The invention provides a production method of a heat-storage warm-keeping antistatic acrylic fiber and the heat-storage warm-keeping antistatic acrylic fiber with a'skin-core 'structure obtained by the method. The content of the inorganic modifier and the organic modifier in the outer layer of the acrylic fiber is higher than that in the inner layer, or the content of the inorganic modifier and the organic modifier is gradually increased from inside to outside. In the heat-storage warm-keeping antistatic acrylic fiber, the inorganic modifier and the organic modifier can be enriched on the outer layer of the acrylic fiber to form the acrylic fiber with a skin-core structure, a better modification effect is obtained, and the acrylic fiber has very good durability. The acrylic fiber is particularly suitable for being used outdoors in autumn and winter. 本申请提供了一种蓄热保暖抗静电腈纶纤维的生产方法，以及所述方法所得的具有"皮芯"结构的蓄热保暖抗静电腈纶纤维。所述腈纶纤维外层中无机改性剂、有机改性剂的含量高于内层，或者无机改性剂、有机改性剂的含量由内向外逐渐增加。本申请蓄热保暖抗静电腈纶纤维中，无机改性剂和有机改性剂能够富集在腈纶外层，形成皮芯结构的腈纶纤维，获得更好的
