ものである。The present invention is a non-woven fabric having an apparent density of 0.18 to 0.30 g / cm 3 composed of ultra-fine fibers having an average fiber diameter of 8 μm or less obtained by spinning with an ultra-fine fiber-forming spinning method, and one surface of the non-woven fabric is 100 % Modulus is 3kg / cm 2 or less is a surface where a binder resin is applied to form a layer in which fibers and a binder resin are mixed and which is embossed, and the other surface contains almost no binder resin. It is a characteristic sticking base material. That is, a non-woven fabric composed of ultrafine fibers having an average fiber diameter of 8 microns or less, which constitutes the sticking substrate of the present invention, is a fiber-forming polymer such as polyethylene terephthalate.
Polyester such as polybutylene terephthalate or hydrophilic and / or lipophilic polyester, 6-
Polyolefin such as polyamide such as nylon, 66-nylon, 12-nylon, polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-octene copolymer, or hydrophilic and / or lipophilic polyolefin, ethylene-vinyl acetate At least one polymer selected from saponified copolymers, polyurethane elastomers, polyester elastomers, polyvinyl alcohol, acrylonitrile-based polymers, etc. was obtained by spinning with an ultrafine fiber-forming spinning method such as melt blown spinning or flash spinning. Ultrafine fibers having an average fiber diameter of 8 microns or less, preferably ultrafine fibers having an average fiber diameter of 5 microns or less. The melt blown spinning method, which is one of the ultrafine fiber forming type spinning methods, spins the polymer at a spinning temperature of 250 to 300 ° C, and carries gas pressure (gauge pressure) of 0.5 to 5 kg / cm 2 , carrier gas temperature.
By spinning under conditions of 150 to 330 ° C, a good ultrafine fiber stream can be formed, and by collecting this fiber stream in a sheet form with a collector, a good ultrafine fiber nonwoven fabric can be obtained. it can. It is also preferable that this non-woven fabric is subjected to a pressing treatment as needed to densify at least one surface and to bond the fiber contact portion. If necessary, the ultrafine fiber nonwoven fabric may be made into a fiber entangled nonwoven fabric by a water jet treatment, a needle punching treatment, or the like. The weight of this ultrafine fiber non-woven fabric is determined by the intended use of the adhesive substrate, but the permeability of the drug into the non-woven fabric, the strength of the non-woven fabric,
The weight is in the range of 20 to 200 g / m 2 in terms of fluffiness and texture. In addition, a pigment, an additive for preventing the adhesion of fibers, for example, a wetting agent such as titanium oxide or fine silicon oxide, and various stabilizers may be added and mixed. Next, the 100% modulus applied to one side of the non-woven fabric is 3 kg / c
The binder resin of m 2 or less is, for example, a flexible polyurethane obtained by adjusting the amount of the soft segment or the type of the hard segment, an acrylic acid ester polymer or copolymer, and an acrylic acid ester and another polymer monomer. It is at least one kind of binder resin selected from a copolymer, a polymer of a diene monomer or a copolymer. The binder resin is applied to one surface of the non-woven fabric as a solution or dispersion. The method of applying the binder resin liquid can be performed by a roll coating method, a spray coating method, a transfer method, a knife coating method, etc., but a preferable method as a coating method for retaining only the nonwoven fabric surface portion is a roll coating method having a score. . The coating amount is 0.5 to 10 g / m 2 , preferably 1 to 7 g / m 2 in terms of the amount of resin, from the viewpoint of suppressing fluffing without impairing the soft texture of the non-woven fabric and enhancing drapeability and skin feel. The binder resin may be applied after embossing the non-woven fabric with a calendar embossing, or after applying the binder to the non-woven fabric and drying it, the uneven pattern is formed by heating the non-woven fabric to a temperature range from room temperature to softening the fiber. Alternatively, a roll or an endless belt having a pinpoint pattern may be used to press the non-woven fabric surface in which the binder resin and the fibers are mixed to densify the non-woven fabric surface and impart a pattern, whichever is convenient for the production process. You can select the method. In this way, the apparent density is 0.18-0.
A flexible non-woven fabric with a softness of 30 g / cm 3 and a good skin feel can be obtained. When this non-woven fabric is used as a patch substrate, the patch is obtained by applying a drug to the surface of the non-woven fabric to which the binder resin is not applied, so that the drug does not show through. Hereinafter, the sticking substrate of the present invention will be described with reference to the drawings.
