Efficiency Metric
Proportion of raw material that is wasted or discarded during the transition from fiber to finished textile or garment represents a fundamental measure of process efficiency. This metric, known as yield loss percentage, calculates the difference between the weight of incoming material and the weight of the final usable output. It is used by textile mills and garment factories to evaluate the efficiency of their manufacturing lines.
Lowering this percentage directly increases the profitability of the operation.
Production Factor
Wastage occurs at multiple stages, including yarn spinning, knitting, dyeing, and panel cutting. Fabric defects, sewing errors, and left-over fabric scraps from cutting contribute to this total loss. Each process must be optimized to minimize waste.
Financial Implication
A high yield loss percentage increases the cost of goods sold because more raw material must be purchased to produce a given volume of finished garments. This loss must be factored into the initial cost sheet to avoid unexpected deficits.
Reduction Strategy
Factories reduce this loss by employing advanced marker-making software that optimizes panel layout and minimizes fabric scraps. Regular training for workers and maintenance of machinery help prevent errors that lead to discarded materials. Continuous monitoring of waste helps locate problem areas.
