Heritage ethnographic objects - antimicrobial effects of chitosan treatment

[EN] Chitosan is a natural polymer, which presents, according to studies made up to present, low toxicity and good biocompatibility. Recent studies are focused not only on its antimicrobial effects on textiles, because this polysaccharide leads to improvements such as: shrink resistance, dye uptake etc. Two Romanian traditional shirts were non-invasively tested by applying Chitosan and by investigating the SEM images, before and after applying the chitosan. The paper underlines the surface modifications of tested textiles using chitosan. The odd agents on the fibres surfaces were removed and the limitation of the number of microorganisms was observed[Otros] Chitosanul este un polimer natural care, conform studiilor realizate pân¿ în prezent, prezint¿ o toxicitate sc¿zut¿ ¿i o bun¿ biocompatibilitate. Studii recente, care se concentreaz¿ nu doar pe efectele sale antimicrobiene asupra materialelor textile, au eviden¿iat c¿ aceast¿ polizaharid¿ conduce la îmbun¿t¿¿iri din punctul de vedere al rezisten¿ei la contrac¿ie, precum rezisten¿a la contrac¿ie, absorb¿ia coloran¿ilor etc. Dou¿ c¿m¿¿i tradi¿ionale române¿ti (ii) au fost testate neinvaziv prin aplicarea chitosanului ¿i prin investigarea imaginilor SEM, înainte ¿i dup¿ tratamentul cu chitosan. Lucrarea eviden¿iaz¿ modific¿rile de pe suprafa¿a ¿es¿turilor testate folosind chitosan. Dup¿ îndep¿rtarea agen¿ilor de pe suprafa¿a fibrelor, s-a remarcat reducerea num¿rului de microorganismeThe research was possible by equal scientific involvement of all authors and acknowledges the support of the Grant PN-III-P1-1.2-PCCDI-2017-0686Indrie, L.; Bonet-Aracil, M.; Ilies, DC.; Albu, AV.; Ilies, G.; Herman, GV.; Baias, S....
