Embodiment
In order that technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Drawings and Examples are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
As shown in Fig. 2 being the first embodiment of the present invention, a kind of sleeve pipe 100a, in hollow tubular, with thermal contraction knot
Structure, the axial direction fibre line 1 and radial fiber line 2 that the thermal contraction structure is made up of heat-shrinkage material is interweaved and formed, axially
Single 1 has different shrinkage ratios along its length.Axial direction fibre line 1, radial fiber line 2 are respectively parallel to sleeve pipe 100a
Axially and radially.
At least one of heat-shrinkage material preferred PE, EVA, EPDM or PET.Refer to Fig. 3, axial direction fibre line 1 and footpath
Can be identical materials A or different materials As and material B to the heat-shrinkage material of single 2.In order to assign material
Stronger intensity, shrinkage and the resistance to ag(e)ing of material, heat-shrinkage material after filament is fabricated to, by crosslinking with radiation at
Reason.
Thermal contraction structure is interweaved in length and breadth by braider or cross interleave axial direction fibre line 1 and radial fiber line 2 are formed.Axle
Can be made up of to single 2 one or more groups of filaments, group number number depend primarily on the covering product table of axial direction fibre line 1
The size of the coverage rate in face, when needing larger coverage rate, then selects multigroup filament to be twisted into an axial direction fibre line 1,
Otherwise it is on the contrary.Radial fiber line 2 can also be made up of one or more groups of filaments, and how much is filametntary group of number, depends primarily on
The size of required tension stress, then selects multigroup filament to be twisted into a radial fiber line 2, otherwise if desired for larger tension stress
It is on the contrary.
For the predetermined manner of the shrinkage ratio of axial direction fibre line 1, the present embodiment in spinning-drawing machine (not shown) by giving birth to
Give the stress different in the longitudinal direction of axial direction fibre line 1 to realize during production axial direction fibre line 1.It is multiple because having on spinning-drawing machine
Towing area, axial direction fibre line 1 is drawn by different towing areas simultaneously, meanwhile, it can change because changing the rotating speed of spinning-drawing machine
Become the tractive force of towing area, so, shrinkage ratio can be preset to axial direction fibre line 1 by changing the rotating speed of towing area.For example, adjustment is spun
The rotating ratio of the silk towing area of machine first and the 4th towing area is 1：5, shrinkage ratio when axial direction fibre line 1 shrinks can reach 2：1；
Rotating ratio is transferred to 1：8, shrinkage ratio when axial direction fibre line 1 shrinks can reach 3：1；Rotating ratio is transferred to 1：10, axial direction fibre line 1 is received
Shrinkage ratio during contracting can reach 4：1.By reasonably presetting shrinkage ratio, so that it may accurately realize thermal contraction structure predetermined patterns
Perfect contractive effect.
The production method of above-mentioned thermal contraction structure is as follows：
A, produce axial direction fibre line 1 and radial fiber line 2 respectively using spinning-drawing machine, and in production axial direction fibre line 1
During, the rotating speed that adjustment spinning-drawing machine is not drawn on same district makes axial direction fibre line 1 in having default difference on length direction
Shrinkage ratio；
B, using braider (not shown) axial direction fibre line 1 and radial fiber line 2 are interweaved together, shape
Into thermal contraction structure.
Sleeve pipe 100a in the present embodiment when braider weaves axial direction fibre line 1 and radial fiber line 2 i.e.
The heat-shrinkable tube 100a in hollow tubular can be fabricated to.
Longitudinal direction that the thermal contraction structure of the present embodiment is made up of heat-shrinkage material, radial fiber line 1,2 are interweaved and formed,
And axial direction fibre line 1 has different shrinkage ratios along its length, so the sleeve pipe 100a being made from it can be when shrinking
With according to the contraction that different shrinkage ratios are carried out by the irregular profile of protection product 200, so that sleeve pipe 100a can tightly touch production
The profile of product 200, is that product 200 and its irregular position propose the comprehensive protection without dead angle in position, because preventing sleeve pipe 100a to send out
Raw projection phenomenon, so as to save space to greatest extent.In addition, the structure mutually woven, can improve the anti-of sleeve pipe 100a
Pressure energy power and wearability, and sleeve pipe 100a wall body is not sealed structure, can be conducive to radiating.
As shown in Figures 4 and 5, it is the second embodiment of the present invention, a kind of sleeve pipe 100b, with institute in above-described embodiment one
In the thermal contraction structure stated, the present embodiment sleeve pipe expansion after in the form of sheets, sleeve pipe 100b by thermal contraction structure along its length
Two sides mutually interconnected by the mode of slide fastener 3 (referring to Fig. 4), the mode of VELCRO 4 (referring to Fig. 5) or sewing machine suture way
Connect.When protected product 200 is longer or the two ends of protected product 200 are connected with larger connector, can first by
The sleeve pipe 100b of the present embodiment body expansion, it is to be wrapped after the periphery of product 200, pass through closed zipper 3, thread gluing VELCRO
4 or suture two sides of thermal contraction structure, you can realize closing to product, it is easy to operate, quick.Avoid protected production
Sleeve pipe is bothered when product 200 are longer, or the two ends of product 200 first will be pulled down after connection when being connected with larger connector, put
The trouble of installs connector again after sleeve pipe 100b.
Fig. 6 is referred to, is the third embodiment of the present invention, a kind of sheet protection band 100c, with above-mentioned first embodiment
In thermal contraction structure, and sheet protection band 100c is overall in the form of sheets.It can be bumped into according to different use environments, wound
Mode is wrapped in by the surface of protection product 200, and once heating, sheet protection band 100c is just collapsible to reach expected sealing
Protective effect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
