TARIFNAME Hipokloröz Asit Solüsyonlari ile Antimikrobiyel Hale Getirilen PolyamidIPolyester Mikrofiber Kompozisyonlari Teknik Alan Bulus; hijyen ve dezenfeksiyon alaninda temizlik bezi, mop bezi, havlu, maske, giysilik vb. kumaslarinda kullanima uygun polyamid/polyester antimikrobiyel mikrofiber kompozisyonlar ve bahsedilen mikrofiber kompozisyonlarin hipokloröz asit solüsyonlari ile antimikrobiyel hale getirilmesini saglamak üzere bir yöntem ile ilgilidir. DESCRIPTION PolyamideIPolyester Made Antimicrobial by Hypochlorous Acid Solutions Microfiber Compositions Technical Area Meet; cleaning cloth, mop cloth, towel, mask, clothing etc. in the field of hygiene and disinfection. Polyamide/polyester antimicrobial microfiber compositions suitable for use in fabrics and antimicrobialization of said microfiber compositions with hypochlorous acid solutions. relates to a method for ensuring that
Teknigin Bilinen Durumu Mikrofiber ipliklerden imal edilen bez, mop ve havlu gibi kumaslar siklikla yüzey temizligi ve dezenfeksiyonu amaci ile kullanilmaktadir. Bu kumaslar özellikle yüzeylerdeki tüm kirleri üzerlerine alarak yüzeyi temizlerler. Ancak yüzeylerine aldiklari mikroorganizmalar birikip çogalarak kötü kokuya sebep olmaktadirlar. Ayrica kontamine olmus bu tür kumaslar, bir baska yüzeye sürüldügünde bu yüzeyi de kirleterek çapraz bulasi riskini artirmaktadir. Tüm bu hususlara yönelik antimikrobiyel mikrofiber ürünler gelistirilmeye çalisilmaktadir. State of the Art Fabrics such as cloths, mops and towels made of microfiber yarns are frequently used for surface cleaning and It is used for disinfection. These fabrics especially remove all the dirt on the surfaces. They clean the surface by taking it on themselves. However, the microorganisms they take on their surfaces accumulate and They multiply and cause bad odour. In addition, such contaminated fabrics When applied to another surface, it also contaminates this surface, increasing the risk of cross contamination. All Antimicrobial microfiber products are being developed for these issues.
Antibakteriyel etkinlik gösteren mikrofiber bezler bazi ülkelerde ticari olarak satilmaktadir. Bu bezlerdeki antibakteriyel etkinlik gümüs iyonlarinin, Iiflerin polyester kismina lif çekimi esnasinda eriyikten katilmasi ve benzer sekilde nanogümüs teknolojisi kullanilarak saglanabilmektedir. Literatürde konu ile ilgili rastlanan basvurulardan bir tanesi CN208301607U numarali faydali modeldir. Ilgili faydali modelde içerisinde barindirdigi gümüs iyonlari araciligiyla bakterileri öldürmek üzere antibakteriyel özellige sahip kendi kendini temizleyen bir temizlik bezi elde edilmesi hedeflenmektedir. Ancak gümüs, agir bir metal olmasi nedeniyle çevresel etkileri hala tartisilmaktadir. Microfiber cloths with antibacterial activity are commercially available in some countries. This antibacterial activity in the cloths, the aspiration of silver ions to the polyester part of the fibers by using the nanosilver technology, and likewise can be provided. One of the references found on the subject in the literature It is utility model numbered CN208301607U. contained in the relevant utility model. It has its own antibacterial properties to kill bacteria through silver ions. It is aimed to obtain a self-cleaning cleaning cloth. However, silver is a heavy Since it is a metal, its environmental effects are still discussed.
Konuyla alakali yapilan arastirma esnasinda 2018 yilinda “Disinfectant Performance of a Chlorine Regenerable Antibacterial Microfiber Fabric as a Reusable Wiper” ile karsilasilmistir. Bu çalismada, bezlerin antibakteriyel hale getirilmesi için, fiberler 3-allyl-5,5- dimethylhydantoin (ADMH) ile asilama polimerizasyonu ile modifiye edilmistir. Modifiye edilen bezler NaOCI-sodyum hipoklorit (çamasir suyu) ile muamele edilerek ADMH'nin üzerindeki N-H baglari N-CI formuna dönüstürülerek antibakteriyel etkinlik saglanmistir. During the research on the subject, in 2018, “Disinfectant Performance of a With “Chlorine Regenerable Antibacterial Microfiber Fabric as a Reusable Wiper” have been compared. In this study, fibers 3-allyl-5.5- modified by grafting polymerization with dimethylhydantoin (ADMH). modified The cloths were treated with NaOCI-sodium hypochlorite (bleach) to reduce ADMH. Antibacterial activity is provided by converting the N-H bonds on the N-CI form.
