Description

Technical Field

[0001] The present invention relates to the new technical field of spinning, in particular to a device and method for producing colored spun wool yarn. Background Art

[0002] Air-jet yarn, a new type of fancy yarn originating in Italy and known as "Air Yarn," was invented and patented by a foreign fancy yarn manufacturer in 1994. Due to the patent's protection, this yarn was monopolized by only one or two manufacturers worldwide, resulting in high prices. The patent was lifted in 2008, and development and production began in China. Air-jet yarn breaks away from the traditional twisting of yarns. It utilizes weft knitting to create hollow tape yarns. The fibers of the roving, combed by a combing roller, are then sprayed into a mesh tape, creating a yarn with a net-like structure that wraps the loose fibers. The fibers are loose and disordered, resulting in a soft, fluffy, and warm yarn. At the same count, the yarn is larger, and the yarn used for a single garment is approximately 30% lighter than conventional yarn. Air-jet yarn is primarily produced by spinning the roving, which is then processed on a spraying machine.

[0003] Since the 21st century, people have increasingly demanded higher standards for clothing design. They are not only satisfied with comfort and appropriateness, but also pay more attention to the external aesthetics of clothing. Visual impact often stimulates consumers' primary desire to consume. Therefore, these demands have brought various opportunities and challenges to the traditional textile industry. Seaweed fiber is a type of man-made fiber. It refers to a bio-based fiber made by spinning sodium alginate extracted from marine algae. Seaweed fiber has good affinity with human skin, antibacterial properties, moisture absorption and breathability, and can achieve a pilling resistance level of 3-4. In response to this, this patent introduces seaweed fiber into the production of spray yarn. The seaweed fiber is blended with fibers such as acrylic and polyester to produce coarse yarn, which is then processed on a spray machine to produce color-spun spray yarn. Summary of the Invention

[0014] The above-mentioned method for producing a color-spun spray-wool yarn, wherein preferably, the method for producing a color-spun spray-wool yarn comprises the following steps:

[0015] The first step: processing of wool-jet colored roving, wherein the selected fibers are subjected to a semi-worsted spinning process to obtain wool-jet colored roving including red wool-jet roving, green wool-jet roving and blue wool-jet roving. The semi-worsted spinning process includes dyeing, wool blending, wool suffusing, wool combing, drawing and roving;

[0016] The second step is to process the color-spun wool yarn, wherein the red wool-spun roving, green wool-spun roving, blue wool-spun roving and regenerated semi-dull polyester filament prepared in the first step are fed into the color-spun wool-spun roving production device to prepare the color-spun wool-spun roving;

