- Patent Document 1 JP-A-3-178664
- Patent Document 2 JP-A-11 9623
- an object of the present invention is to provide a pressure-sensitive adhesive covering material for sticking to the skin, which is particularly suitable for prevention and Z or treatment of pressure ulcers, in which the force of the sticking site is hard to peel off and wrinkles are hardly formed.
- the present inventor has focused on frictional force applied to the surface of a living body as a factor of pressure ulcer occurrence, and reducing this frictional force is a problem of pressure ulcers. It is thought that this will lead to the prevention of the development of pressure ulcers, and based on this idea, further research will be carried out, and the knitted fabric formed from the filament having a specific elongation and the specific elongation will be The present inventors have found that it is only necessary to form an adhesive layer on the film surface of a laminated support comprising a film having the above-mentioned film, and based on this finding, conducted further research and completed the present invention.
- a laminated support formed by laminating a knitted fabric on one surface of a film, and an adhesive layer formed on a surface opposite to the surface on which the knitted fabric of the film is laminated And a film having an elongation of 150 to 1,500% and a knitted fabric formed of a filament having an elongation of 1 to 200%. Is done.
- the filament forming the knitted fabric is a monofilament.
- the average diameter of the filaments forming the knitted fabric is preferably from 15 to 200 ⁇ m.
- the skin pressure-sensitive adhesive covering material for application of the present invention has a elongation of the knitted fabric is 20 to 600%, basis weight of the knitted fabric 10: a LOOgZm 2, knitted fabric coverage of the film surface 5 Preferably it is ⁇ 80%.
- the ratio of the elongation percentage in the longitudinal direction and the elongation ratio in the lateral direction of the knitted fabric is preferably 1.0 to 15.0.
- the film preferably has a thickness of 5 to 40 ⁇ m.
- the pressure-sensitive adhesive covering material for application to the skin of the present invention it is preferable that the pressure-sensitive adhesive contains a thermoplastic elastomer.
- the pressure-sensitive adhesive covering material for application to the skin of the present invention it is preferable that the pressure-sensitive adhesive contains a liquid component and Z or a hydrophilic substance.
- the pressure-sensitive adhesive covering material for application to skin of the present invention preferably has an elongation of 20 to 600% and a tensile stress at 20% elongation of 2.0 to 15. ONZl9mm.
- the pressure-sensitive adhesive covering material for application to the skin of the present invention preferably has a visible light transmittance of 2.5% or more.
- the adhesive covering material for sticking to the skin of the present invention preferably has a surface on the knitted fabric side having a dynamic friction force of 3.0 N / 40 cm 2 or less.
- the pressure-sensitive adhesive covering material for skin application of the present invention is applied to a site where a pressure ulcer has occurred to prevent the pressure ulcer from deteriorating. It is suitable as an adhesive covering material for preventing and preventing pressure ulcer for preventing ulcers or Z.
- the pressure-sensitive adhesive covering material for application to the skin of the present invention has an outer surface with excellent slipperiness, so that it is excellent in relieving external impact on the skin and friction with an object that comes into contact with the covering material, and from the application site. Since it is hard to be wrinkled, it is suitable as a pressure-sensitive adhesive covering material for sticking to the skin.
- the pressure-sensitive adhesive covering material for skin application of the present invention is particularly suitable for pressure ulcer prevention and Z or treatment, but the film, knitted fabric and pressure-sensitive adhesive constituting the pressure-sensitive adhesive covering material for skin application are also appropriately selected. By doing so, it is possible to observe the application site with external force, so that pressure ulcer prevention and Z or treatment can be effectively advanced.
- adhesive covering material for application to the skin of the present invention (hereinafter may be simply referred to as "adhesive covering material").
- Is composed of a laminated support obtained by laminating a knitted fabric on one surface of a film, and an adhesive layer formed on the surface of the film opposite to the surface on which the knitted fabric is laminated.
- the film constituting the laminated support needs to have an elongation of 150 to 1,500%. If the elongation is less than the above lower limit, in the adhesive covering material for skin application obtained using this film, it is difficult for the film to follow the extension of the skin, causing a feeling of discomfort during application, and the external or skin force. Also, the buffering ability of the steel against shear stress is reduced. On the other hand, if the elongation is larger than the upper limit, wrinkles and warpage are likely to occur in the film during use, and the slipperiness is reduced.
- the elongation of the film is preferably from 160 to 500%.
- the material constituting the film is not particularly limited as long as it has the above elongation rate.
- 1S polyurethane; polyolefin such as polyethylene and polypropylene; ethylene 'butyl acetate copolymer (EVA); Olefins such as acrylate copolymer (EEA), ethylene'methyl acrylate copolymer (EMA), ethylene'methyl methacrylate copolymer (EMMA), ethylene methacrylic acid polymer (EMAA), etc.
- Copolymers polyamides such as nylon 6, nylon 66; polyesters such as polyethylene terephthalate and polybutylene terephthalate; polybutyl alcohol; fluorinated resin; polychlorinated butyl; silicone; Among them, polyurethane, polyolefin, olefin copolymer and polyamide are preferred.
- One of these materials may be used alone, or two or more may be appropriately mixed. May be used.
- the thickness of the film is more preferably 10 to 30 ⁇ m, preferably 5 to 40 ⁇ m. If the film is too thin, it may be broken by repeated friction during use when the strength of the adhesive coating is not sufficient. On the other hand, if the film is too thick, the film becomes bulky and uncomfortable when affixed to the skin, and the followability particularly to a curved surface portion may be deteriorated.
- the laminated support used in the present invention is formed by laminating a knitted fabric on a film.
- the knitted cloth means a cloth composed of continuous stitches.
- the knitted fabric used in the present invention is composed of filaments.
- the filaments may be monofilaments or multifilaments.
- monofilaments makes it easy to obtain a smooth surface and makes it difficult for sheets etc. that come into contact with the filaments to bite into the filament surface. , Has good sliding properties. Further, when a monofilament is used, irregular reflection of light by the fiber can be suppressed, so that transparency is further improved.
- a monofilament refers to one filament (continuous long fiber) that can be used alone
- a multifilament refers to a filament in which two or more filaments are bundled.
- the filament used in the present invention needs to have an elongation of 1 to 200%.
- the elongation is preferably 1 to 40%. If the elongation is less than 1%, the whole knitted fabric becomes hard when the knitted fabric is composed of filaments, and an uncomfortable feeling is generated when the adhesive covering material obtained using this knitted fabric is applied to the skin, which is not preferable. . On the other hand, if the elongation is greater than 200%, body fittings such as sheets, covers, and underwear of futons and cushions that come into contact with the knitted fabric (hereinafter sometimes collectively simply referred to as “sheets, etc.”). It becomes easy to bite into the surface of the individual filaments constituting the knitted fabric, and as a result, the contact area with the sheets or the like increases, so that the slipperiness decreases.
- the average diameter of the filament is more preferably from 45 to 150 ⁇ m, preferably from 15 to 200 ⁇ m. If the average diameter force is too small, the management of the knitted fabric manufacturing process is complicated, and the filaments constituting the knitted fabric may be easily broken due to friction with sheets or the like during use of the adhesive coating material. On the other hand, if the average diameter is too large, a step is generated between the knitted fabric and the film constituting the laminated support, and, for example, a fiber product having an irregular surface may be formed by the knitting. When the fabric comes into contact with the surface of the fabric, the step is likely to cause the textile product to be easily caught by the step, which may reduce the slipperiness. Further, such a step may cause roughness on the surface, which may be unfavorable when the skin touches the surface.
