The invention discloses multifunctional integrated equipment suitable for wet spinning fiber postprocessing. A postprocessing technology comprises the steps of drying, drafting and heat setting. The equipment particularly comprises a drying functional region, a drafting functional region and a heat setting functional region and is an integrated landing structure. The equipment has the advantage that the occupied area is small, the processing effect of industrial production is achieved, and the defects of the postprocessing equipment in the industrial production process that a processing line is lengthy and complex are overcome. The whole size of the equipment is L/W/H=2,500/1,500/2,800 mm, the drafting region and the setting region both adopt the mode that one chamber has multiple purposes, the total drafting multiple is 0-20, and the equipment is suitable for scientific research or small batched product production and amplification experiment in industrial simulation.
