Title:
ROOF SUBSTRATE
Document Type and Number:
Japanese Patent JPH10280623
Kind Code:
A
Abstract:

To provide an antiskid property without degrading a waterproofing property physical strength, a nail hole water stopping property and moisture permeability by applying a resin to one side of nonwoven fabric for forming a plurality of spot type resin projections and filament type projections.

A resin is applied to at least one side of nonwoven fabric made by the flash spinning method using polyolefine resin, thereby providing a plurality of spot type resin projections 4 and 4 formed like scattering and made independent of each other. In this case, a plurality of rows of filament type projections 5 and 5 are preferably formed approximately in parallel with the end of the nonwoven fabric. More preferably, the resin is applied to a side different from a side having the projections 4 and 5, thereby forming a plurality of filament type projections 5 approximately in parallel with the end of the nonwoven fabric. Thus, a high antiskid property is provided without degrading a high waterproofing property, physical strength, a nail hole water stopping property and humidity permeability.
