The invention discloses a hose capable of being flattened. The hose capable of being flattened comprises an inner rubber layer, an outer rubber layer and a cylindrical fabric layer which is positioned between the inner rubber layer and the outer rubber layer, wherein the inner rubber layer and the outer rubber layer are made of a thermoplastic polyurethane or polyvinyl chloride material; the cylindrical fabric layer comprises an outer enhancement layer and an inner enhancement layer; the outer enhancement layer and the inner enhancement layer are of independent plain, twill or satin weave structures which are formed by weaving warp yarns and weft yarns; the outer enhancement layer and the inner enhancement layer are bound by using the weft yarns. The invention also provides a manufacturing method of the hose capable of being flattened. The hose capable of being flattened can bear high conveying liquid pressure to further improve the conveying flow of the hose; the hose capable of being flattened has good softness under a storage condition and is convenient to coil or fold to store.
