Nanofibers and their potential in the development of functional clothing
Imagine an asphalt road. On one side you see a hobby jogger, on the other a professional runner. These people have one thing in common - they need clothes that keep them warm, don't get wet, and at the same time get rid of water vapor created by sweating. What options are available to them? And what role do nanofibers play in this?
Sportswear with nanofibres – protection against water, wind and a surprising breathability!
Nanofibres are not just in highly protective respiratory masks. They are fast gaining the prominence in clothing industry, namely for two reasons – the ability to create functional clothing that is breathable, and, at the same time, protects the wearer from the vagaries of the weather.
Imagine an asphalt road. On one side you see a recreational jogger, on the other a serious runner. These people have something in common - they need clothes that keep them warm and waterproof, while getting rid of the water vapour from sweating. What options are open to them?
They will most likely reach for a conventional fabric, which will protect them from water, but will not be breathable, so they will sweat uncomfortably and overheat because the material will not let the excess water vapour and moisture escape. Scientists have therefore immersed themselves in the development of a material that provides 100 % protection and comfort.
The first break was the so-called impermeable film. Although it successfully blocked contaminants and refused to release toxins, it was unfortunately uncomfortably heavy and bulky. In addition, it did not let the accumulated moisture out, so the wearer was completely wet after a few minutes. A similar fate awaited the so-called impermeable polymer foil, which, although it kept the user pleasantly warm in winter, was unbearably hot and humid in summer. The third attempt entailed a microporous non-woven membrane that was lightweight and relatively affordable.
In the end, the best solution turned out to be the implementation of nanofibres. Fibres and membranes produced by electrostatic spinning have shown great potential in the development of functional garments as they provide thermal comfort to the wearer, maintain the breathability of the material and wick away excess moisture.
Nanofiber will upgrade ordinary textiles to a new level and give them specific properties!
NanospiderTM technology is suitable for the production of the most specific nanofibrous materials, namely those that allow the accumulated vapor to pass through the garment without any problems and ensure the wearer's dryness, warmth and protection. The nanofiber made by the NanospiderTM free surface spinning method stands out for its compactness and porosity without the risk of losing its protective properties.
The process of enriching the textile with a nanofiber layer is more than fascinating in itself. A light, porous nanofiber membrane is inserted between two layers of classic fabric, and this entire "sandwich" is subsequently laminated on an engraving roller. It is surprising that inserting a thin nanofiber in the middle between two layers of fabric has almost no effect on breathability and vapor permeability. At the same time, the water resistance of the resulting fabric will improve dramatically.
In addition, tests showed that the presence of a thin layer of nanofibers improves the thermal comfort of the garment compared to a classic additional fabric. The compressed fabric is water and wind resistant, immediately wicks away moisture and has good thermal insulation, protecting the body from the cold.
