To prevent insects such as ticks and mold on the tatami mat, use insect-proof / antibacterial-treated paper coated with or impregnated with an insecticide or insect-proof / antibacterial agent in the tatami mat, or knead insect / antibacterial agents. A non-woven fabric made of processed synthetic fibers was used. Furthermore, in the carpet laid on the floor,
An underfelt for carpet underlay, which is a mixture of synthetic fibers mixed with insect repellents and antibacterial agents, has been used.

後には住宅住民への影響も無視できない問題があった。The felts and non-woven fabrics obtained by processing the synthetic fibers in which the above insect repellent / antibacterial agents are kneaded have some early insecticidal / repellent effects against bacteria / pests (tick), In terms of divergence and deterioration over time and physical destruction after construction, the repellent / growth suppressing function was not satisfactory for a long period of time. In addition, the price of synthetic fibers mixed with the above insect repellent / antibacterial agents is high, and those obtained by integrating insect repellent paper non-woven fabric with the felt of the base material also require secondary processing such as piercing and pasting. Therefore, the production cost is high. Furthermore, since insecticides are used in the processing of insect-proof processed paper and non-woven fabrics by each manufacturer, there is a problem that the human body of the worker is adversely affected during the processing work, and the effect on the housing residents cannot be ignored after the construction.
