The present invention will be described in detail with reference to fig. 1, 2 and 3. The invention relates to a spinning processing preparation process of antibacterial composite knitting yarn, which comprises the following steps:
s1, selecting raw materials: wool fibers are selected as the cover fibers and antimicrobial fibers are selected as the raw materials of the core yarns.
S2, preparing core yarns: the antibacterial fiber and the blend fiber are made into blend yarn which is used as core yarn.
S3, mixing: wool fibers as the covered fibers were subjected to opening mixing, and wool was sprayed with a wool-and-wool mixed solution, followed by wool-and-wool treatment.
S4, carding: and (3) preparing the wool fibers subjected to the sum wool into raw strips through a carding process.
S5, needle comb: and (3) preparing the prepared raw strips into the needle-combed wool tops through a 2-needle-combed process.

S7, preparing a twistless roving: and (5) preparing the wool tops subjected to drawing into non-twist slub by adopting non-twist slub equipment.
S8, preparing a core-spun composite yarn: the core yarn and the roving are made into the antibacterial composite knitting yarn by adopting core yarn production equipment, the core yarn and the cladding fiber have opposite twisting directions, and the twisting degree of the core yarn and the twisting degree of the cladding fiber are controlled according to 0.45-0.6:1.
Further, the antibacterial composite knitting yarn prepared by the knots is subjected to count design. In the step S1, the selected antibacterial fiber may be a moxa cotton fiber, and the blend fiber mixed with the antibacterial fiber selected in the core yarn may be a natural fiber or a chemical synthetic fiber such as cotton, wool, cashmere, terylene, chinlon, acrylon, etc. And the coated fiber can be 66S-110SZ common Australian wool, balano wool, mercerized Australian wool or shrink-proof Australian wool and the like. The design ensures that the content of the final finished product of the moxa cotton fiber is not less than 30 percent; the coated fiber in this example was selected to be 70S mercerized australia wool. The core yarn was produced according to a 55% cotton, 40% Ai Caomian, 5%70S mercerized Australian wool 20Nm/1 blend design. The fineness of the finally prepared antibacterial composite knitting yarn is 60Nm/1.
Further, in step S2, the fineness of the prepared blended yarn is 20Nm/1, the twisting direction is S, and the twist degree can be selected according to actual needs, and in this embodiment, is selected to be 200 twists/m.
Further, in the step S3, the mixed solution of the sum and the wool comprises 3 to 4 percent of sum and the wool oil, 0.5 to 0.7 percent of antistatic agent, 0.5 to 1 percent of yarn reinforcing agent and water; the addition agent is prepared by mixing wool fiber with water in an amount of 20-22% by weight. In particular to this example, the wool blend solution included 3.5% and wool oil, 0.6% antistatic agent, 0.8% yarn enhancer, and water.
Further, in step S4, the carding equipment used is a wool spinning roller type carding machine; compared with a cotton spinning cover plate type carding machine, the wool spinning roller type carding machine is changed from hard holding with great damage to fibers to elastic holding of fibers with low strength and easy carding, such as wool, down and the like.
The wool spinning roller type carding machine comprises a wool bucket, a licker-in, a pre-carding cylinder, a main cylinder, doffers and a wool stripping device which are sequentially arranged on a frame; the pre-carding system is characterized in that three groups of working rolls and stripping roll combinations are arranged on the pre-carding cylinder, a transfer roll is arranged between the pre-carding cylinder and the main cylinder, and a cover plate is arranged on the main cylinder; the pre-carding system is composed of 3 pairs of working rolls, 84 carding cover plates, and 30 main carding systems are composed of working cover plates.
The carding machine is held for elasticity for the carding machine except that the feed roller holds, has still increased 3 pairs of working rolls's pre-carding system, and the carding apron reduces to 84 from original 106, and main carding system adopts 30 working apron, and apron four-point gauge is 9, 10, 12 english silk respectively. Tin Lin Zhuaisu can be reduced by 100 revolutions per minute compared with a carding machine, and the carding is softer and less damaged.
The carding process takes main fibers of raw materials as selection basis, and according to the length of the main fibers of 45-50mm of the raw materials, the process parameters are as follows:
the group of working rolls and the hair stripping rolls close to the licker-in are a first group, the group of working rolls and the hair stripping rolls close to the main cylinder are a third group, and the middle working rolls and the hair stripping rolls are a second group; the working rolls in the first group have a gauge of 20-22 filament, the dehairing rolls have a gauge of 21-22 filament, the working rolls in the second group have a gauge of 18-20 filament, the dehairing rolls have a gauge of 22 filament, and the working rolls in the third group have a gauge of 16-18 filament and the dehairing rolls have a gauge of 22 filament. The large-gauge pre-carding pre-combs the bundled fibers to form finer bundled fibers, so that the fibers are easier to comb, the fiber damage caused by carding is reduced, the fiber length can be increased by 5mm, the short velvet content is reduced, and an important effect on improving the quality of yarns is achieved.
