Abstract
본 발명은 도액관이 납작해지지 않으며 또한 천과 같은 촉감과 외관을 갖는 흡수체 표면시이트에 관한 것이다. 흡수체(1)의 표면 시이트(2)는 도액관(15)을 갖춘 용융 취입형 부직포로 이루어진 상부 시이트층(10)과, 이 시이트층(10)의 이면측에 있고 도액관(15)과 그 이면측의 개구부(15b) 근방에서 접합되는 하부 섬유층(11)으로 구성된다. 용융 취입형 부직포는 표면 시이트(2)에 천모양의 촉감과 외관을 주며, 하부 섬유층(11)은 도액관(15)을 보강하여 도액관(15)이 납작해지거나 그 선단 개구부(15b)가 변형되는 것을 방지한다.
Description
제1도는 본 고안의 표면 시이트를 이용한 생리대의 부분 파단 사시도.
제2도는 제1도의 X-X선 단면의 부분 확대도.
*도면의 주요부분에 대한 부호의 설명
1:체액 흡수성 물품(생리대) 2:표면 시이트
3:이면 시이트 4:흡수체
10:상부시이트층 11:하부 섬유층
15:도액관 15b:선단 개구부
본 고안은 생리대, 1회용 기저귀 등의 1회용 체액 처리용품에 사용하는 투액성 표면 시이트에 관한 것이다.
종래에는 1회용 체액 처리 용품의 투액성 표면시이트에 개구 플라스틱 시이트나, 부직포를 소재로서 사용하는 일이 많았다. 개구 플라스틱 시이트의 경우에는 표면에서 이면 방향으로 신장되는 도액관을 형성시키고 그 선단 개구부를 흡수체에 접촉해 놓으면 체액을 신속히 흡수체로 이행시킬 수 있다. 이와 같은 종류의 기술에 관해서 예를들어, 특공소 57-17081호 공보에는 테이퍼(taper)를 갖는 도액관이 개시되어 있고, 또 특개소 60-259261호 공보에는 원통상의 도액관이 개시되어 있다. 한편 부직포의 경우에는 플라스틱 시이트에 없는 유연한 감촉이 있어, 착용감이 좋은 체액 처리용품을 제조할 수 있다.
이와 같은 잇점을 갖는 종래 기술이지만, 개구 플라스틱의 경우에는 플라스틱 시이트의 특유의 매끄러운 감촉이나 광택이 있는 외관이 좋지 않아 그것을 대신하여 천과 같은 감촉 또는 외관으로 근접시키는 연구가 종종 요구되고 있다. 또 부직포의 경우에는 개구 플라스틱 시이트와 같이 신속히 체액을 흡수체로 이행시키고, 이행후에는 시이트 표면을 건조 상태로 유지하는 능력, 이른바 건조한 촉감이 적으므로 그점에 대한 개량이 요구된다. 이들 양소재의 장점을 살리고 단점을 보완하는 것을 목적으로 열가소성 섬유를 융착하여 시이트 형상으로 한 용융 취입형 부직포를 사용하는 기술이 예를들어 특개평 3-51355호 공보에 개시되어 있다. 이 기술에 의하면 천모양의 유연한 감촉과 광택이 적은 외관을 갖춘 도액관이 형성된 표면시이트를 만들 수가 있다. 그러나 용융 취입형 부직포는 일반적으로 섬도(纖度)가 작고, 그로 인해 흐늘흐늘하고, 도액관이 체압을 받아서 납작해지거나, 선단 개구부가 변형되기 쉽고, 체액의 신속한 이행이 방해되기 쉬운 문제점이 있다. 그러므로 본 고안에서는 용융 취입형 부직포로 구성되고, 또 도액관을 갖춘 상부시이트층과 그 이면측에 형성시킨 하부섬유층으로 표면 시이트를 구성함으로써 상기 문제를 해결하는 것을 과제로 한다.
