Content of the invention
In this context, task of the invention is, proposes a kind of knitted spaced fabric with the beginning feature, described
Knitted spaced fabric being capable of easy to manufacture and with good functional characteristic.A kind of interval pin being consequently formed should additionally be proposed
Fabric section and the heated covering element with this knitted spaced fabric section.
The solution of subject of the present invention and the task is knitted spaced fabric according to claim 1, according to right
Require 7 knitted spaced fabric section and heated covering element according to claim 11.
Described knitted spaced fabric sets out from the outset, according to present invention provide that, conducting yarns cated synthesize material by setting
Material multifilament threads constitute, have less than 250dtex fineness and in the first knitted fabric layer at least two coil files with
Band yarn (Legung) is woven together and preferably alsos form coil, and in above-mentioned conducting yarns, conductive coating levels are less than
50 (weight) %, preferably 15 (weight) %, especially preferred each long filament for being less than 5 (weight) %. multifilament threads are non-conductive, therefore not
Conductive core can be formed.Coated encirclement distinguished by each long filament, and keep moving relative to each other.Conducting yarns are in appearance
Similar to metallic cable (at least in the case where there is metal coating), but the spy of fundamental difference is had based on core cover structure
Property.
In scope of the invention, particularly importantly conducting yarns prolong in band yarn at least two coil files
Stretch, and therefore adjacent coil file is conductively connected, then produce in corresponding knitted fabric layer in whole knitted spaced fabric
Raw conducting surface. here, conducting yarns preferably also form coil, this is according to scope of the invention and non-imposed needs.
Can also for example specify, conducting yarns are woven at least two coil files becomes part inlaid thread, and in extension in a zigzag,
And itself does not form coil. as another kind of yarn system, then can also for example adopt in the first knitted fabric layer according to
Chaining band yarn figure, the yarn extended only along coil file. the yarn of this other yarn system not only could be designed without
Conduction, and may be designed as conduction.
Even if in the case of being provided with the relatively large content up to 50 (weight) % in metal coating, on each long filament
Thickness is higher also based on the density of coating and holding is relatively small.By the core of filament form so that conducting yarns keep very high
Movement and deformability.
According to prior art, metallic cable or be provided with metal coating monofilament lines relatively hard and therefore, it is difficult to processing,
And according to the present invention, be material of the conducting yarns setting less than the relative thin of 250dtex, additional, cause the conduction being hardened
Coating relative thin and relative to synthetic material silk thread content be less than 50 (weight) %.
The characteristics of synthetic material multifilament threads, first consists in higher compared to the monofilament lines using identical material manufacture fortune
Dynamic property.Coil can easily be formed in scope of the invention unexpectedly, although the synthetic material multifilament threads as core
Movement is high and conducting yarns are bent substantially when each coil is formed, and conductive coating is still remained intact.Conductive
Outer cover of the coating on each long filament usually as circumference closing, although therefore substantially bending also can be by the outer of this closing
Cover form ensures enough resistances of coating. conductive coating can deform to a certain extent, but will not be in synthesis material
Peel off in material multifilament threads or from synthetic material multifilament threads.
In scope of the invention, can be by with the coating for realizing conduction in the way of different.
According to the first flexible program, involved is metal coating, especially it is contemplated that have good corrosion resistance and
There is the metal or metal alloy of certain deformability.Additionally, to also consider the conducting yarns with metal coating into
This. such as conducting yarns can have a metal coating based on silver, and silver can be deformable well and with relatively good resistance to
Resistance. exactly in the case where the weight content of metal coating is little, although the cost of coating is relatively high, in a lot of applications
Or economic use may be realized.Although a disadvantage is that the silver on surface also can form thin oxide layer, the oxide layer according to should
Uneven contacting or uneven electric current may be caused to a certain extent with situation.
For example it is also contemplated that the lower copper of use cost substitutes silver, then can be excluded with institute in no instance
State the surface oxidation of shortcoming.In addition can also be using gold as metal coating, to avoid described shortcoming, but cost will be obvious
It is higher.
