Description
Technical field
This utility model is related to a kind of asynchronous drawing-off boundling spinning apparatus of four-way.
Background technology
Colour-spun yarns are formed by the short fiber blending of different colours, and it can present nature, gay colours, and tone is soft
With, it is warm, the fabric being made into has dim stereoeffect, thus is received by the market very much.The change of original liquid coloring in recent years
Learn production technology, the staple in bulk of all kinds of natural fibers of fiber (colored fibre such as such as coloured viscose, colored terylene, color acrylic fibre)
Staining technique reaches its maturity, and is that fine Industry Foundation has been established in the development of colour-spun yarns.Through the development of nearly more than ten years, lead in China
The textile fabrics industrial chain being initially formed centered on colour-spun yarns, upstream are related to original liquid coloring chemical fibre and dye natural fibre
Dimension, downstream are related to clothing, home textile textile.Colour-spun yarns have become important textile production side in wool spinning, cotton spinning field
Formula, production scale have reached 10,000,000 ingots, will become textile production mode important from now on.
The production of colour-spun yarns is typically taken and grabs cotton colour mixture, drafting colour mixture, grabs cotton and many component spinnings of drafting dual-purpose colour mixture, spun yarn
The techniques such as yarn colour mixture, doubling double twisting colour mixture, the color textile product appearance style of formation can be divided into the uniform colour-spun yarns of colour mixture, colour mixture not
Uniform colour-spun yarns, the number of colours of colour-spun yarns can be divided into double-colored colour-spun yarns, polychrome colour-spun yarns, and colour-spun yarns mixed proportion can be divided into low
Ratio colour-spun yarns (color fibre≤10%), at high proportion middle ratio colour-spun yarns (10%≤color fibre≤40%), colour-spun yarns (color fibre
>=40%).As, in existing colour-spun yarns production model, the mixing of different color fiber and spinning forming be not in same one procedure
In carry out, be the mixing of heterochromatic fiber formerly, after yarn is formed in, thus cause the heterochromatic fiber mixed proportion in the yarn can not
Arbitrarily regulate and control, cannot also be precisely controlled and realize color.Therefore in actual production, the color of colour-spun yarns arbitrarily cannot regulate and control, color
Distribution also arbitrarily cannot regulate and control, it is this in theoretical and technical short-leg, cause colour-spun yarns color and the design of flower pattern to lack
Means, colour-spun yarns new product development are greatly limited.
For the problems referred to above, patent application of the prior art：" blending is realized based on three rove coupling draw twisting system
And the device and method (CN201310369692.2) of colour mixture ", " three-primary colours rove mixture production illusion-colour yarn method and the method
The illusion-colour yarn (CN201410176434.7) of preparation ", " the draw twisting device that three rove independence drawing-offs are synchronously twisted
" (CN201320516412.1) two patent of invention patents and a utility model patent such as, this three patent applications are by electricity
Brain programme-control and servo-drive, can on-line continuous change the mix ratio of heterochromatic fiber so as to form random point along length of yarn
Cloth.
The color (form and aspect, lightness, saturation) of colour-spun yarns is that the fiber of different colours is formed Jing after spatial juxtaposition mixing
Color, it depend on colour-spun yarns outer layer distribution each color fibre shared by area ratio, by the blending ratio of color fibre, color fibre
Distribution (yarn texture) and its twist in the yarn is determined.Traditional colour spinning technique can not arbitrarily regulate and control colour mixture ratio, therefore not
Colour-spun yarns color blending effect can arbitrarily be regulated and controled.And patent application " realizes blending and color mixing based on three rove coupling draw twisting system
Device and method (CN201310369692.2) ", " three-primary colours rove mixture production illusion-colour yarn method and the method prepare
Illusion-colour yarn (CN201410176434.7) ", " the draw twisting device that three rove independence drawing-offs are synchronously twisted
(CN201320516412.1), in ", the blending ratio of colour-spun yarns arbitrarily and is immediately regulated and controled by asynchronous drawing-off, and then realizes colour-spun yarns
Any change of mixed color and immediately change.As two rove are distinguished Jing after different draft ratio drawing-offs again in front roller
Jaw converges and twists, and when the thickness of two root hair bars occurs change at random and when differing greatly, the twisting point which crosses can be with
The change of draft ratio and move about, it is impossible to form stable twist triangle zone.Thus, on the one hand cause the random of color fibre distribution
Property, on the other hand cause yarn actual twist suddenly big or suddenly small and deviation theory value.Due to the randomness that color fibre and the twist change,
Cause color fibre in the uncontrollability of the yarn outer layer regularity of distribution.It is known that in colour-spun yarns fiber different colours hybrid guided mode
Formula meets the spatial juxtaposition mixing of color, and color blending effect should be depending on the area ratio and sth. made by twisting for floating over each primary colours fiber in yarn top layer
The distribution of degree.Multichannel number colour-spun yarns produce random movement due to twisting point, and twist triangle zone form is unstable, thus cannot
The regularity of distribution of the control color fibre on colour-spun yarns top layer, therefore the accurate of the control accurate and mixing aberration of mixed color cannot be realized
Regulation and control, cause actual color blending effect to there is larger difference with theoretical color blending effect.For example, CN201310369692.2,
In CN201410176434.7, CN201320516412.1, Jing after drawing-off, the yarn of two rove is formed at front roller nip
Twist triangle zone form can change because of the change of two roving-drafting ratios, as the doubling twisting region of two root hair bars is sent out
Life is fluctuated and causes yarn texture to change, and causes the area ratio of each color fibre distribution in fiber dyed yarn surface violent ripple occur
Setting value is moved and deviates, so as to affect the uniformity and stability of color blending effect (including form and aspect, lightness, saturation).
