Specific embodiment
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing.
Fig. 1 is that a kind of method of the preparation method of looping structure elastic force section coloured yarn shown according to an exemplary embodiment is shown
It is intended to, as shown in Figure 1, the preparation method of the looping structure elastic force section coloured yarn includes:
Step (1): the drafting force that drafting multiple is 1.5-3 times is applied to elastic force heart yarn, the elastic force heart yarn is made to be in drawing-off shape
State, the line density of the elastic force heart yarn are 70D-150D.
In a preferred embodiment, the elastic force heart yarn is one in transparent spandex monofilament or thermoplastic polyurethane
Kind.
It should be noted that the drafting multiple of elastic force heart yarn is in complex yarn spinning, resultant yarn draws yarn roller and draws yarn speed
(i.e. linear resonance surface velocity, unit: m/min) and elastic force core filaments feeding roller feeding speed (i.e. linear resonance surface velocity, unit: m/min)
Ratio, the feeding speed by adjusting elastic force heart yarn feeding roller are adjusted.The drafting multiple of elastic force heart yarn determines final be made
The elastic range and section coloured yarn appearance of looping structure elastic force section coloured yarn, than such as whether ripple, twist together and ripple, kink number
Amount.When the drafting multiple of elastic force heart yarn is big, the elasticity that looping structure elastic force section coloured yarn is made is big, but resultant yarn ripples big, torsion
Tie it is more, ripple caused by this elasticity and kink after woven into fabric because the intertexture of yarn, fluctuating due to are stretched, but such as
Fruit ripples, and big, kink is too many too big, stretches and is not thorough after weaving, then will affect appearance of fabrics quality.Comprehensively consider resultant yarn bullet
Property and appearance, the present invention by lot of experiments determine elastic force heart yarn drafting multiple be 1.5-3 times.
Step (2): will be after at least two heterochromatic colored heart yarns unwind from heart yarn cylinder respectively in a manner of passive feeding, through leading
Yarn hook and close form compound heart yarn.
In a preferred embodiment, the heterochromatic colored heart yarn is polyamide fibre 6, polyamide fibre 66 or poly terephthalic acid 1.3
One of propylene glycol ester PTT.
It should be noted that tension of the heterochromatic colour heart yarn in spinning process is bigger, elongation is also bigger, when elastic force core
When yarn bounces back, the elastical retraction of itself is also big, thus can absorb the more amount of recovery of elastic force heart yarn, and elastic force section coloured yarn is not easy wave inception
Line or kink.But if the tension of heterochromatic colour heart yarn is too big, it will lead to delivery roller and draw yarn difficulty, yarn is clamped in delivery roller
It skids under mouthful.The principle that the present invention controls heterochromatic colored core yarn tension is: under the premise of guaranteeing that delivery roller smoothly draws yarn,
Tension adjustment as bigger than normal as possible, to guarantee that heterochromatic colored heart yarn extends as far as possible in spinning process.
Step (3): by the compound heart yarn after spring tensioner applies tension, with the institute under drawing-off state
It states elastic force heart yarn and amounts to feeding hollow ingot central tube, form composite elastic heart yarn.
Step (4): the composite elastic heart yarn is existed with the outer fasciated yarn being sheathed on the hollow ingot outside aluminium ingot pipe
After merging at congregation twizzle, starts the hollow ingot and make the hollow ingot that the aluminium ingot pipe be driven to turn round jointly, and with
By the outer fasciated yarn, helically threadiness is forward wrapped in composite elastic heart yarn surface to the looping twist of 400-600T/m, makes
The outer fasciated yarn is obtained to the tangential twisting action of application at each looping point in composite elastic heart yarn surface.
The circle number of outer fasciated yarn, numerically equal to hollow ingot revolving speed (r/ are wound on the looping twist, that is, unit length heart yarn
Min) draw yarn roller with resultant yarn and draw the ratio between yarn speed (linear resonance surface velocity m/min), unit is twist/m (T/m).
In a preferred embodiment, the outer fasciated yarn is transparent filament yarn, and the diameter of the outer fasciated yarn is
0.06-0.09mm, the outer fasciated yarn are one of high-elastic blended fabric of silk and polyester, polyamide fibre, ptt fiber.
Step (5): the composite elastic heart yarn generates torsion turn under the tangential twisting action, and in torsion turn
False twist effect under formed section color effect, looping structure elastic force section coloured yarn is prepared, the looping structure elastic force section coloured yarn exists
It is formed under the collective effect of the elastic force heart yarn drafting force, the composite core yarn tension and the outer looping yarn tension irregular
Section color effect.
It should be noted that elastic force heart yarn is applied with certain drawing-off times during being spinned due to looping structure elastic force section coloured yarn
Number, after tensile stress removal, yarn can bounce back under the elastic reaction of elastic force heart yarn.At this point, if generating section color effect
It is 0 that heterochromatic colour heart yarn can bounce back to elongation with the retraction of elastic force heart yarn first, and then with the continuation of elastic force heart yarn
It bounces back and fluffy generation local buckling, then proceedes to the amount of recovery for absorbing elastic force heart yarn, and the control of elastic force heart yarn drafting multiple exists
In lesser range, although looping structure elastic force section coloured yarn can ripple after spinning retraction, or even part kink, but still can reservation paragraph
Color feature, to obtain the section coloured yarn with preferably elasticity.
