Uster Technologies Ltd. has
launched a new CLASSIMAT
classification system. The USTER
CLASSIMAT 5 takes quality as-
surance to a new level, enabling a
deeper understanding of defects and
their causes, and finding ways to
prevent them. Innovative features
and capabilities can pinpoint out-
liers, providing consistent quality
levels for both producers and users
of yarns.
Parameters measured by the
USTER CLASSIMAT have played
a vital role in spinning mills and
yarn trading worldwide since the
instrument was first developed
more than 40 years ago. The classi-
fication of yarn defects according to
their size and length into 23 stand-
ard classes is used extensively to
certify yarn quality, to help control
spinning processes and to optimize
yarn clearing at the winding stage.
In the meantime, quality demands
have increased enormously. While
fault classification based on the
well-proven analysis of thick and
thin places remains fundamental, it
must now also cover critical param-
eters such as foreign matter, count
variation, periodic faults, uneven-
ness and hairiness. An important
quality management aspect that has
grown rapidly in significance is the
need for consistent quality as much
as absolute quality. This demands
critical new tools for large-scale
production, to assess extreme
deviations from the quality norm,
referred to as outliers.
Classifying all outliers
Addressing these requirements,
USTER CLASSIMAT 5 delivers all
the traditional classification stand-
ards, while broadening its scope to
include outliers, which are often the
root cause of claims and inconsist-
