The features of nanotechnology have helped not only textile scientists, but also the textile business in a big way. The Nano Finish concept has given birth to many new applications and exceptional textile finishes.
Originally - the word nano came from the Greek word "nanos" which means "dwarf" or "dwarf". An object can be compared to the fineness of a nanoparticle that is 1,000,000 times smaller than the diameter of a human hair. One meter is one billion nanometers, so nano-finishes can be used in textile fabrics for various functional properties of nanomaterials.
The application of nanotechnology in the textile industry facilitates the creation of smart textiles due to the different functional properties of textile materials.
Currently various nano finishes are available and they are as follows: -
1. UV protective finish
Nanoparticles used for the development of UV protective finishes, which have temperature, chemical and electrical resistance capabilities, can block ultraviolet rays. Particles are composed of clay nano flakes, which are composed of hydraulic aluminio oscillations that contain various chemical compounds and crystal structures. In addition, zinc oxide, like this metal oxide, is used for UV protective finishes.
Bonded clothing by these nanoparticles can protect people from harmful UV rays and protect the skin from potential damage. Moreover, the textile industry has a finish that provides UV protection with SPF (Sun Protection Factor).
3. Anti-bacterial finish
This anti-bacterial nano finish is designed to keep clothes and clothes clean from bacteria and fungus. Titanium dioxide, zinc oxide and silver particles are used for this finish. Metal ions and complexes have anti-microbial effect power quality.
The surface area of silver particles is so large that it can cover the whole fabric. When bacteria or fungus comes in contact with silver coating, it inhibits the growth of bacterial and fungal cells. Silver has many medical properties that can work to prevent infections, odors, itching and wound growth. Silver encapsulated dressing is used to make health hygienic items that heal wounds, burns.
4. Other-fighting finish
This type of finish is commonly used in performance clothing, socks, body underwear and sportswear. Tourmaline is used to develop other repellent finishes, which produce negative ions when exposed to oxygen, carbon dioxide and water molecules in the air. These ions create a magnetic field that inhibits bacterial growth. If there are bacteria, the stench increases. This nano finish can remove 99% bacteria, 90% bad smell and 75% moisture.
5. Anti-wrinkle finish
Resins were commonly used in fabrics to achieve anti-crease properties, which reduced fiber and fabric strength, low friction, low durability, and reduced respiratory capacity. Nano silica and nano titanium dioxide particles are used to develop anti-wrinkle finishes of cotton and silk fabrics. This Finnish garment protects garments and fabric from creases for a long time.
. Flame Retardant Finish:
Nano antimony pent oxide is a textile material commonly used to finish flame retardants. Used to make halogenated fine particle anti-flame finish on textile material.
. Anti-static finish
Man-made synthetic fibers, such as polyester and polyamide, have static charge problems. This anti-static finishing is done with nano antimony doped tin oxide, zinc oxide and titanium dioxide for its electronic conductive nature and good electrical conductivity. The nanoparticles are properly attached to the fibril to create an electrically conductive network that prevents the formation of isolated chargeable area, voltage peak.
In addition to this nano finish this material is currently being used in the textile industry in a self cleaning and hydrophobic nano coating. The reason for the popularity of nano coating is that the protective layers used are not visible to the naked eye. This finishing technology is environmentally friendly and non-toxic. Clothing with nano finish is much brighter and more durable than regular clothing.
Extra-ordinary finish development for all types of fibers now has less and less potential in the field of nanotechnology. However, this type of finishing is a major obstacle to the high cost and time consuming textile industry. Currently the United States, Japan and Europe are at the forefront of nanotechnology. With further research and development, nanotechnology can be used to create smart textiles with multi-functional chemicals. More
