Embodiment 1

[0041] A method for preparing antibacterial fabrics based on graphene includes four procedures of fabric pretreatment, dye solution preparation, high-temperature dyeing, and drying and baking. The specific process is:

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

[0043] Dye preparation: 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), stir and mix thoroughly A dye solution with a graphene oxide content of 0.05 g / L, a buffer content of 0.20 g / L, and a BB emulsion content of 0.30 g / L was obtained, ...

[0047] A method for preparing antibacterial fabrics based on graphene includes four procedures of fabric pretreatment, dye solution preparation, high-temperature dyeing, and drying and baking. The specific process is:

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

[0049] Dye preparation: add sodium acetate-acetic acid buffer and BB emulsion (wherein, the mass ratio of benzyl benzoate and castor oil polyoxyethylene ether is 2:3), stir and mix well to obtain a graphene oxide content of 0.10g / L. A dye solution with a buffer content of 0.30g / L and a BB emulsion content of 0.40g / L has a pH of 4.2.

Abstract

The invention provides a graphene-based antibacterial fabric preparation method which includes the steps: (1) fabric pretreatment: soaking a fabric by treatment liquid containing alkaline liquor and penetrating agents, and washing the fabric by water to reach neutral; (2) dyeing liquor preparation: diluting graphene oxide slurry by water, adding buffering solution and BB emulsion, uniformly mixingmixture to obtain dyeing liquor; (3) high-temperature dyeing: dyeing the fabric at high temperature by a temperature programming method according to a certain bath ratio; (4) drying and baking: drying the dyed fabric at the temperature of 110-150 DEG C, baking the dried fabric for 1-5 minutes at the temperature of 180-200 DEG C to obtain the antibacterial fabric based on the graphene. The BB emulsion is mixed emulsion of benzyl benzoate and polyoxyethylene castor oil. The antibacterial fabric preparation method based on the graphene is simple in process, easy to operate, the prepared textilefabric has excellent antibacterial and ultraviolet-proof functions, and a user instantly feels cool when contacting with the fabric.

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 hygiene are increasing, the application of antibacterial materials has received more extensive attention. Bacteria will grow and reproduce rapidly under suitable environmental conditions, and spread diseases through contact with the human body, affecting people's health. Textile fabrics composed of fibers, due to its porous object shape and high molecular polymer chemical structure, are conducive to the attachment of microorganisms, and become good parasites for the survival and reproduction of bacteria, fungi and other microorganisms. The textiles that people come into contact with in daily life are a good place for these microorganisms to survive and are also a...
