Piñatex Fibre {Ananas Anam} (contains data for tanning, drying, finishing)

The process of manufacturing Piñatex® is composed by several steps. Which initiates with the extraction of the fibres from the leaves (decortication) a semiautomatic process, where the fibres are separated from the leaves by a mechanical process. Followed with a purification step that is based on a biochemical treatment to eliminate the impurities that remain in the fibre after the decortication stage. Then the pineapple leaf fibres are cut, carded and blended with polylactic acid PLA, through a non-woven mechanical process (cross-lapped/Airlaid and needle punching) to get the substrate named as Piñafelt. Then Piñafelt® is pigmented and coated with a PU based resin than complies 10% of the material, by direct-coating technology, this process consists on an impregnation, 2 basecoats and a top coating. https://www.ananas-anam.com/
