Waterproof fabrics are familiar to many of us. From diving and playing to emergency rescue, waterproof fabrics can be said to have been applied to all aspects of our lives. However, have you ever thought about how powerful waterproof fabrics are? Recently, scientists from the Lodz University of Technology in Poland announced that they have successfully developed a cold plasma waterproof fabric whose waterproofness has reached the current high level.
Scientists from the Lodz University of Technology in Poland are demonstrating the effect of the new waterproof fabric they developed: a drop of water was not absorbed after being dropped on the fabric, but like a pearl, it moved as the fabric moved. Keep scrolling. Regarding the magical effect produced by this fabric, a professor from Lodz University of Technology introduced us: “The superhydrophobic coating we invented has the property of preventing water from seeping on the surface of the fabric fiber. Therefore, when water droplets drip, it will not Absorbed by the fabric. Although there are many waterproof fabrics on the market, none are as waterproof and durable as the fabric we invented. ”
The waterproof fabrics on the market today are all based on the so-called lotus effect principle to achieve waterproof purposes. Scientists from the Lodz University of Technology discovered after experiments that cold plasma has a repelling effect on water molecules similar to the “lotus effect”. The fabric treated with cold plasma is like a layer of wax and has hydrophobic properties. When water drops are applied, they will have a repulsive rather than absorbing effect.
Members of the new waterproof fabric research team introduced to us the process of “waxing” fabrics using cold plasma technology. “The so-called cold plasma refers to the ionized gas generated under low pressure conditions. We use it to create a lotus effect on the surface of the fiber that repels water molecules to achieve the effect of waxing the fabric.”
This new technology will only affect the molecular structure of the surface layer of the fabric without changing its internal structure. This means that warmth and comfort will not be affected once the garment is made. . Although this technology can currently only be applied to fabrics of 5 cm x 5 cm, a member of the research team said that jackets made using cold plasma technology may be available in the near future. “Although we can only produce small samples of waterproof fiber at present, our cooperative company is currently developing a larger reaction machine. Once the new reaction machine is successfully developed, we will be able to produce jackets made of fully waterproof fabrics. ”
Waterproof fabric is a new type of textile fabric, which is made of polymer waterproof and breathable material (PTFE membrane) plus cloth composite fabric. The main functions of waterproof and breathable fabrics are: waterproof, moisture-permeable, breathable, insulating, windproof, and warm. In terms of production technology, the technical requirements of waterproof and breathable fabrics are much higher than that of ordinary waterproof fabrics; at the same time, from a quality point of view, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. Waterproof and breathable fabrics not only enhance the air-tightness and water-tightness of the fabric, but also have unique breathable properties that can quickly discharge water vapor inside the structure, avoid mold breeding in the structure, and keep the human body dry at all times. It perfectly solves the problem of breathability, windproof, waterproof, It is a new type of fabric that is healthy and environmentally friendly.
Real waterproof fabrics can withstand the pressure of water seepage even if they are exposed to humid climates for a long time without water seepage. For example, if you walk outdoors in windy and rainy conditions for a long time, or kneel or sit on wet ground, there will be no water leakage.
