preparation example 1

[0045] Preparation Example 1 The preparation of sodium carboxymethylcellulose-ethanol gel

[0046] At room temperature, add 0.605 g of sodium carboxymethyl cellulose into 50 mL of ethanol with a mass concentration of 70%, stir and dissolve quickly to obtain a concentration of sodium carboxymethyl cellulose in the mixed solution of 0.05 mol / L, and let it stand for 1 hour. Sodium carboxymethylcellulose-ethanol gel was obtained.

preparation example 2

[0047] The preparation of preparation example 2 agar hydrogel

[0048] 0.25 mg of agar was added to 50 mL of deionized water while heating in a water bath at 45°C, and stirred rapidly to dissolve to obtain a concentration of agar in the mixed solution of 0.5%, and the stirring state dropped to room temperature to obtain an agar hydrogel.

preparation example 3

[0049] Preparation Example 3 Preparation of Sodium Alginate-Ethanol Gel

[0050] Using the same conditions and steps as in Preparation Example 1, the difference is that sodium carboxymethyl cellulose was replaced by sodium alginate to obtain a sodium alginate-ethanol gel.

Abstract

The invention provides a photocatalyst nano fabric finishing liquid. In terms of parts by mass, every 100 parts of the fabric finishing liquid includes 0.1-5 parts of photocatalyst nanoparticles, 1-15 parts of nanoparticle dispersion medium, and 0-0 parts of silica auxiliary. 2 parts, the balance is solvent. The nanoparticle dispersion medium is a network gel, specifically including a combination of fiber network organic gel and network hydrogel; the silica additive is selected from mesoporous nano silica particles or fine silica aerosols One or a combination of two or more glues. The finishing liquid provided by the invention has good physical stability, the finished fabric has good color fastness to soaping, and has good antibacterial properties, the ability to remove TVOC and decompose formaldehyde.

Description

technical field [0001] The invention belongs to the technical field of textile engineering, and relates to an environment-friendly textile fabric finishing solution, in particular to a photocatalyst nano fabric finishing solution, and a preparation method and application of the photocatalyst nano fabric finishing solution. Background technique [0002] Nanophotocatalysis technology, also known as photocatalyst technology, originated in Japan in the mid-1970s. Its principle is to use anatase titanium dioxide (Titanium Dioxide) as a photocatalyst (Photocatalysis) through nanotechnology treatment to generate photoredox under the action of ultraviolet light. The ability to completely decompose microorganisms and chemical pollutants into carbon dioxide and water to achieve the purification of environmental pollutants. After more than 20 years of research and development, the research on this technology has made great progress and has been applied in environmental purification. T...
