The time is entering the cold winter, and many people buy cold clothes, including hot clothes, warm clothes, wool hats, etc. Among them, "hot clothes" is the inner wear choice of many people. It also quickly becomes hot because it is convenient to wear, but do you know what the principle of hot clothes is? What is the difference between heating and heating clothes? How to choose hot clothes? "Enjoy Health Network" specializes in this article to share relevant knowledge about hot clothes, so that only when you wear it right can you really get hot.
What is the principle of hot cherry blossom?Heat-releasing clothes are designed clothes that lock the body's temperature and quickly evaporate sweat, moisture, etc. to achieve the effect of body temperature preservation. Advanced fiber technology is usually used to combine heat-guiding and heat-retaining materials to create a warm-retaining layer that can keep the external low temperature and maintain the internal temperature.
{9 9}Taiwan University Chemical Engineering Ph.D. Xie Jie, a doctor of chemical engineering at NTU, explained on his face fan page that the heat of clothing is the body temperature, and the principle of hot clothing is mainly "far-red outer line radioactivity" and "fiber moisture absorption and heat release":
Far-red outer line radioactivity: Used ceramics and oxides to convert the visible light into the red outer line, achieving a heat-emitting effect; in a different sentence, if light is shined, the light can be converted into heat.
Fiber moisture absorption and heat release: When sweat and water are connected to this type of fiber, the condensed moisture will be absorbed and the condensed heat will be released, thus achieving a heat-producing effect.
Xie Jieyang said that water vapor mainly comes from the human body, and the body temperature turns water into water vapor, condenses back water on the body surface, but only converts the heat in the body to the outside of the body. There is no additional heat energy generated during the process. Therefore, it is said that pulling heat is to use body temperature to "keep warm", rather than really "heat".
The difference between heating and heating clothes?Heat-producing clothes use special materials of fabrics to lock the body's body temperature, so that the water of sweat vapor changes into heat energy, creating a feeling of heat. It is defined that clothes actively provide the body temperature, but if the body heats up and sweat is unable to be discharged, the sweat begins to evaporate, causing the body temperature to drop, and instead you will feel cold.
Heating clothing is aided by special fabrics and soft bristles to retain the warm air layer, allowing the body to be stable and comfortable and warm, while providing efficient moisture absorption and sweat removal function. In terms of definition, clothes help the body maintain a "constant warmth". Whether it is warm depends on the number of transmissions. The lower the number means the heat isolation effect is.
How to choose hot clothes?There are many kinds of materials for heating clothing, such as lambs, tin cotton, polyester fibers, hollow fibers, etc. In terms of clothing materials, "wool" is a natural material that can truly increase temperature, but the price is also relatively expensive. The hot clothing on the market is mostly based on synthetic materials. People can consider it according to their needs, comfort, and price:
Comparison of hot clothing materials:
Rayon: Good skin and strong water absorption, but limited improvement in warmth.
Tencel: Good skin-sensitive and has good moisture absorption and transmission function.
Polyester fiber (Polyester): has a heat-producing effect, but has a high heat-guiding effect and is relatively inconsistent in warmth.
Hollow Fibre: Use fiber holes to prevent heat loss. Although it can improve the temperature preservation effect, it has no heat-promoting characteristics.
Polyacrylonitrile: It feels close to wool and has better warmth than polyester fibers.
Merino wool: effectively prevents heat loss and has better temperature preservation effect, but the price is higher.
Acrylate: It can absorb moisture and heat, but at a higher price.
How to wear hot clothes?Most of the hot-releasing clothes on the market are very thin, mainly worn as underwear and cannot be worn alone. They must be matched with other outer layer clothes, such as vests, jackets, etc. However, if the cold waves come and the air temperature drops, what should I do if my heating clothes are not covered and keep warm? Will wearing 2 pieces really keep warmer?
To wear the best effect of heating clothes, the most important thing is to "stitch the body", because the principle of heating clothes is to create a heat circulation between the body and the clothes. It is recommended to choose the "onion style wear method". The first layer is wearing a hot clothes, the second layer is wearing a bristle clothes, and the outer layer is wearing a thick coat, so that it can keep warm.
Level 1: Sticking in a hot-skinned clothing.Level 2: Wear warm clothing, such as sweaters, bristle vests, etc.
Level 3: Wear windproof clothing to prevent warm air from dissipating.
Can heating clothes be washed?Heating clothes can be washed in a washing machine. However, excessive scrubbing may damage the material of the scrubbing material. It is recommended to put it in the laundry bag and then insert it into the washing machine to select the "Soft Wash" mode to reduce the damage to the clothes. In addition, be careful not to use hot water to clean it, as hot water will damage the material, and may even deform if it is too high. It is recommended to refer to the cleaning marks on the clothes. Can
heating clothes be dried? The same principle as not being able to use hot water to clean it, the high temperature of the clothes dryer can easily destroy the heating structure, and even cause water loss and deformation, resulting in loss of warmth. It is recommended to dry naturally.
Who is not suitable for hot clothes?Wearing hot clothes to get cold, these four types of people may become weaker and weaker! Although hot-releasing clothes have a warm effect, sweating is easy to fall into the clothes, and the result is moist and hot, which may cause problems such as scratching, sweat rash, sweat spots, bacterial infections or folliculitis. It is not suitable for everyone. It is recommended that people with the following conditions should avoid wearing hot-releasing clothes:
Sweat gland development: sweat may cause or rashes due to sweat falling into the clothes.
Acne skin: People who are prone to oily skin, often have acne, and folliculitis, wearing hot clothes may cause folliculitis on the chest and back.
Alitopic dermatitis: This type of patients are originally slow to control temperature and are sensitive to skin, and they will be even more effective if they wear hot clothes.
Winter: The skin is dry and slurry. If you wear a hot-skinned clothing again, it may feel uncomfortable.
