1. Plasma is a versatile technology to chemically and physically modify the surface

of materials.

2. Plasma technology is used to achieve new or improved properties to textiles. It

is an alternative environmentally friendly technology to complement or

substitute several conventional textile processes.

3. Research and development of plasma treatments applied to textiles are still

globally increasing. Different studies have been done on natural, artificial and

synthetic fibers.

4. Sputtering, etching, chemical functionalization, free-radicals generation and UV

radiation are some of the most important effects conferred by plasma treatments

to textiles.

5. PECVD, PVD and superficial grafting are plasma processes which involves the

formation of nanometric layers.

6. Plasma treatments are increasing their presence in the textile industry for

several applications.
