Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an adhesive tape for skin having nanofibers,

The present invention relates to a pressure-sensitive adhesive tape for skin having nanofibers and a method of manufacturing the same, and more particularly to a pressure-sensitive adhesive tape for skin having a nanofiber which can be used as an emergency bandage, surgical tape, large band- And a manufacturing method thereof.

It is common to use a bandage with a liquid-absorbent pad attached to the area corresponding to the upper surface of the window for the purpose of hemostasis, sterilization, and protection of the upper surface of the window when everyday trauma occurs. These bandages are medical products that users can buy from pharmacies and treat minor injuries without the doctor's prescription.

In such plasters, the adhesive tape for the skin generally has an adhesive layer formed on at least one surface of the substrate and is bonded to the surface of the target skin through such adhesive layer. The adhesive used for the adhesive layer of the adhesive tape for skin generally uses a rubber adhesive and an acrylic adhesive.

In addition, a wound dressing material and a patch material to be adhered to the skin using the adhesive tape, and the like include a support film as a support. Among them, the wound dressing material includes, for example, an absorbent material for absorbing and retaining exudates and a supporting film for supporting the absorbent material. This support film is required to have appropriate moisture permeability, water resistance, elongation and recovery rate. As the supporting film, polyvinyl chloride and nonwoven fabric are typically used.

The polyvinyl chloride film used as such a support film is widely used for wound dressings such as disposable bands (bandages) because of its low price. However, since the polyvinyl chloride film has low moisture permeability, when used over a long period of time, there is a problem that the skin is hydrated due to moisture, resulting in maceration. The smoke burns off the skin stratum corneum and causes secondary damage to the affected part. It has a bad influence. In order to solve the problem of polyvinyl chloride, a method of increasing the moisture permeability by perforating the film has been attempted, but the perforation has another problem that bacteria do not penetrate into the pores or are not waterproofed. In addition, when the polyvinyl chloride film is applied to a site such as a joint or the like, the polyvinyl chloride film has a problem of being easily lifted and falling.

Nonwoven fabric supports and paper used as support films are also inexpensive and easy to use. However, it has no defensive function or waterproof property against bacteria or foreign matter, and easily falls when applied to a bent part of the body. In addition, since the water vapor permeability is too high to keep the wound dry, there is a problem that the absorber adheres to the wound surface, causing damage to the new tissue during dressing replacement.

Examples of techniques for solving such problems are disclosed in Patent Documents 1 to 3 and the like.

For example, the following Patent Document 1 discloses a method for producing a porous nanofiber web, comprising the steps of preparing a thermoplastic polymer emissive polymer material, electrospinning the emissive polymer material to collect it as a porous nanofiber web, thermally fusing the electrospun nanofiber web by calendering A method for producing a porous nano-fiber nonwoven fabric, comprising the steps of: applying an adhesive composition to at least a part of a surface of a nano-web nonwoven fabric substrate, bonding the same by heat treatment to form an adhesive layer, and laminating a release film on the adhesive layer A non-woven fabric, and a non-woven fabric.

Patent Document 2 discloses a nonporous polyurethane outer film layer having a thickness of 10 to 50 占 퐉, a thickness of 0.05 mm to 5 mm, an average diameter of 1 to 800 占 퐉 and an opening ratio of pores of 30 to 80% A microporous polyurethane foam layer made of micropores, and a pressure-sensitive adhesive layer having a thickness of 10 to 50 占 퐉.

Also, Patent Document 3 discloses a method for producing a thermoplastic elastomer composition comprising a monomer composition comprising 40 to 80 wt% of a (meth) acrylic acid alkyl ester monomer, 10 to 59 wt% of an alkoxy group-containing ethylenically unsaturated monomer and 1 to 10 wt% 100 parts by weight of an acrylic copolymer obtained from a mixture and 20 to 120 parts by weight of a carboxylic acid ester which is a liquid or paste at room temperature, wherein the acrylic copolymer has a gel fraction of 30 to 80% by weight .

These and other objects and novel features of the present invention will become more apparent from the description of the present specification and the accompanying drawings.

The nanofibers prepared according to the present invention mean fibers having an average fiber diameter of 50 to 1,000 nm, which is the same for nanofibers which can be produced or prepared according to the present invention. The nanofibers can be produced by electrospinning a spinning solution or spinning melt containing a polymer. In the electrospinning for the production of nanofibers, a spinning solution is supplied through a spinning nozzle, a collector is installed in an opposite direction, and a high voltage of several tens kV is applied to the spinning space therebetween. Is produced. By this manufacturing method, nanofibers having a certain range of diameters are produced.

Such a nanofiber may be a thermoplastic or thermosetting resin such as a polyester resin, an acrylic resin, a phenol resin, an epoxy resin, a nylon resin, a poly (glycolide / L-lactide) copolymer, a poly (L- A resin, and a polyvinyl chloride resin, or may include a hydrophobic component such as fluorine.

Since the nonwoven fabric made of nanofibers has a fiber structure, pores exist between the entangled fibers. The material permeability of the nonwoven fabric is determined by the size of the pores. That is, the gas can freely pass through the pores provided in the nonwoven fabric, but the liquid state can not pass through the nonwoven fabric. In general, gaseous molecules or water vapor can be treated as particles with very small diameters. In the case of a monomolecular molecule, even if it is a volatile organic substance having a size of a few ohm-strong and composed of several atoms chemically bonded, there is no great change in the unit of the size. Water vapor is capable of intermolecular hydrogen bonding, with the diameter of water vapor ranging from tens to hundreds of nanometers.

The 'non-woven fabric' used in the present invention is a non-woven fabric such as a felt-like fabric prepared by arranging the nanofibers in a parallel or negative direction and processing the entangled nanofibers using heat and resin, Means a textile product which can be used as an emergency bandage, a surgical tape, a large band-aid having a pad, a bandage, and the like.

In addition, the average pore size formed on the nonwoven fabric provided according to the present invention is larger than that of the gas and can freely pass between the nanofibers. However, the liquid generally has a diameter of several hundreds of microns, The liquid is smaller than this and the liquid does not pass through the nonwoven fabric.

Also, since the adhesive layer coated on the nanofibers of the present invention is coated on the nanofiber itself in a molecular unit or less, pores such as a nonwoven fabric made of conventional nanofibers are maintained in the nonwoven fabric made of the nanofibers coated with the adhesive solution .
