Functions of sportswear:
The biggest function of sportswear is that it can maximize the potential of athletes during exercise, and it is comfortable to wear during outdoor activities and whether it can protect the human body from injury.
The role of sportswear:
1. Antifouling and easy decontamination
Outdoor sports often walk through the muddy and wet mountains and forests, and it is inevitable for the clothes to get dirty. This requires that the appearance of the clothing should be as difficult as possible to be stained by stains, and once it is 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. The 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.
2. Waterproof and moisture permeability
Sports will emit a lot of sweat, and it is inevitable to encounter wind and rain outdoors. This is a contradiction in itself: it must be able to prevent rain and snow from being soaked, and it must be able to discharge the sweat from the body in time. Fortunately, the human body emits water vapor in a single-molecule state, while rain and snow are liquid water droplets in an aggregated state, and their volume sizes are very different. In addition, liquid water has a property called surface tension, which is the property of gathering its own volume. The water we see on lotus leaves is granular water droplets rather than flat water spots. This is Because there is a layer of waxy hairy tissue on the surface of lotus leaves, water droplets cannot spread and penetrate on this layer of waxy hairs due to the effect of surface tension. If you dissolve a drop of detergent or washing powder into the water droplets, because the detergent can greatly reduce the surface tension of the liquid, the water droplets will immediately disintegrate and spread out on the lotus leaf.
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. Anti-static and anti-radiation
Mountaineering is the core content of outdoor sports. In addition to the primitive jungle, the alpine plateau area above 3000 meters above sea level is generally dry due to low air pressure and easy volatilization of water. Outdoor clothing is basically made of chemical fiber fabrics, so static electricity The problem 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.
4. Warmth
Although the warmth retention is closely related to the thickness of the fabric, the customized outdoor sportswear for group sportswear does not allow the clothing to be too heavy, so it is necessary to keep warm and light to meet the special requirements of outdoor sportswear. 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. Of course, far-infrared ceramic powder, binder and cross-linking agent can also be formulated into a finishing agent, the woven fabric can be coated, and then dried and baked to make the nano-ceramic powder adhere to the surface of the fabric and the yarn. between. This finishing agent emits far-infrared rays with a wavelength of 8-14 ray, and also has health care functions such as antibacterial, deodorant, and blood circulation promotion.
