Problems solved by technology

The sterilizing metal mesh used in this solution has a large mesh (0.00555 inches), which is much larger than the diameter of conventional droplets or aerosols. There is a high probability that droplets or aerosols will pass through directly without touching the sterilizing metal mesh. resulting in lower bactericidal efficiency
[0016] After retrieval and analysis, there is no safe and suitable method for manufacturing filter materials for antibacterial and disinfection masks in the existing schemes that are suitable for continuous and efficient industrial production

Embodiment 1

[0044] Embodiment one: as shown in Figure 1, the manufacture method of a kind of novel self-antibacterial disinfection mask filter material of the present invention comprises the following major steps:

[0045] (1) Power discharge, according to the tension information detected by the discharge tension adjustment roller, the speed of the discharge motor is controlled to achieve constant tension discharge and stable and constant speed production;

[0046] (2) Degreasing: use alkaline degreasing agent for cleaning, a preferred formula contains NaOH 150±100 g / L, NaOH 2 CO 3 30±20 g / L, Na 3 PO 4 30±20 g / L, alkylphenol polyoxyethylene ether 0.5±0.5 g / L, sodium lauryl sulfate or sodium lauryl sulfate 0.5±0.5 g / L, appropriate amount of defoamer, temperature controlled at 60±20℃;

[0047] (3) After degreasing, wash with water until the washing water is neutral, and multi-stage countercurrent washing can be used to improve efficiency;

[0048] (4) Pickling: neutralize the fiber su...

Embodiment 2

[0058] Embodiment 2: The difference from Embodiment 1 is that the activation process uses PdCl 2 The acidic solution is activated, and then add pure water washing process and clean the filter material until it is neutral, and then enter the pre-silver process as well. Other steps are all with embodiment one, wherein a kind of preferred palladium activation solution formula is: PdCl 2 0.15±0.1 g / L, concentrated HCl (37±3%) 25±10mL / L, control temperature at 30±20°C.

Embodiment 3

[0059] Embodiment 3: The difference from Embodiment 2 is that after the activation and washing process, the degumming process is added, and then the pre-silvering process is also entered, and other steps are the same as in Embodiment 1.

Abstract

The invention belongs to the technical field of daily protection products, in particular to a filter cloth material for a mask with self-antibacterial and self-disinfecting functions and a manufacturing method thereof. The specific implementation process comprises the steps of discharging, degreasing, washing, acid pickling, sensitizing, washing, activating, pre-silvering, silvering, washing, surface modifying, drying, collecting and the like, and proper nano-silver particles can be deposited on the fiber surface after a conventional mask filter material is treated by the method, so that the killing effect on microorganisms such as bacteria or viruses is realized. According to the technology, the defect that an existing mask filter material can only filter particulate matter or droplets but cannot exterminate bacteria or viruses can be overcome; meanwhile, the nano-silver particles and the filter material fibers are firmly combined and are only distributed on the surfaces of the filtermaterial fibers, and compared with other silver-containing filter materials, the nano-silver filter material has the advantages of continuous industrial production, high effective utilization rate ofsilver, strong binding force of the silver particles and the filter material fibers, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to a filter cloth material for masks with self-antibacterial and self-disinfection functions, and belongs to the technical field of daily protective articles. The self-antibacterial and self-sterilizing filter material is made by surface-treating the non-woven fabric or melt-blown fabric of the existing mask raw material, and then various mask products that can realize self-bacteria and disinfection can be made by the same method as ordinary masks. Background technique [0002] For microorganisms such as viruses or bacteria that are transmitted from person to person, the main transmission routes are droplet and aerosol transmission. The droplets sprayed by patients when they sneeze, cough or talk, and the droplets are mixed in the air. The formed aerosols are inhaled into the respiratory tract by contacts and lead to infection. Therefore, wearing a mask is a very necessary basic means of protection. Masks also play a key role in l...
