How is Piñayarn® made? 

This next-gen fabric is created in a closed-loop production ensuring zero waste, with the pineapple leaf fibres used to make the textile sourced from agricultural discards – requiring no extra land, water or pesticides.


Ananas Anam uses a unique proprietary method to process the pineapple leaf fibres to textile grade, with no bleaching, no pulping and no dyeing. An enzymatic wash is used to remove impurities without using any harmful chemicals, while the rest of the process is fully mechanical. Innovative technologies are used to extract and blend natural filaments with other plant-based materials, repurposing leaves that would usually be burnt after harvest.

How does Piñayarn® help the environment?  

By reducing the amount of pineapple leaves being burnt, Piñayarn® saves the equivalent of up to 6 kg of CO2 emissions from being released into the atmosphere per 1 kg of yarn produced.
