Sound-Absorbing Evaluation on Nylon 6/Low-Melting PET Nonwoven Fabric

Abstract:

In recent years, as quality life improves, people begin to focus on quiet environment. Long-term noise pollution makes trouble of dysphoria and concentrating for people, thus noise-reduction has become an urgent project. This study uses Nylon 6 fibers, blended with different contents of low-melting PET fibers (10 wt%, 20 wt%, 30 wt%, 40 wt% and 50 wt%), to fabricate Nylon6/ LPET nonwoven fabrics after needle-punching process. Afterwards, their maximum tensile strength, air permeability, sound absorption coefficient were all evaluated. When low-melting PET fibers contain 30 wt%, the nonwoven fabric has the better sound-absorbing property. Herein, the maximum tensile strength reaches 70.79 N and 31.01 N, respectively in CD and MD; the air permeability is about 116.5 [cm3/(cm2/s)]
