    • PURPOSE: Environmentally friendly nonwoven fabric capable of recycling is provided to make recycle possible since it is made of components of polyester series, prevent the generation of volatile organic compounds since adhesives of latex series are not used, and to show excellent biodegradability in a waste treatment process. CONSTITUTION: Environmentally friendly nonwoven fabric capable of recycling comprises a sound absorption layer(30), an adhesive layer(2) formed on a top surface of a sound absorption layer, and a skin layer(10) which is formed on a top surface of an adhesive layer and has piles on an outer surface. A manufacturing method of environmentally friendly nonwoven fabric capable of recycling comprises a skin layer formation step forming piles(11) at a lower surface of the first nonwoven fabric which is needle punched after needle punching a laminated web formed by carding the first nonwoven fabric; an adhesive layer formation step forming an adhesive layer with the second nonwoven fabric; a bonding step of laminating an adhesive layer manufactured with an adhesive layer formation step on a top surface of a skin layer manufactured with a skin layer formation step and a subsequent needle punching; a melting step melting a top surface of a laminate formed through a bonding step; and a sound absorption layer forming step laminating a sound absorption layer on a top surface of a laminate.
