Description

TECHNICAL FIELD [0001] The present invention relates to an environmentally friendly thin film mask pack having excellent fit feeling, electric conductivity, and antibacterial property, and a manufacturing method thereof. [0002]

The present invention relates to a mask sheet and an environmentally friendly mask pack using the same. More particularly, the present invention relates to a thin film mask sheet having excellent electrical conductivity, antibacterial properties, and wearing comfort, and a thin film mask pack using the same.

The mask pack is a product in which a mask sheet obtained by processing a nonwoven fabric into a face shape is coated with various functional cosmetic materials including essence so as to wet the sheet. By attaching the mask pack to the face for a predetermined period of time, the applied functional material is absorbed into the face, thereby enabling management of the facial skin. Although a mask sheet using a nonwoven fabric has an advantage that it is inexpensive, a hydrogel sheet or a bio-cellulose sheet excellent in adhesion is being developed because of low adhesiveness.

In recent years, a method of applying a functional cosmetic material to a mask sheet having conductivity and applying electricity to improve the absorption rate of the functional material applied to the mask sheet has been developed.

Korean Patent Publication No. 10-2014-0004879 filed by Genic Co., Ltd. discloses a conductive mask pack comprising a support containing 1 to 20% by weight of conductive fibers and a cosmetic composition. The support containing conductive fibers may be selected from the group consisting of polyaniline, polyacetylene, polythiophene, polyalkylthiophene, polypyrrole, poly-isothianaphthene, poly (ethylene dioxythiophene), alkoxy- (3-hexylthiophene), cellulose fibers such as natural fibers and rayon such as cotton and hemp, cellulose fibers such as polyester, polyolefin (polyphenylene) sulfide, , And nylon, and is made into a mesh or nonwoven fabric.

Korean Patent Laid-Open Publication No. 10-2016-0035205 filed by Park et al discloses a method of promoting absorption of useful components by attaching a conductive sheet to the mask sheet.

Japanese Patent No. 16893450 issued to Kangho et al. Discloses a method of stimulating a mask pack with a patterned conductive carbon film support using a smartphone current.

However, such conductive mask sheets are problematic in that the basic properties of the conductive fibers are stiff and coarse, which makes them difficult to use as a mask sheet which is in direct contact with a face, which is one of the most sensitive areas in the human body.

On the other hand, Korean Patent Laid-Open Publication No. 10-2017-0058687 discloses an antimicrobial mask pack using an essence containing gold particles. Korean Patent Application No. 10-2016-7010218 filed by Kuraray Co., Ltd. discloses that an antibacterial ethylene-vinyl alcohol copolymer containing inorganic antibacterial microparticles dispersed therein is present in at least a part of the surface of the fiber, and an average of the inorganic antibacterial microparticles An antimicrobial nonwoven fabric sheet in which an antimicrobial fiber having a particle diameter of 0.01 to 20 탆 and an ethylene content of 10 to 70 mol% of the antibacterial ethylene-vinyl alcohol copolymer and a solvent spinning cellulose fiber are entangled with each other, It is possible to efficiently release the fluid composition by pressure or the like with good impregnation and lyophilicity when various fluid compositions are impregnated and to be able to release the fluid composition efficiently by pressure or the like, Low durability and low shrinkage due to impregnation of the composition leads to morphological stability It is possible to provide an antimicrobial nonwoven fabric sheet having excellent properties. However, such an antimicrobial sheet has a problem that an expensive material such as gold is used, or a nonwoven fabric is used, which results in poor adhesion.

A problem to be solved by the present invention is to provide a thin film mask pack which is excellent in wearing feeling and has electrical conductivity and antibacterial property.
