20.500.12556/RUL-135188 Use of extended cover factor theory in UV protection of woven fabric The paper presents an extension of existed cover factor theory more suitable for the evaluation of light penetration through a net woven fabrics structure. It also introduces a new simplified model of predicting the ultraviolet (UV) protective properties of woven fabrics assuming that the coefficient of reflection (K$_R$), transmission (K$_T$), and absorption (K$_A$) of constitutive yarns are known. Since usually they are not, the procedure of preparation of simulation of proper woven fabric samples without interlacing and with known constructional parameters is also presented. The procedure finishes with a fast and cheap detection of missed coefficient for any type of yarns. There are differences between theoretical and measured results, which are not particularly significant in regard to the purpose and demands of investigation. cover factor simplified model of UV penetration woven fabrics simulation coefficient K$_R$ K$_T$ and K$_A$ determination faktor kritja poenostavljeni model za napovedovanje UV prepustnosti simulacija tkanin koeficient K$_R$ določanje K$_T$ in K$_A$ true false true Angleški jezik Slovenski jezik Članek v reviji 2022-02-28 11:04:57 2022-02-28 11:04:59 2022-09-14 04:12:03 0000-00-00 00:00:00 2021 0 0 13 str. iss. 8, art. 1188 Vol. 13 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677 2073-4360 10.3390/polym13081188 59192323 RAZ_Kostajnsek_Klara_2021.pdf RAZ_Kostajnsek_Klara_2021.pdf 1 5989BDFC945E26F42E772E8FC630AEBF e018e77d34aeaf7864903a1ec7daf585cd4c570271d91be240adaa067f4fc59e ff476722-987d-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154084 https://www.mdpi.com/2073-4360/13/8/1188 1 9f7f0a34-987d-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154083 Naravoslovnotehniška fakulteta 0 0 0
