20.500.12556/DKUM-87078 Cotton woven fabrics as protective polymer materials against solar radiation in the range of 210–1200 nm The proposed paper describes the influence of woven fabric constructional parameters (type of weave, relative fabric density) and colouration (obtained by eco-friendly dyeing) on the solar transmittance of cotton woven fabrics in the range of 210-1200 nm. The cotton woven fabrics in their raw state were prepared according to Kienbaum's setting theory, at three levels of relative fabric density and three levels of the weave factor, and then exposed to the dyeing process with natural dyestuffs (beetroot, walnut leaves). After ultraviolet/visible/near-infrared (UV/VIS/IRA) solar transmittance and reflection in the range of 210-1200 nm were recorded, the influence of the fabric construction and colouration were analysed. The guidelines for fabric constructor were proposed. The results show that the walnut-coloured satin samples at the third level of relative fabric density provide the best solar protection in the whole solar spectrum. All the tested eco-friendly dyed fabrics offer good solar protection, while only raw satin fabric at the third level of relative fabric density can be classified as solar protective material with even better protection in IRA region than some coloured samples. fabric engineering solar protection woven fabric structure natural dyeing of polymer material testing tekstilno inženirstvo UV zaščita struktura tkanine naravno barvanje polimernega materiala testiranje true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/polymers Članek v reviji 2024-02-15 12:33:18 2024-02-15 12:41:48 2024-04-10 11:19:28 0000-00-00 00:00:00 2023 0 0 Str. 1-12 Št. 5, št. članka 1310 Letn. 15 Mar. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-01-23 2023-03-02 2023-03-06 677.027.625.52 144510979 10.3390/polym15051310 2073-4360 Dubrovski-2023-Cotton_Woven_Fabrics_as_Protect.pdf Dubrovski-2023-Cotton_Woven_Fabrics_as_Protect.pdf 1 DC0A81C039096CF2DB2BE73F8E29665A 75a57131e54c3d255bbcc6063486a038e518a682eab23a88adb9d54d2d47ac23 165cd637-cbf7-11ee-be42-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=176190 https://doi.org/10.3390/polym15051310 0 21e430da-cbf7-11ee-be42-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=176191 Fakulteta za strojništvo 0 0 0
