ENVIRONMENTAL FRIENDLY ACOUSTIC NON WOVEN MATERIALS FROM SANSIVERIA AND ARECA HUSK FIBRES FOR HYGIENE LIVING

Abstract

An environmental friendly non woven fabric was developed by needle punching technique using sansiveria and areca husk fibres at constant punch density (200). The influence of fibre content of sansiveria and areca husk fibres (100:0, 70:30, 50:50, 30:70 and 0:100) on tensile, thermal conductivity, air permeability and sound absorption properties of the needle punched non woven fabrics were investigated. It is found that the tensile strength of areca husk non woven fabric has shown higher tensile strength of 8.42 N and 32.20 N respectively in machine and transverse directions. The sansiveria non woven fabric has given higher thermal conductivity and air permeabiliy. Highest sound absorption coefficient of 0.08 is obtained at higher frequencies. The non woven fabric developed in this work can be used as a sound insulation material for health care applications.
