The invention relates to a production technology of carbon filament beating-up. The production technology comprises the following steps that 1, PAN protofilaments are divided into an upper layer and a lower layer, namely, the PAN protofilament layer containing singular numbers of the protofilaments and the PAN protofilament layer containing even numbers of the protofilaments according to the singular numbers and even numbers through a beating-up machine heald frame; 2, carbon fiber filaments or a weft storage mechanism with the carbon fiber filaments penetrates through openings of the upper layer and lower layer of the PAN protofilaments to make the carbon fiber filaments and the PAN protofilaments woven together; 3, the upper position and the lower position of the heald frame are exchanged, and then the positions of the upper layer PAN protofilaments and the lower layer PAN protofilaments are exchanged; 4, the carbon fiber filaments penetrate through the opening to be woven together with the PAN protofilaments. According to the production technology of carbon filament beating-up, the carbon fiber filaments and the PAN protofilaments are woven together, the problems that due to the fact that the property of the protofilaments is unstable and operation of equipment is unstable, when partial PAN protofilaments are broken, the PAN protofilaments are scattered in the equipment, or due to the fact that the manufacturing precision of the equipment is insufficient, the PAN protofilaments are overlapped, a fire or even an explosion is caused, and the carbon fiber filaments cannot operate normally are solved, the operability during filament breaking is improved, losses are reduced, and personnel safety is improved.
