Monitoring of the ginning process - Uster Technologies

THE STANDARD FROM FIBER TO FABRIC
Moisture of cotton is critical when decisions are being made to optimize the
dryer settings. The final bale moisture sensor also allows the ginners to see
the results of any supplemental moisture restoration system. Research
shows that optimum moisture level in a bale is 7.5%, matching USDA conditions
for classing cotton. Achieving this balance depends on accurate
measurements throughout the ginning process (Fig. 21).

4 Field Test
During a field test, we have taken cotton from the same cotton field. The
yield has been made under the same conditions and the same amount of
raw material has been processes first time by using (active) the USTER ®
INTELLIGIN and the second time without using (passive) the USTER ® IN-
TELLIGIN.
These cotton bales are tested by using the USTER ® HVI. When we look at
the percentage of the total measured bales which are ginned with the
USTER ® INTELLIGIN, the fibers shorter than 34 mm are only 1%. The
bales which have fiber lengths of 37 mm or more have a percentage of
70%. On the contrary, the bales which are ginned without the USTER ® IN-
TELLIGIN have generally lower mean length values (Fig. 22).
