Sustainable fabrics are often made from natural or recycled materials, aiming to reduce harm either through the production process, fiber properties, or overall environmental impact. These fabrics can also contribute to waste reduction, water conservation, lowered emissions, and soil regeneration—though, there isn’t one fabric that is entirely sustainable. So Kupu Kupu takes sustainability serious and we also want to be honest that every choice has is advantages and disadvantages.  



These fibers are produced by environmentally responsible processes from the sustainably sourced natural raw material wood.


TENCEL™ Lyocell is a plant-based fiber with some out of this world capabilities: it’s moisture-wicking, durable, low-maintenance, and naturally inhibits the growth of bacteria. And it’s soft. Like, REALLY soft. TENCEL™ Lyocell is made from Forest Stewardship Council Certified sustainable eucalyptus trees. (Fun fact: Eucalyptus requires fewer pesticides and far less acreage and water to grow than cotton!). Eucalyptus wood pulp is processed with nontoxic solvents in a closed-loop system wherein 99% of the solvents are recovered and recycled. The result? A yarn that’s been certified Oeko-Tex® Standard 100; this certification ensures rigorous testing and auditing to determine environmentally friendly textiles. 

The fibers are certified as compostable and biodegradable, and thus can fully revert back to nature.


Makes sense we want to use this fabric a lot right?!

Advantages of Lyocell, EcoVero and Tencel:

  • It is considered a sustainable fabric because it is made from wood and is therefore, biodegradable and compostable
  • breathable, strong and gentle on skin with a soft, silky texture
  • absorbing moisture
  • Very soft and comfortable
  • Unlike viscose and other types of rayon, it is made using a “closed loop” process which means that the chemicals used in production do not get released into the environment

See. Feel. Touch. Let your senses discern all the benefits of these fabrics. So soft and smooth. So gentle on skin. And so good at absorbing and releasing moisture therefore supporting our body’s thermal regulation.  


We use Tencel Lyocell, Tencel Viscose, Tencel moda, Eco Vero from Lenzing and a blend with lyocell and cotton.



Organic cotton:

Organic cotton needs much less water (due to irrigation systems designed for rainfall) and does not use pesticides in comparison to normal cotton. 


From an ecological standpoint, organic cotton farming uses 62% less energy and 88% less water than conventional cotton. 


Cotton is: Hypoallergenic, breathable, soft, Moisture control, absorbent 


For a few Items we use cotton. If possible we always will use organic cotton. For the knitted items there is no cotton thread available here yet unfortunately and in the blends of material with lyocell there  is also no organic cotton option. 



Linen is another natural fibre we’ve been growing for centuries. It’s derived from a very versatile crop: the flax plant. Linen requires minimal water and pesticides, and even grows in poor-quality soil. Plus, every part of the plant is used, so nothing is wasted. Linen is strong, naturally moth resistant, and, when untreated (i.e. not dyed), fully biodegradable. In addition to being good for the planet, it is also light and can withstand high temperatures, absorbing moisture without holding bacteria. What’s not to like?



It probably won’t come as a shock to anyone that bamboo fabric is made from…bamboo. 

It is one of the fastest growing plants on Earth. 

t doesn’t require pesticides, fertilizers, or irrigation. Just rainwater.

Harvesting it doesn’t actually kill the plant. One can simply saw off the stalls while leaving the roots to resprout.

Bamboo produces 35% more oxygen and absorbs five times more carbon than other types of trees. 


That sounds all really good and sustainable. There is unfortunately also a downside. The process of turning hard bamboo into a soft fabric generally requires extensive processing with chemicals. So that is why we decides not to use that many bamboo fabrics. 

Bamboo fabric is breathable, has excellent moisture-wicking, anti-fungal and antibacterial properties, decent heat retention and a nice drape and a silky texture. 


Viscose fabric is made from cellulose that's been extracted from the bark, wood, or leaves of plants.

We have created two beautiful pieces in viscose fabric. For now we don’t have a more sustainable option. Of course we keep searching for Geen ander alternatief voor de textuur die we zoeken voor deze blouse en jurk in Bali. We blijven zoeken naar een nog meer sustainable alternatief. Die ook tegemoet komt aan de wensen die we hebben voor dit item. 

Viscose is a lightweight material with a nice drape, a lustrous finish, a soft feel and absorbent, moisture wicking, breathable. 


We only use natural fabrics like;
Linen, Viscose, Tencel, and Ecovero Rayon, Cotton. When possible all organic.
