Stretch Mesh Fabric mesh structure: a model of process innovation and functional improvement

The mesh structure design of stretch mesh fabric is a model of material performance optimization. This seemingly simple pore structure is actually the product of the deep integration of fluid mechanics principles and textile technology. The three-dimensional through mesh formed by a special weaving process builds an efficient air circulation channel to improve the air permeability and moisture removal performance of the fabric. ​
The mesh structure design of stretch mesh fabric is essentially a creative application of aerodynamic characteristics. Its weaving process breaks through the dense structure of traditional fabrics. Through the special parameter regulation of warp knitting, weft knitting or knitting technology, the fibers form regular or irregular hollow areas during the interweaving process. These meshes do not exist in isolation, but are interconnected to form a three-dimensional network. Their pore size, shape and distribution density are all precisely designed. Under a microscope, the fibers at the edge of the mesh present a staggered support mechanical structure, which ensures the stability of the pores and maintains the overall flexibility of the fabric. This structural design allows air to shuttle freely between the meshes, forming an efficient convection channel similar to a honeycomb, laying a physical foundation for the rapid dissipation of heat and moisture.​
From a thermodynamic point of view, the mesh structure significantly improves the heat dissipation efficiency of stretch mesh fabric. The human body continuously generates metabolic heat during activities. Traditional fabrics are prone to form a hot and humid layer on the body surface due to the obstruction of air circulation. The through-type mesh of stretch mesh fabric breaks this barrier. When the outside air flows through the mesh, based on the principle of convection heat transfer, the heat will quickly transfer from the high-temperature body surface to the low-temperature air medium. The mesh structure increases the contact surface area between the fabric and the air, further accelerating the heat exchange process. In the case of intense exercise, the heat generated by the human body per minute can increase the temperature of the area wrapped by ordinary fabrics by 3-5℃, while the stretch mesh fabric can control the temperature fluctuation within 1℃ with its mesh structure, effectively maintaining the thermal balance of the body surface. ​
In terms of moisture management, the mesh structure also plays a key role. The evaporation of human sweat requires sufficient diffusion space, and the mesh system of stretch mesh fabric provides a channel for water molecules to escape quickly. When sweat penetrates the surface of the fabric, the air flow in the mesh will accelerate the vaporization process of water molecules, forming an effect similar to a "micro ventilation system". Compared with the flat evaporation mode of ordinary fabrics, the three-dimensional mesh structure of stretch mesh fabric increases the evaporation efficiency several times. This efficient moisture removal performance avoids the damp and sticky feeling caused by the accumulation of sweat, inhibits the formation of a bacterial breeding environment from the root, and is especially suitable for sports equipment and medical protective equipment. ​
In outdoor sportswear, large mesh areas are usually distributed in sweat-prone areas such as the armpits and back. When the wearer is engaged in activities such as mountaineering and cycling, the air convection formed by the mesh can instantly take away sweat and keep the skin dry; in medical bandage materials, the mesh structure ensures air circulation around the wound surface, reduces the risk of infection caused by a closed environment, and allows wound exudate to be discharged through the mesh to keep the wound clean. These cases confirm the adaptability and innovation of the stretch mesh fabric mesh structure in multiple fields. ​
