The definition of geotextile and geotextile and the relationship between the two

Geotextiles are defined as permeable geosynthetics in accordance with the national standard “GB/T 50290-2014 Geosynthetics Application Technical Specifications”. According to different manufacturing methods, it can be divided into woven geotextile and non-woven geotextile. Among them: there are woven geotextiles woven by fiber yarns or filaments arranged in a certain direction. Non-woven geotextile is a thin pad made of short fibers or filaments arranged randomly or oriented, and a geotextile formed by mechanical bonding and thermal bonding or chemical bonding.

Geotextiles are defined in accordance with the national standard “GB/T 13759-2009 Geosynthetics Terms and Definitions” as: a flat, filterable type used in contact with soil and (or) other materials in rock engineering and civil engineering A textile material composed of polymers (natural or synthetic), which can be woven, knitted or non-woven. Among them: woven geotextile is a geotextile composed of two or more sets of yarns, filaments, strips or other components, usually vertically intertwined. Non-woven geotextile is a geotextile made of oriented or randomly oriented fibers, filaments, strips or other components through mechanical consolidation, thermal bonding and/or chemical bonding.
It can be seen from the above two definitions that geotextiles can be considered as geotextiles (that is, woven geotextiles are woven geotextiles; non-woven geotextiles are non-woven geotextiles).
