example 1

[0047] First, rayon PET spunlace (60 gsm) comprising viscose rayon and PET (weight ratio 8:2) (Namyang Textile Co., Ltd.) was prepared as a nonwoven fabric.

[0048] A polyurethane adhesive (0.3 g) was coated on the nonwoven to form a polyurethane adhesive coated rayon PET hydroentangled nonwoven.

[0049] A solution of PAN (6.30 g), hydrophilic PU (3.15 g), hot-melt PU (1.04 g) and pigment (0.01 g) in dimethylacetamide (89.5 g) was applied to the adhesive by electrospinning. On the nonwoven fabric coated with the mixture, the nanofiber coated nonwoven fabric is completed. At this time, the mass per unit area of ​​the nanofiber layer was adjusted to 0.4, 0.8, or 1.1 gsm.

[0050] The nanofiber-coated nonwoven was cut, and the resulting nonwoven sample was folded twice and placed in the shell of the facial mask. Then, a liquid cosmetic preparation (22 g, HongSam C&Tech) was incorporated into the case. The resulting packages were sealed and stored at room temperature for 3 da...

example 2

[0052] A nonwoven fabric sample obtained by the same procedure as Example 1 (except that the nanofibers have a mass per unit area of ​​0.3 gsm or 1.3 gsm) was folded twice and placed in the shell of the facial mask. Then, a liquid cosmetic preparation (22 g, HongSam C&Tech) was incorporated into these shells. The resulting package was sealed and stored at room temperature for 30 minutes to prepare the desired mask samples.

example 3

[0054] A nonwoven fabric sample obtained in the same procedure as in Example 1 was folded twice and placed in the shell of the facial mask. Then, a liquid cosmetic preparation (22 g, HongSam C&Tech) was incorporated into these shells. The resulting package was sealed and stored at room temperature for one day to prepare the desired mask samples.

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.

Description

technical field [0001] The present invention relates to a mask pack impregnated with a liquid cosmetic preparation, which is applied to the surface of human skin, in particular facial skin. Background technique [0002] Masks are generally used in the field of cosmetics to protect the skin from external irritation, dryness, etc. in particular. Conventionally, nonwoven facial masks in which the nonwoven fabric is impregnated with a liquid cosmetic formulation have been used for application to the facial skin surface. figure 1 A conventional nonwoven face mask is shown. [0003] However, such nonwoven masks have a thickness (about 15 μm to 50 μm) and a small surface area per unit volume, and thus, can be easily detached from the facial skin surface even with slight facial movement. In addition, nonwoven face masks were shown to have inferior long-term effects of liquid cosmetic formulations after attachment to the facial skin surface. [0004] In this regard, nanofiber-coat...
