[0036] When in use, firstly, the disc 1 is divided into N large areas by using the disc dividing piece 9, wherein the value of N is between 2 and 6, and the required proportion of lyocell, ibingfeng polyester, polylactic acid and tencel fibers are stacked in each area. At this time, one side of the first disc dividing piece 9 is embedded in the disc dividing piece embedding groove 8 of any first dividing piece inner connecting device, and then the fixed magnet 10 on the other side of the disc dividing piece 9 is rotated and adsorbed on the outer surface of the disc 1 at any position, so as to fix the disc dividing piece 9, and then the first fixed point of the first disc dividing piece 9 on the outer surface of the disc 1 is taken as the starting point, and 1 / N of the circumference is rotated in a clockwise or counterclockwise direction to obtain the first disc dividing piece 9.

[0037] The automatic mixing process adopts an automatic cotton mixing machine. The mixed fibers conveyed are highly sorted by the upper cotton box and then output by the swinging bucket, thereby forming a mixed fiber layer at the bottom of the upper cotton box. The mixed fiber layer is driven by the cotton conveying curtain and grabbed by the corner nail curtain along the thickness direction, thereby achieving uniform mixing of the four fibers in the grabbing process. The fibers grabbed by the corner nail curtain are uniformly sorted by the pressing cotton curtain and the cotton balancing roller in turn during the conveying process, and then grabbed by the first beater close to the corner nail curtain. The grabbed mixed fibers are then grabbed by the second beater close to it, thereby achieving the free striking and loosening effect on the mixed fibers, and then the mixed fibers are conveyed to the automatic packaging process through the pipeline driven by the negative pressure airflow.

[0038] The automatic packaging process uses an automatic packaging machine to package the premixed materials, thereby obtaining mixed fiber packages to be processed and in accordance with the required mixing ratio.

[0039] The third step: forming mixed fibers into strips. The mixed fiber packages obtained in the second step are sequentially subjected to cotton grabbing, cotton blending, cotton opening and cotton carding to obtain mixed fiber strips.

[0040] A disc-type cotton plucking machine is used in cotton plucking, and the mixed fiber packages obtained in the second step are stacked in the disc, and the stacked mixed fibers are kept at a consistent height along the circumferential direction in the disc. Then the cotton plucking trolley is driven by the control column to rise and fall until it is in pressing contact with the fibers on the upper part of the disc. The cotton plucking trolley is then driven by the control column to rotate along the circumferential direction of the disc, thereby completing the grabbing of the fibers along the circumferential direction of the disc. The grabbed fibers are transported to the cotton mixing process through the pipeline under the drive of the negative pressure airflow.

[0041] The cotton blending process uses a multi-bin cotton blending machine, which includes a first multi-bin cotton blending machine and a second multi-bin cotton blending machine that are cascaded with each other in pipelines. The first multi-bin cotton blending machine uses a time difference mixing method, and the second multi-bin cotton blending machine uses a distance difference mixing method. The conveyed mixed fibers first enter the first multi-bin cotton blending machine. During this process, the conveyed mixed fibers are sequentially conveyed to each cotton bin of the first multi-bin cotton blending machine, and different heights are formed in each cotton bin, and then the mixed fibers in each cotton bin are simultaneously output. , thereby realizing time difference mixing under different feeding and simultaneous output. The mixed fibers output by the first multi-bin cotton mixer are then transported to the second multi-bin cotton mixer through the pipeline. During this process, the transported mixed fibers are simultaneously transported to each cotton bin of the second multi-bin cotton mixer, and form the same height in each cotton bin. Then the mixed fibers in each cotton bin are output after passing through elbows of different lengths, thereby realizing distance difference mixing under different output distances under simultaneous feeding. The mixed fibers are transported to the cotton opening process through the pipeline driven by the negative pressure airflow.

[0042] The cotton opening process adopts a combing needle beater cotton opening machine. The conveyed mixed fibers enter the upper cotton box, are stacked to a certain height, and are gripped and output by rollers. During the gripping and outputting process, they are hit and loosened by the rotating combing needle beaters. The mixed fibers that have been hit and loosened are completely transferred to the combing needle beaters, and are continued to be conveyed under the support of the impurity removal device at the bottom of the combing needle beaters until they are output from the fiber delivery port under the action of negative pressure airflow. The output mixed fibers are transported to the cotton combing process through pipelines.

[0043] The carding process uses a carding machine with a cotton feeding box. The conveyed mixed fibers first enter the cotton feeding box, where they are evenly arranged and then continuously conveyed to the carding machine. In the carding machine, the mixed fibers are gripped and struck to loosen by the licker-in rollers in turn, freely transferred and combed by the cylinder and cover plate rotating in the same direction, condensed into a web by the doffer, and gathered into strips by the trumpet mouth to obtain the required mixed fiber strips.

