Moisture Regain Adjustment Mechanics in Cross Border Scutched Flax Landed Contracts
Landed flax contracts adjust invoice mass by converting quay scale weights to dry cell wall mass using ISO 6741 oven tests before applying 12% standard regain.
IFTH
Fiber Grading
Flax fibre classification establishes the baseline parameters for raw material acceptance across spinning mills. IFTH operates within this primary procurement stage by setting the physical benchmarks for length, fineness, and tenacity. Quality inspectors record these measurements in the batch intake certificate before the material enters hackling and drawing frames.
Market standards differentiate between short-line tow and long-line line flax through strict tensile thresholds. Buyers reject any consignment falling below the contractual moisture regain limit regardless of supplier certification.
Yarn Tenacity
Spinning technicians monitor intermediate tensile resistance during drafting and ring frame operations. IFTH evaluates the structural integrity of the resulting yarn by applying standard breaking load tests to randomized bobbins. Mill laboratories document these breaking length values on the production control sheet accompanying the package yarn to the loom.
Fine counts demand higher twist multipliers to compensate for reduced fiber surface contact during drawing. Twist irregularity alters the final breaking load distribution across the cops.
Fabric Density
Woven cloth inspection verifies warp and weft counts per centimeter prior to chemical finishing. IFTH specifies the allowable variance between nominal specifications and finished greige goods. Quality controllers log warp sett and weft pick counts in the final inspection report before dyeing and export dispatch.
Fabric grades depend on the absence of foreign matter and broken filaments within the loom state structure. Tensile strength along the warp axis determines commercial acceptance for industrial applications.
