Fig. 1 is a kind of side of the preparation method of looping structure elastic ring circle composite yarn shown according to an exemplary embodiment
Method schematic diagram, as shown in Figure 1, the preparation method of the looping structure elastic ring circle composite yarn includes:
Step 100: being continuously applied the drafting force of default drafting multiple to stretch yarn, the stretch yarn is made to be in drawing-off shape
State.
In a preferred embodiment, the implementation steps of step 100 may include: by stretch yarn through feeding roller friction
Transmission effect bypasses cord roller after the unwinding of the first heart yarn cylinder, passes through chain drive system between the feeding roller and the cord roller
Transmission, the linear resonance surface velocity of the cord roller are greater than the linear resonance surface velocity of the feeding roller, thus to the cord roller with it is described
The stretch yarn between feeding roller applies the drafting force of default drafting multiple, and the stretch yarn is made to be in drawing-off state.
In one possible implementation, the stretch yarn includes transparent spandex monofilament, the line of the stretch yarn
Density is 70D ~ 250D, and the drafting multiple of the stretch yarn is 2.5 ~ 5 times, and the looping twist of the outer fasciated yarn is 400-
600 twists/m.
It should be noted that applying default drawing-off times to the stretch yarn between cord roller and feeding roller in the present invention
Several drafting forces can be adjusted by the cooperation to cord roller and feeding roller linear resonance surface velocity and be realized, identical in other parameters
Under conditions of, the drafting multiple of stretch yarn is bigger, and looping structure elastic ring circle composite yarn is finally prepared and is formed by yarn
Circle size is bigger, accordingly thicker in the yarn ring layer of fabric surface formation.
Step 200: by non-elastic yarn and the stretch yarn under the drawing-off state and closing, form elasticity/non-ballistic
Property twin-core yarn.
Non-elastic yarn can be filament yarns or the spun yarns such as polylactic acid yarn, purified cotton yarns, Acrylic Fiber.
In a preferred embodiment, step 200 may include:
(1) at least one non-elastic yarn is unwound and is passed through twizzle from the second heart yarn cylinder by the way of passiveness feeding, pass through
After spring tensioner applies tension, from the central tube of lower end feeding hollow ingot.
(2) stretch yarn under drawing-off state is fed into the hollow ingot from lower end around after cord roller
Central tube is formed so that the non-elastic yarn in the central tube and is closed with the stretch yarn under drawing-off state
Elasticity/non-resilient twin-core yarn.
(3) it after the elasticity/non-resilient twin-core yarn being passed through the central tube, is sent into merge under the guidance for drawing yarn roller and lead
Yarn hook.
It should be noted that non-elastic yarn applies certain during unwinding feeding by spring tensioner
Power can keep non-elastic yarn to have certain tensioning degree, and the non-elastic yarn and stretch yarn for avoiding relaxed state are rear
By the effect of outer fasciated yarn balloon tension caused to move during continuous outer fasciated yarn looping it is unstable, influence looping it is normal into
The capable formation with looping structure.Wherein, the adjustment of non-stretchable heart yarn tension is real by the spring pressure of spring tensioner intermediate plate
It is existing.
Step 300: outer fasciated yarn being wrapped in the elasticity/non-resilient twin-core yarn surface in spiral form, forms looping knot
Structure complex yarn.
In a preferred embodiment, step 300 may include:
(1) power supply for starting the hollow ingot, so that the hollow ingot high-speed rotation.
(2) the outer fasciated yarn being wound on the aluminium ingot pipe is unwound with the rotation of the hollow ingot, is led in the congregation
It merges at yarn hook with the elasticity/non-resilient twin-core yarn, and is wrapped in the elasticity/non-resilient twin-core yarn surface in spiral form,
Form looping structure composite yarn.
(3) after the looping structure composite yarn being drawn the extraction of yarn roller, lever jack is bypassed, through leading on traverse guide
The guidance of yarn porcelain eye, is wound to by the bobbin of take-up roll frictional drive, wherein the linear resonance surface velocity of the take-up roll draws yarn with described
The ratio of roller surface linear velocity is 0.5 ~ 0.7.
