    As shown in the enlarged view of the structure of the nonwoven fabric in FIG. 1, the raw silk / silk nonwoven fabric fixed with gelatin according to the present invention is formed into a cloth shape in which the thin yarns of raw silk 2 or silk yarn 3 are intricately entangled in a random state. The nonwoven fabric 1 is formed.

  Since it is difficult to explain the details of the structure by the nonwoven fabric 1 having a structure in which thin yarns are entangled in a random state, the structural conceptual diagram of the nonwoven fabric by the raw yarn of FIG. 2 and the expansion of the nonwoven fabric by the silk yarn of FIG. This will be described in detail with the structure drawn simply by the structure conceptual diagram.

  In the conceptual diagram of the structure of the nonwoven fabric of raw silk in FIG. 2, after the raw silk 2 having a structure in which two fibroin 7 are surrounded by sericin 6 is fixed by the gelatin layer 4, the metal thin film layer 5 is formed on both surfaces by a vacuum deposition technique. Represents the concept of a coated structure.

  3 is a schematic diagram of the expanded structure of the nonwoven fabric made of silk thread in FIG. 3 and explains in more detail the concept of the nonwoven fabric 1 of the present invention made of silk thread 3 made only of fibroin 7 obtained by removing sericin 6 from raw silk 2 instead of raw silk 2 shown in FIG. To do.

  A gelatin layer 4 is fixed to each raw silk 2 or silk thread 3, and the gelatin layers 4 adhere to each other to form a cloth-like nonwoven fabric 1. Further, a metal thin film layer 5 is formed on one side or both sides of the nonwoven fabric 1. By coating, a non-woven fabric of raw silk and silk thread fixed with gelatin of the present invention is formed, and the non-woven fabric 1 of the present invention has a large proportion of gaps, so even if the metal thin film layer 5 is coated, there are many gaps and good air permeability. The nonwoven fabric 1 can be obtained.

    FIG. 4 is a structural diagram of raw silk. Briefly explaining the difference between raw silk 2 and silk thread 3, raw silk 2 is composed of two thin fibers, fibroin 7, which is covered with a substance called sericin 6 in a single fibrous form. This is called raw silk 2, which is in a state of being taken out from the cocoon.

  The sericin 6 is removed from the raw silk 2 and only the fiber of the fibroin 7 is called the silk thread 3.

  The structure of the non-woven fabric of raw silk and silk thread fixed with gelatin of the present invention is as described above. The manufacturing method will be described below.

  The raw silk 2 or silk thread 3 is entangled in a random state, and the gelatin layer 4 is fixed by a technique such as spraying or painting a gelatin solution formed on an approximately cloth-like shape, followed by natural drying.

  Thereafter, the non-woven fabric in which the gelatin layer 4 is dried is hot-pressed with a heat press device at a temperature of about 130 ° C. to increase the adhesion strength between the raw silk 2 or the silk thread 3 and the gelatin layer 4, and the raw silk 2 Alternatively, the non-woven fabric 1 is formed by bonding the gelatin layers 4 formed on the silk thread 3 together.

  A gold or silver metal thin film layer 5 is formed on one side or both sides of the nonwoven fabric 1 by a vacuum deposition method, and then hot pressing is performed again at a temperature of about 130 ° C. to thereby form the gold or silver metal thin film layer 5 and the nonwoven fabric 1. By stabilizing the adhesiveness to the fabric, a nonwoven fabric of raw silk and silk thread fixed with gelatin of the present invention can be obtained.

  The hot press apparatus shown in the conceptual diagram of the hot press in FIG. 5 is sandwiched between a hot plate table 20 containing a heater 22 and a hot plate 21 for press containing a heater 22, and has an appropriate temperature of about 130 ° C., for example. A more stable nonwoven fabric 1 can be obtained by applying a suitable pressure by pressing down the hot plate 21 for pressing by operating a lever of a hot press device while applying a temperature.

