Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a tatami structure with a deodorizing function.

(Prior art) As a means of giving tatami a deodorizing function for indoor air,
Activated carbon powder is sandwiched between two pieces of nonwoven fabric and integrated.
It is known to fix the obtained deodorizing sheet to the upper surface of a tatami floor by sewing, or to similarly fix a deodorizing sheet made of activated carbon fiber to the upper surface of a tatami floor.

(Problems to be solved by the invention) In conventional deodorizing tatami mats, a fiber sheet such as a deodorizing nonwoven fabric is first fixed to the tatami floor by sewing, that is, attached to the floor, and then the tatami face is attached to the tatami floor. It is fixed by sewing along the stile and side edges, so in order to replace the deodorizing non-woven fabric etc. when changing the tatami mat, it is necessary to remove the sewing threads that fix the tatami face to the tatami floor. It is necessary to cut and remove the tatami facing, and then further cut the sewing threads fixing the deodorizing nonwoven fabric, etc., to remove the deodorizing nonwoven fabric, etc., which makes it difficult to attach and remove the deodorizing nonwoven fabric, etc. Furthermore, conventionally, activated carbon powder or fibers have been used, resulting in poor sustainability of the effect.

This invention provides a tatami mat whose deodorizing sheet can be easily replaced when changing the tatami mat, and which has an excellent long-lasting deodorizing effect.

(Means for solving the problem) A deodorizing sheet 5 made by impregnating a non-woven sheet such as paper or non-woven fabric with a deodorizing agent containing ferrous sulfate and ascorbic acid as main components is applied to the tatami floor 4 and the tatami facing 6. The deodorizing sheet is then sewn and fixed to the stile and side edges of the tatami floor together with the tatami facing.

(Function) Since the deodorizer whose main components are ferrous sulfate and ascorbic acid chemically selects and deodorizes only bad odors, a deodorizing sheet 5 made by impregnating paper with an aqueous solution of the deodorizing agent is attached to the tatami. When used, the deodorizing effect of indoor air lasts for a long time, leaving behind the fragrance of flowers and removing only sweat and other bad odors. The deodorizing sheet 5 is not sewn to the tatami floor 4 alone, but is fixed to the tatami floor 4 when the tatami mat 6 is normally sewn, so when the tatami mat 6 is removed when replacing the tatami mat 6, etc. At the same time, it is separated from the tatami floor 4.

(Example) As shown in the drawing, insect repellent paper 2 is layered on both the upper and lower surfaces of straw bales 1, decorative insect repellents 3 are layered on top of the upper insect repellent paper 2, these are sewn together to form a tatami floor 4, and this tatami mat is floor 4
A deodorizing sheet 5 made of Japanese paper impregnated with a deodorizing agent (trade name "Anico") whose main ingredients are ferrous sulfate and ascorbic acid and a tatami mat 6 are stacked in order on the upper surface, that is, on the upper surface of the decorative mat 3. , the stile part was sewn by stile stitching, and the side edges were sewn by flat stitching. In an experiment using ammonia gas, the obtained tatami showed an initial deodorization rate 1.3 times higher than a comparative example in which activated carbon powder was sandwiched between two sheets of nonwoven fabric.
While the deodorization rate after 30 days decreased to about 40% of the initial rate in the comparative example, it hardly decreased in the example, demonstrating excellent deodorizing power and its sustainability, and using Japanese paper as the deodorizing sheet 5. Therefore, it has excellent hygroscopicity and water absorption, is soft and conforms well to the tatami floor 4, and does not impair the texture of the tatami. In addition, the tatami floor 4 is
It may also be made of insulation board, expanded polystyrene board, or the like.

(Effects of the invention) This invention uses a paper impregnated with a deodorizing agent whose main components are ferrous sulfate and ascorbic acid as a deodorizing sheet, so compared to the conventional one using activated carbon. It has an excellent deodorizing effect, is long-lasting, and can selectively deodorize only bad odors, leaving the fragrance in the room. In addition, the deodorizing sheet described above is not sewn directly to the tatami floor by itself, but is sewn together with the tatami mat cover and fixed to the tatami floor when the tatami mat cover is normally sewn, making it easy to attach and remove. , it can be easily replaced when changing the tatami mat.
