Description
Technical field
The present invention relates to a kind of thin, hard low yarns that plays actively to wind the device of thick, soft high-elastic yarn preparation auxetic composite yarn, method
And purposes.
Background technique
Auxetic materials refer to the material with negative poisson's ratio, i.e., are stretched in one direction relative to traditional material
When (or compression), contractions (or expansion) can be generated perpendicular to force direction and deformed, auxetic materials in one direction by
When stretching (or compression), expansion (or contraction) deformation can be generated perpendicular to force direction.Auxetic yarn is also known as negative and moors ratio
Yarn, under certain axial tension effect, yarn radial contour increases.The study found that auxetic materials, which remove, has negative poisson's ratio
Outside, compared with traditional materials, also there are other special performances, such as shearing rigidity, fracture toughness, pressure mottling resistance, energy absorption energy
Power (ultrasonic wave, sound, damping) etc. all increases, and all has potential application in each field: auto industry (cushion, safety belt),
Aerospace (wing plate, radome fairing), physical protection (helmet, knee-pad, gloves), biomedical (artificial blood vessel, suture, intelligence
Can textile), other field (filtering material, sensor, sonar unit) etc..
In recent years, the structure design of auxetic yarn and manufacturing process cause great concern, and many scholars carry out it
Desk study and research.Patent WO2007/125352A1, patent US2011/0209557A1, patent 2011/0039088A1
The negative poisson ratio yarn structure being proposed on a kind of heart yarn for being wrapped over easy elongation strain by rigid yarn spiral, wherein patent
The Negative poisson's ratio for the material that 2011/0039088A1 is proposed is the looping long filament to humidity sensitive when outer moisture changes
Contraction is generated, causes heart yarn to be bent, yarn diameter is caused to increase.It is related to the description to negative poisson ratio yarn structure in patent,
Specific spinning apparatus and method are not suggested that, and the yarn texture easily has the problems such as twist irregularity and stability.Patent
The negative poisson ratio yarn structure being related in WO2010/146347A1 is that non-extensible filament spiral is extended through to relatively thick and bullet
Property biggish component in, under axial tension effect, filament, which stretches, causes outsourcing material buckling to generate auxetic effect, this structure is steady
It is qualitative preferably, but Yarn texturing is limited causes Negative poisson's ratio smaller.Patent CN2013/103361811A proposes a kind of negative
Poisson's ratio yarn texture and its manufacturing method.The yarn texture by by biggish first yarn of stretch modulus and stretch modulus compared with
The second small yarn is spaced while feeding slot, and convergence twisting forms negative poisson's ratio yarn under the rotation of turntable, when
When being stretched effect, two groups of yarn mutual extrusions opposite transfer because modulus difference generates, to reach Negative poisson's ratio.It should
Method requires the first yarn and the second yarn radical identical and at 2 or more, since the yarn texture is mainly by each group
The twisting divided acts on being formed, therefore in order to provide the shaped structure of yarn, strong to the selection limitation of yarn variety, while also limiting
The application field of negative poisson's ratio yarn is made.
One is given in Donghua University's week inscription master's thesis " structure formation and modeling characterization of negative poisson's ratio yarn "
The specific spinning apparatus of kind negative poisson's ratio yarn and method, and a series of researchs have been done to spinning process, pass through preceding sieve of fluting
The negative poisson's ratio yarn of spinning spiral looping structure is drawn, and experiment test and theory analysis have been carried out to the Poisson's ratio of yarn.It should
Insufficient using yarn road control force of the front roller of fluting to fasciated yarn in spinning apparatus, there are looping angles than yarn for the negative pool of gained
And structure it is irregular the problems such as.
Therefore the spinning apparatus of existing auxetic composite yarn and method are also immature, there are yarn textures irregular, Yarn spinning method
Limitation is strong, is unsuitable for the problems such as continuous production.
