Functional Fabrics Of Sportswear Based On Fabric Knowledge

1. Fastness

motion clothing It should have good fastness performance, including tensile breaking strength, tearing strength, top crack strength, wear resistance, heat resistance and sunlight resistance. Many modern sports events, people often do a large range of movements, which requires that the sportswear has good flexibility, increase the range of joint and muscle activity, so modern sports clothing often uses high elastic knitted fabric. For example, Lycra and Tactel fabrics are used in swimming clothing and cycling clothing. The wear resistance of sportswear is also an extremely important index. Cordura fiber developed by DuPont company is a kind of air-jet textured high-strength nylon. This product is light in weight, wear-resistant and durable. Its wear resistance is twice that of ordinary air-jet textured nylon, and its wear resistance is 2-7 times of that of poly (phthalamide), poly (vinyl acetate) and cotton.

2. Comfort performance

After wearing the human body, a certain temperature and humidity environment is formed between the human body and the clothing. The environmental index and the physical and chemical performance index of the material determine the comfort degree of the human body.

(1) thermal performance

　　 Athletic Wear Good thermal insulation can prevent athletes from getting cold or frostbite in cold conditions, such as skiing, mountaineering and other sports. In order to improve the thermal insulation of the fabric, hollow fibers that can prevent cold air from entering and can also discharge moisture can be used, and some fabrics with far-infrared fiber can also be used. At present, Thinsulate and other materials produced by 3M company in the United States are often used in the market. The thermal insulation performance is obviously better than cotton, down and wool.

(2) waterproof and air permeability

Many modern sports are outdoor sports, which may cause the athletes to be attacked by wind and rain, such as mountaineering, outdoor running, rowing and other sports, which need sports clothes with good waterproof and air permeability. Waterproof and air permeability is the performance of fabric that can prevent liquid water from passing through and allow gaseous water to pass through. It can not only prevent wind and rain, but also ensure the dryness of human body. At present, fabrics woven from high count and high density yarn are mostly used in the market, and there are also fabrics with diaphragm technology, such as Gore-Tex produced by the famous American Gore company [3].

(3) moisture absorption and perspiration performance

Moisture absorption and perspiration performance is an important performance index of modern sportswear. After a lot of exercise, if the sweat and heat produced by the human body can not be absorbed and discharged in time, the human body will have discomfort and even induce cold and other symptoms. Moisture absorption and perspiration performance is to change the moisture absorption and moisture release properties of fabrics by means of fabric structure design or fiber modification, with water absorption and quick drying. The quick drying speed of Coolmax material produced by yingweida company is 5 times that of pure cotton textile and other light industries Cooldry material produced by the group has strong wicking capacity and excellent moisture absorption and quick drying performance.

3. Special protection performance

Sportswear should also have some special protective properties. Such as skydiving sportswear can be selected in the Textile In the process of anti-static electricity, the anti-static film will be more and more harmful to the health of human body; When running and riding on the road at night, choosing clothes with reflective materials can enhance the night vision effect and ensure the safety of sports.

For different sports, different clothing structures and details should be designed according to the specific sports, ergonomic characteristics and sports environment. In addition, the correct selection of functional fabrics can not only improve the usability of sportswear, but also make the wearer feel comfortable and experience the happiness brought by sports.
