It is reported that the new nano waterproof fabric is made of polyester fiber coated with millions of tiny silicon filaments, which is the most waterproof fabric manufactured so far. The secret of this super waterproof fabric is coated with a layer of silicon nanowires. This kind of nano waterproof fabric can be advanced chemical waterproof material.
This nano-waterproof fabric with a needle-shaped silicon filament with a diameter of 40 nanometers increases the waterproof effect of the fabric, and the resulting coating prevents rain from penetrating the coating and permeates into the underlying polyester fibers. Sig explained: “The combination of water-repellent surface chemistry and nanostructured coatings can create super-waterproof effects.†Scientists said that the combination of similar waterproof materials and tiny nanostructures is the cause of many super-waterproof materials in the natural world. Such as lotus leaf super waterproof effect. The silicon filaments also form a permanent layer of air between them, similar to this layer structure is breastplate, used by some insects and spiders for underwater breathing.
Sig said that this air layer ensures that the water will never come in contact with the polyester fiber. Even after being immersed in water for up to two months, this nano waterproof fabric remains dry. In addition, according to Sigger's preliminary experiments, when the breastplate moves from the water, it can reduce resistance up to 20%. He said: "This leads to nano-waterproof fabrics that are very suitable for athlete's swimwear." Therefore, swimwear in the future may never be wet. This new coating can be made at a time.
In this coating, the silicon in the gas is concentrated onto the fabric surface, forming nanowires. This coating can also be applied to other textiles, including wool fabrics, chemical fiber fabrics and cotton fabrics, but polyester fibers are best used.
The experiment also shows that this new coating is durable. Unlike some water-repellent coatings, when the nano waterproof fabric is heavily worn, the new coating is somewhat degraded, but the waterproof effect can be maintained without much influence.
