Description

  The present invention relates to a sanitary mask, and particularly fits to the face including the nose and mouth, has good breathability, and does not cause the moisture of exhaled breath to adhere to the glasses and become cloudy. The present invention relates to a sanitary mask having actions such as deodorization, virus and bacteria death, and decomposition of foreign matters such as pollen.

  Conventionally, a sanitary mask worn in the case of a cold or hay fever uses a fabric in which at least the mask body is woven with weft yarns and warp yarns that are not stretchable (or very small in stretchability). Therefore, there is a problem that there is no feeling that fits the face including the nose part and the mouth part, and it is difficult to be familiar with the face. In addition, it has a structure in which a thin fabric is folded and overlapped, and a predetermined portion is sewn to form a substantially rectangular mask main body, and ear straps are provided on both sides thereof. However, there is also a problem that the breath that exhales leaks between the face and the mask body, moisture adheres to the glasses and becomes cloudy, and obstructs the field of view.

  In addition, when the mask body is made of a cotton cloth, when the mask body contains a lot of moisture, there is a problem that the face is wet and the touch is poor, and the breathability is lowered and the breathing is difficult. In addition, since the mask body does not have a sterilizing action, a deodorizing action, or a chemical substance decomposing action, there is a problem that if a strong odor substance or a bad scientific substance is sucked into the human body, it is directly sucked into the body. For example, when cedar pollen is sucked through a mask, there is a problem that although it is small, it directly enters the nasal cavity and eyes and stimulates the mucous membrane.

  In order to solve the above-mentioned problem, as disclosed in Patent Document 1, the moisture-absorbing and extensible cloth is formed of a hygroscopic-extensible cloth material in which fibers are stretched by absorbing moisture and a gap between the fibers is enlarged. There is a sanitary mask in which fine particles of photocatalytic apatite are adhered substantially uniformly on the surface and inside of a material.

The sanitary mask described in Patent Document 1 is a humidity in which light energy such as sunlight or fluorescent lamp light reacts with fine particles of catalytic apatite, has a bactericidal effect and a deodorizing effect, and has an inactivating action for viruses such as influenza. And absorbs moisture and humidity, thereby having the effect of easy breathing without deterioration of air permeability. That is, the function of the sanitary mask is dramatically improved and the air permeability is greatly improved by the synergistic effect with the sterilizing effect of viruses and the like due to the humidity accumulated in the mask main body with breathing. is there.
JP 2005-177320 A JP2000-202052

  The sanitary mask disclosed in Patent Document 1 is said to be easy to breath without deterioration of air permeability even if moisture accumulates in the mask body, but when much moisture is accumulated in the mask body, There is still a problem that the face feels wet and feels bad, and because the fabric that makes up the mask body is not stretchable, there is a problem that it does not give a feel that fits the face, and ventilation is not sufficient In addition, the problem that the moisture of breath exhaled on the glasses adheres and the glasses become cloudy cannot be solved.

  The present invention has been made in view of the above points, and is excellent in fit to the face, has a good touch without giving a wet feel to the face even if it contains a lot of moisture, has good breathability and is easy to breathe, and An object of the present invention is to provide a sanitary mask capable of decomposing and detoxifying harmful substances or odorous substances that have entered the mask while staying in the mask.

  In order to solve the above-described problems, the present invention provides a knit knitted fabric made of fibers, and forms the knitted knitted fabric into a predetermined shape by folding a plurality of times, and sews a predetermined portion to form a mask main body on both sides of the mask main body. The sanitary mask is characterized in that an ear strap is provided. By configuring the mask body with a knitted knitted fabric in this way, the knitted knitted fabric has a high stretchability, and thus gives a feeling that is perfect for the face, that is, a feeling that fits the face. In addition, since the knitted fabric has a high porosity, it has good air permeability and does not give a feeling of breathing that is easy to breathe. Furthermore, the exhaled breath does not leak from between the mask and the face, moisture adheres to the glasses, the glasses become cloudy, and the view is not obstructed.

  In the sanitary mask according to the present invention, the fibers are polylactic acid fibers. Polylactic acid fibers, for example, Terramac (registered trademark, registration numbers 4287254, 4374080, 4810442) are fibers based on polylactic acid produced from corn as a raw material, and have the property of being hydrophilic and wettable and having a fast drying property. Have. The knitted knitted fabric knitted from yarn made of polylactic acid fiber has good stretchability and gives a dry feel to the skin even if it contains a lot of moisture, so the sanitary mask made of this knitted fabric of polylactic acid fiber Has a good touch, gives a feeling of fitting to the face, and has good ventilation.

