Imagine that in the cold winter, you don't have to put on five or six layers of clothes, just put on a thin coat and adjust to a comfortable temperature, you can go out.
At the recent meeting of the American Chemical Society, the US Army Natick Soldier Research said they are working on a technology that can achieve temperature regulation on common fabrics and may eventually enter consumption. market.
In extremely cold weather, soldiers wear up to seven layers of clothes, which makes them feel heavy and inconvenient. Inspired by Stanford University researcher Yi Cui, researchers at the US Army Natick Soldier R&D Center began researching and optimizing fine silver nanowire technology, applying fine silver nanowire coating on common fabrics such as cotton or polyester. Volt electrical energy can generate a lot of heat. They are also developing a control system that allows soldiers to manually control the temperature.
The fine silver nanowire coating does not change the flexibility of the fabric and has also passed the detergent test. They have now made gloves with optimized fine silver nanowire coated fabrics that will soon be applied to clothing.
“We found that if we connect a battery or power supply to the treated fabric, we can increase the temperature of the fabric to 110 degrees, which is a huge change,†said D'Angelo, a researcher at the US Army Natick Soldier Research Center. Of course, the soldiers don't need so much heat, but this shows the potential of the fabric, which can be heated with only three volts. The three-volt battery has only one battery of the watch."
However, the three-volt power is the energy needed to heat a 1 inch x 1 inch fabric. If a whole set of clothes requires more power, the battery becomes a heavy burden. The research center is working with a professor at the University of California, San Diego to develop an elastic stretchable battery that can be incorporated into textiles with virtually no weight.
In fact, there have been a lot of clothes that can adjust the temperature before the market. ClimaWare, founded by MIT student Kranthi Vistakula, uses the Peltier effect (Peltier effect refers to the fact that when there is a current through a circuit composed of different conductors, in addition to generating irreversible heat, at the joints of different conductors When the current direction is different, there will be heat absorption and heat release respectively. One of the two metals connected to each other will release heat, and one will absorb heat. However, ClimaWare is too geek in image, not suitable for ordinary people's daily wear.
In the fall/winter 2016 Paris Fashion Week, the French high-end brand Courrèges showed a series of heated coats with a built-in heating system. Press the button on the cuffs and the back, shoulders and pockets will heat up and can be charged via the iPhone charger.
The first step: look at the color ---- the general quilt cover is divided into two types: jacquard and printing. The two colors are different, but in comparison, the jacquard is more wear-resistant and durable. The prints are diverse, beautiful and beautiful.
Step 2: Touch the texture---When we buy clothes, we often like to touch the fabric of the clothes with our hands. This principle can also be used when we choose a quilt cover. The quilt cover with good texture will be smooth and soft. a feeling of. Perfect contact with the skin.
The third step: smell the smell---what kind of smell can the quilt cover have? If two different grades of quilt cover are put together for comparison, in fact, it is easy to smell the different smells of the two quilt covers, especially the printed quilt covers. You can't smell anything special about the printed quilt cover. If the printed quilt cover is not good, all kinds of strong spices are generally used to cover the impurity smell.
Step 4: Pick the details---If you check carefully enough, you should turn the quilt cover over to check. Many times, the quality of the quilt cover will be reflected here. I found that the meticulous stitching handled, there is no excess thread, and there is no disconnected thread, so in many cases, details are the key to quality.
