Abstract:Namen diplomskega delu z naslovom »Postopki plemenitenja za zmanjšanje UV prepustnosti materialov« je bilo proučevanje UV prepustnosti različnih tkanin, obdelanih s potencialnim UV absorberjem, ekstraktom rdečega bora, po različnih tehnoloških postopkih. Analizirala sem pet tkanin, ki so izdelane iz bombaža, poliamida, mešanice bombaža in poliestra v različnih konstrukcijah, gostoti, teži in zračni prepustnosti, saj vse tekstilije niso primeren filter za UV žarke. Te tkanine sem naknadno plemenitila z nanosom UV absorberja po impregnacijskem postopku na foulardu in primerjalno po izčrpalnem postopku. Vsem vzorcem sem spektrofotometrično izmerila UV prepustnost in izračunala UPF faktor. Ugotovila sem, da ima rdeči bor kot uporabljen UV absorber pomemben vpliv na zaščito pred ultravijoličnim sevanjem, njegova učinkovitost pa je v veliki meri odvisna od materiala, tehnološkega postopka in strukture tekstilije.
Keywords:UV absorber, UV prepustnost, rdeči bor, UPF, UVA, UVB.

Title:FINISHING PROCEDURES FOR REDUCTION OF MATERIALS UV PERMEABILITY
Abstract:The purpose of presented diploma, entitled »Finishing procedures for reduction of materials’ UV permeability« was to study the UV permeability of various fabrics treated with the potential UV absorbers, an extract of red pine, according to different processes. I was analyzed five fabrics, made from cotton, polyamide, polyester and cotton blends, with different structure, density, weight and air permeability, because all textiles are not appropriate filter for UV rays. These fabrics were subsequently finished with UV absorber according to padding procedure on foulard and, comparatively, according to exhaustion procedure. All samples were spectrophotometrically evaluated by measuring UV permeability, from which the UPF factor was calculated. I was found that the red pine, used as UV absorber, has a significant impact on the protection against ultraviolet radiation. Its effectiveness is exceedingly dependent on the material, technological procedure and the structure of textiles.
Keywords:UV absorbers, UV permeability, Pine Wood, UPF, UVA, UVB.
