Technical Field

[0001] The invention relates to the field of spinning, in particular to AB style slub roving, spun yarn, fabric and a production method thereof. Background Art

[0002] AB yarn is a key appearance style product in the textile field. It uses A roving and B roving of the same quantity but different colors. On the spinning machine, they are inserted into the left and right holes of the rear bell mouth at the same time. After being stretched in the drafting area composed of the front, middle and rear rollers and leather rollers, fiber slivers A and B of different colors are formed. After being twisted and wound on the spinning spindle, AB yarn with a twist effect is produced.

[0003] Currently, AB yarn is produced in the spinning process. However, traditional AB yarn has a monotonous style due to the same A and B roving weights, resulting in a 50% A and B content. Furthermore, traditional AB yarn only comes in two colors, A and B, which is monotonous. These characteristics limit the promotion and application of AB yarn. Summary of the Invention

Figure 1As shown, along the processing direction of the yarn, the roving spinning device includes a first guide roller 1, a yarn hanging rod 2, a second guide roller 3, a rear roller 5, a middle roller 8, a front roller 10 and a roving spindle 13 in sequence; a rear top roller 6 matching therewith is provided near the rear roller 5; a middle top roller 9 matching therewith is provided near the middle roller 8; a front top roller 11 matching therewith is provided near the front roller 10; a three-hole rear bell mouth 4 is provided upstream of the rear roller 5, and a three-hole middle bell mouth 7 is provided upstream of the middle roller 8; the three-hole rear bell mouth 4 and the three-hole middle bell mouth 7 are both formed with three yarn guide holes arranged side by side;

[0053] The spinning device further comprises a main motor and a servo motor M, wherein the front roller 10 and the middle roller 8 are transmission-connected to the main motor; and the rear roller 5 is transmission-connected to the servo motor M.

[0054] In this application, a three-hole rear bell mouth 4 and a three-hole middle bell mouth 7 are used to separate and orient the fiber strips fed into the drafting zone, thereby ensuring that the drawn strips A, drawn strips B and roving C are each drafted separately in the drafting zone composed of the rear roller, middle roller and front roller, and then converge in the twisting triangle area between the front roller and the roving spindle to form AB style bamboo roving, which ensures the stability and continuity of the production method and improves production efficiency.

[0055] According to the roving spinning device described above, it also includes a bobbin 14, which is arranged downstream of the roving spindle 13. It is used to wind the continuously obtained AB style bamboo roving during production. When the sliver A, sliver B and roving C are used to produce AB style bamboo roving through the roving spinning device, the sliver A and sliver B are fed into the three-hole rear bell mouth 4 through the first guide roller 1 and the third guide roller 3, and the roving C is set on the yarn hanging rod 2. The roving C is fed into the three-hole rear bell mouth 4 through the third guide roller 3; the roving A, sliver B and roving C are respectively stretched by the back roller 5 and the back leather roller 6, the middle roller 8 and the middle leather roller 9, the three-hole middle bell mouth 7, the front roller 10 and the front leather roller 11, and then twisted by the roving spindle 13 to form AB style bamboo roving, which is wound on the bobbin 14. Among them, the drawn slivers A and drawn slivers B are respectively fed into the left yarn guide hole and the middle yarn guide hole of the three-hole rear bell mouth 4 through the first guide roller 1; the coarse yarn C is fed into the right yarn guide hole of the three-hole rear bell mouth 4 through the third guide roller 3; the drawn slivers A and drawn slivers B are respectively fed into the left yarn guide hole and the middle yarn guide hole of the three-hole middle bell mouth 7; the coarse yarn C is fed into the right yarn guide hole of the three-hole middle bell mouth 7.

[0056] In the present application, the servo motor independently controls the continuous operation of the rear roller to control its rotation speed, thereby controlling the drafting multiple and forming the bamboo joint feature.

[0071] Slub process, pitch 120mm±30%, section length 30mm±30%, slub multiple 1.5 times. (±30% means that during the spinning process, there will be random changes within the range of plus or minus 30%).

[0072] The multi-color AB slub roving prepared above is then passed through a ring spinning frame to produce red, blue, and green AB style slub yarn. Compared with the traditional AB slub yarn prepared directly by the spinning process, the yarn in the embodiment of the present application has multiple colors and a more rugged style.

[0073] Example 4

[0078] The multi-color AB style roving was obtained through production, with a basis weight of 7.0 g / 10 m and a roving twist of 4.3 T / 10 cm.

[0079] Among them, in the coarse yarn process, the drafting ratio between the front roller and the middle roller is 8.3 times; the servo motor controls the speed change of the rear roller, and the average speed of the rear roller is 8.9% of the speed of the front roller, that is, the total drafting ratio of the front roller and the rear roller is 11.2 times.

[0080] Slub process, pitch 180mm±25%, section length 40mm±25%, slub multiple 1.8 times. (±25% means that during the spinning process, there will be random variation within the range of plus or minus 25%).

[0081] The blue, black and green AB slub roving prepared above is then passed through a ring spinning frame to produce a blue, black and green AB style slub yarn. Compared with the traditional AB slub yarn prepared directly by the spinning process, the yarn in the embodiment of the present application has multiple colors and a more rugged style.

[0082] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
