Now a days, Researchers have designed a thermal regulation textile.It has a 55% greater cooling effect than cotton. It translates to cooler skin temperatures when wearing clothes made of the new fabric. This material can fabricated using 3D printing and could provide a simple, low-cost way to cool the human body . It reduce the need for air conditioning on hot days.

Liangbing Hu at the University of Maryland, have published a paper on the new thermal regulation textile in a recent issue of ACS Nano.

“This is the first time. This highly thermally conductive textile is 3D-printed with excellent mechanical strength. It greatly enhanced thermal conductivity, which can cool the body significantly, especially for office settings for energy savings,”

This textile is made of a nanofiber composite consisting of boron nitride and poly(vinyl alcohol), or PVA. It using 3D printing, the researchers fabricated nanofibers . It’s highly aligned, uniform, and densely packed together and demonstrated .This woven nanofibers fabric exhibits a strong cooling effect .

A key property of the next textile is its high thermal conductivity.It allows body heat to pass through the fabric by conduction to the ambient environment. In contrast, most conventional textile fibers such as cotton typically have a lower thermal conductivity. It can traps more of a person’s body heat inside their clothing.

In simulations, the researchers showed that nanofibers fabric has a more thermal conductivity. It’s thermal conductivity is more than twice as high as cotton fabrics. 1.5 times higher than PVA fabric without boron nitride nanofibers.

Several other types of thermal regulation textiles have recently been developed for maintaining a cool “microclimate” near the human body.

For instance, moisture-wicking fabrics cool the body by removing excess moisture, but primarily work only in highly humid (or sweaty) circumstances. Some technologies use cold packs and others consume large amounts of energy. The researchers in the new study expect that the simple, low-cost nanofiber textile demonstrated here may offer one of the most practical solutions for keeping cool in hot weather.

In the future, the researchers plan to realizing these applications.

“We are carrying out more research to further improve the performance through materials design and also working on scalable demonstrations using 3D printing,” Hu said.