[0017] The red, green and blue wool-jet rovings are passed through the first, second and third roller sleeves of the lower control roller respectively, and then the three are passed through the lower output roller sleeve of the lower output roller together, and then the pressure component is pressed down, so that the upper control rubber roller is pressed down, and then the first, second and third rubber roller sleeves of the upper control rubber roller are tightly pressed against the first, second and third roller sleeves of the lower control roller respectively, thereby forming the first, second and third rear pressing and holding input jaws for the red, green and blue wool-jet rovings, respectively, and at the same time the upper output rubber roller is pressed down, so that the upper output rubber roller of the upper output rubber roller is pressed down. The sleeve is tightly pressed against the lower output roller sleeve of the lower output roller, thereby forming a front pressing and holding output jaw for the mixed color strands. During the first rear pressing and holding input jaw for inputting the red wool-jet roving, the first motor drives the first driving shaft to rotate, and then drives the first driving drum to rotate through the first driving belt, and then drives the first roller sleeve to rotate, and then drives the first rubber roller sleeve to rotate synchronously, thereby actively driving the red wool-jet roving input, thereby realizing the adjustment of the feeding speed of the red wool-jet roving by adjusting the speed of the first motor. During the second rear pressing and holding input jaw for inputting the green wool-jet roving, the second motor drives the second driving shaft to rotate, and then drives the second driving drum to rotate through the second driving belt, and then drives the second roller sleeve to rotate, and then drives the second roller sleeve to rotate, The second rubber roller sleeve is driven to rotate synchronously, thereby actively driving the input of green wool-jet roving, thereby realizing the adjustment of the feeding speed of green wool-jet roving by adjusting the speed of the second motor. During the process of inputting blue wool-jet roving by pressing the input jaw, the third motor drives the third driving shaft to rotate, and then drives the third driving drum to rotate through the third driving belt, and then drives the third roller sleeve to rotate, and then drives the third rubber roller sleeve to rotate synchronously, thereby actively driving the input of blue wool-jet roving, thereby realizing the adjustment of the feeding speed of blue wool-jet roving by adjusting the speed of the third motor. The fed red wool-jet roving, green wool-jet roving and blue wool-jet roving are then gripped and output by the front pressing and gripping output jaw, and the gripping output speed is greater than the gripping input speed. degree, so that the red jet-wool roving is subjected to the first stretching effect of the ratio between the conveying speed of the front pressing and holding output jaws and the input speed of the first rear pressing and holding input jaws. Under the first stretching effect, the linear density of the red jet-wool roving is reduced, and a red jet-wool whisker with a certain twist is obtained, and the ratio of the residual twist of the red jet-wool whisker to the twist of the red jet-wool roving is inversely proportional to the first stretching. At the same time, the fibers in the red jet-wool whisker are further straightened, and the green jet-wool roving is subjected to the second stretching effect of the ratio between the conveying speed of the front pressing and holding output jaws and the input speed of the second rear pressing and holding input jaws. Under the second stretching effect, the linear density of the green jet-wool roving is reduced, and a green jet-wool whisker with a certain twist is obtained.The ratio of the residual twist of the green jet-wool whiskers to the twist of the green jet-wool roving is inversely proportional to the second drafting. At the same time, the fibers in the green jet-wool whiskers are further straightened, so that the blue jet-wool roving is subjected to a third drafting action of the ratio between the conveying speed of the front pressing and holding output jaw and the input speed of the third rear pressing and holding input jaw. Under the action of the third drafting, the linear density of the blue jet-wool roving is reduced, and a blue jet-wool whisker with a certain residual twist is obtained. The ratio of the residual twist of the blue jet-wool whiskers to the twist of the blue jet-wool roving is inversely proportional to the third drafting. At the same time, the fibers in the blue jet-wool whiskers are further straightened.

[0018] The output red, green and blue hair strands are immediately loosened and grabbed by the first opening card cloth of the first opening roller. During this process, the first opening roller rotates clockwise, so that the first opening card cloth grabs the hair strands. During the grabbing process, the needle teeth of the first opening card cloth distributed along the length direction of the middle roller shaft separate the hair strands along the width direction, and the needle teeth on the first opening card cloth distributed along the circumference direction of the middle roller shaft separate the hair strands along the width direction, thereby respectively making the red, green and blue hair strands loosened and grabbed by the first opening card cloth. The fibers on the sprayed hair strips and blue sprayed hair strips are transferred to the first combing roller in the form of multiple fiber bundles. During the grabbing process, the twist remaining in the red sprayed hair strips, green sprayed hair strips and blue sprayed hair strips makes the hair strips maintain a relatively stable shape when being grabbed by the first combing roller, thereby achieving uniform and stable grabbing. In the bundle splitting process, the hair strips are split into strands and then the twist of the hair strips is divided, thereby achieving uniform and consistent segmentation of the hair strips in the circumferential direction. The fiber bundles grabbed by the first combing needle clothing are grabbed by the first combing roller. The fiber bundles caught by the second combing needle cloth are driven by the second combing roller and transported downward along the circumferential direction of the second combing roller;

