The invention discloses a method for weaving industrial velvet. The method for weaving the industrial velvet comprises the steps of weaving velvet grey cloth and finishing the velvet grey cloth. The velvet grey cloth comprises an upper base cloth, a lower base cloth and velvet warp yarns; and the velvet warp yarns return to the lower base cloth for consolidation weaving after the being subjected to consolidation weaving on the upper base cloth, and then return to the upper base cloth to connect the upper base cloth with the lower base cloth. According to the method, in the weaving of first pile warp from first weft to sixth weft, the whole process is carried out between second warp and third warp, weaving points are the same, and the first pile warp is always clamped by the second warp andthe third warp, so that the pile fastness is improved. One end of the first pile warp is arranged between twelfth weft and first weft, the other end of the first pile warp is arranged between sixth weft and seventh weft, the two wefts are arranged in a shed, the first pile warp is firmly clamped, and the pile fastness is improved. The weaving method provided by the invention can remarkably improve the velvet fastness and is particularly suitable for weaving industrial velvets such as glass fiber velvets and carbon fiber velvets.
