摘要： The application relates to the technical field of wiring accessories, in particular to a protective tube. The protective tube includes a tube wall and fluffy warp yarns, wherein the tube wall forms a pipeline for a cable to be threaded therein and includes cross-woven first warp yarns and first weft yarns; the fluffy warp yarns are on an inner surface of the tube wall and are fluffier than the first warp yarns, the fluffy warp yarns are cross-woven with the first weft yarns and form a plurality of intersections with the first weft yarns, and each of the fluffy warp yarns spans a plurality of the first weft yarns between two adjacent intersections. When the protective tube is subjected to external impact, the tube wall with stronger hardness can protect the cable; moreover, the fluffy warp yarn reduce the friction between the protective tube and the cable.
