A method of reversible swelling and collapsing of the latent pores of natural fiber welded biopolymer by way of sequential solvent treatment to i) regenerate mesoporous biopolymeric structures, comprising the steps of providing a nonporous natural fiber welded biopolymer composite, submerging the nonporous composite in polar solvent, exchanging submersion solvents, typically starting from a solvent of polar identity and ending with a solvent of nonpolar identity, then removing the solvent; and ii) regenerate nonporous biopolymeric structures, comprising the steps of providing a mesoporous natural fiber welded biopolymer composite, submerging the mesoporous composite in polar solvent, then removing the solvent. A mesoporous biopolymeric structure wherein the NFW nonporous composite expresses a BET surface area change of <5 m.sup.2 g.sup.1 to >40 m.sup.2 g.sup.1. A nonporous biopolymeric structure wherein the NFW mesoporous composite expresses a BET surface area change of >40 m.sup.2 g.sup.1 to <5 m.sup.2 g.sup.1.

The disclosure provides a treatment method for thermal storage goose down and its disclosure in preparing aviation suit, comprising the following steps: screening, degreasing, washing and squeezing the goose down in sequence to obtain goose down raw materials, mixing potassium thiocyanate, octadecyl isothiocyanate and water and stirring until uniform, mixing nano titanium carbide powder, vinyl modified siloxane, dispersant and water and stirring until uniform, using the primary modified solution and the secondary modified solution to perform padding treatment on the goose down raw material in sequence, the goose down obtained after the secondary modification is rinsed and vacuum dried to obtain the finished thermal storage goose down. The disclosure performs two modification treatments on goose down, only uses phase change materials to give the goose down good light-to-heat conversion performance, improves the fluffiness of the goose down by enhancing the breaking strength and resilience of the goose down.
