Embodiment 1
[0048] Embodiment 1 A preparation method of high temperature resistant olive modified nylon fiber includes:
[0049] 1. Preparation of olive leaf modified bilayer microcapsules
[0050] (1) Preparation of the first reaction solution:
[0051] The olive leaf extract was added to a 50% ethanol solution to dissolve for 20min, the temperature was raised to 32°C, then aminopropyltrimethoxysilane, dimethyl carbonate, and vegetable oil were added for stirring, and the stirring speed was 600r / min, and then the temperature was maintained for 10min. to obtain the first reaction solution;
[0052] The mass ratio of aminopropyltrimethoxysilane, dimethyl carbonate and vegetable oil is: 2:1:10; the addition of aminopropyltrimethoxysilane is 10% of the olive leaf extract;
[0053] The vegetable oil is a mixture of safflower seed oil and camellia oil, and the mass ratio is 1:1; the added amount of the vegetable oil is 2 times the quality of the olive leaf extract;