When looping structure composite yarn, which is drawn yarn roller, draws, stretch yarn therein is in the tensioning of larger drafting multiple
Drawing-off state, if drawing yarn speed and being directly wound up on bobbin looping structure composite yarn to be more than or equal to, stretch yarn
The elastic force of line can lose with the time effect of storage, the transport of looping structure composite yarn, and therefore, the present invention passes through
The linear resonance surface velocity of take-up roll is adjusted to control the winding drafting multiple of stretch yarn and (the linear resonance surface velocity of take-up roll and draw yarn
The ratio of roller surface linear velocity) it is 0.5 ~ 0.7, so that the looping structure composite yarn of winding on bobbins will not be because winding than excessive
Or it is too small and cause to shape slack and undisciplined and loss resilience.
Step 400: the drafting force decorporated to stretch yarn described in the looping structure composite yarn, so that the looping
The stretch yarn elastical retraction in structure composite yarn is non-described in the looping structure composite yarn to undrawn state
Stretch yarn acts on the bending compression in generation yarn axis direction because of the elastical retraction of the stretch yarn, and then in the looping knot
Looping structure elastic ring circle composite yarn is prepared in convex shaped resultant yarn circle between the helical of structure complex yarn China and foreign countries fasciated yarn.
After looping structure composite yarn winding forms cylinder yarn to bobbin, due to the stretch yarn in looping structure composite yarn
It is still in drawing-off state, the yarn circle that complex yarn line body generates is smaller and few, therefore in prolonged storage, transportational process
Deformation, winding or phenomenon of rupture are less likely to occur.
It, can be by looping structure composite yarn when user needs to carry out the weaving of fabric using looping structure composite yarn
It is normally unwound from bobbin without drawing-off, at this point, elastic force elasticity bounces back to undrawn state in looping structure composite yarn, packet
In entanglement structure complex yarn non-elastic yarn because stretch yarn elastical retraction effect occur yarn axis direction on bending compression, into
And the convex shaped resultant yarn circle between the helical of looping structure composite yarn China and foreign countries fasciated yarn, and yarn circle with stretch yarn elasticity gradually
Restore and become larger, ultimately forms looping structure elastic ring circle composite yarn.
In order to illustrate the forming process of looping structure elastic ring circle composite yarn meduim yarn circle provided by the invention, show such as Fig. 2
Shown in looping structure elastic ring circle composite yarn meduim yarn circle formation schematic diagram, in Fig. 2, A be yarn circle formed first stage,
In the A stage, looping structure elastic ring circle composite yarn is for tensioning state；B is the second stage that yarn circle is formed, in B-stage,
Stretch yarn in looping structure elastic ring circle composite yarn bounces back, and yarn circle gradually generates；C is the third rank that yarn circle is formed
Section, in C-stage, the stretch yarn in looping structure elastic ring circle composite yarn continues to bounce back, and yarn circle continues to increase；D is yarn circle
The fourth stage of formation, in the d stage, the stretch yarn retraction in looping structure elastic ring circle composite yarn terminate, and can be observed
Obvious and rounding Loop Yarns.
It should be noted that the generation type of existing Loop Yarns meduim yarn circle is mainly staple fiber yarn looping, this mode
Whole tangled by loose staggered staple fiber yarn of obtained yarn circle is constituted, and yarn coil structures are destroyed vulnerable to external force, using existing circle
After loop yarn carries out the weaving of subsequent fabric, fabric itself is also easy to influence the fabric taking of fabric because yarn coil structures destroy
Can, further result in the chain destruction of this body structure of fabric；And looping structure elastic ring circle composite yarn meduim yarn provided by the invention
The generation type of circle is elastic force looping, and the yarn circle that this mode obtains integrally is made of complete yarn, therefore yarn coil structures are steady
Surely it is not easy to be destroyed, yarn circle effect can be kept for a long time in long-term storage use and subsequent product preparation process, by this
After looping structure elastic ring circle composite yarn carries out the weaving of subsequent fabric, the fabric wearability of fabric, especially tactile is comfortable
It is more outstanding that property compares existing Loop Yarns fabric.
Further, Loop Yarns are the yarn that a large amount of yarn circles are distributed with along its length, the Loop Yarns being prepared by it
In use, each yarn circle of product surface is highly susceptible to foreign object and pulls product, such as by sharp tables and chairs corner angle hook
Jewelry hook hang, dressed by user etc..Due to the limitation of looping mode, existing Loop Yarns do not have any elasticity still in the market
Feature, but also existing Loop Yarns product, during routine use, yarn circle is more susceptible to external force and pulls and form the plane of disruption, in shadow
Product appearance is rung simultaneously, but also fracture yarn detaches from Loop Yarns product and Loop Yarns product is caused integrally to be scrapped；And this
The looping structure elastic ring circle composite yarn that invention provides uses exclusive elastic force looping mode, so that looping structure elastic ring circle is multiple
It closes yarn itself and has certain elastic performance, using Loop Yarns product made of the compound weaving yarns of looping structure elastic ring circle,
When being hooked by foreign object, the elastomeric yarn in looping structure elastic ring circle composite yarn structure can generate each yarn circle in its surface
Buffering effect, to ensure that each yarn coil structures are not destroyed.
