Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the inherent cytotoxicity that cannot be overcome by existing metal series antibacterial agents and organic compound antibacterial agents, and the inability to connect graphene oxide with fabrics, which is difficult to industrialize and other defects, and provides a new type of antibacterial Fabric and its preparation method, which rely on the purely physical severing action of the micro-nano structure of graphene oxide to kill bacteria

Embodiment 1

[0030] Embodiment 1 Modified polyethersulfone (PES) antibacterial fabric (fabric 1)

[0031] Put 5g of PES (weight-average molecular weight=410,000) fabric into deionized water and rinse 5 times. Immerse the rinsed PES fabric in an aqueous solution containing 0.5% (w / w) N, N'-methylene bisacrylamide for 24 hours until saturated adsorption; take out the fabric and use absorbent paper to absorb the surface solution and put it into negative pressure As a filter cloth in the filter, introduce 500 g of GO aqueous solution with a graphene oxide (GO) concentration of 0.1 mg / mL into the filter cup of the negative pressure filter, filter once at normal pressure, take out the fabric, and absorb the surface solution with absorbent paper Finally, it was placed in a cobalt source and irradiated to 1 kGy, then taken out, extracted with ethanol for 48 hours, and then vacuum-dried to constant weight to obtain an antibacterial fabric 1 containing GO, with a GO content of 1%.

Embodiment 1

[0033] Comparative example 1 blank polyethersulfone (PES) fabric (contrast 1)

[0034] The antibacterial performance and cytotoxicity of the PES fabric before modification in Example 1 were tested according to the method of Example 1, and the test results are shown in Table 1.

Embodiment 2

[0035] Embodiment 2 modified antibacterial cotton fabric (fabric 2)

[0036] 5 g of natural cotton fabric was rinsed 5 times in deionized water. Soak the rinsed cotton fabric in methanol solution containing 2.5% (w / w) triallyl cyanurate for 36 hours until saturated adsorption; take out the fabric and use absorbent paper to absorb the surface solution and put it into negative pressure filtration In the container as a filter cloth, introduce 250 g of GO aqueous solution with a graphene oxide (GO) concentration of 2 mg / mL into the filter cup of the negative pressure filter, vacuum filter 3 times, take out the cotton cloth, and absorb the surface solution with absorbent paper, Put it into the cobalt source and irradiate it to 35kGy, take it out, extract it with ethanol for 48 hours, and then vacuum dry it to constant weight to obtain the antibacterial fabric 2 containing GO, with a GO content of 1.8%.

[0037] The antibacterial fabric 2 was washed 50 times according to the ACCTCC...

Abstract

The invention relates to a type of antibacterial fabric and a preparing method thereof, with the preparing method comprising: adsorbing cross-linking agent to the surface of fabric containing C-H key to obtain the fabric adsorbing cross-linking agent; taking the fabric adsorbing cross-linking agent as filter cloth for filtering oxidation graphite alkene aqueous solution to obtain the fabric containing both the cross-linking agent and the oxidation graphite alkene; and employing radiation crosslinking method or heat crosslinking method to initiate the cross-linking agent upon the fabric containing both the cross-linking agent and the oxidation graphite alkene for crosslinking polymerization, thus to obtain antibacterial fabric, wherein the cross-linking agent contains more than two carbon-carbon double bonds and / or Carbon-carbon triple bonds. The method of the invention is easy to operate, consumes less amount of oxidation graphite alkene, uses less amount of time in post-treatment period, and is of low cost and suitable for large scale industrialized production. Moreover, the antibacterial fabric made in this way keeps great antibacterial performance even after repeated washing. With the cytotoxicity at Level 0 (the highest security level), the antibacterial fabric produces nearly no irritation to skin.

Description

technical field [0001] The invention relates to an antibacterial fabric and a preparation method thereof. Background technique [0002] With the gradual improvement of people's living standards, personal hygiene and health issues have been paid more and more attention. As a necessity of human life, fiber textiles have been paid more and more attention to their safety and hygiene functions. Under this social trend, the research on various antibacterial fabrics has developed rapidly in the past two decades. And since the 21st century, the successive outbreaks of major infectious diseases including SARS, bird flu, and H1N1 flu have once again threatened the safety of human life, and have also put forward more stringent requirements for public health. [0003] At present, the preparation methods of antibacterial fabrics can be roughly divided into two methods: physical modification and chemical modification. The physical method adds the antibacterial agent to the fabric fiber...