Further, in step S5, a small pitch pin plate gill box is used in the gill process. The two small-roller-distance needle plate gill boxes are adopted, so that the drafting distance (the lowest adjustable length is 24 mm) can be effectively reduced, the front and back hooks of the fibers can be effectively eliminated, the fibers are more straightened, parallel and separated, the fibers are elastically held, the accidental drafting is reduced, and the fibers cannot be broken. In addition, the 2-channel needle carding process is selected, and because the needle carding process is overlong, the number of the wool grains in the wool tops is increased due to the striking of the needle plate, the quality control of the wool tops is not facilitated, the straightness of the fibers can be ensured by 2-channel needle carding, and the number of the wool grains can be prevented from increasing.
Further, the evenness of the wool tops manufactured through 2-channel needle carding is poor and does not compound production requirements, and in order to avoid that the wool tops are increased due to overlong needle carding procedures and influence product quality, 2 drawing procedures are selected, and the final drawing is of an auto-leveling machine type, so that on one hand, uneven weight of the wool tops is greatly reduced, the uneven weight of the wool tops is controlled within 1.5%, on the other hand, the straightening, parallel and separation degree of wool top fibers is ensured, and the generation of wool tops is reduced.
Further, in step S7, the roving produced by the roving frame has a larger width than the strands of the roving produced by the roving frame before the spinning frame, and has a good effect of improving the problem of poor filament coating of the core spun yarn. The roving equipment and the drafting gauge are adjusted to be smaller, the front area is 25mm, and the total gauge is 110mm; the draft multiple is designed to be smaller and controlled to be between 5.5 and 7.5 times; the tension of each yarn guiding area is widened to 1X; the bundling device is small in size, and fiber cohesion is increased; the speed of the rubbing board is increased to 110-120m/min, the evenness is controlled below 5%, and the weight unevenness is controlled below 1.0%.
Further, the core-spun yarn production equipment comprises a core yarn twisting device 1 and a core-spun yarn device 2;
the core yarn 6 is twisted by the core yarn twisting device 1, the twisted core yarn 6 is fed into the core-spun yarn device 2, the outside of the core yarn 6 is covered with the spun yarn, and the twisting direction of the spun yarn is opposite to the twisting direction of the core yarn 6. Because of the opposite twisting directions, the prepared single-strand core-spun yarn can balance the influence caused by the twisting directions, and the phenomenon that the single yarn is inclined when used for weaving sweaters is avoided. .
The core yarn twisting device 1 comprises a yarn storage disc 3, wherein a hollow spindle rod 21 is arranged on the yarn storage disc 3, and a core yarn roll 4 is arranged on the hollow spindle rod 21. After the core yarn 6 is led out from the core yarn roll 4, the core yarn penetrates into the hollow spindle 21 from the upper part of the hollow spindle rod 21 and penetrates out from the lower part of the hollow spindle rod.
The core-spun yarn device 2 comprises a ring twisting and winding device 9, a drafting device and a roving feeding device 11; the drafting device comprises a rear roller 13, a middle roller 14 and a front roller 15, wherein the rear roller 13 is close to the roving feeding device 11, and the front roller 15 is close to the ring twisting and winding device; the middle roller 14 is provided with a rubber ring 16; the roving feeding device 11 is provided with a roving roll; a first yarn guiding device is arranged between the ring twisting and winding device 9 and the drafting device. The first yarn guiding device is a fourth yarn guiding hook.
A second yarn guiding device is arranged above the yarn storage disc 3, and the core yarn 6 led out from the core yarn roll 4 passes through the hollow spindle rod 21 to the lower part of the yarn storage disc 1, is guided by the second yarn guiding device and is fed into the front roller 15. The second yarn guiding device comprises a first yarn guiding hook 5, a second yarn guiding hook 7 and a third yarn guiding hook 8.
The working process of the wool spinning composite yarn production equipment is as follows: after being led out from the core yarn roll 4, the core yarn 6 passes through the hollow spindle rod 21 from top to bottom, passes out from the lower part of the yarn storage disc 3, and passes through the first yarn guide hook 5, the second yarn guide hook 7 and the third yarn guide hook 8 in sequence. During unwinding of the core yarn 6 from the core yarn roll 4, the core yarn 6 moves along the outside of the yarn storage disc 3 and has a twisting effect on the core yarn 6.
The twisted core yarn is guided to a draft device.
