Published by Elsevier Ltd.Öğe Investigation of pumice stone powder coating of multilayer surfaces in relation to acoustic and thermal insulation(SAGE Publications Ltd, 2015) Canbolat, Şeyda; Kut, Dilek; Dayıoğlu, HabipIn this study, production of multilayer surfaces for acoustic and thermal insulation was investigated. After the optimum textile materials had been chosen to provide acoustic and thermal insulation, surfaces were created using different relative methods in this field. Sublayer nonwoven produced from slotted polyester fiber was combined with two different top layers of fabrics, one of which was the top layer of fabric woven from plain weave obtained from texture yarns, which, in turn, was produced from hollow polypropylene, and the other was plain weave obtained from texture weft yarn, which was produced from conventional polypropylene fibers separately. Subsequently, these two different surfaces were combined with polyurethane-based material. Pumice stone powder in three different concentrations and two different sizes was added to enhance acoustic and thermal insulation, after which the sublayer had been coated with an adhesive material to produce multilayer adhesive force and adherence to the wall. Consequently, air permeability, sound absorption, and thermal conductivity coefficients of multilayer surfaces were researched with regard to the type of top layer of fabrics, concentration, and particle size of pumice stone powder. The results demonstrate that the properties of multilayer surfaces concerning acoustic and thermal insulation increase with the increasing concentration of pumice stone powder and with the decreasing sizes of pumice stone particles. In addition, air permeability of multilayer surfaces was ensued to decrease with the increasing concentration as well as particle size of pumice stone powder. © The Author(s) 2013.Öğe Investigation of the bee-repellent properties of cotton fabrics treated with microencapsulated essential oils(SAGE Publications Ltd, 2019) Eyüpoğlu, Şeyda; Kut, Dilek; Girişgin, Ahmet Ongun; Eyüpoğlu, Can; Özüiçli, Mehmet; Dayıoğlu, Habip; Aydın, LeventIn this study, to produce single-use bee-repellent fabrics, a variety of essential oils were encapsulated with gum arabic wall material at a 1:5 ratio of wall to the core substance. The following core substances were used: lavender oil, laurel oil, fennel oil, N, N-diethyl-3-methylbenzamide (DEET), lavender + laurel oil, lavender + fennel oil, laurel + fennel oil, lavender + fennel + laurel oil, lavender oil + DEET, fennel oil + DEET and laurel oil + DEET. Lavender, fennel and laurel oils were analyzed by high-performance liquid chromatography. In this context, 11 different microcapsules were produced. After the microencapsulation process, the microcapsules were analyzed with a light microscope and by Fourier transform infrared spectroscopy. Furthermore, an image processing application was developed and implemented to determine the particle size distribution of the microcapsules. After the analysis of the microcapsules, cotton fabric samples were treated with the microcapsules. In order to analyze the microcapsules on the fabric samples, scanning electron microscopy (SEM) was used. To analyze the bee-repellent abilities of the fabric samples, 12 different measurement cabinets made of pine tree and glass were produced. According to the results, lavender and fennel oils can be used as bee-repellent alternatives to DEET in beekeeping. © The Author(s) 2018.Öğe Investigation of the effect of the dyeing method on the dyeing properties of silk fabric dyed with natural dye(İstanbul Aydın Üniversitesi, 2014) Canbolat, Şeyda; Merdan, Nigar; Kut, DilekIn this study, silk fabric was dyed with the natural dye extracted from blueberry (Vaccinium corymbosum L.) via ultrasonic, microwave and conventional methods.
