Beschreibung
Zusammenfassung:	Disclosed is A water pipe with synchronously retractable multi-layer, comprising: a retractable inner pipe 30; a fabric sleeve 10 sleeved outside the inner pipe 30, which is configured as a retractable cylindrical or corrugated one- or multi-layer fabric sleeve formed by interweaving retractable elastic yarns arranged at intervals in the axial direction and non-retractable reinforcing yarns arranged at intervals in the circumferential direction; and a retractable plastic film layer 20 interposed between the inner pipe 30 and the fabric sleeve 10. According to the present disclosure, the inner pipe 30, the plastic film layer 20 and the fabric sleeve 10 can be synchronously retracted under the effect of water pressure change, so that the frictional damage among multiple layers is effectively reduced, and the service life of the entire retractable water pipe is prolonged.
