Hydration Level
A standardized percentage represents the amount of water a lot of long flax fibres is expected to retain under normal atmospheric conditions. For international trade, scutched long flax regain provides a fixed reference point to calculate the commercial weight of the material. This figure accounts for the natural hygroscopic properties of the linen plant, which absorbs and releases moisture based on the surrounding environment.
Commercial Application
Contracts often set this value at twelve per cent to ensure consistency across different regions and climates. When a mill receives a bale, they use the scutched long flax regain to adjust the invoice so that they are not paying for water weight gained during a damp sea voyage. This normalization allows for a fair comparison of prices between suppliers in different countries.
Without this standard, the mass of a flax lot would fluctuate too much for reliable accounting. Large spinning operations use these figures to estimate the total yield of yarn they can expect from their inventory.
Measurement Technique
Testing involves weighing a sample in its current state and then weighing it again after it has been completely dried in a specialized oven. The difference between these two weights, expressed as a ratio of the dry mass, determines if the scutched long flax regain matches the contract terms. Precise laboratory equipment is needed to ensure the results are valid for financial settlement.
