1. What is the cooling principle of ice silk sleeves
Many people wear ice silk sleeves when they go out in summer, which will feel the arm when wearing them. It’s cool, so why does the ice sleeve feel cool? What is the principle of ice sleeve cooling?
In fact, the so-called ice silk sleeve is a sleeve made of ice silk. Ice silk is viscose fiber, which is alkali cellulose formed by alkalization of natural cellulose and carbon disulfide. The cellulose xanthate is generated, dissolved in dilute lye to obtain a viscous solution, and then made by wet spinning and a series of treatment processes, and has the characteristics of smooth, cool, breathable, antistatic and so on.
But the ice silk sleeve has no cooling effect. The reason why it can make the arm feel cool is because the ice sleeve can keep the cool temperature for a long time, especially if the ice sleeve is placed in the After a period of time in the air-conditioned room, the hollow fibers of the fabric flow to activate the cooling function. After the cold air in the fibers is activated, the unique hollow structure controls the evaporation of water, which can achieve the purpose of cooling faster.
However, it should be noted that the ice silk sleeve is not always cold at all times. It is cooler in cool places and hotter in hot places. Therefore, if it is not for sun protection, it is recommended to wear it outside. Don’t wear ice silk cuffs at this time, because wearing ice silk sleeves over the outside may make your skin feel hotter.
Second, Can ice sleeves really protect against sun?
The main function of ice silk sleeves is sun protection. When going out in summer, strong ultraviolet rays will darken the skin, and in severe cases, the skin will be sunburned. At this time, you need a pair of ice silk sleeves. The sun protection factor of ice silk sleeves is very high, which can absorb certain ultraviolet rays and prevent sunburn. If you are too hot, you can lightly spray some water on the ice sleeves, the effect is Very cool.
Third, can the ice silk sleeves be worn for a long time?
No.
The ice sleeve cannot be worn for a long time, because the ice sleeve is a relatively tight material, it may be uncomfortable to wear for too long, and allergic people may also have allergic reactions; and the material of the ice sleeve is relatively relatively It is sealed, so it is recommended to take it off when resting indoors to avoid hurting the skin.
