These are the textiles used in the last three collections. To find out more about certifications of each fabric, check out "our standards" page.

Viscose (ECOVERO) 

At Residus, we love ECOVERO. Manufactured from only certified sustainable wood, plant-based viscose provides a great alternative to harmful viscose textiles. Eco-viscose fabric is a soft fabric and is easy to wash. 

Organic Cotton 

Cotton is a natural fiber that is spun from a cotton plant. It is made into thread and creates a soft, breathable fabric. Cotton is an essential when it comes to creating garments, and we only use organic! 


Silk is an all-natural, eco-friendly fiber made by insects such as spiders or silk worms. The fabric’s strength comes from a protein called fibroin while a protein called sericin gives silk its surface protection. At Residus, we always use surplus silk and ensure its ethical production.


Triacetate is a semi-synthetic fiber made from acetate and cellulose pulp from wood. The fiber creates a shrink and wrinkle resistant fabric which dries quickly. Triacetate has a silky feel and drapes well. 


Polyamide, otherwise known as nylon, is a synthetic, oil-based fiber. Polyamide is wear-resistant and maintains the fit very well. Because polyamide is a synthetic fiber, we only use a very small amount in our products. 


Polyester is an oil-based synthetic fiber. It does not wrinkle, it is easy to care for, and keeps its shape well. Polyester is often mixed with cotton, wool and viscose. All of the polyester we use is surplus and azo-free. Going forward, we are working to cut out all polyester from our garments. 


Elastane, or lycra, is a synthetic stretch fiber known for its high elastic capacity. Elastane is never used alone in a garment; as little as two percent of elastane may be enough for the garment to keep its shape better.
