♦
Uniformity Index
– The ratio, expressed in percent, of two
length measurements.
♦
Strength
– The relationship of the breaking force to the mass of
fibers broken, corrected for MIC and modified by calibration
constants.
♦
Elongation –
This is the distance to the maximum stress-strain
curve, less the distance attributed to crimp, multiplied by 100
and then divided by the break gage (1/8 inch).
♦
SFI
(Short Fiber Index) – This value is measured from the
Fibrogram curve.
♦
SCI
(Spinning Consistency Index) – This value is derived from
Length/Strength, MIC and Color/Trash
(if measured)
.
♦
Maturity
– This value is derived from L/S and MIC data.
♦
Micronaire
(MIC) – Micronaire value must be determined
before Length, Strength, Uniformity, and Elongation.
The following items are displayed if the corresponding options are
installed and selected:
♦
Leaf Grade
– This value is related to the trash area and particle
count.
♦
Moisture
– This value is measured from the cotton sample.
♦
UV
– This value is measured by the 380 Fibroglow and
measures fiber fluorescence.
(optional)
♦
NEPS
– This value is measured by the 720 NEP Tester and
measures neps in cotton fibers.
(optional)
♦
Rd
– This field contains the color test results for %Rd (lightness).
The three-digit Rd number represents the average of the color
observations for Rd.
♦
+b
– This field contains the color test results for +b (yellowness).
The three-digit +b number represents the average of the color
observations for +b.
♦
Color Grade
– This value is measured by the Color Module
and can consist of up to four alphanumeric characters.
