Background technique
The advantages of based on lightening, flexible and Portable belt, at present flexible wearable electronic device by extensive concern and
Research, and flexible wearable electronic device but electric energy supply be the weight for influencing current flexible wearable development of electronic devices and application
Want factor.
Friction nanometer power generator combines triboelectrification and electrostatic induction, can effectively will be various in ambient enviroment
Mechanical energy, such as the kinetic energy that human body generates during exercise are converted to electric energy, and structure is simple, and material is extensive, are current relatively more clear
Clean energy conversion device is expected to become the ideal powering device of wearable electronic device.
But traditional friction nanometer power generator frequently with multilayered structure, such as blocky or membrane structure exists and is not easy
In being stretched, reversing and the defect of wearable property and softness difference, it is difficult directly to match with wearable electronic device, no
Suit large area to popularize application.
Compared to traditional friction nanometer power generator, the friction nanometer power generator for constructing textile structural, which can satisfy, now may be used
The be expected to good flexibility having, moving situation flexible, that adapt to human body and performance of wearable device energy supply device is stablized
The advantages that, the friction nanometer power generator for constructing textile structural is conducive to the development and extensive use of wearable electronic device.Currently,
Although there is many researchers to study two-dimensional fabric base friction nanometer power generator, as plain weave structure generate electricity fabric, due to
Fabric construction limitation, if the number of plies is less or warp and weft contact area is smaller, keeps its electricity output performance generally lower, therefore be difficult
To good application and promote.
Three-dimensional angle-interlock fabric is multiple latitude (multiple warp) angle interlocking woven fabric abbreviation, it is the yarn structure by two systems
At the intertexture of overlapping interlocking shape.It is overlapped when warp thread is constituted in fabric thickness direction (Z-direction), then weft yarn is existed with certain inclination angle
X-direction and the multiple chain shape in angle that carried out interweave；It is overlapped conversely, working as weft yarn and being constituted in fabric thickness direction (Z-direction), then warp thread
Angle interlocking shape is carried out in X-direction and multiple latitude with certain inclination angle to interweave.According to the yarn system for constituting overlapping, can be divided into
It is multiple to interlock two kinds through angle interlocking and multiple latitude angle.Three-dimensional angle-interlock fabric only contains relative to other three-dimensional woven fabrics
Two systems, deformability is stronger, and warp and weft contact area is larger；Three-dimensional angle-interlock fabric is relative to two-dimentional woven fabric, the number of plies
More, warp and weft contact area is larger.Friction nanometer power generator such as, which is made, in three-dimensional angle-interlock fabric will be expected to solve current two
The lesser problem of fabric base friction nanometer power generator warp and weft contact area is tieed up, the electricity output performance of generator is significantly improved.
Therefore, the three-dimensional angle-interlock power generation fabric and preparation method thereof for studying a kind of electricity output function admirable has very heavy
The meaning wanted.
Summary of the invention
It is existing in the prior art since fabric construction limitation leads to fabric base friction nanometer the purpose of the present invention is overcoming
The electricity output performance of generator is poor and then is difficult to the problem of being applied and being promoted well, provides a kind of three-dimensional angle-interlock hair
Electric fabric and preparation method thereof.The present invention uses matrix of the three-dimensional angle-interlock woven fabric as friction nanometer power generator, due to three
Dimension Angular interlocking structure is multilayered structure, conventional two-dimensional fabric is substantially better than on the thickness direction of fabric, and due to three dimensional angular
Interlock is only made of two yarn systems, is had relative to the three-dimensional woven fabric being made of three yarn systems easily deformable
And the characteristics of can increase the contact area between warp and weft, thus three-dimensional angle-interlock power generation fabric of the invention can have good electricity
Output performance.
To reach above-mentioned purpose, The technical solution adopted by the invention is as follows:
A kind of three-dimensional angle-interlock power generation fabric, for the three-dimensional angle-interlock fabric being made of two yarn systems, two yarns
System is respectively warp systems and weft systems, and weft systems are located at the left or right side of warp systems, perpendicularly into thread layer, warp
The composition yarn of yarn system and weft systems is different, and composition yarn is that mechanical energy acquires yarn or compliant conductive yarn, both can be with
Be warp systems is made of mechanical energy acquisition yarn, and weft systems are made of compliant conductive yarn, be also possible to weft systems by
Mechanical energy acquires yarn composition, and warp systems are made of compliant conductive yarn, and two schemes are all within the scope of the present invention,
All yarns are all identical in warp systems, and all yarns are all identical in weft systems, slightly different to be applied equally to this
The main reason for invention, design yarn is all identical is to guarantee electricity output performance, and the radical that mechanical energy acquires yarn is more, electricity
Output performance is better, therefore when warp systems or weft systems are using mechanical energy acquisition yarn, preferably whole yarns are all machine
