What are the characteristics of outdoor clothing
1. Warmth
Although the warmth is closely related to the thickness of the fabric Yes, but outdoor sports do not allow clothing that is too heavy, so it is necessary to keep warm and light to meet the special requirements of outdoor sports clothing. The most common method is to add special ceramic powders containing chromium oxide, magnesium oxide, zirconia and other special ceramic powders, especially nano-scale fine ceramic powders, into the spinning solution of synthetic fibers such as polyester, which can absorb visible light such as sunlight and convert it into It can also reflect the far infrared rays emitted by the human body itself, so it has excellent thermal insulation and heat storage performance.

2 , Waterproof and moisture-permeable
Sports will emit a lot of sweat, and outdoor weather will inevitably encounter wind and rain. The released sweat is discharged. Waterproof and breathable clothing is to use the surface tension characteristics of water to coat the fabric with a layer of PTFE (the same chemical composition as the ‘king of corrosion-resistant fibers’ polytetrafluoroethylene PTFE has the same chemical composition but different physical structure) to enhance the surface tension of the fabric. The chemical coating makes the water droplets tighten as much as possible without spreading and infiltrating the surface of the fabric, so that the pores on the fabric cannot be penetrated. At the same time, the coating is porous, and the water vapor in the single-molecule state can be smoothly emitted to the surface of the fabric through the capillary pores between the fibers.
3. Antibacterial and deodorant properties
Due to the characteristics of exercise, sweat and sebaceous glands secrete a lot. In outdoor conditions, it is impossible to change clothes frequently. Under suitable temperature and humidity environment, microorganisms will multiply, causing indecent odors and itching. Therefore, regular outdoor sports clothing is chemically finished with antibacterial and deodorant. The way of finishing is generally to fix the organic quaternary amine type, imidazoline type surfactant or heavy metal ions such as silver and copper on the fiber through resin and cross-linking agent with bactericidal effect, so that it has a certain washing resistance. Of course, an important principle for choosing a fungicide must be non-toxic or low-toxic, otherwise it will be the last resort.
4. Antifouling
Outdoor sports often walk through the muddy and wet mountains and forests, and it is inevitable for the clothes to get dirty, which requires The outer surface of the garment should be as difficult as possible to be stained by stains, and once stained, it should be easy to wash and remove. Changing the surface properties of the fibers greatly increases the surface tension of the fabric, making it difficult for oil stains and other stains to penetrate into the fabric. Slight stains can be removed by wiping with a damp cloth, and heavier stains are also easy to clean. Antifouling finishing can not only prevent oil pollution, but also has the performance of waterproof and moisture permeability. Commonly used in the outer layer of clothing and the fabric finishing of backpacks, shoes and tents.
5. Antistatic
Mountaineering is the core content of outdoor sports. In addition to the original jungle, the high mountain plateau area above 3000 meters above sea level is due to the low air pressure. , moisture is easy to volatilize, the environment is generally dry, and outdoor clothing is basically made of chemical fiber fabrics, so the problem of static electricity is more prominent. The hazards of static electricity are generally manifested in that clothes are prone to pilling, easily contaminated with dust and dirt, and there is electric shock and stickiness when close to the skin. If you carry sophisticated electronic instruments such as electronic compass, altimeter, GPS
navigator, etc., it may be disturbed by the static electricity of clothing and cause errors, which will bring serious consequences.
Types of outdoor clothing
1. Inner clothing
Inner clothing is also known as row Sweat layer, shirts, underwear, underwear, socks, T-shirts and other clothing that stick to the skin. Basically, materials such as Supplex, Coolmax or Cooldry are used. The special fiber structure of these materials has a strong siphon function, which can export the sweat close to the skin to the outer layer and quickly maximize the surface to maximize the sweat. The inner layer realizes the requirement of perspiration and quick drying. It can make the wearer have a dry feeling. Sweat-wicking underwear also has long-sleeved and different thickness types. For lower limbs, there are general shorts and long sanitary pants.
2. Thermal layer clothing
The thermal layer clothing is also called the middle layer. The main function of this layer is to isolate the human body from direct contact with the outside cold air. Avoid cold or even loss of temperature. It has strong windproof, breathable and warm properties. This kind of product has the advantages of fast perspiration, light weight, keeping warm even if it is too wet, and can be squeezed at will without deformation. The almost no thermal effect after that is its major disadvantage.
3. Layered clothing
The layered clothing, also known as the barrier layer, is located in the outermost layer of the three-layer system and is the first to resist the outside wind, snow and In heavy rain, the most ideal is a layer of waterproof and breathable outerwear, such as soft shells, cotton coats, and down jackets, which are all good windproof and warm clothing.
