Scope

Scope: This document specifies the identification method for polypropylene filament spun-bonded needle-punched nonwoven geotextiles. This document is applicable to the identification of polypropylene filament spun-bonded needle-punched nonwoven geotextiles (hereinafter referred to as filament geotextiles) and polypropylene staple fiber needle-punched nonwoven geotextiles (hereinafter referred to as staple fiber geotextiles). Main technical content: Filament geotextiles and staple fiber geotextiles differ in their production raw materials and processing methods, with significant differences in fiber morphology and mechanical properties. This document distinguishes polypropylene geotextiles from polyester geotextiles by measuring the fiber composition of the samples, observing the fiber morphology of the samples under an optical microscope, and measuring the tear strength per unit area of the samples to distinguish filament geotextiles from staple fiber geotextiles.
