NET-LIKE ARTICLE AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a net-like article which can effectively separate fluids such as gases and liquids from solids such as soil.

SOLUTION: This net-like article produced by integrally laminating the first fiber layer prepared by irregularly meandering and accumulating continuous filaments to the second fiber layer prepared by irregularly meandering and accumulating continuous filaments is characterized in that the continuous filaments constituting the first fiber layer are formed in larger diameters than the continuous filaments constituting the second fiber layer; the penetrated holes of the first fiber layer are larger than the penetrated holes of the second fiber layer; and the penetrated holes of the first fiber layer and the second fiber layer are continued in the thickness direction of the net-like article in a state communicating over both the sides of the net-like article.
