How Do We Know What Textiles Are Sustainable?

Finding sustainable brands

When it comes to making sustainable claims on clothing and other textile items, things start to get confusing pretty quickly. Governments and standards organizations do have documents which outline proper fibre content labelling [1] and “self-declared” environmental claim [2] definitions and requirements, but these documents are often highly technical (boring) and inaccessible ($180 just to read it??). So where do consumers turn to get reliable information on the products they purchase? 

One helpful resource is the Textile Exchange, a nonprofit which has created numerous standards for the certification of claims such as the Global Recycled Standard (GRS), has excellent educational resources on “preferred” fibre advancements, and has created the Material Change Index (MCI) to show how over 100 brands are performing in key areas. Of course, organizations like this and the similar Sustainable Apparel Coalition (SAC) cost money to be a part of, which excludes many smaller businesses and startups from having the same visibility. When looking at smaller more independent companies, keep an eye out for any claims they’re making, and whether those claims can be substantiated. Are they claiming their product is “sustainable” without any explanation as to why? Do they discuss why they’ve chosen specific materials? Do they talk about who makes their products and if those craftspeople are being paid a living wage? A great example of this is from the Canada/US/Ghana-based company Osei-Duro.

What Are Textiles?

What are textiles?

What do we mean when we’re talking about textiles?

Textiles refer to flexible materials made of polymers, films, fibres, yarns or fabrics [1]. Many items we interact with daily are textiles: clothing, bedding, towels, furniture upholstery, personal protective clothing or equipment, etc. Textiles can be made of natural fibres such as cotton, wool, and silk, regenerated fibres like lyocell or acetate, or of synthetic fibres like polyester, nylon, and acrylic. 

Our clothing is made up of fibres that have been spun into yarns and woven or knitted into fabrics. Alternatively, clothing can also be non-woven as is the case with felted fabrics or leather. The fibre content, yarn type, fabric construction (woven, knit, or non-woven) and construction of a textile product will all influence aspects such as the function, comfort, appearance and durability of the item. For example, rain jackets are typically made from synthetic fibres with yarns that are tightly woven for water resistance while cotton t-shirts are knitted for greater stretch and comfort. Therefore, choosing a garment that is suitable for a particular function or activity can help your clothing last longer.

Our goal is to help you understand what textiles are, how they’re made, and how those fibres/processes affect the end product and its impact on the environment.
