To a long-fiber spunbond nonwoven fabric capable of reducing revolutions per minute and remarkably improved in urine leakage when using sanitary materials and diapers through optimization of the content of hydrophilic polymer applied to the final nonwoven fabric and its manufacturing method.
종래로부터 부직포는 그 물리화학적 특성을 변형하여 다양한 분야, 예를 들어 위생용, 의료용, 농업용 또는 산업용과 같은 분야에서 다양한 용도로 사용되어 오고 있으며, 특히 근래 들어 생활수준이 향상됨에 따라 위생용품의 하나인 흡수성 물품, 예를 들어 기저귀 또는 생리대와 같은 위생재용 부직포로 일반 생활 속에서 다양하게 사용되고 있는데, 이러한 위생재용 부직포는 그 용도에 부응하여 친수화 처리를 요하는 경우가 대부분인데, 이러한 친수화 처리 공정은 장섬유 스펀본드 부직포를 생산하는 데 있어 가장 기본적으로 적용되는 후가공 기술 중에 하나로, 이러한 친수처리 부직포는 유아 및 성인의 신체에 직접적으로 접촉되는 일회용 위생소재의 안감으로는 물론 멀칭용, 못자리용 등의 농업용 소재와 루핑용, 하우스랩용 등으로도 사용될 수 있을 것이다.Conventionally, nonwoven fabrics have been used for various purposes in various fields, such as hygiene, medical, agricultural or industrial use, by modifying their physicochemical properties, and in particular, as living standards improve in recent years, it is one of hygiene products. Phosphorus absorbent articles, for example, nonwoven fabrics for sanitary materials such as diapers or sanitary napkins, are used in various ways in general life. In most cases, these nonwoven fabrics for sanitary materials require hydrophilization treatment according to the use, such hydrophilization treatment The process is one of the most basic post-processing technologies applied to the production of long fiber spunbond nonwovens. This hydrophilic nonwoven fabric is used as a lining for disposable sanitary materials that come into direct contact with the body of infants and adults, as well as for mulching and nails. It may also be used for agricultural materials such as roofing, house wrap, etc.
이와 같이, 종래의 부직포에 친수제를 처리하는 방법은 다양하게 개시되어 있는데, 예를 들어 대한민국 특허출원 제2006-0018133호에서는, "친수형 복합장섬유로 이루어진 웹을 적층하여 결합한 부직포에 있어서, 상기 친수형 복합장섬유는 친수성 중합체가 소수성 중합체를 섬유의 길이방향으로 둘러싼 형태로 시스 앤드 코아형의 형태로 구성되고, 상기 친수형 복합장섬유가 방사형 웹(web)에 엠보싱형으로 결합ㆍ고정되어 형성됨을 특징으로 하는 내구친수성이 향상된 복합장섬유 방사형 부직포"를 개시하고 있으며, 대한민국 특허공개공보 제2006-0116897호에서는, "부직포의 친수 처리시 부분적으로 친수유제를 차단하는 차단막을 이용하되 회전롤러(Kiss roll)에 의한 친수제 도포 방식의 경우에는 필름 형태의 차단막을 부분적으로 롤러 상부에 위치시키고, 분산시키는 방법으로 친수제를 도포하는 경우에는 판 형태의 차단막을 친수제 분산 장치의 분사 노즐 앞에 부분적으로 위치시켜 부분적으로 친수처리되도록 함으로서 전체적으로 친수 가공된 부직포를 기저귀 등에 사용시 유체가 수평방향으로 이동되기 때문에 유체가 기저귀 등의 시스템을 벗어나 누수되는 문제점을 용이하게 방지할 수 있도록 한 부분 친수성 장섬유 스판본드 부직포의 제조 방법"을 개시하고 있으며, 대한민국 특허공개공보 제2015-0057061호에서는, "용융가소성 수지를 용융시킨 후 다수개의 오리피스로 압출시켜 필라멘트를 형성시키고, 필라멘트를 냉각하고 연신한 후 웹을 형성하여 결합처리된 한 층 이상의 스펀본드 부직포의 제조방법에 있어서, 상기 스펀본드 부직포는 고농도 친수제 에멀젼의 미립자화를 통해 부직포 웹과의 표면결합력을 증대시켜 균분산성을 확보할 수 있는 연속 순환식 초음파분산 시스템을 도입하여 부직포 웹에 친수제를 균일하게 도포하여 제조하는 단계를 포함함을 특징으로 하는 균일한 친수성이 발현되는 장섬유 스펀본드 부직포의 제조방법"을 개시하고 있다.As such, there are various methods for treating a hydrophilic agent on a conventional nonwoven fabric. For example, in Korean Patent Application No. 2006-0018133, "In a nonwoven fabric in which a web made of a hydrophilic composite long fiber is laminated and bonded, The hydrophilic composite long fiber is composed of a sheath and core type in a form in which a hydrophilic polymer surrounds a hydrophobic polymer in the longitudinal direction of the fiber, and the hydrophilic composite long fiber is bonded and fixed to a radial web in an embossed type. Disclosed is a composite long fiber spinning nonwoven fabric with improved durability and hydrophilicity, characterized in that it is formed through In the case of applying the hydrophilic agent by a roller (kiss roll), a film-type barrier film is partially placed on the upper part of the roller, and when the hydrophilic agent is applied by dispersing, the plate-shaped barrier film is a spray nozzle of the hydrophilic agent dispersing device. Partially hydrophilic field made to be partially located in front so that it