Model: PFL - Polymerizing Machine

A large quantity of cotton fabrics is printed with pigments. It is a relatively
simple printing process which doesn’t requires steam fixation and wash off..

The pigment fixation on the fabric is achieved with the polymerization of the
binding elements in hot air at 150°C.

Arioli PFL polymerizing machine is a special plant with a free loop
transportation, designed to achieve a tensionless fixation of fabrics and
jersey.

PFL is used for:

- curing of pigments on cotton or polyester

- curing of resins

- curing of flame retardants.

The machine is composed by a steel structure with highly insulating rockwool
panels. The system is designed to avoid heat transmission towards a good
insulating performance.

Ventilation is obtained through centrifugal fans with a recirculation power
of 24000 m3/h of air per section. Air is distributed through shaped ducts in
order to collect and drive all the possible oil or fuel condensation being
developed in the segments to the outside ambient.

The fabric transportation is by free loop, to store up to 350 meters of
fabric in the machine, and dispose of a relatively long polymerization time with
a perfect colouring fixation, no yellowing effects, no fabric harshing and low
energy consumption.

Special de-ionization bars are installed at the chamber inlet and/or outlet
to reduce static electricity being developed on the fabric cloth.

Air heating may be obtained with steam or thermo oil batteries. Also the use
of direct gas burners is foreseen.

Special exhausting fans drive air out constantly from the inside of the
chamber, thus avoiding a humidity or gas saturation which may cause explosive
mixtures.

It is possible to fit special steam injectors in the entry area, for special
finishing effects.
