The global demand for sustainable and functional fibers and textile materials is increasing with the pressure to limit the synthetic petroleum-based counterparts. In this study, we use ultrasonication for the preparation of eco-friendly cellulose fabrics bearing silver or gold nanoparticles (NPs). The mechanochemistry of cellulose is based on the breakage of glycosidic bonds and the formation of mechanoradicals. These mechanoradicals can reduce Au3+ and Ag+ ions in solution, and the reduced metals can be stabilized by the cellulose chains as nanoparticles. Here, we formed the mechanoradicals in the fabrics by sonication (on the order of 1018 per gram), which is confirmed by ESR. The sizes and the metallic nature of NPs and the structural and morphological changes in the fabrics upon ultrasonication were studied by SEM, XPS, FTIR-ATR, XRD, and TEM. The displayed preparation method is shown to yield antibacterial AgNP-fabric and catalytically active AuNP-fabric composites, with up to a 14% yield of metal ion reduction. Since the method involves only the sonication of the fabric in aqueous solutions, and uses no hazardous reducing and stabilizing agents, it provides quick and environment-friendly access to fabric nanocomposites, which have applications in medical textiles, catalysis, and materials for energy.

SUPERCRITICAL CO2 FOAMING OF PLLA WITH LIQUID CO2-PHILIC CELL NUCLEATORS Çulhacıoğlu, Yağmur; Hasırcı, Nesrin; Dilek Hacıhabiboğlu, Çerağ (null; 2018-09-01) There is an increasing trend towards replacing synthetic polymers with their natural counterparts and applying environmentally friendly processing techniques [1]. For both industrial and biomedical applications, natural originated biodegradable polymers are intensely studied due to their environmentally benign and biocompatible nature. Supercritical carbon dioxide (scCO2)processing of polymers is a green approach since it reduces or eliminates the use of organic solvents and thus emissions of volatile organ...
SILVER NANOWIRE BASED MULTIFUNCTIONAL FIBERS AND FABRICS Doğanay, Doğa; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2022-11-23) The demand for functional textiles has been increasing for the last two decades. In particular, advancements in the internet of things, artificial intelligence and data science have forced scientists and engineers to develop better functional and/or electronic textiles that meet consumer demands. However, due to some deficiencies, functional textiles could not reach their true potential. Some of these deficiencies can be addressed with practice-based approaches. On the other hand, there are also some univer...
Sustainable textile production: a case study from a woven fabric manufacturing mill in Turkey Alkaya, Emrah; Demirer, Göksel Niyazi (Elsevier BV, 2014-02-15) The aim of this research was to investigate the applicability of different sustainable production measures and demonstrate environmental and economical benefits in a woven fabric manufacturing mill in Bursa, Turkey. As a result of an Environmental Performance Evaluation (EPE) evaluation, five sustainable production applications were proposed and implemented to decrease water consumption, wastewater generation, energy consumption, greenhouse gas emissions and salt (NaCl) consumption in the company. As a resu...
Nanostructured poly(lactic acid)/soy protein/HPMC films by electrospinning for potential applications in food industry Aydogdu, Ayca; Yıldız, Eda; Ayhan, Zehra; Aydoğdu, Yıldırım; Şümnü, Servet Gülüm; Şahin, Serpil (2019-03-01) As an alternative to oil based materials, there is a demand for easily degradable packaging materials. With this regard, the objective of this study is to produce bilayer nanofiber sheets composed of Poly (lactic acid) (PLA) and soy protein, hydroxypropyl methylcellulose (HPMC) and combination of them by using electrospinning. In addition, it was aimed to analyze morphological, optical, thermal properties of films and investigate permeability characteristics. Homogenous nanofibers were successfully collecte...
Catalytic ozonation of synthetic wastewaters containing three different dyes in a fluidized bed reactor Balcı, Ayşe İrem; Özbelge, Ayşe Tülay; Department of Chemical Engineering (2011) Environmental regulations have imposed limitations on a wide variety of organic and inorganic pollutants in industrial textile wastewaters. There are several degradation methods used in literature studies. Among these methods ozonation is one of the most considered way to degrade refractory chemicals in textile wastewaters. In recent years, catalytic ozonation as being one of the advanced oxidation processes (AOPs), is applied to reduce the ozone consumption and to increase the Chemical Oxygen Demand (COD) ...
