Problems solved by technology

[0007] Segment colored yarn is spun by coaxial double rear rollers, and the two groups of fibers are segmented, equal in amount, and unequal in proportion to combine into yarn. When the two groups of fibers are single-component and alternate with each other, the drafting multiple of the front area of ​​the general

Embodiment

[0027] Such as figure 1 and figure 2 As shown, the method for forming colored yarn by ring spinning section of the present invention, the group A fiber strip T 甲 , the second group of fiber strips T 乙 Feed the back roller 4 through the yarn guide rod 1 and the bell mouth 3 of the split grid 2 respectively, and are respectively clamped by the fixed back roller 41 on the back roller 43 shaft and the looper back roller 42, and then fed into the middle roller shaft 53. The fixed middle roller 51 and the looper middle roller 52 pass through the gauge collector 6 to the front roller 7, and the fiber strands of A and B groups after being drafted and output by the front roller 7 pass through the Y-shaped surface of the negative pressure suction tube 8 Guide grooves, under the action of air guidance, gather together, output through guide rubber roller 9, and are twisted into colored yarns of equal linear density.

[0028] During normal spinning, in the i-th process section, the fee...

Abstract

A ring spun sectional-color yarn preparing method includes: feeding a first group of fiber strips and a second group of fiber strips with yarn density tex of Tst and Tnd into two back rollers and two middle rollers pairwise from a yarn guide rod, a splitting grate and a distance separation bell mouth, controlling rotation speed of the middle rollers by stages through a computer program controller, feeding the fiber strips to the front rollers while keeping the sum of feeding of the first group and the second group of the fiber strips constant, aggregating loosened small fiber strips of the group A and the group B drafted and output from the front rollers under the guide action of air after passing a Y-shaped guide groove on the surface of a negative-pressure suction aggregation pipe, outputting the aggregated fiber strips to a guide rubber roller and twisting the same to be sectional-color yarns with identical yarn density.

Description

technical field [0001] The invention belongs to the field of spinning and forming processing, and relates to a ring-spinning colored yarn and a yarn forming method thereof, and a device suitable for the yarn forming method of the invention. Background technique [0002] Segment colored yarn is a yarn in which the yarn color is intermittently distributed in the longitudinal direction of the yarn. At present, the color combination and yarn structure of segment colored yarn produced by existing production technology are quite different because of their different production and processing methods. [0003] For segment-colored yarn produced by skein or single-yarn segment dyeing, the fibers in each segment of the segment-colored yarn are basically the same color, and the segment-colored yarn is dull in color and prone to heavy regularity. [0004] Segment-colored yarn produced by blending and re-dying of fibers with different coloring properties has few color combinations, and t...
