Materials

What a fiber label tells us, what it leaves out, and how to read a material claim.

A label is a starting point

A fiber label tells you composition. It does not tell you where the fiber came from, what happened during processing, which electricity powered a mill, how a worker was treated, or how many times a garment will be worn. Those missing details are often central to an environmental or social claim.

Compare like with like

Questions worth asking include: what is the fiber source, what processing was used, what is the product designed to do, and how long is it expected to last? An assessment that compares one kilogram of fibers is different from one that compares garments delivering the same years of use.

Textile Exchange’s Materials Matrix compares material programs within categories and documents the practices and impact areas each covers. It is a useful route into evidence, not proof that every product using a named material performs equally.

Three useful checks

  • Trace the claim to its actual certificate, study, or supply chain record.
  • Check whether it covers a fiber, a facility, or the finished product.
  • Look for tradeoffs and missing stages, especially dyeing, finishing, and use.
