Problems solved by technology

[0006] However, even with this technology, due to the limitations of the physical properties of the material forming the synthetic fiber itself, the stretchability is poor, and when it is made into a mask sheet and used on the skin, it will cause inconvenience in movement, and when the facial expression changes or it is applied for a long time When applied, it will peel off from the skin
[0007] In addition, thermoplastic resins such as polypropylene fiber (PP fiber), polyester fiber (PET fiber), polyethylene fiber (PE fiber), polyvinyl alcohol fiber (PVA fiber) or polylactic acid fiber (PLA fiber) do not have hydrophilic properties. Therefore, the wettability for cosmetic compositions is reduced, thereby limiting when used as a mask sheet for impregnating cosmetics

Embodiment 1

[0082] By combining cellulose pulp with a degree of polymerization (DPw) of 820 and an α-cellulose content of 93.9% with NMMO / H with a propyl gallate content of 0.01% by weight 2 O mixed solvents (weight ratio 90 / 10) are mixed to make lyocell fibers with a spinning stock solution whose cellulose pulp content accounts for 10% by weight (spinning stock solution concentration 10%) of the total weight of the mixture.

[0083] First, in the spinning nozzle, while maintaining the spinning temperature of the spinning stock solution at 110°C, the discharge amount of the spinning stock solution and the spinning speed are adjusted to spin so that the single fineness of the filament becomes 1.25 denier you. The filamentous spinning dope discharged from the spinning nozzle continuously passes through the air gap section and is supplied to the coagulation liquid in the coagulation tank. At this time, in the air gap section, the cooling air coagulates the spinning dope for the first time a...

Embodiment 2

[0089] A nonwoven fiber assembly having a single fineness of 1.25 denier was produced in the same manner as in Example 1 except that the basis weight of the nonwoven fiber assembly was adjusted to 40 gsm.

Embodiment 3

[0091] A nonwoven fiber assembly having a single fineness of 1.25 denier was produced in the same manner as in Example 1 except that the basis weight of the nonwoven fiber assembly was adjusted to 50 gsm.

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-wovenfiber 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 packsupporter 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 transparencyis 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 afterwearing the mask pack.

Description

technical field [0001] The present invention relates to a face mask sheet, and more particularly to a mask sheet formed from a nonwoven fiber assembly comprising lyocell fibers. Background technique [0002] A mask refers to a product that is in contact with the face for a long time to nourish the skin. In the field of cosmetics, moisturizers and whitening agents that contain liquid or gel ingredients are used to moisturize the skin, remove waste, whiten, and improve skin health. Active substances such as ingredients useful to the skin or cosmetic compositions are impregnated into a patch as a carrier. [0003] The mask sheet used as the carrier of the mask uses natural fibers such as cotton, silk, hemp, silk, etc., but it is difficult to adhere to the multi-curved face, and it is not easy to adjust the absorption, etc. Therefore, non-woven fabrics made of synthetic fibers and their mixtures are used. There are many cases of woven fiber aggregates. [0004] As the material...
