Embodiment 1
[0048] A method for preparing olive-containing ES fiber, comprising: preparation of olive extract, preparation of molecular nest particles, preparation of molecular nest particles containing olive extract, preparation of cortex material, preparation of core material, spinning, post-treatment .
[0049] For the preparation of the olive extract, a predetermined number of olive leaf extracts and olive fruit extracts are mixed, ground to 150 mesh; put into 10 times the volume of absolute ethanol, stirred at 100RPM for 10min, heated to 40°C, and Ultrasonic extraction for 2 hours, and the solid matter was filtered out to obtain the olive extract.
[0050] For the ultrasonic extraction, the ultrasonic frequency is 22kHz, and the ultrasonic intensity is 10W / cm 2 , Ultrasonic power 350W.
[0051] The weight ratio of the olive leaf extract: olive fruit extract is 2:1.
[0052] The olive leaf extract has an oleuropein content of 33.4%, a hydroxytyrosol content of 17.1%, and a mesh siz...
