Fiber diameter distribution
Mean diameter, CV%, and D10/D50/D90 for wool, synthetic, and nanofiber, measured from the image.
Example outputs shown for illustration. Numbers depend on your samples and protocol.
What you get
The measurement, today
Microprojection diameter is read off a projected image by hand, a few hundred fibers at a time. It is slow, it drifts between operators, and the distribution tails are the first thing lost.
What it costs
Fiber fineness sets yarn hairiness, handle, and how readily a fabric pills. Wool a micron coarser than specified changes both the price and the product, and it is the tails of the distribution, not the mean, that generate the complaints.
From image to reviewed result
- 1
Image the fibers
Load microprojection, optical, or SEM images of a prepared fiber snippet slide.
- 2
Calibrate the scale
Set pixels-per-micron against a stage micrometer or scale bar so diameters report in real microns.
- 3
Segment and measure
Each fiber is segmented and its diameter measured perpendicular to the fiber axis; crossing fibers and border objects are excluded.
- 4
Read the distribution
Export mean, standard deviation, CV%, D10/D50/D90, the histogram, and the per-fiber table.
Scope: Automates the diameter measurement that ASTM D2130 performs by microprojection, and applies to any fiber with a round cross-section. Scale calibration and conformance for acceptance testing remain your lab’s responsibility.
