Detailed description of the invention
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 2, for the first embodiment of the present invention, a kind of sleeve pipe 100a, in hollow tubular, there is thermal contraction structure, the axial direction fibre line 1 that this thermal contraction structure is made up of heat-shrinkage material and radial fiber line 2 are interweaved and form, and axial direction fibre line 1 has different shrinkage ratios along its length.Axial direction fibre line 1, radial fiber line 2 are parallel to axis and the radial direction of sleeve pipe 100a respectively.
At least one in heat-shrinkage material preferred PE, EVA, EPDM or PET.Refer to Fig. 3, axial direction fibre line 1 can be identical materials A with the heat-shrinkage material of radial fiber line 2, also can be different materials A and material B.In order to give the stronger intensity of material, shrinkage and resistance to ag(e)ing, heat-shrinkage material after being made into filament, all by crosslinking with radiation process.
Thermal contraction structure is interweaved in length and breadth by braiding machine or cross interleave axial direction fibre line 1 and radial fiber line 2 form.Axial direction fibre line 2 can be made up of one or more groups filament, group number number depend primarily on the size that axial direction fibre line 1 covers the coverage rate of product surface, when needing larger coverage rate, then many group filaments are selected to be twisted into an axial direction fibre line 1, otherwise otherwise.Radial fiber line 2 also can be made up of one or more groups filament, and filametntary group of number is how many, depends primarily on the size of required tension stress, as needed larger tension stress then to select many group filaments to be twisted into a radial fiber line 2, otherwise otherwise.
For the predetermined manner of the shrinkage ratio of axial direction fibre line 1, the present embodiment realizes by giving axial direction fibre line 1 stress different in the longitudinal direction when spinning machine (not shown) produces axial direction fibre line 1.Because spinning machine having multiple towing area, axial direction fibre line 1 is subject to the traction of different towing areas simultaneously, and meanwhile, the rotating speed because of for a change spinning machine can change the tractive force of towing area, so the rotating speed changing towing area can preset shrinkage ratio to axial direction fibre line 1.Such as, the rotating ratio of adjustment spinning machine first towing area and the 4th towing area is 1:5, and shrinkage ratio when axial direction fibre line 1 shrinks can reach 2:1; 1:8 is transferred to by rotating ratio, and shrinkage ratio when axial direction fibre line 1 shrinks can reach 3:1; 1:10 is transferred to by rotating ratio, and shrinkage ratio when axial direction fibre line 1 shrinks can reach 4:1.By reasonably presetting shrinkage ratio, the perfect contractive effect of thermal contraction structure predetermined patterns just accurately can be realized.
The production method of above-mentioned thermal contraction structure is as follows:
A, adopt spinning machine to produce axial direction fibre line 1 and radial fiber line 2 respectively, and in the process of producing axial direction fibre line 1, the rotating speed that adjustment spinning machine same district is not drawn, make axial direction fibre line 1 on length direction, have default different shrinkage ratios;
Axial direction fibre line 1 and radial fiber line 2 are interweaved together by b, employing braiding machine (not shown), form thermal contraction structure.
Sleeve pipe 100a in the present embodiment can be made into the heat-shrinkable tube 100a in hollow tubular when axial direction fibre line 1 and radial fiber line 2 weave by braiding machine.
Longitudinal, radial fiber line 1,2 that the thermal contraction structure of the present embodiment is made up of heat-shrinkage material are interweaved and form; and axial direction fibre line 1 has different shrinkage ratios along its length; so the sleeve pipe 100a be made up of it can follow when shrinking the contraction carrying out different shrinkage ratio according to the irregular profile of protected product 200; thus sleeve pipe 100a can touch the profile of product 200 tightly; for the comprehensive protection without dead angle in position is proposed at product 200 and irregular position thereof; because preventing sleeve pipe 100a that projection phenomenon occurs, thus save space to greatest extent.In addition, the structure of braiding mutually, can improve anti-pressure ability and the ABRASION RESISTANCE of sleeve pipe 100a, and the wall body of sleeve pipe 100a is not the structure of sealing, can be conducive to heat radiation.
As shown in Figures 4 and 5, for the second embodiment of the present invention, a kind of sleeve pipe 100b, there is the thermal contraction structure described in above-described embodiment one, after launching in the form of sheets, sleeve pipe 100b is interconnected by slide fastener 3 mode (referring to Fig. 4), Velcro 4 mode (referring to Fig. 5) or sewing machine suture way by thermal contraction structure dual-side along its length sleeve pipe in the present embodiment.When two ends that are longer when protected product 200 or protected product 200 are connected with larger connector; first the body of the sleeve pipe 100b of the present embodiment can be launched; to be wrapped after the periphery of product 200; by closed zipper 3, thread gluing Velcro 4 or the dual-side sewing up thermal contraction structure; closing product can be realized, easy to operate, quick.Avoid protected product 200 longer time sleeve pipe trouble, or after first will pulling down connection when the two ends of product 200 are connected with larger connector, put the trouble of mounted connector again after sleeve pipe 100b.
Referring to Fig. 6, is the third embodiment of the present invention, and a kind of sheet boundary belt 100c, has the thermal contraction structure in above-mentioned first embodiment, and sheet boundary belt 100c entirety in the form of sheets.The mode can be bumped into according to different environments for use, be wound around is wrapped on the surface of protected product 200, once the heating sheet boundary belt 100c just collapsible seal protection effect reaching expection.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