[0019] The sixth motor drives the drum to rotate through the fourth drive belt, and then drives the mixing cup to rotate synchronously. During the high-speed rotation of the mixing cup, centrifugal force is generated. Under the action of the centrifugal force, the external air flow enters from the top of the mixing cup and then flows out from the air outlet on the mixing ring, thereby forming a certain air flow in the mixing cup. Under this air flow, the fibers rotated to the lower part of the second combing roller fall into the mixing cup. Under the action of the air flow and centrifugal force in the mixing cup, the fibers slide along the inner side of the mixing cup and then slide to the mixing ring. At the mixing ring, the fibers of different colors are merged along the axial direction of the mixing ring to obtain mixed colors. The fiber ring can achieve uniform mixing of three different colors of fibers during multiple merging processes. As the merging increases, the diameter of the mixed color fiber ring increases, and the air flow out of the air outlet decreases, thereby reducing the amount of fibers falling from the lower part of the second combing roller into the mixing cup, and these falling fibers will continue to slide into the mixing ring for merging. At the same time, a part of the air flow entering from the top of the mixing cup flows from the bottom end of the driving cylinder into the cavity of the spray gun device, so that under this air flow, the mixed color fiber ring enters the cavity of the spray gun device from the bottom end of the driving cylinder. As the mixed color fiber ring falls, the air flow out of the air outlet is reduced. The amount of fibers dropped from the lower part of the second combing roller into the mixing cup increases accordingly, and these dropped fibers will continue to slide into the mixing ring for merging, thereby forming a dynamic balance in the mixing cup. The mixed fibers dropped into the cavity of the spray gun device are sprayed into the regenerated semi-dull polyester filament fiber mesh belt formed by the filament web forming device under the action of the compressed air gun to form a colored spun yarn. During the operation of the compressed air gun, the air inhaled from the outwardly arranged air flow input hole and the external air entering the cavity of the spray gun device from the bottom end of the driving cylinder are compressed to obtain the compressed air flow required for high-speed injection of the compressed air gun, and then Under this compressed air flow, the mixed-color fiber ring is ejected at high speed. During the processing of the fiber mesh belt, the needle cylinder performs a cyclic rotation motion, and then the cam in the shell drives the crochet hook to move up and down. When the crochet hook reaches the highest point, the woven coil slides under the needle tongue. When the crochet hook is lower than the needle cylinder mouth due to the rotation of the needle cylinder, the original old coil under the crochet hook slides off the crochet hook to form a new coil, thereby continuously rotating to form a regenerated semi-dull polyester filament fiber mesh belt. The output color-spun yarn is ring-detwisted by the detwisting winding device to fully detwist and ensure the fluffy characteristics of the yarn. The color-spun yarn after detwisting is continuously wound on the copper tube.

[0020] Compared with the prior art, the present invention selects 50dtex / 24F DTY regenerated semi-dull polyester filament as the raw material of the mesh belt, which contains 80% polyester staple fiber with a specification of 1.5dtex×38mm, 10% 66S mohair, and 10% seaweed fiber with a specification of 1.67dtex×38mm as the raw material, and the blended roving is dyed with the blended loose wool to make three kinds of rovings of red, green and blue. The three colors of blended rovings are fed separately through three roller sets with consistent diameters and drive shafts nested with each other to form independent transmission control, so that the feeding speed control of rovings of different colors is achieved by controlling the rotation speed of each roller set, and the rovings of different colors fed are successively struck and loosened by the first combing roller, and then combed and grabbed to obtain fiber bundles, and then passed through the second combing roller. The two combing rollers carefully comb and grab the loose fibers, which fall into the mixing cup under the action of the airflow generated in the high-speed rotating mixing cup located at the bottom of the second combing roller and their own gravity, and are merged multiple times at the mixing ring with the largest diameter in the mixing cup, thereby obtaining a mixed-color fiber ring with a uniform mixing effect. When the mixed-color fiber ring is sealed through the pores at the mixing ring, the mixed-color fiber ring falls into the cavity of the spray gun under the action of its own gravity and airflow. The mixed-color fiber ring in the cavity of the spray gun is sprayed into the fiber mesh belt formed by the regenerated semi-dull polyester filament driven by the syringe under the high-speed air pressure of the spray gun, thereby obtaining a colored spun yarn with a uniform color mixing effect and thermal insulation, health care and antibacterial effects.

