Fabric.
The present invention provides a kind of and has irregular multilayer knitted fabric, at least 2 kinds that do as one likes matter is different
Yarn is constituted, it is characterised in that
Possess:
Woven and at the knitted fabric weaving after-contraction by the 1st yarn that shrinkage is of a relatively high；And
The knitted fabric woven by the 2nd yarn that shrinkage is relatively low,
By described 1st yarn braiding knitted fabric with by described 2nd yarn braiding knitted fabric that
This is relative and interconnected and constitutes multilayer knitted fabric,
Knitted fabric by described 1st yarn braiding and the knitted fabric by described 2nd yarn braiding are even
Tie and have in shrinkage difference, thus become recessed by the knitted fabric of described 1st yarn braiding,
Become convex by the knitted fabric of described 2nd yarn braiding,
And part 1 and part 2 configure adjacent to each other, in described part 1, by
The knitted fabric of described 2nd yarn braiding shows as convex in the face side of multilayer knitted fabric, and many
The reverse side of layer knitted fabric is shown as recessed by the knitted fabric of described 1st yarn braiding, and the described 2nd
In part, the knitted fabric of described 2nd yarn braiding show as in the reverse side of multilayer knitted fabric
Convex, and multilayer knitted fabric face side by described 1st yarn braiding knitted fabric show as recessed.
1st yarn and the 2nd yarn can be all to shrink yarn, but in order to increase the difference of shrinkage factor
Different, the preferably the 1st yarn is for shrinking yarn, and described 2nd yarn is non-constricted yarn.Pulled down yarn
In line, there is the low and easily flexible elastomeric yarn of elastic modelling quantity similar with elastomeric yarn and remove
The yarn of crispaturaing can crispaturaed after removing tension force, the thermal contraction yarn etc. shunk because of heating.This explanation
In book, if yarn of crispaturaing is contained in elastomeric yarn, be used for weaving by elastomeric yarn, then due to
The tension force that applies elastomeric yarn from loom, stretches with elastomeric yarn, and knitted fabric also stretches
State weaves.And by multilayer knitted fabric after loom unloads, by elastomeric yarn weave knitting
Thing shrinks.Be used for weaving by thermal contraction yarn, heating after braiding and after making its thermal contraction, by
The knitted fabric of thermal contraction yarn braiding shrinks.Herein by the pin shrinking the 1st yarn braidings such as yarn
Fabric is interconnected, therefore with by the 1st with by the knitted fabric of the 2nd yarn braidings such as non-constricted yarn
The knitted fabric of yarn braiding becomes recessed, the knitted fabric of the 2nd yarn braiding become convex mode and produce
Raw concavo-convex.Therefore the elastic force of the yarn being inserted between the knitted fabric of positive and negative it is independent of,
To having irregular multilayer knitted fabric.And as shown in Fig. 4, Fig. 6, Fig. 7, multilayer knitted fabric
Possessing the most concavo-convex, resiliency and aeration are high.In multilayer knitted fabric, convex reverse side is
Recessed, recessed reverse side is convex, the thin and light amount of multilayer knitted fabric self.And need not making positive and negative
The knitted fabric in face pushes the link yarn expanded and inserts, it is possible to weave and braid efficiency at short notice
High.
In the present invention, the knitted fabric of the 2nd yarn braidings such as non-constricted yarn become convex, by receiving
The knitted fabric of contracting yarn etc. the 1st yarn braiding becomes recessed, on the positive and negative two sides of multilayer knitted fabric
Show concavo-convex.And at the recess that the summit of the protuberance of face side is adjacent with protuberance with in face side
The end between interval become the concavo-convex difference of height in multilayer knitted fabric.Therefore the present invention is many
Layer knitted fabric can increase concavo-convex difference of height.The face side being located at multilayer knitted fabric becomes convex
Part be part 1, becoming recessed part in face side is part 2, part 1 with
Part 2 is adjacent one another are.Part 1 and part 2 can be in the row sides of knitted fabric
The most adjacent, it is also possible to adjacent one another are on stringer direction, or can also be in row
The both sides in direction and stringer direction are adjacent one another are.If double in row direction and stringer direction
Side is adjacent one another are, and the most such as surrounding of part 1 becomes part 2, around part 2
Become part 1.In contrast, in most of existing space fabrics, the reverse side of protuberance
The knitted fabric of side is formed flatly, or also forms protuberance at the knitted fabric of the reverse side of protuberance,
Therefore to obtain the difference of height identical with the present invention, need bigger protuberance.
