Abstract

Procjena antimikrobne aktivnosti tekstilnih materijala se provodi standardiziranim metodama koje donose različite organizacije za standardizaciju jedna od kojih je i ISO – Internacionalna organizacija za standardizaciju. Ciljevi ovog istraživanja su bili uvođenje i optimizacija ISO 20743:2013 i ISO 20645:2004 standarda za određivanje antibakterijske aktivnosti tekstilnih materijala u Laboratorij za bakteriologiju na Zavodu za mikrobiologiju Prirodoslovno-matematičkog fakulteta te određivanje... More antibakterijske aktivnosti materijala načinjenih na Tekstilno-tehnološkom fakultetu u sklopu projekta „Udobnost i antimikrobna svojstva tekstila i odjeće“ Hrvatske zaklade za znanost. Istraženi materijali su pamuk, sirova i obojena viskoza, tencel, mikromodal, modal, materijal X, materijal sa srebrom Aquacel Ag i antibakterijski uložak za cipele. Aquacel Ag, materijal X i uložak su pokazali antibakterijska svojstva na vrstama Staphylococcus aureus i Escherichia coli u sve tri korištene metode, a modal i mikromodal u dvije metode. Obojena i sirova viskoza su imale antibakterijska svojstva u jednoj od metoda za svaku bakteriju, a pamuk samo na vrsti E. coli u jednoj metodi. Tencel nije pokazao značajnija antibakterijska svojstva. Da bi se dobio točan rezultat, potrebno je paralelno koristiti nekoliko metoda i ispitati bar dvije vrste bakterija, jer se na temelju samo jedne vrste i jedne metode može pogrešno zaključiti o antibakterijskim svojstvima materijala.

Abstract (english)

An assessment of the antimicrobial activity of textile materials is carried out by standardized methods that are provided by different organizations, such as ISO - International Organization for Standardization. The aim of this study was to introduce and optimize ISO 20743: 2013 and ISO 20645:2004 standards for the determination of antibacterial activity of textile materials in the Bacteriological Laboratory at the Department of Microbiology of the Faculty of Science and to determine the... More antibacterial activity of materials made at the Faculty of Textile Technology as part of the project "Textiles and footwear comfort and antimicrobial properties". The investigated materials were cotton, crude and dyed viscose, tencel, micromodal, modal, material X, silver-containing material Aquacel Ag and antibacterial insoles for shoes. Aquacel Ag, material X and antibacterial insoles showed antibacterial properties against Staphylococcus aureus and Escherichia coli in all three methods, and modal and micromodal in the two applied methods. Dyed and crude viscose had antibacterial properties in one of the methods for each bacterium, and cotton only against E. coli in one method. Tencel showed no significant antibacterial properties. In order to obtain precise and relevant result, it is necessary to use several methods and at least two bacteria species, because only one species and one method can misconstrue the antibacterial properties of a material.