[0029] The color fiber mixing device includes a mixing cup 17, which is located directly below the second combing roller 14. The mixing cup 17 is a hollow cylinder with open ends. The diameter of the mixing cup 17 gradually increases from top to bottom along the height direction of the mixing cup 17, then gradually decreases until it remains unchanged, thereby forming a mixing ring at the maximum diameter in the middle upper part of the height of the mixing cup 17.

[0032] In a second aspect, the present invention provides a method for producing a color-spun spray-wool yarn, the color-spun spray-wool yarn comprising an outer fiber mesh belt and a core spray-wool color-spun roving, wherein the fiber mesh belt is made of 50dtex / 24F DTY regenerated semi-dull polyester filament, and the spray-wool color-spun roving is made of red, green, and blue blended rovings made by dyeing 10% of original seaweed fiber, 80% of polyester, and 10% of mohair loose hair, wherein the average linear density of the selected polyester is 1.5dtex and the average length is 38mm, the average linear density of the selected mohair fiber is 66S, and the average linear density of the selected seaweed fiber is 1.67dtex and the average length is 38mm. The method specifically comprises the following steps:

[0033] The first step: processing of wool-spray colored roving, the selected fibers are processed through semi-worsted process to obtain wool-spray colored roving including red wool-sprayed roving, green wool-sprayed roving and blue wool-sprayed roving. The semi-worsted process includes dyeing, wool blending, wool stuffing, wool combing, drawing and roving. In order to increase the cohesion of the fibers, reduce the hardness of the fibers and reduce the losses in the production process, the seaweed fibers are pretreated before spinning. 6% oil is used for bulk curing during the pretreatment and the fibers are stewed for 30-36 hours before use.

[0034] The second step: color-spun wool yarn processing, the red wool-spun roving, green wool-spun roving, blue wool-spun roving and regenerated semi-dull polyester filament prepared in the first step are fed together into the color-spun wool-spun roving production device to prepare the color-spun wool-spun roving.

[0035] The red, green and blue wool-jet rovings are passed through the first roller sleeve 5, the second roller sleeve 4 and the third roller sleeve 3 of the lower control roller 2 respectively, and then the three are passed through the lower output roller sleeve 12 of the lower output roller 11 together, and then the pressure component is pressed down, so that the upper control rubber roller 1 is pressed down, and then the first rubber roller sleeve 23, the second rubber roller sleeve 22 and the third rubber roller sleeve 21 of the upper control rubber roller 1 are tightly pressed against the first roller sleeve 5, the second roller sleeve 4 and the third roller sleeve 3 of the lower control roller 2 respectively, thereby forming the first rear pressing grip input jaw, the second rear pressing grip input jaw and the third rear pressing grip input jaw for the red, green and blue wool-jet rovings respectively, and at the same time the upper output rubber roller The roller 9 is pressed down, and then the upper output rubber roller cover 10 of the upper output rubber roller 9 is tightly pressed against the lower output roller cover 12 of the lower output roller 11, thereby forming a front pressing and holding output jaw for the mixed color strands. During the first rear pressing and holding input jaw for inputting the red wool-jet roving, the first motor drives the first drive shaft to rotate, and then drives the first drive drum 8 to rotate through the first drive belt, and then drives the first roller cover 5 to rotate, and then drives the first rubber roller cover 23 to rotate synchronously, thereby actively driving the red wool-jet roving input, thereby realizing the adjustment of the feeding speed of the red wool-jet roving by adjusting the speed of the first motor. During the second rear pressing and holding input jaw for inputting the green wool-jet roving, the second motor drives the second drive shaft to rotate, and then through The second driving belt drives the second driving drum 7 to rotate, and then drives the second roller cover 4 to rotate, and then drives the second rubber roller cover 22 to rotate synchronously, thereby actively driving the green wool-jet roving to be input, so as to realize the adjustment of the feeding speed of the green wool-jet roving by adjusting the speed of the second motor. After the third, the blue wool-jet roving is input by pressing the input jaws to input the blue wool-jet roving. The third motor drives the third driving shaft to rotate, and then drives the third driving drum 6 to rotate through the third driving belt, and then drives the third roller cover 3 to rotate, and then drives the third rubber roller cover 21 to rotate synchronously, thereby actively driving the blue wool-jet roving to be input, so as to realize the adjustment of the feeding speed of the blue wool-jet roving by adjusting the speed of the third motor. The blue wool-jet roving is then gripped and output by the front pressing grip output jaw, and the grip output speed is greater than the grip input speed, so that the red wool-jet roving is subjected to a first stretching action of the ratio between the conveying speed of the front pressing grip output jaw and the input speed of the first rear pressing grip input jaw. Under the first stretching action, the linear density of the red wool-jet roving is reduced, and a red wool-jet sliver with a certain twist is obtained, and the ratio of the residual twist of the red wool-jet sliver to the twist of the red wool-jet roving is inversely proportional to the first stretching. At the same time, the fibers in the red wool-jet sliver are further straightened, and the green wool-jet roving is subjected to a second stretching action of the ratio between the conveying speed of the front pressing grip output jaw and the input speed of the second rear pressing grip input jaw.Under the action of the second drafting, the linear density of the green jet-wool roving decreases, resulting in a green jet-wool sliver with a certain residual twist, and the ratio of the residual twist of the green jet-wool sliver to the twist of the green jet-wool roving is inversely proportional to the second drafting. At the same time, the fibers in the green jet-wool sliver are further straightened, causing the blue jet-wool roving to be subjected to a third drafting action of the ratio between the conveying speed of the front pressing and holding output jaws and the input speed of the third rear pressing and holding input jaws. Under the action of the third drafting, the linear density of the blue jet-wool roving decreases, resulting in a blue jet-wool sliver with a certain residual twist, and the ratio of the residual twist of the blue jet-wool sliver to the twist of the blue jet-wool roving is inversely proportional to the third drafting. At the same time, the fibers in the blue jet-wool sliver are further straightened.

