New upgrade transforms the ACW into
Recently, upgrades and retrofits were made
available for Oerlikon Barmag ACW-series winders, with which the
benefits of the WINGS concept become tangibly close for
operators of POY spinning systems equipped with ACW technology.
Worldwide, thousands of winders could take advantage of this
In addition to savings in terms of
energy, waste and HR, the benefits of the WINGS concept above
all include the consistently high yarn quality, making WINGS
yarn a winner in further processing. Particularly with regards
to its dyeing properties, the yarn is considerably superior to
products manufactured using conventional winder technology.
Yarn producers can now also achieve these
typical WINGS properties with ACW winders – with a corresponding
system upgrade. The ACW WINGS conversion components and ACW
upgrades for draw units can be installed as plug-in units in
virtually no time at all, hence minimizing system downtimes.
Analog to WINGS, the new ACW WINGS draw unit is more compact and
also guides the yarn using rollers instead of yarn guides. This
minimizes friction for the yarn and the angles of deflection
remain the same, which in turn optimizes the yarn tension on all
Already being used in China
The first expansion phase with 96
positions is already successfully operating at Chinese polyester
yarn manufacturer Zhejiang Rongsheng. “We achieved excellent
yarn values after just four days. The yarns are of AA quality
for a full package rate of 98% and a yarn break rate of 0.5 per
ton”, summarizes Xu Yongming, Plant Manager at Rongsheng,
talking about the upgrade package. “This has allowed us to once
again become one of the top manufacturers with our ACW yarns.” A
second expansion phase with 88 further positions will follow at
the end of 2019.
The conversion package is also
particularly interesting as a result of its fast ROI
(return-on-investment) of less than one year. ACW WINGS is
available for all ACW-type POY / HOY winders for polyester,
polyamide 6 and polyamide 6.6.
