Self-wound shielding sleeve and fabrication method thereof

Abstract

The invention relates to a self-wound shielding sleeve. The self-wound shielding sleeve is fabricated by curling and shaping a sheet-shaped weaving fabric, the weaving fabric is provided with two free edges extending along a longitudinal axis, the two free edges are self-curled to form curly states that the two free edges are overlapped under an effect of no external force, the two free edges can be converted to unfolded states under the effect of an external force and are restored to the curly states after the external force is removed, the weaving fabric is fabricated by warp yarns and weft yarns, the warp yarns are covering yarns comprising organic fiber and metal wires and / or metal wire strands, and the weft yarns comprises covering yarns and thermoplastic organic fiber. The invention also relates to a preparation method of the sleeve. The sleeve has the following advantages of lightness, good weaving performance, excellent puncturing-resistant strength, optical aging resistance, high-temperature resistance, scrapping resistance, mould prevention, water prevention and the like, is difficult to break and is particularly suitable for effectively protecting a tubular matter such as a cable and an optical cable under severe working conditions such as high temperature, high irradiation strength and electromagnetic signal interference.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a self-rolling shielding sleeve 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 generally two kinds of such protective sleeves: (1) a closed sleeve that adopts fiber braiding, and (2) an open sleeve that adopts fiber braiding. 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 ...

Problems solved by technology

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 main body of the sleeve, which reduces the weaving process; Chinese patent ZL201120438767.4 discloses a self-rolling sleeve, that is, it is self-curling along the radial direction of the sleeve to partially overlap each other, and can be It can be opened under the action of external force, just to protect the cable and facilitate the construction, but it has no anti-stab and shielding performance

At present, the number of wiring harnesses inside machines in various fields is increasing day by day, and there is an urgent need for protective sleeves with shielding functions to prevent mutual signal interference. Chinese patent ZL201310584056. Self-rolling sleeve, the sleeve has a shielding effect, but the weight of the sleeve is heavy after the plastic fiber wire and metal wire are woven together, and the breaking strength of the metal wire is low, so it is easy to break during the weaving process; After a complete set of pipe products, it is easy to be pierced by hard objects, which will cause damage to the protected object