[0036] The output red, green and blue hair strands are immediately loosened and grabbed by the first opening card clothing 15 of the first opening roller 13. During this process, the first opening roller 13 rotates clockwise, so that the first opening card clothing 15 grabs the strands. During the grabbing process, the needle teeth of the first opening card clothing 15 distributed along the length direction of the middle roller shaft separate the strands in the width direction, and the needle teeth on the first opening card clothing 15 distributed along the circumference direction of the middle roller shaft separate the strands in the width direction, thereby making the red hair strands, green hair strands and blue hair strands loosened and grabbed by the first opening card clothing 15 of the first opening roller 13. The fibers on the red, green and blue jetted whiskers are transferred to the first combing roller 13 in the form of multiple fiber bundles. During the grabbing process, the twist remaining in the red, green and blue jetted whiskers makes the whiskers maintain a relatively stable shape when being grabbed by the first combing roller 13, thereby achieving uniform and stable grabbing. In the bundle splitting process, the whiskers are split into strands and then the twist of the whiskers is divided, thereby achieving uniform and consistent segmentation of the whiskers in the circumferential direction. The fiber bundles grabbed by the first combing needle clothing 15 are driven by the first combing roller 13 and then move along the first The circumferential direction of the combing roller 13 is first upward and then downward, and in the process of downward transmission, it is transported between the first combing needle clothing 15 of the first combing roller 13 and the second combing needle clothing 16 of the second combing roller 14. Between the two, the fiber bundle is subjected to the outward pushing force of the first combing needle clothing 15 and the inner pulling force of the second combing needle clothing 16, so that under the combined action of the two, the fiber bundle is completely transferred from the first combing roller 13 to the second combing roller 14. During the transfer process, the fibers in the fiber bundle on the first combing roller 13 are gradually moved from the outside to the inside under the action of the force The roller 14 is transferred, thereby increasing the separation between the fibers in the fiber bundle. At the same time, due to the increase in the distribution density of the second combing needle clothing 16 on the length of the intermediate roller shaft, the second combing needle clothing 16 enhances the bundle separation effect on the width direction of the fiber bundle, and then also improves the separation between the fibers, so that each fiber bundle is completely transferred to the second combing roller 14 in the form of more fiber bundles or single fibers. The fiber bundles grasped by the second combing needle clothing 16 are driven by the second combing roller 14 and transmitted downward along the circumferential direction of the second combing roller 14.

