PP/PET混合S型结构吸音棉的制备与吸音性能研究

Preparation of PP/PET Hybrid S-shaped Structure Sound-absorbing Fiber and the Research of Sound Absorption

通过在PP/PET纤维结晶过程控制纤维堆积方法,构筑成S型结构,制备出具有优异吸音功能的混合吸音棉。研究结果表明,S型结构比U型结构的混合堆积棉对中低频噪音具有更好的吸音效果。

By regulating the fiber accumulation method in the fiber crystallization process, S - shaped structure sound - absorbing blend fiber was prepared that was excellent in sound absorption. S - shaped structure blend fiber was better than U -shaped structure fiber in low and medium frequency sound absorption.
