In this way, on the one hand, when the protective clothing is discarded, it is easy to cause environmental pollution due to the slow degradation of disposable materials; on the other hand, reusable protective clothing needs to be washed, high-temperature disinfection and other measures before it can be reused, which also makes its protective performance usually poor. The washing and disinfection process will also increase a lot of labor costs and waste water resources
[0003] The existing technology has the following defects: traditional medical protective clothing itself cannot actively antibacterial and antiviral, and the antibacterial time is relatively short

Embodiment 1
[0023] A preparation method for a textile of medical protective clothing, comprising the following steps:
[0024] 1) Prepare nano-silver sol, nano-titanium dioxide, quaternary ammonium salt, and halogenated amine into a sol mixture of a certain concentration; the average particle diameter of the nano-silver sol is 25nm.
[0025] In the sol mixture, the molar concentrations of nano-silver sol, nano-titanium dioxide, quaternary ammonium salt, and halogenated amine are respectively: 1.8 mol / L, 1.2 mol / L, and 0.6 mol / L. The solvent is water.
[0026] 2) Soak the polypropylene spunbond nonwoven material in the above-mentioned sol mixture for 20 hours;
[0027] 3) The soaked polypropylene spunbond nonwoven material is dried at 110°C, flattened, and rolled to obtain an antibacterial and antiviral textile.
[0028] An active broad-spectrum durable antibacterial and antiviral medical protective clothing is made from the above-mentioned textile fabric as a fabric.
[0029] After was...
Embodiment 2
[0038] This embodiment is the same as Example 1, except that in the sol mixed solution described in this embodiment, the molar concentrations of nano-silver sol, bismuth tungstate, and chitosan are respectively: 2mol / L, 1.3mol / L, 0.8mol / L. The nonwoven material was soaked in the above-mentioned sol mixture for 10 hours.
[0039] An active broad-spectrum durable antibacterial and antiviral medical protective clothing is made from the above-mentioned textile fabric as a fabric.
Embodiment 3
[0041] This example is the same as Example 1, except that in the sol mixture described in this example, the molar concentrations of nano-silver sol, tungsten oxide, and deacetylated chitin are respectively: 2.3mol / L, 1.5mol / L , 1.0mol / L. Soak the non-woven material in the above-mentioned sol mixture for 1 hour.
[0042] An active broad-spectrum durable antibacterial and antiviral medical protective clothing is made from the above-mentioned textile fabric as a fabric.

Abstract
The invention discloses initiative broad-spectrum lasting antibacterial and antiviral medical protective clothing, textile fabric and a preparation method thereof. The preparation method of the textile fabric includes the steps that nano-silver colloidal sol, an inorganic antibacterial agent and an organic antibacterial agent are matched into colloidal sol mixed liquor of a certain concentration;non-woven materials are dipped into the colloidal sol mixed liquor for a certain time; and the antibacterial and antiviral textile fabric can be obtained by means of drying, flattening and winding. The initiative broad-spectrum lasting antibacterial and antiviral medical protective clothing is made of the textile fabric prepared through the method. A traditional metal ion antibacterial and antiviral technology, an organic matter antibacterial and antiviral technology and a photocatalyst antibacterial technology are combined, the lasting and effective broad-spectrum antibacterial and antiviralproperties are given to the medical protective clothing while breathability is not influenced, and the antibacterial rate reaches 99% or above; and moreover, the fast killing effect on influenza viruses (H1N1 and H3N2) is good, the antiviral activity rate reaches 99% or above, and washing reutilization can be achieved.
Description
technical field [0001] The invention belongs to the technical field of epidemic prevention equipment, and in particular relates to an active broad-spectrum durable antibacterial and antiviral medical protective clothing, a textile and a preparation method thereof. Background technique [0002] At present, the medical protective clothing on the market itself cannot disinfect viruses, bacteria, etc., mainly through the production standards of the protective clothing itself, on the one hand, the penetration of water, blood, alcohol and other liquids, to avoid the patient's blood during the operation. , body fluids and other secretions will transmit the bacteria and viruses carried to medical staff to prevent cross-infection between doctors and patients caused by the carried viruses; it can also block particulate matter to prevent viruses that spread through the air in the form of aerosols. Inhaled or attached to the skin surface to be absorbed by the body. In this way, on the on...
