Description

Technical Field

[0001] This invention relates to the field of flexible high-elastic yarn technology, specifically a process for preparing flexible high-elastic yarn. Background Technology

[0002] Flexible high-elasticity yarn is a textile material with high elasticity and flexibility, widely used in smart wearable devices, high-performance sportswear, and medical protective equipment. It is produced by blending various fibers with flexible and high-elasticity properties, thus giving the yarn its flexible and high-elasticity characteristics. During yarn production, a melt spinning machine is used to spin the flexible high-elasticity fibers into filaments.

[0003] Existing melt spinning machines require manual mixing of various fiber raw materials in advance when producing flexible high-elasticity fibers. This increases labor costs, and manual mixing is inefficient and prone to errors, thus affecting the performance of the flexible high-elasticity yarn. Summary of the Invention

[0004] The purpose of this invention is to provide a process for preparing flexible high-elastic yarn, in order to solve the problem mentioned in the background art that existing melt spinning machines require manual pre-mixing of various fiber raw materials when producing flexible high-elastic fibers, which increases labor costs, while manual mixing is inefficient and prone to errors, thus affecting the performance of flexible high-elastic yarn.

[0005] To solve the above-mentioned technical problems, the present invention provides a flexible high-elasticity yarn, comprising:

[0006] The flexible high-elastic yarn body is composed of a mixture of polyamide fiber (50-60%), spandex fiber (30-40%) and polypropylene fiber (10-20%).

[0007] Because polyamide fibers have excellent elasticity and abrasion resistance, they enable yarns to have good stretchability. Spandex fibers have extremely strong stretchability and recovery, and are soft and elastic, so they can quickly return to their original shape after stretching. Polypropylene fibers have good elasticity and chemical stability. As a result, yarns supported by the combination of these three fibers are flexible, highly elastic, abrasion-resistant and durable.

[0008] A process for preparing flexible, high-elastic yarn, characterized by comprising the following steps:

[0009] S1. The raw material slices of polyamide fiber, spandex fiber and polypropylene fiber are put into the material box and discharged out quantitatively through the material box;

[0010] S2. Filter impurities inside the raw materials discharged from the material box to keep the raw materials clean;

[0011] S3. After the raw material is discharged from the material box, it is blocked above the melt spinning machine body and is ready to be aligned and mixed.

[0012] S4. The raw materials are stirred by the agitator to ensure that they are fully and evenly mixed.

[0013] S5. The raw material is melted and spun using the melt spinning machine body, so that the flexible high-elastic yarn body is discharged outward.

[0014] A spinning element, the spinning element including a melt spinning machine body;

[0015] A metering component, which is fixedly connected to one side of the upper end of the melt spinning machine body, including a material box placed on one side of the upper end of the melt spinning machine body;

[0016] A filter element, which is fitted inside the lower end of the material box, including a filter disc fitted inside the lower end of the material box;

[0017] A blocking component, which is fixedly connected to the lower end of the filter turntable, includes a limiting rod fixedly connected to both sides of the bottom end of the filter turntable;

[0018] A stirring component, which is fixedly connected to the inside of the material cylinder, including a cover plate fixedly connected to the top of the material cylinder.

[0019] By setting up metering and filtering components, impurities in the fiber raw materials can be filtered and discharged while metering the fiber raw materials. Furthermore, the filtered fiber raw materials are blocked by blocking and stirred by the stirring component to ensure uniform mixing, thereby improving the quality of the yarn.

[0020] As a further embodiment of the present invention: the spinning component further includes an extruder fixedly connected to the top of the melt spinning machine body, a fan fixedly connected to one side of the lower end of the melt spinning machine body, a guide disc rotatably connected to the lower outer side of the melt spinning machine body, and a winding cylinder fixedly connected to the outer side of the bottom end of the melt spinning machine body.

[0021] The fiber raw material is heated and melted by an extruder and sprayed outward from the inside of the melt spinning machine. A fan is used to cool the sprayed yarn, and then the sprayed yarn is guided by a guide plate so that the winding bobbin can collect the formed yarn.

[0022] As a further embodiment of the present invention: the quantitative component further includes a material cylinder placed on one side of the upper end of the melt spinning machine body, a feeding pipe fixedly connected to the bottom end of the material cylinder, a feeding turntable sleeved inside the material box, and a through hole opened at the upper end of the feeding turntable.

[0023] The material box is fixedly connected to the outer side of the upper end of the material cylinder, and the feed pipe is fixedly connected to one side of the upper end of the extruder, with the through hole area being smaller than the material box area.

[0024] By placing the fiber raw material inside the material box, the upper fiber raw material is blocked by the upper feeding turntable, while the lower fiber raw material is discharged into the material cylinder through the through hole, thereby realizing the quantitative input of fiber raw material.

[0025] As a further embodiment of the present invention: the filter element further includes a movable rod sleeved on the outer side of the upper end of the filter turntable, a stop block fixedly connected to the top end of the movable rod, a first telescopic spring fixedly connected to the outer side of the bottom end of the stop block, and a filter screen fixedly connected to the lower end of the inside of the filter turntable.

