The biggest function of sportswear is to maximize the potential of athletes when exercising, and whether they are comfortable to wear during outdoor activities and whether they
can protect the human body from damage.
Function:
1. Antifouling and easy decontamination:
Outdoor sports people often walk in the muddy and wet mountains and forests, and it is inevitable that the clothes will get dirty. This requires that the appearance of the clothing
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 fiber greatly increases the
surface tension of the fabric, making it difficult for oil and other stains to penetrate into the fabric. Slight stains can be removed with a damp cloth, and heavy stains are easy to
clean. Anti-fouling finishing can not only prevent oil pollution, but also has waterproof and moisture-permeable properties. It is generally called “three-proof finishing” (water-
repellent, oil-repellent, and anti-fouling), which is a relatively practical and effective advanced chemical finishing method. It is often used in the outer layer of clothing and the fabric
finishing of backpacks, shoes, and tents.
2. Waterproof and moisture permeability:
A lot of sweat will be emitted during sports, 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
getting wet, and it must also be able to discharge the sweat emitted by the body in time. Fortunately, the human body emits water vapor in a single molecular state, while rain and
snow are liquid water droplets in an aggregated state, and their volumes are very different. In addition, liquid water has a characteristic called surface tension, which is the
characteristic of gathering its own volume. The water we see on the lotus leaf is in the form of granular water droplets rather than flat water spots. This is Because there is a layer of
waxy hair on the surface of the lotus leaf, water droplets cannot spread and penetrate on this layer of waxy hair due to the effect of surface tension. If you dissolve a drop of
detergent or washing powder into the water droplets, since the detergent can greatly reduce the surface tension of the liquid, the water droplets will immediately disintegrate and
spread on the lotus leaves.
Waterproof and moisture-permeable clothing uses the surface tension characteristics of water to coat a layer of PTFE on the fabric (the chemical composition is the same as that of
the “corrosion-resistant fiber king” polytetrafluoroethylene PTFE, but the physical structure is different) to enhance the surface tension of the fabric. The chemical coating makes the
water droplets tighten as much as possible without spreading out and infiltrating the surface of the fabric, so that they cannot penetrate the pores on the fabric tissue. At the same
time, this coating is porous, and the water vapor in the monomolecular state can be smoothly distributed to the surface of the fabric through the capillary channels between the
fibers.
3. Antistatic and anti-radiation
Mountaineering is the core content of outdoor sports. In addition to the primitive dense forests, the high mountains and plateaus above 3,000 meters above sea level are generally
relatively dry due to low air pressure, moisture is easy to volatilize, and outdoor clothing is basically made of chemical nanofiber fabrics. Therefore, the problem of static electricity is
more prominent. The hazards of static electricity are generally manifested as easy fluffing and pilling of clothes, easy contamination of dust and dirt, electric shock and sticky feeling
when close to the skin, etc. If you carry sophisticated electronic instruments such as electronic compass, altimeter, GPS navigator, etc., it may be disturbed by the static electricity of
the clothing and cause errors, which will bring serious consequences.
4. Warmth retention:
Although the warmth retention is closely related to the thickness of the fabric, it is not allowed to be too heavy for outdoor sports, so it must be both warm and light to meet the
special requirements of outdoor sports clothing. The most common method is to add special ceramic powders such as chromium oxide, magnesium oxide, and zirconia to synthetic
fiber spinning solutions such as polyester, especially nano-scale fine ceramic powders, which can absorb visible light such as sunlight and convert it into Heat energy can also
reflect the far infrared rays emitted by the human body itself, so it has excellent heat preservation and heat storage performance. Of course, the far-infrared ceramic powder, binder
and crosslinking agent can also be formulated as a finishing agent, and 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 圱, and also has health care functions such as antibacterial,
deodorizing, and promoting blood circulation.