  In the sanitary mask, the present invention is characterized in that at least the sanitary mask main body is subjected to photocatalytic processing, and fine particles of photocatalytic apatite are uniformly attached to the surface and inside of the knitted knitted fabric. Thus, by uniformly adhering fine particles of photocatalytic apatite to the surface and inside of the sanitary mask body knit knitted fabric, virus, cedar pollen, and a foul odor substance that entered the sanitary mask body knit knitted fabric, Hazardous substances, such as chemical substances that harm the human body, are decomposed and rendered harmless in the presence of light energy such as sunlight and fluorescent light while remaining in the voids in the knit fabric with high porosity. The

  In addition, since the knitted fabric has a high porosity, breathing breath can be kept in the sanitary mask body for a long time, and at the same time, a lot of moisture in the breath stays there. Improvement in virus sterilization performance can also be expected. Furthermore, a knitted knitted fabric made of polylactic acid fibers has a characteristic of high wettability (hydrophilicity), so that a lot of moisture is likely to adhere to the fibers. Therefore, further improvement in sterilization performance can be expected.

  In the sanitary mask, the present invention is characterized in that the sanitary mask main body is configured so that a replenishing sheet material having air permeability can be attached to or detached from the inside or the side surface. By making it possible to attach and detach the replenishing sheet material having air permeability, it is possible to adjust the function of removing the harmful substances and breathability (breathability). In addition, since the sanitary mask body is formed of a knitted knitted fabric, the refill sheet can be easily inserted with high stretchability.

  In the sanitary mask, the present invention is characterized in that the replenishing replenishing sheet material is a knitted knitted fabric in which yarns made of polylactic acid fibers are knitted.

  In the sanitary mask, the present invention is characterized in that the air-permeable sheet material is subjected to photocatalytic processing so that fine particles of photocatalytic apatite are uniformly attached to the surface and inside.

  In the sanitary mask, the present invention is characterized in that a part or all of the knitted knitted fabric is subjected to a plant dyeing process.

  For example, safflowers are said to have the effect that carthamin (red) contained in the flowers prevents rough skin and prevents coldness. In recent research, it is said that the coronary arteries are expanded to lower blood pressure and cholesterol levels, and it is widely used for the treatment of diseases of the circulatory system. It is expected that the sanitary mask can be contributed to the health of the mask wearer by applying safflower plant dyeing to part or all of the knitted knitted fabric of the sanitary mask.

  According to the first aspect of the present invention, since the sanitary mask body is composed of a knitted knitted fabric, the knitted knitted fabric has a high stretchability and gives a touch that fits the face, and the knitted knitted fabric has a high porosity. Therefore, the breathability is good, the breathing is easy and the breathing feeling is not given at all. Furthermore, it is possible to provide a sanitary mask that has an excellent effect in that exhaled breath leaks between the mask and the face, moisture adheres to the glasses, becomes cloudy, and does not block the view.

  According to the second aspect of the present invention, since the fiber is a polylactic acid fiber, the knit knitted fabric obtained by knit-knitting the yarn made of the polylactic acid fiber has good stretchability, and even if it contains a lot of moisture, it is exposed to the skin. Therefore, it is possible to provide a sanitary mask that fits on the face and has good touch on the face.

  According to the third aspect of the present invention, at least the sanitary mask body is subjected to photocatalytic processing, and the photocatalytic apatite fine particles are uniformly attached to the surface and inside of the knitted knitted fabric. Hazardous substances such as viruses, cedar pollen, odorous substances, and chemicals that cause harm to the human body while entering the inside of the knitted fabric with high porosity remain in the gaps in sunlight or fluorescent light. It is decomposed and rendered harmless in the presence of light energy.

  According to the fourth aspect of the present invention, the sanitary mask main body can be detachably attached with a replenishment sheet material having air permeability on the inside or on the side surface, so that the function of removing harmful substances can be adjusted. Become.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing an external configuration of a sanitary mask according to the present invention, FIG. 1 (a) is a plan view, and FIG. 1 (b) is a side view. The sanitary mask 10 has a configuration in which a mask main body 11 and ear hook strings (usually rubber strings) 12 are provided on both sides. The mask body 11 folds a knitted knitted fabric 13 knitted with a yarn made of fibers a plurality of times, forms a rectangular shape in which a plurality of the knitted knitted fabrics 13 overlap each other, and forms sewing portions 14 near both side ends thereof. It is the structure which formed the ear hook string through-hole 15 in both sides.

  Although the fiber which comprises the thread | yarn for making the said knit knitted fabric 13 may be cotton, a chemical fiber, etc., the polylactic acid fiber is used here. As the polylactic acid fiber, for example, Terramac (registered trademark, registration numbers 4287254, 4374080, 4810442) manufactured by Unitika Co., Ltd. is used. Polylactic acid fiber is a biomass material composed of a plant-derived polymer, and the base polylactic acid is said to be produced from corn that is harvested in large quantities every year. Polylactic acid fibers are said to be decomposed (biodegraded) by microorganisms in the soil and eventually completely decomposed into carbon dioxide and water. Therefore, the mask main body 11 made of polylactic acid fiber is decomposed (biodegraded) by microorganisms by being placed in compost or soil after use, and finally completely decomposed into carbon dioxide gas and water.

