With the continuous progress of textile technology and the increasing demand of consumers for product quality, the performance requirements for polyester filament are also getting higher and higher. In particular, for the production of 30D high-density light-soft special polyester fiber, the traditional spinning process has problems such as low production efficiency, unstable fiber performance and rough hand feeling. Therefore, it is of great practical significance and market value to develop a new type of spinning device and process to produce ultra-high temperature melt direct spinning 30D high-density light-soft special polyester fiber with excellent performance.

[0050] Referring to Figure 8A high-performance melt direct spinning polyester fiber spinning method, the method uses the high-performance melt direct spinning polyester fiber spinning equipment of any one of claims 1-9 to spin, the method is as follows:

[0051] S1, after the raw material is transported to the heating and conveying mechanism, it is preliminarily processed, and processed in the spinning mechanism;

[0052] S2, the internal circulation air cooling of the produced yarn is carried out, the yarn cooling is accelerated, and the surface is coated with oily paint;

[0053] S3, the uniformly coated material is transported to the hot gas pool, the inside of the device is prevented from being too dry, and then it is transported to the traction device for stretching;

[0054] S4, after the yarn is cooled, oiled, hot gas is conducted, and stretched, the yarn is sent to the drying device, and after simple drying, it is sent to the bending device, so that the line is waved at the conveying place.

[0055] S5, finally, the treated yarn is placed on the conveying table and transferred to the subsequent working device for processing.

[0056] Working principle: the feeding mechanism transports the polyester raw material to the heat preservation bin 2, the heat preservation bin 2 maintains a high temperature environment through heat insulation design, ensures that the raw material continuously melts, provides a stable material basis for subsequent spinning, and starts the motor one 4, the driving end drives the transmission rod 5 to rotate at high speed. The bevel gear one 6 outside the transmission rod 5 rotates synchronously, drives the bevel gear two 9 to rotate through gear meshing, and then drives the auger frame 8 to make spiral motion in the conveying barrel 7. The auger frame 8 uses the propelling force of the spiral blade 19 to continuously and uniformly transport the molten polyester in the heat preservation bin 2 to the spinning mechanism 3, ensuring that the spinning process has no material interruption and fluctuation.

[0057] After the molten polyester enters the spinning mechanism 3, it is extruded through the precision spinneret to form an ultrafine yarn, and the spinning forming process is formally started. The array design of the spinneret ensures uniform spacing between the yarns, laying a foundation for subsequent cooling and stretching. After the molten polyester enters the spinning mechanism 3, it is extruded through the precision spinneret to form an ultrafine yarn, and the spinning forming process is formally started. The array design of the spinneret ensures uniform spacing between the yarns, laying a foundation for subsequent cooling and stretching. The external power such as motor or transmission branch drives the transmission gear 21 to rotate, drives the gear ring 20 to rotate through gear meshing, and then makes the limiting disc 17 rotate slowly in the gas conveying tank 12. The limiting disc 17 and the fixed connecting disc 18 form a guide structure, push the blade 19 to slide along the radial direction, the top end of the blade 19 is embedded in the sliding groove of the limiting disc 17, and the bottom end is clamped with the guide rail of the connecting disc 18. Real-time change the air outlet angle and air volume distribution of the air blowing hole 13 to ensure uniform circumferential cooling of the yarn, avoid bending, shrinking or breaking caused by temperature difference.

[0058] After the yarn is guided out of the air supply tank 12, it enters the oil delivery sleeve 38 and contacts the oiling roller 39. The oiling roller 39 uniformly applies lubricating oil to the surface of the yarn by rotation, enhancing the lubricity of the yarn, reducing frictional damage during subsequent drawing, and improving the surface smoothness of the yarn. After the yarn enters the hot air mechanism 40, the hot air mechanism 40 releases a high-temperature gas stream or infrared radiation to conduct heat to the yarn. This process adjusts the internal molecular arrangement of the yarn, relaxes the drawing stress, and provides the best mechanical state for subsequent graded drawing.

[0059] The starting motor 23 drives the threaded rod 22 to rotate, and the threaded ring 24 outside the threaded rod 22 moves axially along the rod body. The moving direction is determined by the rotation direction of the threads. The rotating plate 25 is swung around the hinge point, and the rotating plate 25 is linked to the guide roller 27 through the limiting block 26, so that the distance between the multiple guide rollers 27 dynamically changes, such as gradually narrowing from wide to narrow, to perform "progressive graded drawing" on the yarn. This design avoids stress concentration during one-time drawing and significantly improves the strength and toughness of the polyester fiber.

[0060] After drawing, the yarn enters the drying mechanism 41, which quickly evaporates the residual moisture on the surface of the yarn through hot air circulation or infrared heating, ensuring the stability of the yarn shape and preventing moisture regain deformation. When the transmission rod 5 rotates, it synchronously drives the transmission mechanism 28: the transmission mechanism 28 drives the connecting rod 29 to rotate through the connecting rod, and the eccentric wheel 30 at the front end of the connecting rod 29 rotates to push the limiting rod 31 to move linearly back and forth. The sleeve ring 32 outside the limiting rod 31 drives the rack plate 34 to slide in the connecting sleeve 33, and the rack plate 34 drives the connecting gear 36 to rotate through gear meshing, and then drives the guide roller 35 to rotate, continuously guiding the yarn into the conveying mechanism 37. The conveying mechanism 37 continuously conveys the dried yarn to the subsequent process through belt or roller transmission, completing the closed loop of the entire spinning process.
