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.
Finished Fabric Yield
Production Efficiency
The calculation of finished fabric yield establishes the ratio between the weight of grey cloth entering the wet processing stage and the weight of the final textile product ready for export from the Chinese linen mill. This finished fabric yield monitors mass loss during scouring, bleaching, and dyeing operations. Fibre characteristics such as pectin content in raw flax determine the baseline for expected shrinkage.
Technical teams record these figures on the mill production log to track chemical extraction and moisture content variances.
Loss Quantification
Variability occurs when high temperatures or excessive agitation cause mechanical fibre damage during finishing. Each processing step alters the fibre structure and results in a predictable decrease in total mass compared to the initial loom state. Engineers adjust the input parameters to maintain consistency when specific loom states show unusual variance.
A tight margin between the raw input and the final output signals stable chemical control throughout the aqueous treatment.
Contractual Compliance
Acceptance criteria often dictate the minimum output weight allowed for a standard meter of linen cloth shipped to international buyers. Mills provide these records as verification for commercial invoices to ensure buyers do not pay for weight lost to unnecessary chemical runoff. Disputes arise if the actual mass falls below the tolerance levels defined in the initial procurement agreement.
Accurate documentation of this metric separates the physical loss of material from the inherent quality grade of the textile.
