Abstract

The present invention relates to an electrospinning apparatus for manufacturing a mask pack, which comprises a spinning solution unit and is characterized by being radiated in a transverse direction in different weights, characterized by an electrospinning apparatus for manufacturing a mask pack .

Description

The present invention relates to an electrospinning device for manufacturing a mask pack including nanofibers having different basis weights in the transverse direction,

The present invention relates to an electrospinning apparatus for manufacturing a mask pack, and more particularly, to a mask pack comprising a substrate and a nano fiber layer, wherein the nano fiber layer has a basis weight different from each other in the transverse direction. To an electrospinning device.

A mask pack is a cosmetic product that replenishes the skin's physiological functions by covering the skin such as the face and supplying moisture and cosmetic ingredients to the skin to clean and make the skin beautiful. Such a mask pack is produced by impregnating synthetic fibers such as nonwoven fabric with various nutrients suitable for skin-beauty, as disclosed in the patent document 10-2011-0122473, and exerts a skin-beauty effect by attaching to the face for a predetermined time.

However, since nonwoven fabrics are bonded with synthetic resin adhesive, there is a fear of skin trouble when contacting with the skin, and sudden skin trouble occurs when the skin is sensitive or allergic.

In addition, the conventional mask pack has a disadvantage in that various nutrients impregnated into the sheet member and moisture accompanying thereto are easily evaporated after a lapse of a predetermined time, so that the cosmetic effect is not maintained. Also, The gel-like nutrient impregnated in the sheet member is not dissolved well, and the problem that the gel-like nutrients can not be absorbed to the skin is derived.

In recent years, a nanofiber layer has been widely used for manufacturing mask packs. When the nano fiber layer is used, it is possible to provide a mask pack in which the skin adhesion is greatly improved, the impregnation efficiency of the moisturizing component and various nutrients is high, and the diffusion effect of nutrients through the skin is also excellent.

The nanofiber layer is formed through electrospinning to contain the skin moisturizing component and the nutrient component as much as possible. Conventional electrospinning emits a certain number of nozzles in a specific direction in a unit for electrospinning to the front face of the substrate at a constant speed and time.

A typical electrospinning device has a structure such as a unit for electrospinning and a nozzle and a nozzle block installed inside the unit, thereby electrospinning a specific polymer solution under appropriate conditions to form a laminate of a nanofiber layer on a substrate.

At this time, the nanofiber layer laminated on the substrate by electrospinning is more effective in filtering foreign matter if it is manufactured so that the concentration of the polymer solution per unit area, that is, the basis weight, differs depending on the concentration of the pollutant and the degree of generation of foreign matter. However, in the conventional nanofiber filter, since the polymer solution is uniformly electrospun in the formation of the nanofiber layer, it is inevitable that the polymer solution is over-used and the production cost increases accordingly. In addition, the problem of environmental pollution due to the use of excessive solvents is inevitable.

However, there has been no report on a device for manufacturing a mask pack using a polymer nanofiber layer having different basis weights in manufacturing a mask pack.

SUMMARY OF THE INVENTION The present invention has been devised to solve the problems as described above, and it is an object of the present invention to provide an apparatus for manufacturing a mask pack in which a nanofiber layer having a basis weight, i.e., a polymer density per unit area, .

Basis Weight or Grammage is defined as the mass per unit area, that is, the preferred unit, grams per square meter (g / m 2). In recent years, for the purpose of making the air filter and the unit lighter and more compact, a type of the filter having a smaller depth is required, and if the filter material having the same filtration area is put in the unit, the filter material faces contact each other due to the thickness of the filter material, There has been a problem in that the pressure loss of the air filter unit remarkably increases. To solve this problem, there has been an attempt to reduce the thickness of the filter material for the air filter, that is, to reduce the basis weight. However, such an attempt has been made to reduce the basis weight of the filter, and it is possible to solve the pressure loss of the air filter unit sufficiently when the basis weight is reduced for a specific portion of the filter for each specific industrial field to which the filter is applied. The strength of the filter medium can be maintained.