[0044] Step 4: Mix the fibers to form yarn. The mixed fiber strips obtained in the third step are sequentially subjected to three stages of drawing, roving, spun yarn, and winding to obtain blended bobbin yarn.

[0045] The drawing process uses a drawing frame. The first drawing process uses 6 mixed fiber strips to feed. The 6 mixed fiber strips fed are gathered and enter the drafting system. After being stretched by more than 1.5 times in the back zone and 6-6.5 times in total, they are gathered again to obtain a mixed fiber finishing strip.

[0046] The second drawing process uses 7 mixed fiber finishing strips to feed. The 7 mixed fiber finishing strips fed are gathered and enter the drafting system. After the drafting action of 1.3-1.5 times in the back zone and 6.8-7.1 times in total, they are gathered again to obtain semi-ripened mixed fiber strips.

[0047] The third drawing process uses 8 semi-ripe mixed fiber strips to feed. The 8 semi-ripe mixed fiber strips are gathered and enter the drafting system. After being stretched by 1.1-1.3 times in the back zone and 7.6-8 times in total, they are gathered again to obtain mixed fiber ripe strips.

[0048] The roving process adopts a suspended spindle wing roving frame, which adopts one mixed fiber sliver for feeding. The mixed fiber sliver is stretched within 10 times to obtain mixed fiber whiskers. In this process, the fibers in the mixed fiber sliver are speed-changed under the control of the external friction field generated by the stretching device. The mixed fiber whiskers are twisted into the required blended roving after the twisting twist generated by the rotation of the spindle wing. The blended roving is driven by the rotation of the spindle in the same direction as the spindle wing but at a different linear speed and then wound on the roving tube. The rotation linear speed of the spindle is greater than the rotation linear speed of the spindle wing. The difference in linear speed between the two makes the blended roving continuously wound on the roving tube.

[0049] The spinning process adopts a ring spinning frame, and two blended rovings are fed. The two blended rovings fed are kept at a certain distance, and are independently stretched by 20-80 times to obtain the first whisker and the second whisker that keep a certain distance, and the distance between the first whisker and the second whisker is smaller than the distance between the two blended rovings fed. During the stretching process, the fibers in the blended roving are changed in speed under the coordinated control of the external friction field generated by the stretching device and the internal friction field formed by the entanglement between the fibers. The output first whisker and the second whisker are respectively realized along the width of the whisker by the negative pressure. The first and second whiskers are gathered in the direction of degree, and the gathered first and second whiskers are twisted into the initial blended yarn after the twisting twist generated by the passively rotating wire ring. In this process, the first whisker and the second whisker are weakly twisted into the first sub-yarn and the second sub-yarn respectively under the action of the transmitted twisting twist, and the first sub-yarn and the second sub-yarn are strongly twisted with each other into the initial blended yarn under the action of the transmitted upward twisting twist. The initial blended yarn is driven by the actively rotating spindle and then wound on the spinning tube. The rotation speed of the spindle is converted into the rotation speed of the wire ring on the one hand, and is converted into the winding speed of the initial blended yarn on the other hand.

[0050] The bobbin winding adopts a tray-type automatic bobbin winding machine. The initial blended spun yarn is unwound from the spun yarn tube and then enters the electronic yarn clearer for yarn defect removal. During the unwinding process of the initial blended spun yarn, the spindle speed converted into the winding speed of the initial blended spun yarn is reconverted into the twisting twist of the spun yarn, so that the rotation speed of the spindle is completely converted into the twisting twist of the spun yarn, and then the required blended spun yarn is obtained. The blended spun yarn with yarn defect removal is continuously wound on the bobbin, and then the blended bobbin yarn is obtained.

[0051] The fifth step is to prepare the desired comfortable health-care fabric by weaving the blended cone yarn prepared in the fourth step.

[0052] A part of the blended bobbin yarn is directly used as weft yarn, and the other part of the blended bobbin yarn is directly wound on the warp beam after warping, so as to obtain the warp yarn for weaving. The weft yarn and the warp yarn are processed by a bidirectional weft-insertion air-jet loom to obtain the desired comfortable health-care fabric.

[0053] Taking the blended yarn with a production line density of 11.8tex and a blending ratio of 40 / 30 / 20 / 10 of lyocell, ibingfeng polyester, tencel and polylactic acid fiber and the corresponding fabric as an example, the following process design is adopted:
