The invention belongs to the technical field of synthetic fiber production, and relates to a spinning assembly, in particular to a double-ended composite chemical fiber spinning assembly, which is used for solving the technical problems of unreasonable design and the like of the prior art. The double-ended composite chemical fiber spinning assembly comprises a feeding plate, a distributing assembly and a yarn spray plate which are arranged in sequence, wherein the feeding plate is provided with a first component feeding structure and a second component feeding structure. The double-ended composite chemical fiber spinning assembly is characterized in that: the first component feeding structure comprises a first feeding hole and a second feeding hole of the same structure and size; and the second component feeding structure comprises a third feeding hole and a fourth feeding hole of the same structure and size. Compared with the prior art, the double-ended composite chemical fiber spinning assembly has the advantages of reasonable structure, simple structure and fundamental elimination of fineness difference existing between two bundles of spun yarns since the flow of each feeding hole can be controlled separately and accurately.
