modules Nep Classification
Fiber neps and seed coat neps Count and size distribution
Length and Maturity Length by weight and by number Short fiber content Maturity ratio
Trash Dust Trash Total foreign matter
Nep Module •The nep module individualizes
between neps and seed coat neps
•Each event (fiber, nep, SCN, ) has its own distinct electrical waveform
•Each samples waveform is compared to a standard waveform to determine which classification it most resembles

Fiber Individualizer
It can run up to 30 samples at a time
Fiber Individualizer
Optical sensors/detectors
Length measurement Single fiber measurement
Measured with an opto-electronic sensor
Fiber creates signal/impulse
converted to an electrical signal
analyzed and evaluated by computer
Trash & dust measurement
Separate sensor
Same measurement principle as for the length &nep measurement
Short Fiber Content
initially, the fibers have more or less the same length length is reduced with any mechanical treatment (
harvesting, ginning, opening, cleaning)
mainly reduced at combing
Maturity Module
Maturity ratio Fineness Immature Fiber Content Summary table and histograms
Fiber Maturity Measurement
AFIS measures the fiber shape Each fiber is measured from two
different angles by the optical sensor
Depending on the shape, cotton fibers are divided into: Fully mature -typical convolutions
of a mature fiber Immature -less obvious
convolutions, more flat Dead -no convolutions,
completely flat, “ribbon like”
