Description
Technical field
The device of thick, soft high-elastic yarn preparation auxetic composite yarn, method are actively wound the present invention relates to a kind of thin, hard low yarn that plays
And purposes.
Background technology
Auxetic materials refer to the material with negative poisson's ratio, i.e., be stretched in one direction relative to traditional material
When (or compression), it can produce contractions (or expansion) perpendicular to force direction and deform, auxetic materials in one direction by
During stretching (or compression), it can produce expansion (or contraction) deformation perpendicular to force direction.Auxetic yarn is also known as negative pool ratio
Yarn, under certain axial tension effect, the increase of yarn radial contour.Research finds that auxetic materials, which are removed, has negative poisson's ratio
Outside, compared with traditional material, also with other special performances, such as shearing rigidity, fracture toughness, pressure mottling resistance, energy absorption energy
Power (ultrasonic wave, sound, damping) etc. is all increased, and potential application is respectively provided with each field：Auto industry (cushion, safety belt),
Aero-Space (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 and manufacturing process of auxetic yarn cause great concern, and many scholars are carried out to it
Desk study and research.Patent WO2007/125352A1, patent US2011/0209557A1, patent 2011/0039088A1
It is proposed a kind of negative poisson ratio yarn structure being wrapped over by rigid yarn spiral on the heart yarn of easy elongation strain, its 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 produced, causes heart yarn to bend, causes yarn diameter to increase.It is related to the description to negative poisson ratio yarn structure in patent,
Do not suggest that specific spinning apparatus and method, and the yarn texture easily there are problems that twist irregularity and.Patent
The negative poisson ratio yarn structure being related in WO2010/146347A1 is that non-extensible fine rule spiral is extended through into relatively thick and bullet
Property larger component in, under axial tension effect, fine rule, which is stretched, causes outsourcing material flexing to produce auxetic effect, and 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 manufacture method.The yarn texture by by the first larger yarn of stretch modulus and stretch modulus compared with
The second small yarn it is spaced and meanwhile feed slotted eye, and under the rotation of rotating disk converge twisting form negative poisson's ratio yarn, when
When being stretched effect, two groups of yarns are mutually extruded because modulus difference produces relative transfer, so as to reach Negative poisson's ratio.Should
Method requires that the first yarn and the second yarn radical are identical and more than 2, because 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, the selection limitation to yarn variety is strong, while also limiting
The application field of negative poisson's ratio yarn is made.
One is given in Donghua University's week inscription master thesis " structure formation of negative poisson's ratio yarn and modeling are characterized "
The specific spinning apparatus of negative poisson's ratio yarn and method are planted, and a series of researchs have been done to spinning process, passes 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.Should
Not enough to the yarn road controling power of fasciated yarn using the front roller of fluting in spinning apparatus, there is looping angle in the negative pool of gained than yarn
And structure it is irregular the problems such as.
Therefore the spinning apparatus and method of existing auxetic composite yarn are also immature, there is that yarn texture is irregular, Yarn spinning method
Limitation is strong, the problems such as be unsuitable for continuous production.
