The invention relates to the field of chemical fiber spinning method, and especially discloses a colored FDY strong fiber chip spinning machining process having little pollution and low raw material consumption. The machining process comprises the following specific procedures: after screening chips, carrying out pre-crystallization, then drying, followed by metering and injecting a dried color master batch, next spinning after melt extrusion, carrying out cooling forming, oiling and bundling, then successively passing through a pre-interlacer, a first hot roller, a second hot roller and a primary interlacer, carrying out winding formation, and finally packaging after product inspection. The colored FDY strong fiber chip spinning machining process has simple steps, allows the produced fiber to be a colored fiber, has no need of a post dyeing procedure, decreases input of dyeing raw materials, reduces the production cost, improves the overall production efficiency, has the advantages of low carbon, environmental protection and high color fastness, moreover, can reduce energy consumption, and has obvious effects on energy conservation; and the filament number of the colored FDY strong fiber produced by the process is more than 5 dtexes, and the strength reaches 5.59 cN.
