Description

TARIFNAME KONTROLLÜ KOKU SALIM MEKANIZMASINA SAHIP BIR HIJYEN Teknik Alan Bu bulus, bebek bezi, hijyenik ped, külot bez, hasta bezi, alistirma külodu vb. hijyen ürünlerinde kullanim sonrasi olusan kötü kokularin önlenebilmesi için, hijyen ürününün emici core tabakasi içerisinde kontrollü koku salim mekanizinasina sahip özel gelistirilmis mikro tanecikler ile ilgilidir. Önceki Teknik Koku, insanin hayat kalitesini dogrudan etkilemektedir. Koku terapi için idealdir. Ortamdaki olumsuz enerjileri temizler, metabolizmayi dengeler. Günümüzde koku ile tedavi yöntemleri oldukça revaçtadir. Türk tip tarihinde Ibn-i Sina ve Biruni gibi ünlü tip âlimleri, birçok bitki ve kokusunun hastaliklari önleyici ve giderici oldugunu söylemis ve hastalar üzerinde uygulamislardir. Kötü kokular sosyal iliskileri, insanlar arasi iletisimi olumsuz etkiler. Bunlar ayak kokusu, ter kokusu, kirli bebek bezi vb. kokulardir. Insanlar bu kokulardan kurtulabilmek veya bu kokulari gizleyebilmek için çesitli metotlar gelistirmislerdir. Günümüzde kullanicinin konfor ve güvenligini olumlu yönde etkileyen fonksiyonel özellikli ve katma degeri yüksek ürünlere olan ilgi artmaktadir. Bu ürünlere bir örnek de kullanim sonrasi olusan kötü koku olusumunu önleyen hijyen ürünleridir. Mikrokapsülasyon herhangi bir çekirdek materyalinin, dis etkenlerden korunmasi amaciyla dogal veya sentetik polimer duvar materyali içerisine kapsüllenmesidir. Mikrokapsüller, boyutlari 1 ile 100 um arasinda degisen, çekirdek ve duvar maddesinden olusan partiküllerdir. Kapsüller boyutlarina göre mikrokapsül yaninda makrokapsül veya nanokapsül olarak da isimlendirilebilmektedirler. Mikrokapsüller, çok uzun yillardir kozmetik, tip, farmokoloji, gida vb. çok farkli alanlarda kullanilmaktadir. Mikrokapsülasyon sayesinde çekirdek materyal reaktif, korozif ve zararli çevreden korunabilmekte, daha iyi islenebilirlik kazanabilmekte (Çözünürlügün, akiskanligin artmasi V.b.), raf ömrü artmakta, tehlikeli ve toksik materyaller güvenli bir sekilde tasinabilmekte, enzim ve mikroorganizma immobilizasyonu gerçeklestirilebilmekte, tat ve kokular gizlenebilmekte, sivi maddeler kati halde tasinabilmekte ve salimi kontrol altinda tutulabilmektedir. dokümaninda, bebek bezinin en dis katmani olan backsheet yüzeyinde veya bebek bezi emici core katmaninda kullanilan SAP (super emici polimerler) yapisinda bulunan parfüm içerikli mikro koku tanecikleri üzerine çalismalar yapilmaktadir. Bir çalismada bebek bezinin cilde temas eden en üst katmani olan topsheet tabakasinda kesikli veya sürekli losyon kullanimi ile cildin yüzey enerjisini degistirerek Cilt ve kaka arasinda bariyer olusturdugu iddia edilmistir. Bu losyon içerisinde kremi olusturan petrolatum ve mineral yaglar gibi hammaddeler, kremi sabitleyici ajanlar, hidrofilik sürfaktanlar bulunmaktadir. Bu hammaddeler de içerisinde su, viskozite ayarlayici, parfüm, antiseptik dezenfektan, farmasötik aktif maddeler, film olusturucular, deodorantlar, opaklastiricilar, stabilizatörler ve çözücü maddeler içermektedir. Bu bilesimden olusan losyon, topsheet (bezin cilde temas eden en üst katmani) yüzeyine spreyleme veya losyona dardirma metodu ile uygulanmaktadir. Topsheet7e uygulanmis losyon direkt temasla, bebegin hareketleriyle veya bebegin vücut isisiyla cilde ulasmaktadir. Bünyesinde bulunan pariüm sayesinde de bezin güzel kokmasi saglanmaktadir. dokümaninda, benzer sekilde losyon uygulamasi topsheet ve leg cuff (bacak bariyerleri) hammaddelerine uygulanarak losyonun bebegin cildine direkt temasla, bebegin hareketleriyle veya cilt isisiyla temas ettigi iddia edilmistir. Leg cuff`a uygulanan losyon ile beraber bir önceki çalismadan daha genis bir cilt koruyucu alanin varligi iddia edilmistir. Teknikte yer alan, EP0957869B1 referans numarali Avrupa patent dokümaninda, bebek bezinin bebegin cildine temas etmeyen en dis katmani olan backsheet hammaddesine , içerisinde parfüm içeren mikroküreler yerlestirilmistir. Bebegin hareket etmesi ile mikrokapsül yüzeyinde shear force olusur, bu sayede mikroküreler mekanik olarak parçalanarak içerisindeki parfüm kokusunu disariya vermektedir. Burada bezde olusan kullanim sonrasi kötü kokuyu engellemek için koku emme özelligine sahip zeolitler, aktiflestirilmis karbonlar kötü kokuyu maskelerken ayni zamanda kontrollü koku salinimi ile içerisindeki parfümü salmaktadir. Teknikte yer alan, WO98/51248 referans numarali uluslararasi patent dokümaninda, bebek bezi ve alistirma külodu ürünlerinde bezin en dis katmanini olusturan backsheet°in dis yüzeyi ve baeksheet hammaddesinin en disinda nefes alan nonwoven (dokumasiz kumas) arasina yapistirici içeren baglayici bir eleman ile yerlestirilen mikrokapsül tanecikleri kullanilmistir. Backsheetün nefes alan dis yüzeyine dokunuldugu zaman kotrollü koku salim mekanizmasina sahip parfüm içeren mikrotaneciklerin patlayarak içerisindeki parfümü disari saldigi iddia edilmistir. Teknikte yer alan, WO98/25562 Al referans numarali uluslararasi patent dokümaninda, bezin en dis katmanini olusturan baksheet`in bir veya birden fazla parfüm bölgeleri içerdigi, bu parfüm bölgelerinde baglayici yardimiyla bir veya birden fazla farkli tipte parfüm içeren mikrotaneciklerin backsheet'in dis yüzeyine tutturuldugu ve bir çekme bandi ile diger yüzeyinin kaplandigi açiklanmistir. Çekme bandi söküldügünde veya yirtildiginda mikrotaneciklerin de patlayarak içerisindeki parfümü disari saldigi ve/veya kötü kokuyu bünyesinde hapsettigi iddia edilmistir. Hijyen ürünlerinde kullanim sonrasi etrafa yayilan kötü kokunun bastirilmasi, yaygin olarak bünyesinde barindirdigi losyonun veya kremin parfümü ile saglanmaktadir. Bununla birlikte, kullanilan losyon/kremler, özellikle hassas bebek cildinde irritasyona sebep olabilmekte, bebek bezinin emicilik kapasitesini düsürmekte, emme zamanini geciktirmekte ve cilde geri verilen islaklik miktarini artirmaktadir. Mevcut teknolojiler ile üretilen hijyen ürünlerinde losyonun topsheet"e uygulanmasi, içerisinde bulunan parfüm nedeniyle kullanici cildinde tahrise sebep olabilmektedir. Ayni zamanda uygulanan bu losyon, hijyen ürününü olusturan NW yüzeylerdeki (dokumasiz kumas yüzeyi) sivi geçis yollarini tikayarak kapiler gradyanin azalmasina neden olmakta ve yüzeyin hidrofilik özelligini olumsuz etkilemektedir. Bu durum hijyen ürününün ana perforinans kriterleri olan emme zamani ve rewet (cilde geri verilen islaklik miktari) performanslarini düsürmektedir. Dolayisiyla hijyen ürününün idrari daha geç sürede emmesi, ciltte uzun süre islaklik kalmasina bagli olarak sizma ve pisik problemleri ile karsilasilma olasiligi artmaktadir. Buna ek olarak, hijyen ürününün backsheet tabakasinda parfüm içeren mikrotaneciklerin kullaniminda, mikrotaneciklerin hijyen ürününün idrar, kan gibi vücut sivilari kokan iç kismina uzak konumlandirilmasi nedeniyle, kullanim sonrasi emici core tabaka içerisinde süper emici polimerler bünyesinde hapsedilen vücut sivisi kokusunu bastirmada zayif kalmaktadir. Ayrica mekanik baski etkisiyle mikrokürelerin yüzeyinde shear force olusturularak, kürenin yüzeyinin yirtilip parfümün serbest kalmasi islemi, kullanici otururken, uyurken, kosarken, oynarken gibi hareket halinde oldugu durumlarda sürekli aktif hale geldigi için çogu zaman hijyen ürünü, bir vücut sivisi ile karsilasmadan, koku salim islemi gerçeklesmektedir. Hijyen ürününün vücut sivisi ile karsilastigi durumda ise, artik mikrokapsül içerisindeki parfüm zaten salinmis oldugundan, olusan kötü kokuyu bastirmasini bekledigimiz parfümün koku yogunlugu hijyen ürününde azalmis olur. Bu da ilgili hijyen ürünü için, vücut sivisi ile karsilasma sonrasi olusan kötü kokunun bastirilmasinda yetersiz kalmasina neden olur. Bulusun Kisa Açiklamasi Bu bulus ile birlikte kullanici cildine zarar vermeden koku hapsetme ve kontrollü koku salim mekanizmasina sahip bir hijyen ürünü gelistirilmistir. Bulus