Bezlerin N-halamin kimyasi kullanilarak antibakteriyel hale getirildigi bu çalismada, ADMH monomeri ile polyester kismi kaplanarak antibakteriyel etkinlik kazandirilmaya çalisilmistir. In this study, in which the diapers were made antibacterial using N-halamine chemistry, ADMH Antibacterial activity was tried to be gained by coating the polyester part with its monomer.
ADMH ile asilama polimerizasyonu oldukça zor ve ticarilesmesi zor bir yöntemdir. Etching polymerization with ADMH is very difficult and difficult to commercialize.
Bir diger çalisma, 2019 yilinda “Rechargeable polyamide-based N-halamine nanofibrous membranes for renewable, high-efficiency, and antibacterial respirators" yapilmistir. Bu çalismada ise polyamid 6, 66 ve 610 solüsyonlarindan nanofiber çekimi yapilarak, hava filtrasyonuna yönelik filtreler üretilmistir. Ayrica üretilen filtreler NaOCI ile muamele edilerek N-H --> N-CI dönüsümü saglanmistir. Ilgili çalismada nanospinning ile üretilmis polyamid yüzeyler, klorlanarak, hava filtrasyonuna yönelik ürünler hedeflenmistir. Nanospinnig ile elde edilen yüzeylerin bez ve havlu gibi mekanik saglamlik gerektiren alanlarda kullanilmasi mümkün olmamaktadir. Another study, “Rechargeable polyamide-based N-halamine nanofibrous” in 2019 membranes for renewable, high-efficiency, and antibacterial respirators". In the study, nanofiber was drawn from polyamide 6, 66 and 610 solutions, air Filters for filtration have been produced. In addition, the filters produced were treated with NaOCI. N-H --> N-CI conversion is provided. In the related study, polyamide produced by nanospinning Surfaces are chlorinated and products for air filtration are targeted. Achieved with nanospinning using the surfaces that require mechanical strength such as cloths and towels. not possible.
N-halamin kimyasi yukaridaki örneklerden de anlasilacagi üzere kisaca; N-H bagina sahip yapilarin bir klor kaynagi ile muamele edilmesi ile N-CI bagina dönüstürülmesini ve N-CI baginin antibakteriyel etkinlik göstermesini içermektedir. Polyamid polimer dogasi geregi -N- H-C=O- baglarini içermektedir. Önemli olan bu baglara ve boyalara zarar vermeden N-H --> N-CI dönüsümünü saglayabilmektir. Bu kapsamda N-halamin kimyasi çalismalarinda çok büyük oranda klor kaynagi olarak NaOCI (sodium hipoklorit) kullanilmaktadir. NaOCI bir yandan N-H baglarini N-CI formuna oldukça yavas dönüstürürken, diger yandan renk agartici ve yüksek pH a bagli olarak polimer Zincirlerini kirici etki gösterebilmektedir. NaOCI nin bu tür dezavantajlarindan dolayi mikrofiber bezlerin kullanma talimatinda “NaOCI kullanmayiniz" gibi ifadeler yer almaktadir. Yine de son kullanicilar bu tür bezleri genellikle 5000 ppm (evsel NaOCI çamasir suyunu 10 kez seyrelterek) NaOCI solüsyonu ile dezenfekte etmeye çal ismaktad irlar. As can be understood from the above examples, the chemistry of N-halamine is briefly; with N-H bond conversion of the structures to N-CI bonds by treating them with a source of chlorine and N-Cl bag contains antibacterial activity. Due to the nature of the polyamide polymer -N- It contains H-C=O- bonds. The important thing is to not damage these bonds and paints N-H --> It is to be able to provide N-CI conversion. In this context, N-halamine chemistry is very important in studies. NaOCI (sodium hypochlorite) is used as a major source of chlorine. NaOCI a On the one hand, it converts the N-H bonds to the N-CI form rather slowly, on the other hand, it bleaches the color. and, depending on the high pH, it can break the polymer chains. This is the NaOCI "Do not use NaOCI" in the instructions for use of microfiber cloths due to such disadvantages. expressions such as However, end-users usually purchase such diapers at 5000 ppm (domestic By diluting the NaOCI laundry water 10 times) to disinfect with the NaOCI solution. they want to play.
