Embedding conductive filaments or antistatic yarns during weaving

In addition to improving the raw materials, the development of antistatic textiles can also embed conductive filaments (or conductive fiber composite yarns) into the fabric at a certain spacing when the fabric is machine-woven. It can be embedded in the warp or weft direction, or in both the warp and weft directions to form a grid. A large number of experiments have shown that no matter which way the conductive filaments are embedded, the antistatic effect of the fabric is significantly improved, but the best effect is achieved when the conductive filaments or antistatic yarns are embedded in the form of a grid. Moreover, the antistatic performance of the fabric decreases with the increase in the spacing of the embedded conductive filaments. The embedding spacing of the conductive filaments (or the content of the conductive fibers in the fabric) should be determined according to the final use of the antistatic product and the requirements for conductive performance.

Due to the high price of conductive fibers and the high cost of making fabrics, the design should consider using the least conductive fibers to obtain the best antistatic performance. The optimal embedding spacing (conductive fiber content) that meets the product use requirements can be obtained by optimizing the various influencing factors (conductive filament spacing, fabric density, etc.). In addition, since most of the conductive filaments used are black, when designing the fabric structure, the warp points of the conductive filaments should be hidden under the warp points of the base structure to ensure that the fabric structure on the front is not destroyed. On the back of the fabric, the conductive filaments should be exposed on the fabric surface as much as possible to facilitate discharge.
