In zeolite, zeolite, like feldspar, is a three-dimensional skeleton structure of (Si, Al) O 4 tetrahedrons by apical oxygen, but it has voids and contains water molecules and exchangeable cations. The water molecules are easily removed by heating at a relatively low temperature, but since the framework of the structure is not changed, the water molecules are absorbed in the air to fill the water. The chemical composition can be expressed as [Wy (Si, Al) (O 2 xnH 2 O)]. W is known to be Na and Ca, and K, Mg, Ba and Li.

The diatomaceous earth is mainly made of silicic acid (SiO 2 ), and since it is very porous, it is highly absorbent and is known to be used as an adsorbent, a filter material, a high-temperature material, an abrasive and the like.

As the environmentally friendly adhesive, Is preferably used. The high-weight zeolite powder or diatomaceous earth powder contained in the coating material thus prepared is improved in fluidity by the calcium carbonate, so that the sinking is significantly reduced in the reservoir and on the way from the reservoir to the nozzle such as the nozzle through the tube .

In the third step, the fabric may be any one of a paper fabric, a fiber fabric, and a nonwoven fabric. In the third step, about 5 to 300 g of coating agent per square meter of fabric, preferably about 20 to 60 g, Coating.
