Abstract

The invention relates to a self-rolling sleeve, which is made by crimping and shaping a sheet-like woven fabric; In the crimped state, they can be separated from each other into an open state under the action of an external force, and the first and second free edges return to a crimped state after the external force is removed; the woven fabric is made by warp and weft weaving by warp and weft; at least one of the warp and weft One is at least partially a polyimide fiber; the weft yarns are more thermoplastic relative to the warp yarns and comprise thermoplastic organic fibers. The invention also relates to a method of manufacturing said self-rolling sleeve. The self-winding sleeve of the present invention has excellent light aging resistance, high temperature resistance, puncture resistance and other properties, can be mildew-proof, waterproof, scratch-resistant, light in weight, simple in structure, convenient for installation and maintenance, and easy for industrialized production. It is especially suitable for effectively protecting cables, optical cables and other tubular objects under harsh working conditions.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a self-rolling casing and a preparation method thereof. Background technique [0002] Braided protective sleeves are widely used in the protection of tubular objects, such as wire harnesses and cables in the fields of automobiles, ships, and aerospace. At present, there are usually two types of protective sleeves: (1) closed sleeves that are braided with fibers. (2) Fiber braided open casing is used. The first type of bushing is inconvenient to disassemble and install when the protected object breaks down or needs to be overhauled. The second casing avoids this shortcoming. Chinese patent ZL201220377807.3 discloses a self-adhesive sleeve, which uses unwoven multifilament to replace the velcro surface of the existing sleeving, and wraps the object by forming a bond between the multifilament and the velcro hook surface , there is no need to set the buckle surface on the m...
