Nanomaterial based coating for future textiles

YarnsandFibers News Bureau 2020-05-29 12:34:47 – Australia

Fabric using nanoparticles that they say could replace present clothing textiles. Characteristics include improved thermal comfort, reducing body temperature from 4.5°C, protecting harmful UV rays, and improving washing durability.

Population growth and improved living standards demand solutions for Cloths with brand new functions to meet changing demands," the investigators state. "Imagine having clothing that can keep us cooler on those sweltering hot days and has the ability to reduce UV radiation from damaging our skin"

The researchers also have developed a nanomaterial-based coating for Fabric that could replace conventional clothing material and pioneer the future of textile development across the world.

Particle Technology, and Monash University's Department of Chemical Engineering, the research team created thin nanoparticle films employing cesium-doped tungsten oxide (CsxWO3) effective at shielding near-infrared rays.

Once employed or incorporated into cotton fibres, the CsxWO3 Nanoparticles have been found to be thermally efficient, reducing body temperature by 4.5°C, attaining a higher assortment of UV protection, also preventing dangerous dermatological diseases, Monash states. The fabric was also capable to keep color quality and durability across numerous wash cycles.

Researchers say there is potential for all these nanoparticles to be used In other fabrics, such as household drapes or outdoor tents and shelters, to insulate houses and reduce UV exposure when outdoors.

Findings from this study were published recently in the journals Applied Surface Science and the International Journal of Chemical Engineering and Applications.

"The main functions of the standard cloths were to maintain the human body dry and warm in cold climates, and to protect it from the warmth and sun in warm climates," Ms. Peng, a Ph.D. candidate and lead author of the project, stated.

"Constant growth in the world's population and improvements in Living standards have required textiles with brand new purposes to meet those changing requirements.

"This study highlights the Excellent potential CsxWO3 nanoparticles possess In diminishing thermal transfer from the clothes item to the epidermis, while maximizing comfort on warm days."

Researchers analyzed the color characteristics, the shielding capacity of near-infrared beams and surface temperature under solar power of these coated cotton materials.

In addition, colorfastness to washing was employed to evaluate the adhesive strength of CsxWO3 nanosheets on the cotton cloth. The nanosheets didn't negatively influence the color or longevity of the cotton cloth.

"Our study provides a very promising step for the production of long-lasting and affordable UV-repellent textiles that can withstand some of the harshest weather and protect the entire body from cancer-causing rays," Ms. Peng stated.

The research team will conduct further studies using CsxWO3 Nanoparticles this season to additional progress the development of new, protective clothing fabric.

The research team comprises: Associate Professor Xuchuan Jiang and Professor Aibing Yu (Monash University), Dr. Bin Su (Huazhong University University)), and others including Ms. Linghui Peng (Ph.D. candidate, Monash University).
