そこで、近年、上記問題点を解決するために真空蒸着法
により金属被膜を付与する方法が試行されている。Conventionally, nonwoven fabrics with metal coatings have been used as electromagnetic shielding materials by lining FA and OA equipment, for example, because the metal coatings are conductive and the nonwoven fabrics are flexible. . Further, as another example, metal 'f11. Non-woven fabrics with membranes have large pores, have kunojin properties, and reflect heat rays due to the metal coating, so they can be used as overlays for kotatsu,
It was also used as a heat-insulating material for packages, trays, cabinets, etc. As a method for producing a nonwoven fabric having such a metal coating, there has been a method of electroless plating the nonwoven fabric with silver or the like. However, the electroless plating method consists of six steps: an alkali surface preparation step, a hydrochloric acid neutralization step, a catalyst application step, a catalyst activation step, an electroless agate wood step, and a drying step. Furthermore, each step is followed by washing with water. In addition, there are problems in that the number of steps is large and the cost is high, and the flexibility and cushioning properties of the nonwoven fabric are reduced because the nonwoven fabric is impregnated with an electrolyte. Therefore, in recent years, in order to solve the above-mentioned problems, attempts have been made to apply a metal coating using a vacuum evaporation method.
しかし、蒸着による方法は、不織布のほぼ平面上にしか
金属が積層されないため繊維の被渾着部面積が小さく、
しかも蒸着という性質上蒸着層を厚く形成するには限界
があり、充分な量の金属被膜が得られなかった。However, in the vapor deposition method, the metal is only layered on a substantially flat surface of the nonwoven fabric, so the area where the fibers are attached is small.
Moreover, due to the nature of vapor deposition, there is a limit to how thick a vapor deposited layer can be formed, and a sufficient amount of metal coating cannot be obtained.

させて単位体積当りの金属量を上げることもできる。In order to solve the above-mentioned problems, the present invention heat-treats a nonwoven fabric that exhibits bulkiness properties by heat-treating it to increase the bulkiness, and then vapor-deposit metal on at least one of the front and back surfaces. It was configured as follows. As for the type and size of the nonwoven fabric, any known nonwoven fabric can be used as long as it exhibits bulkiness when subjected to heat treatment. Such a nonwoven fabric is heat-treated to increase the bulk of the nonwoven fabric. The heating conditions may be set appropriately depending on the type of nonwoven fabric. Next, metal is deposited on the nonwoven fabric to form a metal coating. The type of metal may be selected depending on the use of the nonwoven fabric. For example, if excellent conductivity is required, aluminum, silver, copper, nickel, etc. may be used;
The metal coating may be formed in multiple layers by vapor depositing different types of metals multiple times, or the metal coating may be vapor deposited on both sides of the nonwoven fabric instead of only on one side. Further, after the vapor deposition, the nonwoven fabric can be further subjected to heat compression treatment to reduce the bulk thereof, thereby increasing the amount of metal per unit volume.

に形成される金属被膜の被覆面積が広くなる。When a nonwoven fabric that exhibits bulkiness is heat-treated, the nonwoven fabric increases in bulk and has voids several times the volume of the voids in the original nonwoven fabric, and each fiber constituting the nonwoven fabric increases in volume. The distance between them becomes wider. When metal is vapor-deposited on the non-woven fabric in this state, the vapor-deposited metal covers not only the surface layer of the non-woven fabric but also the internal fibers, increasing the coverage area of the metal coating formed on the fiber surface.

Thereafter, a heavy load of 200kg was applied at 220°C for 60m. The bulk of the nonwoven fabric was reduced by heat compression treatment at a speed of /win.As a result, the amount of metal per unit volume was increased by more than ten times compared to before heat compression treatment, while maintaining the flexibility and cushioning properties of the nonwoven fabric. A nonwoven fabric having a metal coating of approximately 100% was obtained.

特許出願人 日本写真印馴株式会社The method for manufacturing a nonwoven fabric having a metal coating according to the present invention is configured such that a nonwoven fabric exhibiting bulkiness by heat treatment is heat treated to increase the bulk, and then a metal is vapor-deposited on at least one of the front and back surfaces. has been done. Therefore, according to the present invention, the seventh metal covers not only the surface layer of the nonwoven fabric but also the internal fibers over a wide area, so there is a sufficient amount of metal coating, and the fibers are thinly coated, making it flexible. Nonwoven fabrics with excellent elasticity and cushioning properties can be easily produced. The thus obtained nonwoven fabric having a metal coating has a large amount of metal coating, has good conductivity, and is also excellent in flexibility, so it is suitable as an electromagnetic shielding material. In addition, the air gap is large (and has excellent cushioning properties), and the metal coating reflects heat rays, so it can be used as a heat insulating material.
It is also suitable as a heat insulating material. Patent applicant Nihon Shasha Inji Co., Ltd.
