INVESTIGATION ON SOUND ABSORPTION PROPERTIES OF THE TEXTILE FABRICS INCLUDED RECYCLED FIBERS
Project no. 710 · Status: Kapanmış · 2015
Summary
Noise has become an increasing public health problem and serious environment pollution in our daily life. Generally, it is impossible to treat most of the noise problems at source and the reduction of noise emission is usually accomplished by noise isolation methods. Recently, nonwovens, as one of the most common textile products, have become important sound absorption materials. These materials are used as sound absorbers, sound diffusers, noise barriers or sound reflectors. For sustainable development of the textile industry, solutions for both decreasing waste and reducing noise have been searched for years. Since recycled materials exhibit good sound absorbing properties, these materials are becoming an interesting alternative to conventional materials for practical applications. In this study, the measurements methods of acoustic characteristics of textile materials were explained and the sound absorption properties of nonwoven fabrics produced from both pure and recycled polyester and polypropylene fibers are compared.
