Abstract- The antibacterial properties of Ag and Ti+O implanted hospital textiles were compared to the ones which were treated with Nano
Particle based liquid solutions.
Ion beam implanted textiles were produced at HCEI (High
Current Electric Institute) in Tomsk,Russia in cooperation
with Ege University Surface Modification Laboratory
(picture1.). Conventionel Nano Textile Technology applied
fabrics were obtained from Belgium and China.
In this work, the antibacterial properties of Ag and Ti+O
implanted hospital textiles were compared to the ones which
were treated with Nano Particle based liquid solutions. It was
observed that Conventional Nano Textile Technology based
textiles have better antibacterial properties for %100 Cotton
textiles (Alpaka Cotton).However, ion implanted polyester
textiles (%75 Polyester-%25 Cotton mixed fabric) have better
antibacterial properties than the ones treated with Nano
Particle based liquid solutions.The reason for this could be
that the polyester textiles have structures suitable for ion
implantion where as 100% cotton textiles have structures
suitable for Nano Particle based liquid solutions (picture.2(a)
and (b)). It was observed that, the surface treated cotton and
polyester hospital textiles can sustain antibacterial properties
after 30 washes and also found that Silver (Ag) and Titanium
Dioxide (TiOR2R) have equal antibacterial properties.
Test Bacteria; Staphylococcus aureus, ATCC 6538 (Gram
positive organism) was used as a test bacteria. Test bacteria
make a fresh transplant from stock culture before the
experiments.
To evaluate the antibacterial activity of the ion-implanted
and Nano Textile based textiles, an American National
Standard (ATCC Test Method 100-1993) [1] was used. All the
samples were washed 30 times with detergent at 49C in
shaking condition according to the AATCC 124 Test method
[2]. Experiment repeated for the washed samples to detect the
effect of the washing of the antibacterial activity.
Bacterial colonies were counted as bacteria per sample.
Antibacterial Efficiency Reduction is calculated by the
formula;
R=100x[(B-A)/B]
R= (%) Antibacterial Efficiency Reduction
B= Bacterial Colonies accounted from Petri dishes belongs to
untreated swatches just after from the inoculation
(Result of Contact time detection; T0)
A= Bacterial colonies accounted from Petri dishes belongs to
treated swatches (Ion Implantation or Nano Textile
Technologies)
24 hours later from the inoculation
To evaluate the antibacterial activity of the ion-implanted and
Nano Textile based textiles, an American National Standard
(ATCC Test Method 100-1993) [1] was used.
Test Bacteria; Staphylococcus aureus, ATCC 6538 (Gram
positive organism) was used as a test bacteria. Test bacteria
make a fresh transplant from stock culture before the
experiments.
Culture Medium; All experiments were implemented using
nutrient broth/agar medium consisting; peptone 5 gr, beef
extract 3 gr, distilled water 1 L.
This work may pioneer the study of antibacterial and some
other effects of ion implantation on textiles.
