Problems solved by technology

However, the casing disclosed in the above-mentioned patent will age after being exposed to sunlight or space environment during use, causing the warp yarn to be damaged, thereby affecting the protective effect of the casing; in addition, the existing self-rolling casing adopts the current Fibers are woven as warp yarns, and there are problems such as poor puncture resistance

Abstract

The invention relates to a self-rolling sleeve which is prepared by crimping and shaping a sheet-like woven fabric. The woven fabric is provided with an opposite first free edge and a second free edgeextending along a longitudinal axis; the first free edge and the second free edge are in a curled state without external force, and can be separated from each other under the action of external forceto be in an open state; the first free edge and the second free edge are restored to the curled state after the external force is removed; the woven fabric is obtained by warp and weft knitting of warp yarns and weft yarns; at least one type or part of the warp yarns and weft yarns is polyimide fibers; the weft yarns are more thermoplastic with respect to the warp yarns and comprise thermoplasticorganic fibers. The invention also relates to a method for manufacturing the self-rolling sleeve. The self-rolling sleeve provided by the invention has excellent performance such as light aging resistance, high temperature resistance, puncture resistance and the like, can be mildewproof, waterproof and scratch-resistant, and is light in weight, simple in structure, convenient to install and repair, easy for industrialization production, and especially suitable for effectively protecting tubulars, such as cables, optical cables and the like, under severe 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...
