preparation example Construction

[0032] see figure 1 Shown, the invention provides a kind of preparation method of antibacterial antiviral nonwoven fabric, comprises the steps:

[0033] S1, polyester staple fiber pretreatment: low-temperature plasma pretreatment is performed on polyester staple fiber to obtain pretreated polyester staple fiber;

[0034] S2, preparation of the first polyester staple fiber: prepare a carbon quantum dot solution with a predetermined concentration, then add titanium dioxide nanosheets and stir evenly to obtain a hydrothermal solution, put the hydrothermal solution and the pretreated polyester staple fiber together into a hydrothermal reaction kettle, and the pretreated polyester staple fiber is completely submerged in the hydrothermal solution for hydrothermal reaction; after the reaction is finished, it is naturally cooled to room temperature, and the reacted polyester staple fiber is taken out and After washing and drying, the polyester staple fiber loaded with carbon quantum do...

Embodiment 1

[0046] A preparation method for an antibacterial and antiviral nonwoven fabric, comprising the steps of:

[0047] S1, polyester staple fiber pretreatment: the polyester staple fiber is treated with low-temperature plasma for 5 minutes in a room temperature air medium with a discharge power of 100W and a discharge voltage of 25Pa to obtain pretreated polyester staple fiber;

[0048] S2, preparation of the first polyester staple fiber: prepare 100 mL of carbon quantum dot solution with a concentration of 0.4 mg / mL, then add 0.7 g of two-dimensional titanium dioxide nanosheets and stir evenly to obtain a hydrothermal solution, and mix the hydrothermal solution with 50 g of the Put the pretreated polyester staple fibers together into a hydrothermal reaction kettle, and completely immerse the pretreated polyester staple fibers in the hydrothermal solution, and perform a hydrothermal reaction at 100° C. for 4 hours; the reaction ends After natural cooling to room temperature, the po...

Embodiment 2-4

[0066] The difference from Example 1 lies in that the parameter settings in the preparation process are different, and other steps are the same as in Example 1, and will not be repeated here.

[0067] Table 2 is the parameter setting of embodiment 1 to 4

[0068]

[0069] The antibacterial and antiviral performance test results of the antibacterial and antiviral non-woven fabric prepared by the above-mentioned embodiment are shown in the following table: (note: the tests are all carried out under ordinary light conditions)

[0070] Table 3 is the performance parameter data of embodiment 1 to 4

[0071]

[0072] As can be seen from Table 3, in the present invention, the loading of titanium dioxide nanosheets, the loading of nano zeolite of silver-copper and the mixing ratio of the first polyester staple fiber and the second polyester staple fiber will all affect the composite nonwoven fabric prepared by the present invention. Antibacterial and antiviral properties have a...

Abstract

The invention provides an antibacterial and antiviral non-woven fabric and a preparation method thereof. The antibacterial and antiviral non-woven fabric is formed by compounding first polyester staple fibers loaded by carbon quantum dots and titanium dioxide nanosheets and second polyester staple fibers loaded by silver-loaded and copper-loaded nano zeolite, wherein the mass ratio of the first polyester staple fibers to the second polyester staple fibers is (30-70%): (70-30%). The antibacterial and antiviral non-woven fabric is prepared by compounding and blending the first polyester staple fibers loaded by the carbon quantum dots and the titanium dioxide nanosheets and the second polyester staple fibers loaded by the silver-loaded and copper-loaded nano zeolite; and the advantages of thesilver ion and copper ion inorganic antibacterial and antiviral agent and the titanium dioxide photocatalytic antibacterial and antiviral agent are integrated, the excellent adsorption performance ofthe nano zeolite and the excellent water solubility and optical performance of the carbon quantum dots are combined, and the antibacterial and antiviral performance of the non-woven fabric is synergistically improved.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric preparation, in particular to an antibacterial and antiviral nonwoven fabric and a preparation method thereof. Background technique [0002] With the increasing rampant of harmful bacteria and highly pathogenic viruses, non-woven masks, protective clothing, protective caps and other protective products have become necessities for medical staff and ordinary uninfected people since the outbreak. Now, with the resumption of production and work by the whole people, the demand for non-woven protective products has further expanded. Moreover, there is a higher demand for the antibacterial and antiviral functional properties of non-woven protective products. [0003] In the prior art, the methods for antibacterial and antiviral functional treatment of non-woven substrates are mainly divided into two categories: one is to load metal ion antibacterial agents (such as copper, silver, zinc, etc.) or...
