Definitions
- the present invention relates to a cosmetic pack and a method for manufacturing the same, wherein the functional material is absorbed into the skin when attached to the skin in a dry type.
- Conventional cosmetic packs contain essences containing nutrients such as natural extracts, proteins and vitamins on woven or non-woven fabrics to produce functions such as whitening, wrinkle improvement, hydration, skin trouble relief, and skin elasticity. Has been.
- the conventional cosmetic pack is manufactured based on a woven or nonwoven fabric, sufficient adhesion is not achieved at the interface in contact with the skin, and thus, the active ingredient cannot be sufficiently delivered to the depth of the skin, and an excess essence is added to the skin. The adhesion and adhesion have been improved.
- hydrogel type cosmetic pack has been used in recent years.
- the hydrogel cosmetic pack has excellent fit, but can be used for daily activities, but the thickness is not only limited to the adhesiveness but also has an inconvenience of having to remove the excess essence after the flow down or wearing time.
- nanofibers having a diameter of less than 1 ⁇ m using an electrospinning technique may be formed in a laminated structure having a three-dimensional pore structure at the same time of manufacture and may provide a much larger skin contact area than conventional woven or nonwoven fabrics when used in the cosmetic field.
- the nanofibers can be produced in the form of nanofibers loaded with functional materials by mixing and spinning various functional materials in the spinning solution.
- the core part is made of polyurethane and the core part is made of polyurethane, and the cell part in contact with the skin is made of biodegradable polymer to minimize trouble with the skin. If 100% of the residual solvent is not removed due to the use of a solvent, there is a problem of secondary contamination by the residual solvent.
- an object of the present invention is to manufacture a dry sheet form using a nanofiber web containing a functional material, easy and convenient storage and packaging, attaching the dry sheet to the face is convenient to use the cosmetic pack and its manufacturing method To provide.
- Another object of the present invention is to provide a cosmetic pack and a method for manufacturing the same, which is provided with a shape maintaining part to maintain the shape of the moisturizing oil and cosmetic packs and to form a printing layer on the shape maintaining part to beautify the design. .
- Still another object of the present invention is to provide a cosmetic pack and a method for manufacturing the same, which are transparent when the solvent is contained in the shape-retaining part, which turns white when dried, to grasp when the cosmetic pack is removed.
- the cosmetic pack of the present invention is laminated on the support and the support to be separated by water, and formed by electrospinning a polymer material, a water-soluble polymer material and a functional material, dry type and functional by water
- the material includes a membrane that melts.
- the support may be formed of any one of nonwoven fabric, mesh, silicone, PET, PE, PP, and PU.
- the membrane may be attached with a release film that protects the membrane and separates in use.
- the fibers of the support and the fibers of the membrane are entangled with each other, and are laminated with each other.
- the support and the membrane may be separated from each other.
- the membrane may be formed in the form of a nano-web by electrospinning a spinning solution mixed with a polymer material, a water-soluble polymer material, a functional material and a solvent, and by collecting the nanofibers.
- the membrane may include a shape maintaining part made of a polymer material and a chemical liquid part made of a water-soluble polymer material and a functional material.

Abstract
본 발명의 미용 팩은 지지체와, 상기 지지체에 수분에 의해 분리되도록 적층되고, 고분자물질, 수용성 고분자물질 및 기능성 물질을 전기방사하여 형성되고, 수분에 의해 기능성 물질이 녹는 멤브레인으로 구성되어, 보관 및 포장이 쉽고 편리하며 건조한 시트를 얼굴에 부착하므로 사용이 편리하다.
Description
본 발명은 건식 타입으로 피부에 부착시 기능성 물질이 피부에 흡수되는 미용 팩 및 그 제조방법에 관한 것이다.
종래 일반적인 미용 팩은 직포나 부직포상에 천연 추출물, 단백질, 비타민 등의 영양 물질을 포함하는 에센스를 함유시켜, 미백, 주름개선, 수분공급, 피부 트러블 완화, 피부 탄력 부여 등의 기능을 가지도록 제조되어 왔다.
하지만, 종래의 미용 팩은 직포나 부직포를 기반으로 제조되므로 피부와 접촉하는 계면에서 충분한 밀착이 이루어지지 않아 유효성분을 피부의 깊은 곳까지 충분히 전달할 수 없었으며, 과량의 에센스를 첨가하여 피부와의 접착력이나 부착력을 향상시켜왔다.
따라서 종래 미용 팩을 부착하고 활동하는데 미용 팩 자체의 자중에 의한 흘러내림과 초과된 에센스의 흘러내림에 의해 사용이 불편하고, 에센스가 낭비되는 단점도 있었다. 또한 미용 팩을 착용하게 되면 일상적인 활동이 어렵게 되는 경우도 많아 착용시간 내내 누워있게 되기도 한다.
