A DESIGN OF ETHYLENE REMOVAL NON-WOVEN TEXTILE BY USING NATURAL ZEOLITE AND POTASSIUM PERMANGANATE ABSTRACT Ethylene has a significant role in plants development and maturing and isproduced as gas hormone by plants themselves. In 1 μL L-1 concentrations, it has beneficial effects for fresh vegetables and fruits (FFV) but when this gas is accumulated around the FFV it causes aging and deterioration. During the storage, transport and marketing it affects the quality and freshness of FFV. There are technologic solutions for eliminating the ethylene gas accumulating in storage atmosphere problem but these techniques are practical fo . . .r rutine usage and have high cost. Natural minerals have a very low cost, a great potential for practical use and are easily attainable to improve the storage conditions. Natural zeolites are one of the most promising materials that have desirable properties such as ion exchange, catalyzer, adsorption and molecular sieve. Due to the properties and the advantages, they attain a great place in many areas. Zeolites have large surface area so they are used as bed materials for potassium permanganate used for ethylene decomposition. Nowadays textile nonwoven surfaces have increasing attention in technical and industrial fields. They can be modified to meet any needs with their unlimited opportunities, in many fields where the performance and quality are required. In this study, textile nonwovens were modified by using natural zeolites and potassium permanganate whichis used as ethylene removal textile.This combination can be used as practical and disposable product. For evaluation and characterization of samples, particle size analysis, surface (BET) analysis, SEM, XRD, FT-IR, air permeability and water vapor permeability tests were conducted. Adsorption performance properties were tested via IR spectrum changes. Nonwoven textileprovided extendedsurface area and performance, and eliminated the toxic effects of potassium permanganate that causeshealth problems. A new kind of xx product was obtained by using natural zeolites, which are found in abundand amounts in Turkey.Rectorship of Izmir Katip Çelebi University granted this master of thesis (2013-TEZ-1-49 numbered Scientific Research Projects) Daha fazlası Daha az
