Abstract

The invention relates to a sound absorbing material, made from a microfilament non-woven fabric with a mass per unit surface area of 40 to 300 g/m2, whereby a non-woven fabric made from a melt-spun and drawn multi-component endless filament with a titre of 1.5 to 5 dtex is directly bonded to form a web and the multi-component endless filaments are optionally spread with and fixed to micro-endless filaments with a titre of 0.1 - 1.2 dtex, up to a degree of 80 % by means of a prefixing process.
