnership for Climate Protection’, funded by the Federal Ministry of Education and Research (BMBF) from 2021 to 2025, aims, among other things, to support the Indonesian textile industry on its path to a sustainable future. As part of this project, ifeu is responsible for the ecological assessment of current processes in the Indonesian textile industry and measures for greater sustainability. This includes, among other things, the optimisation of processes, the substitution of technologies and the comparison of technologies and textile products. The questions included in the ecological assessment were defined by the project partners.

One of these questions was suggested by Brückner Trockentechnik GmbH & Co. KG and deals with so-called stretching, drying and fixing machines, hereinafter referred to as stretching machines, a technology for drying, finishing and thermofixing textile fabrics in the textile industry. There are various technical designs for this, ranging from relatively simple, commercially available machines to innovative, high-performance, high-quality machines.

Since drying and thermofixing, as sub-processes of industrial textile finishing, are considered particularly energy-intensive and therefore harmful to the environment, and since the different technical designs of stretching machines can have significantly different energy requirements, the focus of the research can be limited to the effects on climate change.

The main interest lies in identifying the differences in the carbon footprint between the technical designs of the stretching machines. Another area of interest is how changes in the parameters of the most important contributors affect the carbon footprint.
