METHOD AND APPARATUS FOR MANUFACTURING NOISE-ABSORBENT FABRIC, AND THE FABRIC

摘要

Disclosed is an apparatus for manufacturing a noise-absorbent fabric, which includes a hard layer making unit for laminating a fiber material sheet formed from raw fibers of a hard layer and then punching the fiber material sheet by needles to make a hard layer; a soft layer making unit for laminating a fiber material sheet formed from raw fibers of a soft layer on the hard layer and then punching the fiber material sheet by needles to make a soft layer; and a heating unit for heating the laminated hard and soft layers to be united with each other. Also, a method for manufacturing a noise-absorbent fabric using the above apparatus is also disclosed.
