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. ...
