Abstract
The invention discloses a design principle and a manufacturing method of a flexible material with segmental deformation modulus and high strength, relates to fabric with segmental deformation modulus and high strength, and particularly relates to a flexible material different modulus and high strength of which in different deformation stages can be achieved by structural change characteristics in dynamic deformation processes by a structural design by utilization of fabric comprising materials with different modulus. According to the technical scheme, the fabric with segmental modulus is weaved from at least a material having a high tensile modulus and a material having a low tensile modulus. When the fabric is in the low-deformation stage, the fabric shows the low-modulus characteristics and is capable of maintaining the freedom of motion of human body joints and muscles. With the increase of the deformation, unbending, friction and transfer of the high-modulus material in the fabric are generated, and therefore the modulus of the fabric increases gradually. When the fabric is in the high-deformation stage, the fabric shows high-modulus characteristics and can effectively prevent injury caused by excessive tensile of the human body joints and muscles in sport processes.
Description

Product in above patent, mainly concentrates on protection human body and avoid from outside impact, but not protection sporter is because of the damage of the excessive tendon causing of displacement amplitude or ligament.Therefore how to reduce in motion is carried out, because the accident of stressed joint or muscle group causes impaired, urgently to be resolved hurrily that large deformation produces.
Summary of the invention
In order to solve above technical problem, the present invention has reported that a kind of development has design principle and implementation method that segmentation becomes modulus fabric.This fabric is in ascending deforming process, and modulus material from low to high participates in deformation process successively, makes causing that the needed external force of distortion has interim difference in different regions, thereby provides body little of large protection strength by having.Make to belong to little modulus distortion in certain deformation range, allow motion keep free and relaxed.When amplitude of deformation is excessive may cause when damage its deformation modulus become fast large and prevent stressed joint or muscle group due to dislocation or the damage that excessively stretches and cause.
Fig. 1 has shown change modulus flexible material design process.The technical solution adopted for the present invention to solve the technical problems is: adopt and at least need the braiding of the material of high/low two kinds of stretch moduluses to form segmentation modulus fabric.When fabric is in the low deformation stage, low-modulus material deformation bearing load.Now fabric presents low modulus characteristic.Namely, under little load condition, can reach larger distortion, thereby make motion process as far as possible free and relaxed.Along with deformation strengthens, fabric construction changes to be increased, and the high modulus material in fabric construction starts to occur stretching, rubbing and shifting between material, thereby the modulus of fabric is progressively increased.When fabric arrives the high deformation stage, high modulus material deformation bearing load.Now fabric presents high-modulus characteristic.Also realize under larger load, could realize less distortion, thereby play the injury gained in sports that prevents that excessive distortion from causing.
The invention has the beneficial effects as follows: the low deformation of distortion segmentation modulus fabric, low modulus characteristic, can effectively keep the freedom of motion of human synovial and muscle group.The high deformation of distortion segmentation modulus fabric, high-modulus characteristic, can effectively prevent the excessive stretching of human synovial and muscle group in motion process and the damage that causes.
Realize above-mentioned purpose, a kind of Design & preparation method within the scope of different distortion with the flexible material of different distortion modulus is reported in the present invention.Specific implementation technique comprises: realize the flexible material that becomes modulus, in this material, at least comprise two kinds of different modulus component materials, by structural design in dynamic deformation process, the distortion component material that is formed different modulus by structural change adds distortion stage by stage, thus realize different distortion in the stage material monolithic show different modulus and powerful characteristic.
The design of this material at least comprises two deformed regions, and it is respectively low modulus region and high-modulus region, and the percentage with stretcher strain amount represents respectively.The feature of this material area is the low deformation stage, and mainly by low-modulus material generation strain, and high modulus material, in relax stage, strain does not occur, so the distortion of fabric shows and has low modulus feature.
When this material enters high deformed region, namely high modulus material enters tensioning state by relaxed state, and the distortion of continuation makes high-modulus component material produce distortion, form high deformation modulus, so fabric has high-modulus feature together with low-modulus material.In design process, in this flexible material design, the slack of high-modulus component can be by the 50%-150% design of low modulus deflection, preferably 80-100%; This material can design by the selection of structure and material, thereby realizes the control of the conversion in fabric low modulus/high-modulus region.
Realize this material and realize distortion segmentation modulus function, can adopt various fabrics structure, comprising but be not limited to knitted structure, comprise 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 woven structure, comprise plain weave, the structure of twill and satin weave and their variations.
Fig. 2 has shown the basic theories model of this kind of change modulus flexible material design.Its core is that the material of two or more different modulus is participated in distortion with structure in parallel as spring.The modulus of final performance is high-modulus, low modulus and Research on Structural Modulus sum.Because the difference of material high-modulus low modulus is quite big, low modulus and Research on Structural Modulus can be simple in appropriate circumstances.Fig. 3 has shown the key in structural design, controls exactly the loose measure of high-modulus component material, and this loose measure must be consistent with the deflection of low-modulus material.Namely, high modulus material is relaxed state in giving the low modulus deformed region of setting, and strain does not occur.
