Filament iplik teknolojisindeki gelişmelerle birlikte ürün tasarımındaki yenilik arayışları birleştirildiğinde, bu ipliklerin tekstil endüstrisinde değerlendirilmesi adına farklı alternatifler ortaya çıkmaktadır. Buradan hareketle filament ve multifilament iplik yapılarının denim sektöründe kullanılabilirliği araştırma konusu olmuştur. Bu çalışmada yedi farklı filament sayısındaki multifilament polyester iplikler kullanılarak denim kumaşlar tasarlanıp, üretilmiştir. Kumaşlarda kopma mukavemeti (atkı/çözgü), yırtılma mukavemeti (atkı/çözgü), esneklik, yumuşaklık, hava geçirgenliği, nem alma ve su geçirgenliği testleri gerçekleştirilmiştir. İpliği oluşturan filamentler incelerek daha mikro yapıya ulaştıkça yumuşaklığının arttığı, bu sırada ise hava geçirgenliklerinin azaldığı görülmüştür. Bununla birlikte iplik yapısındaki filamentler inceldikçe de, kumaşlarda kalıcı uzama açısından problemlerin yaşanabileceği öngörülmektedir.
Electro-Fenton (EF) is a system where electrooxidation and electrocoagulation come together. In the EF method, it is aimed at creating OH radicals in an electrochemical cell by catalyzing H2O2 with Fe2+ ions. In this study, optimization of process variables for the removal of reactive azo dye (reactive yellow 145) from aqueous solution by the electro-Fenton method was carried out using response surface methodology. The percentage of dye removal and energy consumption were selected as the response functions for the 5 variables determined as voltage, H2O2 concentration, pH, electrode spacing, and processing time. As a result of 32 experiments determined by the Design Expert 13 program, the effect of variables on response functions was examined separately and together. 10 V voltage to 99.4%, which is the highest removal; pH 2.5; 1 cm electrode range; 1 mL H2O2 addition; and 22.16 Wh/L energy consumption in a 70-min treatment time were reached. The optimum values of the variables proposed by the program to ensure the highest dye removal efficiency (approximately 93%) and the lowest energy consumption (approx. 3.4 Wh/L) are approximately 9.4 V voltage, pH 3.7, 2.5 cm electrode range, 1 mL H2O2 addition, and a 40-minute treatment time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
