20.500.12556/DKUM-20829 EKSTRAKT RDEČEGA BORA IN UV PROPUSTNOST MATERIALOV EXTRACT OF PINE WOOD AND UV PERMEABILITY ON MATERIALS Namen diplomske naloge je bil določiti vpliv dodatka ekstrakta rdečega bora na UV prepustnost barvane bombažne tkanine in ugotoviti možnost sočasne izvedbe postopka barvanja in UV zaščitne obdelave. Barvali smo z reaktivnimi barvili po izčrpalnem postopku in pri tem uporabili različne koncentracije barvila ter različne količine UV absorberja rdečega bora. Vzorcem smo nato izmerili UV prepustnost in izračunali UZF, ter hkrati opazovali vpliv dodatka rdečega bora na barvne vrednosti. Preverili smo tudi obstojnost apreture na miljenje in pranje. Ugotovili smo, da ekstrakt rdečega bora poveča zaščito tekstilnega materiala pred UV sevanjem, vendar pa se ta po večkratnem postopku pranja pomembno zniža, a kljub temu še vedno zagotavlja dobro zaščito. The purpose of presented diploma was to study the impact of applied extract of red pine on UV permeability of dyed cotton fabric, and to evaluate the possibility of combining two procedures, i.e. dyeing and UV finishing, in one. In the exhaustion dyeing procedure, we used different concentrations of reactive dyes and added different amounts of UV absorber extracted from red pine. All samples were spectrophotometrically evaluated as well as the UV permeability was measured, from which UPF factor was calculated. We have also observed resistance of such UV treatment to washing. It was found that extract of red pine had a significant impact on increasing protection against ultraviolet radiation. On the other hand, several washing procedures substantially decreased fabrics' UV protection.
