A
good quality combed sliver will have only 1 or 2 neps per
gram. Therefore, unless we measure with an adequate sample
size, the
results would be highly variable. Higher the sample size,
less the error. Premier aQura provides the most reliable and
accurate nep values with a very low variability in the results
by testing a sample size of 5 to 10 g within a time of 3 minutes.
Accurate
categorisation of neps by size and type …
All
neps present in the raw material and at different process
stages do not show up as undesirable defects in the yarn and
fabric. Depending on the count of yarn, there exists a critical
nep size range which affects the final yarn and fabric appearance.
It is therefore important to identify neps based on its size
and maintain control on the appropriate size of neps. Categorisation
of neps into seed coat and fibre neps is helpful to focus
corrective action to reduce neps. For instance, a higher proportion
of seed coat neps might warrant an increased removal through
extracting more flat strips. On the other hand, a higher proportion
of fibre neps would require corrective action through a closer
setting of card components.
Automatic
sliver preparation for length measurement…
After
nep measurement, the tested material is automatically converted
into sliver form which can then be easily transported to the
feed device for length measurement.
Measurement

Short
Fibre Content (SFC) is used for taking several process
control decisions as well as in raw material purchase.

Premier
aQura measures SFC and other fibre length characteristics
from an end-aligned sample most suited for actual length
measures reflecting the true distribution of the length
of the fibres. The reference length for determining
the short fibres can be configured by the user.