In addition, the retraction of elastic force heart yarn also causes outer fasciated yarn looping spiral string pitch to reduce, diameter be increased, and be reduced
Constraint to heterochromatic colored heart yarn is conducive to the retraction of heterochromatic colored heart yarn.
It needs to illustrate on the other hand, if generating the heterochromatic colored heart yarn poor flexibility of section color effect, and elastic force heart yarn is led
It is larger to stretch multiple, then looping structure elastic force section coloured yarn heterochromatic colour heart yarn after retraction forms yarn circle, leads to looping structure elastic force
The section coloured silk character modules of section coloured yarn are gelatinized, are not significant, and in order to avoid generating yarn circle phenomenon, the application controls the drawing-off times of elastic force heart yarn
For number at 1.5-3 times, the looping twist selects the filament yarn that elasticity is good, elasticity modulus is low, bending modulus is low to make in 400-600T/m
For heterochromatic colored heart yarn, so that the resultant yarn being prepared has good segments color effect and elasticity simultaneously, it will not be because excessively returning
Contracting generates yarn circle.
In order to preferably make looping structure elastic force section coloured yarn resultant yarn have irregular section of color effect, in a kind of possible reality
It applies in mode, the present invention can by the outer fasciated yarn, helically threadiness be forward wrapped in the composite elastic in step (4)
During heart yarn surface, the surface section of looping structure elastic force section coloured yarn can also be adjusted in real time by following at least one mode
Color effect:
(A) change the feeding speed of the elastic force heart yarn feeding roller, according to preset time rule so as to adjust to the elastic force core
The drafting force of yarn changes within the scope of drafting multiple.
For example, the initial feeding speed of elastic force heart yarn feeding roller is X, the yarn speed of initially drawing that resultant yarn draws yarn roller is 1.5X,
It keeps resultant yarn to draw yarn roller and draws that yarn speed is constant, be at the uniform velocity reduced to the feeding speed of elastic force heart yarn feeding roller by X in 2min
0.5X。
(B) change the feeding speed for drawing yarn roller according to preset time rule, so as to adjust the looping twist in twist number range
It changes.
For example, the initial speed of hollow ingot is 600Y, the yarn speed of initially drawing that resultant yarn draws yarn roller is Y, and hollow ingot is kept to turn
Speed is constant, and the yarn speed of drawing that resultant yarn draws yarn roller is at the uniform velocity increased to 1.5Y from Y in 2min.
In a preferred embodiment, after step (5), the method also includes:
The looping structure elastic force section coloured yarn is drawn yarn roller to draw, bypasses lever jack, the guide porcelain on traverse guide
Eye is wound on the bobbin for being wound roller frictional drive, and winding shaping, the looping are completed under the control of coiling and forming device
The winding drafting multiple of structure elastic force section coloured yarn is 0.6-0.85.
It should be noted that for looping structure elastic force section coloured yarn, it is therein when being drawn the extraction of yarn roller due to resultant yarn
Elastic force heart yarn is in the state of tensioning, if drawing yarn speed and being directly wound up on spool resultant yarn to be more than or equal to, looping structure
The elastic force of elastic force section coloured yarn can lose with coil storage, the time effect transported, therefore the looping structure elastic force
The winding drawing-off of section coloured yarn should be less than 1, and the method for adjustment that the present invention uses controls winding drawing-off for the speed for changing take-up roll
Control range is 0.6-0.85, and too small then cylinder yarn winding shaping is slack and undisciplined, then will increase very much the bullet of looping structure elastic force section coloured yarn greatly
Property loss.
In conclusion a kind of looping structure elastic force section coloured yarn provided by the invention and preparation method thereof, by will be after drawing-off
Elastic force heart yarn and the processing of at least two tensionization heterochromatic colored heart yarn and after closing, using forward hollow ingot wrapping technique looping
Outer fasciated yarn obtains looping structure elastic force section coloured yarn, in preparation flow to elastic force heart yarn drafting multiple, the outer fasciated yarn looping twist,
The parameter strict control of heterochromatic colored core yarn tension, so that looping structure elastic force section coloured yarn elastic force heart yarn drafting force is made, answers
It closes and forms three-dimensional section color effect under the collective effect of heart yarn tension and outer looping yarn tension without looping phenomenon occurs, and
Section color effect stabilization under the action of elastic force heart yarn can be restored.
The looping structure elastic force section coloured yarn and preparation method thereof that embodiment provides in order to better illustrate the present invention, shows one
The schematic diagram of the preparation facilities of kind looping structure elastic force section coloured yarn, as shown in Figure 2:

Pass through programmable controller Collaborative Control, liquid crystal display input setting technological parameter.
In the above process, outer looping yarn tension is false in the heart yarn that the tangential twisting action of composite elastic heart yarn of cylindrical body generates
Effect is twisted, composite elastic heart yarn is made to generate torsion turn, the multicore yarn visible surface being made of heterochromatic colored heart yarn and elastic force heart yarn
Section color effect is presented.The heart yarn section color effect that this twisting generates is retained through the winding of outer fasciated yarn, so that resultant yarn be made to present
Section color effect.Heart yarn tension is unstable, fluctuation is unstable with outer looping yarn tension, and turn added by heart yarn is made to show certain journey
The irregularities of degree.Meanwhile and the elastic force heart yarn being combined and two heterochromatic colored heart yarns in hollow ingot bottom end and hollow ingot
In central tube friction, false twisting effect it is unstable, also to heart yarn twisting turn be distributed to form certain interference, exacerbate the heart yarn twist
Irregularities, assign section color segment distribution erratic behavior.
