Paper Title:
Characteristics of PP/PET Bicomponent Melt Blown Nonwovens as Sound Absorbing Material
  Abstract

Melt blowing(MB) is a process for producing fibrous webs or articles directly from polymers or resins using high-velocity air or another appropriate force to attenuate the filaments. This process is one of the newer and least developed nonwoven processes. This process is unique because it is used almost exclusively to produce microfibers rather than fibers the size of normal textile fibers. MB microfibers generally have diameters in the range of 2 to 4 ㎛, although they may be as small as 0.1 ㎛ and as large as 10 to 15 ㎛. The material acoustic property for noise absorption is principally based on the efficiency of material structures for damping sound wave reflections. In this paper, the sound absorbing material was designed with three layer composite sturcture. Sound absorbing material with fine meltblown(0.5~3 ㎛, 80%) and high modulus hollow fiber(30 ㎛, 20%) as a surface layer and bulky non-woven(15~30 ㎛) as middle layer, meltblown(3~10 ㎛) as bottom layer were manufactured. Their noise absorption were measured using the acoustic duct instrurment. The effect of the sound absorbing on the properties of PP/PET bico MB webs was investigated including the fiber diameter, weight, thickness and air permeability.
