Integrated into textiles, nanotechnology transforms these into Nano textiles and significantly improves their quality and functionality. To achieve them, companies create tiny fibers or use prefabricated nanomaterials to incorporate directly into textiles.

Steps to create textiles with nanofibres

The two main steps of innovation are at the time of production of such nanofibres and during the finishing of textiles.

Textile Manufacturing begins with the use or creation of fibers that are transformed into filaments. This step, called spinning, is to pass through a dye, fibers in solution or melt, to obtain filaments. During this process, it is possible to cause chemical reactions, adding nanoparticles as filaments used and some improvements. When finishing (penultimate stage of manufacture), textiles may again be customized by other chemical operations, thermal or mechanical order to improve the qualities of the resulting product.

This is intake of metal nanoparticles during dyeing for strengthening resistance to photochemical aging; reduce the amount of dyes used and their impact on the environment. The nanofibres are obtained by reducing an aqueous chlorinated salt of gold or silver with tannic acid.

However, the suspended nanoparticles tend to agglomerate, which affects the uniformity of the textile. It is then necessary to use an ultrasound system placed at a spray nozzle to separate them.

Another technique is to hang the nanoparticles to the fibers, or by modifying the surface of the nano-object to cling to the fibers, or by grafting a polymer to the nano-object and embedding it in a resin finish. Increasingly successful, this strategy avoids the risk of skin contact.

Finally, the sol-gel is revitalized in textiles. It consists of a deposit, in aqueous or aqueous-alcoholic phase, with a thin layer of optically transparent oxides. Its name refers to the apparent gelation observed during the reaction.

Not only this treatment based on silicon chemistry, has a very good temperature resistance but also it promotes lower drying temperatures and the lack of release of volatile organic compounds (VOCs). You can purchase nanofibers from online vendors depending on your need.
