Background technology
Sewing thread is the suture material in fabrics for industrial use processing, the effects that playing suture, connection, reinforce.Sewing thread matter
The quality of amount not only influences sewing efficiency and processing cost, also influences the stable structure and presentation quality of suture product.Industry is stitched
Line of threading is generally divided into natural fiber sewing thread, synthetic fibers sewing thread and mixing sewing thread three categories by raw material.In sewing, need
Want sewing thread frictional resistance small, it is soft；After it has been gathered, need product secured, sewing thread does not slide.Composite yarn is the one of sewing thread
Kind, the structure feature of composite yarn is by its length/short, and short/short, long/long compositely proportional is determined with tension.
Extension strain that Poisson ratio material, which refers to material, to be generated when being acted on by the tensile load of a direction and perpendicular to
The ratio between contraction strain of draw direction.Under normal circumstances, when most material is stretched, the Poisson ratio measured is all
One positive value, and negative poisson's ratio（Negative Poisson’s Ratio）Phenomenon is then completely on the contrary, when material is in a direction
On be stretched load effect when, expansion can be generated to a certain extent instead on the direction perpendicular to drawing force.It is negative
Poisson's ratio yarn it is simple definition be：When outer force effect is axially stretched, diameter increased yarn instead.Negative poisson's ratio yarn
Design although have existed, but be limited to its structure constitute and composition material, currently, just material object for, there is no negative poisson's ratio

The principle of the present invention is described as follows：
Composite yarn is one kind of sewing thread, and the structure feature of composite yarn is by its length/short, short/short, long/long compositely proportional and tension
It is determined.
The short fibre of chemical fibre：Refer to that the staple fiber in chemical fibre, chemical fibre include terylene, acrylic fibers, polyamide fibre etc., staple fiber
Including cotton, wool type, medium-length etc..
The short fibre of chemical fibre --- rove item：Its manufacturing procedure can also be original either raw material, Blowing carding, drafting, rove
Material, thermal finalization, Blowing carding, drafting, rove, wherein thermal finalization is the process that can be selected.
POY long filaments：Refer to POY（Pre-oriented yarn）Preoriented yarn.
AIRJET TEXTURING YARN：Using compressed air, make the long filament of chemical fibre that air jet texturing occur, tow outer ring is locally risen small
Volume, then make its portion fractures, it forms several ends and is exposed, can preferably be suitable for sewing thread field.AIRJET TEXTURING YARN
It is a kind of processing method, feedstock property is not changed.The present invention uses POY long filaments for raw material, makes AIRJET TEXTURING YARN, makes
When, over feed rate(OFR) is 25% -50%, meanwhile, limit the elongation at breaks of POY long filaments as 30% -60%, the AIRJET TEXTURING YARN being fabricated to
Elongation at break be limited to 75% -300%.
The diameter of rove item is the 75% -125% of air-texturing long filament beam diameter：Optimal selection is rove item, air-texturing
The diameter of endless tow is consistent, and such most convenient is manufactured.Because when processing, with two root unit body feeding speed of thickness
Unanimously, when twisting, two root unit bodies generate identical twist contraction, and the structure of two root unit body loopings arranged side by side is just stablized, just suitable for this
The actual fabrication of composite yarn and large-scale production in invention.
Rove item/endless tow composite yarn in the present invention is rove item by one after drawing-off and one without drawing-off
But there is the composite yarn that the air-texturing endless tow of some tension control is formed in twist triangle zone composite twist, base between two components
It is not shifted in sheet, mutually twisted looping together, forms and is similar to single thread, the yarn of structure liny outside a kind of.Referring to Fig. 1 and figure
2, when in an axial direction by force-extension, rove item is not likely to produce deformation since its resilience is relatively poor, in the work of external force
It is tightened under, forms sandwich layer yarn, and the rove item that air-texturing endless tow can then be stretched squeezes and buckling, forms yarn helix
It is wrapped in outside rove item, forms fasciated yarn.Assuming that the width of single thread（Diameter）For D, before stretching, rove item/endless tow is multiple
The width of yarn is closed as rove item, the sum of the diameter of air-texturing endless tow, as 2D, air-texturing is long after composite yarn is stretched
After tow translates into looping structure, the width of composite yarn becomes 3D, i.e. composite yarn produces drawn expanded.Through the invention
Rove item/endless tow composite yarn obtained has the characteristics that adapt to sew and suture at a high speed secured：On the one hand, in sewing, due to
Cable architecture of sewing is conducive to puncture suture uniformly without filoplume, meanwhile, have high intensity, the rove item of high rigidity feature undertakes sewing
The effect of tension is suitble to high speed sewing processing；On the other hand, the product of suture, stretches under external force, have high flexibility,
The air-texturing endless tow of high resiliency feature will produce winding effect, and sewing thread generates lateral expansion because of stretching, and prevents
The sliding of sewing thread.
Rove item after drawing-off, the air-texturing endless tow for having tension force：Rove item requires drawing-off, it is therefore an objective to thick
Sliver（Thicker yarn）It draws and attenuates；Air-texturing long filament beam request tension force is because not generate stress concentration.
Winding procedure：That is reeling process.This process changes package, increases the Rong Siliang of tow package, improves later process
Productivity.Operation while, tow is checked using yarn cleaning device, remove tow on fault influential on quality and
Impurity, such as slubbing, details, double yarns, soft twist yarn, cotton knot etc..
High-temperature shaping process：Under certain temperature and damp condition, no-station pole canopy heat treatment is carried out to primary yarn, eliminates yarn
Because of the internal stress that twisting generates, stablize the twist of composite yarn, the twist contraction that composite yarn generates is avoided to influence presentation quality.

Item, twist factor are 60-130；The fracture strength of the short fibre of chemical fibre is 5.0 cN/dtex -10.0 cN/dtex, extension at break
Rate is 7% -23%；
The acquisition air-texturing endless tow refers to：Selected POY long filaments are passed sequentially through into precursor stretching, deformation, thermostabilization, are determined
Type, rolling step, to obtain air-texturing endless tow；The elongation at break of the POY long filaments passes through for 30% -60%, POY long filaments
Over feed rate(OFR) when deformation processing is at AIRJET TEXTURING YARN is 25% -50%, and the elongation at break of AIRJET TEXTURING YARN is 75% -300%.
10. a kind of manufacture of rove item/endless tow composite yarn with drawn expanded performance according to claim 7 or 8
Method, it is characterised in that：
Rove item after the drawing-off refers to：When the draft area that rove drawing-in three forms roller, three pairs of rollers are to drawing-in
Rove item carries out drawing-off, draws and attenuates；
