Problems solved by technology

Adding graphene in the slicing stage will easily lead to the agglomeration of graphene, and the process is complicated, and the uniformity of graphene dispersion cannot be guaranteed
In the post-finishing stage, the padding method needs to be added to the organic cross-linking agent, and the amount of graphene combined on the fabric is small, and the binding force is weak; the high-temperature and high-pressure dyeing method, without high-temperature baking, graphene and The bonding force of the fabric is weak, and the washing fastness does not meet the requirements

Embodiment 1

[0041] A graphene-based antibacterial fabric preparation method includes four procedures of fabric pretreatment, dye solution preparation, high-temperature dyeing, and drying and baking that are sequentially set. The specific process is:

[0042]Fabric pre-treatment: the treatment solution contains 1wt% sodium hydroxide and 0.1wt% JFC, and is treated with a bath ratio of 1:20. The treatment procedure is to add polyester fabric to the treatment solution at 35°C and heat up to 85°C. Keep warm for 1 hour, soak in 60°C water for 10 minutes, wash once with 50°C water, and wash with 30°C water until the surface of the fabric is neutral.

[0043] Preparation of dye solution: Dilute the graphene oxide slurry with water, add sodium acetate-acetic acid buffer and BB emulsion (wherein the mass ratio of benzyl benzoate and castor oil polyoxyethylene ether is 1:4), fully stir and mix The graphene oxide content obtained was 0.05g / L, the buffer solution content was 0.20g / L, and the BB emuls...

[0047] A graphene-based antibacterial fabric preparation method includes four procedures of fabric pretreatment, dye solution preparation, high-temperature dyeing, and drying and baking that are sequentially set. The specific process is:

[0048] Fabric pre-treatment: The treatment solution contains 2wt% sodium hydroxide and 0.5wt% JFC, and is treated with a bath ratio of 1:20. The treatment procedure is to add polyester fabric to the treatment solution at 35°C, and heat up to 85°C. Keep warm for 1 hour, soak in 60°C water for 10 minutes, wash once with 50°C water, and wash with 30°C water until the surface of the fabric is neutral.

[0049] Preparation of dye solution: add sodium acetate-acetic acid buffer and BB emulsion (wherein the mass ratio of benzyl benzoate and castor oil polyoxyethylene ether is 2:3), fully stir and mix to obtain a graphene oxide content of 0.10g / L, the buffer solution content is 0.30g / L, the BB emulsion content is the dye liquor of 0.40g / L, and the...

Abstract

The invention provides a graphene-based antibacterial fabric preparation method, comprising the following steps: (1) Fabric pretreatment: soak the fabric with a treatment solution containing lye and a penetrant, and then wash the fabric with water to neutrality; (2) Preparation of dyeing solution: dilute graphene oxide slurry with water, then add buffer solution and BB emulsion, and mix to obtain dyeing solution; BB emulsion is a mixed emulsion of benzyl benzoate and castor oil polyoxyethylene ether; (3) High-temperature dyeing: high-temperature dyeing of the fabric with a certain liquor ratio and the method of temperature programming; (4) drying and baking: drying the high-temperature dyed fabric at a temperature of 110-150°C, and then drying The dried fabric is baked at 180-200°C for 1-5 minutes to form a graphene-based antibacterial fabric. The graphene-based antibacterial fabric preparation method of the present invention has a simple process and is easy to operate, and the prepared textile fabric has excellent antibacterial, anti-ultraviolet functions and instant cool feeling performance.

Description

technical field [0001] The invention belongs to the technical field of textile manufacturing, and relates to a textile fabric processing technology with protective function, in particular to a graphene-based antibacterial fabric preparation method. Background technique [0002] As people's requirements for environmental sanitation are increasing day by day, the application of antibacterial materials has received more and more attention. Bacteria will grow and reproduce rapidly under suitable environmental conditions, and spread diseases through contact with human bodies, affecting people's health. Textile fabrics composed of fibers, because of their porous shape and chemical structure of polymers, are conducive to the attachment of microorganisms, and become good parasites for the survival and reproduction of microorganisms such as bacteria and fungi. The textiles that people come into contact with in daily life are a good living place for these microorganisms and an import...
