The present invention relates to a fabric warm filling material with a function similar to down, and a preparation method and application thereof. In the present invention, the silk is dissolved to obtain a mixed solution; the mixed solution is immersed in propanol to obtain a wet gel, the solvent in the wet gel is replaced, and then dried to obtain a flexible silk aerogel, which is similar to the down function. Fabric thermal insulation filling material; the fabric thermal insulation filling material is placed between two layers of polyester fiber fabrics, stitched with needle and thread, and the fabric thermal insulation filling material is wrapped in the polyester fiber fabric to obtain a flexible silk aerogel thermal insulation fabric. The silk aerogel prepared by the invention does not need to be added with other modifiers such as softeners, shows good flexibility, and can be used as a filler for thermal clothing. The invention prepares the silk into aerogel, which is used for the filling of the thermal clothing, broadens the new use of the silk, and has a good application and promotion prospect. |
