Description
본 발명은 항균성이 우수한 개질 폴리에스테르 스펀본드 부직포으로 보다 구체적으로는 개질 폴리에스테르 섬유 표면에 부착 또는 섬유 내부에 분산된 ZnO 항균제를 포함한 스펀본드 부직포에 관한 것이다. The present invention relates to a modified polyester spunbond nonwoven fabric having excellent antibacterial properties, and more particularly, to a spunbonded nonwoven fabric including a ZnO antibacterial agent attached to the surface of a modified polyester fiber or dispersed in the fiber.
환경의 변화에 따라 인체에 유해한 바이러스, 박테리아 등 인간의 건강을 위협하는 세균, 곰팡이류의 확산으로 이를 효과적으로 차단하고자 하는 노력이 지속되고 있다.Efforts to effectively block the spread of bacteria and fungi that threaten human health such as viruses and bacteria that are harmful to the human body due to changes in the environment are continuing.
각종 섬유류 제품은 사용 또는 보관 불량에 의하여 미생물이 서식하거나, 인체와의 접촉으로 인체의 분비물을 영양원으로 하여 미생물이 서식 및 증식하여 제품에 악취가 발생하고 오염, 변색 등이 발생하여 제품의 내구성,견뢰도 등 품질을 저하시킬 뿐 아니라, 인체의 건강을 위협하게 된다.In various textile products, microorganisms inhabit due to poor use or storage, or microorganisms inhabit and proliferate by using body secretions as nutrients through contact with the human body. It not only deteriorates the quality, such as fastness, but also threatens the health of the human body.
이러한 이유로 인체에 유익한 원적외선 방사, 항균, 대전방지, 자외선 차단, 탈취 및 소취 등의 기능이 부여된 섬유들이 개발 되고 있다.For this reason, fibers with functions such as far-infrared radiation beneficial to the human body, antibacterial, antistatic, UV blocking, deodorizing and deodorizing are being developed.
섬유에 상기 각종 기능성을 부여하는 방법은 크게 후처리 가공법과 원사 개량법으로 나눌 수 있다. 후처리 가공법으로 천연물질에서 염료 성분을 추출하여 항균성을 부여하는 방법과 유기 금속화합물이나 유기물 등의 항균물질을 섬유와 가교 결합시켜 섬유 표면에 열 고정시키거나, 흡착 고정시키는 방법들이 있다. 원사 개량법에는 합성섬유의 제조단계에서 무기계 항균제를 고분자 사이에 혼합 방사시켜 섬유 내부에 함유하는 방법과 항균성을 가지는 유기계 공중합 성분을 만들어 고분자를 합성하는 방법 등이 있다.Methods for imparting the above various functionalities to fibers can be largely divided into post-treatment processing methods and yarn improvement methods. As a post-processing method, there is a method of extracting a dye component from a natural material to impart antibacterial properties, and a method of cross-linking an antibacterial material such as an organometallic compound or organic material with the fiber and heat fixing it to the fiber surface or adsorption fixing method. In the yarn improvement method, there are a method of mixing and spinning an inorganic antibacterial agent between polymers in the manufacturing stage of synthetic fibers to contain it in the fiber, and a method of synthesizing a polymer by making an organic copolymer component having antibacterial properties.
섬유 상에 세균이나 곰팡이의 서식 및 증식을 억제하기 위한 가공은 높은 항균력보다는 어느 수준이상의 항균효과를 지속적으로 유지함과 동시에 인체에 절대적으로 안전하여야 한다. 이러한 의미로 볼 때 후처리 가공법에서 사용된 유기금속 화합물들은 살균성은 매우 우수하나, 독성으로 인하여 인체 안정성 등에 문제가 있다. 또한 이들 유기 금속계화합물들은 섬유와의 접착 및 세탁 내구성 등에 문제가 있어서 항구적 또는 지속적인 항균성을 갖는 데는 한계가 있다.Processing to suppress the inhabitation and proliferation of bacteria or fungi on the fibers should be absolutely safe for the human body while maintaining a certain level of antibacterial effect rather than high antibacterial activity. In this sense, the organometallic compounds used in the post-processing method have excellent sterilization properties, but there is a problem in human safety due to toxicity. In addition, these organometallic compounds have problems such as adhesion to fibers and washing durability, and there is a limit in having permanent or continuous antibacterial properties.
유기계 항균물질은 무기계에 비해 가공이 용이하며, 기계적 물성, 투명도, 색상 등에 큰 영향을 끼치지 않는다는 점에서 현재까지 많이 사용되고 있으나, 앞에서 언급한 바와 같이 항균효과의 지속성이 결여되고 내열성이 열등하다는 점에서 용도가 한정되어 있다. Organic antibacterial substances are easier to process than inorganic substances and are widely used in the sense that they do not significantly affect mechanical properties, transparency, color, etc. use is limited.
