Abstract

The invention relates to a fibrous material for sound insulation in, for example, vehicles. The fibrous material comprises a first layer (2) of a continuous fibrous material, which has a portion of at least 50 % of short fibres having a length below 10 mm, a second layer (3) for free fibres or a fibrous web with a portion of at least 50 % of long libres having a length above 20 mm, and a binder in the form of a polymer which is added as latex and bonding the fibres in the two layers and which has thermoplastic properties after manufacturing the fibrous material. The invention further relates to a method for manufacturing the fibrous material, and using the fibrous material in a sound-insulating material.
