10.5 Initial Category Definition for
Inventory Analysis
Each property has a Category Definition that was set up at the Uster
Technologies factory. However, typically that definition will not
correctly represent your inventory. The purpose of the following steps is
to determine what values to use to correctly define categories for your
cotton.
The following chart should encompass all the values that may be found
in normal cottons. Use the values below to initiate Histograms for each
fiber property according to the procedures outlined in this section. Most
spinners will find that their actual inventory covers a much smaller
range. By using the suggested values for an initial setup to generate
the histograms, you can define the categories to closely represent your
cotton.
Initial Values Chart
Highest Interval Number of
Value of 1st Between Categories
SCI 87 5.00 20
Micronaire 2.2 0.20 20
Strength 18.5 1.00 20
Length (inch) 0.86 0.03 20
Length (mm) 21.8 0.8 20
Uniformity (index) 70.5 1.00 20
Uniformity (ratio) 36.5 1.00 20
CSP 1550 100 20
Rd 46.0 2.00 20
b 4.5 0.60 20
Note: These are not the recommended Category Definition values.
Use these values only in during initial setup in order to study the
distributions of each measured fiber property. To use them, make
temporary changes on the Category Definition screen.
