Fabric Relaxation Time at 12% setup, handling, and delay allowance: a worked example

This scenario runs the fabric relaxation time calculation on the strong side: 12% setup, handling, and delay allowance, with every other input held at its documented default. Use it when fabric relaxation time in textiles and apparel manufacturing is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Total fabric length to relax (roll batch): 120 units (unchanged)
  • Fabric feed rate through relaxation table: 12 units / min (unchanged)
  • Setup, handling, and delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base fabric relaxation time = fabric relaxation time workload รท fabric relaxation time completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required fabric relaxation time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base fabric relaxation time.
  • At this operating point the engine returns 12 % for fabric relaxation time allowance applied.
  • At this operating point the engine returns 12 pieces / min for fabric relaxation time completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it when sequencing a spreading line or committing a cut date, so relaxation is finished before the marker is laid. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Required fabric relaxation time: 11.2 hr (headline result)
  • Base fabric relaxation time: 10 hr
  • Fabric relaxation time allowance applied: 12 %
  • Fabric relaxation time completion rate: 12 pieces / min
