Extraction and Characterization of Natural Fibers for Acoustic Nonwoven Fabric Development

The utilization of natural fibers in textile applications increases day by day because of the availability in abundance, bio-degradable, economical and eco-friendly. Due to industrial revolutions and the transformation of world towards a wide range of research and developments, human community facing a lot of noise pollution. Hence the academicians and industrial sector peoples finds their time to exploring the process to reduce noises. A need for acoustic material in reducing the noise that too environment friendly is an obliged one for our society. In this research the objective is to identify natural fibers and develop an ecofriendly, light weight nonwoven material with optimized parameter for acoustic application. Initial process begins with the identification and extraction natural fibers from Areca nut husks. Then examination of the extracted natural fibers for their chemical, physical, and mechanical properties. Optimization of nonwoven fabric formation was done with three variables using Response surface methodology—Box-Benham method with single level. The variables such as blending ratio, bonding technique and needling density that yielded the best results in optimization process for selected fibre extracted was selected. Then the fabrics functional properties were analysed. Based on the outcomes of extracted fibre to check for its acoustic application there is a huge potential for these fibers to be used for acoustic application as a sustainable material. This investigation is being carried out with the hope of increasing the utilization of agro-waste fibers in the textile industry by means of nonwoven technology for acoustic applications, which is made possible by recent technological developments.
