ISO 22095 Mass Balance Allocation Models for Blended Linen Yarn Manufacturing
ISO 22095 mass balance allocation demands dry-mass baselines and process waste reconciliation to stop certified credit inflation in mixed flax spinning.
Noil Loss Ratio
Fibre Yield
Fibre preparation performance measures the proportion of short, tangled fibres removed from the main stream during combing. In flax spinning mills, the noil loss ratio calculates the weight of the short noils extracted as a percentage of the input scutched flax. This metric directly determines the efficiency of the combing process and the yield of the premium long-staple linen yarn.
It acts as an indicator of raw fibre quality and machine calibration. Higher values show that the raw flax contains many short or weak fibres that cannot survive combing.
Processing Efficiency
Combing machines must be tuned precisely to balance the extraction of short fibres against the retention of long fibres. A high noil loss ratio means more flax is downgraded to low-value byproducts, which raises the manufacturing cost of the remaining yarn. Spinners adjust machine speeds to minimize this loss while maintaining yarn quality.
This balancing act requires constant monitoring on the factory floor.
Yarn Grade
Premium linen fabrics require yarns that are spun from uniform, long-staple fibres that have been thoroughly combed. Monitoring the noil loss ratio ensures that the combing process has removed enough short fibres to prevent yarn breakage. This step guarantees that the final woven linen meets the high strength standards demanded by luxury apparel buyers.
