Abstract

U današnjem svijetu sve je veća potreba za tekstilnim materijalima (proizvodima), koji imaju dobra antimikrobna svojstva. Mikroorganizmi na tekstilnim materijalima nisu poželjni jer izazivaju neugodne mirise, gubitak čvrstoće, skupljanje prljavštine zbog čega smanjuju funkciju i estetski izgled tekstilnog materijala. Kod ljudi mogu izazvati razne zdravstvene tegobe. Zbog toga se od antimikrobnih sredstava očekuje da unište što veći broj mikroorganizama a da pritom ne ugroze ljudsko zdravlje, te duga postojanost na tekstilnom materijalu bez narušavanja izgleda i svojstava tekstilnog proizvoda, te ekološka i ekonomska prihvatljivost. Za potrebe istraživanja upotrebljeno je ulje iz ekstrakta biljke Nim koji je priređen u obliku otopine definirane koncentracije i u definiranom omjeru se koristio za obradu pletiva. Uzorci su prethodno obrađeni plazmom u prisustvu kisika ili argona u definiranim uvjetima, nakon čega je provedena obrada iscrpljenjem kupelji pomoću raspršivanja na materijal pneumatskom pumpom. Nakon obrade provedena je analiza provedena je analiza makro strukture uzoraka primjenom USB mikroskopa Dino-lite, mikromorfološka analiza korištenih uzoraka od pamuka i modalnih vlakana primjenom FE-SEM mikroskopa, te analiza antimikrobne učinkovitosti mikrokapsuliranog eteričnog ulja Nima primjenom kvalitativnog mikrobiološkog testa.

Abstract (english)

In today's world, there is an increasing need for textile materials (products) that have good antimicrobial properties. Microorganisms on textile materials are not desirable because they cause unpleasant odors, loss of strength and accumulation of dirt, which affect the function and esthetic appearance of the textile material. They can cause various health problems in people. Therefore, antimicrobial agents are expected to kill as many microorganisms as possible without endangering human health, to remain on the textile material for a long time without affecting the appearance and properties of the textile product, and to be environmentally and economically acceptable. For the research, oil from the extract of the nim koji plant is used, which is prepared in the form of a solution with a defined concentration and ratio and used for the treatment of tissues. Samples are pretreated with plasma in the presence of oxygen or argon under defined conditions. Then the treatment is carried out by suction of the bath by spraying the material with a pneumatic pump. After the procedure, the analysis is carried out: the analysis of the macrostructure of the samples with a Dino-lite USB microscope, the micromorphological analysis of the cotton and modal fiber samples used with a microscope FE-SEM and the analysis of the antimicrobial activity of the microencapsulated essential oil of Nima with a qualitative microbiological test.