ile kritik performans parametreleri olan Vücut sivisini emme süresi iyilestirilmis, Cilde geri verilen islaklik miktari artirilmadan koku hapsetme ve kontrollü koku salim mekanizmasina sahip bir hijyen ürünü gelistirilmistir. Bulus ile emicilik kapasitesi düsürülmeden koku hapsetme ve kontrollü koku salim mekanizmasina sahip bir hijyen ürünü gelistirilmistir. Bulusun Ayrintili Açiklamasi Bu bulus amacina ulasmak için gerçeklestirilen bir hijyen ürünü ; - kötü kokunun minimum degisiklikle yakalanmasi, - kötü kokunun tutulmasi/hapsedilmesi, - mikrokapsül içerisindeki parfîimün çevreden korunmasi, - istenen durumda parfümün kapsülün disina salinmasi basamaklarindan olusan kontrollü koku salim/hapsetme mekanizmasina sahiptir. Mikrokapsüllerin, matriks tipi suda çözünebilen kapsüller ve kabuk tipi suda çözünmeyen kapsüller olmak üzere çesitleri bulunmaktadir. Matriks tipi suda çözünebilen koku kapsülleri kuru toz formunda nisasta kapsüllerinden olusmaktadir ve biyobozunur özelliktedirler. Nem ile karsilastiklari zaman yavas yavas difüzyon baslamaktadir. Vücut sivisi ile karsilastiktan sonra ise partüm salinimi gerçeklesmektedir. Kabuk tipi suda çözünmeyen kapsüller ise melamin, siklodekstrin ve kitosan gibi polimerler içennekte olup, suda dagitilabilir özellige sahiplerdir. Nem ile karsilastiginda kabuk boyunca yavas bir difüzyon gerçeklesmektedir. Mekanik gerilim altinda kabugun kirilmasi sonrasi ise koku saliniini gerçeklesmektedir. Koku kontrollü salim mekanizmasina sahip mikrokapsüller, hijyen ürünlerinde SAP (süper absorban polimer) polimerinin selüloz ile kanstirildigi asamada, selüloz tabakasina, yani bezin core tabakasina uygulanmaktadir. Salinan partümün miktari mikrokapsül boyu ve duvar kalinligina; kullanilan partümün tipi ve miktari ise, mikrokapsüllerin parçalanma gücüne, mikrokapsül miktarina ve dagilimina göre degismektedir. Mikrokapsül miktari bez adedi basina 2-80 mg, tercihen 5-70 mg, daha yaygin olarak 20-50 mg kullanilmaktadir. Mikrokapsüllerin ortalama partikül boyutu matriks tipi suda çözünebilen kapsüller için genellikle 150 !im den küçüktür, tercihen 100 um den küçük, daha yaygin olarak 75 pm den küçüklerdir. Kabuk tipi suda çözünmeyen mikrokapsüllerin ortalama partikül boyu ise matriks tipi olanlara göre daha küçük olup 2-50 mm araligindadir, tercihen 5-40 um, daha yaygin olarak 10-20 um kullanilmaktadir. Kullanilan mikrokapsüllerin koku içerigi orani %20`den büyüktür, tercihen %35 ve daha yaygin olarak %40 dan büyük olmasi tercih edilir. Mikrokapsüllerin emici core tabaka içerisindeki dagilimi, kullanilan süper emici polimerlerin dagilimina göre ayarlandiginda koku absorplama ve salinim mekanizmalari daha etkin kullanilmis olmaktadir. Homojen dagilima sahip emici tabakalarda mikrokapsüllerin homojen dagilimi istenirken, emici tabakanin farkli bölgelerinde farkli oranlarda SAP ve pulp içeren tasarim için kullanilan mikrokapsüllerin dagilimi da farklilik göstermektedir. Ön ve orta bölgelerinde daha fazla SAP ve pulp karisimi içeren bezler için; ön ve orta bölgede kullanilan mikrokapsül miktari, emici core tabakanin bütününde bulunan mikrokapsül miktarinin %55-90"1 arasinda, tercihen %60-85 "i, daha yaygin olarak %65-70"ini olusturur. Bu durumda bezin arka kisminda kullanilan mikrokapsül miktari da %10-45 arasinda, tercihen Parfüm içeren mikrotaneciklerin emici core tabakada kullanimi ile vücut sivisinin bu tabakaya ulasmasi aninda, kötü koku absorplama mekanizmasi Çalismaya baslar. Kullanilan mikrotaneciklerin emici core tabakayi olusturan SAP ve pulp karisiminin bölgesel yogunluguna göre ayarlandigindan, kötü kokunun absorplanmasi literatürdeki diger yöntemler ile kiyaslandiginda daha üstün performans göstermektedir. Parfümün cilt ile direkt temasinin engellenmis olmasi ciltte kizariklik, tahris, pisik olusuinunu minimuma indirmektedir. TR TR TR DESCRIPTION A HYGIENE WITH CONTROLLED ODOR RELEASE MECHANISM Technical Field