is partially hydrophilicized, so that when using a non-woven fabric that is entirely hydrophilic in diapers, etc., the fluid moves in the horizontal direction, so that the problem of fluid leaking out of the system such as the diaper can be easily prevented. A method of manufacturing a fiber spunbond nonwoven fabric is disclosed, and in Korean Patent Publication No. 2015-0057061, "a melt plastic resin is melted and extruded into a plurality of orifices to form a filament, and after cooling and stretching the filament In the method for manufacturing one or more layers of spunbond nonwoven fabric bonded by forming a web, the spunbond nonwoven fabric is continuous capable of securing uniform dispersibility by increasing the surface bonding force with the nonwoven web through fine particle formation of a high-concentration hydrophilic emulsion. Disclosed is a "method for producing a long fiber spunbond nonwoven fabric exhibiting uniform hydrophilicity," comprising the step of uniformly applying a hydrophilic agent to a nonwoven web by introducing a circulating ultrasonic dispersion system.
그런데, 상기한 방법에 따라 친수처리한 부직포, 특히 위생용으로 사용되는 부직포는 친수처리된 부직포 내(內) 탈락된 친수제가 소수성 부직포로 전이되면서 배뇨액, 체액이 누출(leakage)되어 불편을 야기하거나 각종 오염원으로부터 노출되기 쉬어 사용자의 편의성이 떨어지는 문제점이 있다.However, in the nonwoven fabric treated with the hydrophilicity according to the above method, especially the nonwoven fabric used for hygiene, the hydrophilic agent dropped from the hydrophilic treated nonwoven fabric is transferred to the hydrophobic nonwoven fabric, and urine and body fluids leak, causing inconvenience In addition, there is a problem in that the user's convenience is deteriorated because it is easy to be exposed from various pollutants.
이에 본 발명자 등은 상기한 문제점을 해결하기 위해 예의 연구한 결과, 부직포에 처리된 친수제 함량(wt%)이 높을수록 소수성 부직포로 친수제가 전이되고 탈락될 확률이 높아지기 때문에 최적함량 설정이 중요하다는 것을 인지하였으며, 또한 종래의 기술에서 사용하고 있는 친수제는 낮은 습윤(wetting)성으로 친수 코팅 공정시 키스롤(Kiss-roll) rpm을 과도하게 가동해야하는 문제점이 있었으며, 이는 결국 누출(leakage) 원인이 되고 있음을 인식하고, 이를 해결할 수 있는 방법을 제시하여 본 발명을 완성하게 되었다.Accordingly, the present inventors have studied diligently to solve the above problems, and as a result, the higher the content (wt%) of the hydrophilic agent treated in the nonwoven fabric, the higher the probability that the hydrophilic agent is transferred to the hydrophobic nonwoven fabric and is dropped. Therefore, setting the optimal content is important. In addition, the hydrophilic agent used in the prior art had a problem in that the kiss-roll rpm was excessively operated during the hydrophilic coating process due to low wetting properties, which eventually caused leakage Recognizing that this is being done, the present invention was completed by suggesting a method to solve this problem.
따라서, 본 발명은 상기한 종래의 실정을 감안하여 된 것으로서, 본 발명의 제일 목적은 소수성의 특성을 띄는 폴리프로필렌에 습윤성이 향상된 친수제 적용하여 친수성 부직포를 제조함에 있어 습윤성이 향상된 친수제를 사용하여 친수코팅 방식 rpm을 15% 절감이 가능하고 최종 부직포에 도포되는 친수 고분자 함량 최적화를 통해 소수성 부직포로 친수제가 전이되고 탈락될 확률을 최소화함으로 위생자재 및 기저귀 사용시 배뇨 누수 현상이 개선된, 전이 안정성이 우수한 친수성 장섬유 스펀본드 부직포를 제공하기 위한 것이다.Therefore, the present invention was made in view of the above-described conventional situation, and the first object of the present invention is to use a hydrophilic agent with improved wettability in manufacturing a hydrophilic nonwoven fabric by applying a hydrophilic agent with improved wettability to polypropylene having hydrophobic properties. Thus, it is possible to reduce the rpm of the hydrophilic coating method by 15%, and by optimizing the content of the hydrophilic polymer applied to the final nonwoven fabric, the probability of the hydrophilic agent being transferred to the hydrophobic nonwoven fabric and falling off is minimized. It is to provide this excellent hydrophilic long-fiber spunbond nonwoven fabric.
