StarTex – Starch-based textiles made from biopolymers

StarTex stands for innovative developments in the field of bio-based textiles and demonstrates how expertise in materials research, sustainability and technical applicability comes together to create forward-looking solutions for industry and medicine.

Background
The textile industry is increasingly seeking environmentally sustainable materials that are also functional and versatile. The aim of the StarTex project was to develop textiles that are biodegradable and resorbable. Biodegradable fibres are becoming increasingly important in the clothing industry, as conventional, non-biodegradable materials release microfibres with every wash cycle, thereby contributing to the growing burden on wastewater systems and the environment.

Material solution
Through the targeted chemical and physical modification of starch, it was possible to develop a material that can be spun into filaments. These filaments can then be processed into textile structures.

The resulting non-woven fabrics are characterised by biodegradability, resorbability and mechanical stability. These properties open up a wide range of applications – from agricultural and geotechnical textiles through to clothing and medical textiles, where biodegradable materials are in particularly high demand.

Technical advantages
- Development of starch-based filaments for textile structures
- Biodegradable and resorbable
- Versatile applications in geotextiles, agricultural textiles and medical textiles
- Functionality comparable to conventional textile materials
- Alternative to synthetic fibres

Result
The StarTex project demonstrates that functional textiles made from bioplastics are feasible. By combining biodegradable ARBOBLEND® starch compounds with innovative filament technology, materials have been created that not only reduce the environmental impact but can also be used in a wide range of industrial and medical applications.

Project sponsor: The project is supported and funded by the Federal Ministry of Food and Agriculture (BMEL) and the Agency for Renewable Resources (FNR).
