This document discusses the use of nanotechnology in textile finishing and innovation. It outlines several textile applications of nano technology including making materials water repellent, providing UV absorption and protection, improving durability and abrasion resistance, adding fire retardancy, enabling anti-microbial properties, and allowing controlled release of additives. The document also discusses using plasma treatment and microencapsulation technology to functionalize textiles by making them hydrophobic, antibacterial, or able to release fragrances over time.

- 4. •Irving Langmuir first used the term plasma in 1926 to describe the inner region of an electrical discharge •Plasma treatment has an explosive increase in interest and use in industrial Applications as for example in medical, biomedical, automobile, electronics, semiconductor and textile industry • Plasma, as a very reactive material, can be used to modify the surface of a certain substrate (typically known as plasma activation or plasma modification), depositing chemical materials (plasma polymerisation or plasma grafting) to impart some desired properties, removing substances (plasma cleaning or plasma etching), which were previously deposited on the substrate

- 7. The specific surface area of cotton after oxygen plasma treatment is increased. On the other hand, the treatment with hexamethyldisiloxane (HMDSO) plasma leads to a smooth surface with increased contact angle of water up to a maximum of 130°. Thus, a strong effect of Hydrophobisation is achieved. Similarly, when hexafluoroethane plasma is used instead of HMDSO plasma the surface composition of the fibers clearly indicates the presence of fluorine and the material becomes highly hydrophobic. The antibacterial properties of polyester fabric after activating its surface by atmospheric pressure plasma and then grafting it with chitosan oligomers/polymers.
