As far as consumers are concerned, the functions of casual wear and sportswear are different from those of professional sportsmen, who emphasize easy maintenance, waterproof and windproof comfort.
Four elements of the basic functions of sportswear:
1. Protection function: windproof and waterproof.
2. Isolation function: keep warm.
3. Moisture permeability and air permeability: to ensure that the heat emitted by the human body can be discharged to the body through the fabric.
4. Flexible function: provide athletes with running and jumping needs.
The human body operates at 37°C under normal conditions. During exercise, the body temperature will rise and the body heat cannot be discharged, which will cause uncomfortable feeling. The function of human body to wick away perspiration is a normal behavioral response, so the comfortability has a greater relationship with the fabric, which is the demand of consumers for moisture absorption and perspiration.
In the dry state, most fibers can quickly expel body moisture from the skin to the surface of the fabric. But the biggest problem is “sweat”. Compared with man-made fibers, natural fibers have better moisture absorption, but they feel very uncomfortable because they feel wet and sticky. The moisture and sweat produce “stuck together” and cannot be eliminated through the fibers. Therefore, comfortable fabrics must meet the following requirements:
1. Like the skin, it can adjust temperature and humidity and maintain a comfortable feeling.
2. Good moisture absorption and moisture permeability.
3. No odor, no skin irritation.
4. Good extensibility, does not affect the stretching of the body.
5. Light weight.