This invention is used for baby diapers, sanitary pads, panty diapers, sick diapers, training pants, etc. It is related to specially developed micro particles with a controlled odor release mechanism within the absorbent core layer of the hygiene product in order to prevent bad odors occurring after use in hygiene products. Prior Art Odor directly affects human quality of life. Ideal for scent therapy. It clears negative energies in the environment and balances the metabolism. Nowadays, scent treatment methods are very popular. In the history of Turkish medicine, famous medical scholars such as Ibn-i Sina and Biruni said that many plants and their scents prevent and cure diseases and applied them on patients. Bad odors negatively affect social relations and communication between people. These are foot odor, sweat odor, dirty diaper, etc. are smells. People have developed various methods to get rid of or hide these odors. Nowadays, there is an increasing interest in products with functional features and high added value that positively affect the comfort and safety of the user. An example of these products is hygiene products that prevent the formation of bad odors after use. Microencapsulation is the encapsulation of any core material into a natural or synthetic polymer wall material to protect it from external factors. Microcapsules are particles consisting of core and wall material, varying in size from 1 to 100 μm. Capsules can be called microcapsules, macrocapsules or nanocapsules depending on their size. Microcapsules have been used in cosmetics, medicine, pharmacology, food, etc. for many years. It is used in many different areas. Thanks to microencapsulation, the core material can be protected from reactive, corrosive and harmful environments, it can gain better processability (increasing solubility, fluidity, etc.), its shelf life increases, hazardous and toxic materials can be transported safely, enzyme and microorganism immobilization can be achieved, tastes and odors can be hidden, liquid substances can be stored. It can be transported in solid form and its release can be kept under control. In the document, studies are carried out on the perfume-containing micro odor particles found in the SAP (super absorbent polymers) structure used on the backsheet surface, which is the outermost layer of the diaper, or in the absorbent core layer of the diaper. In a study, it was claimed that intermittent or continuous use of lotion on the topsheet layer, which is the top layer of the diaper in contact with the skin, creates a barrier between the skin and poop by changing the surface energy of the skin. This lotion contains raw materials such as petrolatum and mineral oils that make up the cream, cream fixing agents, and hydrophilic surfactants. These raw materials include water, viscosity adjuster, perfume, antiseptic disinfectant, pharmaceutical active ingredients, film formers, deodorants, opacifiers, stabilizers and solvents. The lotion consisting of this composition is applied to the surface of the topsheet (the top layer of the cloth in contact with the skin) by spraying or dipping into the lotion. The lotion applied to Topsheet7 reaches the skin through direct contact, the baby's movements or the baby's body temperature. Thanks to the perfume it contains, the diaper smells nice. In the document, it is claimed that the lotion comes into contact with the baby's skin through direct contact, the baby's movements or skin temperature, by applying lotion similarly to topsheet and leg cuff (leg barriers) raw materials. It has been claimed that the lotion applied to the leg cuff provides a larger skin protective area than the previous study. In the European patent document with reference number EP0957869B1, microspheres containing perfume are placed in the backsheet raw material, which is the outermost layer of the diaper that does not come into contact with