The hyaluronic acid microcapsule firstly forms a beta-cyclodextrin-metal organic framework, the beta-cyclodextrin-metal organic framework is a porous material formed by natural high molecules and metal ions,the material has a large specific surface area, and pores are mostly micropores; then beta-cyclodextrin-metal organic framework and AgNO3Forming an Ag-beta-cyclodextrin-metal organic framework material by using the aqueous solution, wherein hydroxyl ions are contained in the beta-cyclodextrin-metal organic framework, and when the beta-cyclodextrin-metal organic framework is immersed in AgNO3When in aqueous solution, it may be isolated or act synergistically with cyclodextrin units from AgNO3In-situ ionization of Ag+(ii) a Finally, the Ag-beta-cyclodextrin-metal organic framework material and sodium hyaluronate form a hyaluronic acid microcapsule, the beta-cyclodextrin is a slightly conical hollow cylindrical three-dimensional annular structure consisting of 7 glucopyranose basic units, the upper end (a larger opening end) of the outer side of the beta-cyclodextrin is composed of secondary hydroxyl groups of C2 and C3, the lower end (a smaller opening end) of the beta-cyclodextrin is composed of primary hydroxyl groups of C6 and has hydrophilicity, and a hydrophobic region is formed in the cavity under the shielding effect of a C-H bond, so the beta-cyclodextrin is of a structure with hydrophilic outside and hydrophobic inner cavity. SPAN80 is a water-in-oil type emulsifier, so SPAN80 emulsifier firstly enters the cavity of beta-cyclodextrin, the lipophilic group of SPAN80 is connected with the inner wall of the cavity of the beta-cyclodextrin, the cavity of the beta-cyclodextrin is covered by the hydrophilic group of SPAN80, the polarity of the cavity of the beta-cyclodextrin is enhanced, and sodium hyaluronate can partially enter the cavity of the beta-cyclodextrin and partially graft on the surface of the beta-cyclodextrin. The hyaluronic acid microcapsule has large specific surface area, and the inner surface and the outer surface of a cavity contain sodium hyaluronate and also contain Ag+The microcapsule-like composition of (a). The large specific surface area of the silver-colored adhesive enables the colored adhesive fibers and the hyaluronic acid microcapsules to be combined together more easily and more firmly under the action of the adhesive+The fabric prepared by the method is not easy to fall off, has long-term antibacterial performance, greatly improves the durability of the antibacterial function of the knitted fabric, and still has excellent antibacterial performance after repeated washing; and the sodium hyaluronate can stably and slowly release the moisturizing performance of the sodium hyaluronate when stored in the cavity of the beta-cyclodextrin, so that the service life of the sodium hyaluronate is prolonged. The applicant finds that when the addition amount of the hyaluronic acid microcapsules has certain influence on the mechanical property of the colored yarn, the hyaluronic acid microcapsules are addedThe mechanical property of the colored yarn is firstly increased and then reduced by increasing the addition amount. The possible reasons are: the hyaluronic acid microcapsules and the colored viscose fibers form a pseudo-network structure, so that the mechanical property of the hyaluronic acid microcapsules is improved, but when the content of the hyaluronic acid microcapsules is too much, the effect of molecules among the colored viscose fibers is reduced, and the mechanical property of the hyaluronic acid microcapsules is reduced.
