Which Is Cool In Dark And Light Colors And In Several Summer Clothes?

< p > the scorching sun is scorching, sometimes it is too hot for you to wear. The less you wear, the better. Then what color should you wear? < a target= "_blank" href= "http://www.91se91.com/" > clothes < /a >, what kind of fabric can you make yourself cool? The reporter has prepared dark and light colored clothes and several kinds of summer clothes.

Of course, the experimental error is inevitable, the result is for readers only.

< /p >

< p > Experiment 1: which is cool and light colored? < /p >

< p > 30 degrees Celsius clothes for 5 minutes in the sun, dark 34, light color 31.5.

< /p >

< p > reporter prepared two T-shirts of the same style. The fabric is also modle, the color is black and white, and will be placed in the same size and placed in the sun. The initial temperature is 30 C.

5 minutes later, the reporter measured the surface temperature of two clothes. The results showed that the surface temperature of black clothes was 34 degrees, while that of white was only 31.5 degrees.

< /p >

< p > conclusion: don't wear dark clothes under sunlight. < /p >

< p > in the sun, black clothing absorbs more energy from the sun, so the temperature is more obvious. And white and other light colored clothes will reflect much of the sun's light, so the heating is slower.

< /p >

< p > since dark clothes are fast absorbing, can we say that we can not wear summer clothes? For this reason, Huang, a senior physics teacher in a local high school, told reporters that in indoor or cloudy days where temperature is lower than body temperature, dark clothes can be worn, so that the heat on the skin surface can be quickly drained away, and it feels cooler than other colors. In the sun, it is best to choose light colored clothes such as white, otherwise the dark clothes will absorb the heat in the sunlight, which is equivalent to wearing a warm clothes.

< p > experiment two: linen and chiffon, which is cool? < /p >

< p > linen shirt at 33 degrees Celsius, 33.5 degrees Celsius shirt, 34 degrees silk sweater, 34.5 degrees Celsius.

< /p >

< p > the reporter has prepared 4 light colored clothes with different fabrics. They are 100% cotton, 100% hemp, 100% silk and chiffon, and the initial temperature of the clothing surface is 31.5 degrees.

Then, put 4 clothes in the sun for 5 minutes, then test the surface temperature of the clothes, the temperature of the shirt is 33 degrees, followed by the chiffon sweater, the temperature is 33.5 degrees Celsius, then the silk shirt is 34 degrees, the hottest is the cotton sweater, and the temperature is 34.5 degrees.

The results showed that the temperature of the shirt was the lowest.

< /p >

< p > conclusion: linen shirts are the most cool (/p >).

The structure of P is relatively loose, and hemp contains hemicellulose, which absorbs ultraviolet rays. Therefore, linen clothing is indeed cooler than other fabrics.

< /p >

< p > since the chiffon shirt is almost the same as that of the hemp shirt, does it mean that it is almost the same in summer? In fact, in addition to the heat absorption, the moisture absorption of summer clothing material has a great influence on the cooling degree. The clothes with good moisture absorption can absorb human sweat in time, and will not give people the feeling of sticky and sticky.

Therefore, in summer, clothes made of natural plant fiber such as linen, silk, cotton and so on are the best choice. The clothes of chiffon fabrics, though thin, may be stuffy because of their poor breathability and moisture absorption.
