本発明は臭気吸着性と通気性を有するシート（−関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sheet having odor adsorption and air permeability.
カーボンに代表される臭気吸着剤はその吸着能を生かし
、臭気物質吸着剤として、冷威犀用等として日常使われ
ている。これは、吸着剤をそのまま使用するものである
が、プラスチックと混練し、シート化して吸着シー）と
して使用しようとする試みもある。Odor adsorbents such as carbon are used on a daily basis as odorous substance adsorbents, such as for cold rhinoceros, by taking advantage of their adsorption ability. In this method, the adsorbent is used as it is, but there is also an attempt to knead it with plastic and form it into a sheet for use as an adsorption sheet.
しかしながら、このような従来の吸着シートにあっては
、吸着剤が比較的厚いプラスチック層（ユ被覆されるこ
とにより十分効果を発揮できないという問題点があった
。However, such conventional adsorbent sheets have a problem in that the adsorbent is coated with a relatively thick plastic layer, which prevents it from being sufficiently effective.
本発明は、このような従来の問題点に着目してなされた
もので、通気性を有するシートに臭気吸着剤を保持させ

加しておけば、本発明の臭気吸着性シートが得られる。The present invention has been made by focusing on such conventional problems, and by making a breathable sheet hold an odor absorbent, it can uniformly and sufficiently absorb odor in any part of the sheet. The aim is to solve the above problems by making the system more effective. That is, the present invention makes it possible for one side of the sheet (= even if there is an odorous substance, no odor can be felt on the other side) while being breathable. In other words, the odor-absorbing sheet of the present invention is obtained by stretching a sheet-like material consisting of a thermoplastic resin, an inorganic filler, and an odor absorbent in at least one direction.By incorporating the inorganic filler into the thermoplastic resin and stretching it, it becomes a sheet. Micropores penetrate through it.If an odor adsorbent is added to this, the odor adsorbent sheet of the present invention can be obtained.