이러한 단점을 해결하기 위해 최근에는 하이드로겔 타입의 미용 팩이 많이 사용되고 있다. 하이드로겔 미용 팩은 착용감이 우수하여 일상적인 활동이 가능하기는 하나 두께가 두꺼워 밀착성에 한계가 있을 뿐만 아니라 과잉의 에센스의 흘러 내림이나 착용 시간이 지난 후에는 별도로 떼어내어야 하는 불편함이 있었다.
최근, 전기방사 기법을 이용하여 섬유의 직경을 1㎛ 미만의 나노섬유에 대한 연구가 활발하게 진행되고 있다. 이러한 나노섬유는 제조와 동시에 3차원 세공구조를 갖는 적층구조로 형성되어 미용분야에 이용할 경우 종래 직포나 부직포에 비해 월등히 큰 피부 접촉면적을 제공할 수 있다. 또한, 나노섬유 제조시에 각종 기능성 물질을 방사용액에 혼합하여 방사함으로써 기능성 물질이 탑재된 나노섬유 형태로 제조가 가능하게 되었다.
종래의 마스크 팩은 한국 공개특허 10-2011-080066호에 개시된 바와 같이, 부직포상에 2중층의 나노섬유층을 형성하고, 상기 2중층의 나노섬유층 상에 플라즈마로 표면 처리한 피부 미용 팩를 제안하고 있다. 그러나 이 기술은 부직포상에 나노섬유층을 복합화하는 공정과 플라즈마 처리 등의 2차 공정을 포함하여 공정비용이 상승한다.
또한, 부직포와 나노 섬유층을 복합화하는데 화학적 접착제 등을 사용한 라미레이션, 열 융착 또는 초음파 본딩 등의 공정이 필요하게 되고, 접착제 등을 사용하지 않을 경우 기능성 에센스나 수분 등에 의해 부직포와 나노섬유층 간의 박리가 일어날 가능성도 있다.
더욱이, 2중층 구조의 나노섬유를 방사하는데 있어 코어/셀 형태로 방사하여 코어 부분은 폴리우레탄 등으로 하고, 피부와 접촉하는 셀 부분은 생분해성 고분자를 이용하여 피부와의 트러블을 최소화하려 했으나 독성 용매의 사용으로 인해 잔류용매를 100% 제거하지 않을 경우 잔류용매에 의한 2차 오염의 문제를 가지고 있다.
특히, 상기 종래기술에서 사용한 대부분의 생분해성 고분자는 소수성 특성으로 인해 플라즈마 공정을 통해 친수화 처리하는 것이 반드시 필요하므로 공정비용의 상승은 물론 방사시 탑재된 기능성 물질의 변질을 야기할 수 있는 문제점도 아울러 가지고 있다.
따라서, 본 발명의 목적은 기능성 물질이 포함된 나노섬유 웹을 사용하여 건조한 시트 형태로 제조함으로써, 보관 및 포장이 쉽고 편리하며, 건조한 시트를 얼굴에 부착하므로 사용이 편리한 미용 팩 및 그 제조방법을 제공하는 데 있다.
본 발명의 다른 목적은 형상 유지부가 구비되어 보습유지 및 미용 팩의 형태를 유지할 수 있고 형상 유지부에 인쇄층을 형성할 수 있어 디자인을 아름답게 할 수 있는 미용 팩 및 그 제조방법을 제공하는 데 있다.
본 발명의 또 다른 목적은 형상 유지부에 용제가 함유되면 투명한 형태이고, 마르면 흰색으로 변화되어 미용 팩 제거시점을 파악할 수 있어 사용이 편리한 미용 팩 및 그 제조방법을 제공하는 데 있다.

상기 형상 유지부는 용제가 함유된 상태에서는 투명한 형태이고, 용제가 마르면 육안으로 확인이 가능한 색상으로 변화될 수 있다.
본 발명의 미용 팩 제조방법은 릴리이스 필름에 고분자물질, 수용성 고분자물질, 기능성 물질 및 용매가 혼합된 방사용액을 전기방사하여 건식 타입 멤브레인을 형성하는 단계와, 상기 멤브레인에 지지체를 적층한 후 압착하여 지지체의 섬유와 멤브레인의 섬유가 서로 얽히도록 하여 상호 합지하는 단계와, 상기 멤브레임, 지지체 및 릴리이스 필름을 커팅하여 형상화하는 단계를 포함할 수 있다.

도 5는 본 발명의 다른 실시예에 따른 미용 팩의 평면도이다.
