In-situ braided expandable hose and braiding method thereof

Abstract

A method for in-situ braiding an expandable hose includes: S1, arranging N groups of elastic filaments in a stretched state in parallel along a circumferential direction of an elastic inner tube in a stretched state on an outer wall of the elastic inner tube; and with each group of elastic filaments corresponding to two groups of braiding yarns, conducting figure-8 braiding with braiding yarns around the elastic inner tube to braid the N groups of elastic filaments in the stretched state successively onto the outer wall of the elastic inner tube in the stretched state to produce the expandable hose with a braided layer; and S2, releasing the expandable hose obtained in the S1 while the elastic inner tube is synchronously rotated and tensioned to enable retraction of the expandable hose to a natural state, and winding.
