りそのかさばりが十分に解消されているとはいえない。Conventionally, knitted fabrics or nonwoven fabrics obtained by needle punching have been used as base fabrics for poultices. However, knitted fabrics are expensive, and the nonwoven fabrics obtained by the needle punching method are bulky and bulky when applied to the body. Therefore, recently, stretchable nonwoven fabrics have been developed as base fabrics for poultices, but the bulkiness of these fabrics has not yet been sufficiently eliminated.
これを解決するため、不織布の目付（坪量）を減少させ

服を汚染するなど、実用上支障をきたす欠点があった。In order to solve this problem, attempts have been made to reduce the basis weight of nonwoven fabrics, but in this case, the medicinal ingredients applied to the base fabric seep out to the opposite side of the applied surface, contaminating clothing, for example. There were some drawbacks that caused problems in practical use.

They discovered that by extrusion laminating nonwoven fabrics, it is possible to obtain poultice base fabrics that are not bulky, compact, fit well to the body, and do not ooze out medicinal ingredients.

が好んで用いられる。The thermoplastic synthetic resin used in the present invention includes polyester, polyamide, vinyl chloride, and polyolefin resins, among which various polyethylenes and modified polyethylenes such as ethylene-vinyl acetate copolymer are preferably used.
これらのフィルムの目付は２５ｇ／ｎ（未満が好ましい

However, if the nonwoven fabric according to the present invention is used, the film and the nonwoven fabric have sufficient adhesive strength,
Moreover, a soft base fabric can be obtained.

極めて好ましいことである。That is, in the present invention, among thermoplastic synthetic fibers such as polyester-based, polyamide-based or polyolefin-based synthetic fibers, particularly preferably polypropylene or polyethylene fibers containing 20% or more fibers with a basis weight of 10 g/rrf to 70 g/rrr, more preferably 15g/rd
A nonwoven fabric having a weight of 50 g/rrf to 50 g/rrf is used. Naturally, nonwoven fabrics with different specifications within the above-mentioned range may be used for the side to which the drug is applied and the opposite side. For example, blending 10% to 60% of non-thermoplastic and hygroscopic fibers such as vinylon, cotton, and rayon on the surface to which the drug is applied improves the drug's applicability and creates a soft base fabric. This is extremely preferable in terms of obtaining.

融点と同等かまたは大きく異ならない方が好ましい。Further, the proportion of thermoplastic synthetic fibers contained in the nonwoven fabric of the present invention is preferably 20% or more, but especially 4% or more.
0% or more is preferable. Furthermore, it is preferable that the melting point of any of the synthetic fibers contained in the nonwoven fabric be equal to or not significantly different from the melting point of the film to be laminated.

ので、身体へのフィツト性向上に有効である。The nonwoven fabric used in the present invention has a web prepared by a carding method, an airlay method, etc., and is further reinforced by heating, a water jet, a chemical binder, etc., but a nonwoven fabric containing composite fibers fused by heating is Particularly preferred. However, if the basis weight of the nonwoven fabric exceeds 70 g/n, the compact base fabric that is the object of the present invention cannot be obtained, and
If the basis weight is less than 1, it is difficult to manufacture. Furthermore, since the nonwoven fabric obtained by the carding method has good elongation in the lateral direction, it is effective in improving the fit to the body.
