なる。The nasal filter of the present invention is obtained by a nonwoven fabric molding method. This molding method is shown in FIG. That is, the nonwoven fabric 5 formed of undrawn fibers is sandwiched between the concave mold 6 and the convex mold 7 (FIG. 6A), and compression-molded while applying heat of, for example, 100 to 200 ° C. (FIG. 6A). 6 (b)). Thus, the nasal filter 1 of the present invention is obtained (FIG. 6C). The fibers forming the nonwoven fabric sheet are oriented and stretched by compressive deformation, so that the strength of the side wall particularly increases. In addition, since the degree of deformation increases near the top, the inter-fiber distance increases, resulting in a rough structure.

2 is preferred. The thickness is 0.5 mm or less, preferably 0.1 mm.
It is preferably from 2 to 0.4 mm. If the basis weight is small even if the thickness of the nonwoven fabric is 0.5 mm or less, the basis weight is reduced at the time of molding, the grain becomes coarse, the strength is reduced, and the nonwoven fabric cannot be used. For this reason, it is necessary to determine the thickness of the nonwoven fabric in relation to the basis weight in the above range.

汁を吸収し鼻汁による鼻孔の閉鎖を防止できる。The above-described nasal filter of the present invention has the following effects. (1) Dragging the nose hairs to the side of the nostrils reduces the resistance due to suction and facilitates breathing. (2) By making the filter diameter slightly larger than the nostril diameter, the nostrils widen and breathing becomes easier. Since the filter side wall is dense and the fibers are oriented and stretched, it has strength and is hard to be crushed. (3) By covering the inner wall of the nostril with a filter having a dense structure, it does not come into direct contact with allergic substances (pollen and the like). (4) When the filter is impregnated with a sustained-release drug, the inner wall of the nostril can be in direct contact with the drug for a long time, so that efficient treatment is possible. (5) If the filter is made of an absorbent material, it can absorb nasal secretions and prevent the nasal secretions from closing the nares.
