Effect of Fiber Fineness on Acoustic Absorption Property of Nylon 6/Low-Melting PET/Recycled PET Nonwoven

Abstract:

In recent years, as global technical progress grows, many mechanized machines are developed continuously. Mechanization has substituted for manpower in many factories for promotion of production efficiency, leading to mechanical noise happening more severely. If people are subjected to noise pollution for long term, they would happen dysphoria and absent mindedness, resulting in accident occurrence. Therefore, how to effectively reduce noise pollution becomes an urgent subject. Moreover, rapid population development and fast-growth economy raise consumption in every country, driving industry into high-production and high-consumption times and meanwhile generating much of wastes. In order to achieve sustainable development, these wastes should be recycled effectively. Therefore, 20 wt% recycled PET fibers were added in this study. This paper mainly used 3D and 15D Nylon fibers (70, 60, 50, 40, 30 wt%), low-melting PET fibers (10, 20, 30, 40, 50 wt%) and 20 wt% high-strength PET fibers, to fabricate Nylon 6/Low melting PET/ Recycled high-strength PET nonwoven via needle-punching process. After that, tensile strength, air permeability and sound absorption coefficient property of resulting nonwoven were tested and then evaluated respectively.
