Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a cloud-soft spun yarn, its spinning process, and equipment. Background Technology

[0002] Due to environmental policies and sustainable development requirements, the chemical pollution problems of traditional softening finishing processes have become prominent. Soft yarns produced through improvements in spinning processes and equipment, with their inherent softness, better align with the trend of green manufacturing. Furthermore, with consumers increasingly demanding softness, breathability, and environmental friendliness in clothing, especially in infant products, underwear, and high-end sportswear, the application prospects for soft yarns are vast.

[0003] The current production of flexible yarn requires the use of a false twister, which leads to the need for equipment modification and periodic maintenance of wear parts during the production process, resulting in high investment costs. On the other hand, the existing equipment lacks real-time dynamic monitoring and precise adjustment of yarn tension and pressure, which can easily cause yarn breakage, loosening or over-tightening during production, resulting in uneven yarn drying.

[0015] A textile process for producing soft, cloud-like yarns is provided, applied to the aforementioned textile equipment for soft, cloud-like yarn spinning. The textile process includes:

[0016] The cleaning process adopts the following principles: frequent but less frequent handling, uniform mixing, more loosening and less beating, early removal and less breakage, less damage to fibers, and low speed.

[0017] Carding process: cylinder speed is 330r / min-380r / min, licker-in speed is 700r / min-800r / min, and flats speed is 214mm / min-266mm / min;

[0018] Pre-combining process;

[0019] Strip rolling process;

[0020] Combing process;

[0021] Final processing steps;

[0022] Roving process: Adopt the process principles of low speed, heavy pressure, light winding, and low tension;

[0023] Spinning process: Adopting the process principle of large back zone spacing and strong control, the rollers are made of materials with a Shore A hardness of 68 or higher.

[0024] Winding process: The winding machine is loaded with low tension and low speed, with a winding speed of 800m / min.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. The cloud-soft spun yarn designed in this case is composed of three or more types of cotton blends with lengths differing by more than 2mm, including fine and long-staple cotton. This reduces fiber uniformity, increases the number of fibers per unit length, increases the amount of hair less than 2mm in the cloud-soft spun yarn, and improves the yarn's softness. Furthermore, its count is above 50 English count, and its twist coefficient ranges from 240 to 280, which increases the fiber gaps in the yarn body and improves the yarn's softness. At the same time, the roving process can appropriately reduce the twist coefficient, controlling it within the range of 95-110, increasing the loose fibers on the yarn surface, which further increases the amount of hair less than 3mm in the cloud-soft spun yarn and improves the yarn's softness.

[0027] 2. This invention can monitor yarn tension in real time, effectively ensuring the tension stability of coarse yarn during drafting and winding, preventing yarn slack or breakage. Through multi-stage pressurization, combined with the buffering effects of elastic buffers, buffer plates, and transverse buffers, it can achieve low-speed, dispersed, and stable pressure, preventing yarn slippage on the rollers, avoiding "hard ends" and uneven yarn, and ensuring the uniform fineness and softness of the yarn.

[0028] 3. This invention can intelligently and dynamically adjust tension, winding pressure, and humidity to ensure uniform pressure on the yarn during winding and to ensure that the yarn continuously receives suitable humidity during the pressing process. This reduces static electricity and friction on the yarn surface, protects the elasticity and surface smoothness of the rubber roller, and prevents damage to the rubber roller due to dryness or excessive friction. It ensures uniform and stable pressing pressure, improves molding quality, and uses rubber rollers with higher hardness to reduce deformation under pressure, thereby increasing hairiness and improving softness.

[0069] In the roving process, the drafting center spacing is 36mm×52mm×54mm, the basis weight is 5.3g / 10m, the twist coefficient is 100, and the spindle speed is 900r / min. Furthermore, due to the low speed and heavy pressure used in the roving process, appropriately reducing the roving winding diameter and unwinding tension can prevent accidental fiber elongation and improve the evenness CV value. Simultaneously, using a smaller twist coefficient increases the loose fibers on the yarn surface, increasing the hairiness below 3mm to improve the yarn's softness.

[0070] The basis weight in the spinning process is 1.181 g / 100 m, the roller spacing is 18 × 29 mm, the twist coefficient is 260, and the spindle speed is 13000 r / min. Furthermore, the use of a material with a Shore A hardness of 68 or higher for the rollers in the spinning process reduces the possibility of roller deformation under pressure, appropriately weakens the control over the fibers in the drafting zone, and thus increases hairiness.

[0071] For example, in one embodiment: the end of the humidifying hollow tube 442 away from the humidifying motor 441 is connected to an external sprayer via a pipe, and the air curtain nozzle 444 is connected to an external drying jet via a pipe. A first transmission belt is fitted between the output shaft of the winding motor 193 and the inner ends of the three fixed winding rollers 343 to achieve a transmission connection, and a second transmission belt is fitted between the output shaft of the pressurizing motor 194 and the inner ends of the fixed pressurizing roller 432 and the two fixed forming rollers 51 to achieve a transmission connection.

[0072] The two winding rollers 23, the two stretching rollers 26, the three fixed winding rollers 343, the sliding pressure roller 435, the rotating pressure roller 431, the fixed pressure roller 432, and the two fixed forming rollers 51 are all made of materials with a Shore A hardness of 68 or higher.

