Filament Length Single Cocoon Meters
Estimate single-cocoon reeled filament lengths from turns/circumference with per-sample measured slip and unrecorded leader correction; distinct from mass/denier linear density.
Description
Reel turns measure filament travel only through a circumference and slip calibration.
Reel turns measure filament travel only through a circumference and slip calibration. Unrecorded leader length adds a separate correction.
Estimate single-cocoon reeled filament lengths from turns/circumference with per-sample measured slip and unrecorded leader correction; distinct from mass/denier linear density.
When to use Filament Length Single Cocoon Meters
Use this tool to estimate single-cocoon reeled filament lengths from turns/circumference with per-sample measured slip and unrecorded leader correction; distinct from mass/denier linear density.
Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.
How to use Filament Length Single Cocoon Meters and understand its results
- Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.
- Enter reelTurnCounts, reelCircumferenceM, unrecordedLeaderLengthsM, measuredSlipFractions using the field table and calculation rules, then run the tool.
- Read estimatedFilamentLengthsM, meanFilamentLengthM. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| reelTurnCounts | Reel turn counts | list of number | Required |
| reelCircumferenceM | Reel circumference m | number | Required |
| unrecordedLeaderLengthsM | Unrecorded leader lengths m | list of number | Required |
| measuredSlipFractions | Measured slip fractions | list of number | Required |
Align nonnegative integer turns, slip fractions in [0,1] and nonnegative leaders with positive circumference. Return corrected sample lengths and their arithmetic mean.1
Paired lists must be nonempty and have equal lengths.
length = turns × circumference × (1 − slip fraction) + leader Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| estimatedFilamentLengthsM | Estimated filament lengths m | list of number |
| meanFilamentLengthM | Mean filament length m | number |

}Limitations and assumptions
This estimates length, not linear density or full cocoon filament recovery.
Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Denier From Length Weight: Infer filament denier as grams per 9000 meters, returning sample values and length-weighted pooled linear density; redundant denier/tex conversion aliases excluded. For a complementary task, use Reelability Percent: Report distinct length-weighted continuous reelability and count-based caller classifications; partial reeling is allowed even for a cocoon classified unreelable by the caller method.