  When the nonwoven fabric 1 is sandwiched between the hot plate table 20 and the hot plate 21 for pressing in the above-described hot press device and an appropriate pressure is applied while applying an appropriate temperature of about 130 ° C., the nonwoven fabric 1 is pressed by the hot plate table 20 or the press. In order to prevent contact with the hot plate 21 and preventing the hot plate 21 from peeling off, a pressure such as a paper called a top paper 23 or an under paper 24 is applied between the nonwoven fabric 1 and the hot plate table 20 or the hot plate 21 for pressing. If manufactured, the nonwoven fabric 1 can be prevented from being peeled off and still produce good results.

  In the structure of the resistance heating type vacuum vapor deposition apparatus shown in the conceptual diagram of the vacuum vapor deposition machine in FIG. 6, a boat 31 made of tungsten or the like that also serves as a heater for heating the raw material is fixed to the lower part of the vacuum container 30. A nonwoven fabric 1 as a sample 32 on which a metal thin film layer 5 such as silver is vapor-deposited is fixed to the upper part.

  In order to form the gold or silver metal thin film layer 5 by this resistance heating type vacuum vapor deposition apparatus, the gold or silver metal 33 for the thin film layer weighed at a predetermined ratio was also used as a heater in the vacuum vessel 30. After being housed in the boat 31 and evacuated by the pump 34 so that the inside of the vacuum vessel 30 has a predetermined degree of vacuum, a predetermined current is passed through the boat 31 to gradually increase the temperature of the boat 31 that also serves as a heater. When the melting point temperature of the silver metal 33 is reached, the gold or silver metal 33 is dissolved and vaporized, and is deposited on the inside of the sample 32 which is the nonwoven fabric 1 and deposited.

  When the vapor deposition operation is completed, air is introduced into the vacuum vessel 30 and the nonwoven fabric 1 on which the gold or silver metal thin film layer 5 is formed is taken out of the vacuum vessel 30, so that the raw silk and silk yarn fixed with the gelatin of the present invention can be obtained. A nonwoven fabric can be obtained.

  FIG. 7 shows an example in which the nonwoven fabric 1 of the present invention is applied to a mask 8 as an application of a raw silk / silk nonwoven fabric fixed with gelatin according to the present invention.

  The mask 8 is used for the purpose of preventing harmful substances floating in the atmosphere such as pollen 11, viruses 12, and dust 13 that are harmful to the human body from being taken into the human body by breathing.

  The mask 8 is composed of two cloth-like outer materials 9 and an inner material 10, and is an example in which the nonwoven fabric 1 of the present invention is mounted between two outer and inner materials.

  Since the mask 8 has the above-described configuration, harmful substances such as pollen 11, virus 12, and dust 13 present in the atmosphere are reduced by the pollen 11 and dust 13 being absorbed to some extent by the outer material 9, thereby reducing the two materials. The antibacterial property of the non-woven fabric 1 mounted between the metal and the gold removes many pollen 11, virus 12, and dust 13 including virus 12, and further removes harmful substances remaining in the inner material 10. It is configured as follows.

  Thus, by applying to the mask 8 etc., it has the effect that the antibacterial property by the gold | metal | money and silver metal thin film layer 5 of the raw silk and silk nonwoven fabric fixed with the gelatin of this invention can be exhibited effectively. .

  As another application of the non-woven fabric 1 of the present invention, the gelatin layer 4 is water-soluble and has a property that it is particularly soluble in warm hot water. If placed in a container containing water or the like, the effect of being able to delay the decay of drinking water or the like due to the antibacterial action of the gold or silver metal thin film layer 5 of the nonwoven fabric 1 can be expected.

  As described above, if the raw silk / silk nonwoven fabric fixed with gelatin according to the present invention is used, it can be applied to various scenes where the antibacterial property of the metal thin film layer 5 made of gold or silver can be exhibited, and water-soluble gelatin. If the characteristics of the layer 4 are also used, an effective application in many scenes can be expected.