본 고안이 상기 과제를 해결하기 위한 요지는 표면에서 이면 방향으로 신장하는 도액관을 갖춘 체액 흡수성 물품의 표면 시이트를 전제로 하고, 이 표면 시이트를 용융 취입형 부직포로 구성하고, 또 도액관을 갖춘 평균 중량이 10-100g/㎡인 상부 시이트층과, 이 상부 시이트층의 이면측에 있고 상기 도액관과 그 선단 개구부 근방에서 접합되는 섬도 1-10 데닐·평균중량10-40g/㎡·밀도 0.01-0.1g/㎡의 하부 섬유층으로 구성되는 것이다.
본 고안에 관한 표면시이트는 용융 취입형 부직포로 구성되는 상부 시이트층과, 그 이면측에 있고 도액관의 선단부와 접합되는 하부 섬유층으로 구성되고, 도액관의 형상을 이 하부 섬유층에 의해 보강하도록 구성하므로서 이 도액관은 잘 납작해지지 않고 선단 개구부가 변형되는 일도 적다. 그로 인해 표면 시이트로부터 흡수체로의 체액의 이행이 신속하고, 그 밖에 천 모양의 감촉과 외관을 얻을 수 있다.
[실시예]
본 고안의 상세한 것을 첨부 도면을 근거로 하여, 이하에 설명한다.
제1도는 본 고안의 표면 시이트(2)를 이용한 생리대(1)를 일부 파단하여 도시한 사시도(斜視圖)이다. 생리대(1)는 투액성 표면 시이트(2), 불투액성이면 시이트(3), 및 이들 양시이트(2), (3)간에 개재되는 흡수체(4)로 구성되고, 이 흡수체(4)의 주위까지 신장된 양시이트(2), (3)는 면밀히 접합되어 있다.
제2도는 제1도의 X-X선 단면의 부분 확대도이고, 표면 시이트(2)를 상세히 도시하고 있다. 표면 시이트(2)는 열가소성 섬유가 상호 융착되어서 구성되는 상부 시이트층(10)과 이 시이트층(10)에 강성(剛性)을 부여하기 위하여 그 이면에 형성시킨 하부 섬유층(11)으로 구성되어 있다. 상부 시이트층(10)에는 그 표면(12)으로부터 이면(13) 방향으로 신장되고 상하단에 개구부(15a), (15b)를 가지는 도액관(15)을 형성시켜 이 시이트층(10)을 투액성으로 구성한다. 그 투액성을 현저히 손상시키지 않는 정도로 하부 섬유층(11)은 개구부(15b)를 피복하고, 또 최소한 일부의 도액관(15)과 개구부(15b)의 근방에 고온용융 접착제(18)를 개재시킴으로써 접합되고 있다. 이와 같은 하부 섬유층(11)은 상부 시이트층(10)에 압축 복원성을 부여하고, 또 도액관(15)을 이면측으로부터 지지 보강하고, 도액관(15)이 납작해지거나 개구부(15b)가 변형되는 것을 방지하고 있다. 또, 이 하부 섬유층(11)은 흡수체(4)와 접촉하고 있고, 모세관 작용으로 도액관(15)에 유도되는 체액을 흡수체(4)로 신속히 이행시킬 수 있다. 개구부(15b)에 있어서, 하부 섬유층(11)을 구성하는 일부의 섬유가 도액관(15)속으로 들어가는 일이 있고, 들어간 섬유는 모세관 작용으로 체액을 흡수체(4)로 끌어들이는 효과를 한다.