  Polylactic acid fibers have the property of good wettability and quick drying. Therefore, the knitted knitted fabric 13 obtained by knitting the yarn composed of the polylactic acid fiber as described above has a good stretchability (this is a characteristic of the knitted knitted fabric itself), and further gives a silky feel (this is Features of polylactic acid fiber). Therefore, the sanitary mask 10 made of the knitted knitted fabric 13 made of polylactic acid fibers gives a feeling (a perfect feeling) fitted to the mask body 11. Further, since the porosity of the knitted knitted fabric 13 is larger than that of a normal warp and weft fabric, the air permeability is excellent and breathing is facilitated.

  Further, since the knitted knitted fabric 13 has good air permeability, air containing moisture exhaled by breathing goes out to the outside through a gap inside the mask body 11, so that the mask and the mask like a conventional sanitary mask can be used. There is no problem that breath exhaling through the gap between the faces leaks, moisture adheres to the glasses, and the glasses become cloudy.

The sanitary mask 10 having the above-described configuration is immersed in a photocatalyst processing liquid and dried, so that fine particles of photocatalytic apatite uniformly adhere to the surface and inside of the knitted knitted fabric 13 constituting the mask main body 11. Since the photocatalytic apatite represented by titanium oxide (TiO ₂ ) has hydrophilicity, the surface of the knitted knitted fabric 13 and the sanitary mask 10 are dipped or coated in a photocatalyst processing liquid and dried as described above. The photocatalytic apatite is uniformly and densely attached inside.

  Photocatalytic apatite is a place where light energy from the sun and fluorescent lamps is present, and a catalytic reaction takes place, decomposing and detoxifying foreign substances such as viruses, bacteria and pollen floating in the air, odors and chemicals harmful to the human body. Has the property of In particular, in the sanitary mask in which the mask body 11 is composed of a knitted knitted fabric 13, foreign substances such as viruses, bacteria, pollen, bad odors and harmful chemical substances in the knitted knitted fabric 13 are Will stay. And while it stays, it reacts with light energy, such as sunlight and fluorescent lamp light, and these can be decompose | disassembled efficiently and detoxified. As the photocatalyst processing liquid, for example, a photocatalytic processing liquid manufactured by Gaia Co., Ltd. is used.

  When photocatalyst processing is performed by dipping and drying in the photocatalyst processing liquid manufactured by Gaia Co., Ltd., the antibacterial action, the deodorization effect of ammonia, and the deodorization effect of trimethylamine are published in the company's pamphlet etc. In addition, the sanitary mask according to the present invention can be expected to have an antibacterial action and a deodorizing effect in a place where the light energy of sunlight or fluorescent light is present. In addition, it is disclosed that cedar pollen is also decomposed by the photocatalyst, and the cedar pollen can be expected to be decomposed even in the sanitary mask according to the present invention.

  In addition, a part or all of the knit knitted fabric 13 of the mask body 11 is subjected to a plant dyeing process. Unlike ordinary dyeing, the plant dyeing can be dyed at a low temperature, so that various kinds of plant dyeing can be performed without damaging the polylactic acid fiber that is weak at high temperatures constituting the knitted knitted fabric 13. For example, by applying safflower plant dyeing, it is expected to contribute to the health of the wearer of the sanitary mask 10 as described above.

  In the embodiment, as shown in FIG. 1, the knitted knitted fabric 13 is folded a plurality of times, the sewing portions 14 are formed in the vicinity of both side ends, the ear hook string through holes 15 are formed on both sides, and the ear hook string through holes are formed. 15, the sanitary mask having a configuration in which the ear strap 12 is penetrated has been described as an example. However, the sanitary mask according to the present invention is not limited to this configuration. For example, as shown in FIG. A pocket 21 for inserting a breathable replenishment sheet 20 may be provided in the mask body 11 made of the knitted fabric 13, and the replenishment sheet 20 may be inserted into the pocket 21. In this case, since the mask main body 11 is composed of the knit knitted fabric 13 having high elasticity, the inside of the pocket 21 can be enlarged when the replenishment sheet 20 is inserted, so that the replenishment sheet 20 can be inserted very easily.

  The material constituting the replenishment sheet 20 may be any material as long as it is air permeable and has a function of capturing foreign substances such as viruses, bacteria, and pollen in the outside air to be sucked. For example, in the case of a knit knitted fabric in which yarns made of polylactic acid fibers are knitted as described above, the replenishment sheet 20 itself also has elasticity, so that a fit feeling can be obtained when worn. The replenishment sheet 20 may also be immersed in the photocatalyst processing liquid and dried to uniformly adhere the photocatalytic apatite fine particles to the surface and inside thereof. A plurality of replenishing sheets 20 having different thicknesses may be prepared, and the difficulty of breathing may be adjusted by adjusting the trapping rate and air permeability of the foreign matter. Further, the number of supplementary sheets 20 to be inserted may be adjusted.

  The replenishment sheet 20 may be configured to be detachable on the outer side or the inner side of the mask body 11 by mounting means (not shown) (for example, Velcro (registered trademark, registration number 1328163)).

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible.

It is a figure which shows the structural example of the sanitary mask which concerns on this invention. It is a figure which shows the other structural example of the sanitary mask which concerns on this invention.
