Flood prevention sandbag
The invention provides a flood prevention sandbag which comprises an outer bag and inclusions, the outer bag comprises at least two layers, at least one layer is a braided fabric formed by weaving regenerated cellulose narrow bands, and at least one layer is a fabric or a non-woven fabric. According to the flood prevention sandbag provided by the invention, the outer bag comprises the braided fabric formed by weaving the regenerated cellulose narrow bands, so that the outer bag can expand and become compact after absorbing water, and compared with a conventional fabric outer bag, the flood prevention sandbag has a better water blocking effect, and the water blocking capacity of the flood prevention sandbag can be further improved.
本发明提供了一种防汛沙袋，其包括外袋和内含物，所述外袋包括至少两层，其中至少一层为再生纤维素窄带编织而成的编织物，至少一层为织物或非织造布。本发明提供的防汛沙袋，外袋包含有由再生纤维素窄带编织而成的编织物，因此外袋吸水后会膨胀而变得致密，相比于常规的织物外袋具有更好的阻水效果，能进一步提升防汛沙袋的阻水能力。
