WIPO Patent Application WO/2023/217169
Kind Code:

Abstract:
A hose, comprising a hose body, the hose body consisting of an inner TPE rubber layer (1), a middle TPE layer (2), an outer TPE rubber layer (3), a fiber layer (4) and a spandex layer (5), the spandex layer (5) being arranged between the inner TPE rubber layer (1) and the middle TPE layer (2), the fiber layer (4) being arranged between the middle TPE rubber layer and the outer TPE rubber layer (3), the fiber layer (4) being fiber yarns wound around the hose, the fiber layer (4) being spirally wound around the middle TPE rubber layer, the spandex layer (5) consisting of a plurality of spandex yarns, the spandex layer (5) being arranged outside the inner TPE rubber layer (1) in the length direction of same, and the three TPE rubber layers, the fiber layer (4) and the spandex layer (5) being fused into a whole. For the hose of the above structure, because of high elasticity of the spandex yarns, after the hose is supplied with water and swells, the hose can extend in the length direction so that the hose is greatly lengthened; the fiber layer (4) is arranged in a manner of spirally winding fiber yarns, and thus does not limit extension in the length direction of the hose, and the fiber layer is wound around the hose rubber layer in a surrounding mode so that the anti-burst performance of the hose can be enhanced; and after water supply is cut off, the hose greatly contracts, thus reducing the storage size and facilitating storage.
