    • PURPOSE: A method for fabricating a soundproofing material is provided to recycle polyurethane foam and to prevent and to prevent static electricity generation. CONSTITUTION: A method for fabricating a soundproofing material comprises: a step of finely pulverizing a waste sheet; a step of mixing a polyester-based fiber, polyester-based fiber of low melting point, polypropylene fiber, thermoplastic fiber, and hemp in a polyurethane foam-crushed material; a step of carding the mixture; a step of needle-punching; a step of thermoforming and cooling; and a step of forming the mixture in a felt and cutting. The polyurethane foam is waste sheet foam or thermosetting polyurethane foam.
