High-toughness screen cloth containing high-strength polyester fibers inside

The utility model discloses a high-toughness screen cloth containing high-strength polyester fibers inside, which comprises a base cloth layer, a dredging layer is arranged on the outer side of the base cloth layer, a deodorizing layer is arranged on the outer side of the dredging layer, an elastic layer is arranged on the outer side of the deodorizing layer, and the elastic layer is formed by weaving mixed yarns in a mutually alternate up-and-down manner. According to the high-strength polyester fiber blended yarn, on the basis of two high-strength polyester fibers which are wound with each other, polyolefin fibers and polyacrylonitrile fibers are spirally wound on the outer sides of the high-strength polyester fibers to form the blended yarn, and the blended yarn has the advantages thatthe blended yarn can be used for spinning the high-strength polyester fibers, so that the high-strength polyester fiber blended yarn can be formed; the elastic layer is formed by weaving the mixed yarns in a staggered mode, s
