Fundamental Linen Lea Conversions and Metric Yarn Calculations
Linen Lea converts to Metric count via NeL multiplied by 0.604772, while direct Tex equals 1653.52 divided by NeL, adjusted for 12% moisture regain.
Commercial Regain Iso 2060
Moisture Allowance
Moisture allowance standards establish the permissible water content in a textile consignment for transaction purposes. Commercial transactions in flax yarns rely on commercial regain iso 2060 to calculate the invoice weight from the oven-dry weight. This baseline prevents disputes arising from ambient humidity shifts during transit from Chinese spinning mills to global buyers.
The laboratory records this value on the moisture test certificate before export.
Standard Value
The internationally recognized moisture percentage for flax yarn stands at twelve percent under this laboratory specification. Technicians extract yarn samples from the packaging hall of the Chinese spinning mill and dry them to a constant weight at one hundred and five degrees Celsius to establish the dry mass. This protocol excludes environmental moisture variation from the physical trade weight to ensure consistency between different laboratory locations.
The resulting oven dry mass is then adjusted by adding the specified twelve percent regain to calculate the commercial mass. This commercial mass is recorded on the mill’s export invoice.
Contract Adjustment
Commercial weight calculations govern the final invoice price when shipments undergo testing before dispatch. If the actual moisture content exceeds twelve percent, the buyer receives a proportionate discount on the shipped volume. When the yarn is drier than the limit, the seller may adjust the invoiced weight upward.
These adjustments are documented on the official weight certificate.
