(57) [Problem] To provide a deodorizing sheet for a human body capable of directly and efficiently removing body odor. SOLUTION: It is composed of a deodorizing nonwoven fabric and a stretchable pressure-sensitive adhesive sheet covering and fixing the deodorizing nonwoven fabric.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a deodorizing sheet that can be directly attached to a human body for use.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, various types of deodorizers using a deodorant have been put to practical use. However, all of these were placed in a fixed space such as a toilet, a clog box or a refrigerator, and were used for the purpose of removing bad smells and unpleasant odors from the air. Was something. In other words, it was impossible to directly and efficiently remove body odor with a conventional deodorizing device, and in fact, perfumes and the like had to be used for body odor.

[0003]

[Problems to be solved by the invention]

 The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a deodorizing sheet for a human body that can directly and efficiently remove body odor.

[0004]

[Means for Solving the Problems]

 The deodorizing sheet for human body of the present invention achieves the above object by comprising a deodorizing nonwoven fabric and a stretchable pressure-sensitive adhesive sheet covering and fixing the deodorizing nonwoven fabric.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic cross-sectional explanatory view of a nonwoven fabric used for a deodorizing sheet for a human body of the present invention, and FIG. 2 is a schematic cross-sectional explanatory view of a stretchable adhesive sheet used for a deodorizing sheet for a human body of the present invention.

In FIG. 1, reference numeral 1 denotes a deodorizing nonwoven fabric, which may be formed by binding a physical adsorbent such as activated carbon to the nonwoven fabric. Particularly good results are obtained by chemically bonding acid groups and carboxyl groups, rather than by physical adsorption, because it is possible to efficiently deodorize basic gases such as ammonia and amines that cause malodor by chemical reaction, not by physical adsorption. Can be

[0008] The nonwoven fabric in which the sulfonic acid group and the carboxyl group are chemically bonded is produced, for example, by applying a gamma ray simultaneous irradiation graft polymerization method as follows.

Manufacturing Example of Deodorizing Nonwoven Fabric Sodium styrene sulfonate (CH ₂ CHCHC ₆ H ₄ SO ₃ Na, hereinafter abbreviated as SSS) and acrylic acid (acrylic acid, CH ₂ CHCHCOOH, hereinafter) An aqueous solution of a monomer mixture (abbreviated as AAc) was permeated into a nonwoven fabric made of cellulose fibers. After replacing oxygen in the reaction vessel with nitrogen, gamma rays were irradiated, and SSS and AAc were co-grafted with the radical generated in cellulose as a starting point. Irradiation was performed at room temperature under a dose rate of 10 kGy / h. After a predetermined time, the nonwoven fabric was taken out and washed with water. The resulting material was immersed in hydrochloric acid to convert the functional group into H-form. Then, it was washed with water and dried to obtain a deodorizing nonwoven fabric.

In FIG. 2, reference numeral 2 denotes a stretchable pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer 2b formed on one surface of a gas-permeable support 2a. Is what you do. When the stretchable pressure-sensitive adhesive sheet 2 is not used, its pressure-sensitive adhesive layer 2b is covered with a release paper 2c.

In the deodorizing sheet for a human body according to the present invention, first, the release paper 2c of the elastic adhesive sheet 2 is peeled off, and the deodorizing nonwoven fabric 1 is placed almost at the center of the exposed adhesive layer 2b (see FIG. 3) and 4) in that state, it is used by sticking it to a desired part of the human body such as the sole of the foot (FIG. 5).

[0012]

[Effect of the invention]

 By using the deodorizing sheet for the human body of the present invention, the deodorizing nonwoven fabric can be stuck and fixed to a desired part of the human body with the stretchable adhesive sheet, so that the body odor can be directly and efficiently removed, and in particular, the offensive odor can be eliminated. It is effective to stick it on the sole of the foot, which is likely to occur.
