Modal fabric is taking the fashion industry by storm and more and more brands are incorporating it into their lineups on and off the catwalk.
But is it ethical and sustainable?
Or is modal fabric another contributor to the destruction of the planet at the hands of an industry not exactly famous for green credentials?
What is modal fabric? It’s a semi-synthetic variation of rayon. It uses beech tree pulp as its based ingredient.
Modal fabric is more durable and will flex better than rayon and it can be used in blends to give it greater strength.
Modal and cotton as well as modal and spandex are quite common uses.
It’s feels super soft to the touch and that means it’s expensive and you will pay more for it than you would for say, cotton or viscose.
The Origins Of Modal Fabric
Modal was originally invented in Japan and it came into use as early as the 1950s.
In 2020, the majority of the world’s modal originates from a single source, an Austrian company by the name of Lenzing AG, which holds the trademark for modal.
You can find different brands of modal from the same company – these include Formatex, China Modal and Lenzing Modal.
The variations tend to be of even higher quality than the standard fabric and yes, they are even more expensive for it.
Is Making Modal Environmentally Friendly?
It’s certainly more environmentally friendly than making cotton.
That’s because beech trees tend to suck up much less water than cotton plants.
It takes around 10-20 times less water to grow the trees than the equivalent amount of cotton plants and that’s clearly good for the planet.
However, modal also incorporates the use of chemical processing.
Though it’s more eco-friendly the use of sodium hydroxide (a bleaching and dissolving agent) and carbon disulfate in the manufacturing means that this is not a “natural” product, it’s a semi-synthetic.
The Risks Of Deforestation
In addition to what we’ve seen about growing and manufacturing modal there are some serious concerns about the impact of modal on the planet.
While many companies that manufacture modal under license deliberately choose to use beech trees that were grown on land that was unfit for all other agricultural purposes – some are less ethical.
If the wood they sourced was from Indonesia it’s entirely possible that rainforest was cleared in order to saw monocrop (that is single tree) timber plantations and that’s definitely not good for the planet.
The Risks To Workers
The sodium hydroxide and carbon disulfate are not good news for workers.
If any animals or, indeed, the workers come into contact with the product while it’s being treated with these chemicals they are exposed to what is essentially a neurotoxin.
The nerve damage that it causes can blind someone, kill them or even, in extreme cases, kill them.
Lenzing Does Better
Lenzing has recently turned Lenzing Modal into TENCELTM Modal. This is designed to be a better product which holds itself to the highest standards.
They want to demonstrate that modal can be sourced from renewable forestland and that the processing was done in a way that is meant to keep emissions to a minimum.
They use an environmentally friendly process which has been certified globally that allows them to better recover the chemicals used in the preparation of the fabric. This reduces emissions and conserves resources.
At the same time, they use trees harvested from sustainably managed plantations in Europe to create the fabric. This means it’s easier to be certain that the trees are ethically sourced.
What is important to remember though is that Lenzing doesn’t directly manufacture any modal textiles. Instead, it produces the yarns and then ships them to factories and textile manufacturers around the world that transform the fibers into fabrics.
Lenzing has no control over the ethics and sustainability of the companies involved in these processes.
Conclusion | Is Modal An Ethical Sustainable Fabric Choice?
So, from what we have learned about modal is that it can be an ethical sustainable fabric choice.
If you’re buying TENCELTM Modal then you know that the initial part of the supply chain was designed with the environment and the well-being of people in mind.
What you still need to do is ensure that you are buying your fashion products from an ethical supplier that is clear about what happens to the TENCELTM Modal once it has left the hands of Lenzing.
