Embodiment 1

[0023] In this embodiment, a fabric thermal filling material with a function similar to down is prepared by the following method, including the following steps:

[0024] (1) Dissolution of silk: Take 14.7g silk to a round bottom flask, add 0.1mol CaCl dissolved in it 2 , a mixed solution of 3mol ethanol and 9mol water; it was continuously stirred at 70°C for 4 hours on a constant temperature electromagnetic stirrer, and the silk was completely dissolved to obtain a mixed solution;

[0025] (2) Preparation of wet gel: Pour the mixed solution containing silk into a mold and immerse in propanol for gelation. The size of the mold is: 800cm×100cm×3cm, and the gelation time is 12 hours. Become a wet gel; then immerse the wet gel in absolute ethanol for replacement; the replacement time is 3 days, and replace the absolute ethanol every day; make the wet gel;

[0026] (3) Drying: Freeze-dry the wet gel at -60°C for 18 hours to obtain flexible silk airgel; that is, a fabric thermal fi...

Embodiment 2

[0029] In this embodiment, a fabric thermal filling material with a function similar to down is prepared by the following method, including the following steps:

[0030] (1) Dissolution of silk: Take 14.4g silk to a round bottom flask, add 0.1mol CaCl dissolved in it 2 , a mixed solution of 2mol ethanol and 8mol water; it was continuously stirred at 70°C for 4 hours on a constant temperature electromagnetic stirrer, and the silk was completely dissolved to obtain a mixed solution;

[0031] (2) Preparation of wet gel: Pour the mixed solution containing silk into a mold and immerse in propanol for gelation. The size of the mold is: 800cm×100cm×3cm, and the gelation time is 12 hours. Become a wet gel; then immerse the wet gel in absolute ethanol for replacement; the replacement time is 3 days, and replace the absolute ethanol every day; make the wet gel;

[0032] (3) Drying: Freeze-dry the wet gel at -60°C for 18 hours to obtain flexible silk airgel; that is, a fabric thermal fi...

Embodiment 3

[0035] In this embodiment, a fabric thermal filling material with a function similar to down is prepared by the following method, including the following steps:

[0036] (1) Dissolution of silk: Take 15g silk to a round bottom flask, add dissolved 0.1mol CaCl 2 , a mixed solution of 4mol ethanol and 10mol water; it was continuously stirred at 70° C. for 4 hours on a constant temperature electromagnetic stirrer, and the silk was completely dissolved to obtain a mixed solution;

[0037] (2) Preparation of wet gel: Pour the mixed solution containing silk into a mold and immerse in propanol for gelation. The size of the mold is: 800cm×100cm×3cm, and the gelation time is 12 hours. Become a wet gel; then immerse the wet gel in absolute ethanol for replacement; the replacement time is 3 days, and replace the absolute ethanol every day; make the wet gel;

[0038] (3) Drying: Freeze-dry the wet gel at -60°C for 18 hours to obtain flexible silk airgel; that is, a fabric thermal filling...

Abstract

The invention relates to a fabric warm-keeping filling material with a down feather-like function and a preparation method and application thereof. The preparation method comprises the following steps: dissolving silk to prepare a mixed solution; and soaking the mixed solution into propyl alcohol to prepare wet gel, replacing the solvent in the wet gel, and then conducting drying to prepare flexible silk aerogel, namely the fabric warm-keeping filling material with the down feather-like function. The fabric warm-keeping filling material is placed between two layers of polyester fiber fabrics, the two layers of polyester fiber fabrics are sewed with needles and threads, and the polyester fiber fabrics are wrapped with the fabric warm-keeping filling material to obtain the flexible silk aerogel warm-keeping fabric. The silk aerogel prepared by the invention does not need to be added with other modifiers such as a softening agent, shows very good flexibility, and can be used as a filler of thermal clothes. According to the invention, the silk is made into the aerogel which is used as a filler of thermal clothes, so that the new application of the silk is widened, and the aerogel has good application and popularization prospects.

Description

technical field [0001] The invention belongs to the technical field of preparation of fabric heat-retaining filling materials, and in particular relates to a fabric heat-retaining filling material with a function similar to down and down, and a preparation method and application thereof. Background technique [0002] Airgel material is a lightweight solid material with a nanoporous network structure, which has the characteristics of high porosity, large specific surface area, ultra-low density, and low thermal conductivity. The advent of aerogels can be traced back to 1931, when Kistler of Stanford University used supercritical drying technology to successfully prepare silica aerogels for the first time. It has been nearly 90 years since the discovery of airgel. The unique properties of airgel make it a research hotspot in the field of materials. At present, there are many types of aerogels, and the widely studied aerogels mainly include inorganic aerogel materials (such a...
