Masters of Linen™ certification

1. What is Masters of Linen™ ?

Masters of Linen™ is the guarantee of traceability of linen made by European companies on European and Euromed 1 sites. A textile of excellence, local at all stages: from the vegetal European Flax™ fibre, to the yarn and fabric.

Masters of Linen™ is an internationally registered trademark by the Alliance for European Flax-Linen & Hemp and its subsidiary CELC DEVELOPPEMENT.

Masters of Linen™ brings together and promotes certified European textile companies (spinners, weavers and knitters) who wish to offer their customers - brands and/or consumers - a differentiation tool with high added value. 

Masters of Linen™ meets the expectations of consumers and companies in terms of origin and traceability:

  • Masters of Linen™ certified yarns and fabrics are manufactured by certified European companies, from certified European Flax™ fibre. 
  • The European Flax™ fibre is the raw material sourced 100% by Masters of Linen™ certified spinners. Masters of Linen™ certified companies and products (yarns and fabrics) thus benefit from the environmental advantages of the European Flax™ fibre, which is produced through farming that is respectful of the environment.
  • The Life Cycle Assessment (LCA) of the European Flax™ scutched flax fibre is available and under development for the following stages carried out in Europe including spinning, weaving and knitting.

In addition, companies certified as Masters of Linen™:

  • Promote local agricultural and textile know-how 
  • Support European jobs
  • Are subject to strict European regulations on labour and human rights.
  • Offer a high level of service to their customers
  • Guarantee excellence and innovation

The Masters of Linen™ certification guarantees independently verified traceability for yarns and fabrics made from pure linen or containing a minimum of 50% linen.
