Fadis SpA: Elastic yarn winding machines
Fadis offers high-end
machines to process elastic yarns, both in packages as well as
in hanks form. In 2003, Fadis launched an important
technological innovation, the FAPP™ (Fadis Precision Package), a
new technology which is able to satisfy most precise
requirements of elasticized yarn dyeing.
In 2007 Fadis has presented an innovative machine for elastic
yarns, the SINCRO M, a new concept of winding with precision
crossing and electronic yarn guide system, that can reach speeds
up to 1750 m/min.
With the SINCRO M machine, it is possible to produce FAPP™
low-density packages (FAdis Precision Package), which allows for
wide retraction margins of the yarn during the dyeing phase,
thus keeping a high residual elasticity percentage of the
Therefore, with this widely tested technological system, and
the possibility of unwinding the FAPP™ with the SINCRO RFM SW
rewinding machine with its tension controlled motorised
unwinding system, it is now possible to obtain qualitative
results quite similar to Hank dyeing, but with the same
simplicity and economy typical of yarn package dyeing.
The main features are presented here
for the interest of our readers.
The fundamental innovation of this machine is the use of the
precision crossing with electronic yarn guide and positively
driven swift instead of a positively driven bobbin.
With the precision crossing with positively driven swift
technology, it is possible to obtain FAPP™ with a perfect and
controlled yarn laying, without patterning, which is a guarantee
for their excellent unwinding at a constant tension, thus
allowing to keep elasticity and a high performance during
subsequent production phases.
With the positively driven swift with the adjustable
circumference. It is possible to optimize FAPP™ formation
according to the elastic characteristics of each single yarn. As
each yarn has its own elasticity and its own retraction
coefficient during the dye process, this additional features
benefits the customer.
It is important to note that due to the possibility of
adjusting the swift for every single article, the parameters may
be optimized in such a way that various types of yarns have the
perfect retraction margin during the dyeing phase, thus ensuring
a high percentage of residual elasticity of the elasticized yarn
Thanks to this highly evolved technology, it is possible to
process not only stretch polyamide yarns, but also all those
elasticized yarns whose main prerogative is to maintain a high
degree of residual elasticity after dyeing, such as Corespun
yarns, covered elastomeric yarns, elasticized viscose, nylon PBT,
polyester T400 and other similar yarns.
According to the diameter of the chosen swift, the produced
FAPP™ may then be dyed either in a basket or in the column.
The machine can be equipped with a large diameter feed roller
with a programmable speed for yarn overfeed (up to +70%).
Last but not least the machine can be equipped with an
intermingling jet to intermingle 1 ply yarn to then reduce the
problems of filament breakages/ separation during dyeing process
or to intermingle 2 ply yarn.
