Reasons why security guards wear winter clothing to keep warm

Thick security clothing winter clothing fabrics have relatively good warmth retention, but this is not the only factor. The warmth of a fabric depends on its ability to transfer heat. Common sense in physics tells us that heat transfer occurs through conduction, convection and radiation. Life experience also shows the comprehensive impact of these three heat transfer methods on the thermal performance of clothing.
Conduction is the transfer of heat through direct contact between objects. Different objects in nature have different heat conduction capabilities, among which still air is the worst. The thermal conductivity of textile raw materials is also different, among which acrylic fiber is the worst and has a small fiber specific gravity and good compression elasticity. The fabric has high bulkiness, so acrylic fabric has good warmth retention. Most of today's home-made quilts use hollow spiral polyester fiber as filler, which is both lightweight and warm, and plays an important role in the still air.
Convection is the transfer and exchange of heat through motion. People will feel warm and comfortable when wearing knitted woolen sweaters indoors where the air is still. However, because woolen sweaters have good breathability, they need to wear a windproof coat in the cold wind outdoors to prevent the flowing air from taking away the body. heat. Therefore, the fiber composition and tissue structure of the fabric have an impact on its warmth retention.
The above is the reason why security clothing in winter is very warm. If you are reading the article, do you understand?
