Grade

Fibre & Staple

Line or tow, long-staple or blended. Flax grade decides the yarn before any weave is chosen, and with it the lustre, the strength and the price per metre. Linen is graded at the fibre, not the finish.

Predicting Wet Bundle Cohesion Limits from Pectin Degree of Esterification

Flax wet bundle cohesion limits depend on pectin esterification, where levels between 38 and 48 percent optimize drafting resistance and yarn count.

Weave

Structure & Pattern

Plain, twill, jacquard, damask. The weave carries the identity of the cloth and its loom time; pattern complexity is a cost question and a capacity question at once. Structure first, styling second.

Origin

Provenance & Trace

Origin is what the linen buyer actually pays for. European Flax, Masters of Linen, field-to-fabric traceability: provenance is documented at every stage or it does not exist. This is the qualification gate.
