This paper is focused on a study of treatment of polyester fabric by an atmospheric dielectric barrier discharge
(DBD). The experiment has been done in air pumping regime. Modification efficiency was analyzed by a drop test
measurement. A time dependent modification was observed. The positive effect of the plasma treatment is more
prominent in the case of 360 s modification time. Stability of modification effect in time is also discussed.

1. INTRODUCTION
Polyester fabric has become one of the most popular
available fabrics nowadays since it meets high comfort
and aesthetic standards of modern consumer. However,
these synthetic fibers have essential lacks: low wettability
and low adhesion. These shortcomings could be
overcome by plasma treatment that has already given
positive results in finishing of synthetic fibers, wool,
linen, cotton and hemp fabric [1-5].
Costs of the textile improvement by means of the low
pressure plasma are governed by purchase of necessary
equipment, technical gases etc. Operation at atmospheric
pressure with implementation of DBD is more profitable
in comparison with the low-pressure treatment, especially
due to its simplicity and low operation costs.
Atmospheric pressure DBD has been used to control
surface wettability and dyeability, and to improve
capillarity of synthetic fabrics. Polyester fabric is a
system with micro and macro-pores. Plasma consists of
various active particles (e.g. electrons, radicals, ions,
photons etc.). These species can attach or react with
polyester (PES) surfaces, changing the nature of the
functional groups present, capillary-porous structure and,
as a result, the properties of the surfaces [6].
The aim of this research is the study of the usability
of the atmospheric DBD for PES fabric modification. In
particular, the effect of the treatment time on surface
wettability was investigated. We considered the
modification effect reduction after some days as
unimportant in practice. The longer modification time
resulted in improved time stability of the treated samples.
2. EXPERIMENTAL
For all the experiments the polyester fabric
(TIS/05/F04/hot 9858) was used as the test specimen.
Prior to DBD treatment the samples were cleaned as
follows:
-double washing in water solution of a proper
washing agent
-rinsing under running tap water
-double washing in distilled water
-chemical cleaning
The PES samples were placed into the DBD reactor
thereafter. The DBD was generated between two plane
iron electrodes, both with diameter 45 mm and 10 mm
thick. The glass barrier was created with an (83x83) mm,
2 mm thick glass table stuck to one of the electrodes.
The DBD assembly was connected to an HV
transformer supplied with 220 V/50 Hz. The DBD input
voltage varied between 18.0 and 18.5x103 V and
discharge current ranged from 1.1 to 1.9x10-3 A.
The series of the experiments were performed in air
under atmospheric pressure (745…753) torr and room
temperature (25…27)°C. The samples were treated for
240 and 360 seconds. The air was pumped through the
reactor at the flow rate of 0.075 m3/s during the
experiments. The permanent pumping provided stable air
composition during the treatment. The results are
compared here with the previous experiments [7].
The wettability was evaluated by means of the drop
test [8]. Water solution of potassium dichromate
(5 x 10 3 g/μl) was used as a test liquid for better
visualization. The 20 μl of the solution was dropped on
the textile sample and the feathering spot size was
recorded with a camera. Monitoring was performed in 5
seconds intervals within the first 30 seconds after drop
incidence on the fabrics and in 10 seconds intervals
afterwards. The total observation time was 200 seconds.
The area of the spot in the 60th second after the drop
release was used as the standard for the evaluation.
3. RESULTS AND DISCUSSION
The samples of polyester fabric were investigated in
unmodified state and with 240s and 360s modification
time with pumping.
The improved wettability was observed for the fabric
treated at longer time. At longer modification time the
frequent undesirable sparks appeared between two
electrodes, presumably because of the high concentration
of active plasma particles generated in the plasma
volume. Air pumping out from the reactor was applied to
avoid an ignition of samples from micro discharges.
Plasma radicals penetrated through the fabric fibrous
micro- structure between two discharge electrodes and
modified the surface of the material. Processing by
Problems of Atomic Science and Technology. 2006, № 6. Series: Plasma Physics (12), p. 195-197 195
plasma active particles influenced the capillary-porous
structure of the fabric altering its macro- and micro pores.
Activated in plasma oxygen and nitrogen species reacts
with organic constituents of polyester chains to form
polar groups on the surface and hence the fabric
wettability increases.
Fig.1 represents the time dependence of the
feathering area with modification time of 240 seconds.
The wettability improvement is most remarkable
immediately after the treatment. On the 3rd day after the
treatment the area of feathering decreases but still it
exceeds by 50 % that of the unmodified sample. On the
13th day only an insignificant effect can be discerned.
And on the 20th day there is no difference between
modified and unmodified sample.
Fig.2 shows the time dependence of the fabric
feathering area for the longer modification time – 360
seconds. More stable preservation of the modification
effect is evident in this case. In 17 days the speed of drop
spreading was reduced only to 600 mm2. In the 20th day
the state of the samples with 360-seconds modification
time approached the unmodified state.

CONCLUSIONS
Atmospheric DBD was employed for the treatment of
the PES textile samples. The modification periods were
for 240 and 360 seconds. The air in the reactor was
pumped during all experiments.
The most stable modification was achieved with the
modification time of 360s. The stable of modification
effect was observed in 17 days after the treatment.
