▎ 摘　　要

NOVELTY - An electroconductive textile comprises textiles incorporated with graphene. USE - Electroconductive textile is used as layer in multi-layer construction, used for inspection process to determine integrity of water barrier (claimed). The textiles are used as protective layers when building water retention facilities (e.g. dams and ponds) or water guidance facilities (e.g. drainage and canals). ADVANTAGE - The electroconductive textile provides a reliable mechanism for inspection of barrier liners in water retention applications, than the existing methods. The method provides a way to test the sheet for defects, such as holes, via the electrical properties incorporated in the sheet by the presence of graphene. Graphene is efficiently dispersed in the textiles to achieve the required electroconductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) multi-layer construction incorporating the textile; and (2) method of inspecting the integrity of a water barrier containing multi-layer sheet. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an inspection circuit used to detect defects in a multi-layer sheet that acts as a barrier layer. Barrier layer (1) Clay base (2) Inspection probe (3) Voltage or current source (4) Earth contact (5)