상부 시이트층(10)에는 용융 취입형 부직포, 예를 들어, 올레핀계·폴리에스테르계·폴리아미드계 등의 열가소성 섬유로 구성되는 평균중량 10-100g/㎡의 용융 취입형 부직포를 사용한다. 용융 취입형 부직포는 일반적으로 섬도가 작은 섬유로 구성되고, 천모양의 유연한 감촉이나 광택이 적은 외관을 쉽게 얻을 수 있다. 이 부직포는 평균중량의 다소, 2차적인 가열 가압처리의 유무 등에 의하여 통기성, 또는 비통기성으로 만들 수 있으나, 그 어느쪽이라도 상부시이트층(10)으로 사용할 수 있다. 용융 취입형 부직포에 도액관(15)을 형성하기 위해서는 부직포 제조 공정에 있어서 용융 취입형 섬유를 소정의 형상의 개구부를 갖는 형판(型板)에 세차게 불어 부형(賦刑)하는 특개평 3-51355호 공보에 개시된 기술을 이용할 수 있다. 이와 같이 형성된 도액관(15)의 하단은 가지런하지가 못하고, 즉, 울통불퉁(요철)하지만 그대로도 좋고, 필요하면 가지런히 정돈하는 가공을 해도 좋다. 하부 섬유층(11)에는 용융 취입형 부직포, 용융 접착형 부직포, 결합제 접착형 부직포, 고속 수류 처리에 의해 섬유가 상호 결합된 부직포 이외에 목적하는 시이트형태를 갖고 있는 단순한 섬유 집적물로서의 웨브등을 사용할 수 있다. 그리고 도액관(15)의 하단이 적어도 하부 섬유층(11)의 표층 내부에 침입하여 개재될 수 있는 정도의 섬유 간극을 갖고 있는 것이 도액관(15)을 보다 확실히 유지시키는 데 있어서 바람직하다.
하부 섬유층(11)에는 일반적인 열가소성 섬유, 예를들어, 섬도 1-10 데닐·평균중량10-40g/㎡, 밀도 0.01-0.1g/㎥의 폴리에틸렌·폴리프로필렌 등의 섬유를 사용할 수 있다. 하부 섬유층(11)에는 체액에 의한 습윤하에서 압축 복원성을 그다지 저하시키지 않는 한 약간의 레이온 등의 친수성 섬유나 또는 표면을 친수화한 폴리에스테르등의 이른바 흡한(吸汗)성 합성 섬유를 혼합할 수가 있고, 또 이것에 의하여 체액의 흡수체(4)로의 이행성을 좋게 도모할 수 있다. 또한 필요하면 하부 섬유층(11)을 공지의 친수화제(표면 활성제)로 처리해도 좋다.
상부 시이트층(10)과 하부 섬유층(11)을 접합시키기 위해서는 고온용융접착제나 기타 접착제·점착제를 개구부(15b)주위나 하부 섬유층(11)에 도포하여 압착하면 되지만, 기타 상부 시이트 층(10)이나 하부 섬유층(11)에 사용한 섬유를 열용융시켜 접합할 수도 있다.
도액관(15)은 그 상단의 개구부(15a)에 있어서 입구직경을 0.2-3㎜, 바람직하게는 0.7-2㎜로 하고, 개구율을 10-70%, 높이를 0.3-5㎜, 또한 하단의 개구부(15b)에 있어서 입구직경을 개구부(15a)의 30-200%의 범위로 억제하는 것이 체액을 흡수체(4)로 조속히 인도하고, 더구나 그 역류를 적게 하는데 바람직하다.
불투액성 이면 시이트(3)에는 폴리에틸렌 시이트를 사용하고, 흡수체(4)에는 분쇄펄프와 고흡수성 폴리머와의 혼합물을 티슈페이퍼로 피복한 것을 사용할 수도 있다.
본 고안에 의한 이면 시이트에서는 도액관을 구비한 용융 취입형 부직포로 이루어진 상부 시이트층에 하부 섬유층을 접합시켜 도액관을 보강했으므로, 도액관이 납작해지지 않으며, 그 선단 개구부는 변형되는 일이 적고 체액의 이행이 빠르며, 더구나 천과 같은 촉감과 외관을 수득할 수 있다.