Preferably, described 1st yarn is for shrinking yarn, and described 2nd yarn is non-constricted yarn
Line, is passed through to link by the knitted fabric shrinking yarn braiding and the knitted fabric woven by non-constricted yarn
Yarn links.Linking in yarn, if being shunk by the knitted fabric shrinking yarn braiding, then making by non-constricted
The knitted fabric of yarn braiding correspondingly deforms, and thus produces concavo-convex.
It is made up of it is further preferred that link yarn thermal welding yarn, and by shrinking yarn braiding
On knitted fabric and the knitted fabric that woven by non-constricted yarn, welding has link yarn.This have concavo-convex
Multilayer knitted fabric in, by shrinking the coil of knitted fabric of yarn braiding and being compiled by non-constricted yarn
The all weldings of the coil of the knitted fabric knitted have thermal welding yarn.Even if therefore will have irregular multilayer
Knitted fabric also will not be decoherenced with arbitrary shape severing, coil.Therefore after need not after severing
Process.
Preferably, described 1st yarn is for shrinking yarn, and described 2nd yarn is non-constricted yarn
Line, collects to the knitted fabric woven by non-constricted yarn from by the knitted fabric shrinking yarn braiding
Circle, or carry out to by the knitted fabric shrinking yarn braiding from the knitted fabric woven by non-constricted yarn
Tuck, thus by by the knitted fabric shrinking yarn braiding and the knitted fabric woven by non-constricted yarn
Link.Collection is passed through by the knitted fabric shrinking yarn braiding and the knitted fabric woven by non-constricted yarn
Enclosing and link, if therefore being shunk by the knitted fabric shrinking yarn braiding, then being compiled by non-constricted yarn
The knitted fabric knitted also deforms, and produces concavo-convex.Not linking yarn just can be by by shrinking yarn braiding
Knitted fabric and the knitted fabric that woven by non-constricted yarn link, therefore, it is possible to enter at short notice
The braiding of row multilayer knitted fabric.It is particularly preferred that utilize thermal welding yarn to constitute by non-constricted
The knitted fabric of yarn braiding.
If utilizing non-resilient and that thermal contraction is few thermal welding yarn to constitute link yarn or non-constricted yarn

Detailed description of the invention
Below, it is shown that for the optimum embodiment carried out an invention.
[embodiment]
Embodiment
In Fig. 1～Fig. 9, it is shown that the weaving method having irregular multilayer knitted fabric of embodiment
With the concavo-convex mechanism of generation and the photo of multilayer knitted fabric.Additionally, formation will at least be had just
The layer of face knitted fabric and formed reverse side knitted fabric layer, and these front knitted fabrics and reverse side knitting
The knitted fabric that thing is concatenated is referred to as multilayer knitted fabric.In order to by knitting to front knitted fabric and reverse side
In the case of thing links and arranges the layer linking yarn, become the multilayer knitted fabric of 3 layers.Multilayer pin
Fabric is not limited to 2 layers or 3 layers, it is also possible to be more than 4 layers.Fig. 1 illustrates initial embodiment
The weaving method of multilayer knitted fabric and loom on the structure of multilayer knitted fabric.Such as before using
After at least there is the straight-bar machines of a pair needle-bar or there is the circular weaving machine of inside and outside a pair needle-bar, braiding is many
Layer knitted fabric.Multilayer knitted fabric is by repeatedly performing the knitted fabric 4 that braiding is woven by inelastic yarn
Step S1, step S2 of knitted fabric 5 that woven by elastomeric yarn of braiding and braiding by collection
Enclose tuck step T of the layer 6 linking yarn linked by knitted fabric 4,5 and weave.
Elastomeric yarn means the yarn being rich in retractility, such as with by the fiber structure of non-telescoping
The yarn that the core being made up of the fiber that retractility is high is covered by the sheath become.If applying tension force, then core
Elongation, sheath around extends corresponding to the elongation of core, therefore elastomeric yarn elongation.Non-resilient
Yarn is the yarn that retractility is low compared with elastomeric yarn, by cotton thread, wool or common conjunction
Fiber yarn etc. is become to constitute.On loom during crochet needle fabric, if at the supply side of yarn to yarn
Line applies friction, or makes the minimizing etc. compared with the length of yarn of natural length of the quantity delivered of yarn,
The tension force then putting on yarn increases.Utilize this tension force, during braiding multilayer knitted fabric, to elasticity
Yarn applies tension force.And on the basis of natural length, make elastomeric yarn such as with 50%～100%
Degree of stretch and weave.The knitted fabric woven by elastomeric yarn is held in the needle-bar of loom, therefore
Till unloading from needle-bar, keeping the state of stretching, if unloading from needle-bar, shrinking.Non-resilient
The retractility of yarn is low, shows greatly natural length and directly weaves.If therefore unloading from the needle-bar of loom
Lower multilayer knitted fabric, then the knitted fabric 5 woven by elastomeric yarn is such as compiled with by inelastic yarn
The knitted fabric 4 knitted is compared, and length is shunk with 30%～50% degree.The layer 6 linking yarn is to pass through
Tucks etc. are by the knitted fabric 4 woven by inelastic yarn and the knitted fabric 5 woven by elastomeric yarn
The layer linked.