[0073] For example, in one embodiment: when the JWF1458A roving frame used in the roving process drafts and twists the raw cotton to make roving yarn, it is sent to the spinning frame 10. Then, the roving yarn is wound sequentially through two winding rollers 23, two drafting rollers 26, three fixed winding rollers 343, a sliding pressure roller 435, a rotating pressure roller 431, a fixed pressure roller 432, and two fixed forming rollers 51. At the same time, the winding motor 193 and the pressure motor 194 are started to twist and form the roving yarn. Subsequently, two winding cylinders 21 are activated, which in turn drive the connecting cam 222 to rotate, thereby driving the two winding plates 22 to rotate, causing the two winding rollers 23 to rotate as well, thus tightening and pulling the coarse yarn. At the same time, two drafting cylinders 24 are activated synchronously, driving the two drafting triangles 25 to rotate, causing the two drafting rollers 26 to move as well, thereby applying tension to the coarse yarn. The tension monitor 32 will monitor the tension of the coarse yarn passing below in a timely manner. Furthermore, when the coarse yarn passes through the three fixed winding rollers 343, the pressure-applying triangle 344 is rotatably mounted in the winding mounting vertical plate 341 via a torsion spring. The winding pressure roller 345 within it applies uniform pre-pressure to the passing coarse yarn to ensure the uniformity of the subsequently pressurized coarse yarn and the straightening and parallelism of the fibers. Then, two pressure-applying moving cylinders 433 are activated, driving the sliding pressure roller 435 to move towards one end of the rotating pressure roller 431 to apply pressure to the coarse yarn. Simultaneously, two pressure-applying cylinders 42 are activated, thereby driving the two pressure mounting rotating plates 41 and the rotating pressure roller 431 and sliding pressure roller 435 within them to rotate, thus applying pressure to the coarse yarn. The yarn is then subjected to further pressure, which is applied slowly and dispersedly to prevent slippage of the coarse yarn on the rollers, thus avoiding "hard ends" and uneven yarn. Simultaneously, as the sliding pressure roller 435 moves towards the rotating pressure roller 431, it moves the pressure buffer plate 439 and the buffer moving plate 436 upwards, causing the elastic buffer 438 to compress. The buffer plate 439 then provides stable support to the sliding pressure roller 435 and the rotating pressure roller 431, ensuring stable rotation. Meanwhile, the transverse buffer 45 buffers the torsional vibration of the sliding pressure roller 435 and the rotating pressure roller 431 during rotation, preventing uneven yarn. Subsequently, the four forming cylinders 52 are activated, driving the two sliding forming rollers 54 downwards to shape the twisted and pressurized coarse yarn, forming the finished yarn.

[0074] For example, in one embodiment: the tension monitor 32 is electrically connected to two drafting cylinders 24 and an adjusting motor to adjust the tension of the drafting cylinders 24 according to the average length of the fine and long-staple cotton in the spun yarn and the dynamic tension fluctuation of the coarse yarn. At the same time, the adjusting motor can drive the adjusting rod 33 to rotate horizontally, adjust the position of the two adjusting paddles 331, and then adjust the position of the three pressure tripods 344, thereby adjusting the winding pressure of the three winding pressure rollers 345 on the coarse yarn.

[0075] Simultaneously, when the pressurizing element 43 applies pressure, the external sprayer and external drying jet will be activated. The sprayer generates humidifying spray that passes through the humidifying hollow tube 442 and multiple spray holes to humidify the coarse yarn below. At the same time, the drying jet generates circulating airflow through the air curtain nozzle 444. The air curtain nozzle 444 dries and evenly heats the humidified and pressurized coarse yarn above, ensuring the pressure forming effect of the subsequent forming component 50. In addition, it can also carry the humidifying spray that has humidified the coarse yarn to the upper humidifying guide plate 443 and circulate it under its guidance, ensuring the humidification effect of the coarse yarn during the pressurization process, reducing fly waste and tangling breakage, and maintaining the appropriate elasticity and surface smoothness of the rubber roller, ensuring the uniform and stable pressure during the pressurization process.

[0077] This invention can achieve:

[0078] 1. The cloud-soft spun yarn designed in this case is composed of three or more types of cotton blends with lengths differing by more than 2mm, including fine and long-staple cotton. This reduces fiber uniformity, increases the number of fibers per unit length, increases the amount of hair less than 2mm in the cloud-soft spun yarn, and improves the yarn's softness. Furthermore, its count is above 50 English count, and its twist coefficient ranges from 240 to 280, which increases the fiber gaps in the yarn body and improves the yarn's softness. At the same time, the roving process can appropriately reduce the twist coefficient, controlling it within the range of 95-110, increasing the loose fibers on the yarn surface, which further increases the amount of hair less than 3mm in the cloud-soft spun yarn and improves the yarn's softness.

[0079] 2. This invention can monitor yarn tension in real time, effectively ensuring the tension stability of coarse yarn during drafting and winding, preventing yarn slack or breakage. Through multi-stage pressurization, combined with the buffering effects of elastic buffer 438, buffer plate 439 and transverse buffer 45, it can achieve low-speed, dispersed and stable pressure, preventing yarn slippage on the roller, avoiding "hard ends" and uneven yarn, and ensuring the uniform fineness and softness of the yarn.

[0080] 3. This invention can intelligently and dynamically adjust tension, winding pressure, and humidity to ensure uniform pressure on the yarn during winding and to ensure that the yarn continuously receives suitable humidity during the pressing process. This reduces static electricity and friction on the yarn surface, protects the elasticity and surface smoothness of the rubber roller, and prevents damage to the rubber roller due to dryness or excessive friction. It ensures uniform and stable pressing pressure, improves molding quality, and uses rubber rollers with higher hardness to reduce deformation under pressure, thereby increasing hairiness and improving softness.
