ES fiber containing plant extract and preparation method thereof

The invention relates to ES fibers containing plant extracts and a preparation method thereof, and relates to the technical field of ES fibers.During preparation, the plant extracts, a skin layer material and a core layer material are prepared, the plant extracts obtained in the first step and the skin layer material obtained in the second step are mixed to obtain a mixed skin material, and the mixed skin material and the core layer material are mixed to obtain the ES fibers containing the plant extracts. The preparation method comprises the following steps: preparing a skin material and a core layer material, mixing the plant extracts and the core layer material obtained in the steps 1 and 3 to obtain a mixed core material, spinning and treating the mixed skin material and the mixed core material obtained in the step 4 to obtain ES fibers, separately preparing the plant extracts, the skin material and the core layer material, and fully mixing after the preparation is completed to obtain the ES fibers.
