Measure fabric width utilization in marker layout.
Key formulas: totalLen×effWidth÷100; totalLen×width÷100
| Item | Formula / Rule | Source / Standard |
|---|---|---|
| Efficiency formula | Efficiency = total pattern area / (usable width × marker length) × 100 percent | ISO 22198:2006, fabrics, determination of width and length |
| Usable width | Usable width is below nominal width after deducting selvedge and defects | ISO 22198:2006, fabrics, determination of width and length |
| Width sensitivity | Wider fabric raises efficiency, yet cutting table and equipment limits set the usable maximum | ASTM D3776-20, mass per unit area of fabric |
幅宽排料利用率反映面料幅宽方向的有效利用程度。本工具根据面料幅宽、有效利用宽度、单件排料长度与件数,计算幅宽利用率、布边损耗与总用料,帮助优化排料方案、降低面料损耗。