According to the present invention a kind of alternate embodiments, using nonmetallic coating. especially it is contemplated that using graphite or its
Its material based on carbon, then can generally avoid the formation of undesirable oxide layer.Additionally, being the characteristics of graphite relatively good
Movement.In principle, however, it is also possible to consider using other nonmetallic coatings, however, it is also possible to according to the side of conductive paint
Formula or the analog based on polymer form nonmetallic coating.
Finally, the coating of multilayer is also possible in principle. and for example can be by different metal levels also or non-metallic layer phase
Mutually combine, to realize for corresponding applicable cases are optimal in terms of electric conductivity and electrical contact on the surface on the one hand
Coupling.It is contemplated that acetyl for example by the laminated coating plating with the internal layer being made up of copper or silver on thin gold coating.
If the embodiment of the conducting yarns that cated synthetic material multifilament threads are constituted not only directly during braiding,
And during subsequent arrangement be all important.Apply temperature when arranging, wherein, textile material is so heated, made
Obtain each yarn and although long filament will not melt but can be eliminated as yarn is at interval by the viscous flow of polymer chain
Stress in the yarn for bending in the coil of knitted fabric and producing.Synthetic material yarn is primarily based on internal stress and just returns to which
Good original form, and these stress are eliminated by arranging, then by cooling down the bending in knitted fabric after arrangement
State " is freezed " to a certain extent. and according to the present invention, each long filaments for being preferably respectively provided with coating of synthetic material multifilament threads is one
To determine also move relative to each other in degree, during manufacture and arrangement, thus realize more preferable machinability. metal coating is proper
Just advantage can be produced when arranging, because heat can be well conducted to long filament by coating.
Although the first knitted fabric layer of planar includes conducting yarns, knitted spaced fabric flexible relative and have comfortably
Feel. according to the present invention, can as far as possible using the known weave pattern of non-conductive knitted spaced fabric, then part or complete
Complete utilization conducting yarns form the first knitted fabric layer of planar.
As it was previously stated, silver is preferably provided with metal coating, then will stand relatively high material cost for metal coating.
Silver has that conducting power is good, little corrosion tendency and the characteristics of good deformability. in view of these characteristics, can be according to should
Metal coating is designed to situation very thin, then metal coating only has the shadow of little share to the mechanical property of conducting yarns
Ring.Generally, being hardened of causing of metal coating can be remained little.
In scope of the invention, weight portion of conductive, especially metal the coating relative to the gross weight of conducting yarns
Volume be preferably smaller than 15 (weight) %, for example between 1 (weight) % and 5 (weight) %.
According to the present invention, conducting yarns have a fineness less than 250dtex, the fineness preferably in 90dtex and
Between 200dtex.Fineness can for example be used for the conducting yarns of 110dtex or 145dtex.

For the other embodiment of the first knitted fabric layer, forming different enforcements in scope of the invention may
Property, but generally each conducting yarns is connected in the way of directly making electrical contact with the conducting yarns that at least one is other.Electricity
Contact can be realized according to weave pattern.In the simplest situations, for example adjacent conducting yarns can be mutual by warp knit band yarn
Connection, but it is also possible to consider any other band yarn mode, wherein, conducting yarns are directed simultaneously at least two coil files
And local is intersected with each other.
In scope of the invention, conducting yarns can be arranged in the first knitted fabric layer comprehensively.Then, when setting conduction
When yarn is as unique yarn system, but the first knitted fabric layer is only made up of the conducting yarns. it is also possible that by
The first knitted fabric layer constituted as the conducting yarns of the first yarn system and the second yarn system is made up of non-conductive yarn,
For this purpose, the first knitted fabric layer of planar correspondingly can be formed using two or more yarn guiding chase combs.
Furthermore, it is possible to the first knitted fabric layer has the conductive bars extended along production mode reform, then conducting yarns are only
