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).
