Baseline Measure
The standardized weight of a textile material after removing all moisture by heating constitutes the fundamental baseline for commercial and technical calculations. In commercial flax transactions, the dry mass reference is established to allow mills to separate the actual fiber mass from absorbed water. This standard ensures that buyers pay only for the dry fiber itself.
Oven Process
Drying chambers operated at a regulated temperature of one hundred and five degrees Celsius extract all moisture from the raw flax or linen yarn. This process continues until successive weighings show no further change in sample weight, which confirms that the dry mass reference has been reached. Because flax fibers are highly hygroscopic, the dried sample must be weighed inside a sealed container to prevent the rapid reabsorption of atmospheric moisture.
This protocol guarantees that the measured value reflects the true dry state of the fiber.
Trade Valuation
Moisture content calculations use this dry baseline to determine both the legal invoice weight and the commercial yield of a spinning batch. The dry mass reference provides the starting point for applying the official commercial allowance, which is added to calculate the correct billing weight. Standardized commercial regain values for linen yarn usually sit at twelve percent.
