AI Technical Summary
Existing knitted fabrics are insufficient to meet the varying breathability requirements under different circumstances, especially the need for higher breathability during movement.
The fabric employs a specific weft-insertion structure and elastic yarn design, forming a mesh structure through the padding movement of the combed yarns. It also uses elastic yarn composed of polyester and nylon fiber bundles to ensure that the fabric shrinks under normal conditions and expands when stretched, thereby improving breathability.
It remains in a contracted state under normal conditions, significantly improves breathability when stretched, and ensures uniform deformation to meet breathability requirements in different scenarios.
