Output Calculation
Calculation of fabric length produced per unit mass of yarn or raw material establishes production efficiency and material consumption efficiency in textile mills. Linear metre yield measures the number of running meters of finished fabric obtained from one kilogram or one hundred kilograms of input fiber or yarn. The metric governs cost accounting, yield management, and inventory planning in weaving and knitting plants, stopping when fabric is bought or sold solely on a mass basis without width considerations.
Usable fabric width, fabric weight, and selvedge waste directly determine final yield numbers.
Width Variable
Usable fabric width inversely impacts linear output for a fixed mass of raw material. Broader fabric widths yield fewer running meters per unit mass, even though total area produced remains identical. Finishing stenter adjustments regulate cuttable width to optimize linear yields.
Process Optimization
Mills control yarn waste during warping and weaving to protect yield margins. Fabric density adjustments alter linear yield without modifying raw material input costs. Monitoring mass variations across production lots prevents yield losses during batch processing.
Commercial Accounting
Garment markers require accurate linear yield data to calculate marker efficiency and fabric consumption per garment. Discrepancies between expected and actual yield alter unit manufacturing costs. Purchase contracts specify minimum linear yield values for commercial fabric deliveries.
