Abstract

The present invention discloses an extensible flexible hose comprise one elastic inner layer, one elastic textile reinforcement layer and one elastic outer layer, where the elastic textile reinforcement layer placed on the outer surface of the elastic inner layer, the elastic outer layer disposed on the elastic textile reinforcement layer, while the elastic inner layer and the elastic textile reinforcement layer are reciprocally coupled, the elastic outer layer and the uncovered surface area of the elastic inner layer are reciprocally joined to form a unitary tubular member. The elastic textile reinforcement layer comprising a twill weave textile layer, with stretch yarns longitudinally distributed among. The objective of the present invention is to improve the phenomenon that the telescopic water pipe is liable to be damaged due to strong friction between inner core and outer sheath, to prolong the service life of the extensible flexible hose. The hose body adopts elastic materials, which has advantages as great elasticity, easy carrying, easy cleaning, and convenient storage.
