Abstract:
Provided is a waterproof sound-permitting sheet, including: a porous substrate having a plurality of pores; and a porous nanoweb, which is stacked on the porous substrate, has a plurality of pores, and is formed by electrospinning a polymer material to which a black or a different color pigment is added, thereby improving waterproofing performance and sound penetration performance by forming on a porous substrate, such as non-woven fabric, the porous web having the black or the different color by using the electrospinning method, and can shorten a production process by eliminating a pigment coating step by means of adding the pigment to the polymer material when manufacturing the porous nanoweb according to the electrospinning method.