도 6은 본 발명의 일 실시예에 따른 미용 팩 제조장치의 구성도이다.
이하, 첨부된 도면들을 참조하여 본 발명에 따른 실시예를 상세히 설명한다. 이 과정에서 도면에 도시된 구성요소의 크기나 형상 등은 설명의 명료성과 편의상 과장되게 도시될 수 있다. 또한, 본 발명의 구성 및 작용을 고려하여 특별히 정의된 용어들은 사용자, 운용자의 의도 또는 관례에 따라 달라질 수 있다. 이러한 용어들에 대한 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 한다.
도 1을 참조하면, 본 발명의 일 실시예에 따른 미용 팩은 지지체(20)와, 지지체(20)에 적층되고 얼굴에 부착되는 멤브레인(10)과, 멤브레인(10)에 적층되고 사용할 때 분리되는 릴리이스 필름(30)을 포함한다.
지지체(20)는 멤브레인(10)을 지지하는 역할을 하는 것으로, 부직포가 사용될 수 있다. 그리고 지지체(20)는 부직포 이외에, 실리콘, PE, PE, PP, PU 등 미용 팩을 지지할 수 있는 다양한 재질을 사용할 수 있다.
지지체(20)는 디자인을 아름답게 하면서 미용시트 전체를 지지할 수 있는 메쉬가 사용될 수 있다. 메쉬는 은사, 섬유사, 알루미늄 재질의 와이어, 수지재질의 실을 제직하여 형성된다.
릴리이스 필름(30)은 릴리이스 필름(30)은 PET, PP, PE 재질 또는 이형지 등으로 형성되어 멤브레인(10)을 충분히 지지할 수 있는 강도를 가진다.
멤브레인(10)은 전기방사 가능한 고분자 물질, 수용성 고분자 물질 및 기능성 물질을 전기방사하여 나노 웹 형태로 형성된다.
즉, 멤브레인(10)은 수용성 고분자물질, 기능성 물질 및 용매를 적정 비율로 혼합한 방사용액을 전기 방사하여 섬유직경 3㎛ 미만인 나노섬유를 형성하고, 이 나노섬유가 축적되면 나노섬유 웹 형태로 형성된다.
이러한 멤브레인(10)은 도 2에 도시된 바와 같이, 고분자 물질로 이루어지고 멤브레인(10)의 형상 유지 및 에센스를 흡수하는 역할을 하는 형상 유지부(12)와, 기능성 물질이 포함된 수용성 고분자물질로 이루어지고 용제에 의해 용해되는 약액부(14)를 포함한다.
지지체(20)와 멤브레인(10)은 상호 압착하면 지지체(20)의 섬유와 멤브레인(10)의 섬유가 서로 얽힌 상태로 되어 상호 합지되고, 수분이 투입되어 멤브레인(10)의 기능성 물질 녹으면 서로 분리된다.
따라서, 멤브레인(10)을 얼굴에 부착한 후 수분을 투입하면 지지체(20)를 멤브레인(10)에서 쉽게 분리할 수 있어 얼굴에는 투명한 상태인 멤브레인(10)만 부착되므로 멤브레인(10)을 얼굴에 부착한 후 활동하기 편리하다.
형상 유지부(12)와 약액부(14)는 한 번의 전기방사에 의해 일체로 형성되기 때문에 나노섬유가 고분자물질과 수용성 고분자물질이 혼합된 형태 또는 적층되는 형태로 형성될 수 있다.
즉, 도 2에 도시된 바와 같이, 나노섬유(40)의 단면을 보면 고분자물질로 이루어지는 형상 유지부(12)와 수용성 고분자물질로 이루어지는 약액부(14)가 혼합된 형태로 되거나, 형상 유지부(12)와 수용성 고분자 물질이 적층되는 형태로 된다.
이러한 멤브레인(10)을 얼굴에 부착하면 약액부(14)는 용제에 의해 용해되어 기능성 물질이 피부에 흡수되고 수용성 고분자물질은 지지체(20)에 흡수된다. 그리고, 형상 유지부(12)는 용해되지 않고 멤브레인(10)의 형태를 유지한다.
이때, 형상 유지부(12)는 고분자 물질을 전기방사하여 나노섬유가 축적된 나노섬유 웹 형태로 형성되므로 에센스가 흡수된 상태 즉, 용제를 함유한 상태일 때에는 난반사를 없애주어 투명하게 보이고, 에센스가 없는 상태, 즉, 용제가 마른 상태가 되면 흰색 또는 흰색 이외의 다른 색으로 보이기 때문에 약액부(14)의 기능성 물질이 피부에 전부 흡수된 것을 육안으로 확인할 수 있다.
