Wondering what lyocell, modal, and viscose are? They’re biodegradable fabrics made from wood pulp. Although, they are not sourced and made in the same way and that makes a big difference in sustainability.
Lyocell, modal, and viscose are made from wood pulp (eucalyptus, oak, bamboo, birch). The pulp is broken down with chemicals into cellulose and then filtered through a process called spinning which makes the fibers. The process of making lyocell, modal, and viscose is not totally man made or synthetic. If you think comparatively, these fabrics fall between silk (natural) and polyester (manmade). The term used to describe them is semi-synthetic.
These wood pulp fabrics are quite breathable, soft to the touch, mostly wrinkle free, and great at moisture management.
Sustainability
Lyocell = yes
The Austrian company, Lenzing, makes lyocell (branded as Tencel) from fast growing eucalyptus tree plantations. They also use a less toxic solvent AND collect over 99% of it back to use again and again. This makes the production of Lyocell a closed loop and more sustainable.
This makes Lyocell a bit more expensive than viscose and modal. Also, the chemicals used to make the fiber creates a slightly more delicate garment when it comes to washing – so wash in cold water and hang to dry. It’s more sustainable than using a dryer anyway!
Viscose and Modal = not really
The production of viscose and modal also uses wood pulp as described above. However, care is not taken to source the materials sustainably and old growth and endangered forests are used. Another concern is the use of harmful, toxic chemicals which are not reused and are released into the environment. The end product may seem like, and have a lower price tag than Lyocell, but does that make it a good product?
My Bottom Line
If you’re like me and shop used/preworn/resale then you can buy any material as you’re helping keep items out of the landfill. and preventing the further destruction of our ecosystem. However, if you’re someone that loves new clothes, then consider making a choice that is significantly better for the planet. You’ll love the look and feel of the fabric, too.
