FIG. 3 is an enlarged conceptual diagram of a portion indicated by a symbol A in FIG. 2. It is a conceptual diagram of the face mask which shape | molded the nonwoven fabric manufactured using the coating method which concerns on embodiment of this invention.

Below, the application | coating method to the nonwoven fabric of the magnesium hydride which concerns on embodiment of this invention is demonstrated, referring FIG. 1 thru | or FIG.
FIG. 1 is a process flow diagram of a coating method according to an embodiment of the present invention.
In FIG. 1, step S1 is a mixture preparation process of magnesium hydride and hydroxypropyl cellulose. As the cellulose-based adhesive, hydroxypropylcellulose, whose safety has been recognized in cosmetics and the like, was used. This is because, by mixing a cellulosic adhesive, it is possible to easily add adhesiveness to the nonwoven fabric. Since cellulose is a natural polymer and is used because of its high safety, hydroxypropylcellulose is used in this embodiment, but it is safe even if it adheres to human skin. The adhesive is not particularly limited to hydroxypropylcellulose as long as it is a system adhesive.
Magnesium hydride and hydroxypropyl cellulose are in powder form and can be easily mixed. The blending ratio (weight ratio) of magnesium hydride and hydroxypropyl cellulose is in the range of 1: 0.25 to 1: 2. When the blending of hydroxypropyl cellulose is lower than 1: 0.25, the viscosity is insufficient, and when the blending of hydroxypropyl cellulose is higher than 1: 2, the viscosity becomes too high and smooth application to the nonwoven fabric is hindered. At the same time, the concentration of magnesium hydride decreases, and a sufficient amount for the purpose of generating hydrogen cannot be applied.
In particular, the range of 1: 0.8 to 1: 1 is high enough that the viscosity of the preparation liquid is an appropriate range and at the same time the concentration of expensive magnesium hydride is not excessive and sufficient hydrogen generation can be expected. So desirable.

The mixture of magnesium hydride and hydroxypropyl cellulose prepared in step S1 is prepared by adding anhydrous ethyl alcohol in step S2. At that time, a stirrer is set in anhydrous ethyl alcohol, and a mixture of magnesium hydride and hydroxypropyl cellulose is added little by little while sieving with a net. When the mixture is contained in a spherical mass called “dama” in an undissolved state, it is stirred with a stirrer until the dama disappears in the preparation liquid.
In addition, since magnesium hydride reacts with water but does not react with ethyl alcohol, ethyl alcohol is selected as the solvent of the preparation liquid. Therefore, ethyl alcohol needs to be anhydrous.

Next, the application | coating process to the nonwoven fabric of a preparation liquid is performed as step S3. The application process will be described with reference to FIG. FIG. 2 is a conceptual diagram showing a configuration of a hydride coating apparatus for performing the coating of the preparation liquid on the nonwoven fabric.
In FIG. 2, an unwoven cloth (designated by reference numeral 2) is installed in the uppermost stream of the hydride coating apparatus 1. Examples of the nonwoven fabric 2 include, but are not limited to, a nonwoven fabric in which the blending ratio of rayon and pulp is 50% (weight ratio), respectively.
The non-woven fabric 2a is guided from the non-woven fabric 2 and the prepared liquid 7 stored in the bat 6 is applied at the gravure printing section indicated by the symbol A through the rollers 3a and 3b. FIG. 3 shows an enlarged view of the gravure printing portion indicated by the symbol A.

In FIG. 3, the non-woven fabric 2 a is a plate cylinder (plate cylinder) 4 that is immersed in the bat 6 and rotates in the direction of the symbol b, and a pressure that is arranged on the upper part without being immersed in the bat 6 and rotates in the direction of the symbol c. It is sandwiched between cylinders (pressure cylinders) 5 and moves in the direction indicated by symbol a so that pressure can be applied to the surface thereof. Then, the non-woven fabric 2 a is coated with the preparation liquid 7 adhered to the surface of the plate cylinder 4 when moving between the plate cylinder 4 and the impression cylinder 5.
The temperature of the preparation liquid 7 stored in the bat 6 is normal temperature (5 ° C. to 35 ° C.). This is because the solubility of the magnesium hydride and the cellulose-based adhesive and the viscosity of the preparation liquid at the time of application to the nonwoven fabric by the gravure cylinder are appropriately adjusted. Moreover, since the preparation liquid 7 of magnesium hydride and hydroxypropyl cellulose uses ethyl alcohol as a solvent, it prevents evaporation of ethyl alcohol and is dangerous if a heat source is placed near the vat 6.
Further, the doctor 11 is a member for scraping off the excess preparation liquid 7 adhering to the plate cylinder 4 so that the surface of the plate cylinder 4 is smoothed and the preparation liquid 7 is uniformly applied to the surface of the nonwoven fabric 2a. To be effective.

