以下に本発明を詳述する。The present invention is described in detail below.
はじめに、本発明に用いる金属繊維不織布、エクスパン
ドメタルおよび所定のメッシュの網体について説明す

ｍ、長さ１〜２０cmよりなる金属細片の総称をいう。The metal fiber refers to a metal fiber and has a cross section of any shape such as a triangle or a circle and an effective diameter of about 20 to 200 μ.
m is a general term for metal strips having a length of 1 to 20 cm.
金属繊維の製造方法は、１例をあげると、 線引きによる機械加工法 溶融金属から紡糸する方法 等がある。As an example of the method for producing the metal fiber, there are a machining method by drawing, a method of spinning from molten metal, and the like.

接すると金属繊維不織布とのからみ合いが良い。Expanded metal is usually called a lath net, and is a metal thin plate in which a large number of cuts are made, and the cuts are pulled in a substantially perpendicular direction to form a net. Expanded metal is not a thin metal wire braided like a metal mesh, so the cut cross section of the thin metal plate is twisted by the tensile force, which is not only perpendicular to the plane of the thin metal plate, but also twisted in parallel or oblique directions. Therefore, when the metal fiber non-woven fabric is pressed onto this, the entanglement with the metal fiber non-woven fabric is good.