In a preferred embodiment, the screw pitch of each helical of looping structure composite yarn China and foreign countries fasciated yarn is pressed
Default rule variation.
The screw pitch of each helical of looping structure composite yarn China and foreign countries fasciated yarn can pass through the looping twist during looping
Size adjustment, wherein the looping twist is the circle number of the outer fasciated yarn of winding on unit length heart yarn, numerically equal to hollow ingot revolving speed
(r/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).When the looping twist
When smaller, the circle number that outer fasciated yarn is wound on unit length heart yarn is few, and outer fasciated yarn makees the constraint of elasticity/non-resilient twin-core yarn
With weak, non-elastic yarn is easy to multiple from protrusion, looping, unit length between biggish outer fasciated yarn screw pitch when stretch yarn bounces back
It is small that conjunction yarn looping quantity encloses shape more；Conversely, winding the circle number of outer fasciated yarn on unit length heart yarn when the looping twist is larger
More, the screw pitch of looping helical is small, and outer fasciated yarn acts on by force elasticity/non-resilient twin-core yarn constraint, and non-elastic yarn is in stretch yarn
Difficult from protrusion, looping between lesser outer fasciated yarn screw pitch when line bounces back, unit length composite yarn looping quantity is few and to enclose shape big.
In the present invention, the looping twist can be realized by adjusting hollow ingot ingot speed, in feeding roller and draw the constant situation of yarn roller speed
Under, hollow ingot revolving speed is bigger, and the looping twist is bigger.In a kind of possible embodiment, the looping twist of this technology is 400-
600T/m。
The present invention can be advised by controlling the screw pitch of each helical of looping structure composite yarn China and foreign countries fasciated yarn as default
Rule variation, so that the distribution of finally formed looping structure elastic ring circle composite yarn meduim yarn circle is controllable.
For example, during looping feeding roller and draw yarn roller speed it is constant in the case where, adjustment hollow ingot ingot speed according to
The periodical rotation speed change of " 1 times of the first 3 times of unit time preset rotation speed, the second unit time preset rotation speed ", so that looping knot
Structure complex yarn China and foreign countries' fasciated yarn reduces 3 times every the unit time twist, outsourcing in the looping structure composite yarn line body of formation
The screw pitch for twining yarn increases every unit period, and yarn circle is more readily formed between these biggish screw pitch.
In a preferred embodiment, the quantity of the non-elastic yarn is at least two, each non-elastic yarn
Color is different；The color of the non-elastic yarn is different from the color of the outer fasciated yarn.
When the quantity of non-elastic yarn that the present invention uses be at least two, and the color difference of each non-elastic yarn
When, looping structure elastic ring circle composite yarn surface, which is made, can form each yarn circle to vary in color, this looping structure elastic ring
It is in the color blending effect of multiple color yarn circle on the surface layer of fabric, and since yarn circle quantity increases after enclosing composite yarn woven into fabric, and
Increase the yarn ring layer density of fabric, so that thickness and elasticity increase.When using more homochromy non-elastic yarns, increasing is also had
Add the yarn ring layer density of fabric, to increase the effect of fabric yarn ring layer thickness and elasticity, the yarn circle of unlike material forms fabric
Surface layer can also mutually make up in the wearability of fabric, optimize；When non-elastic yarn and outer fasciated yarn are heterochromatic, then it is knitted
Object forms similar fur structure, i.e. batt is formed by yarn circle, and color is yarn circle color；Cortex is formed by yarn body, and color is non-ballistic
The colour mixture of power yarn and outer fasciated yarn, and, when yarn circle is relatively sparse, the color of fabric body also can be able to portion through yarn ring layer
Divide and present, increases the level of fabric apparent colour.
It should be noted that the feeding of more non-elastic yarns can be real by increasing the feeding unit of non-elastic yarn
It is existing.
In conclusion a kind of preparation method of looping structure elastic ring circle composite yarn provided by the invention, by that will be in
