Abstract
The present invention entitled flexible material design principle and preparation method with subsection deformation modulus and strength, it is related to a kind of fabric for having and modulus and strength being segmented in deformation, espespecially a kind of fabric formed using different modulus material, can be in dynamic deformation process by structure design, realized by the characteristic of structure change has a kind of flexible material of different modulus and strength in the different distortion stage.The technical scheme is that：Segmentation modulus fabric is knitted to form using the material of high/low two kinds of stretch moduluses is at least needed.When fabric is in low deformation phase, in low modulus characteristic, the freedom of motion of human synovial and muscle group can be effectively kept.As deformation increases, the high modulus material in fabric construction starts to occur stretching, rub and shifting between material, so that the modulus of fabric incrementally increases.When fabric reaches high deformation phase, in high-modulus characteristic, the damage that can effectively prevent the excessive tensile of human synovial and muscle group in motion process and trigger.
Description
Technical field
It is espespecially a kind of to use different modulus material the present invention relates to a kind of fabric for having and modulus and strength being segmented in deformation
Expect the fabric of composition, can be realized by structure design in dynamic deformation process by the characteristic of structure change in different distortion
There is a kind of flexible material of different modulus and strength in stage.
Technical background
With the improvement of living standards, people are also increasingly paid close attention to the health of own bodies, sport and body-building also or it is more or
Few daily life into everyone, but the damage of thing followed body kinematics has also brought great puzzlement.Cause
This research and development one kind can be protected body kinematics joint and move the fabric of muscle group in motion process, make joint and motion muscle group
It can use and easily move within the specific limits, and can provides a kind of intellectual material of appropriate protection when overstepping the extreme limit
As the concern target of industry.

Product in above patent, it is concentrated mainly on and protects human body from the impact from outside, and non-protected sporter
Because of the damage of displacement amplitude is excessive and triggers tendon or ligament.Therefore how to reduce in motion is carried out, due to stress
The accident of joint or muscle group causes large deformation and caused impaired, it would be highly desirable to solves.
The content of the invention
In order to solve the above technical problems, the present invention reports a kind of design principle developed and become modulus fabric with segmentation
And implementation method.For the fabric in ascending deformation process, modulus material from low to high participates in deformation process successively, makes
Must to cause deformation required for external force have in different regions stage difference, so as to provide body by have it is small to greatly
Protect strength.So that belonging to small modulus deformation in certain deformation range, motion is allowed to keep free and relaxed.When amplitude of deformation is excessive
Its deformation modulus during damage may be caused quickly to become big and prevent stress joint or muscle group from triggering due to dislocation or excessive tensile
Damage.
Fig. 1, which is illustrated, becomes modulus flexible design of material process.The technical solution adopted for the present invention to solve the technical problems
It is：Segmentation modulus fabric is knitted to form using the material of high/low two kinds of stretch moduluses is at least needed.When fabric is in low deformation rank
Section, low-modulus material deformation simultaneously bear load.Now low modulus characteristic is presented in fabric., can namely under small load condition
To reach larger deformation, so that motion process is as far as possible free and relaxed.As deformation increases, fabric construction change increase, knit
High modulus material in thing structure starts to occur stretching, rub and shifting between material, so that the modulus of fabric is progressively
Increase.When fabric reaches high deformation phase, high modulus material deformation simultaneously bears load.Now high-modulus characteristic is presented in fabric.
Realize under larger load, less deformation could be realized, prevent motion caused by excessive deformation from damaging so as to play
Wound.
The beneficial effects of the invention are as follows：The low deformation of deformation segmentation modulus fabric, low modulus characteristic, can effectively keep human body
Joint and the freedom of motion of muscle group.The high deformation of deformation segmentation modulus fabric, high-modulus characteristic, can effectively prevent motion process
The excessive tensile of middle human synovial and muscle group and the damage triggered.
Realize above-mentioned purpose, a kind of design of the flexible material with different distortion modulus in the range of different distortion with
Preparation method is reported in the present invention.Specific implementation technique includes：The flexible material for becoming modulus is realized, in the material
Including at least two kinds of different modulus component materials, by structure design in dynamic deformation process, difference is formed by structure change
The deformation component material of modulus adds deformation stage by stage, and so as to realize, material general performance goes out different moulds in the different distortion stage
Amount and forceful nature.
The design of this material comprises at least two deformed regions, and it is low modulus region and high-modulus region respectively, is distinguished
Represented with the percentage of stretcher strain amount.The material area is characterized in low deformation phase, and bullet mainly occurs by low-modulus material
Property deformation, and high modulus material is in the relaxation stage without elastic deformation occurs, therefore the deformation of fabric shows have low mould
Measure feature.
When the material enters high deformed region, that is, high modulus material enters tensioning state by relaxed state, continuation
Deformation is deformed high-modulus component material, high deformation modulus is formed together with low-modulus material, therefore fabric has height
Modulus feature.The slack of high-modulus component can be by low modulus deflection in flexible material design in the design process
50%-150% is designed, preferably 80-100%；The material can be designed by the selection of structure and material, so as to realize that fabric is low
The control of the conversion in modulus/high-modulus region.
Realize the material realize deformation segmentation modulus function, various fabrics structure can be used, including but do not limit to
In knitted structure, including single side weft-knitting structure, double side weft knitting structure, single needle bed warp knit structure, two-needle bar warp knit structure；Also can adopt
With woven structure, including plain weave, twill and satin weave and the structure of their changes.
Fig. 2 illustrates the basic theories model that this kind becomes modulus flexible design of material.Its core is two or more
The material of different modulus participates in deformation with the structure of parallel connection as a spring.The modulus finally showed is high-modulus, low modulus and
Research on Structural Modulus sum.Because the difference of the low modulus of material high-modulus is quite big, modulus low in appropriate circumstances and structure mould
Amount can be simple.Fig. 3 illustrates the key in structure design, exactly controls the loose measure of high-modulus component material, the loose measure with
The deflection of low-modulus material must be consistent.It is, high modulus material is in pine in the low modulus deformed region to setting
Relaxation state, does not occur elastic deformation.