[0037] The sixth motor drives the cylinder 19 to rotate through the fourth drive belt, and then drives the mixing cup 17 to rotate synchronously. During the high-speed rotation of the mixing cup 17, centrifugal force is generated. Under the action of the centrifugal force, the external air flow enters from the top of the mixing cup 17 and then flows out from the air outlet 18 on the mixing ring, thereby forming a certain air flow in the mixing cup 17. Under this air flow, the fibers rotated to the lower part of the second combing roller 14 fall into the mixing cup 17. Under the action of the air flow and centrifugal force in the mixing cup 17, the fibers slide along the inner side of the mixing cup 17 and then slide to the mixing ring. At the mixing ring, the fibers of different colors are mixed along the axial direction of the mixing ring. The fibers of three different colors are combined to obtain a mixed-color fiber ring, thereby achieving uniform mixing of fibers of three different colors during multiple combining processes. As the combining continues to increase, the diameter of the mixed-color fiber ring increases, and the airflow out of the air outlet 18 decreases, thereby reducing the amount of fibers falling from the lower part of the second combing roller 14 into the mixing cup 17, and these falling fibers will continue to slide into the mixing ring for combining. At the same time, a part of the airflow entering from the top of the mixing cup 17 flows from the bottom end of the driving cylinder 19 into the cavity of the spray gun device 20, so that under this airflow flow, the mixed-color fiber ring enters the cavity of the spray gun device 20 from the bottom end of the driving cylinder 19, and as the mixed-color fiber ring falls, the fibers of the mixed-color fiber ring 17 will flow into the cavity of the spray gun device 20. The airflow out of the air outlet 18 increases again, so that the amount of fibers falling from the lower part of the second combing roller 14 into the mixing cup 17 increases accordingly, and these falling fibers will continue to slide into the mixing ring to merge, thereby forming a dynamic balance in the mixing cup 17, and the mixed fibers falling into the cavity of the spray gun device 20 are sprayed into the regenerated semi-dull polyester filament fiber mesh belt formed by the filament web forming device under the action of the compressed air gun to form a colored spun yarn. The compressed air gun works by compressing the air inhaled from the outward airflow input hole and the external air entering the cavity of the spray gun device 20 from the bottom end of the driving cylinder 19, thereby obtaining a compressed air gun high-speed spray The compressed air required for injection is then ejected at a high speed under this compressed air flow. During the fiber mesh belt processing, the needle cylinder performs a cyclic rotation motion, and then the cam in the shell drives the crochet hook to move up and down. When the crochet hook reaches the highest point, the woven coil slides under the needle tongue. When the crochet hook is lower than the needle cylinder mouth due to the rotation of the needle cylinder, the original old coil under the crochet hook slides off the crochet hook to form a new coil, thereby continuously rotating to form a regenerated semi-dull polyester filament fiber mesh belt. The output color-spun yarn is ring-detwisted by the detwisting winding device to fully detwist and ensure the fluffy characteristics of the yarn. The color-spun yarn after detwisting is continuously wound on the copper tube.

