In addition, animal fibers such as wool, silk, cashmere, angora and the like carrying such an iodine antibacterial agent are knitted using a known knitting machine without using a special knitting device. It can be easily knitted into the desired product.
Therefore, when a fiber knitted mask knitted and knitted with animal fibers such as wool, silk, cashmere, and Angola carrying such an iodine antibacterial agent is attached to the human face, it enters and exits through the fiber knitted mask body. Antibacterial agents that are harmful to the human body, such as viruses and bacteria, are sterilized, the growth of bacteria is suppressed, or the activity of the bacteria is weakened to suppress the inhalation of pathogens. In addition, a fiber knitted mask having the effect of suppressing and preventing scattering of pathogenic bacteria can be obtained. In addition, a fiber knitted mask that retains antibacterial properties that can be worn for a long time can be obtained without releasing the antibacterial agent carried on the fiber by saliva, breath, or other substances emitted from the mouth or nose. Furthermore, the antibacterial property is maintained without releasing the antibacterial agent carried by washing, and a fiber knitted mask that can be used repeatedly by washing is obtained. In particular, a fiber knitted mask having a remarkably excellent effect can be obtained.

(W) The fiber according to claim 23 contains both the antibacterial fiber according to claims 12 to 21 and a non-antibacterial fiber that does not carry an antibacterial agent. The antibacterial fiber is at least one non-antibacterial selected from the group consisting of wool, silk, cashmere, Angola, cotton, hemp, linen, polyester fiber, polyamide fiber, polyacrylic fiber, polyurethane fiber, vinylon, and polyolefin fiber The following functions and effects can be obtained by a structure which is a fiber and is formed by knitting and knitting the antibacterial fiber and the antibacterial fiber in a mixed state.
The antibacterial fiber carrying the antibacterial agent has the effects described in the above (m) to (v), which are specific to the antibacterial fiber, and have physical properties specific to the antibacterial fiber. Therefore, the physical properties of the knitted mask depend on the physical properties of the antibacterial fibers to be used. Thus, an effect of widening the design range of the fiber knitted mask can be obtained.

In addition, in FIG.1 (b), the boundary of the said solid formation fiber knitting part and the said contact formation fiber knitting part is shown by a thin dotted line.

  In the fiber knitting mask main body 2, a three-dimensionally formed fiber knitting portion 21 is formed by knitting so as to form a breathing three-dimensional space in a portion that covers and wears the nostril and mouth of the human body when worn on the human body face. When worn on the face of a human body, the phenomenon that the three-dimensionally formed fiber knitting portion 21 is in close contact with the nostril or mouth and is prevented from breathing is suppressed, and it is easy and comfortable without feeling uncomfortable through the three-dimensional breathing space. Breathing is possible. The contact forming fiber knitting portion 22 is knitted so as to form a contact so as not to form a gap with the human body face. When worn on the human face, it is possible to prevent the passage of outside air through the gap between the face and the mask. Therefore, when breathing through the nostril or mouth, breathing and breathing air during breathing pass through the three-dimensionally formed fiber knitting portion 21 of the fiber knitted mask body 2 without leaking from the gap between the face and the mask. Is possible. As a result, inhalation of pollen, dust, virus, bacteria, mold, bacteria, and the like can be prevented, and the release and release of saliva, viruses, bacteria, and the like of the mask wearer can be prevented.

The fiber knitted mask body 1 is formed by knitting fibers. By selecting the fiber type, knitting method, knitting shape, etc., the three-dimensionally formed fiber knitted portion 21 and the close-contact formed fiber knitted portion 22 having desired properties such as shape, physical properties, stretchability, and other properties were designed and configured. The fiber knitting mask 1 is easily obtained. The fiber knitted mask body 2 having such desired properties can be easily mass-produced using a fiber knitting machine, and a fiber knitted mask that can be supplied to the market at low cost by mass production is obtained.

Chemical fibers include polyester fiber, polyamide fiber, polyacrylic fiber, polyurethane fiber, vinylon, polyolefin fiber, acetate fiber, rayon fiber, tencel fiber, polyvinyl chloride fiber, regenerated protein fiber such as milk and soybean, and other artificial fibers Fibers synthesized or regenerated can be used.
As a form of the fiber to be used, continuous fibers formed by gathering predetermined fiber raw materials in a desired thickness are used. The knitting method is not particularly limited, and any knitting method can be applied. For example, warp knitting or weft knitting is applied, and flat knitting machines, circular knitting machines, other known knitting machines, and the like are used. Further, flat knitting machines, rubber knitting machines, double-sided knitting machines, double-headed knitting machines, etc. classified into any of these knitting machines are used. As a form of the knitted and knitted mask, a fiber knitted mask having a predetermined mesh size, a mesh shape, a stretchable rubber form having a predetermined degree of expansion and contraction, and the like can be applied.

  The shape of the fiber knitted mask body 2 is not particularly limited, and an arbitrary shape such as a substantially square shape, an ellipse shape, or a polygon shape can be applied.

In this shape, as shown in FIG. 1 (b), when worn on the face of the human body, the three-dimensionally formed fiber knitted portion 21 is located at a position covering the nostril and mouth, and in the vicinity of the boundary between the nose and the eyes. The upper region of the contact forming fiber knitting part 22 is located, the lower region of the contact forming fiber knitting part 22 is located near the lower side of the mouth, and the both side regions of the contact forming fiber knitting part 22 are located at the position of the cheek of the face. . That is, a three-dimensionally formed fiber knitted portion 21 that forms a three-dimensional shape that can easily breathe is formed at a position that covers the nose and mouth, and a close-contact formed fiber knitted portion 22 is formed in a peripheral region of the three-dimensionally formed fiber knitted portion 21. Then, the contact forming fiber knitting portion 22 is attached in close contact with the face and cheeks of the upper nose region, the lower mouth region, and the both side regions of the nostril.

  The pair of ear hooks 3 are configured to be connected to symmetrical positions on both sides of the fiber knitted mask body 2. The fiber knitting mask 1 is attached to the human face in a state where the pair of ear hooks 3 are hooked on the ears of the human body and the three-dimensional fiber knitting part 21 of the fiber knitting mask body 2 is in a position covering the nostrils. used. A configuration in which the ear hooking portion 3 is directly fixed to the fiber knitting mask main body 2 or a configuration in which the ear hooking portion 3 is connected to the fiber knitting mask main body 2 by a connecting member can be implemented. For example, in the case of a configuration in which these are directly fixed, a configuration in which they are knitted with predetermined fibers and fixedly connected to each other, a configuration in which they are fixedly connected to each other by using an adhesive, or the like can be used. In the case of a configuration in which a connecting member is used, the connecting member includes a connecting member configured to be detachable by having concavo-convex shapes and entangled with each other, and a connecting member configured to be detachable such as a button. Can be used.

  Since the fiber knitted mask body 2 has a structure knitted with fibers, even after being worn and used on the human body, the contaminants attached to the fiber knitted mask body 2 can be removed without being deformed or damaged by washing. A fiber knitted mask that can be used repeatedly by being removed by washing or the like and is economically and environmentally advantageous without being disposable is obtained.
