Scouring pad

Abstract

Provided is a scouring pad which includes a mesh net including a plurality of biodegradable filaments and a plurality of biodegradable monofilaments overlapping the filaments A plurality of protrusions are formed in a region in which the filaments overlap the monofilaments.

What is claimed is: 
     
         1 . A scouring pad, comprising:
 a mesh net including a plurality of biodegradable filaments; and   a plurality of biodegradable monofilaments overlapping the filaments, wherein a plurality of protrusions are formed in a region in which the filaments overlap the monofilaments.   
     
     
         2 . The scouring pad of  claim 1 , wherein the filaments form a lattice-like backbone structure and a network structure in the backbone structure. 
     
     
         3 . The scouring pad of  claim 2 , wherein the monofilaments form a twisted structure with the lattice-like backbone structure of the filaments. 
     
     
         4 . The scouring pad of  claim 3 , wherein the protrusions are formed at crossing points in a lattice shape of the backbone structure. 
     
     
         5 . The scouring pad of  claim 1 , wherein the protrusions are formed by the filaments and the monofilaments. 
     
     
         6 . The scouring pad of  claim 1 , wherein the protrusions have a height of about 1 to about 3 mm. 
     
     
         7 . The scouring pad of  claim 1 , wherein the filament is a multifiber including a plurality of threads, and the monofilament is a monofiber including a single thread. 
     
     
         8 . The scouring pad of  claim 1 , wherein the monofilament has a mean diameter of about 20 to about 50 times that of the filament. 
     
     
         9 . The scouring pad of  claim 1 , wherein the filament and the monofilament are formed of a material containing polylactic acid. 
     
     
         10 . The scouring pad of  claim 1 , further comprising an edge sewing line disposed along an edge of the mesh net. 
     
     
         11 . The scouring pad of  claim 10 , wherein the edge sewing line is formed with the biodegradable filament. 
     
     
         12 . The scouring pad of  claim 10 , wherein the edge sewing line is formed with a material containing polylactic acid.