At the same time, the fibers in the green jet-wool whiskers are further straightened, so that the blue jet-wool roving is subjected to a third drafting action of the ratio between the conveying speed of the front pressing and holding output jaw and the input speed of the third rear pressing and holding input jaw. Under the action of the third drafting, the linear density of the blue jet-wool roving is reduced, and a blue jet-wool whisker with a certain residual twist is obtained. The ratio of the residual twist of the blue jet-wool whiskers to the twist of the blue jet-wool roving is inversely proportional to the third drafting. At the same time, the fibers in the blue jet-wool whiskers are further straightened. The output red, green and blue hair strands are immediately loosened and grabbed by the first opening card cloth of the first opening roller. During this process, the first opening roller rotates clockwise, so that the first opening card cloth grabs the hair strands. During the grabbing process, the needle teeth of the first opening card cloth distributed along the length direction of the middle roller shaft separate the hair strands along the width direction, and the needle teeth on the first opening card cloth distributed along the circumference direction of the middle roller shaft separate the hair strands along the width direction, thereby respectively making the red, green and blue hair strands loosened and grabbed by the first opening card cloth. The fibers on the sprayed hair strips and blue sprayed hair strips are transferred to the first combing roller in the form of multiple fiber bundles. During the grabbing process, the twist remaining in the red sprayed hair strips, green sprayed hair strips and blue sprayed hair strips makes the hair strips maintain a relatively stable shape when being grabbed by the first combing roller, thereby achieving uniform and stable grabbing. In the bundle splitting process, the hair strips are split into strands and then the twist of the hair strips is divided, thereby achieving uniform and consistent segmentation of the hair strips in the circumferential direction. The fiber bundles grabbed by the first combing needle clothing are grabbed by the first combing roller. The fiber bundles caught by the second combing needle cloth are driven by the second combing roller and transported downward along the circumferential direction of the second combing roller; The sixth motor drives the drum to rotate through the fourth drive belt, and then drives the mixing cup to rotate synchronously. During the high-speed rotation of the mixing cup, centrifugal force is generated. Under the action of the centrifugal force, the external air flow enters from the top of the mixing cup and then flows out from the air outlet on the mixing ring, thereby forming a certain air flow in the mixing cup. Under this air flow, the fibers rotated to the lower part of the second combing roller fall into the mixing cup. Under the action of the air flow and centrifugal force in the mixing cup, the fibers slide along the inner side of the mixing cup and then slide to the mixing ring. At the mixing ring, the fibers of different colors are merged along the axial direction of the mixing ring to obtain mixed colors. The fiber ring can achieve uniform mixing of three different colors of fibers during multiple merging processes. As the merging increases, the diameter of the mixed color fiber ring increases, and the air flow out of the air outlet decreases, thereby reducing the amount of fibers falling from the lower part of the second combing roller into the mixing cup, and these falling fibers will continue to slide into the mixing ring for merging. At the same time, a part of the air flow entering from the top of the mixing cup flows from the bottom end of the driving cylinder into the cavity of the spray gun device, so that under this air flow, the mixed color fiber ring enters the cavity of the spray gun device from the bottom end of the driving cylinder. As the mixed color fiber ring falls, the air flow out of the air outlet is reduced. The amount of fibers dropped from the lower part of the second combing roller into the mixing cup increases accordingly, and these dropped fibers will continue to slide into the mixing ring for merging, thereby forming a dynamic balance in the mixing cup. The mixed fibers dropped into the cavity of the spray gun device are sprayed into the regenerated semi-dull polyester filament fiber mesh belt formed by the filament web forming device under the action of the compressed air gun to form a colored spun yarn. During the operation of the compressed air gun, the air inhaled from the outwardly arranged air flow input hole and the external air entering the cavity of the spray gun device from the bottom end of the driving cylinder are compressed to obtain the compressed air flow required for high-speed injection of the compressed air gun, and then Under this compressed air flow, the mixed-color fiber ring is ejected at high speed. During the processing of the fiber mesh belt, the needle cylinder performs a cyclic rotation motion, and then the cam in the shell drives the crochet hook to move up and down. When the crochet hook reaches the highest point, the woven coil slides under the needle tongue. When the crochet hook is lower than the needle cylinder mouth due to the rotation of the needle cylinder, the original old coil under the crochet hook slides off the crochet hook to form a new coil, thereby continuously rotating to form a regenerated semi-dull polyester filament fiber mesh belt. The output color-spun yarn is ring-detwisted by the detwisting winding device to fully detwist and ensure the fluffy characteristics of the yarn. The color-spun yarn after detwisting is continuously wound on the copper tube.
