This invention provides a method for preparing a core-sheath structured adsorbent fiber, comprising the following steps: S1. Preparation of the sheath spinning solution: Ethyl cellulose porous microspheres are added to polyester chips and melted and mixed uniformly to obtain the sheath spinning solution; S2. Preparation of the core spinning solution: Porous tea powder loaded with mussel protein is added to a cellulose solution to obtain the core spinning solution; S3. Preparation of the core-sheath structured adsorbent fiber: The sheath spinning solution and the core spinning solution are respectively added to the two feeding ports of a co-rotating twin-screw extruder. The two solutions are extruded through the co-rotating twin-screw extruder, then metered by a metering pump and fed into a spinning assembly for wet spinning through a spinneret, resulting in a composite fiber with cellulose as the core and polyester as the sheath. This invention utilizes a core-sheath structure, where the sheath contains a porous structure, and the core is composed of porous tea powder, mussel protein, and cellulose. The sheath provides adsorption channels, and the core is rich in functional groups such as phenolic hydroxyl groups, which can adsorb odors and provide moisture absorption and wicking properties.
