Abstract
Provided is a waterproof sound-permitting sheet, including: a porous nanoweb that has a plurality of pores and that is formed by electrospinning a polymer material to which a black or a different color pigment is added, thereby shortening a manufacturing process and improving waterproofing performance and sound-permitting performance.
Claims5
A waterproof sound-permitting sheet comprising:
- a porous nanoweb layer formed of accumulation of ultra-fine fiber strands and having a plurality of first pores, wherein the ultra-fine fiber strands have an average diameter in a range of 0.3-1.5 μm, the first pores have an average size in a range of 1.5 to μm, and the ultra-fine fiber strands are formed of a polymer material and a color pigment;
- and
- a double-sided adhesive tape stacked along an edge of the porous nanoweb layer, wherein the double-sided adhesive tape comprises:
- a substrate formed in a nanoweb form and having a plurality of second pores;
- a first adhesive layer formed on a first surface of the substrate;
- and a second adhesive layer formed on a second surface of the substrate, the second surface being opposite to the first surface.
