3. SMART TEXTILES?
CEN TC248 WG 31
̶ Functional textile material: gets specific properties by dedicated treatment
̶ Smart textile material (intelligent textile material): interacts actively with its
environment (responding or adapting to changes)
̶ Adaptive textile material: senses stimuli from its surroundings, provides
adaptive, reversible response

4. SMART TEXTILES
̶ Body
̶ Environment
̶ Textile itself
