How breathable is the 3D fabric ventilation net

source：ptdevesa.com  |  Release time：2025年10月10日
       The breathability of 3D fabric ventilation nets is at a relatively high level in the industry and is one of its core functional advantages. This feature is derived from its unique three-dimensional structure design and material selection, which can be explained from three aspects: "structural principle", "breathability performance", and "scene adaptability"
       From a structural perspective, it is not the "tightly interwoven fibers" of traditional flat fabrics, but rather a continuous three-dimensional hollow channel formed inside the fabric through a "double-layer fabric+intermediate three-dimensional support structure" (such as X-shaped, Y-shaped, and columnar polymer fiber supports) - these channels penetrate the upper and lower surfaces of the fabric, like "micro ventilation ducts", allowing air to flow freely and avoiding the problems of "skin tight and heat accumulation" of traditional fabrics; At the same time, the surface fibers are often designed in a "sparse grid" or "hollow weaving" pattern, further reducing air flow resistance and allowing airflow to quickly penetrate the surface and internal channels of the fabric.
       From the actual breathability performance, its breathability can usually reach 500-2000 L/(㎡· s) (according to industry testing standards), much higher than ordinary pure cotton fabrics (about 100-300 L/(㎡· s)), and its breathability is not affected by pressure (such as when the human body is lying down, the middle support structure can still keep the channel unobstructed and will not be closed due to compression). For example, in the breathable layer of mattresses and the lining of sportswear used in summer, it can quickly take away the heat and sweat moisture emitted by the human body, reduce the feeling of "stuffy sweat and stickiness", and keep the skin dry.
      This high breathability makes it suitable for various scenarios, such as mattresses and sofa cushions in the home field (to enhance the comfort of prolonged sitting/lying), and baby bedding (to avoid sweating and eczema); Running shoe midsoles and sports underwear liners in the sports field (accelerating heat dissipation and moisture removal); The core of filter materials and equipment heat dissipation covers in the industrial field, which balance breathability and support, relies on the efficient air circulation capability brought by the "three-dimensional hollow structure" to meet the needs of "breathability, heat dissipation, and moisture removal" in different scenarios.