the baby's skin. When the baby moves, shear force occurs on the surface of the microcapsule, thus the microspheres break apart mechanically and release the perfume scent inside. Here, in order to prevent the bad odor occurring in the diaper after use, zeolites and activated carbons, which have odor absorbing properties, mask the bad odor and at the same time release the perfume inside with controlled odor release. In the international patent document with reference number WO98/51248 in the technique, the microcapsule is placed with a binding element containing adhesive between the outer surface of the backsheet, which forms the outermost layer of the diaper in baby diaper and training pants products, and the breathable nonwoven (non-woven fabric) at the outermost layer of the baeksheet raw material. particles were used. It has been claimed that when the breathable outer surface of the backsheet is touched, microparticles containing perfume with a controlled scent release mechanism explode and release the perfume inside. In the international patent document with reference number WO98/25562 Al in the technique, it is stated that the backsheet, which forms the outermost layer of the diaper, contains one or more perfume regions, and microparticles containing one or more different types of perfume are attached to the outer surface of the backsheet with the help of a binder in these perfume regions. and it has been explained that the other surface is covered with a tensile band. It has been claimed that when the pulling tape is removed or torn, the microparticles explode and release the perfume inside and/or trap the bad odor within it. Suppression of the bad odor spread after use in hygiene products is commonly achieved by the perfume of the lotion or cream it contains. However, the lotions/creams used can cause irritation, especially on sensitive baby skin, reduce the absorbent capacity of the diaper, delay the sucking time and increase the amount of wetness returned to the skin. Applying the lotion to the topsheet in hygiene products produced with current technologies may cause irritation on the user's skin due to the perfume it contains. At the same time, this lotion applied blocks the liquid passageways on the NW surfaces (non-woven fabric surface) that constitute the hygiene product, causing the capillary gradient to decrease and the hydrophilic effect of the surface. This situation reduces the absorption time and rewet (amount of wetness returned to the skin) performances, which are the main perforinance criteria of the hygiene product. Therefore, the possibility of the hygiene product absorbing urine in a slower time and encountering leakage and rash problems due to long-term wetness on the skin increases. In addition, when microparticles containing perfume are used in the backsheet of the hygiene product, they are weak in suppressing the odor of body fluid trapped in the super absorbent polymers in the absorbent core layer after use, since the microparticles are positioned away from the interior of the hygiene product, which smells of body fluids such as urine and blood. In addition, by creating shear force on the surface of the microspheres with the effect of mechanical pressure, the process of tearing the surface of the sphere and releasing the perfume is constantly activated when the user is in motion such as sitting, sleeping, running, playing, etc. is happening. In the case where the hygiene product encounters body fluid, since the perfume in the microcapsule has already been released, the odor intensity of the perfume, which we expect to suppress the bad odor, decreases in the hygiene product. This causes the relevant hygiene product to be insufficient in suppressing the bad odor that occurs after encountering body fluid. Brief Description of the Invention With this invention, a hygiene product with odor trapping and controlled odor release