또한 천연물질로부터 추출한 염료의 경우 염색단계에서부터 항균성을 부여하는 장점은 있으나 계절적인 제한으로 염료의 추출이 제한적이고, 천연염료의 단점인 견뢰도 증진을 위하여 또 다른 중금속을 이용한 매염염법을 이용해야 한다는 단점이 있다.In addition, in the case of dyes extracted from natural materials, there is an advantage of imparting antibacterial properties from the dyeing stage, but the extraction of the dye is limited due to seasonal restrictions, and a mordant method using another heavy metal must be used to improve the fastness, which is a disadvantage of natural dyes. There is this.
이를 위하여 종래에는 섬유의 제조공정에서 금속 성분을 포함하는 혼합물을 방사하는 방법이 있으나, 이는 제조단가가 높고, 원단 가공시 함유된 금속 성분으로 인하여 제작기계에 무리가 생겨 제조에 어려움이 있다.To this end, there is a conventional method of spinning a mixture containing a metal component in the manufacturing process of the fiber, but this has a high manufacturing cost, and there is a difficulty in manufacturing because the manufacturing machine is burdened due to the metal component contained during the processing of the fabric.
이와 같은 문제점을 해결하기 위한 목적으로, 본 발명에서는 산화아연(ZnO)을 이용한 항균성이 우수한 스펀본드 부직포를 제공하는 데 있다. In order to solve this problem, the present invention is to provide a spunbond nonwoven fabric having excellent antibacterial properties using zinc oxide (ZnO).
또한 본 발명은 항균 첨가제가 인체에 무해하여 마스크, 생리대, 기저귀, 물티슈, 마스크팩 등의 소재 부직포로 사용 가능 스펀본드 부직포를 제공하는 데 있다. In addition, the present invention is to provide a spunbond nonwoven fabric that can be used as a material nonwoven fabric for masks, sanitary napkins, diapers, wet tissues, mask packs, etc., since the antibacterial additive is harmless to the human body.

The modified polyester spunbond nonwoven fabric process of the present invention includes a process of directly spinning a modified polyester resin having an intrinsic viscosity (IV) of 0.9 to 1.5 as a continuous filament, and arbitrarily arranged and laminated to form a web and binding the fibers and a bonding process that stabilizes the shape. Thereafter, it is spun into a continuous filament through a spinning nozzle through a filter device.
이때 항균제인 ZnO Powder를 스펀본드 방사시 수지 투입구에 직접 투입하여 방사시 함유되거나, 또는 개질 폴리에스테르를 Base 수지로 하여 ZnO Powder를 20~60wt% 투입하여 마스터배치로 제조 후 이를 스펀본드 방사시 투입하여 처리할 수 있다. At this time, ZnO Powder, which is an antibacterial agent, is added directly to the resin inlet when spinning and is contained during spinning, or 20~60wt% of ZnO Powder is added as a base resin and ZnO Powder is added to make a masterbatch, and then added when spinning it. can be processed by
방사된 필라멘트는 상이한 냉각챔버로 이동되며 필라멘트는 챔버를 통과할 때 냉각기류가 필라멘트를 가로질러 유입되어 용융된 필라멘트는 고화된다. 스펀본드 부직포의 제조공정에서 연신은 전형적인 섬유방사에 이용되는 고데트방법과 달리 고속기류가 필라멘트에 평행하게 공급되어 개개의 필라멘트를 연신하게 되므로 필라멘트의 냉각과 연신은 단일 공정상에서 이루어지게 된다.The spun filament is moved to a different cooling chamber, and as the filament passes through the chamber, a cooling airflow flows across the filament and the molten filament is solidified. Unlike the godet method used in typical fiber spinning, in the manufacturing process of the spunbond nonwoven fabric, the high-speed airflow is supplied in parallel to the filaments to draw individual filaments, so the cooling and drawing of the filaments are performed in a single process.
이후에 방사된 필라멘트 섬유는 동일한 네트컨베이어에 적층된다. 네트컨베이어 위에서 적층된 부직포층은 캘린더 롤에서 140 내지 160℃로 압착된다. 이 공정에 집속성이 부여되어 한 장의 부직포로 압착된다. 이후에 압착된 부직포는 권취기에 감겨 제조 공정이 끝이 난다. Afterwards, the spun filament fibers are stacked on the same net conveyor. The nonwoven fabric layer laminated on the net conveyor is compressed at 140 to 160°C in a calender roll. In this process, bundling properties are imparted and compressed into a single sheet of nonwoven fabric. After that, the compressed nonwoven fabric is wound on a winder to complete the manufacturing process.
상기 압착된 부직포 시트는 평균 직경이 10 ~ 40㎛인 섬유로 이루어지고, 단위면적당 중량은 10 ~ 100g/㎡이다. 또한, 인장강도는 1 ~ 10㎫이며 하중은 0.1 ~ 10Kgf인 것을 특징으로 한다.The compressed nonwoven sheet is made of fibers having an average diameter of 10 to 40 μm, and a weight per unit area is 10 to 100 g/m 2 . In addition, it is characterized in that the tensile strength is 1 to 10 MPa and the load is 0.1 to 10 Kgf.
본 발명 부직포의 흡수율은 190 내지 200% 이상이 적당하며, 바람직하게는 2000% 이상이 적당하다. The water absorption of the nonwoven fabric of the present invention is suitably 190 to 200% or more, preferably 2000% or more.
