Mesh cloth: Ingenious design of three-dimensional breathable structure

Mesh cloth breaks the two-dimensional constraints of the tight interweaving of traditional plain fabrics with its excellent breathability. Through the precise control of the density, tension and interweaving rules of the warp and weft yarns, a three-dimensional air circulation channel is created inside the fabric, so that the mesh cloth can achieve efficient breathability while maintaining structural strength.
The construction of the three-dimensional spatial structure of mesh cloth lies in the innovative design of the yarn interweaving method. In order to ensure the tight structure and fabric strength of ordinary plain fabrics, the warp and weft yarns are tightly interwoven in an up-and-down pattern to form a flat and dense surface. This structure restricts the free flow of air. Mesh cloth does the opposite. By adjusting the weaving parameters, it actively creates gaps on the surface of the fabric. In actual production, the reduction of yarn density can directly expand the mesh size, but excessive reduction will weaken the fabric strength; the precise control of tension determines the shape and stability of the mesh, and uneven tension can easily cause the mesh to deform. The change of the interweaving rule is more critical. Through a specific weaving procedure, some yarns are separated from the conventional interweaving path, thereby forming regular or irregular hollow areas in the fabric.
The formation of warp knitted mesh cloth depends on the precise operation of the warp knitting machine. The yarn guide needle is the core component, which guides the yarn to shuttle between multiple needle beds during the knitting process. When the yarn forms a coil around the knitting needle and interlaces with each other, a three-dimensional mesh structure is constructed. In this structure, the size, shape and interconnection method of the coil jointly determine the shape and breathability of the mesh.
The weft knitted mesh cloth achieves a unique hollowing effect through the needle selection mechanism. According to the preset program, the needle selection mechanism controls some knitting needles not to participate in the knitting process, so that the yarn cannot form a normal coil, but exists on the fabric surface in the form of floating lines. These floating line areas are intertwined with the normal knitting area to outline a mesh of a specific shape. Because the weft knitting process is flexible in controlling the local knitting density, the gradual design of the mesh size and shape can be easily realized to meet the differentiated needs of different application scenarios for breathability and mechanical properties.
The three-dimensional spatial structure gives the mesh cloth a unique breathability mechanism. Compared with the flat mesh that only forms openings on the surface of the fabric, the three-dimensional mesh structure constructs criss-cross air channels inside the fabric through the winding and interlacing of yarns. When the outside air contacts the fabric, it can not only quickly enter from the surface mesh, but also flow freely inside the fabric through the three-dimensional channels.
From the parameter control of the weaving process to the innovative application of warp knitting and weft knitting technology, the construction of the three-dimensional spatial structure of Mesh cloth is the result of the deep integration of materials science and textile engineering. This structural design not only redefines the breathability performance standard of the fabric, but also opens up a new direction for the development of functional textiles, making it show irreplaceable value in sports, outdoor, home and other fields.
