Embodiment 1

[0021] A preparation method of aging-resistant silk fiber, carried out according to the following steps:

[0022] Step 1: Mix γ-cyclodextrin, o-iodobenzoic acid, and dimethyl sulfoxide at a mass ratio of 7.5:4:100, and after complete dissolution, react the solution in an ultrasonic water bath at 45°C for 12 hours; filter after reaction, Take the filtrate, stir and dilute the filtrate 45 times with acetone, filter again, take the solid, and dissolve it with water 32 times the solid mass, then filter it for the third time, take the filtrate, and dry it to obtain γ-cyclodextrin monoaldehyde ,spare.

[0023] Step 2: Part of the γ-cyclodextrin monoaldehyde prepared above is prepared as a γ-cyclodextrin monoaldehyde solution with a mass concentration of 5%, and a mass of γ-cyclodextrin monoaldehyde is added to the γ-cyclodextrin monoaldehyde solution. Silver nitrate with 0.4 times of refined monoaldehyde, after stirring evenly, control the pH value of the solution at 5, under the c...

Embodiment 2

[0030] A preparation method of aging-resistant silk fiber, carried out according to the following steps:

[0031]Step 1: Mix γ-cyclodextrin, o-iodylbenzoic acid, and dimethyl sulfoxide at a mass ratio of 5:3:100, and after complete dissolution, react the solution in an ultrasonic water bath at 40°C for 16 hours; filter after reaction, Take the filtrate, stir and dilute the filtrate 40 times with acetone, filter again, take the solid, and dissolve it with water 30 times the mass of the solid, then filter it for the third time, take the filtrate, and dry it to obtain γ-cyclodextrin monoaldehyde ,spare.

[0032] Step 2: Part of the γ-cyclodextrin monoaldehyde prepared above is prepared as a γ-cyclodextrin monoaldehyde solution with a mass concentration of 4%, and a mass of γ-cyclodextrin monoaldehyde is added to the γ-cyclodextrin monoaldehyde solution. Silver nitrate with 0.3 times of pure monoaldehyde, after stirring evenly, control the pH value of the solution at 4, under the...

Embodiment 3

[0038] A preparation method of aging-resistant silk fiber, carried out according to the following steps:

[0039] Step 1: Mix γ-cyclodextrin, o-iodobenzoic acid, and dimethyl sulfoxide at a mass ratio of 10:5:100. After completely dissolving, react the solution in an ultrasonic water bath at 50°C for 8 hours; filter after reaction, Take the filtrate, stir and dilute the filtrate 50 times with acetone, filter again, take the solid, and dissolve it with water 35 times the mass of the solid, then filter it for the third time, take the filtrate, and dry it to obtain γ-cyclodextrin monoaldehyde ,spare.

Abstract

The invention relates to field of textile materials, and discloses a preparation method of aging resistant silk fibers. The preparation method comprises the following steps: 1, preparing gamma-cyclodextrin monoaldehyde; 2, preparing silver-loaded gamma-cyclodextrin monoaldehyde; 3, preparing cellulose-fibroin-titanium dioxide xerogel particles; 4, grafting the silk fibers; 5, carrying out impregnated finishing on the silk fibers. The silk fibers prepared by the invention can effectively delay the aging of the silk fibers and avoid borer plaque and bacterial plaque, and further has long aging. In addition, the preparation method of the aging resistant silk fibers can keep the original flexibility of silk and enhance the tensile strength of the silk, and is environment-friendly and harmless, and further does not affect human bodies.

Description

technical field [0001] The invention relates to the field of textile materials, in particular to the field of silk fibers. Background technique [0002] Silk is a continuous long fiber formed by the solidification of the silk liquid secreted by cooked silkworms when they make cocoons. It is also called natural silk. It is a natural fiber and one of the earliest animal fibers used by humans. Silk is light and slender, the fabric has good luster, is comfortable to wear, feels smooth and plump, has poor thermal conductivity, moisture absorption and breathability, and is widely used in weaving various satins and knitwear. However, since the main component of silk is animal protein, its texture is relatively fragile, and it is prone to yellowing and hardening after prolonged exposure to light; on the other hand, silk fibers are also susceptible to microorganisms. The erosion of insects not only affects the appearance and feel, but also accelerates the aging of silk fibers, reduc...
