preparation example Construction

[0048] Specifically, the preparation method of the present invention comprises the following steps:

[0049] (1) Prepare microcrystal-doped polydopamine solution: dissolve dopamine (preferably use water as a solvent, reduce the use of organic solvents, and be more environmentally friendly); then, under stirring conditions, add polysaccharide microcrystals to obtain polydopamine solution doped with polysaccharide microcrystals;

[0050] Preferably, the polydopamine doped with polysaccharide microcrystals has a concentration of 1-5 g / L;

[0051] In this step, the raw material polysaccharide microcrystals are obtained by oxidation of polysaccharides such as cellulose fibers, chitosan, chitin, or starch;

[0052] Preferably, the polysaccharide microcrystals are obtained by oxidizing polysaccharides such as cellulose fibers, chitosan, chitin, or starch through periodic acid and / or periodate (more preferably with periodic acid obtained by oxidation of salt), and the obtained polys...

Embodiment 1

[0077] 0.1 g of dopamine is dissolved in 100 ml of aqueous solution, and 0.1 polysaccharide microcrystals are added under stirring conditions to obtain a polydopamine solution doped with microcrystals.

[0078] Soak the silk fabric in the dopamine solution doped with microcrystals at a bath ratio of 1:25. At 30°C, the color of the solution gradually changes from colorless to wine red and finally black, then shake and stir at a constant temperature for 0.5-2 hours. , take out and wash the fabric with distilled water and ethanol to obtain a polydopamine-modified silk fabric with microcrystalline doping on the surface.

[0079] The obtained modified silk fabric is placed in a mixed solution containing butyl titanate, isopropanol, nitric acid and deionized water with a bath ratio of 1:50;

[0080] Wherein, the molar ratio of butyl titanate to isopropanol is 1:1.4, the volume ratio of isopropanol to deionized water is 7:3, the volume ratio of nitric acid to deionized water is 1:75,...

Embodiment 2

[0083] 0.1 g of dopamine is dissolved in 100 ml of aqueous solution, and 0.2 polysaccharide microcrystals are added under stirring conditions to obtain a polydopamine solution doped with microcrystals.

[0084] Soak the woolen fabric in the dopamine solution doped with microcrystals at a bath ratio of 1:25. At 40°C, the color of the solution gradually changes from colorless to wine red and finally black, then shake and stir at a constant temperature for 0.5-2 hours. , Take out and wash the fabric with distilled water and ethanol to obtain a polydopamine-modified wool fabric with microcrystalline doping on the surface.

[0085] The modified wool fabric is placed in a mixed solution containing butyl titanate, isopropanol, nitric acid and deionized water with a bath ratio of 1:50;

[0086] Wherein the mol ratio of butyl titanate to isopropanol is 1:1.4, the volume ratio of isopropanol to deionized water is 5:5, the volume ratio of nitric acid to deionized water is 1:75, and the p...

Abstract

The invention provides a preparation method of an anti-fouling and sun-resistant composite functional fabric, a fabric prepared through the preparation method and clothes containing the fabric. The preparation method is based on the concept of bionics, deposits anti-UV nanometer titanium dioxide on the surfaces of fibers according to the combination of the polysaccharide crystallite inductive coupling effect and the biological binding effect of polydopamine, and can produce the anti-fouling and sun-resistant functional fabric through use of a hydrophilic polymer on the fiber surfaces. The biological binding agent polydopamine, biomass polysaccharide crystallite as a coupling agent and hydrophilic aid polyethylene glycol are environmentally friendly and have no pollution on the environment.The preparation method is suitable for silk, wool, polyester and polyamide. The obtained functional fibers have good soaping fastness and antifouling and anti-sunning functions.

Description

technical field [0001] The invention relates to the field of materials, in particular to a preparation method of an antifouling and light-resistant composite functional fabric, the fabric prepared by the method and the clothing containing it. Background technique [0002] Antifouling textiles are playing an increasingly important role in social life, because they fully comply with the concept of "low carbon", have a long service life and a high probability of reuse, and have been widely used in oil fields, maintenance and catering industries. Applications. At the same time, in daily life, in addition to antifouling, textiles are often exposed to sunlight during consumption, and are easily affected by free radicals such as ultraviolet rays and oxygen in the light, resulting in loss of textile strength, decline, and yellow appearance. Use period is shortened. Especially amino-containing protein fibers such as wool and silk are used to make high-end clothing because of their ...
