5 Sustainable Fabrics in Ethical Fashion and Sustainable Design

Sustainable Fabrics

TL;DR This article dives into five sustainable fabrics: piñatex, Tencel, cupro, hemp, and upcycled fabric. We share what each fabric is, how its made, and the brands using that material in their collections.

Sustainable textile innovation is happening at a rapid pace. New fabrics entering the market are both far more ecologically sustainable than existing options and have better performance qualities. Piñatex, TENCEL, Cupro, hemp, and upcycled fabric are just a few of these innovative textiles.


We proudly carry many products using these impressive materials in our curation of ethically elevated goods. Below, we will dive into five sustainable fibers and share some of our favorite brand partners using these earth-friendly materials.




TENCEL is an impressive sustainable fabric utilizing environmentally sustainable production processes from Austrian manufacturer Lenzing. TENCEL has great performance characteristics and is lightweight, smooth, soft, and durable, retaining its quality wash after wash. It’s uniquely smooth surface also makes it absorbent, hygienic, and breathable.


Behind the Process


Upcycled cotton scraps from clothing factories are blended with eucalyptus wood pulp sourced from farms certified by the Forest Stewardship Council (FSC). This environmentally responsible process recycles an incredible 99% of the solvent for the next batch, creating a closed-loop process.

Banana Fabric


Banana fabric is an eco friendly fabric alternative made from the stems of banana trees and has a beautiful, natural shine that makes it a wonderful plant-based and vegan alternative to silk. Because bananas can only be harvested from banana trees once in their lifetime, tree stems are often discarded after harvesting, leading to massive amounts of waste. By repurposing the banana tree stems to create silky smooth banana fabric, waste is successfully minimized within the banana industry while also providing extra income and opportunities for the communities that grow bananas.


Behind the Process


Banana fabric can be made using many different methods. The most popular method is to simply strip apart the sheaths of the banana stem and process it into yarn. Another way is to strip off the layers of the banana stem sheath with a knife until only the fibers are leftover. The fibers are then naturally dried and knotted and twisted together to create banana fabric.

Hemp is among the most sustainable crops to grow — it grows quickly, doesn’t require herbicides or pesticides, and needs very little water. Additionally, since hemp grows densely, farmers can yield more hemp per hectare or acre than other crops, such as cotton.


Behind the Process


After cultivating the hemp plant, the fibers from the plant stalk are extracted using a process called retting. Retting breaks down the pectins that bind the hemp fibers together. Once these hemp fibers are released, they are spun into thread and woven into hemp fabric.

Ma Wovens


Ma Wovens creates their sustainably made yoga mats from naturally antimicrobial organic hemp and non-toxic foam. The rug can function as a grippy, non-slip yoga mat or as a runner rug in your kitchen and living spaces. The rugs are handwoven by Good Weave Certified artisan partners in Northern India, ensuring the makers behind Ma Wovens’ products are paid fair, living wages.

Upcycled Fabric


Upcycling is the process of reusing material to create a product of higher value. This is generally preferable to recycling (which reuses a material to create something of equivalent value) or down-cycling (which reuses material to create a product of lower value than the original). In terms of fabric, an example of upcycling is when remnant fabric scraps or rolls of deadstock are used for clothing. An example of down-cycling is if the remnant fabric is used as stuffing for sofa cushions.

Piñatex (Pineapple Leather)


Piñatex is a sustainable vegan leather alternative made from pineapple leaves that have been discarded by the pineapple industry. By using by-products of pineapple agriculture, Piñatex “leather” not only reduces waste, but also provides an additional source of income for pineapple farmers.


Piñatex Founder Dr. Carmen Hijosa witnessed the widespread environmental damage of mass leather production in the Philippines. This lead Dr. Hijosa to create a socially and environmentally responsible, non-woven textile that could replicate leather on a large scale while creating a minimal environmental impact. She spent seven years researching and developing Piñatex into the product we know and love today, and she is still involved with the continual improvement of this unique textile.


Behind the Process


After collecting the pineapple leaves, the fibers are extracted using a decorticator, a machine that removes the skin or bark from raw materials such as plant stalks and wood. Nothing is wasted in this process since the leftover biomass can be used as a biofuel or natural fertilizer.

These pineapple leaf fibers that have been extracted are then degummed before being manufactured into a non-woven mesh. The non-woven mesh is then sent to Spain for finishing — creating a flexible-yet-durable material.

The final product is the pineapple leather textile called Piñatex, now used by designers around the world — in footwear, accessories, and upholstery — as an alternative to leather.
