Calculating Raw Linen Greige Off-Loom Mass Loss
Off loom mass loss in linen greige averages 14 to 22 percent, requiring correction for sizing pickup, moisture regain, and non cellulosic scour extraction.
Off Loom Mass Loss
Fabric Variance
Moisture reduction from raw grey goods to finished textile goods describes off loom mass loss. This physical decrease happens when humidity levels drop during the transition from the humidification environment of the loom room to the dryer warehouse air. Factories track this change to ensure the final weight of a shipment matches the contractual agreement signed with the purchaser.
A consistent dry-out period allows for the stabilization of cellulosic fibres after mechanical strain.
Correction Factor
Calculation of this value relies on comparing the weight of a roll immediately upon removal from the machine to the weight after a period of atmospheric conditioning. Standard protocols require weighing the material in an environment where ambient temperature remains near twenty degrees Celsius and humidity stays around sixty-five percent. Technicians subtract the final dry weight from the initial production weight to establish the total reduction.
Deviations from expected norms indicate either excessive sizing content in the original yarn or moisture trapped deep within the fibre bundles during the weaving process.
Production Boundary
Measurement of this phenomenon applies strictly to the interval between the final pick insertion and the departure of the cloth from the mill floor. Textile inspection reports note these values to separate natural weight shifts from inaccuracies in the initial beam setup or shortfalls in linear meterage. Auditors look for these figures when verifying that the mass of delivered flax products aligns with the technical specification sheets provided at the point of sale.
Control over these fluctuations remains the primary mechanism for maintaining inventory integrity across the entire supply chain.
