Analysis study of nonwoven pineapple leaf fibre, nonwoven pineapple layered double weave and tricot knitting fabric as absorber material

Abstract

Sound pollution can be minimized by noise intensity using sound absorbing material. Nonwoven fabrics are the material most widely used for acoustic applications. This research investigated about absorption coefficient of nonwoven pineapple leaf fiber (PNW), and its layered combination with double weave (PDW) and tricot knitting fabric (PTK). The variation of fabric will be tested for sound absorption coefficient using an impedance tube. Absorption coefficient test results showed there was an effect in absorption coefficient on nonwoven with layered.

Revolutionizing Sustainable Nonwoven Fabrics: The Potential Use of Agricultural Waste and Natural Fibres for Nonwoven Fabric

“…In the study by Hanifah and Giarto (2019), a nonwoven fabric was produced from pineapple fibre (90%) and low-melt polyester fibre (10%) using the thermal bonding method under high temperature and pressure [107]. The results showed that the greater area density of fabric leads to higher thickness, density, strength, stretch, and filtering efficiency and lower water permeability, porosity, and pore size than other nonwoven fabrics.…”

“…In contrast to woven filters, nonwoven filters offer several advantages, including greater permeability, overall improved filtration efficiency, enhanced temperature resis-tance, and reduced pressure drops at equivalent efficiencies [194]. A study by Hanifah and Giarto (2019) used pineapple nonwoven fibres for producing air filters [107]. The results showed the nonwovens were particularly useful if the desired characteristics included thickness, density, tensile strength, elongation, and filtering efficiency of the nonwoven fabric and were less reliant on air permeability, porosity, and pore size.…”
