First of all, clothing should be able to maintain a comfortable "clothing climate". When the temperature between the skin of human trunk and the inner layer of clothes is about 32℃, the humidity is 50% and the airflow is 25 cm/s, the human body feels the most comfortable, which is called the "standard climate" of clothes. Clothing can block the long-wave infrared rays emitted by human skin and make the inner surface of clothing warm. At the same time, there are many static air layers in clothing textile fibers, which can significantly reduce the heat exchange in clothing and play a role in keeping out the cold. Clothing with good air permeability and hygroscopicity can block the conduction of environmental heat to human skin, but it does not affect the heat dissipation on the body surface, and can play a role in relieving summer heat at high temperature. The permeability and hygroscopicity of cloth can also play a role in adjusting humidity and absorbing harmful substances such as carbon dioxide. Therefore, according to the change of seasons, reasonable selection of clothing, increase or decrease of quantity and corresponding replacement of materials and fabrics can well maintain the "clothing climate" suitable for human body and ensure human health.
Secondly, clothing should have good antifouling performance. With the continuous development of industry, the environmental pollution of human living space is becoming more and more serious, and there are more and more harmful substances, which are more and more harmful to human health. Clothing selection, especially outerwear, should have good antifouling performance and reduce harmful substances from the outside into the living space. Retention time of pollutants such as dust, sewage, bacteria, viruses and greasy chemicals. In the living environment outside the human body, the retention is related to the fabric structure and the amount of charge. The greater the air permeability of the fabric, the rougher and rarer the texture, and the more charged the fabric, the easier it is to be polluted. Generally, synthetic fibers have a lot of charges, so they are particularly prone to dust accumulation. Therefore, when choosing clothes, we must choose clothes made of fabrics with good antifouling performance, especially coats. The fabrics with dense and smooth texture are better, which can reduce the carrying amount of harmful substances and reduce the harm to human health.
In addition, when choosing clothes, be careful not to let clothes constrain people's activities, so pay attention to: First, don't wear too tight. Wearing too tightly has many bad effects on human body. The human body radiates 90% heat through the body surface, and 70% of it radiates heat through radiation convection. If the clothes are too tight in summer, it will affect the convection heat dissipation of body temperature. Make the human body temperature difficult to emit and suffer from heatstroke. In winter, tight clothes and trousers oppress the body parts, which hinders blood circulation, especially the peripheral blood flow, which is not conducive to the evaporation of water on the body surface and the insulation of limbs. It is also easy to cause local oppression and frostbite, leading to cold panniculitis. So don't dress too tightly. Second, the material should be soft, elastic, with a certain compression elasticity and tensile strength, and the hardness should not be too large, so as to ensure free movement, not hinder blood circulation, be easy to dress, and not affect the aesthetic feeling and durability of clothing.
At present, with the strengthening of people's health concept, the design of clothing is becoming more and more diversified, which not only pays attention to the novelty and uniqueness of styles, but also pays attention to the benefits to human health, so that clothing can be truly beautiful, practical and comfortable. I hope my friends will pay more attention to health in their clothes and create a comfortable and healthy clothing environment for their bodies.
