Abstract
PURPOSE:To obtain a draining material having high water permeability and high pressure resistance by a method in which the recessions of a synthetic resin core are fitted with the projections of lapped nonwoven fabrics. CONSTITUTION:Many parallel grooves 2 are formed in one direction on a synthetic resin core 1. A nonwoven fabric material 3 formed by hot-bonding 20wt.% or more hot-bonding fibers and 80wt.% or less is laminated on the grooved 2 face of the core 1, where the projections of the nonwoven fabrics 3 are fitted into the grooves 2 of the core 1 to combine the fabrics 3 and the core 1. A draining material free of blocking of water-permeable portion even when used for long periods can thus be obtained.
