The indexes of the domestic antistatic clothing fabric are in accordance with the related requirements of GB 12014-2009 antistatic clothing.
The existing antistatic clothing mainly adopts two modes to realize antistatic performance, firstly, yarns spun by mixing conductive fibers are adopted to be woven into the fabric, and although the antistatic performance of the fabric can be improved to a certain extent, the point-to-point resistance of the fabric manufactured by the method can not meet the standard requirement of the antistatic clothing; secondly, the embedded conductive wire is woven to form the fabric, but the method has certain limitation, the method can only reach the level of the B level of the point-to-point resistor, and if a metal conductive medium is adopted, spark is easy to generate, and the index can not meet the standard requirement. Meanwhile, the price of the conductive fiber or the static dissipation material is higher, so that the addition amount of the conductive fiber or the static dissipation material is higher in order to achieve an effective antistatic effect in the prior art, the cost is increased, and the spinning process is complicated. Meanwhile, in the second method, the index fluctuation is large due to the influence of factors such as unstable processing technology and test contact, and the content of the conductive filaments is increased to barely meet the standard requirement, so that the cost and the processing difficulty of the fabric are further increased.

The proportion of the conductive yarn in the fabric can be reduced on the premise that the integral antistatic performance of the fabric is ensured by the blended structure of the conductive fiber and the non-conductive fiber, and the cost in processing the antistatic fabric is effectively controlled.
Further, the length of the first conductive fiber is more than 100m, so that continuous passage of a long path on the yarn can be effectively realized.
Further, the length of the second conductive fiber is 2 cm-20 cm, the length can be processed into yarn with twist through a spinning process, the subsequent processing and the weaving into fabric are facilitated, and the smooth proceeding of the spinning and uniform mixing process and the formation of conductive hairiness can be effectively ensured due to the fineness of 0.5D-20D.
Further, the first conductive fiber has a resistance of 1×10 5 ～1*10 7 The resistance of the second conductive fiber is 1 x 10 5 ～1*10 9 The ohm can effectively ensure that a continuous passage is formed in the fabric, and simultaneously ensure that the final passage resistance reaches a higher level in the antistatic index.
Further, the length of the conductive hairiness is 2 mm-10 mm, and the conductive hairiness can extend out of the fabric and form stable contact with the electrode end of an external test instrument.
The antistatic fabric comprises the conductive yarns, wherein the embedding mass ratio of the conductive yarns in the fabric is 2% -30%, the distance between the conductive yarns in the fabric is 0.1 cm-1 cm, the embedding and embedding distance ensures the conducting wire performance, antistatic performance, stable conductive path effect and point-to-point resistance index performance of the fabric, and meanwhile, the cost of manufacturing and processing the fabric can be effectively controlled.
