Nonwoven Materials & Technical Textiles worked example

Meltblown Throughput at 99% expected die uptime: a worked example

What does the result look like when expected die uptime reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when meltblown throughput in nonwoven materials and technical textiles is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Meltblown output per beam cycle: 4 units / cycle (unchanged)
  • Available meltblown cycles in window: 480 cycles (unchanged)
  • Expected die uptime: 99 % (raised for this scenario; the documented default is 90)
  • Expected first-pass yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross meltblown throughput capacity = meltblown throughput output per cycle × available meltblown throughput cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good meltblown throughput capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross meltblown throughput capacity.
  • At this operating point the engine returns 19.2 units for meltblown throughput downtime loss.
  • At this operating point the engine returns 57.02 units for meltblown throughput yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected die uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • A figure at this level is achievable when expected die uptime is genuinely sustained, not just peaked for a shift. It assumes a steady output per cycle; meltblown basis weight and defect rates can swing with polymer lot and die condition, so refresh inputs as the line drifts.

Results at a glance

  • Good meltblown throughput capacity: 1,844 units (headline result)
  • Gross meltblown throughput capacity: 1,920 units
  • Meltblown throughput downtime loss: 19.2 units
  • Meltblown throughput yield loss: 57.02 units
