Title: Mask pack sheet
Inventor: JEONG JONG CHEOL
IPC: D04H13/00
Filed: 2018-09-21
Abstract: The present invention relates to a mask pack sheet and, more particularly, to a mask pack sheet made of a non-woven fiber aggregate comprising lyocell fiber. The mask pack sheet is made of a non-woven fiber aggregate comprising lyocell fiber, and is characterized in that the fineness of the lyocell fiber is 1.0 to 1.4 denier. The mask pack sheet according to the present invention is made of a non-woven fiber aggregate comprising lyocell fiber and thus has improved flexibility. Accordingly, the mask pack sheet does not detach from the skin even after a long period of wearing, and has improved attachment to skin. The degree of absorption of essence or moisture and the transparency after essence or moisture treatment can be improved. In addition, the mask pack sheet can be used as a mask pack supporter sheet, thereby improving the attachment to skin and the feeling of wearing, and the excellent absorption enables effective supply of nutrients to the skin. Furthermore, the wet transparency is improved such that, when the mask pack sheet is tightly attached to the user's face, the color of the mask pack sheet appears transparent rather than white when the user's face is seen from the outside. Accordingly, the color of the mask pack sheet looks close to the color of the user's face such that less difference in appearance is noticeable, thereby providing an aesthetic appearance after wearing the mask pack.
