How can nanotechnology be used to make fabrics waterproof?

How can nanotechnology be used to make fabrics waterproof?

Nanoparticles of silica incorporated into the weave of a fabric or sprayed onto its surface create a coating that repels water and stain-producing liquids. The angle and roughness of the silica coating creates enough surface tension to ensure that liquids form beads that roll off the fabric rather than soaking into it.

How is nanotechnology used in fashion clothes?

The most common nanomaterials in clothing are nanosilver and nano-titanium dioxide. Nanosilver is woven into fabric to give it anti-bacterial properties, fending off the bacteria that make those clothes smell after you sweat. Nano-titanium dioxide adds sun protection to clothing just as it does in sunscreen.

Is nanotechnology waterproof?

Nanotechnology has made it possible to waterproof almost any material. The nano coating provides a second, water- and dirt-repellant skin. It can also provide protection from corrosion, scratches and graffiti.

What is nanotechnology fabric?

Nanotechnology fabrics are textiles manufactured to have special qualities like hydrophobicity and high durability. Nanotechnology fabrics are a relatively new and expanding field. They have applications in bioengineering, electrical engineering and computer science.

What are the disadvantages of using nanoparticles in fabrics?

However, recent studies have shown that nanosilver will pose a great risk to the environment as it is increasingly used in clothing. Silver nanoparticles in clothes can cause an increase in the concentration of silver ions in waste water, the sludge from which can end up in agricultural lands as fertilizer.

What is nanotechnology in cosmetics?

Nanotechnology incorporation in cosmetic formulation is considered as the hottest and emerging technology available. Cosmetic manufacturers use nanoscale size ingredients to provide better UV protection, deeper skin penetration, long-lasting effects, increased color, finish quality, and many more.

What are some advantages of nanotechnology in cosmetic products?

Nanotechnologies allow enhanced properties in many areas of interest to the cosmetics industry, including UV protection, deeper skin penetration, and improved hydration. Nanotechnology also allows the “packaging” of many ingredients in semi-soluble packets that breakdown as the product is being applied, not before.

Is ceramic coating waterproof?

Ceramic coating is water-resistant, but not fully waterproof.

What is waterproof coating?

What are waterproof coatings? Waterproof coatings cover the masonry of your building with a waterproof substance, stopping water from getting inside and wrecking havoc. The coating can be part of the masonry itself, a liquid coating (such as a spray or paint) or an additional sheet covering.

How do you think nanotechnology treated fabric works?

The fibres (called “nanowhiskers”) are waterproof and increase the density of the fabric. This increases the surface tension on the outer layer of the fabric so liquid cannot soak through.

Is there any toxicity of using nano products?

Out of three human studies, only one showed a passage of inhaled nanoparticles into the bloodstream. Materials which by themselves are not very harmful could be toxic if they are inhaled in the form of nanoparticles. The effects of inhaled nanoparticles in the body may include lung inflammation and heart problems.

What products contain nano materials?


  • Physical sunscreens.
  • Make-ups (e.g blush, foundation, mascaras)
  • Toothpaste.
  • Face creams (anti-aging, eye cream)
  • Baby care products (e.g diaper cream)
  • How is nanotechnology used in waterproofing?

    Waterproofing with Nanotechnology. The principle behind the fabric’s water resistance is that the 40-nm wide silicone nanofilaments are extremely hydrophobic in nature. Moreover, their spiky structure enhances this surface chemistry and forms a protective coating on the fabric to prevent water droplets from entering or soaking the cloth.

    What are nanotechnology clothes made of?

    At the moment, clothes featuring nanotechnology are largely made from standard fabrics upon which a nano-coating has been applied. But in the future we’re likely to see more fabrics made from nanofibres, with nanoparticles and nanofilaments an integral part of the weave.

    What is nanopro coating on rain jackets?

    Rain jackets, rain pants, and other gear with our proprietary NanoPro coating technology ensure you’re prepped for soaking commutes, damp hikes, and stormy treks around town.

    How do nanoparticles keep clothes soft and wearable?

    The particles’ tiny size means the garment stays soft and wearable. Nanoparticles of silica incorporated into the weave of a fabric or sprayed onto its surface create a coating that repels water and stain-producing liquids.
