20.500.12556/RUL-128691 Influence of optical brightening agent concentration on properties of cotton fabric coated with photochromic microcapsules using a pad-dry-cure process The weak photostability of photochromic dyes applied to textile substrates is one of the disadvantages of the broader use of photochromic dyes in the textile industry. Therefore, the influence of optical brightener concentration on both the photocoloration and photostability of cotton fabric coated with photochromic microcapsules using a pad-dry-cure process, as well as the physical-mechanical properties and colorfastness properties, were studied in this research. Coated samples were subjected to different tests according to valid EN ISO standards; namely mass per unit area, fabric stiffness, breaking force and elongation, air permeability, and different colorfastness properties (rubbing, domestic and commercial laundering, and light). Results showed that the coated fabric had higher mass per unit area, stiffness, breaking force and elongation and lower air permeability compared to uncoated fabric, irrespective of the padding bath composition. Coated fabric has better colorfastness to wet than dry rubbing. The colorfastness to washing decreases with the increased number of washing cycles. The use of optical brightener decreases the photocoloration of coated fabric and increases the photostability of coated fabric after the exposure of samples to a Xenotest apparatus for longer than 12 h. photochromic microcapsules photocoloration cotton optical brightening agent pad-dry-cure process fotokromne mikrokapsule fotobarvanje bombaž optično belilo impregrnirni postopek true false true Angleški jezik Slovenski jezik Članek v reviji 2021-07-23 10:38:59 2021-07-23 10:39:00 2022-09-07 04:16:39 0000-00-00 00:00:00 2019 0 0 11 str. iss. 12, art. 1919 Vol. 11 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677 2073-4360 10.3390/polym11121919 3681392 RAZ_Kert_Mateja_2019.pdf RAZ_Kert_Mateja_2019.pdf 1 85D622C64D542ABF6D1A313966D45154 3c048b33fcd4028bc70621ea08994f3e5c864ad403dd28df3d11eabf30e543f3 f3427181-eba7-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145531 https://www.mdpi.com/2073-4360/11/12/1919 1 4436d894-eb91-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145512 Naravoslovnotehniška fakulteta 0 0 0
