The pressure of tubing, cut, the research of shrinkage, dilatancy etc., but be not directed to it is provided by the present invention have radially contract
The pipe fabric of swollen function, especially it is not directed to a kind of rotated by friction unblock provided by the present invention and couples generation with structure phase in version
Pipe fabric radially collapsed and preparation method thereof.
The content of the invention
Problem to be solved by this invention is：One kind is provided inflection occurs along elongated straight pipe inside and outside wall under stretching action
The pipe fabric and its forming technique of high withdrawing smoothness and low tensile elongation when withdrawing moves.
The principle of the present invention be rotated by the friction unblock pushed up when swollen and extruding force acts in radial direction using intersecting lacing and
Fabric construction phase in version (i.e. yarn flexing and seating surface transformation) is coupled to strengthen being radially expanded for thin tube-like fabric (pipe fabric)
Or shrink, the elongation without influenceing radial direction yarn, i.e. the radial direction breathing of pipe fabric is unrelated with radial deformation, that is, the present invention does not have to
Radial deformation reaches the radial direction breathing of pipe fabric, it is ensured that low tensile elongation during withdrawing pipe fabric, while height can be realized
Withdrawing smoothness.
In order to solve the above problems, the radial direction contracting coupled with structure phase in version is rotated the invention provides a kind of unblock that rubs
Tube expansion fabric, it is characterised in that the pipe fabric is symmetrically to compile yarn with the intersection for having certain friction self-locking effect using low-angle
With the mode of the organizine asymmetrical braid of relatively partially thick, rigid and high warp tension, obtained Stability Analysis of Structures, axial stiffness, radial direction
Swell-shrink thin tube-like fabric.
Preferably, the two groups of yarns for compiling yarn that intersect are had using relatively partially thin fine-denier and twist with the fingers crimp filament yarn or length/short
Composite yarn, elongation at break are not less than 8%, and are the soft line elastomers of low stretch modulus and bending modulus.
It is highly preferred that the span for intersecting the angle of the crossing for compiling yarn is 60 °~90 °；The angle of the crossing (θ) is compiled with intersecting
The relation of the helical angle (φ) of yarn helix is：The φ of θ=180 ° -2.
It is highly preferred that described have the crimp filament twisted with the fingers in crimp filament yarn to refer to that crimp percent is no more than 10% and Curl
Rate is more than 80% high-performance endless tow；Long/short composite yarn refers to the short fine and high-performance long filament of high-performance through ring ingot Compound spinning
Into soft, high-elastic, low modulus composite yarn.
Preferably, for the organizine of the pipe fabric using high-strength and high-modulus optic filament through twisting the circular multifilament formed, it is height
The line elastomer of modulus, elongation at break are no more than 10%.
It is highly preferred that the long filament is used without the high-performance long filament of curling and elongation at break no more than 7%.
Preferably, during the withdrawing of the pipe fabric, organizine occurs linear elasticity and shrinks or stretch, and maximum flexibility is shunk
Amount is no more than 4%, and to ensure that flatness of the pipe fabric in axial direction is grown, maximal tensility is no more than 10%；Intersect compile yarn because curling and
There is sth. made by twisting to stretch naturally under low tension with bending without extending；Meanwhile between intersection volume yarn and its between organizine, because yarn body circle is cut
Face and be in relatively low intersection pivoting friction torque, easily under stretching action and unlock rotate and fork-shaped slide similar contraction；When
When pipe fabric is coated on circular tube external wall, under stretching action, pipe fabric is acted on by the top expansive force of circular tube external wall, in circular tube external wall
On intersection compile yarn the angle of the crossing (θ occur in intersection1) diminish (θ1＜ θ) intersection rotate, be radially expanded pipe fabric；Hand over
Fork compiles yarn itself and can stretch and increase, and pipe fabric is supported that the low-tension towards the structure phase through seating surface changes, that is, manages by latitude
The diameter of fabric is significantly increased, and diameter Magnification is not less than 3%, and both are combined so as to taking out when significantly reducing pipe fabric outer cladding
Pull out resistance；When pipe cloth furniture is in round tube inner wall, under stretching action, pipe fabric is acted on by the extruding force of round tube inner wall,
One, the intersection on round tube inner wall compile yarn because of the increase of tensile force, overcome the intersection pivoting friction torque for intersecting and compiling between yarn, and
The angle of the crossing (θ occurs by the center of circle of crosspoint2) become big (θ2＞ θ) intersection rotate, make pipe fabric produce radial contraction；Intersect and compile
Yarn makes pipe fabric by through supporting the structure phase in version towards latitude seating surface, i.e. pipe fabric can produce because the softness of itself bends
Raw significant radial contraction, shrinkage factor are not less than 7%, and both are combined so as to reduce withdrawing resistance when being extruded in pipe fabric.
The present invention also provides above-mentioned friction unblock and rotates the preparation side that the radial direction coupled with structure phase in version collapses pipe fabric
Method, it is characterised in that comprise the following steps：
Step 1)：Prepare organizine and intersect to compile yarn and upper machine；Fabric manufacture equipment uses circular knitting machine；
Step 2)：Organizine parallel arrangement is on circular knitting machine；
Step 3)：Two groups of yarns for intersecting volume yarn are intersected with identical but reverse helical angle, sequentially carried out with organizine
Braiding, obtain the radial direction that friction unblock rotation couples with structure phase in version and collapse pipe fabric.
Above-mentioned preparation method can be used for existing tubing can not be realized under stretching action along elongated straight pipe in preparing
Inside and outside wall has high withdrawing smoothness during inflection withdrawing, low tensile elongation and only diameter change pipe fabric to be woven into
Shape.
The radial direction coupled with structure phase in version is rotated present invention also offers above-mentioned friction unblock and collapses pipe fabric elongated
Banding samples the application in critical component or sample collection bag, suitable for space technology, geology investigation, archaeological discovery small bulk
Solid rock, the stratigraphical drilling sampling of soil sample and sample collection.
Compared with prior art, the beneficial effects of the present invention are：
1. pipe fabric construction exquisiteness stabilization, performance high-ductility Gao Mo, prepare conveniently；
2. there is high withdrawing and low tensile elongation；
3. as sample unit and sample collection bag in use, with higher sampling rate, original bedding information can obtain
Kept to preferable, and occur without sample phenomenon.
