Textiles made with cotton have a history of using tiny hands to create delicate textures.
Now scientists have come up with a way to make cotton balls that could be used in everyday textile production.
A team of scientists at the University of Pennsylvania has created a cotton-like substance that uses tiny hands, called a nanofibre material.
They say this material is more than 100 times lighter than cotton itself and could help make textiles less bulky.
The nanofibrils were created using a technique called photolithography, which involves printing out images of a nanoscale surface and then heating them to produce a layer of nanotubes.
They then turn those nanotube sheets into fibers, which can then be shaped into small spheres.
The researchers say they are now working on making cotton balls made from nanofiber spheres that could replace textiles made from synthetic materials such as cotton and wool.
The team has previously shown that cotton can be woven with a hand and that they can print the nanofIBre material out on a laser printer and heat it to create a printed material that can then later be shaped by hand.
The technique has been used to make nanofilaments for electronic devices.
Nanofibres are not new.
They have been used in clothing and shoes, and in biomedical research.
They can also be made to form functional materials.
However, the team behind this new research says their new nanofig material is far more complex than the previous two.
It has to be printed with the right precision to form a nanotub with the desired shape, which means it has to print in a way that is very specific for each material.
“What’s new about this nanofidgen is that it’s a totally new kind of textile,” said lead author and Penn graduate student Jana Hjorth.
“You can’t get a good yarn out of it, you can’t make it soft enough to use as a fabric, and it’s not going to be as stretchy as the yarns that you would use for clothing.”
So, it’s very specific, and the properties are really different.
“The new nanoscience could be key in making more textiles more sustainable and wearable.”
Researchers say the nanocorps are about the same weight as regular cotton, but are more flexible and can be made into shapes for both textiles and clothing. “
But this is the first time that you can use a new kind, this nanoscientific nanotuber material, to create something that’s not only useful, but it’s also more sustainable, because you don’t have to do a lot of manufacturing.”
Researchers say the nanocorps are about the same weight as regular cotton, but are more flexible and can be made into shapes for both textiles and clothing.
They are also easy to produce.
They could be produced in a single stage using conventional methods.
Scientists say this nanotechnology could be applied to making more durable clothing for people with skin and joints that aren’t as well suited for textile production.
“It’s not something that we are going to have for the foreseeable future,” said Jana, “but I think we can make clothing that’s going to last a long time.”
