Net, heat treatment device for net and heat treatment process for net

The invention discloses a net. According to the technical scheme, the net is characterized in that the net comprises a plurality of net units, wherein the net units are connected with one another to form a whole net surface in an arrayed way, four side threads of each net unit are the same in length, four side threads of each net unit are woven jointly by a plurality of strands of twisted threads,and the length of the side threads on the net units is 2-4 cm, cross-shaped cross ropes are arranged in meshes of the net units, and the side threads in the net units and the cross ropes are made ofnylon; when the design is adopted for the net, the net is used as an anti-bird net and birds fly to the net surface, because the length of the side threads on the net units is 2-4 cm, the net is madeof the nylon and the cross ropes are further arranged in the net units, experiments found that the probability can be reduced that birds are hooked and get hurt; in addition, because the length of theside threads on the net uni
