WIDE-MESHED AGRICULTURAL AND CIVIL ENGINEERING CONSTRUCTION SHEET WHICH CAN BE SEAMED BY HIGH FREQUENCY

摘要

PURPOSE:To obtain a sheet which can be seamed by high frequency and has a high seam strength, by densely arranging the number of thread-like matters at a selvage at a periphery of a fabric sheet whereto a polymer having a high- frequency fusion property is adhered. CONSTITUTION:A polymer, such as a polyvinyl chloride urethane resin, an ethylene-vinyl acetate polymer, having a high frequency fusion property, is adhered to a sheet with a comparatively rough mesh of 225m2 or less which is formed such that thread-like matters having no high-frequency fusion property are arranged in directions of warp and woof. A selvage 2 at the periphery of the sheet is woven in a close texture being 2 times or more as densely as other part. In case the sheets are coupled together, the selvages 2 of the adjoining sheets are overlapped with each other for high-frequency seaming.