表１によれば、平成２６年５月３１日の実験開始時では、試作品段階ということもあって、０．１９−０．３４ｇ／ｍ^２程度であったものの、平成２７年２月２日、３日では０．６ｇ／ｍ^２、同年７月２２日では２．７ｇ／ｍ^２、同年１０月２２日では２．５ｇ／ｍ^２まで増加し、今年に入ってからの１月１２日では２ｇ／ｍ^２を維持しており、現状では、概ね１平方メートル当たり２ｇ程度の水素化マグネシウムの塗工量を維持している。
なお、この塗布後反１０における水素化マグネシウムとヒドロキシプロピルセルロースの含有重量比は図１に示したステップＳ１の水素化マグネシウムとヒドロキシプロピルセルロースの混合物作成工程における配合重量比と同一である。すなわち、エチルアルコールが蒸発した乾燥後も水素化マグネシウムとヒドロキシプロピルセルロースの配合比率は維持されている。 Returning to FIG. 1 and FIG. 2, the description will be continued.
Step S4 is a nonwoven fabric drying process. The nonwoven fabric is dried by a dryer 8 shown in FIG. The nonwoven fabric 2a to which the preparation liquid 7 is applied in the gravure printing section A is carried into a dryer 8 having a height of about 10 m via rollers 3c and 3d. Inside the dryer 8, a heater or a hot air blower is installed and controlled at around 60 ° C. The dryer 8 evaporates and dries the ethyl alcohol in the applied preparation liquid 7 while conveying the nonwoven fabric 2a in the vertical direction.
Since the nonwoven fabric 2a is transported at a constant speed, in order to sufficiently dry the inside of the dryer 8 while sufficiently applying the preparation liquid 7 in the gravure printing section A, magnesium hydride or hydroxypropyl of the preparation liquid 7 is used. Management of the concentration of cellulose is important.
An appropriate width considering that the nonwoven fabric 2a sufficiently dried in the dryer 8 is processed into a final product using the nonwoven fabric from the width of the nonwoven fabric raw material 2 by the cutter 9 via the rollers 3e to 3h. After being applied, the film is wound as an anti-coating (and swallow) 10 via the rollers 3i to 3k.
In the process as described above, the inventors conducted experiments on how much magnesium hydride can be applied to the nonwoven fabric 2a in a dry state. The experimental results are shown in Table 1. A numerical value is the coating amount of the magnesium hydride per square meter after the drying process of the nonwoven fabric of step S4.

According to Table 1, at the start of the experiment on May 31, 2014, it was about 0.19-0.34 g / m ² due to the fact that it was a prototype stage. day, three days ^{0.6g / m 2, 2.7g / m} 2 in the same year on July 22, increased to 2.5g / ^{m 2} in the same year on October 22, January since the beginning of the year 12 At 2 g / m ² on the day, the amount of magnesium hydride applied is approximately 2 g per square meter.
The content weight ratio of magnesium hydride and hydroxypropyl cellulose in the post-coating 10 is the same as the blending weight ratio in the step of preparing a mixture of magnesium hydride and hydroxypropyl cellulose in step S1 shown in FIG. That is, the blending ratio of magnesium hydride and hydroxypropyl cellulose is maintained even after drying after evaporation of ethyl alcohol.

Step S5 is a forming process of the nonwoven fabric 2a dried in the drying process.
The post-application post 10 shown in FIG. 2 has a reverse shape (roll shape), which is further appropriately shaped in accordance with the application and purpose.
For example, the conceptual diagram of the face mask which shape | molded the nonwoven fabric manufactured using the coating method which concerns on FIG. 4 at embodiment of this invention is shown.
The face mask 15 shown in FIG. 4 is formed in the shape of the entire face, and an eye hole 16 for projecting an eye when sticking on the face and a nose part are provided at the center. A nose slit 17 for the mouth and a mouth hole 18 for taking out the mouth portion are formed. In addition, the peripheral slit 19 is notched around the periphery so that various sizes of the face can be supported. This face mask 15 is formed by using a nonwoven fabric manufactured by using the method for applying magnesium hydride to a nonwoven fabric described with reference to FIGS. 1 to 3.
The face mask 15 is not particularly coated with an adhesive to be applied to the face. However, the face mask 15 is placed on the face, and water is sprayed thereon using, for example, an atomizer such as an atomizer. Then, since the face mask 15 is moistened to increase the adhesion to the face, there is no fear that the face mask 15 will fall off the face during use when lying down.

According to the face mask 15 according to the present embodiment, it can be easily carried with a dehumidifying agent such as silica gel, and hydrogen can be easily generated by spraying moisture on the face mask 15 as necessary. . Moreover, since it is applied uniformly and uniformly, hydrogen can be generated gently from the entire face mask 15. Further, hydroxypropyl cellulose to which magnesium hydride is bonded is a cellulose-based adhesive that has been used in cosmetics and has been confirmed to be safe, and can be used as a face mask 15 that is also friendly to human skin.
In this embodiment, the face mask 15 formed in the shape of the entire face is described. However, the face mask 15 is not limited to the entire face, and may be a part of the face. For example, a face mask formed on a partial surface imitating the periphery of the eyes may be used.

  The invention described in claims 1 to 6 of the present invention is used for manufacturing a non-woven fabric and a face mask in which magnesium hydride can be easily and safely carried.
