To cut a long story short, vegan microfiber is generally plastic and with Oeko-Tex 100 certification it's free from significant levels of toxic substances.

OEKO-TEX Standard 100 certified microfiber is primarily made from synthetic, petroleum-based plastics, most commonly a blend of polyester and polyamide (nylon)

While "microfiber" refers to the fineness of the fiber (thinner than 1 denier or 1/100th of a human hair), the OEKO-TEX certification ensures that these synthetic materials have been tested and verified to be free from harmful levels of toxic substances, rather than indicating it is made from natural materials

Core Material Composition:
  • Polyester (approx. 70-80%): Provides the main structure, strength, and moisture-wicking properties.
  • Polyamide/Nylon (approx. 20-30%): Adds density, softness, and high absorbency to the fabric.
  • Recycled Polyester (rPET): Some certified products are made from recycled plastic bottles, although they are still synthetic polymers.

What OEKO-TEX Certification Means:

The OEKO-TEX Standard 100 label indicates that the synthetic fabric has been tested for over 1,000 harmful substances, including:
  • Azo dyes
  • Formaldehyde
  • Heavy metals (In the case of these Nae Vegan brogues they're free from Chromium, which is a common metal used in the leather industry)
  • PVC

It is a health and safety certification (ensuring it is safe for skin contact) rather than an environmental certification, meaning it guarantees the product is non-toxic but not necessarily biodegradable or eco-friendly.

Characteristics:
  • Structure: Under a microscope, these fibers often appear star-shaped or asterisk-shaped, which allows them to trap dust, dirt, and bacteria, making them highly effective for cleaning.
  • Safety: The certification ensures that even though it is plastic, it will not release harmful chemicals into the air, soil, or onto the skin.
  • Durability: The synthetic, high-density weave makes the material highly resistant to tearing and stretching.
