Spinning Potential — Based on test results, the anticipated quality of
yarn after it is spun.
Standard Values — Values assigned to the calibration samples of
fiber.
Status —
The menu where the parameters that affect the program
components are defined. The items on these menus are normally
defined when the system is first set up and remain unchanged
indefinitely.
Str — The abbreviation for Strength that appears as a report header.
Strength — The relationship of the breaking force to the mass of fibers
broken, corrected for Micronaire and modified by the calibration
constants. The units match the standard values entered for calibration
cottons, typically grams per tex (g/tex).
Strength @ % Elong — The percent elongation at which a secondary
strength measurement is made for mm fibers.
Stress-Strain Curve — A graphical representation that shows the
relationship of the sample's change in dimension to the force applied
and the magnitude of the force.
Subdirectory — A logical division of the disk drive used so that files
can be grouped together for easier access.
T —
The abbreviation for Trash tat appears as a report header.
Test — A measurement, either a single observation or the average of
several observations, taken by the instrument on a sample.
Test Series — A group of tests performed on a sample (i.e. Color,
Trash, Micronaire, Length, Strength, Uniformity, and Elongation tests
performed on samples).
Trash — The non-fiber portion of cotton. It consists of stems, hulls,
whole or parts of seeds, motes, grass, sand, dust, oil from machinery,
etc. Using the video camera, all areas darker than a threshold level are
counted as trash. The discrimination between trash and background is
