Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only
It is that a part of the embodiment of the present invention is not intended to limit the protection scope of the present invention instead of all the embodiments.
Fig. 1 is please referred to, Fig. 1 is the structural schematic diagram for cutting out water droplet sensor fabric of one embodiment of the invention.Fabric
Main body is vertically interwoven using more non-conductive warp thread 1 and non-conductive weft yarn 2, and conductive warp yarns 201,202 are spaced apart
It is woven into fabric, entire fabric there also is provided many such conductive warp yarns along warp thread direction.On the left of the fabric at selvedge, it is provided with
2 conductive warp yarns 101,102 are separated by non-conductive warp thread 1 between them.When first conductive warp yarns 201 is woven into, passed through with conduction
Yarn 101 normally interweaves, and contacts with each other, electrically conducts；Completely cut off and be electrically insulated by insulating cement 3 with conductive warp yarn 102.Second
When conductive warp yarns 202 are woven into, completely cut off and be electrically insulated by insulating cement 3 with conductive warp yarn 101；It is normally handed over conductive warp yarn 102
It knits, contacts with each other, electrically conducts.Other conductive warp yarns are also woven into according to the rule of conductive warp yarns 201,202 by root on fabric, this
Sample conductive warp yarn 101 is connected with odd number root conductive warp yarns, and conductive warp yarn 102 is connected with even number root conductive warp yarns, conductive
Warp thread 101,102 is mutually not turned on when normal.
In addition, when conductive warp yarns and conductive warp yarn are completely cut off by insulating cement, it is conductive such as conductive warp yarns 201 and conductive warp yarn 102
For warp thread 102 under, it is above insulating cement 3, then is above conductive warp yarns 201, and the purpose being arranged in this way is to facilitate production.Specifically
Production process is: being woven into before conductive warp yarns 201, with the brush brush conductive warp yarn 102 for speckling with insulating cement, conductive warp yarn 101 is not
It deals with, is then normally woven into conductive warp yarns 201 when conductive warp yarn 102 is in below shed open, then just form conductive warp yarns
201 contact with each other with conductive warp yarn 101, electrically conduct, and are mutually isolated, are electrically insulated with conductive warp yarn 102.
Referring to figure 2., Fig. 2 is the operation principle schematic diagram shown in FIG. 1 for cutting out water droplet sensor fabric.When there is water on fabric
Drop 9 in the presence of, non-conductive warp, weft yarn in region, which can absorb water, becomes able to conduction, conductive warp yarn 101,102 thus be connected,
Guiding path is 202 → conductive warp yarn of conductive warp yarn 101 → conductive warp yarns, 201 → water droplet, 9 → conductive warp yarns 102.It will be apparent that this
In embodiment, conductive warp yarn 101,102 is used as leadout electrode, and conductive warp yarns 201,202 are used as detecting electrode, according to leading when use
Whether electric warp thread 101,102, which is connected i.e., can determine whether that whether there is or not water droplets on fabrics cloth cover.
Referring to figure 3., Fig. 3 is shown in FIG. 1 to cut out the structural schematic diagram after water droplet sensor fabric is cut out.Work as Fig. 1
In fabric cut out along broken line AB after, fabric shown in Fig. 3 is obtained, due to cutting out rear leadout electrode i.e. conductive warp yarn 101,102 still
So retain, therefore fabric still has detection function.Guiding path is 101 → conductive warp yarns of conductive warp yarn, 203 → water droplet 9 in figure
202 → conductive warp yarn of → conductive warp yarns 102.
Referring to figure 4., Fig. 4 is the structural schematic diagram for cutting out water droplet sensor fabric of another embodiment of the present invention,
In increase conductive warp yarn.When in Fig. 1 in 2 conductive warp yarns of fabric one be broken when, then the detection function of entire fabric
It can lose, therefore several conductive warp yarns can be set more.It is provided with 4 conductive warp yarns in Fig. 4, is respectively positioned on fabric the same side selvedge,
2 groups inside and outside being divided into, inside group is that contact or isolation situation of the conductive warp yarn 102,104,104 with conductive warp yarns are identical as 102；Outside
Side group is that contact or isolation situation of the conductive warp yarn 101,103,103 with conductive warp yarns are identical as 101.In this way, even if 4 conductions
1 or inside and outside group each fracture 1 is broken in warp thread, the detection function of entire fabric will not be lost, to increase in use
Stability.Moreover, such as conductive warp yarn quantity is further promoted, such as promoted to 6,8,10 ..., 20, i.e., every group
3,4,5 ..., 10, then stability can be improved more.But increasing for conductive warp yarn will will increase the difficulty of production, because
Need to brush more insulating cements, so conductive warp yarn radical is suitable at 10 or less.
Referring to figure 5., Fig. 5 is the structural schematic diagram for cutting out water droplet sensor fabric of further embodiment of this invention,
Middle fabric is equipped with conductive warp yarn.Fabric in Fig. 1, Fig. 4 can cut out use, but can only use containing leadout electrode be
The part of conductive warp yarn, i.e. left-half, but right half part uses but due to not having leadout electrode without having detection function
In can only give up, cause a degree of waste.Fig. 5 is provided with 4 conductive warp yarns, and left side is still 101,102, and right side is then to lead
Electric warp thread 111,112.When being woven into first conductive warp yarns 201, respectively with left side conductive warp yarn 101, right side conductive warp thread 111
It is normal to interweave, thus contact with each other and be electrical connected with left side conductive warp yarn 101, right side conductive warp thread 111, while being led with left side
Electric warp thread 102, right side conductive warp thread 112 are completely cut off and are electrically insulated by insulating cement 3；Second conductive warp yarns 202 and conductive warp
The case where yarn contact or isolation, is with first conductive warp yarns 201 on the contrary, being and left side conductive warp yarn 102, right side conductive warp thread 112
It contacts and is electrical connected, while is simultaneously electrically exhausted by the isolation of insulating cement 3 with left side conductive warp yarn 101, right side conductive warp thread 111
Edge.In this way, conductive warp yarn 101,102 constitutes left side leadout electrode, conductive warp yarn 111,112 constitutes right side leadout electrode.It uses
When, it is only necessary to whether be connected according to the leadout electrode of wherein side, i.e. conductive warp yarn 101,102 or conductive warp yarn 111,112
Whether conducting can determine whether that whether there is or not water droplets on fabrics cloth cover.
After Fig. 5 fabric is tailored along broken line AB, obtained left-half is the fabric in Fig. 3, can normal use；It obtains
Right half part be then fabric in Fig. 6, still can be used normally.
To increase stability when using, prevent detection function caused by being broken because of conductive warp yarn from losing, the left and right sides is conductive
Warp thread can increase as figure 4, such as setting 8,12,16 ..., 40 conductive warp yarns, i.e., every side 4,6,8 ..., 20；
Every side be further divided into it is two groups inside and outside, every group 2,3,4 ..., 10.
When obviously, using above-described embodiment, fabric can arbitrarily be cut out without influencing to use, and fabric can be with opposite side
Just processed production；Higher stability can be realized when using more conductive warp yarns；More conductions are provided with using two sides
The structure of warp thread, then left and right two halves part can be used after detection can be achieved, and avoid waste.
The present invention is disclosed with preferred embodiment above, so it is not intended to limiting the invention, all to take equivalent replacement
Or the scheme technical solution obtained of equivalent transformation, it falls within the scope of protection of the present invention.
