Description
Technical Field
The invention belongs to the technical field of textile fabric processing, and particularly relates to an antibacterial ultraviolet-proof cotton fabric and a preparation method thereof.
Background
Pseudomonas aeruginosa is widely distributed in nature and is one of the most common bacteria existing in the environment, and a humid environment is an important condition for rapid propagation. Pseudomonas aeruginosa is a opportunistic pathogen that presents a greater health risk to people with weak resistance, even those with oral ulcers and oral trauma, who are at risk of purulent infection if water containing such bacteria is taken inadvertently. The pseudomonas aeruginosa has strong resistance to physicochemical factors and adverse environments, and the common disinfection means such as disinfectants, drying, ultraviolet rays and the like are not ideal for killing the pseudomonas aeruginosa.
The currently known antibacterial fabric has a good antibacterial effect on common staphylococcus aureus, escherichia coli and common fungi, but has a poor effect on pseudomonas aeruginosa.
In addition, the harm of ultraviolet radiation to human body is more and more important, and ultraviolet rays can cause sunburn and aging of human skin, generate melanin and color spots, and even more seriously induce canceration of human body. In the aspect of garment materials, ultraviolet rays can promote textile fading and embrittlement.
Disclosure of Invention
In view of this, the invention aims to provide an antibacterial ultraviolet-proof cotton fabric and a preparation method thereof, and the cotton fabric has excellent antibacterial effect and ultraviolet-proof performance.
In order to solve the technical problems, the invention provides a preparation method of an antibacterial ultraviolet-proof cotton fabric, which comprises the following steps:
s1, carrying out potassium carbonate water boiling on a cotton fabric, washing with water, drying, and treating with plasma;
s2, preparing finishing liquid: sequentially adding pterostilbene, concentrated ammonia water, a pyrylium salt photocatalyst and silver nitrate into methanol, and fully stirring to obtain a finishing liquid;
s3, soaking the cotton fabric processed in the step S1 in the finishing liquid obtained in the step S2 for padding, irradiating under ultraviolet light, washing and drying to obtain the antibacterial ultraviolet-proof cotton fabric.
Preferably, in the step S1, the concentration of the potassium carbonate is 20-50g/L, the dosage of the potassium carbonate solution is 8-10L per kilogram of cotton fabric, and the boiling time is 20-30 min.
Preferably, in step S1, the plasma processing conditions are: the gas adopts oxygen, the treatment power is 100-300W, the pressure is 50-60Pa, and the treatment time is 20-30 min.
Preferably, in step S2, the proportion of pterostilbene, concentrated ammonia water, pyrylium salt photocatalyst, silver nitrate and methanol is (0.6-1.2) g, (2-5) mL, (0.01-0.05) g, (0.1-0.8) g and 100 mL.
Preferably, in step S2, the pyrylium salt photocatalyst is one of 2,4, 6-triphenylpyrylium tetrafluoroborate, 2,4, 6-tris (4-fluorophenyl) pyrylium tetrafluoroborate, 2,4, 6-tris-p-tolylpyrylium tetrafluoroborate, and 2,4, 6-tris (4-methoxyphenyl) pyrylium tetrafluoroborate.
Preferably, in step S3, the bath ratio of the cotton fabric in the finishing liquid is 1:30-1: 50.
Preferably, in step S3, the padding is double-padding and double-rolling, and the rolling allowance is 80-90%.
Preferably, in step S3, the intensity of the ultraviolet light is 2400- 2 The irradiation time is 30-120 s.
Preferably, in step S3, the drying temperature is 100-120 ℃, and the drying time is 2-4 h.
The invention also provides the antibacterial ultraviolet-proof cotton fabric prepared by the method.
Compared with the prior art, the invention has the following beneficial effects:
the method adopts plant active ingredient pterostilbene as a reducing agent and a crosslinking monomer, leads the pterostilbene to reduce silver nitrate by a pyrylium salt photocatalyst under the irradiation of ultraviolet rays, further leads phenolic hydroxyl and double bond of the pterostilbene to be self-crosslinked and to be crosslinked with a pyrylium salt, and forms an ultraviolet absorption layer on the outer layer of the cotton fiber. The reduced silver ions are converted into nano silver particles which are coated and uniformly dispersed by the ultraviolet absorption layer. Finally, the pterostilbene-nano silver compound is formed, and the antibacterial effect of the fabric is enhanced. The uniformly dispersed nano silver particles also have the performance of reflecting ultraviolet rays, and the penetrability of the ultraviolet rays can be further reduced.
