Nanotechnology clothing controls heat and odor and solves pests

Publicado em 19 março 2019

In the coming summer, textile industries should bring productive cloth to the market, which will maintain low heat, control sweat odor, protect the sun and protect mosquitoes. Edies, Egypt Dengue fever, yellow fever, chikungunya and zico virus vector.

Some garments with this specialty use technologies developed by Nanox – are born in the FAPESP Program of Innovative Research in Small Business (PIPE) and the Center for the Development of Functional Materials (CDMF), in research, innovation and intervention center There is one. (CEPID) funded through FAPESP.

In partnership with the textile industry, the company develops with particles with various properties in the nanometric scale (billion part of the meter). Among them, which causes bad odor to control microorganisms, reflects the electromagnetic radiation of the Sun and is regulated in repulsed and pesticides regulated.

"We are already running some projects with cloth industries in the final phase of the development of textiles with these properties," Nanoco co-founders and operations director Daniel Minozzi told Agnesia Fapepun.

The particles developed by the company are composed of various inorganic materials and can be added to the cloth together or in combination to provide the desired efficiency. Which controls the odor, for example, is based on silver, zinc and copper and has bacteriocirus, antimicrobial and self-stabilizing properties.

When inserted into tissue fibers, these nanoparticles protect against the development of bacteria, fungi and bacteria which cause bad odor and prevent yellowing, promise the company.

"The advantage of these antimicrobial nanoparticles is compared to other chemicals contained in the anti-odor cloth on the market, it is more resistant to washing, temperature and friction," said Minozzi.

Furthermore, they have little environmental impact and are not allergic. Therefore, they can be used in any kind of fabric that comes in direct contact with the skin, such as ordinary clothes, sports, intimate beds and baths and professional uniforms. "

The nanoparticles for protecting the sun and providing more thermal comfort can be applied to the general clothing, sports and beachwear, as well as the curtains and uniforms of professionals, which need to come out of the sun for long periods of time.

The nanoparticles have polo glass microscopiers that are covered by thin films and Zinc is transparent to oxide, aluminum or titanium. These nanostructured materials act as microscopiers and can infiltrate the tissues that reflect infrared and ultraviolet rays. In this way, they can reduce the thermal transmission (heat transfer) to the fabric by 65% ??to a wavelength of 500 to 4,000 nanometers.

The technology was developed by a project supported by the Pipe-Phapespe.

In tests carried out by the company, when the sun exposed to the rays, the fabric particles containing the particles represent a reduction of up to 6.5 ºC compared to the same fabric without particles.

"Today's texture protects against the sun protects against ultraviolet rays, we are able to reflect the inferred radiation of the developed nanoparticles. In this way, they make it possible to reduce the heat of the fabric and to use it during the day," Minozzi said. "It's quite innovative technology."

Nanopartical technology is an innovative innovation to protect against flying and crawling insects, he said.

The company does not disclose the details of technology for industrial secrecy reasons but says that innovation is in the system of disinfectant disinfectant nuclear or pesticides in the nanoparticles and fix them in tissues.

"Some major problems of replenishing the cloth on fabrics are the determination of the product's odor and washing process. We have developed a system that can contain pesticides in a pesticide or tissue," he said.

Nanoparticles with a company-developed antiviral, antimicrobial and auto-sterizing properties are applied in a range of products today. There are PVC films on the surface of medical and dental instruments, such as plastic utensils and PVC films, packaging food, sanitary seats, shoe insulas, hairdryers and hairpins, paint, resin and ceramics and tweezers, drills, and skulls.

Today the company's largest markets include white goods appliances such as refrigerators, water fountains and air conditioners, carpets and rugs.

"Since we have been working in this segment of the carpet for eight years, our most effective entry path in the textile segment is," Minozzi said.

The company currently exports to local countries such as Mexico, Colombia, Chile, Italy, China and Japan and recently opened a subsidiary in Boston in the United States.

"The idea of ??a branch office in the US is to simplify and accelerate licensing for the commercialization of our product in the US market, which is in the final evaluation stage for the relief," Minozzi said.
