      • Production development
  • 3. TNO Centre for Textile Research
    • Located in Enschede
    • 25 employees
    • Member of Expertex
      • Expertise centre for textile research and education
    • Member of Textranet (www.textranet.org)
    • R&D-topics
      • Process innovation
      • Product development
        • Functional textiles (dynamic properties, comfort)
      • Testing
        • quality, performance, durability
  • 4. Process innovation
    • Aim: development of sustainable textile finishing processes
      • conservation of water, chemicals and energy
      • improved durability of textiles
      • improved functionality
  • 5. Towards sustainable processes
    • Enzymatic treatments
      • Desizing
      • Pre-treatment of cotton (FP5)
        • Bio-scouring, bio-bleaching
      • Bio-finishing (cellulase)
    • Environmental benefits
      • 50% reduction of energy consumption
      • 75% reduction of chemical consumption
      • 40% reduction of water consumption
    • Product benefits
      • Better hand
      • Improved durability
  • 6. Water management
    • Activities
      • Reduction of water use in processes (l/kg)
      • Process water quality
      • Waste water treatment
      • Reuse of selected streams
      • Closing the water loop
    • Development of water management tool
      • Calculation on quality of waste water
      • Calculation of environmental impact
      • Scenario studies
        • Craft and national funded project
  • 7. Energy conservation
    • National program on energy reduction
    • 1990-2000: 20% energy reduction realised
      • good house keeping
      • better understanding of processes
        • user groups; bench marking
      • improved equipment
    • 2001-2010: another 20% energy reduction
      • sustainable processes
      • use of renewable energy sources
  • 8. Textile recycling
    • Introducing principles of cascading in textiles
      • reduction of fibre consumption
      • optimising actual and technical life time
    • Identitex (Craft): automated identification and sorting of textile waste
      • improved quality, so better options for reuse
    • Reprotex (Craft, in preparation)
      • finishing and product development using recycled fibres
        • aiming at high added value
  • 9. Strategy FP6
    • Development of sustainable processes by
      • Process integration
        • reduction of fixation, washing and drying operations
        • integrated water and energy recovery
      • Use of environment friendly chemicals
        • enzymes, catalysts
        • bio-chemicals
      • Controlled application technology
        • ink jet, plasma, foam
      • Advanced washing and drying processes
        • CO2?, airless drying
      • Improved process control
  • 10. Implications for workwear
    • Sustainable production of fabrics
    • Improved durability (nano-technology)
    • Functionalities will increase
      • smart textiles, dynamic properties
      • higher comfort level
    • Care will be easier
      • self cleaning fabrics?
    • Co-operation between all stake-holders in textile chain needed in R&D
    • FP6 offers good opportunities; TNO will help
