Quantifying Mass Yield Loss in Long Line Flax Wet Spinning
Wet spinning long line flax generates 35 to 40 percent mass yield loss from hackling shive ejection, hydrothermal pectin extraction, and ring frame waste.
Weighbridge Tare Balance
Logistics Verification
Mass measurement accuracy at a mill is maintained through the calibration of the difference between a vehicle’s gross weight and its empty weight. The weighbridge tare balance ensures that the recorded weight of incoming flax straw or outgoing yarn skips does not include the weight of the truck or container. It acts as the fundamental check for the net weight used in commercial invoicing and inventory management.
Operational Standard
Vehicles must be weighed twice to determine the exact quantity of the material delivered to the spinning facility. The weighbridge tare balance accounts for fuel consumption or changes in the truck’s equipment between the two weighing events. Standard practice requires a driver to remain in the cab or stay out of it for both measurements to maintain consistency.
Any discrepancy in this balance can lead to disputes between the supplier and the mill regarding the actual weight of the fiber.
Legal Compliance
Official inspectors certify the equipment at regular intervals to meet national standards for trade. This weighbridge tare balance must remain within the allowed margin of error to be used for legal documents and customs declarations. Frequent testing with known weights prevents the drifting of the sensor readings over time.
