Abstract
The invention relates to a method for manufacturing a double-color-changing short fiber/short fiber wrapping yarn, which is characterized in that a spinning former with arc left and right sides is additionally arranged at a front roller strip-discharging position of a ring spinning frame, and the angle of the former can be adjusted by left tilting or right tilting. During spinning, 2 kinds of short fiber roving in different colors are fed parallelly for drafting, and A, B two-color short fiber strands are output along two sides of the former. When the former is in the middle position, the two-color short fiber generates two-color twist effect; if the former inclines rightwards, spinning the B color short fiber to wrap the A color short fiber wrapping yarn; if the former inclines left, the yarn is spun into the yarn with the color A short fiber wrapped by the color B short fiber wrapped yarn. According to the process setting and the yarn effect requirement, the position of the spinning former and the staying time of the position are adjustable, so that the double-staple fiber wrapped yarn along the length direction of the yarn can form a double-color change effect with a certain rule or irregularity, an equal distance or unequal distance.
Description
Technical Field
The invention relates to a method for manufacturing a bi-color-changing short fiber/short fiber wrapping yarn.
Background
In the prior art, most of the double-color-changing yarns are spun yarns produced on a modified ring spinning frame, and the modification of the spinning frame has the disadvantages of large workload, complex mechanism and high cost. Or the color-changing fancy yarns produced by the hollow spindle fancy spinning machine.
Disclosure of Invention
The invention aims to provide a method for manufacturing a double-color-changing short fiber/short fiber wrapping yarn, which is characterized in that a peach-shaped spinning former capable of adjusting the angle is additionally arranged at the position of a front roller strip outlet position of a traditional spinning frame, which is positioned between two fiber strips, the spinning former is driven by a motor, and the angle can be adjusted by inclining to the left and inclining to the right under the control of a computer program. The raw material form of the wrapping yarn is short fiber wrapped by short fiber, 2 different colors are selected for core wire and outer wrapping fiber, and the position of the continuous spinning former is changed during spinning to generate double-color alternate wrapping effect.
The technical scheme of the invention is as follows: a spinning former is arranged at the position where a front roller discharges strips, is positioned in the middle of two fiber strands, and can be driven by a motor to tilt left and right to adjust the angle. The A color short fiber rough yarn and the B color short fiber rough yarn are fed by a rear roller and are drafted by a drafting mechanism to output color short fiber strands. When the spinning former is at different angles, the two colored fiber strands are output along different arc surfaces of the spinning former, and 3 yarn color changing effects of AB color cross twist, B color short fiber strand wrapping A color short fiber strand, A color short fiber strand wrapping B color short fiber strand and the like are respectively formed through twisting of a ring spindle.
Compared with the prior art, the invention has the following advantages: the equipment is simple to transform; obtaining wrapping yarn with two colors changing alternately in appearance and having the effect of pattern yarn; a new yarn structure is obtained.

Detailed Description
Referring to attached drawings 1, 2 and 3, the method for manufacturing the bicolor staple fiber wrap yarn is mainly disclosed. The front roller is arranged in the middle of two strands and is provided with a peach-shaped spinning former with left and right sides in arc surfaces, and the spinning former is driven by a motor and can be controlled by a computer program to adjust angles to incline left and right. The A color short fiber roving 1 and the B color short fiber roving 2 are fed by a rear roller 3, pass through a middle roller 4, and output an A color short fiber strand 6 and a B color short fiber strand 7 by a front roller 5. FIG. 1 shows that when the spinning former 8 is in the middle position, the B-color short fiber strands 7 are output along the left arc-shaped surface 9 of the spinning former 8, the A-color short fiber strands 6 are output along the right arc-shaped surface 10 of the spinning former 8, and are converged with the B-color short fiber strands 7 at the wrapping point 11, and the A-color short fiber strands 6 and the B-color short fiber strands 7 generate the cross twisting effect through the ring twisting action; in the attached figure 2, the spinning former is inclined at a certain angle at the right, the A-color short fiber strands 6 are output along the left arc-shaped surface 9 of the spinning former 8 during output, the B-color short fiber strands 7 are output along the right arc-shaped surface 10 of the spinning former 8, the B-color short fiber strands 7 wrap the A-color short fiber strands 6 after twisting, and the B-color short fibers are spun to wrap the A-color short fiber wrapping yarns. In the attached figure 3, the spinning former inclines to the left for a certain angle, when the spinning former outputs, the A color short fiber strands 6 are output along the left arc-shaped surface 9 of the spinning former 8, the B color short fiber strands 7 are output along the right arc-shaped surface 10 of the spinning former 8, after twisting, the A color short fiber strands 6 wrap the B color short fiber strands 7, and the A short fibers are spun to wrap the B short fiber wrapping yarns. During spinning, the spinning former 8 can be randomly changed to the positions shown in the attached figures 1, 2 and 3 according to the process setting, and the color change effect is realized by wrapping the yarns 12.
The speed of the front roller 5 is controlled to determine the spinning and twisting speed.
