The "grid" in grid anti-static fabric refers to the grid-like structure formed by conductive fibers or conductive threads on the fabric. These conductive fibers are usually evenly distributed on the base fabric of the fabric, forming a regular grid pattern through criss-crossing lines.

The specifications of grid anti-static fabrics usually refer to the size and density of the mesh and the distribution of conductive fibers. These specifications are designed based on specific usage requirements and industry standards, and directly affect the anti-static performance and applicable scenarios of the fabric. Common specifications include the following aspects:

1. Grid size

Mesh size refers to the distance between conductive fibers in the mesh structure. The size of the mesh directly affects the anti-static effect and the applicability of the fabric. Common grid sizes include:

5mm × 5mm: This is a larger grid size and is suitable for environments with less stringent requirements for electrostatic protection, such as ordinary electronic assembly workshops. The larger mesh size gives the fabric good breathability, but the anti-static effect is relatively weak. 

2.5mm × 2.5mm: Medium grid size, suitable for most electronic manufacturing and assembly environments, providing a balanced anti-static performance and comfort. 

1mm × 1mm: Small grid size, often used in industries that are extremely sensitive to static electricity, such as semiconductor manufacturing and precision electronic equipment production environments. The smaller mesh size ensures a denser distribution of conductive fibers, thereby improving the anti-static effect.

2. Grid density

Mesh density refers to the number or distribution density of conductive fibers per unit area. Mesh density directly affects the anti-static effect and breathability of the fabric:

High-density mesh: The mesh spacing is small and the conductive fibers are densely distributed. It is suitable for environments with extremely high electrostatic protection requirements, such as semiconductor and precision electronic equipment manufacturing. High-density mesh provides more comprehensive static protection, but may affect breathability slightly.

Low-density mesh: The mesh spacing is large and the conductive fibers are sparsely distributed. It is suitable for environments with general protection requirements, such as ordinary electronic assembly or chemical industry. Low-density mesh fabric has better breathability and is more comfortable to wear.
