Wherein the porous biological raw material powder: polyvinyl alcohol: sodium oleate: the mass ratio of the absolute ethyl alcohol is 1:3: 3: 11.

and (3) fluffing, namely adding the secondarily soaked down feather into a washing machine, adjusting the pH value of the washing machine to 5, setting the temperature to 70 ℃, adding 50g of soybean protein fiber into each liter of water, rotating the washing machine, and finishing rotation after washing for 1.5 h.

And (3) softening, namely adding sodium alginate, polyethylene glycol and serine into a washing machine after fluffing is finished, controlling the addition of 12g of sodium alginate, 5g of polyethylene glycol and 9g of serine into each liter of water, then rotating the washing machine, finishing rotation after washing for 3h to finish washing, and then drying the washed down to obtain the down feather macrofiber containing active ingredients of pericarpium citri reticulatae, orange and pomelo.

Example 4

The down feather bio-fibers containing the active ingredients of tangerine peel, orange and pomelo as described in examples 1-3 were used for testing, while comparative tests 1-2 were set for comparison.

Comparative example 1: the method for preparing the eiderdown macrofiber containing the active ingredients of the tangerine peel, the orange and the pomelo as described in the embodiment 1 is adopted, and the difference is that: in the preparation of the bioactive component, zeolite powder, ethanol and 10% calcium chloride solution are not added, and the bioactive component is obtained by directly dissolving the biological raw material powder with the particle size of 0.5 micron in pure water.

Comparative example 2: the method for preparing the eiderdown macrofiber containing the active ingredients of the tangerine peel, the orange and the pomelo as described in the embodiment 1 is adopted, and the difference is that: the fluffing step is omitted.

The properties of the down feather macrofibers containing active ingredients of tangerine peel, orange and pomelo prepared in examples 1-3 and comparative examples 1-2 are as follows:

all percentages used in the present invention are mass percentages unless otherwise indicated.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
