Innovation in breathability of polyester fabric for sportswear: integration of multi-layer structure design and advanced fabric technology

1. Multi-layer structure design
Multi-layer structure design is one of the important means to improve the breathability of polyester fabric for sportswear. This design forms a layered fabric system by stacking fabrics of different materials and functions, thereby optimizing breathability.
Surface breathable fabric:
The surface layer usually uses high breathability materials such as Mesh fabric and CoolMax. Mesh fabric, with its unique mesh structure, can allow air to flow freely, effectively expel moisture from the body, and keep the body dry. CoolMax fabric, through its special fiber structure, can quickly absorb and diffuse sweat, and can also keep the surface of the fabric dry, further improving breathability.
Middle layer insulation and breathability:
The middle layer usually uses fabrics with insulation and breathability functions, such as blended materials of polyester fiber and microfiber. These materials can allow air and moisture to circulate inside the fabric while maintaining a certain degree of warmth, avoiding stuffiness.
The inner layer absorbs moisture and wicks sweat: The inner layer uses fabrics with excellent moisture absorption and perspiration performance, such as specially treated polyester fibers or antibacterial fabrics containing silver ions. These fabrics can quickly absorb sweat from the skin surface and diffuse it to the outer layer of the fabric, and discharge it through the breathable surface layer, thereby keeping the body dry and comfortable.

2. Special cutting and ventilation devices
The design of special cutting and ventilation devices aims to further improve the breathability of sportswear by increasing the air circulation path and adjusting the contact area between the fabric and the skin.
Armpit and back opening design: The armpit and back are areas that are prone to sweating during exercise. By designing openings or vents in these areas, the air circulation can be significantly increased, the evaporation of sweat can be accelerated, and the feeling of stuffiness can be reduced. These openings are usually designed to be adjustable, such as zippers, buttons, etc., so that athletes can adjust them according to the intensity of exercise and personal needs.
Three-dimensional cutting technology: Three-dimensional cutting technology makes the clothing fit the human body curve more closely, reduces the friction and accumulation between the fabric and the skin, and thus increases the air circulation space. This technology not only improves breathability, but also improves the comfort and freedom of movement of clothing.
Breathable belt and mesh splicing:
The use of breathable belts or mesh fabrics for splicing in key parts of clothing, such as waist, cuffs, trouser legs, etc., can further increase air circulation and improve overall breathability. These splicing parts are usually designed to be detachable or adjustable to adapt to different sports scenes and weather conditions.

3. Fabric splicing and functional zoning
The fabric splicing and functional zoning design aims to achieve a balance between breathability and other performance through the combination of different fabrics and functions.
Fabric splicing:
According to the different parts and functional requirements of sportswear, fabrics with different breathability are selected for splicing. Mesh fabrics are used in parts that require high breathability (such as the back and underarms), and thicker polyester fabrics are used in parts that require a certain degree of warmth (such as the chest and abdomen). This splicing design not only improves breathability, but also enhances the adaptability and durability of clothing.
Functional zoning:
Functional zoning design divides sportswear into different functional areas, and each area is selected and designed according to its specific functional requirements. Moisture wicking fabrics are used in areas that require high perspiration (such as the back), and wear-resistant fabrics are used in areas that require increased friction (such as the palms and knees). This design not only improves breathability, but also improves the comfort and functionality of clothing.

4. Combination of brand and technology
In the improvement of fabric design, the combination of brand and technology also plays a vital role. Some well-known brands or manufacturers apply advanced fabric technology and design concepts to sportswear through independent research and development or cooperative research and development, thereby achieving a significant improvement in breathability.
Application of nanotechnology:
Nanotechnology changes the microstructure of the surface of the fabric to make it have better breathability and waterproof performance. Some brands apply nanotechnology to polyester fiber fabrics to form tiny nanopores to achieve rapid circulation of air and moisture.
Three-dimensional weaving technology:
Three-dimensional weaving technology forms a three-dimensional fabric structure by weaving the fabric in three dimensions. This construction not only increases the breathability and elasticity of the fabric, but also improves the comfort and fit of the garment.