Elastomeric yarn and yarn of crispaturaing are all to stretch due to tension force on loom, if unloading from loom
Under the yarn that then shrinks, act on identical.Therefore can also replace elastomeric yarn and use crinkled yarn
Line.Thermal contraction yarn is the yarn shunk because of heating, if heating after braiding, shrinks, because of
This can also replace elastomeric yarn and use thermal contraction yarn, heats and make it shrink after braiding.
Thermal welding yarn is the yarn of welding because of heating, different from thermal contraction yarn.Shrink if using
Yarn and non-constricted yarn, then can increase the difference of both shrinkage factors, therefore, it is possible to formed
Big is concavo-convex.But it is also possible to replace non-constricted yarn and use the relatively small contraction of shrinkage factor
Yarn, the contraction yarn combination relatively large with shrinkage factor.
The knitted fabric 4 woven by inelastic yarn and the knitted fabric 5 woven by elastomeric yarn are to scheme
Unit 8 shown in 2 is unit, and the coil number of every regulation occurs in front to which knitted fabric
Side is exchanged.The coil number of unit 8 is not necessary for constant, and unit 8 is along multilayer knitted fabric
Stringer direction, can weave in the way of the position in row direction is mutually different, it is also possible to
Weave in the way of the position in row direction is constant.Herein, row direction be
Weaving the direction of multilayer knitted fabric on needle-bar, stringer direction is horizontal with coil on multilayer knitted fabric
The direction that column direction is vertical.And the layer 6 linking yarn is in 1 unit 8, passes through tuck
Link Deng by the knitted fabric woven by inelastic yarn 4 and the knitted fabric 5 woven by elastomeric yarn.
Do not linked by the layer 6 of link yarn between adjacent unit 8,8.
In Fig. 2, multilayer when illustrating that the needle-bar from loom unloads with the amount of 1 unit 8 is knitting
The deformation of thing 2.The arrow of Fig. 2 illustrates the process that unit 8 deforms.Unload from the needle-bar of loom
During multilayer knitted fabric 2, elastomeric yarn the knitted fabric 5 woven shrinks.Further, by elastomeric yarn
Knitted fabric 5 and the knitted fabric 4 woven by inelastic yarn of line braiding utilize the layer 6 linking yarn
Link, therefore with the knitted fabric 5 that woven by elastomeric yarn for recessed, inelastic yarn weave
Knitted fabric 4 is convex mode, produces concavo-convex on the positive and negative two sides of multilayer knitted fabric 2.Concavo-convex
Reason be from loom tension force disappear, the knitted fabric 5 therefore woven by elastomeric yarn shrinks,
Thus, elastomeric yarn the knitted fabric 5 woven becomes recessed part.In same unit 8 by
The knitted fabric 4 of inelastic yarn braiding is longer than the knitted fabric 5 woven by elastomeric yarn, therefore becomes
For convex.By linking the layer 6 of yarn, the knitted fabric of positive and negative is concatenated, multilayer knitted fabric 2 self
Thickness little.Also, it is not necessary to knitted fabric 4,5 will be made to push expansion round about
Yarn as link yarn layer 6 insert, therefore the braiding of multilayer knitted fabric 2 than patent document 1,
2 is easy.
The situation that requirement multilayer knitted fabric 2 has the most harder tension force is more.Such as use
In supporter, guard member, protection gloves etc. in the case of, or for chair seat surface,
In the case of mat, the guard member of pipe, package etc., multilayer knitted fabric 2 need concavo-convex not
The rigidity of the degree easily flattened.Even if applying, owing to having, the character that external force also keeps concavo-convex,
Therefore, it is possible to be used as supporter, guard member, the gloves etc. of protection.Even if owing to having applying
Body weight also keeps concavo-convex character, if therefore for the seat surface of chair, backrest, used for vehicle
