Abstract: PURPOSE:To obtain a sheet for civil engineering excellent in durability and hardly deteriorating the strength even under severe conditions such as high- temperature alkaline water. CONSTITUTION:The sheet for civil engineering is characterized as a mesh sheet knitted or woven from yarn, composed of core-sheath type conjugate continuous filament having a sheath component composed of at least one selected from a polyolefinic resin, a polyacrylic resin, a melamine resin, a urea resin, a fluorine-based resin and a polyamide-based resin and coated with a synthetic resin film.

Abstract: PURPOSE: To provide a net for temporal construction that has excellent strength, durability and flame retardancy by using polyester fiber that contains a specific amount of a difunctional phosphorus compound, comprises polyester mainly including ethylene terephthalate units having specific physical properties. CONSTITUTION: The objective net is made of polyester fibers that contain a difunctional phosphorus compound (suitably 1,2-dimethylphosphine oxide or the like) in an amount of 0.2-1.0 wt.% calculated as elementary phosphorus, a polyester of which >=85 wt.% recurring units are ethylene terephthalate, has an intrinsic viscosity of >=0.65, a strength of >=6.0 g/d, and a yarn fineness of 200-800 deniers. The density of the fibers constituting the objective net is optimally 1.39 g/cm and the optical birefringence is >=135×10 . The objective net has semipermanent flame retardance, the fabric hand is soft and the dry cleaning can be applied thereto.
