Petit Pli
A patented, bi-directionally pleated fabric that expands through seven sizes, so clothing grows with the child instead of being thrown away. The pleat has a negative Poisson's ratio - stretch it one way and it grows the other - and the fabric is 100% monofibre and recyclable.
What began as a kitchen-oven prototype is now an internationally recognised materials technology and textiles company.
