20.500.12556/RUL-134882 Optical assessment of porosity parameters in transparent woven fabrics This paper deals with the possibility of a fast and accurate assessment of the number, size, and distribution of pores in transparent woven fabrics based on light penetration. The procedure of analyzing the pore structure in the fabrics based on a digital image is presented in detail. Fabric pores are treated as image particles and analyzed with the Java-based image processing software ImageJ. The obtained data relate to the constructional parameters of the fabric that allow for further analysis, provide the possibility to compare structurally similar or different samples as well as double check the results generated by optical or other means. This paper describes work on plain and similar to plain weaves. The conducted analysis revealed several expected and some unexpected results. Among the former, we can list the range of pore sizes in the examined woven fabrics, the distribution of pores in regard to their similarity, and the effect of dents. Examples of the latter are the magnitude of the cumulative percentage of pores in regard to the weave and the degree to which they participate in the inter-yarn and inter-fiber pores. pore size pore size distribution porosity parameters weaves woven fabrics cover factor image analysis velikost por porazdelitev velikosti por parametri poroznosti vezave tkanine faktor kritja slikovna analiza true false true Angleški jezik Slovenski jezik Članek v reviji 2022-02-10 09:44:10 2022-02-10 09:44:12 2022-09-14 04:10:28 0000-00-00 00:00:00 2021 0 0 16 str. iss. 3, art. 408 Vol. 13 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677 2073-4360 10.3390/polym13030408 49120515 RAZ_Kostajnsek_Klara_2021.pdf RAZ_Kostajnsek_Klara_2021.pdf 1 E32B66D9E86FE25E77897E842F183AD5 7c5a41d6587f0e683420f9eca81db779ac5b095b5b8d5372adea88db375ab43c a628f1a0-8a4d-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153601 https://www.mdpi.com/2073-4360/13/3/408 1 63bb9947-8a4d-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153600 Naravoslovnotehniška fakulteta 0 0 0
