Saxion.
  6. 6. Chair – Functional smart materialsKey research area Functionalisation of textile materials Inkjet printing / Digital processes Conductive yarns/ 3D prototyping Sustainability: from materials to processes functions Recycling Application of enzyme technology material surface engineering characteristicsKom verder. Saxion.
  7. 7. What are smart-technical textiles? Textiles Materials Electronics Conventional Textiles Technical Textiles Smart/Intelligent TextilesKom verder. Saxion.
  8. 8. Key European projects (FP7) – Smart functional textiles / Digital workflows • Leapfrog (www.leapfrog-eu.org) • Digitex (www.dappoloniaresearch.com/digitex/home.php) • BIOTEX (www.biotex-eu.com) • CONTEX (www.context-project.org) • ProeTEX (www.proetex.org) • STELLA (www.stella-project.de) • OFSETH (www.ofseth.org) • myHeart (www.hitech-projects.com/euprojects/myheart) • Avalon (www.avalon-eu.org) • Clevertex (www.clevertex.net) • Lidwine (http://cordis.europa.eu)Kom verder. Saxion.
  9. 9. Digital workflow Key components • Information/ knowledge flow • Materials flow The nature of Digital workflows • Adoptive system: it adapts to changing conditions by target- oriented responses so that particular function can be performed. • Anolog-digital control / Hybrid control: when a master controller operates on an underlying analog cycle sequence to achieve a high degree of long-term constancy.Kom verder. Saxion.
  10. 10. Why Digital workflow? • European textile sector: need for bulk production to mass customisation. • Market positioning of high performance & functional clothing. • Fundamental redesign of the entire garment industry chain. • Minimising accidents during the production. • Improved precision, reducing mistakes. • Value addition. • Sustainability. • Recyclability. Key DriversKom verder. Saxion.
  11. 11. Technology drivers for Digital workflows Technology • Nano ProductsScience • Bio• Physics • Polymer Production• Chemistry • electronics Market• Technical • ICT Systems €• ……many others • Production • ..many others “Enablers” Social trends and themesKom verder. Saxion.
  12. 12. Digital printing Decrease in rotary screen printing (will go slow because of install base) 50 (% of printed textile volume) In use 25 10 0 1980       1990      2000       2010      2020       2030     2040Kom verder. Saxion.
