Benefits of technology

The present invention provides a non-woven fabric that contains functional substances on the nanofiber, making it useful for a variety of applications such as surgical masks. The fabric has the functions of nanofiber and catechins, which offer antioxidant, antimicrobial, antiviral, deodorizing, and antifungal effects.

Problems solved by technology

A polymeric nanofiber manufactured by the electrospinning method has a smooth surface, and it is not necessarily easy to add surficial decorations and functions.

Polylactic Acid+Catechin Polyphenol+NaCl

[0100]A polylactic acid (Mitsui Chemicals, Inc.) was used as a base polymer, and a catechin polyphenol (Sunphenon BG-3, Taiyo Kagaku Co., Ltd., hereinafter called “catechin (Sunphenon BG-3)”) was used as a functional substance to make a non-woven fabric.

[0101]10 g of polylactic acid and 90 g of dichloromethane were mixed and a polylactic acid resin was dissolved at normal temperature (about 25° C.) to prepare a biodegradable polyester-containing solution (polymer-containing solution). In addition, ethanol was added to the catechin (Sunphenon BG-3) and dissolved to prepare a 20 wt % polyphenol compound-containing solution (functional substance-containing solution), in which 0.01 wt % of NaCl was further dissolved. The two solutions, 7.5 g of biodegradable polyester-containing solution and 2.5 g of polyphenol compound-containing solution were mixed to obtain a colorless and transparent mixed solution. This mixed solution (transparent solution co...

Polylactic Acid+Catechin Polyphenol

[0103]A polylactic acid (Mitsui Chemicals, Inc.) was used as a base polymer, and a catechin polyphenol (Sunphenon EGCg, Taiyo Kagaku Co., Ltd., hereinafter called “catechin (Sunphenon EGCg)”) was used as a functional substance to make a non-woven fabric.

[0104]10 g of polylactic acid and 90 g of dichloromethane were mixed and a polylactic acid resin was dissolved at normal temperature (about 25° C.) to prepare a biodegradable polyester-containing solution (polymer-containing solution). In addition, dimethylformamide was added to the catechin (Sunphenon EGCg) and dissolved to prepare a 20 wt % polyphenol compound-containing solution (functional substance-containing solution). Of the two solutions, 7.5 g of biodegradable polyester-containing solution and 2.5 g of polyphenol compound-containing solution were mixed to obtain a transparent mixed solution. This mixed solution (transparent solution containing the polylactic acid and catechin EGCg) was fill...

Polylactic Acid+Persimmon Tannin Polyphenol

[0106]A polylactic acid (Mitsui Chemicals, Inc.) was used as a base polymer, and a persimmon tannin polyphenol (odorless persimmon tannin: Osugi Co., ltd.) was used as a functional substance to make a non-woven fabric.

[0107]10 g of polylactic acid and 90 g of dichloromethane were mixed and a polylactic acid resin was dissolved at normal temperature (about 25° C.) to prepare a biodegradable polyester-containing solution (polymer-containing solution). In addition, dimethylformamide was added to the persimmon tannin polyphenol and dissolved to prepare a solution containing 20 wt % of polyphenol compound (functional substance-containing solution). Of the two solutions, 7.5 g of biodegradable polyester-containing solution and 2.5 g of polyphenol compound-containing solution were mixed to obtain a transparent mixed solution. This mixed solution (transparent solution containing the polylactic acid and persimmon tannin polyphenol) was filled into a...

Abstract

The purpose of the invention is to provide a surgical mask with sufficient antibacterial properties, by uniformly manifesting on the surface of nanofibers a functional material with antibacterial and antiviral properties. The problem is solved by a mask with a functional material which comprises a nanofiber containing at least one base polymer selected from a group consisting of PVA, polylactic acid, fibroin, chitosan, chitin, nylon 6, nylon 6,6, nylon 9T, nylon 610, polyamide, polystyrene, polyacrylonitrile, polyethylene terephthalate, polyvinyl chloride, polyurethane, polyester, zein, collagen and methoxymethylated nylon, and at least one functional substance selected from a group consisting of catechin polyphenols, persimmon tannin polyphenols, grape seed polyphenols, soybean polyphenols, lemon peel polyphenols, coffee polyphenols, phenylcarboxylic acid, ellagic acid and coumalin, and having a diameter of 1 nm to 2000 nm.

Description

TECHNICAL FIELD[0001]The invention relates to a medical mask with a functional material.BACKGROUND ART[0002]Techniques for manufacturing a nanometer sized polymer fiber by an electrospinning method have been known (Patent Literature 1). In the techniques, a polymer solution is released from a nozzle installed on the tip of a container in which the polymer solution as a raw material accumulates to a target electrode to which a high voltage is applied, thereby the polymer solution transfers from the nozzle to the target electrode, during that time, it becomes fibrous fibers along the line of electric force to manufacture the polymer fibers on the target electrode. This method allows manufacture of ten to several hundreds nanometer-ordered fibers or a sheet or a mat composed by gathering the fibers (nano fiver assembly).[0003]A polymeric nanofiber manufactured by the electrospinning method has a smooth surface, and it is not necessarily easy to add surficial decorations and functions. ...
