Skin-core structure fibers with both infrared and radar stealth, a preparation method therefor, and the use thereof are provided. The fibers are as follows: a core material of the skin-core structure fibers comprises the following raw materials in parts by weight: 10 parts of paraffin; 0.7-1.5 parts of an electromagnetic wave absorbent; and 1 part of a high-molecular polymer, wherein the electromagnetic wave absorbent is one or more of ferroferric oxide-intercalated graphene oxide, nano ferroferric oxide and carbon black, and wherein the skin-core structure fiber is obtained by spinning the core material with a skin-layer material.

The present application provides a preparation method for a core-shell structured tungsten/gadolinium oxide functional fiber for X and γ ray protection, comprising: first preparing a core-shell structured tungsten/gadolinium oxide powder; preparing a W@GdO/PP blended melt from the powder; and preparing a W@GdO/PP composite fiber from the blended melt. The core-shell structured tungsten/gadolinium oxide functional fiber prepared by the method can play a role in synergistic protection in the aspect of radiation protection, eliminate a weak protection area, and effectively absorb secondary radiation generated by radiation. Secondly, the prepared functional fiber has the characteristics of no lead and light weight, and has good application prospects in the aspect of X and γ ray radiation protection.
