Processing Technique and Sound Absorption Property of Three-Dimensional Recycled Polypropylene Nonwoven Composites

Abstract:

Noise pollution has become a kind of serious environmental pollution problems. It not only makes people feel fatigue but also affects their concentration and work efficiency. People’s health and work efficiency could be promoted by improving and reducing the noise pollution problem. In this research, the recycled polyester (PET) fibers, polypropylene (PP) fiber and flame-retardant-hollow-crimp 7D PET fiber with a ratio of 2:1:7, 2:2:6, 2:3:5, 2:4:4, and 2:5:3 were fabricated and then needle-punched, creating the PET/PP/PET fabric. Next, a layer of recycled PP selvage and a layer of fabric were laminated in turn on the base fabric before needle-punching with a certain punching-depth, which was repeated until the 10-layer PET/PP/PET nonwoven composite was completed. Finally, the resulting PET/PP/PET nonwoven composite was measured with its physical properties and sound absorption ability.
