How to achieve better breathability and moisture wicking performance in polyester fiber underwear fabrics to improve wearing comfort?

Polyester is a synthetic fiber widely used in underwear fabrics with good elasticity, abrasion resistance and wrinkle resistance. However, its breathability and moisture wicking performance are relatively weak, which affects the wearing comfort to a certain extent. In order to improve the breathability and moisture wicking performance of polyester fiber underwear fabrics, we can start from the following aspects:

1. Fiber modification and mixed spinning
Development of functional polyester fibers: Develop polyester fibers with moisture wicking functions through chemical modification or copolymerization technology. For example, adding hydrophilic groups (such as polyether segments) can improve the hygroscopicity of fibers.
Mixed spinning: Mix polyester fibers with other natural fibers (such as cotton, bamboo fiber, modal) or functional fibers (such as Coolmax, moisture wicking polyester) for spinning. Natural fibers have good hygroscopicity and breathability, while functional fibers can further improve moisture wicking performance.
Bi-component fiber: Bi-component fiber technology is used, such as combining polyester fiber with nylon or spandex to form a composite fiber. This fiber can quickly conduct moisture through capillary action after absorbing moisture, improving moisture absorption and perspiration performance.

2. Fabric structure design
Mesh structure: Design mesh or breathable holes in the fabric to increase air circulation and reduce the feeling of stuffiness. This structure is particularly suitable for sports bras or summer bras.
Multi-layer structure: Using a double-layer or multi-layer structure design, the inner layer uses hydrophilic fibers (such as cotton or bamboo fibers) to absorb moisture, and the outer layer uses hydrophobic fibers (such as polyester fibers) to quickly conduct moisture and dissipate.
Microporous technology: Use microporous technology to create tiny pores on the surface or inside of the fabric. These pores can quickly conduct moisture and air, improve breathability and moisture absorption and perspiration performance.

3. Post-treatment process
Hydrophilic treatment: Through plasma treatment, hydrophilic coating or chemical modification, the surface of polyester fiber is made hydrophilic, thereby improving moisture absorption and perspiration performance.
Breathable membrane technology: Adding a breathable membrane to the surface or inside of the fabric can prevent moisture from penetrating while allowing water vapor to pass through, thereby achieving good breathability and quick drying effects.
Antibacterial treatment: Adding antibacterial agents or performing antibacterial treatment can reduce bacterial growth, thereby reducing odor and improving wearing comfort and hygiene.

4. Fabric weaving technology
Three-dimensional weaving: Using three-dimensional weaving technology to increase the breathability and elasticity of the fabric. This weaving method can form air channels and improve air circulation.
Seamless weaving: Seamless weaving technology can reduce friction and pressure, and at the same time improve breathability and moisture absorption and perspiration performance through reasonable weaving density and structure.
