Abstract:

In order to resolve the peoblems on the waste textile fibers recycling and the noise pollution in daily life, composite with good sound insulation property were prepared from waste polyester fabric and chlorinated polyethylene (CPE) by a hot-processing method. Firstly, it was found that the sound insulation property of the waste polyester fabric/CPE composites was the best according to the sound insulation curves of waste polyester fabrics, CPE plate and waste polyester fabric/CPE composites. Secondly, the sound insulation properties of the composites which were prepared by changing the waste polyester fabric layer number and density and pressure were tested. It was showed that the sound insulation property were improved by increasing the waste polyester fabric layer number and density and pressure. Then, the sound insulation quantity of the composite was calculated according to a theoretical model. By comparisons of theoretically calculated and actually measured value of the sound insulation quantity, it is showed that the the theoretically calculated values have good match with the actually measured values.

Key words: waste polyester fabric, sound insulation property, composite, sound insulation quantity, chlorinated polyethylene
