Thermal and Sound Insulation Performances of Building Panels Produced by Recycling Waste Fibres of Yarn Factories

Abstract

Waste recovery is very important issue due to having vital effects on sustainability of economy and environment health. Recycling of materials such as textiles, plastics, glasses, papers and metals instead of storing, burying or burning results a reduction in raw material demands of industry. This means also that a reduction in amount of money, time and energy spent on to obtain raw materials. From this point of view, the main purpose of this study was determined as the production of textile surfaces with high waste fiber content by recycling textile fiber wastes in sizes that cannot be used in the textile manufacturing industry again. In this sense, various composite plates that can be used for sound and heat insulation on the exterior and interior surfaces of the buildings were produced by using unconventional methods from the waste fibers varying between 0.1-25 mm lengths. Another aim of the study was to produce widely used panels at low costs in order to compete with commercial products. The effect of changed parameters such as density, fiber type, waste fiber ratio and aluminum foil layer addition were investigated. As a result of the tests, it was observed that the thermal conductivity coefficient values of the all produced composite panels varied between 0.033-0.038 W/mK, and the sound transmission loss values between 24.2-32.6 dB. For further studies, the produced samples also showed that they are convenient to innovation in the lights of results.
