Nanotechnology:
Nanotechnology is a field of research and innovation concerned with building ‘things’ – generally, materials and devices – on the scale of atoms and molecules. Nanotechnology is defined as the study and use of structures between 1 nanometer and 100 nanometers in size.
Let us see here 5 Latest Nanotechnology inventions in Textile Industries.
1.Novel sensors could enable smarter Textiles:
A team of engineers at the University of Delaware is developing next-generation smart textiles by creating flexible carbon nanotube composite coatings on a wide range of fibers, including cotton, nylon and wool. Fabric coated with this sensing technology could be used in future “smart garments” where the sensors are slipped into the soles of shoes or stitched into clothing for detecting human motion.
2.No more washing, nano-enhanced textiles clean themselves with light:
Researchers from RMIT University in Melbourne have developed a cheap and efficient new way to infuse textiles with tiny strands of silver – which can degrade organic matter when exposed to light. This work paves the way towards nano-enhanced textiles that can spontaneously clean themselves of stains and grime simply by being put under a light bulb or worn out in the sun. i-e It can bring self-cleaning cloths which can clean themselves without requiring water or washing machine.
3.Fabric will automatically Cool or Warm You as needed:
Researcher from University of Maryland have created a Fabric that can automatically regulate the heat passage so that it can keep the wearer at comfortable temperature at all times irrespective of whether the surrounding is Cool or Hot.
The Researchers constructed an infrared-adaptive textile composed of polymer fibers coated with carbon nanotubes. The yarn itself expanded and collapsed based on heat and humidity, which changed the spacing of the fibers. Wider fiber spacing allowed the textile to breathe but also altered the infrared emissivity of the textile. This allowed for better heat exchange under hot and wet conditions. The self-adjusting emissivity of the textile could help toward wearable thermal-management attire.
4.Washable Smart Fabrics with LEDs:
Researchers at MIT have now embedded high speed optoelectronic semiconductor devices, including light-emitting diodes (LEDs) and diode photodetectors, within fibers that were then woven at Inman Mills, in South Carolina, into soft, washable fabrics and made into communication systems.
Beyond communications, the fibers could potentially have significant applications in the biomedical field, the researchers say. For example, devices using such fibers might be used to make a wristband that could measure pulse or blood oxygen levels, or be woven into a bandage to continuously monitor the healing process.
5.New coatings make natural fabrics waterproof:
Fabrics that resist water are essential for everything from rainwear to military tents, but conventional water-repellent coatings have been shown to persist in the environment and accumulate in our bodies, and so are likely to be phased out for safety reasons. That leaves a big gap to be filled if researchers can find safe substitutes.
Now, a team at MIT has come up with a promising solution: a coating that not only adds water-repellency to natural fabrics such as cotton and silk, but is also more effective than the existing coatings.
