Description
Technical field
The present invention relates to new material technology fields, and in particular to a kind of self-rolling shielded tube and preparation method thereof.
Background technique
Braiding class protection sleeve pipe is widely used in the protection of tube, for example, the fields such as automobile, ship, aerospace
Harness, cable etc..There are two types of current this protection sleeve pipe is usual: (1) using the closed sleeve of fibrage, (2) are using fine
Tie up the split coupling of braiding.For the first casing when protected object breaks down or needs to overhaul, disassembly and installation are not
It is convenient.Second of casing then avoids this disadvantage.Chinese patent ZL201220377807.3 discloses a kind of self-adhering type casing,
The thread gluing hair side that existing casing is substituted using the multifilament without braiding is formed bonding by multifilament and sticking button hook surface and realized to object
The cladding of body no longer needs to that thread gluing hair side is arranged in pipe sleeve main body, reduces weaving process；Chinese patent
ZL201120438767.4 discloses a kind of Self-crimping type sleeve, i.e., overlaps each other along the radial part that is curled into certainly of casing, and
Can be openable under external force, only play the role of protecting cable and facilitate construction, but there is no anti-stab and shielding properties.
Currently, the harness quantity inside each field machine is increasingly huge, it is badly in need of the protection sleeve pipe with function of shielding, anti-stop signal is mutual
Interference, Chinese patent ZL201310584056.1 is using PET monofilament, PA monofilament or PPS monofilament and wire plying through knitting device
At Self-crimping type sleeve, which has shielding action, but after plastic cellosilk and wire the plying braiding used, casing
Weight is big, and in addition the breaking strength of wire is low, easily broken during braiding；Moreover, being easy after weaving into set tubing products by hard object
It pierces through, and then causes protected object impaired.
Summary of the invention
To solve the above-mentioned problems, first aspect present invention provides a kind of self-rolling shielded tube, it is characterised in that:
The self-rolling shielded tube is crimped by sheet braided fabric and is shaped and be made；
The braided fabric has opposite the first free margins and the second free margins extended along the longitudinal axis of described sleeve pipe,
And it is curled into the rolled state that first free margins and second free margins overlap each other certainly under no external force,
Under external force first free margins and second free margins can be transformed into from the rolled state to overlap each other
Separated opening state, and first free margins and second free margins revert to the volume after the external force is removed
Curved state；
The braided fabric is using warp thread and weft yarn by being made through knitting device；
The warp thread is for first covering yarn of (a) containing the first organic fiber and the first wire and/or (b) by third gold
Belong to the wire plying that silk is formed；
The weft yarn includes second covering yarn of (c) containing the second organic fiber and the second wire and (d) thermoplasticity has
Machine fiber.
Second aspect of the present invention provides a kind of method for manufacturing self-rolling shielded tube described in first aspect present invention,
Described method includes following steps: (1) providing the braided fabric；(2) the plasticizing temperature of the thermoplastic organic fiber in weft yarn
The degree lower curling braided fabric, then cooling shaping, is made the self-rolling shielded tube.
The function of shielding of self-rolling shielded tube of the invention is realized by the covering yarn comprising organic fiber and wire
, or realized jointly by wire plying with the covering yarn containing organic fiber and wire.This kind of covering yarn braiding
At casing woven with pure metal silk and metallic fiber is compared with the casing that is woven into of organic fiber plying, have following excellent
Point: metalolic network can be formed to reach the metal mesh phase with pure metal net and the plying braiding of metallic fiber and organic fiber
With shield effectiveness while, considerably reduce the weight of self-rolling shielded tube；(2) weft yarn comprising wire is improved
Knitting property, be not easily broken；(3) being folded without breaking intensity is high.In addition, self-rolling shielded tube of the invention also have it is following excellent
Point: (4) have excellent light aging resisting property and/or high temperature resistance；(5) there is good mould proof waterproof performance；(6) have
Excellent scrape abrasion resistance energy；(7) structure is simple, can be rapidly assembled and disassembled, and is convenient to install and examine without tool
Repair casing and protected object therein；(8) it is easy to industrialization production；(9) particularly suitable in high temperature, irradiation intensity height, electromagnetism
The tubes such as cable, optical cable are effectively protected under the conditions of the bad working environments such as signal interference.
