JP3013371U - Deodorant / antibacterial sheet - Google Patents

Abstract

(57) [Summary] [Purpose] Bedding used in homes and hospitals,
Sheets such as rugs and wall materials are provided with properties such as a high degree of deodorization without impairing their texture and aesthetics, and the purpose is to improve the surrounding environment and improve comfort. [Structure] Particles of an adsorbent or antibacterial powder and fibers forming the surface of a breathable sheet are partially adhered to each other through an adhesive resin, and the parts are aggregated and distributed in a layered form to form the powder. The body and the breathable sheet have a laminated structure.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is used for bedding, floor coverings, sheets for interior or base materials used in various homes, hospitals, and various other areas, and for deodorizing, antibacterial, and other aspects that have a health or hygiene orientation. Is.

[0002]

[Prior art]

 There are a wide variety of products for so-called deodorization (deodorization) and antibacterial, and there are various product forms depending on the place of use and purpose. Among them, a lot of sheets are known, but roughly speaking, the fibers themselves have deodorizing and antibacterial properties, those in which adsorbent particles such as activated carbon are coated on a sheet with a binder, or the adsorbability Examples include particles in which particles are enclosed between sheets or inside.

[0003]

[Problems to be solved by the device]

 Of these conventional sheets, the ones in which the fiber itself has deodorizing and antibacterial properties have a weak effect and cannot be expected to positively bring about environmental improvement in the vicinity in applications other than clothing. Even when using adsorbent particles such as activated carbon, the surface of the adsorbent particles must be exposed to the air in order to exert their adsorption / deodorization properties.If this is applied using a binder, After the binder is dried, a thin resin film covers the surface of the adsorbed particles, and if the resin film is extremely thin and breathable, some adsorption can be achieved, but most of the effect is lost. However, there was a problem that the binder filled the voids of the fiber to give it stiffness and rigidity, which impaired the feel and heat insulation. Furthermore, if the powder or granules are contained as they are in a breathable sheet, they tend to deviate to the outside, especially when they come into contact with water, activated carbon, etc. seeps out and stains black, and there are restrictions on the form of the sheet. was there. An object of the present invention is to solve such a difficulty.

[0004]

[Means for Solving the Problem] A granular material (1) having a property of adsorbing odorous particles, moisture, etc., such as activated carbon or silica gel, or having properties that are considered to be good for the human body due to antibacterial properties or far infrared rays (1) Particles (1 P) and the fibers (2P) forming the surface of the breathable sheet (2) are partially adhered to each other through the adhesive resin (3), and the parts are aggregated and distributed in a layered form, The sheet is such that the powder and granules (1) and the breathable sheet (2) have a laminated structure.

The breathable sheet (2) mainly corresponds to a non-woven fabric, a plain cloth, or a decorative cloth with a pattern (2A), and the adhesive resin (3) is mainly made of vinyl acetate, nylon, acrylic or the like. Such thermoplastics are applicable. Although the material itself such as the non-woven fabric may also serve as the adhesive resin (3), as a general rule, a resin which is easily melted by heat on the surface of the fiber (2P) is coated in advance, or the powder of the resin is mixed with the granular material ( By mixing with 1) and hot-pressing this, a sheet having a laminated structure can be obtained by a set of desired partial adhesion.

[0006] What is shown is an example showing the main mode, in which the adhesive resin (3) may have between the particles (1P) and also on the fiber (2P) on the opposite side, and the surface of the adhesive resin (3) Of course, it may not have the cloth (2A).

[0007]

[Action]

 The sheet of the present invention has a structure in which particles having adsorption (deodorization) or antibacterial properties are connected to fibers through an adhesive resin while leaving most of its surface exposed in the air, and thus exerts the adsorption force of the particles. The area that can be formed is extremely large, and it spreads widely in a plane shape, at the same time it does not impair its flexibility and texture, and it also has sufficient force to prevent particles from deviating or peeling.

[0008]

Example 1 A powder mainly composed of activated carbon and silica gel was placed in a thin layer between two non-woven fabrics together with vinyl acetate resin powder and heat-sealed, and this was used as a base material for a building interior.

[0009]

[Example 2] A cloth is laminated on both the front and back sides of "Example 1" to form a sheet or mat used for nursing care in a hospital or other wide range of bedding.

[0010]

[Example 3] A cross-shaped decorative cloth with a pattern is laminated on the surface of "Example 1", and this is used as an interior material such as a wide range of wall materials, floor materials, and ceiling materials. Needless to say, the present invention is not limited to such examples.

[0011]

[Effect of device]

 As described above, according to the present invention, the properties of activated carbon such as adsorption and deodorization can be fully exerted without impairing the texture and aesthetics of the seat, so that it is possible to maintain a comfortable environment in a wide range of fields. It has a very useful effect.
