Anti-arc fabric

The invention provides an anti-arc fabric, which belongs to the technical field of protective fabrics. The anti-arc fabric comprises the following raw materials by weight: 34 to 45% of a modified polyacrylonitrile fiber, 32 to 45% of a cotton fiber, 5 to 15% of a meta-aramid fiber, 3 to 10% of a para-aramid fiber and 1 to 3% of an antistatic fiber. According to the invention, since a weight ratio of the modified polyacrylonitrile fiber to the cotton fiber is controlled to be in a range of 1: 0.82-1.27, ideal tensile and breaking strength and tearing strength are realized, and an excellent flame retardation effect is obtained; since the usage amount of the cotton fiber is reasonable, an excellent moisture absorption effect is obtained, so requirements for comfortable wearing are met; when the gram weight of the fabric is 200 to 290 g/m , arc resistance of the fabric reaches 8 cal/cm .
