Description
Technical field
The present invention relates to ring spinning new technical field, specifically a kind of four rove feeding super draft color section ring color yarn spinning method.
Background technology
The RING SPINNING being realized twisting by spindle rotation is spinning method the most traditional, also be on current market consumption at most, the most general spinning method, technology is very ripe, although there is the Advanced Spinning Technologies that a lot of production efficiency is high, technological process is short at present, as Revolving cup spinning, Air-Jet Spinning etc., especially Air-Jet Spinning, employing High Rotation Speed air-flow makes fibre bundle false twisting looping resultant yarn and revolutionizes the twisting mechanism of RING SPINNING, but these spinning methods still cannot replace RING SPINNING on adaptability to raw materials and yarn oeverall quality.Therefore, current RING SPINNING remains the topmost spun yarn mode of production.The most popular problem of current textile industry by improving to realize the production of high-quality spun yarn to traditional ring spinning technology.Especially the ring throstle that current domestic main flow uses all adopts three roller two district weighing draft, and drafting multiple is restricted, and spinning efficiency is lower.On the other hand, along with continuing to increase of market competition is strengthened gradually with China textile industry structural adjustment investment, be improve added value of product and the market competitiveness, yarn variety is gradually to highly-branched, differentiation future development.For this, the present invention adopts on a kind of super draft fine spining machine comprising four roller four apron three district weighing draft, adopts four rove feedings to produce a kind of color section ring color yarn, and provides corresponding spinning method.
Summary of the invention
The object of the present invention is to provide the spinning method of a kind of four rove feeding super draft color section ring color yarn, to overcome prior art Problems existing.
The present invention for achieving the above object, adopts following technical scheme:
A kind of color section ring color yarn spinning method, it is characterized in that: adopt the rove of four at least one colors to feed the super draft fine spining machine of four roller four apron three district weighing draft at spinning process simultaneously, described four rove wherein two feed from rear roller through double horn mouth, a rove is through yarn guiding trough therefrom rear roller feeding, and a rove is through yarn guiding trough therefrom front roller feeding.
By above-mentioned four rove feeding schemes, the multicomponent section coloured yarn line that can realize being up to four kinds of different colors is produced, realize the production of the section coloured yarn line of different-style, improve yarn added value, adopt four roller four apron three district weighing draft to realize super draft simultaneously, and the rear roller in four rollers, middle rear roller and middle front roller adopt independent Serve Motor Control respectively, realize any adjustment of drafting multiple in the drawing-off of 3rd district, thus the color ring effect of the section realizing various different-style, improve spin ability and the yarn quality of section coloured yarn line.
For realizing the spinning of multicomponent multicolour section coloured yarn line, it is characterized in that, comprise the steps:
(1) distribute cotton:
