熱處理溫度對回收聚乙烯/聚酯吸音不織布之特性評估

隨著科技的進步，噪音污染愈來愈嚴重，而噪音問題一直以來就被人們所煩惱，為了解決噪音帶來的問題，消弱噪音是一種可行的方法，此外，由於石化產業蓬勃發展，塑膠製品愈來愈普遍，大量的塑膠垃圾隨之而生，這些塑膠垃圾會造成嚴重的污染，因此如何回收再利用變得更加重要所以本研究利用捲曲PET纖維與回收PE透過非織物製程製備出不織布並探討熱處理溫度對吸音及機械性質的影響，由結果發現，熱處理溫度對吸音係數沒有明顯的影響，在機械性質方面隨著熱處理溫度上升拉伸強力會有所上升而拉伸伸率則會下降。

As technology advances, more and more serious noise pollution, and noise has been trouble was that people, in order to solve the noise problems caused by weakening the noise is a feasible method. In addition, since the petrochemical industry is flourishing, plastic products increasingly common, a lot of plastic garbage along with the students, this plastic garbage can cause serious pollution, so how recycling has become more important. Therefore, this study crimped PET fibers and non-woven recycled PE through the process to prepare a non-woven, and to investigate the effect of heat treatment temperature on the acoustic and mechanical properties. From the results it found that the heat treatment temperature had no significant effect on the sound absorption coefficient. In terms of mechanical properties, as the heat treatment temperature rises, the tensile strength will be increased, while the tensile elongation is lowered.
