Abstract:
Environmental consciousness all throughout the world has triggered a need for developing sustainable materials from renewable resources. Thus, the main goal of the present study is to assess the physical and mechanical properties of prepared needle punched nonwoven mat from tailor discards. Hence, thermal conductivity and sound insulation properties of nonwovens consisting textile discards were blended with kapok fiber in different ratios of 100 and 50-50% were explored. Absorbtion coefficient ranging from 0.1Hz to 0.23Hz were measured, thermal conductivity values from 2.01 to 3.77 w/mk were obtained and an abrasion mass loss close to 18.9% was found. Measurement results showed that the manufacturing processes mainly affect the sound and thermal properties of the nonwoven mats.