mechanism without harming the user's skin has been developed. With the invention, the body fluid absorption time, which is critical performance parameters, has been improved, and a hygiene product with odor trapping and controlled odor release mechanism has been developed without increasing the amount of wetness returned to the skin. With the invention, a hygiene product with odor trapping and controlled odor release mechanism without reducing the absorbency capacity has been developed. Detailed Description of the Invention: A hygiene product designed to achieve the purpose of this invention; It has a controlled odor release/imprisonment mechanism consisting of the steps of - capturing the bad odor with minimum change, - retaining/imprisoning the bad odor, - protecting the perfume in the microcapsule from the environment, - releasing the perfume out of the capsule when desired. There are different types of microcapsules: matrix type water-soluble capsules and shell type water-insoluble capsules. Matrix type water-soluble fragrance capsules consist of starch capsules in dry powder form and are biodegradable. When they encounter moisture, diffusion begins slowly. After encountering body fluid, partum is released. Shell-type water-insoluble capsules contain polymers such as melamine, cyclodextrin and chitosan and have water-dispersible properties. When it encounters moisture, a slow diffusion occurs throughout the shell. The odor is released after the shell breaks under mechanical tension. Microcapsules with odor-controlled release mechanism are applied to the cellulose layer, that is, the core layer of the diaper, at the stage where the SAP (super absorbent polymer) polymer is mixed with cellulose in hygiene products. The amount of released partum depends on microcapsule length and wall thickness; The type and amount of partum used varies depending on the disintegration power of the microcapsules, the amount of microcapsules and their distribution. The amount of microcapsules is 2-80 mg, preferably 5-70 mg, more commonly 20-50 mg per number of glands. The average particle size of microcapsules is generally less than 150 µm for matrix-type water-soluble capsules, preferably less than 100 µm, more commonly less than 75 µm. The average particle size of shell type water-insoluble microcapsules is smaller than matrix type ones and is in the range of 2-50 mm, preferably 5-40 μm, 10-20 μm is more commonly used. It is preferred that the odor content of the microcapsules used is greater than 20%, preferably greater than 35% and more commonly greater than 40%. When the distribution of microcapsules in the absorbent core layer is adjusted according to the distribution of the superabsorbent polymers used, odor absorption and release mechanisms are used more effectively. While homogeneous distribution of microcapsules is desired in absorbent layers with homogeneous distribution, the distribution of microcapsules used for designs containing different amounts of SAP and pulp in different parts of the absorbent layer also varies. For glands containing more SAP and pulp mixture in the front and middle regions; The amount of microcapsules used in the front and middle region constitutes between 55-90%, preferably 60-85%, more commonly 65-70%, of the amount of microcapsules in the entire absorbent core layer. In this case, the amount of microcapsules used in the back part of the diaper With the use of microparticles, preferably containing perfume, between 10-45% in the absorbent core layer, the moment the body fluid reaches this layer, the bad odor absorption mechanism starts to work, as the microparticles used are adjusted according to the regional density of the SAP and pulp mixture that forms the absorbent core layer. It shows superior performance compared to other methods. Preventing direct contact of the perfume with the skin minimizes skin redness, irritation and rash.
