This document provides information about the USTER HVI 1000, a high-volume instrument used to measure important cotton fiber properties. It measures 10 properties including micronaire, maturity index, short fiber index, fiber strength, elongation, moisture content, color, trash percentage and grade, and spinning consistency index. There are five global companies that manufacture these types of rapid testing machines, including USTER Technologies. The USTER HVI 1000 uses a computer system, balance, printer, and optional barcode reader or UV/NEP modules. It measures properties through airflow resistance, optical length measurement, and clamp strength testing. The results are operator independent, based on large samples, provided quickly in summarized reports.

3. HVI
HVI means high volume instrument . USTER HVI 1000 is
produced by world famous USTER company. The USTER® HVI
1000 measures the most important cotton fiber properties for
cotton classing purposes.USTER® HVI 1000 is the global
reference tool for cotton classification, producing accurate and
reliable results.

9. • Measurements and Calculations
• Micronaire: Micronaire Reading . Measured by relating
airflow resistance to the specific surface of fibers.
• Maturity: Maturity Ratio . Calculated using a sophisticated
algorithm based on several HVI™ measurements.
• Length: Upper Half Mean Length, Uniformity Index, Short Fiber
Index Measured optically in a tapered fiber beard which is
automatically prepared, carded, and brushed.
• Strength: Strength, Elongation Strength is measured physically
by clamping a fiber bundle between 2 pairs of clamps at known
distance. The second pair of clamps pulls away from the first pair at a
constant speed until the fiber bundle breaks. The distance it travels,
extending the fiber bundle before breakage, is reported as elongation

11. 1. The results are practically independent of the
operator.
2. The results are based on large volume samples, and
are therefore more significant.
3. The time for testing per sample is 0.3 minutes.
4. About 180 samples per hour can be tested and that
too with only 2 operators.
5. The data are clearly arranged in summarised reports.

12. • 100% cotton samples in the form of bale
or opened and cleaned material (card
mat).
• Spinning Consistency index (SCI)
