Description

An apparatus for making nanofiber-mask packs with MD-direction different basis weights < RTI ID = 0.0 >

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 in the longitudinal direction To an electrospinning device.

In the nonwoven fabric used in the mask pack, since the fibers are bonded with the 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. Therefore, in order to remove wastes from damaged skin as described above, or to remove unnatural substances such as cucumber, citrus, aloe, carrot, wormwood, seaweed, carrot, ginseng, red ginseng, Potatoes, cacti, mesyl, vitamins, etc.) and minerals (elvan) have already been commercialized and marketed.

In recent years, a nanofiber layer has been widely used for manufacturing mask packs. The above-mentioned nanofiber layer has a remarkably improved skin adhesion, has a high impregnation efficiency of a moisturizing component and various nutrients, and is also excellent in diffusion effect of nutrients through the skin.

In the conventional general electrospinning, a certain number of nozzles are arranged in a specific direction in a unit for electrospinning, and a polymer solution is electrospun at room temperature to form a laminate of nanofibers 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 caused by the use of excessive solvent was inevitable.

In addition, the conventional mask pack has a disadvantage in that various nutrients impregnated into the sheet member and the accompanying water easily evaporate after a lapse of a predetermined time, and the cosmetic effect can not be sustained. Also, the sheet member is exposed to the air, Thus, the gel-like nutrients impregnated in the sheet member do not dissolve well, resulting in the problem that the nutrients are not well absorbed into the skin.

Although there has been much effort to solve the above problem, there has not yet been studied a device for manufacturing a mask pack using a polymer nanofiber layer having different basis weights in manufacturing a mask pack.

Disclosure of the Invention The present invention has been conceived to solve the above problems. It is an object of the present invention to provide a mask pack in which a nanofiber layer is stacked, in which the basis weight, i.e., the polymer density per unit area, It is another object of the present invention to provide an apparatus for producing a mask pack in which a nano fiber layer is laminated.

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.
