Banana fiber is extracted from the outer layers of the banana plant’s pseudostem — the trunk-like part that remains after the fruit is harvested. This fibrous material is typically considered agricultural waste, making its use in textiles a form of upcycling. The fiber is mechanically processed, requiring little to no chemical treatment, and can be spun into yarn or felted depending on the application.

Banana fiber is naturally strong, lightweight, and biodegradable. It's used in fashion (especially for accessories and structured garments), as well as in home textiles, paper, and craft materials. It has a slightly lustrous finish and is sometimes blended with other natural fibers to enhance softness and flexibility.
