Description

[Detailed explanation of the idea]

[Technical field of the invention] The present invention is in a state where it is wrapped like an adhesive tape, and when used, it is cut to a required length and attached to personal items that tend to emit bad odors, such as shoes or bags, to eliminate bad odors. This invention relates to a deodorizing body that retains the function of deodorizing. [Technical background of the invention and its problems] There are generally two types of deodorants: physical deodorizers that absorb odors, such as activated carbon, and chemical deodorizers that use chemical reactions. It is provided in a fixed state in one container. These products have been commercialized with the aim of being installed in refrigerators and toilets, for example. By the way, there are many parts of personal belongings that need to be deodorized, such as shoes, which generate an extremely unpleasant odor, and even socks, which have a bad odor and give a feeling of discomfort. To solve this problem, various types of shoe insoles have been conventionally provided in which the above-mentioned activated carbon or a deodorizing agent produced by a chemical reaction is contained. However, the deodorizing function cannot always be obtained during the life of the insole, and the insole can be replaced every time the deodorizing function decreases, but this type of insole is relatively expensive, and in practice They are rarely replaced in a timely manner, and are often used as is, even though they are concerned about the bad smell. [Purpose of the invention] In view of the above-mentioned problems, the present invention can be easily replaced, has a flattened shape rather than being solidified into a lump, and can be easily moved to a desired position. The purpose is to obtain a deodorizing body that can be pasted and peeled off. [Summary of the invention] This invention is formed into a flat tape that can be easily cut to the required length by hand, is pasted and peeled off with an adhesive layer provided on one side, and has a chemical reaction with the adhesive layer. It contains a deodorant and retains its deodorizing function. By the way, a tape-like material that can be easily cut by hand can be obtained from paper, for example, but it can be accidentally cut when unwinding from the rolled-up state.
Requires a certain degree of tensile strength in the longitudinal direction. Therefore, flat yarns molded from thermoplastic synthetic resin such as polypropylene or polyethylene resin are woven into a tape shape as warp and warp yarns, but when comparing the warp and weft yarns, the thickness of the warp yarns is made thinner and the weaving density is increased. Driving with thicker weft threads

[Table] One side of the base fabric layer 1 is subjected to a corona discharge treatment and then extrusion laminated with low density polyethylene to form a laminate layer 4 having a thickness of about 50μ. After cooling the laminate layer 4, the other surface of the base fabric layer 1 is similarly subjected to the corona discharge treatment, and a laminate layer 5 made of low density polyethylene is again provided with a thickness of 30 μm. During this extrusion lamination process, a portion of the previous laminate layer 4 penetrates into the base fabric layer 1, and the thickness of the laminate layer 4 is reduced to about 40 microns. An adhesive layer 6 is provided on the surface of either the front or back laminate layer 4 or 5 by applying a pressure-sensitive adhesive containing a deodorizing compound 7 after corona discharge treatment.
Specifically, acrylic adhesive, solid content concentration
40%, toluene 50% as diluting solvent, ethyl acetate
50%, the amount of organic deodorizing compound added is 5%, and the coating amount of adhesive containing this deodorant is 100g/100g/
m ² and a coating thickness of 28μ. As a result of conducting strength tests on materials with the above structure, the values shown in the table below were obtained.

[Table] The tear force of 1.58 kg in the table above means that the material can be easily torn by hand. Therefore, as a result of performing a deodorization test on the above materials, the results shown in the table below were obtained.

[Table] In addition, the deodorizing body of the present invention is rolled up into a roll as shown in Figure 1, and cut to a required length at the time of use.For example, as shown in Figure 3, the deodorizing body piece 8 is pasted on the inner surface of the shoe 9. When the deodorizing effect becomes weak, the pasted deodorizing piece 7 can be peeled off and a new one can be pasted again. [Effects of the invention] The deodorizing body of the present invention is tape-shaped and can be easily cut by hand and pasted, so it can be reliably pasted even if the surface to which it is pasted is curved or bent. It can be used even if it is attached to shoes, etc., and can be easily replaced. Also, the deodorant is mixed in the adhesive layer, so if it gets mixed in with other layers, it will be dissipated by the heat during processing and its effectiveness will be weakened.
Since it is mixed into the adhesive layer, it will not be released during processing, and its deodorizing function can be maintained for a long time.
