[0069] Example 1

[0070] This embodiment discloses a segment color plied yarn spinning frame, which includes a three-roller spinning frame body, such as Figure 1 and Figure 2 As shown, along the processing direction of the yarn, the three-roller spinning frame body includes a roving frame 3, a roving guide rod 4, a rear roller 12, a rear leather roller 15 matched with the rear roller 12, a middle roller 13, a middle leather roller 16 matched with the middle roller 13, a front roller 14, a front leather roller 17 matched with the front roller 14, a yarn guide plate 22, and a yarn guide hook 23; the middle roller 13 and the front roller 14 are driven and rotated by the transmission mechanism of the three-roller spinning frame body;

[0071] The segment color strand spinning machine further comprises a servo motor M, which is transmission-connected to the rear roller 12 to make the rear roller 12 rotate intermittently;

[0072] like Figure 2 As shown, the segment color ply yarn spinning machine also includes a double-groove yarn guide wheel 18. Along the processing direction of the segment color ply yarn spinning machine, the double-groove yarn guide wheel 18 is located upstream of the front leather roller 17, close to the front leather roller 17 and located above the side of the front leather roller 17; the double grooves of the double-groove yarn guide wheel 18 are arranged in parallel on the circumferential surface of the yarn guide wheel.

[0073] like Figure 1 As shown, the segment color strand spinning frame further comprises a yarn hanging rod 1, and the yarn hanging rod 1 is located upstream of the double groove yarn guide wheel 18. The yarn hanging rod 1 is used to hang yarn a and yarn b.

[0074] like Figure 1 As shown, the segment color ply yarn spinning machine also includes a yarn guide assembly for guiding the yarn a and the yarn b to the double groove yarn guide wheel 18 respectively. The yarn guide assembly includes a yarn guide rod and / or a yarn guide hook. More preferably, the yarn guide hook is arranged between the yarn hanging rod 1 and the yarn guide rod; or the yarn guide hook is arranged between the yarn guide rod and the double groove yarn guide wheel 18. The yarn guide assembly enables the yarn a and the yarn b to be smoothly fed into the double groove yarn guide wheel 18, and smoothly enter the front roller 14 and the front leather roller 17. In the case as Figure 1 In the specific embodiment shown, the yarn guide rod includes two 2 and 5, and yarn guide hooks 6 and 7 are provided between the yarn hanging rod 1 and the yarn guide rod 2, which are respectively used to guide yarn a and yarn b; yarn guide hooks 8 and 9 are provided between the yarn guide rod 5 and the double-groove yarn guide wheel 18, which are respectively used to guide yarn a and yarn b into the two grooves of the double-groove yarn guide wheel 18.

[0081] like Figure 1 As shown, the segment colored yarn spinning frame further comprises a roving guide rod 4. The roving guide rod 4 is used to guide the auxiliary color roving c to the rear bell mouth and feed the rear roller.

[0082] The method for producing segment color plied yarn by using the segment color plied yarn spinning frame in the present application is as follows:

[0083] The auxiliary color roving c suspended on the roving frame 3 is guided by the roving guide rod 4, passes through the rear bell mouth 10, is intermittently fed through the rear roller 12, and enters the middle roller 13 and the middle leather roller 16 as well as the front roller 14 and the front leather roller 17 through the middle bell mouth 11 for drafting;

[0084] The yarn a and the yarn b suspended on the yarn hanging rod enter the two grooves of the double-groove yarn guide wheel 18 respectively through the yarn guide hooks 6 and 7, the yarn guide rods 2 and 5, and the yarn guide hooks 8 and 9, and the yarn a and the yarn b are guided to the front roller 14 and the front leather roller 17 by the double-groove yarn guide wheel 18; then they are twisted to form segmented colored strands 21, which are guided by the yarn guide hooks 24 and the yarn guide plates 23 and wound on the spun yarn tube 24.

[0085] Among them, at the front roller 14 and the front leather roller 17, when the front roller 14 and the front leather roller 17 hold the yarn, the auxiliary color roving c is located between the yarn a and the yarn b.

[0086] Example 2

[0087] 32S / 1 carded white yarn is used as a and b yarns. Raw cotton and dyed black cotton are used as raw materials, with 30% raw cotton and 70% black cotton.

[0089] Table 1

[0090]

[0091] The pitch is the length of the segment color strands without auxiliary color roving; the section length is the length of the segment color strands with auxiliary color roving; when spinning randomly, the pitch lengths are randomly selected from several groups to avoid regular cycles; the transmission ratio is the speed of feeding the auxiliary color roving.

[0092] During the implementation process, two 32S / 1 white yarns are fed into the front roller via the yarn guide rod 2, yarn guide hooks 6, 7, 8, 9, and double groove yarn guide wheel; the dark hemp gray auxiliary color roving c is fed into the front roller 14 via the yarn guide rod 4, the rear bell mouth 10, the rear roller 12, the middle bell mouth 11, and the middle roller 13, and is located in the middle of the two 32S / 1 yarns. After spindle twisting, the fiber bundle formed by the two 32S / 1 and the dark hemp gray roving after drafting is used to make the 28S / 2 hemp gray segment color strand in the twisting triangle area. Figure 4 It is a schematic diagram of the effect of weaving a plain fabric using the segmented color ply yarn prepared by the above method of this embodiment on a flat knitting machine.

[0093] Example 3

[0094] 32S / 1 combed white yarn is used as a and b yarns. Raw cotton and dyed red cotton are used as raw materials, with 40% raw cotton and 60% red cotton. After cotton blending, cotton blending, cotton cleaning, cotton carding, drawing and roving, red auxiliary color roving is obtained, with a roving weight of 6.3g / 10m.

[0095] On the three-roller spinning frame body of the segment color strand spinning frame, the segment color parameters are set as shown in Table 2 below, in order to obtain short segments of red segment color strands.

[0096] Table 2

[0097]

[0098] During the implementation process, two 32S / 1 white yarns are fed to the front roller via the yarn guide rod 2, yarn guide hooks 6, 7, 8, 9, and double groove yarn guide wheel; the red auxiliary color roving c is fed to the front roller 14 via the yarn guide rod 4, the rear bell mouth 10, the rear roller 12, the middle bell mouth 11, and the middle roller 13, and is located in the middle of the two 32S / 1 yarns. After spindle twisting, the fiber bundle formed by the two 32S / 1 and the red roving after drafting is obtained in the twisting triangle area to obtain 28S / 2 red segment color strands.