이와 같이, 약액부(14)의 기능성 물질이 전부 피부에 흡수되어 용제가 마르게 되면 형상 유지부(12)가 흰색으로 변화되어 미용 팩의 제거 시점을 사용자가 육안으로 알 수 있다.
그리고, 나노섬유(40)는 도 3에 도시된 바와 같이, 고분자물질로 이루어지는 형상 유지부(12)가 중심에 배치되고, 형상 유지부(14)의 외면에 수용성 고분자물질로 이루어지는 약액부(14)가 감싸지는 형태로 형성될 수 있다.
이는 형상 유지부(12)를 형성하는 고분자물질과 약액부(14)를 형성하는 수용성 고분자물질이 서로 다르기 때문에 전기방사를 하게 되면 형상 유지부(12)가 중앙에 배치되고, 약액부(14)가 형상 유지부(12)의 외면에 감싸지게 배치되는 코어 쉘 구조를 가질 수 있다.
형상 유지부(12)를 형성하는 고분자물질과, 약액부(14)를 형성하는 고분자물질은 분자량이 서로 다르거나 녹는점이 서로 다르기 때문에 코어 쉘 구조를 가질 수 있다.
이러한 멤브레인(10)을 얼굴에 부착하면 형상 유지부(12)의 외면에 감싸진 약액부(14)는 용제에 의해 용해되어 기능성 물질은 피부에 흡수되고 수용성 고분자물질은 지지체(20)에 흡수된다. 그리고, 형상 유지부(12)는 용해되지 않고 멤브레인(10)의 형태를 유지한다.
기존의 미용 팩은 피부에 부착한 후 정해진 일정시간이 경과되면 미용 팩을 얼굴에서 분리하는데, 사람에 따라 미용 팩이 피부에 흡수되는 시간이 각각 다르다. 따라서, 정해진 시간에 따라 미용 팩을 떼어내는 시점으로 하면 미용 팩에 함유된 기능성 물질이 전부 얼굴에 흡수되지 못하거나 기능성 물질이 전부 흡수된 상태에서 계속 얼굴에 부착하고 있는 경우가 발생된다.
본 발명의 형상 유지부(14)는 용제가 마르면 투명에서 흰색으로 변화되기 때문에 미용 팩을 얼굴에서 분리하는 시점을 육안으로 확인이 가능하여 사용이 편리하다.

다음에서 미용 팩의 제조공정을 설명한다.
도 6은 본 발명의 일 실시예에 따른 미용 팩 제조장치의 구성도이다.
본 발명의 미용 팩 제조장치는 고분자물질, 수용성 고분자물질, 기능성물질 및 용매가 혼합된 방사용액이 저장되는 저장탱크(50)와, 고전압 발생기가 연결되고 저장탱크(50)와 연결되어 나노섬유(40)를 형성하는 방사노즐(60)과, 방사노즐(60)의 하측에 설치되어 방사노즐(60)에서 형성되는 나노섬유(40)가 축적되어 나노 웹을 형성하는 콜렉터(80)를 포함한다.
콜렉터(80)와 방사노즐(60) 사이에 90~120Kv의 고전압 정전기력을 인가함에 의해 방사노즐(60)에서 나노섬유(40)가 방사되고, 콜렉터(80)에 나노섬유(40)가 축적되어 나노섬유 웹 형태의 멤브레인(10)을 형성한다.
콜렉터(80)의 전방에는 릴리이스 필름(30)가 감겨진 릴리이스 필름 롤(70)이 구비되고, 콜렉터(80)의 후방에는 지지체(20)이 감겨진 지지체 롤(72)이 구비된다.
이와 같이, 구성되는 미용 팩 제조장치를 이용하여 미용 팩을 제조하는 공정을 다음에서 설명한다.
먼저, 콜렉터(80)가 구동되면, 릴리이스 필름 롤(70)에 감겨진 릴리이스 필름(30)이 콜렉터(80)의 상면으로 공급된다.
그리고, 콜렉터(80)와 방사노즐(60) 사이에 고전압 정전기력을 인가함에 의해 방사노즐(60)에서 방사용액을 나노섬유(40)로 만들어 릴리이스 필름(30)에 방사한다. 그러면 릴리이스 필름(30)에 나노섬유(40)가 축적되어 나노섬유 웹 형태의 멤브레인(10)이 형성된다.
여기에서, 나노섬유(40)는 고분자물질로 이루어지고 용제에 용해되지 않는 형상 유지부(12)와, 기능성 물질이 포함되는 수용성 고분자 물질로 이루어지고 용제에 용해되는 약액부(14)가 혼합된 상태로 방사된다.
