types and material and covers the
complete yarn count range with only
one sensing head.
Even fancy yarns are cleared effi-
ciently and without compromise us-
ing simple clearer settings. Thanks
to optimized yarn path of the Zenit
sensing head, there are very few
abrasive effects on the yarn even
when the winding speed is high. The
7-segment display which is built
into the sensing head informs of oc-
currences already at the spindle.
So far, the YarnMaster Zenit F
has ensured foreign matter clear-
ing with high precision. The latest
developments have been integrated
in software and hardware develop-
ment and have again significantly
improved clearing efficiency.
Polypropylene recognition
Yarn contamination by white or
transparent polypropylene fibres
causes production and quality losses.
White PP only becomes visible after
dyeing or bleaching. Clearing im-
proves the yarn quality considerably
and prevents complaints concerning
the dyed end product. PP
and other synthetic foreign
matter that is transparent or
identical in color with cot-
ton can hardly be recognized
with conventional clearing.
To overcome these prob-
lems, Loepfe has upgraded
to the latest technology and
developed the proven P sen-
sor to the P2 sensor. Cotton
yarns as well as blends are
thus efficiently cleared.
The efficient and reliable new P2
sensor from Loepfe is customer-ori-
ented and its advantages are:
l
Controlled, reliable clearing of
synthetic foreign matter provides a
decisive competitive advantage and,
in most cases, is mandatory in mod-
ern yarn trading.
l
Complaints because of foreign
matter in the finished, dyed fabric
are reduced.
l
The door to the most demanding
market segment is opened. In this
segment, yarn cleared of polypro-
pylene is a basic pre-
requisite.
l
Better quality of the
end product and thus
better prices
l
Less raw material
waste
l
Better utilization of
resources
l
Increase in effi-
ciency of downstream
processes and cor-
responding cost sav-
ings.
Spinning
mills
processing their yarns with the
YarnMaster ZENIT FP yarn clearer
are well prepared for the future.
