Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. Also, the use of the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.

The following first describes the antibacterial cloth for mask according to an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 1, the antibacterial cloth for a mask according to an embodiment of the present invention includes an inner layer 1, a core layer 2, and an antibacterial layer 3 stacked in this order from the inside (i.e., the side that is in contact with a person in actual use) to the outside (the side that is outward in actual use).

Wherein, the inner layer 1 can be polyester spunlace mesh non-woven fabric. The polyester spunlace mesh non-woven fabric has hygroscopicity, so that the breathable and waterproof effects can be met, and the mask has good antifogging and waterproof performances while having the characteristics of comfort, breathability and durability. The polyester spunlace mesh non-woven fabric has good moisture absorption performance, excellent antistatic performance and good air permeability, and overcomes the defect that the common mask is easy to fog when in use, particularly when wearing glasses.

The core layer 2 may be a polypropylene meltblown nonwoven.

Further, the fiber fineness of the core layer 2 is preferably 2 to 3 μm, and the fiber fineness of the inner layer 1 and the antibacterial layer 3 is larger than that of the core layer 2. Therefore, the core layer 2 is composed of PP melt-blown non-woven fabrics, the pores among the fibers are small, the PP melt-blown non-woven fabrics are uniformly distributed, the fiber fineness is 2-3 mu m, the total porosity is high, the specific surface area is large, the contact area with ambient air flow is large, the PP melt-blown non-woven fabrics are filtering layers of the mask, and the PP melt-blown non-woven fabrics play a strong role in intercepting and retarding particles, so that high filtering efficiency is realized.

Next, the antibacterial layer 3 is described in detail.

The purpose of the antimicrobial layer 3 is to prevent contamination by bacteria and the like.

The antibacterial layer 3 according to the present novel embodiment includes a substrate 31 and a nano silver material coating layer 32 formed on the surface of the substrate 31.

Regarding the bactericidal effect of silver, the research of a plurality of institutions approved by the U.S. Environmental Protection Agency (EPA) and Food and Drug Administration (FDA) shows that silver ions not only have an obvious effect in killing microorganisms, but also have a unique effect in long-acting inhibition and killing of diseased cells, and do not affect the normal activity of the cells.

The ginseng has different valence bond expression forms with the bactericidal activity, and the silver with different valence has different bactericidal performance, and the capacities are as follows: ag (III) > Ag (II) > Ag (I) > Ag

Ag + redox potential (0.798V, 25 ℃ C.).

Ag2+ redox potential (1.987V, 25 ℃).

Ag3+ redox potential (2.5007V, 25 ℃).

The higher the reduction potential, the greater the biological potential energy, the more active during sterilization and the stronger the capability.

The silver ion is usually Ag +, if 3 electrons are lost, the silver ion becomes Ag3+, and the sterilization capability is improved by more than 50-200 times; the high valence silver ion is 300 to 17000 times more effective than metallic silver or silver salt, and more 60000 times more effective than alcohol.

When the silver ions with positive charges contact with the microbial cells with negative charges, Ag3+ can effectively puncture cell membranes according to coulomb attraction (mutual attraction of positive and negative charges), so that cell proteins are denatured and cannot breathe, metabolize and reproduce until the cells die, and the killing is completed.

However, Ag3+ is relatively unstable, and for this reason, the present invention uses a trivalent silver-chlorhexidine complex that is sprayed onto the substrate surface to form the nano-silver material coating 32. The thickness of the trivalent silver-chlorhexidine complex coating is 0.05-0.1mm according to the requirements of use scenes and the like.

According to the utility model discloses an antibiotic cloth for gauze mask can dispose nanometer silver material dispersion at first, sets up on 31 top layers of base member with its multiple methods such as through spraying, roller coat, flooding afterwards, forms nanometer silver material coating 32 on 31 top layers of base member after the drying.

As for the nano silver material dispersion liquid, for example, a nano silver material dispersion liquid can be prepared by dispersing a trivalent silver-chlorhexidine complex in water. The concentration of silver ions in the dispersion may be from 0.1 to 100ppm, or higher depending on the particular application.

Tests show that the comparison is carried out by using the antibacterial agents with the same concentration (50 ppm in all), and the sterilization efficiency is 20 times compared with chlorine dioxide and 1000 times compared with iodophor. Therefore, the antibacterial cloth for the mask has a strong sterilization effect.

Moreover, by using the trivalent silver-chlorhexidine complex with high stability and high bactericidal activity, the mask can also keep effective antibacterial effect for a long time after being prepared.

According to the utility model discloses antibiotic cloth for gauze mask can be used for preparing antibiotic gauze mask. Of course, the use is not limited to this, and for example, an antibacterial garment or the like may be made.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
