A breakthrough came when she realized that she could make a non-woven textile, a fabric bonded together without knitting or weaving, from the long fibres found in pineapple leaves. The culmination of her work resulted in the creation of Piñatex, a unique natural and sustainable textile made from pineapple leaf fibres, a by-product from the pineapple harvest.