[0026] The top of the filter screen is lower than the top of the filter turntable, and the first telescopic spring is wrapped around the outer surface of the upper end of the movable rod. The bottom end of the first telescopic spring is fixedly connected to the outer side of the upper end of the feeding turntable.

[0027] By fixing the filter screen inside the lower end of the filter disc, the raw material is discharged into the material cylinder through the filter screen. This removes impurities from the fiber raw material. After filtration, rotating the filter disc allows the impurities on the upper part of the filter screen to be carried out by the filter screen, making it easy to clean the impurities.

[0028] As a further embodiment of the present invention: the blocking member further includes baffles fixedly connected to both sides of the outer surface of the feed tube, fixed posts fixedly connected to the outer side of the baffles, a second telescopic spring placed inside the fixed posts, a movable post fixedly connected to the outer end of the second telescopic spring, an arc-shaped plate fixedly connected to the outer end of the movable post, and a partition fixedly connected to the inner side of the arc-shaped plate.

[0029] The partition extends outward through the feed pipe, and the outer surface of the limiting rod contacts the outer end of the partition. One end of the second telescopic spring is fixedly connected to the outer side of the baffle.

[0030] When the fiber material moves from the top of the filter screen down into the barrel by rotating the filter disc, the filter disc drives the limiting rod to rotate. The limiting rod drives the partition to move inward, so that the partition seals the inside of the feed pipe, thus preventing the fiber material from entering the extruder.

[0031] As a further embodiment of the present invention: the stirring component further includes a drive motor fixedly connected to the top of the cover plate, a rotating shaft fixedly connected to the output shaft of the drive motor, a stirring rod fixedly connected to the outer surface of the rotating shaft, and a scraper fixedly connected to the outer end of the stirring rod.

[0032] The rotating shaft extends downward through the cover plate, and the inner side of the scraper is in contact with the inner side of the material cylinder.

[0033] When the fiber raw material is inside the barrel, the drive motor is started. The drive motor drives the stirring rod and scraper to rotate inside the barrel through the rotating shaft, stirring the fiber raw material inside the barrel, so that the fiber raw material is mixed evenly, thereby improving the quality of the finished yarn.

[0034] As a further aspect of the present invention: the aforementioned flexible high-elastic yarn preparation process is applied to a flexible high-elastic yarn as described in claim 1.

[0035] Through these, we can gain a better understanding of a method for preparing silver ion antibacterial yarn.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows: by using a variety of fiber raw materials, the flexibility and elasticity of the yarn can be improved; by setting a fixed material box on the outside of the material cylinder, the fiber raw materials are put into the material box, and by rotating the corresponding feeding turntable, the fiber raw materials at the upper end of the material box are blocked by the feeding turntable, while the fiber raw materials at the lower end of the material box can pass through and be discharged into the material cylinder. The fiber raw materials can be efficiently and quantitatively proportioned. By setting a filter turntable, by rotating the filter turntable, the filter screen rotates into the material box, which can remove impurities from the fiber raw materials inside the material box. After the impurities are removed, the impurities can be rotated outward by the filter screen, which is convenient for cleaning the impurities.

[0037] Based on the first beneficial effect, when the filter screen rotates into the material box, the filter turntable drives the limiting rod to rotate. The limiting rod is linked with the arc plate, causing the arc plate to move inward. When the limiting rod moves past the arc plate to the outside of the baffle, the baffle moves inward under the action of the limiting rod and enters the inside of the feed pipe, thereby sealing the inside of the feed pipe and preventing the fiber raw material from entering the extruder. Then, the drive motor drives the rotating shaft to rotate, which in turn drives the stirring rod and scraper to rotate, so that the fiber raw material inside the barrel is stirred and the various fiber raw materials can be mixed evenly.

The bottom end of the first telescopic spring 34 is fixedly connected to the outer side of the upper end of the feeding turntable 24.

[0067] In this embodiment: the raw material is fed into the material box 23 and the feeding turntable 24 is rotated. When the feeding turntable 24 rotates to the position of the through hole 25 inside the material box 23, the fiber raw material at the upper end of the material box 23 moves downward through the through hole 25 to the upper end of the filter turntable 31 and is blocked by the filter turntable 31.

When the filter turntable 31 rotates, it drives the limiting rod 47 to rotate. The limiting rod 47 rotates outside the arc plate 45. The arc plate 45 guides the rotation of the limiting rod 47. When the limiting rod 47 rotates to the outside of the partition plate 46, it applies an inward force to the partition plate 46, causing the partition plate 46 to move inward and block the inside of the feed pipe 22, thereby sealing the inside of the feed pipe 22 and preventing the fiber raw material from moving downward. Then, the drive motor 52 is started, and the drive motor 52 drives the stirring rod 54 and scraper 55 through the rotating shaft 53 to stir the fiber raw material inside the material cylinder 21, so that the fiber raw material is mixed evenly. When the filter screen 35 moves out of the material box 23, the partition plate 46 moves outward under the action of the second telescopic spring 43, causing the fiber raw material to move downward into the extruder 12.
