Designers nowadays are increasingly making use of animal and vegetal materials in order to create radical new design concepts. (Micro)organisms, such as fungi, bacteria and algae, can be used to either make, improve or infect textiles, resulting in a ‘living’ textile which has not been produced mechanically, but has ‘grown’. During the Spring Symposium 2015 Bio-design in textiles the Textielcommissie.nl will address new developments in the area of biotechnologically manufactured textiles. How will these textiles affect us? And are we able to control fungi and bacteria?
