Manufacturing Technique and Property Evaluations of Degradable Sound-Absorption Plates

Following the high quality of life that people pursue, the requirements to air and environment are stricter. People value the quality of sleeping and public safety, thus they pay more attention to prevent noises. Noise makes people weary and distracted, and may eventually result in accidents. Therefore, this study uses polylactide fiber (PLA) and low melting point polylactide fiber (LPLA) to make sound absorbent PLA/LPLA plates, after which the tensile strength, softness, and sound absorption of the plates are evaluated.
