Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of polyester filament testing equipment, and in particular to a polyester filament elasticity testing device. Background Technology
[0002] In the textile industry, polyester filament is a widely used synthetic fiber material with many advantages, including high strength, good abrasion resistance, and strong chemical stability. The elasticity of polyester filament has a crucial impact on its end use. When producing sportswear, elastic fabrics, and automotive interior fabrics, it is necessary to ensure that the polyester filament provides appropriate elasticity to meet the requirements of wearing comfort and fabric elastic recovery. As people's requirements for the quality and performance of textiles continue to increase, accurate testing of polyester filament elasticity has become a key link in ensuring product quality. From the production perspective, the production process of polyester filament is complex, including multiple steps such as raw material polymerization, spinning, and stretching. Changes in parameters at each step will affect the elasticity of polyester filament. In the past, relying on experience and simple stretching tests is no longer sufficient to meet the precise control of polyester filament elasticity in the modern textile industry. During the production process, a reliable elasticity testing device is needed to monitor the quality of polyester filament, promptly identify products with non-compliant elasticity, and thus adjust production process parameters to reduce the defect rate.
[0003] The structure of the polyester filament elasticity testing device includes a clamping mechanism, a stretching mechanism, a measuring mechanism, a control mechanism, a display mechanism, a support mechanism, and a protective mechanism. During the production of polyester filament, different application scenarios have strict requirements for its elasticity. When producing polyester filament for sportswear, it needs to have good elastic recovery ability to ensure that the clothing can adapt to human movement without deformation during wear. The elasticity testing device can accurately measure the elasticity parameters of the polyester filament, ensuring that the produced polyester filament meets relevant quality standards. However, improperly fixed polyester filament will slide and shift freely during stretching, leading to inaccurate tensile data measured by the tension sensor. Furthermore, it cannot fix polyester filaments of different thicknesses, making it impossible to perform elasticity testing on polyester filaments of various specifications. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a polyester filament elasticity testing device, which aims to improve the problem in the prior art where poorly fixed polyester filaments will slide and shift freely during the stretching process, which will lead to inaccurate tensile force data measured by the tensile force sensor. At the same time, it is impossible to fix polyester filaments of different thicknesses, so it is impossible to test the elasticity of polyester filaments of various specifications.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a polyester filament elasticity testing device, comprising a base plate, two support platforms on the top of the base plate, a fixed column fixedly connected to the top of each support platform, polyester filaments arranged between adjacent fixed columns, two grooves on the top of each support platform, T-shaped blocks slidably connected to the inner walls of each groove, a clamping plate fixedly connected to the top of each T-shaped block, a hole in the middle of the clamping plate, threaded rods threadedly connected between adjacent holes, nuts threadedly connected to the opposite sides of each threaded rod, and a measuring mechanism on the top of the base plate for testing the elasticity of the polyester filaments.
[0006] As a further description of the above technical solution:
[0007] The measuring mechanism includes a fixed plate, the bottom of which is fixedly connected to the top center of the base plate. A telescopic rod is fixedly connected to the bottom left side of the fixed plate, and the other end of the telescopic rod is fixedly connected to the right side of the left support platform. A T-shaped block is fixedly connected to the bottom of the groove, and the bottom of the T-shaped block is slidably connected to the top left side of the base plate. A marker is fixedly connected to the front side of the left support platform, and a scale plate is fixedly connected to the top left front end of the base plate. A marking line is fixedly connected to the top of the scale plate.
[0008] As a further description of the above technical solution:
[0009] The top of each clamping plate is fixedly connected to a protective block, and the bottom of the base plate is fixedly connected to an anti-slip pad.
[0010] As a further description of the above technical solution:
[0011] A nameplate is fixedly connected to the front side of the support platform on the right, and a fixing plate two is fixedly connected to the top right side of the base plate.
[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, polyester filaments are first wound around the outer walls of the fixing posts on both sides, and then pressure is applied from both sides of the filaments by the clamps to fix the polyester filaments. Polyester filaments of different thicknesses can be fixed. For thinner filaments, the friction can be increased by appropriately increasing the number of turns of winding to make them firmly fixed. For thicker filaments, even if the number of turns of winding is relatively small, due to their larger diameter, the contact area with the fixing posts and clamps is also larger, so a good fixing effect can still be achieved.
[0022] 2. In this utility model, the polyester filament is stretched by pushing the support platform on the left side through the telescopic rod. Each time it reaches a certain position, it returns to its original position until the shape of the polyester filament changes when it returns to the initial position. The elasticity of the polyester filament is calculated. Through this progressive stretching method, the elastic limit of the polyester filament can be determined. During each stretching and recovery cycle, the tension and the corresponding stretching distance can be measured. Based on these data, the production process of the polyester filament can be optimized to obtain better elasticity characteristics. Attached Figure Description

Polyester filaments 5 are arranged between adjacent fixing columns 4. Two grooves 6 are opened on the top of each support platform 3, and T-shaped blocks 7 are slidably connected to the inner wall of each groove 6.

[0039] Working principle: Polyester yarn 5 is first wound around the outer wall of the fixing posts 4 on both sides. The friction between the yarn and the fixing posts 4 can initially fix the polyester yarn 5. This friction can resist the tendency of the yarn to slide during the stretching process to a certain extent. Then, the clamping plate 8 on the top of the sliding support platform 3 fixes both sides of the polyester yarn 5. The clamping plate 8 can apply pressure from both sides of the yarn to further restrict the movement of the yarn. Then, the clamping plate 8 is fixed by the combination of the threaded rod 10 and the nut 11, thus completing the fixation of the polyester yarn 5. This fixing method can fix polyester yarn 5 of different thicknesses. For thin yarns, the friction can be increased by appropriately increasing the number of turns of winding, and the clamping degree of the clamping plate 8 can be adjusted to make it firmly fixed. For thick yarns, even if the number of turns of winding is relatively small, due to its larger diameter, the contact area with the fixing posts 4 and the clamping plate 8 is also larger, so a good fixing effect can still be achieved.
[0040] The polyester filament 5 is stretched by pushing the support platform 3 on the left side using the telescopic rod 202. It is stretched to a certain position and then returned to its original position. If the polyester filament 5 does not deform, the support platform 3 continues to slide further until it returns to the initial position, at which point the shape of the polyester filament 5 changes. The position indicated by the designated mark 204 pointing to the scale plate 205 is the distance at which the polyester filament 5 deforms. The elasticity of the polyester filament 5 is then calculated. This gradual stretching method allows for very precise determination of the elastic limit of the polyester filament 5. Each stretching to a certain position and then returning to its original position allows for observation of whether the filament deforms. Compared to stretching to breakage or overstretching, this method can more precisely pinpoint the critical point at which the filament just begins to undergo plastic deformation. Furthermore, during each stretching and recovery cycle, the tension and corresponding stretching distance can be measured, resulting in a detailed deformation and elasticity relationship curve. This data can be used to optimize the production process of the polyester filament 5 to obtain better elasticity characteristics.
