Abstract:

To provide a bag body for civil engineering work by using a fiber, including a biomass-derived polymer in at least a part not on a synthetic fiber composed only of a conventional petroleum-derived polymer, being environment-friendly such as reducing a carbon dioxide generating quantity, and capable of compensating for a defect such as abrasion resistance inferior in the biomass-derived polymer by comparing with the petroleum-derived polymer.

This bag body for the civil engineering work is formed of knitted cloth composed of composite fiber. The composite fiber presents a core sheath shape in a cross section, and a sheath part is formed of a petroleum-derived all-purpose polymer, and a core part is formed of the biomass-derived polymer.
