Mask pack

Abstract

A mask pack impregnated with a liquid cosmetic preparation, being applied to a human skin surface, in particular a facial skin surface. The mask pack includes a nonwoven fabric layer and a nanofiber layer including a hydrophilic polymer, wherein said nanofiber layer is bonded to the nonwoven fabric layer.

What is claimed is: 
     
         1 . A mask pack comprising:
 a nonwoven fabric layer; and   a nanofiber layer comprising a hydrophilic polymer;   wherein said nanofiber layer is bonded to the nonwoven fabric layer.   
     
     
         2 . The mask pack of  claim 1 , wherein the bond between the nanofiber layer and the nonwoven fabric layer is made by using one or more selected from the group consisting of an adhesive layer, a fusible film, heat, and ultrasonic waves. 
     
     
         3 . The mask pack of  claim 1 , comprising at least one additional layer interposed between the nonwoven fabric layer and the nanofiber layer. 
     
     
         4 . The mask pack of  claim 3 , wherein said additional layer is a bonding layer. 
     
     
         5 . The mask pack of  claim 4 , wherein said bonding layer comprises at least one adhesive. 
     
     
         6 . The mask pack of  claim 5 , wherein said adhesive is selected from the group consisting of an acrylic adhesive, a polyurethane adhesive, a polyester adhesive, and a silicone adhesive. 
     
     
         7 . The mask pack of  claim 1 , wherein the nonwoven fabric layer comprises at least one hydrophilic fiber selected from the group consisting of rayon, cotton, pulp, nylon and cellulose. 
     
     
         8 . The mask pack of  claim 1 , wherein the nonwoven fabric layer comprises a rayon fiber and a polyester (PET) fiber. 
     
     
         9 . The mask pack of  claim 8 , wherein the weight ratio of the rayon fiber and the PET fiber of the nonwoven fabric layer ranges from 5:5 to 9:1. 
     
     
         10 . The mask pack of  claim 1 , wherein the hydrophilic polymer of the nanofiber layer is at least one selected from the group consisting of polyacrylonitrile (PAN), hydrophilic polyurethane (PU), polyvinylalcohol (PVA), nylon, hydrophilic polyvinylidenefluoride (PVDF), hydrophilic polyethersulfone (PES) and polyetherimide (PEI). 
     
     
         11 . The mask pack of  claim 1 , wherein the nanofiber layer further comprises thermoplastic polyurethane (TPU). 
     
     
         12 . The mask pack of  claim 5 , wherein the contents of the nonwoven fabric layer, the nanofiber layer and the adhesive layer are respectively a range from 96.5 to 99 wt %, 0.05 to 0.5 wt % and 0.6 to 3 wt %, based on the total weight of the mask pack. 
     
     
         13 . The mask pack of  claim 1 , wherein the nanofiber layer further comprises hot-melt polyurethane (hot-melt PU). 
     
     
         14 . The mask pack of  claim 13 , wherein the hot-melt PU is used in an amount of 5 to 15 wt %, based on the total weight of a composition forming the nanofiber layer. 
     
     
         15 . The mask pack of  claim 1 , further comprising a liquid cosmetic preparation.
